Wind/Coastal Flood & Fire Weather Coordination Message #1 – Tuesday 9/22/20 – Strong Wind/Coastal Flood/Fire Weather Potential

September 22, 2020 Rob Macedo

Hello to all…

..Hurricane Teddy will pass well offshore of Southern New England but the gradient between Teddy and High Pressure over Southern New England will bring strong to damaging winds for Cape Cod and the Islands with strong wind gusts over East and South Coastal Massachusetts along with high surf and the potential for minor coastal flooding at the time of high tide Tuesday Afternoon. While winds will be less in the interior, fire weather will be a concern due to dry conditions, low humidity and breezy conditions..
..A High Wind Warning is now in effect for Nantucket through 11 PM Tuesday Evening for sustained winds of 30-40 MPH with gusts to 60 MPH. A Wind Advisory is in effect for Cape Cod and Martha’s Vineyard from 9 AM to 8 PM Tuesday for sustained winds of 20-30 MPH with gusts to 50-55 MPH. A Wind Advisory is in effect for Eastern and Plymouth Counties for sustained winds of 20-30 MPH with gusts of 40-50 MPH. Other coastal areas could see wind gusts near 40 MPH today. These winds will cause isolated to scattered pockets of tree and wire damage and isolated power outages..
..A Coastal Flood Advisory is now in effect from 2-7 PM Tuesday for Eastern Essex, Suffolk, Eastern Norfolk, Eastern Plymouth, Barnstable, Dukes and Nantucket Counties of Massachusetts for minor coastal flooding on shore roads at the time of high tide Tuesday Afternoon/early evening..
..A High Surf Advisory is now in effect through 8 PM Wednesday for Eastern Essex, Eastern Plymouth, Cape Cod and the Islands, South Coastal Massachusetts and Rhode Island for the dangers of rip currents and high surf along these coastal areas..
..A Red Flag Warning for fire weather is in effect through 9 PM Tuesday Evening for Massachusetts and Rhode Island as low humidity, recent dry weather and drought conditions along with strong winds could increase the fire risk for the region. A Special Weather Statement has been issued for Northern Connecticut regarding the fire risk..
..SKYWARN Self-Activation will monitor the strong to damaging wind and coastal flood potential in East and South Coastal Massachusetts and Rhode Island. This is the only coordination message on today’s weather unless a significant change to the situation occurs.

Severe Weather Coordination Message #2 – Saturday 8/29/20 Severe Weather Potential

August 29, 2020 Rob Macedo

Hello to all…

..Isolated to Scattered Strong to Severe thunderstorms are possible across much of Southern New England with the highest potential in Western Massachusetts and Northern Connecticut between about 4-10 PM Saturday. The Storm Prediction Center (SPC) has placed all of Southern New England in a marginal risk for severe weather Saturday with a slight risk for severe weather back into Eastern New York where conditions will be more favorable..
..SKYWARN Self-Activation will monitor the severe weather potential for Saturday..

Another round of severe weather occurred on Thursday but more isolated in nature in the NWS Norton coverage area as the warm front never quite made it through enough of Southern New England to get into our coverage area. Areas of Southwest and South-Central Connecticut saw significant severe weather and the NWS Brookhaven New York confirmed an EF1 Tornado from Bethany to North Haven CT along with multiple microbursts and other communities of New Haven County CT. The NWS Boston/Norton Local Storm Report along with the NWS Brookhaven NY Local Storm Report and Public Information Statement on damage surveys are listed below:

https://kamala.cod.edu/offs/KOKX/2008290329.nwus51.html (Connecticut Tornado confirmed via damage survey)

For Saturday, a warm front will be able to push through Southern New England and there will be strong wind shear again in the upper levels of the atmosphere for severe thunderstorm development. Instability, however, could be quite marginal due to cloud cover. If the strong wind shear conditions in the upper levels of the atmosphere can overcome lower instability values or more clearing develops to allow for greater instability, the severe weather potential in our region would be increased and this will bear watching. At this time, the greatest chance for isolated to scattered strong to severe thunderstorms is in Western Massachusetts and Northern Connecticut. The potential is more conditional farther east given the potential for cloud cover to hold on longer in this area then in western parts of the area.

SKYWARN Self-Activation will monitor the severe weather potential for Saturday. This will be the last coordination message on this severe weather potential as we shift into operations mode.

Severe Weather Coordination Message #2 – Thursday 8/27/20 Severe Weather Potential

August 27, 2020 Rob Macedo

Hello to all…

..The potential exists for a high-end severe weather outbreak over portions of Southwest Massachusetts and Connecticut with a now more marginal to slight risk for severe weather over Rhode Island along with Central Massachusetts for Thursday Afternoon and Evening as the position of the warm front is a little more south and west than yesterday’s update but still through much of Connecticut with areas of Northeast Connecticut, Rhode Island and Southeast Mass near this front.
..A Tornado Watch is now in effect for Berkshire County Massachusetts and Litchfield County Connecticut until 700 PM EDT. Its possible this watch could expand into other parts of Connecticut and Southwest Massachusetts later today..
..The Storm Prediction Center (SPC) has placed Southwest Massachusetts and Connecticut in an Enhanced Risk for severe weather and surrounding that enhanced risk area in Northeast Connecticut, Central and Eastern Massachusetts and Rhode Island are now in a marginal to slight risk of severe weather. Strong to damaging winds, hail, frequent lightning, heavy downpours leading to urban and poor drainage flooding and isolated tornadoes are all potential threats..
..SKYWARN Self-Activation will closely monitor the severe weather potential for Thursday through 9 PM EDT..

After a one day reprieve in severe weather potential, a potentially high-end severe weather outbreak is possible over portions of Southern New England. The headlines depict current thinking including the warm frontal position being a bit more south and west than yesterday’s update. Key factors in this severe weather potential include:

1.) Position of the warm front and how far north and east it gets. The further north and east it gets, the greater the severe weather potential including the greater the risk across a larger portion of Southern New England. If the warm front remains south and west of the region, it would mute the severe weather potential. At this time the warm frontal position modeled best aligns with the slight to enhanced risk areas meaning the warm front should get through Southwest Massachusetts particularly along and south of the Mass Pike into Western and Central Connecticut with Eastern Connecticut, Rhode Island and Eastern Massachusetts having a more conditional risk with the warm front right on top of these areas..
2.) Sufficient heating and destabilization after warm frontal passage to allow for high instability.
3.) Wind shear parameters and parameters for rotation are high for this potential severe weather outbreak.

SKYWARN Self-Activation will closely monitor the severe weather potential for Thursday with the timeframe anytime through 9 PM EDT today. This will be the last coordination message as we shift into operations mode.

Severe Weather Coordination Message #1 – Thursday 8/27/20 Severe Weather Potential

August 27, 2020 Rob Macedo

Hello to all…

..The potential exists for a high-end severe weather outbreak over portions of Southwest Massachusetts, Connecticut and Rhode Island Thursday Afternoon and Evening with other areas north and east needing to monitor pending the position of the warm front, currently expected to be through at least West-Central Massachusetts and sufficient clearing for heating and destabilization over areas south and west of this warm front..
..The Storm Prediction Center (SPC) has placed Western to South-Central Massachusetts and Rhode Island in Enhanced Risk for Severe Weather with a slight risk for severe weather and surrounding the enhanced risk area, a marginal to slight risk of severe weather for the rest of Central and Eastern Massachusetts. Strong to damaging winds, hail, frequent lightning, heavy downpours leading to urban and poor drainage flooding and isolated tornadoes are all potential threats..
..SKYWARN Self-Activation will closely monitor the severe weather potential for Thursday with the timeframe anytime between 12-9 PM EDT..

1.) Position of the warm front and how far north and east it gets. The further north and east it gets, the greater the severe weather potential including the greater the risk across a larger portion of Southern New England. If the warm front remains south and west of the region, it would mute the severe weather potential. At this time the warm frontal position modeled best aligns with the slight to enhanced risk areas meaning the warm front should get through Southwest Massachusetts particularly along and south of the Mass Pike and just west of I-495 through Rhode Island and Connecticut.
2.) Sufficient heating and destabilization after warm frontal passage to allow for high instability.
3.) Wind shear parameters and parameters for rotation are high for this potential severe weather outbreak.

Severe Weather Coordination Message #3 – Tuesday 8/25/20 Severe Weather Potential

August 25, 2020 Rob Macedo

Hello to all…

..Scattered to Numerous Strong to Severe Thunderstorms likely Tuesday presuming sufficient moisture and instability in the atmosphere associated with a strong cold front that will bring an end to the heat and humidity of the last few days. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats. The Storm Prediction Center (SPC) has continued a Slight Risk for Severe Weather across all of Southern New England. Timeframe is 12-8 PM Tuesday..
..SKYWARN Self-Activation will be active for the severe weather potential for Tuesday Afternoon and Evening..

While less in coverage and intensity than this weekend, a few strong to severe thunderstorms developed over Southern New England this afternoon. The NWS Boston/Norton Local Storm Report on today’s severe weather event is listed below and photos of the last 3 days of severe weather will be posted today:

NWS Boston/Norton Local Storm Report – Monday 8/24/20 Severe Weather Event:
https://kamala.cod.edu/offs/KBOX/2008250201.nwus51.html

Not much change to the headlines regarding Tuesday’s severe weather potential. SPC had considered an enhanced risk upgrade for Southern New England but is holding off at this time as it remains unclear how much strong to severe thunderstorm coverage there will be. This could still happen as we get into this afternoon. While the greatest potential maybe across Connecticut, Rhode Island and Southeast Massachusetts, the slight risk area covers all of New England and all areas should monitor.

Tuesday, a strong cold front will swing through New England and with it bring a more widespread potential for strong to severe thunderstorms across all of New England. The headlines depict the current thinking and the caveats to the potential for more widespread severe weather for Tuesday. Key factors include:

1.) Timing of the cold front to allow for sufficient heating and destabilization.
2.) Amount of mid-level dry air in the atmosphere and moisture convergence as there needs to be sufficient moisture in the atmosphere for severe thunderstorm development and to sustain updrafts.
3.) Wind shear profiles will be the strongest of the last few days and will need to be monitored if sufficient heating, destabilization and moisture are available for more widespread pockets of wind damage from strong to severe thunderstorms.
4.) There is some cloud cover and a dying area of showers that will slow heating slightly but satellite imagery indicates rapid clearing behind it. Provided moisture remains in place and heating returns as expected, this should allow for scattered to numerous strong to severe thunderstorms in the region.

SKYWARN Self-Activation will be active for the severe weather potential for Tuesday. This will be the last coordination message as we shift into operations mode.

Severe Weather Coordination Message #1 – Monday 8/24/20 and Tuesday 8/25/20 Severe Weather Potential

August 24, 2020 Rob Macedo

Hello to all…

..Another Round of Isolated to Scattered Strong to Severe Thunderstorms are likely Monday Afternoon and evening across much of Southern New England away from the south coast of Mass and Rhode Island for Monday Afternoon and Evening. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats. Threat timeframe is 2-8 PM EDT Monday Afternoon and Evening..
..The Storm Prediction Center (SPC) has placed most of Southern New England except for Southeast Coastal Massachusetts and Rhode Island in a marginal risk for severe weather for Monday..
..Scattered to Numerous strong to severe thunderstorms are likely Tuesday across all of New England with the same main threats as Monday but potentially more widespread than the last few days. SPC has all of New England in a Slight Risk for severe weather for Tuesday. Timeframe for severe weather potential Tuesday is from 2-8 PM EDT though could start as early as a 11 AM or 12 PM EDT Tuesday..
..SKYWARN Self-Activation will occur both Monday and Tuesday for the severe weather potential for Monday and Tuesday..

It has been an active weekend for severe weather for portions of Southern New England. We are working toward posting Facebook Photo Albums for both severe weather events today pending when the severe weather from today starts up. Pictures, video and reports from the severe weather events of Saturday 8/22 and Sunday 8/23 can be sent to the email address pics@nsradio.org or via our WX1BOX Facebook/Twitter feeds with credit given to the SKYWARN Spotter/Amateur Radio report for the information unless otherwise indicated. The latest Local Storm Reports for the severe weather events of Saturday 8/22 and Sunday 8/23 are listed below:

NWS Boston/Norton Local Storm Report – Saturday 8/22/20 Severe Weather Event:

NWS Boston/Norton Local Storm Report – Sunday 8/23/20 Severe Weather Event:
https://kamala.cod.edu/offs/KBOX/2008241407.nwus51.html

In a similar setup to the weekend, another round of isolated to scattered strong to severe thunderstorms are likely in portions of Southern New England today anytime between 2-8 PM EDT. While much of Southern New England is in a marginal risk for severe weather, an area within the marginal risk for severe weather with higher severe weather potential is area along and south of the Mass Pike but away from the south coast of Rhode Island and Massachusetts. All areas within the marginal risk area should continue to monitor today’s potential.

For Tuesday, a strong cold front will move through the area with higher wind shear profiles. The timing of the cold front is in question and could affect instability parameters but a more widespread severe weather event is likely on Tuesday. Cold frontal timing could increase the severe weather potential if its passage is later in the afternoon. SPC has placed the area in a slight risk for severe weather for Tuesday given the potential for more widespread coverage of strong to severe thunderstorms.

SKYWARN Self-Activation will occur both Monday and Tuesday for the severe weather potential for Monday and Tuesday. The next coordination message focusing on the Tuesday severe weather potential will be posted by 1030 PM Monday evening pending how the Monday severe weather potential evolves.
