Severe Weather Coordination Message #2 – Monday July 18th, 2011 Threat

Hello to all..

..Isolated to Scattered Strong to Severe Thundertorms with the potential for a more widespread severe weather event remain a threat for Monday Afternoon through Monday Evening. Damaging Winds, large hail and urban and poor drainage flooding are the primary threats.
..The Storm Prediction Center and NWS Taunton remain in agreement on a Slight Risk for Severe Thunderstorms for Monday. While the high category slight risk has been pulled to the west of Southern New England, there still remains a threat for a more widespread severe weather event and higher probability of severe weather as noted in the 0600 UTC SPC Day-2 Convective Outlook..
..SKYWARN Activation with Ops at NWS Taunton are likely starting as early as 11 AM to Noon lasting through late Monday Evening..

Monday is shaping up to be an active day for thunderstorms across the region and will set the stage for at least isolated to scattered strong to severe thunderstorms with damaging winds, large hail and urban/poor drainage flooding as the primary threats. If certain parameters line up, a more widespread severe weather event will be possible. Models indicate sufficient heating for destablization with strong wind shear profiles but in more of a speed shear and unidirectional environment for strong straight-line winds. This could set the stage for one or two clusters of strong to severe thunderstorms with damaging winds, large hail and very heavy rainfall that could induce urban/poor drainage flooding. Some items that could mitigate the overall threat for Monday include:

1.) Cloud cover from a convective complex expected to affect Northern New England overnight Sunday Night may delay the severe weather threat until later afternoon or mitigate the severe weather episode.

2.) West winds that could dry out dewpoints in Western New England leading to less destablization.

At this time, parameters indicate active thunderstorms in the area with isolated to scattered strong to severe thunderstorms. If the two mitigating factors above don’t occur, a more widespread severe weather event will be possible.

SKYWARN Activation with Ops at NWS Taunton are likely as early as 11 AM-Noon lasting through late evening. The next coordination message will be issued by 830 AM Monday Morning. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook:

Severe Weather Coordination Message #2 – Wednesday July 6th, 2011 Severe Weather Potential

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms remain possible over portions of Southern New Hampshire and Western and Central Massachusetts where the Storm Prediction Center (SPC) has a Slight Risk for Severe Thunderstorms with damaging winds, large hail and urban and poor drainage flooding are the primary threats..
..A conditional threat for isolated strong to severe thunderstorms exists in areas south and east of the slight risk area in interior Southern New England away from the coastal areas..
..SKYWARN Activation with Ops at NWS Taunton is possible anytime after 4 PM ET..

Severe weather threat for today is contingent on the position of a pre-frontal trough/cold front and dewpoints rising into the upper 60s over the region. Sunshine and heating through the day will occur which will start destablization of the atmosphere but it will be the winds shifting to the southwest and advecting higher humidity air and higher dewpoints and the position of the front as a trigger that will determine the scope of isolated to scattered strong to severe thunderstorms over the region. Wind shear profiles are expected to remain sufficient for isolated to scattered strong to severe thunderstorm development if the front is close enough to the region and higher dewpoint air works its way into the region. The highest risk of this occurring is over Southern New Hampshire and Western and Central Massachusetts where SPC has placed this area under a Slight Risk for severe weather. Areas south and east of the slight risk area will have a more conditional threat for isolated strong to severe thunderstorms. Damaging winds, large hail and urban/poor drainage flooding are the main threats. The threat timeframe looks to be in the late afternoon and evening hours after 4 PM ET.

SKYWARN Activation with Ops at NWS Taunton are possible late this afternoon and evening. This will be the last complete coordination message on this threat. A shortened coordination message will be issued if time allows and Ops at NWS Taunton are initiated. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:

Severe Weather Coordination Message #1 – Wednesday July 6th, 2011 Severe Weather Potential

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms possible late Wednesday Afternoon into Wednesday Night over portions of Southern New England particularly over Southern New Hampshire, Western, North-Central and Northeastern Massachusetts along and north of the Massachusetts Turnpike where the Storm Prediction Center (SPC) has placed that region in a Slight Risk for Severe Weather. Damaging Winds, Large Hail and urban/poor drainage flooding are the primary threats..
..SKYWARN Activation with Ops at NWS Taunton are possible late Wednesday Afternoon and Wednesday Night..

During the 4th of July, areas of Southeastern New Hampshire into Northeastern Massachusetts did experience strong thunderstorms with isolated severe thunderstorms in Essex County Massachusetts with more widespread activity in New Hampshire and Maine as predicted. SKYWARN Self-Activation was utilized to handle the isolated strong to severe thunderstorms that affected parts of the region. The link below is to the NWS Taunton Local Storm Report on the severe weather reports in Essex County Massachusetts from 7/4/11:

NWS Taunton 7/4/11 Local Storm Report:
http://kamala.cod.edu/offs/KBOX/1107050009.nwus51.html

On Wednesday, we will continue to have hot and humid weather over the region. A cold front will drop down into Northern New England as we get into Wednesday Afternoon and early evening and will make its way into Southern New England Wednesday Night into Thursday. Models then diverge in terms of passing this cold front through Southern New England before stalling or having the front further west of the region as we get into Wednesday Night and Thursday. This could have some impact in how far south the severe weather threat extends for the late Wednesday Afternoon and Wednesday Night timeframe. At this time, its expected that the front will be close enough to the region for isolated to scattered severe thunderstorm development extending as far south as Southern New Hampshire, Western, North-Central and Northeast Massachusetts where a Slight Risk for Severe Thunderstorms is highlighted by SPC. Areas to the south of the slight risk area away from the coast may also see an isolated to scattered strong to severe thunderstorm depending on the front position.

Shear profiles will be sufficient for severe weather. In terms of instability, some warm air in the mid-levels of the atmosphere may initially inhibit development of storms and destablization but as the cold front approaches and we get towards evening, cooling of those mid-levels should occur sufficiently to allow for isolated to scattered severe thunderstorms particularly in the SPC Slight Risk area.

SKYWARN Activation with Ops at NWS Taunton are possible late Wednesday Afternoon into Wednesday Evening. Another coordination message will be issued by 10 AM ET Wednesday. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook:

Severe Weather Coordination Message #1 – Monday July 4th, 2011 Severe Weather Potential

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms are possible in portions of Southern New England with the greatest risk in Southern New Hampshire and Northeast Massachusetts. SPC has placed New Hampshire and Maine in a Slight Risk for Severe Weather Today..
..Key potential limiters in severe weather potential today is drier air in the mid levels of the atmosphere and weak wind fields..
..SKYWARN Activation with Ops at NWS Taunton are possible this afternoon and evening..

At 910 AM, Satellite imagery shows high level clouds over Southern New England with sunshine and heating occurring through those clouds while in Northern New England conditions are sunny. A trough over Quebec will move southeast into the region today and this can be seen on Satellite imagery as well. Heating should allow for destablization of the atmosphere across the region through this afternoon. As the trough approaches the region, isolated to scattered strong to severe thunderstorms will develop as we get into the afternoon and evening hours. The greatest threat appears to be in Northern and Central New Hampshire and Maine where wind fields are a bit stronger, however, portions of Southern New Hampshire and Northeast Massachusetts in the NWS Taunton County Warning Area may see activity as the trough swings through the region. Wind fields are weaker over Southern New England and dry air in the mid-levels of the atmosphere may limit coverage of any strong to severe thunderstorms, however, if stronger wind fields enter the region and/or thunderstorms overcome the mid-level dry air, isolated to scattered strong to severe thunderstorms will develop in portions of Southern New England particularly over Southern New Hampshire and Northeast Massachusetts. Trends will be monitored throughout the day.

SKYWARN Activation with Ops at NWS Taunton are possible this afternoon and evening. This will likely be the only complete coordiantion message on today’s event. A shortened coordination message will be sent if time allows and Ops at NWS Taunton are initiated. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:

Severe Weather Coordination Message #3 – Sunday July 3rd, 2011 Severe Weather Potential

Hello to all..

..Numerous Showers and embedded Thunderstorms will slowly spread from northwest to southeast over the NWS Taunton County Warning Area. Biggest threats will be for frequent lightning and heavy rainfall causing urban/poor drainage flooding to possibly flash flooding. An Isolated Severe Thunderstorm or two capable of damaging wind or an isolated wet microburst or two cannot be ruled out..
..There is a threat for more thunderstorms on Monday. This will be discussed in greater detail later this evening..
..After coordination with NWS Taunton, SKYWARN Self-Activation will be utilized to handle this event unless more widespread strong to severe thunderstorms or flash flooding becomes evident. If Ops at NWS Taunton are initiated, a shortened coordination message will be issued if time allows..

At 1120 AM, Doppler Radar is showing an area of showers and embedded thunderstorms from Southwest New Hampshire through Western Massachusetts and Northern Connecticut. This activity is moving South-Southeast and will affect Central Massachusetts, Northeast Connecticut, Rhode Island and Eastern Massachusetts between Noon and 3 PM. Satellite imagery earlier this morning showed sun and some heating and destablization over Central Massachusetts into Rhode Island. This may allow some of the activity currently in Western New England to intensify a bit as it moves east provided it doesn’t outrun upper level air support. Further back in Eastern New York, stronger thunderstorms are organizing with heavier rainfall and possibly strong winds and are slowly moving east-southeast and may affect portions of Western Massachusetts and Northwest Connecticut later this afternoon.

The primary threats for today are heavy rainfall causing urban and poor drainage flooding to possibly flash flooding and lightning affecting outdoor activities. An Isolated strong to severe thunderstorm producing a wet microburst or damaging wind cannot be ruled out but its not the primary threat today.

There is a threat for more thunderstorms on Monday. This will be discussed in greater detail later this evening.

After coordination with NWS Taunton, SKYWARN Self-Activation will be utilized to handle this event unless more widespread strong to severe thunderstorms or flash flooding becomes evident. If Ops at NWS Taunton are initiated, a shortened coordination message will be issued if time allows. This will be the last complete coordination message for today’s event.

Severe Weather Coordination Message #1 – Sunday July 3rd, 2011 Severe Weather Potential

Hello to all..

..Slow moving cold front will bring active weather to Southern New England late Sunday Morning through Sunday Evening with numerous strong thunderstorms and the possibility of isolated severe thunderstorms. Main threats will be isolated damaging winds, urban/poor drainage to potential flash flooding, lightning and possibly hail..
..Another threat for Isolated to Scattered Severe Thunderstorms exists for late Monday Afternoon..
..SKYWARN Activation with Ops at NWS Taunton are likely Sunday. Tentative start timeframe is 11 AM Sunday. SKYWARN Activation with Ops at NWS Taunton are possible on Monday..

Sunday will have active weather as humidity will increase Saturday Night into Sunday. A slow moving cold front will move into the region. Presuming there is no convection or cloud cover from leftover convection from New York State that moves into the area, heating and destablization will commence and the weak cold front will provide focus for thunderstorm development. Wind Shear profiles are weak so the severe threat should be confined to isolated severe thunderstorms that produce isolated to a few scattered wind damage reports and possibly a few hail reports. The main threat will be urban/poor drainage flooding to flash flooding with an atmosphere that has a high moisture content. Lightning will also be a risk with thunderstorms which is a threat to outdoor activities. The threat timeframe as it looks right now is anytime after 11 AM Sunday starting out west and working its way east. The thunderstorms should wind down towards late evening around 9-10 PM.

Another threat for strong thunderstorms exists for late Monday Afternoon. This will be reviewed and updated more closely after the Sunday event.

SKYWARN Activation with Ops at NWS Taunton are likely Sunday with a tentative start time of 11 AM. SKYWARN Activation with Ops at NWS Taunton are possible on Monday. Another coordination message will be posted by 1130 PM this evening. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook:

Amateur Radio Field Day/Severe Weather Coordination Message #3A – June 25th, 2011 230 PM Post

Hello to all..

..The following is a shortened Amateur Radio/Severe Weather Coordination Mesage to cover current convective trends..
..Satellite Imagery as of 215 PM shows breaks of sunshine are covering much of Southern New England this afternoon and evening. In areas of most heating, temperatures have risen to the upper 60s to mid 70s. This is allowing for atmosphere destablization particularly in Western Massachusetts, and Connecticut. Doppler Radar at 215 PM is showing an area of showers and possible weak thunderstorms over Eastern New York. This will be monitored as it moves east into portions of Western New England around or after 4 PM ET, possibly reaching Central and Eastern New England after 6-7 PM ET..
..SKYWARN continues to monitor for possible thunderstorm or isolated to scattered strong to severe thunderstorm activity for this afternoon/evening. SKYWARN Activation with Ops at NWS Taunton remains possible for later this afternoon and evening. Another shortened coordination message will be posted if Ops at NWS Taunton are initiated or as thunderstorm/convective trends dictate an update most likely around 5-6 PM ET this evening..
