Storm Coordination Message #2 – Wednesday Night 10/16/19-Thursday 10/17/19 Coastal Storm Potential

Hello to all…

..Strong Coastal Storm system brings the threat of heavy rainfall, strong to damaging winds and even isolated strong to severe thunderstorms to Southern New England Wednesday Night into Thursday Morning with the potential of strong to damaging winds continuing through late Thursday Afternoon..
..The Storm Prediction Center (SPC) has continued Eastern Connecticut, Rhode Island and Southeast Massachusetts in a marginal risk for severe weather with strong to damaging winds and perhaps even the low risk of an isolated, brief tornado for late tonight and early Thursday Morning..
..A High Wind Warning is now in effect from 1 AM to 5 PM Thursday for Cape Cod and the Islands, Eastern Essex and Eastern Plymouth Counties of Massachusetts for sustained winds of 30-40 MPH with gusts to 60-65 MPH. These winds will cause isolated to scattered pockets of tree and wire damage and isolated to scattered power outages..
..A Wind Advisory is now in effect from 10 PM Wednesday Evening to 6 PM Thursday Evening for the rest of the NWS Boston/Norton coverage area including Northern Connecticut, Rhode Island, Western, Central and the remainder of Eastern Massachusetts for sustained winds of 20-30 MPH with gusts to 50 MPH and isolated higher wind gusts possible. These winds will cause isolated pockets of tree and wire damage and isolated power outages..
..A Flood Watch is now in effect from 10 PM Wednesday Evening through Thursday Morning for Northern Connecticut, and Western and Central Massachusetts for rainfall of 2-3″ with locally higher amounts of up to 5″ possible. This rainfall may cause significant urban and poor drainage flooding. Due to recent dry conditions, most if not all small rivers and streams will remain in their banks..
..SKYWARN Self-Activation will monitor the storm system overnight and during the day Thursday. Ops at NWS Boston/Norton are possible but would be focused on daytime operations as needed with overnight activity monitored by self-activation. It is most likely we will use SKYWARN Self-Activation and remote monitoring of repeaters for rainfall reports, wind damage and wind gust measurement reports and any flooding reports..

A strong coastal storm system will cause heavy rainfall and strong to damaging winds across much of Southern New England with even the risk of isolated severe thunderstorms in Southeast New England with strong to damaging winds and an isolated brief tornado as potential threats. The heavy rainfall will be during the overnight hours and end near or before the Thursday Morning commute with the severe weather risk late tonight into early Thursday Morning before daybreak. The strong to damaging winds will occur overnight and again during the day on Thursday lasting into the late afternoon/early evening. The headlines depict current thinking with the key changes being a High Wind Warning for Cape Cod and the Islands, Eastern Plymouth and Eastern Essex Counties of Massachusetts, the expansion of the Wind Advisory across the entire NWS Boston/Norton Coverage area and a Flood Watch for Western and Central Massachusetts and Northern Connecticut. Key factors include:

1.) Winds overnight could be strong to damaging and enhanced by convective heavy downpours and thunderstorms that can drag strong to damaging winds down to the surface and there is even the potential for isolated severe thunderstorms with even the risk of an isolated brief tornado in Southeast New England hence the marginal risk for severe weather in this area.
2.) Strong to damaging winds will occur on the back side of the storm system as it moves away from the area as well. The track of the storm system over Southern New England and the potential for more areas to be exposed to the east side of the system has resulted in the Wind Advisory expansion as well as a conversion to High Wind Warnings for Cape Cod and the Islands and expanding those warnings into Eastern Essex and Eastern Plymouth Counties of Massachusetts.
3.) Understanding that the rainfall did not materialize from last week’s nor’easter, the track of this storm is very different and tracking over Southern New England increasing confidence for heavy rainfall. Given recent dry conditions, flooding should be confined to urban and poor drainage areas but could be widespread enough to cause an impact so a flood watch has been issued for this hazard.
4.) With such a strong and dynamic system, it will bear close watching for higher impacts assuming the fully intensity modeled is realized and based on track guidance.

SKYWARN Self-Activation will monitor the storm system overnight and during the day Thursday. Ops at NWS Boston/Norton are possible but would be focused on daytime operations as needed with overnight activity monitored by self-activation. It is most likely we will use SKYWARN Self-Activation and remote monitoring of repeaters for rainfall reports, wind damage and wind gust measurement reports and any flooding reports. This will be the last complete coordination message for this storm system. A shortened coordination message will be posted if Ops at NWS are initiated and time allows for an update.

..The Storm Prediction Center (SPC) has placed Eastern Connecticut, Rhode Island and Southeast Massachusetts in a marginal risk for severe weather with strong to damaging winds and perhaps even the low risk of an isolated, brief tornado for late tonight and early Thursday Morning..
..A High Wind Watch is now in effect for Cape Cod and the Islands for Thursday Morning into Thursday Afternoon with a Wind Advisory in effect from 10 PM Wednesday Evening to 7 AM Thursday Morning for sustained winds 25-35 MPH with gusts to 50-55 MPH overnight and potentially as high as 60 MPH with isolated higher gusts Thursday. These winds will cause isolated to scattered pockets of tree and wire damage and isolated power outages..
..A Wind Advisory is now in effect from 10 PM Wednesday Evening to 6 PM Thursday Evening for South Coastal Massachusetts and Rhode Island including Eastern Kent County Rhode Island for sustained winds of 20-30 MPH with gusts to 50 MPH and isolated higher wind gusts possible. These winds will cause isolated pockets of tree and wire damage and isolated power outages..
..A Wind Advisory is now in effect from Midnight to 6 PM Thursday for Eastern Essex, Southeast Middlesex, Suffolk, Eastern Norfolk and Eastern Plymouth Counties of Massachusetts for sustained winds of 25-35 MPH with gusts to 55 MPH and isolated higher gusts. These winds will cause isolated to scattered pockets of tree and wire damage and isolated power outages..
..A Wind Advisory is now in effect from 7 AM to 5 PM Thursday for Western Essex, Southern Worcester, Western Plymouth, Central Middlesex, Western Norfolk and Northern Bristol Counties of Massachusetts and Providence and Western Kent Counties of Rhode Island for sustained winds of 15-20 MPH with gusts to 50 MPH and isolated higher gusts possible. These winds will cause isolated pockets of tree and wire damage and isolated power outages..
..Heavy Rainfall of 1-3″ is expected across much of Southern New England with isolated higher amounts of 3-4″ possible in localized areas. This rainfall may cause areas of localized urban and poor drainage flooding in most prone areas..
..SKYWARN Self-Activation will monitor the storm system overnight and during the day Thursday. Ops at NWS Boston/Norton are possible but would be focused on daytime operations as needed with overnight activity monitored by self-activation..

Storm Coordination Message #2 – Wednesday Evening 10/9/19-Friday 10/11/19 Coastal Storm Potential

Hello to all…

..Long Duration Coastal Storm to Affect Southern New England starting late Wednesday Afternoon with some strong winds in gusts to around 40 MPH with stronger and more damaging winds, heavy rainfall and coastal flooding possible to likely particularly in Southeast New England Thursday into Friday..
..A High Wind Warning is now in effect from 2 AM Thursday Morning through 600 AM Friday Morning for Cape Cod and the Islands for sustained winds of 30-40 MPH with gusts to 60 MPH and isolated higher gusts likely. A Wind Advisory is in effect for Eastern Plymouth County Massachusetts from 2 AM Thursday Morning through 6 AM Friday Morning for sustained winds of 25-35 MPH with gusts to 50 MPH. These winds could cause isolated to scattered pockets of tree and wire damage and isolated to scattered power outages. Other coastal areas near the High Wind Warning and Wind Advisory areas should closely monitor the strong to damaging wind potential with wind gusts of 40-45 MPH possible in areas closest to the wind headlines..
..A Coastal Flood Advisory is in effect for Nantucket from 9 AM-12 PM Thursday for the Thursday Morning high tide cycle for the potential of minor coastal flooding at the time of the Thursday Morning high tide cycle..
..A Coastal Flood Watch remains in effect from Thursday Evening through late Thursday Night for Eastern Plymouth County Massachusetts and Cape Cod and the Islands from Thursday Evening through late Thursday Night for the potential of minor to moderate coastal flooding at the time of high tide Thursday Night..
..A Flood Watch is in effect for all of Southeast Massachusetts including Cape Cod and the Islands and Norfolk and Suffolk Counties of Massachusetts for a widespread 3-6″ of rain. Isolated higher amounts of up to 8″ are possible on Cape Cod and Plymouth County of Massachusetts with even some localized 10″ amounts possible. This will result in the potential for urban and poor drainage flooding and possibly small river and stream flooding..
..SKYWARN Self-Activation is likely with this storm with Amateur Radio Call-Up Nets centered in Southeast Massachusetts. Ops at NWS Boston/Norton are possible during the day Thursday..

A long duration coastal storm is expected to affect Southern New England starting Wednesday Evening through Friday. The headlines depict the latest thinking with a conversion of the High Wind Watch to a High Wind Warning for Cape Cod and the Islands and a Wind Advisory for Eastern Plymouth County Massachusetts and a Flood Watch now posted for Southeast Massachusetts. Key factors for this long duration storm is as follows:

1.) The storm intensity and interaction of the storm with high pressure to the north and the strength and area affected for strong to damaging winds. At this time the strongest winds are expected in Eastern Plymouth County Massachusetts and Cape Cod and the Islands. Coastal and perhaps some southeastern interior areas should closely monitor the progress of the strong to damaging winds. A closer track to the area could allow those winds to get stronger in those areas. With the expected very wet ground and stronger winds, the wind damage potential will bear watching.
2.) The storm track has held steady but all models are depicting the potential for very heavy rainfall for Southeast Massachusetts and the Flood Watch has been issued for that reason. Rainfall reports over the entire storm will be needed and flooding of urban and poor drainage areas are likely and perhaps also affecting rivers and small streams as well.
3.) The storm effects will last into Friday for both strong to damaging winds, heavy rainfall and coastal flooding and this will be covered in future coordination messages. The worst conditions at this time are expected on Thursday during the day and at night.
4.) While astronomical tides are low, wave action and the possibility for multiple high tide cycles of strong to damaging winds, building seas and waves will allow for some minor to moderate coastal flooding in the north and east facing areas of Eastern Plymouth County Massachusetts and Cape Cod and the Islands. This is another aspect that will bear watching. It is noted the Thursday Morning high tide could bring minor coastal flooding to Nantucket and a Coastal Flood Advisory is now in effect for that high tide for Nantucket.

SKYWARN Activation with Ops at NWS Boston/Norton are possible during the day Thursday. Another coordination message will be posted by 6 AM Thursday Morning.

..SKYWARN Activation with Ops at NWS Boston/Norton are possible during the day Thursday..

A long duration coastal storm is expected to affect Southern New England starting late Wednesday Afternoon and lasting through Thursday Night and possibly into Friday. The headlines depict the latest thinking. Key factors for this long duration storm is as follows:

1.) The storm intensity and interaction of the storm with high pressure to the north and the strength and area affected for strong to damaging winds.
2.) The storm track which has been closer to Southern New England in recent model trends which could result in heavier rainfall in Southeast New England and the potential for stronger and more damaging winds in southeast New England with stronger winds potentially extending further north in Southern New England.
3.) The storm effects could last into Friday for both strong to damaging winds, heavy rainfall and coastal flooding and this will be covered in future coordination messages.

Severe Weather Coordination Message #1 – Thursday 9/26/19 Severe Weather Potential

Hello to all…

..Strong Wind Gusts in convective heavier showers and isolated strong to possibly even a severe thunderstorm is possible across Southern New England late this afternoon through early this evening. Lightning and other risks are low but strong winds in the upper level of the atmosphere and ahead of a cold front and any convective showers and thunderstorms may allow for strong winds to transport down to the surface allowing for isolated tree and power line damage and isolated power outages..
..The Storm Prediction Center (SPC) has placed parts of Connecticut, Rhode Island and Southeast Massachusetts in a marginal risk for severe weather today..
..SKYWARN Self-Activation will monitor this potential for late Thursday Afternoon and evening. This will be the only coordination message posted on this potential unless a significant upgrade to the situation occurs and time allows for an update.

Hurricane Dorian Coordination Message #2 – Late Friday Night 9/6/19-Saturday 9/7/19 Tropical Storm Conditions on Cape Cod and the Islands

Hello to all…

..Hurricane Dorian is expected to pass southeast of Nantucket Island late Friday Night into early Saturday Morning. The track will bring a period of strong to damaging winds and heavy rainfall to Cape Cod and the Islands during this timeframe with high surf and rip currents over portions of the Southern New England coast..
..A Tropical Storm Warning is in effect for Cape Cod and the Islands for the potential of sustained winds of 30-40 MPH with gusts to 50-60 MPH. These winds could cause isolated to scattered pockets of tree and wire damage and isolated power outages along with minor coastal flooding particularly around Nantucket. There is the potential for 1-4″ of rain in the Tropical Storm Warning area with the worst conditions between 2 AM-12 PM Saturday..
..Areas of Southeast New England nearest the tropical storm warning area may see wind gusts to 30-40 MPH and up to 1.5″ of rain. There is also the possibility of a band of rainfall in Western New England that could produce up to 1″ of rain not directly associated with Dorian..
..Track uncertainty of around 50 miles is still present. A track closer to the coast would mean somewhat higher impacts in the tropical storm warning area and perhaps stronger impacts north and west of the current Tropical Storm Warning area. A track further offshore would confine tropical storm impacts to Nantucket Island Massachusetts..
..A High Surf Advisory is in effect from 4 PM Friday Afternoon through 6 PM Saturday Evening for South Coastal Massachusetts and Rhode Island and from 6 AM-6 PM Saturday for Eastern Essex and Eastern Plymouth Counties of Massachusetts..
..SKYWARN Self-Activation will monitor for tropical storm conditions on Cape Cod and Islands. The 146.955-Barnstable Repeater will be monitored during this tropical storm event. It is noted that these impacts will be similar to a quick hitting nor’easter. The hurricane will remain offshore so hurricane conditions are not expected..

Hurricane Dorian is expected to track southeast of Nantucket Island Late Friday Night into Saturday Morning. This will result in tropical storm conditions over Cape Cod and the Islands where a Tropical Storm Warning is now in effect. The headlines depict the current thinking. Key factors remain as follows:

1.) Eventual track of Dorian. As stated in the headlines, the track uncertainty is about 50 miles and a slightly closer track by this amount may allow for slightly stronger tropical storm force conditions over Cape Cod and the Islands and could extend those conditions a little further north and west while a track 50 miles further offshore would mean impacts confined to Nantucket Island.
2.) The hurricane combined with strong high pressure along with warm ocean temperatures and slightly cooler air aloft has the potential to allow for an expanding wind gradient that will support the stronger wind gusts that our tropical storm strength in the watch area if Dorian’s track is close enough.

SKYWARN Self-Activation will monitor for tropical storm conditions on Cape Cod and Islands. The 146.955-Barnstable Repeater will be monitored during this tropical storm event. It is noted that these impacts will be similar to a quick hitting nor’easter. The hurricane will remain offshore so hurricane conditions are not expected. This will likely be the last coordination message on Dorian unless a significant upgrade to the situation occurs and time allows for an update.

Severe Weather Coordination Message #2 – Wednesday 9/4/19 Severe Weather Potential

Hello to all…

..Isolated to scattered strong to severe thunderstorms are likely from north and west of a Boston to Providence line through much of Southern New England. Strong to damaging winds, heavy rainfall leading to urban and poor drainage flooding are the main threats but there is also a secondary risk of large hail and an isolated tornado..
..The Storm Prediction Center (SPC) has placed much of Southern New England from Windham County Connecticut, Middlesex, and western Essex counties of Massachusetts north and west in a slight risk for severe weather with a marginal risk for severe weather in Southeast New England except for Cape Cod and the Islands..
..Timeframe for severe weather is expected to be between 2-9 PM Wednesday and a Mesoscale Convective Discussion has been issued indicating an 80% chance of a watch for much of Southern New England.
..SKYWARN Activation with Ops at NWS Boston/Norton is likely between 1-2 PM Wednesday Afternoon..

Clearing is occurring across much of the marginal and slight risk areas late this morning allowing for increased instability. There will be strong winds aloft above what is required for severe weather potential with strong forcing and a trigger with a cold front in the region. The extent of the severe weather potential will be based on the level of instability. There will also be some turning in the atmosphere which may allow for an isolated tornado and large hail risk. Given the clearing trend and if it continues, this may allow for a fairly potent severe weather event particularly in the slight risk severe weather area and will be monitored closely.

Severe Weather Coordination Message #1 – Wednesday 9/4/19 Severe Weather Potential

Hello to all…

..Isolated to scattered strong to severe thunderstorms are possible from north and west of a Boston to Providence line north and west across much of Southern New England. Strong to damaging winds, heavy rainfall leading to urban and poor drainage flooding are the main threats but there is also a low risk of large hail and an isolated tornado..
..The Storm Prediction Center (SPC) has placed much of Southern New England northwest of a Boston to Providence line through Eastern New York and Northern New England in a marginal risk for severe weather with the potential of an upgrade to slight risk in later outlooks if more instability materializes. Timeframe for severe weather is expected to be between 1-9 PM Wednesday..
..SKYWARN Activation with Ops at NWS Boston/Norton is likely by 1 PM Wednesday Afternoon. A more complete coordination message will be posted by 1000 AM Wednesday Morning on Wednesday’s severe weather potential. Below is the NWS Boston/Norton Hazardous Weather Outlook, Enhanced Hazardous Weather Outlook and SPC Day-2 Convective Outlook..

Storm Coordination Message #1 – Wednesday Night 8/28/19-Thursday Morning 8/29/19 – Flash Flood/Heavy Rainfall Potential

Hello to all…

..A cold front moving across New England late Wednesday Afternoon through Thursday Morning coupled with moisture from offshore Tropical Depression Erin will set the stage for widespread general rainfall and the potential for flash flooding of urban and poor drainage areas and possibly some small streams. A Flash Flood Watch is in effect for Central and Eastern Massachusetts and Rhode Island through late Wednesday Night for 2-4″ of rainfall with localized amounts of up to 5″ possible. Western areas should monitor but are expected to receive less rainfall..
..An isolated strong to severe thunderstorm with strong to damaging wind, frequent lightning and heavy downpours cannot be ruled out during the evening and overnight hours..
..SKYWARN Activation with Ops at NWS Boston/Norton will commence by 530 PM EDT Wednesday Evening through late tonight to monitor flash flooding and any isolated severe weather potential..

A cold front approaching from New York State will move its way through New England tonight and tap into a moisture feed from Tropical Depression Erin to bring heavy downpours and perhaps a few embedded thunderstorms to the area. The headlines depict the current thinking regarding heavy rainfall and flood potential. Key factors include:

1.) Whether any heavy training rainfall will track over a given area to result in the higher end rainfall amounts.
2.) Whether any heavy training rainfall will track over vulnerable urban areas or areas of more flashy small streams/rivers.
3.) Any thunderstorm development that enhances heavy rainfall.

SKYWARN Activation with Ops at NWS Boston/Norton will commence by 530 PM EDT Wednesday Evening through late tonight to monitor flash flooding and any isolated severe weather potential. Below is the NWS Boston/Norton Flash Flood Watch Statement, Hazardous Weather Outlook and Enhanced Hazardous Weather Outlook:
