Severe Weather Coordination Message #4 – Tuesday 7/24/12 Severe Weather Potential

July 24, 2012 Rob Macedo Leave a comment

Hello to all..

..A few strong thunderstorms affected the region early this morning with winds up to 40 MPH, small hail, heavy downpours and frequent lightning..
..A Cold front will approach the region this afternoon and evening. The cold frontal timing is expected to be around the time of peak heating which will set the stage for isolated to scattered strong to severe thunderstorms with damaging winds, large hail, and urban and poor drainage flooding as the main threats..
..The Storm Prediction Center (SPC) has kept Central and Eastern New England in a Slight Risk of severe weather for late Tuesday Morning through Tuesday Evening and NWS Taunton is in agreement..
..SKYWARN Activation with Ops at NWS Taunton are likely late Tuesday Morning through Tuesday Evening..

Early this morning, a line of strong but non-severe thunderstorms went through the region bringing 40 MPH wind gusts, small hail, frequent lightning and heavy downpours. This activity has moved offshore. Satellite imagery shows fairly clear skies to allow for heating and destabilization. Wind shear profiles and other severe weather parameters should be sufficient for isolated to scattered strong to severe thunderstorms with damaging winds, large hail and urban/poor drainage flooding as the primary threats. It is noted that SPC has continued a slight risk for severe weather for Central and Eastern New England and this is the area to be watched for this afternoon and tonight.

SKYWARN Activation with Ops at NWS Taunton are likely late Morning Tuesday through Tuesday 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 #3 – Tuesday 7/24/12 Severe Weather Potential

July 24, 2012 Rob Macedo Leave a comment

Hello to all..

..Strong to Severe Thunderstorm activity stayed to the north and west of the NWS Taunton coverage area today..
..A Cold front will approach the region Tuesday. The timing of the cold front and whether or not it is near the time of peak heating will dictate the potential of isolated to scattered strong to severe thunderstorms with damaging winds, large hail, and urban and poor drainage flooding as the main threats..
..The Storm Prediction Center (SPC) has upgraded Central and Eastern New England to a Slight Risk of severe weather for late Tuesday Morning through Tuesday Evening and NWS Taunton is in agreement..
..SKYWARN Activation with Ops at NWS Taunton are likely late Tuesday Morning through Tuesday Evening..

Today, severe weather stayed to the north and west of the NWS Taunton coverage area with a couple brief strong thunderstorms entering extreme Southwest New Hampshire and Western Massachusetts this evening. As we get into Tuesday, a cold front will approach the region from the west. The timing of this cold front will be key to severe weather potential. If it approaches too early, the severe weather threat could be mitigated, however, if it comes into the region in the late morning or afternoon timeframe, isolated to scattered strong to severe thunderstorms with damaging winds, large hail and urban/poor drainage flooding would be likely over the area. It is noted that SPC has placed portions of Central and Eastern New England in a Slight Risk for severe weather which is an upgrade from the prior Day-2 Convective Outlook and NWS Taunton is in agreement. By Tuesday Morning, we should have a better idea of the severe weather potential and timing of the cold front but it appears the severe weather potential for Tuesday is greater than Monday at this time.

SKYWARN Activation with Ops at NWS Taunton are likely late Morning Tuesday through Tuesday Evening. The next coordination message will be issued by 9 AM ET Tuesday. Below is the NWS Taunton Hazardous Weather Outlook, and SPC Day-2 Convective Outlook:

Severe Weather Coordination Message #2 – Monday 7/23/12 and Tuesday 7/24/12 Severe Weather Potential

July 23, 2012 Rob Macedo Leave a comment

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms remain possible over Interior Southern New England on Monday. Damaging winds, large hail and urban and poor drainage flooding are the primary threats..
..The Storm Prediction Center (SPC) has continued 5% probabilities of severe weather over much of Southern and Eastern New England with a Slight Risk for severe weather over Western, Northern New York, most of Vermont, Northern New Hampshire, Western Maine now extending into extreme Southwest New Hampshire and extreme Western Massachusetts and NWS Taunton is in agreement..
..An additional potential for severe weather exists for Tuesday and will be covered in future coordination messages after the Monday Severe Weather Potential has passed..
..SKYWARN Activation with Ops at NWS Taunton are possible on Monday Afternoon and Evening and again on Tuesday Afternoon and evening..

At 700 AM Doppler Radar showed an area of showers and possibly embedded thunderstorms over South-Central and Southeast New York moving into Western New England with some additional shower activity in Eastern Massachusetts. Satellite imagery shows clearing north and west of this activity. Further upstream, a trough with some shower and thunderstorm activity is moving east-southeast from the Lake Huron area. This trough and activity in Lake Huron may be close enough to Southern New England for isolated to scattered strong to severe thunderstorms with damaging winds, large hail, and urban and poor drainage flooding as the primary threats. The threat timeframe will be during Monday Afternoon and evening. Low severe weather probabilities have been introduced by SPC for much of Southern New England with a Slight risk for severe weather over Western and Northern New York, most of Vermont, Northern New Hampshire, extreme Western Maine and now extending into extreme Southwest New Hampshire and Western Massachusetts. The proximity of the front, cloud cover, and wind shear over the area will determine the risk for severe weather for Monday Afternoon and Evening.

There is also the potential for severe weather on Tuesday. This will depend on the timing of the cold front over the area as well as wind shear and cloud cover over the region similar to Monday. This will be discussed in greater detail after the Monday severe weather potential has passed.

SKYWARN Activation with Ops at NWS Taunton are possible Monday Afternoon and Evening. This will be the last complete coordination message on Monday’s severe weather potential. 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, SPC Day-1 and SPC Day-2 Convective Outlook:

A warm front will move through the region overnight. After that passes through the region, a trough will develop over portions of New York and New England as the heat and humidity increase. The trough maybe close enough to Southern New England for isolated to scattered strong to severe thunderstorms with damaging winds, large hail, and urban and poor drainage flooding as the primary threats.

Severe Weather Coordination Message #3 – Wednesday 7/18/12 Severe Weather Potential

July 18, 2012 Rob Macedo Leave a comment

Hello to all..

..Scattered to Numerous Strong to Severe Thunderstorms likely today across much of Southern New England with the highest risk area for strong to severe thunderstorms along and south of the Mass. Pike. Damaging winds, large hail and urban and poor drainage flooding are the main threats..
..Threat timeframe will be centered anytime after Noon today lasting through tonight. The Storm Prediction Center (SPC) and NWS Taunton are in agreement on a slight risk for severe weather for today..
..SKYWARN Activation with Ops at NWS Taunton will commence at 11 AM ET today lasting through Wednesday Evening..

At 730 AM, Satellite imagery shows mostly clear skies with some high clouds in parts of Western New England. A cold front that will begin to usher in cooler and more seasonable temperatures is currently over Western Maine through South-Central New Hampshire and Vermont through Central New York and will move southeast. Overnight low temperatures were in the upper 70’s to lower 80s and with mostly clear skies, significant heating and destablization is expected. Wind shear profiles are sufficient for strong to severe thunderstorm development. Most parameters are favorable for scattered to numerous strong to severe thunderstorms today with damaging winds, large hail and urban and poor drainage flooding as the main threats. The threat timeframe for severe weather will be anytime after Noon today with the greatest threat in areas along and south of the Mass. Pike, however, all areas should monitor. SPC and NWS Taunton and surrounding NWS offices are in agreement on a slight risk for severe weather for Massachusetts, Rhode Island and Connecticut.

SKYWARN Activation with Ops at NWS Taunton will commence at 11 AM today lasting through Wednesday Evening. This will be the last coordination message on today’s threat. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:

Severe Weather Coordination Message #2 – Tuesday 7/17/12 Self-Activation/Wednesday 7/18/12 Severe Weather Potential

July 18, 2012 Rob Macedo Leave a comment

Hello to all..

..SKYWARN is self-activated this evening for portions of Southern New Hampshire for isolated strong to severe thunderstorms that are near the area. This should gradually wane overnight..
..Scattered to Numerous Strong to Severe Thunderstorms are likely across much of Southern New England from midday Wednesday to Wednesday Evening. Damaging Winds, Large Hail, and urban/poor drainage flooding are the primary threats. The Storm Prediction Center (SPC) and NWS Taunton are in agreement on a Slight Risk for Severe Weather Across Much of Southern New England including coastal areas..
..SKYWARN Activation with Ops at NWS Taunton will commence at 11 AM Wednesday through Wednesday Evening..

The bulk of Tuesday’s severe weather occurred over Northern New England, however, an isolated severe thunderstorm snuck into Manchester, NH causing isolated damage. See the Local Storm Report below:

http://kamala.cod.edu/offs/KBOX/1207180041.nwus51.html

Wednesday has the potential to be an active severe weather day across much of Southern New England as a cold front brings an end to the latest round of heat and humidity affecting the region. There should be sufficient heating and destablization ahead of the cold front to allow for an unstable atmosphere. Wind Shear profiles also appear favorable for scattered to numerous strong to severe thunderstorms with damaging winds, large hail and urban and poor drainage flooding as the primary threats. Threat timeframe could start as early as midday Wednesday lasting through Wednesday Evening. SPC and NWS Taunton are in agreement on a slight risk for severe weather and it is noted that much of the region is in the 30% severe weather probability area.

SKYWARN Activation with Ops at NWS Taunton will commence at 11 AM lasting through Wednesday Evening. Another coordination message will be issued by 9 AM Wednesday Morning. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook:

Severe Weather Coordination Message #1 – Tuesday July 17th, 2012 Severe Weather Potential

July 17, 2012 Rob Macedo Leave a comment

Hello to all..

..The Storm Prediction Center (SPC) has placed portions of Southern New Hampshire, Western, North-Central and Northeast Massachusetts in a Slight Risk for Severe Weather for later this Tuesday afternoon and Evening. Damaging Winds, large hail and urban/poor drainage flooding are the primary threats..
..Threat is contingent on southward extent of a disturbance that will affect portions of Northern New England and whether short-range computer models indicating much greater instability over Southern New England verify versus other reliable models indicating much less instability over the region..
..SKYWARN Activation with Ops at NWS Taunton are possible later this afternoon and evening if severe weather threat materializes in the NWS Taunton portion of the SPC Slight Risk area..

A conditional severe weather threat exists for northern portions of the NWS Taunton coverage area from Southern New Hampshire, Western, North-Central and Northeastern Massachusetts for later this afternoon and tonight as SPC has placed this region in a slight risk for severe weather with damaging winds, large hail and urban and poor drainage flooding as the primary threats. Weather models, even this close to the event, are struggling to resolve instability parameters ahead of a disturbance that will affect Northern New England with severe weather and how far south the extent of the severe weather will be. Short range reliable computer models are indicating that instability will increase allowing for severe weather in the southern portions of the area SPC has placed in Slight Risk. Other reliable computer models, however, keep the threat north of the NWS Taunton coverage area. Enough risk exists at this time to issue a severe weather coordination message covering the threat.

An additional severe weather risk exists for Wednesday for much of the NWS Taunton coverage area. This will be covered in later coordination messages Tuesday Night into Wednesday.

SKYWARN Activation with Ops at NWS Taunton are possible later this afternoon and tonight. This will be the only complete coordination message issued covering today’s 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 #2 – Sunday July 15th 2012 Severe Weather Potential – Activation and Ops Starting at 3 PM ET

July 15, 2012 Rob Macedo Leave a comment

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms are likely in Southwest New Hampshire, Western and Central Massachusetts and Connecticut late this afternoon and evening. These storms could reach portions of Northeast Massachusetts and Northwest Rhode Island this evening. Strong to Damaging Winds, large hail and urban/poor drainage flooding are the primary threats..
..SKYWARN Activation with Ops at NWS Taunton will commence at 3PM Sunday Afternoon..

A warm front will make its way through Southern New England this Afternoon and Evening bringing with it oppressive heat and humidity for the first half of this week. At 1130 AM, satellite imagery shows some high clouds over the area but plenty of sunshine allowing for heating and destablization. Doppler Radar at 1130 AM shows some activity in Central and Eastern New York that could gradually become better organized as it gets into Western parts of New England after 300 PM today. The unstable atmosphere combined with wind shear values should be sufficient for isolated to scattered strong to severe thunderstorms with strong to damaging winds, large hail and urban and poor drainage flooding as the primary threats. The primary threat area is over Southwest New Hampshire, Western and Central Massachusetts and Connecticut after 300 PM today but could reach portions of Northeast Massachusetts and extreme Northwest Rhode Island this evening. The Storm Prediction Center (SPC) and NWS Taunton remain in agreement on an isolated to scattered threat of strong to severe thunderstorms for Sunday Afternoon and evening.

SKYWARN Activation with Ops at NWS Taunton will commence at 3 PM this Sunday Afternoon. This will be the last coordination message on today’s threat. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-1 Convective Outlook:
