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

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

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:

Severe Weather Coordination Message #1 – Sunday July 15th 2012 Severe Weather Potential

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms are possible across much of Southern New England Sunday Afternoon and Evening. Strong to Damaging Winds, large hail and urban/poor drainage flooding are the primary threats..
..Threat timeframe is after 2 PM Sunday Afternoon and will be contingent on sunshine and degree of instability in the atmosphere..
..SKYWARN Activation with Ops at NWS Taunton are possible Sunday Afternoon and Evening..

A warm front will make its way through Southern New England Sunday Afternoon and Evening bringing with it oppressive heat and humidity for the first half of this week. Along the warm front, isolated to scattered strong to severe thunderstorms could organize in Eastern New York, New Jersey and Eastern Pennsylvania and make its way into Southern New England after 2 PM in western areas and after 4 PM in eastern areas with strong to damaging winds, large hail and urban/poor drainage flooding as the primary threats. The threat will be contingent on the amount of sunshine and destablization that can take place ahead of the front. Wind shear values should be sufficient for the potential for isolated to scattered strong to severe thunderstorms presuming full destablization is realized. The Storm Prediction Center (SPC) and NWS Taunton are 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 are possible Sunday Afternoon and Evening. Another coordination message will be issued by 1 PM Sunday Afternoon. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook:

Severe Weather Coordination Message #2 – Saturday July 7th, 2012 Severe Weather Potential Reduced for Much of Area – Monitoring Continues

Hello to all..

..Message delayed until after the latest 1630 UTC/1230 PM EDT SPC Day-1 Convective Outlook was issued..
..Due to Cloud cover and light showers covering portions of Southern New England not seen on weather models yesteday, the severe weather threat looks to be confined to portions of Connecticut and largely south and west of the NWS Taunton Coverage Area. A Severe Thunderstorm Watch has been issued for Litchfield, Fairfield and New Haven Counties of Connecticut until 7 PM this evening. There is the possibility that some severe weather activity could affect areas close to the watch in the NWS Taunton Coverage Area in Connecticut but this is currently a low probability..
..SKYWARN Self-Activation will monitor the progress of today’s activity. Ops at NWS Taunton now seem less likely but are possible if activity is able to organize in the northern part of a short line of thunderstorms approaching the area..
..This will be the last coordination message for today unless a significant upgrade to the situation occurs and Ops at NWS Taunton are initiated. Below is the NWS Taunton Hazardous Weather Outlook, SPC Day-1 Convective Outlook and Severe Thunderstorm Watch Information for areas just outside of the NWS Taunton Coverage Area..

Severe Weather Coordination Message #1 – Saturday July 7th, 2012 Severe Weather Potential

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms are likely Saturday Afternoon and Evening across much of Southern New England. Damaging Winds, Large Hail and urban and 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 Saturday Afternoon and Evening..
..SKYWARN Activation with Ops at NWS Taunton are likely Saturday Afternoon and Evening..

A cold front will approach the region Saturday Afternoon and Evening bringing more seasonable temperatures and less humidity for the first half of next week. As the front approaches, the atmosphere should be unstable with good wind shear profiles aloft. Some other severe weather parameters are not quite as favorable but the approach of the cold front into an unstable atmosphere with reasonably strong wind shear should allow for isolated to scattered strong to severe thunderstorms to develop over the region with damaging winds, large hail and urban/poor drainage flooding as the primary threats. The threat timeframe will be Saturday Afternoon into Saturday Evening and SPC and NWS Taunton are in agreement on a slight risk for severe weather for that timeframe.

SKYWARN Activation with Ops at NWS Taunton are likely on Saturday. Another coordination message will be issued by Noon Saturday. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook:

Severe Weather Coordination Message #3 – Wednesday July 4th Severe Weather Potential

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms remain possible late this Wednesday Afternoon and Evening across much of the NWS Taunton coverage area with some models indicating that Southern New Hampshire and Eastern Massachusetts may be at greatest risk for isolated to scattered severe weather activity. Damaging winds, large hail and urban and poor drainage flooding are the primary threats. SPC and NWS Taunton maintain the 5% probability of severe weather risk over the area..
..Much of the region is clearing out this morning in the wake of earlier showers and isolated downpours which will allow temperatures to rise into the lower 90’s with high humidity. Much of the region will remain dry but isolated to scattered locations could receive a shower or thunderstorm and a couple to few locations could see a strong to severe thunderstorm..
..SKYWARN Self-Activation is likely to monitor the severe weather potential for later Wednesday Afternoon and Wednesday Evening. Ops at NWS Taunton remain possible to likely for the same time period..

At 1030 AM, Satellite and Radar imagery indicate clearing conditions across much of Southern New England. Clouds across Southeast Massachusetts and Southern Rhode Island will move out of the area allowing for temperatures to rise quickly with much higher humidity there as well. Temperatures are expected to reach the lower 90s.

As this occurs, the atmosphere will destabilize over the course of the day with good wind shear profiles over the region. Warmer temperatures aloft and the lack of a trigger will keep the atmosphere capped for a good portion of the day across the region and this will mean little in the way of shower and thunderstorm activity during the day. As we get into late this afternoon and this evening, an impulse will approach the region from southern Canada and this may allow for the cap to be broken allowing 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 is conditional on the impulse being able to break the cap and tap into the unstable environment and wind shear aloft. Models seem to indicate that Southern New Hampshire and Eastern Massachusetts may be an area to watch though all areas should monitor the situation. As stated in this coordination message and prior messages, much of the region will remain dry but isolated to scattered locations could receive a shower or thunderstorm and a couple to few locations could see a strong to severe thunderstorm.

SKYWARN Self-Activation is likely to monitor the severe weather potential for later Wednesday Afternoon and Wednesday Evening. Ops at NWS Taunton remain possible to likely for the same time period. This will be the last full coordination message on today’s threat. Given the 4th of July holiday and many outdoor activities, a shortened coordination message will be issued later today, likely prior to or around 800 PM this evening, either indicating the threat is cleared or if Ops at NWS Taunton are initiated or SKYWARN Self-Activation is actively monitoring activity over the region.

Severe Weather Coordination Message #2 – Wednesday July 4th 2012 Potential

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms continue to be possible for Wednesday Afternoon and Evening across much of Southern New England. Damaging Winds, large hail and urban and poor drainage flooding are the primary threats..

..Uncertainities remain with what occurs with convection during the early morning hours of Wednesday and what impacts that has on the environment for later Wednesday. Anyone with outdoor interests particularly given the amount of them occurring for July 4th/Independence Day activities should continue to monitor later forecasts. It will not be a washout and many areas will remain dry but events impacted by thunderstorms, particularly strong to severe thunderstorms, could have issues so monitoring later forecasts remains prudent..

..SKYWARN Activation with Ops at NWS Taunton remain possible to likely for Wednesday Afternoon and Evening..

The Storm Prediction Center (SPC) has continued with a severe weathre threat level of ‘See Text’/5% severe weather probability owing to uncertainties in what evolves for convection and storms during the early morning hours Wednesday. This could get upgraded if conditions become more certain for severe weather for later Wednesday Afternoon and evening.

The two different scenario setup as indicated in the last coordination message remains in play. Wind fields should be sufficient for strong to severe thunderstorm development, the keys for severe weather development later Wednesday Afternoon and Evening are the amount of cloud cover over the region from any shower and thunderstorm activity Wednesday Morning and whether expected heating and destablization is realized and sufficient triggering for thunderstorms to develop. The information from the previous message on the two scenarios is brought forward to this message below.

The first sceneario would be that convection that occurs during Wednesday Morning will mitigate heating and destablization lessening the threat for showers and thunderstorms and a severe weather threat for later in the day Wednesday. The second scenario is that this activity moves through quickly and allows for clearing, heating and destablization that would allow for at least isolated to scattered strong to severe thunderstorms and even the potential for a more potent severe weather outbreak. The forecast is uncertain in the regards to the severe weather magnitude but odds favor at least isolated to scattered strong to severe thunderstorms with damaging winds, large hail and urban and poor drainage flooding as the primary threats during Wednesday Afternoon and Evening. If enough clearing and other parameters line up, a more potent severe weather episode would be possible. Given the amount of outdoor activities for July 4th, future forecasts should be monitored closely for changes as the initial set of convection moves through Wednesday Morning and what that means for potential severe weather later Wednesday.

SKYWARN Activation with Ops at NWS Taunton remain possible to likely for Wednesday. Another coordination message will be issued by 1100 AM Wednesday Morning to update the July 4th severe weather potential. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook:

This morning the Storm Prediction Center (SPC) reduced the threat level for severe weather from Slight Risk to ‘See Text’/5% severe weather probability owing to uncertainties in what evolves for convection and storms during the early morning hours Wednesday. They also stated, however, that a Slight risk could be reintroduced in later outlooks.

Essentially, two scenarios could evolve for July 4th. The first sceneario would be that convection that occurs during Wednesday Morning will mitigate heating and destablization lessening the threat for showers and thunderstorms and a severe weather threat for later in the day Wednesday. The second scenario is that this activity moves through quickly and allows for clearing, heating and destablization that would allow for at least isolated to scattered strong to severe thunderstorms and even the potential for a more potent severe weather outbreak.
