Severe Weather Coordination Message #1 – Thursday May 28th 2015 Severe Weather Potential

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms possible to likely again today, Thursday, across much of interior Southern New England. The Storm Prediction Center, SPC, has placed much of interior Southern New England in a slight risk for severe weather with a marginal risk surrounding the slight risk area. Strong to damaging winds, hail and heavy rainfall with possible urban to poor drainage flooding are the primary threats. Threat timeframe is in the early to mid afternoon to early evening timeframe so a bit earlier than Wednesday and some interior areas of Eastern New England could be affected..
..SKYWARN Activation with Ops at NWS Taunton are likely later today and tonight..

Yesterday, portions of Western Massachusetts were impacted by strong to severe thunderstorms with strong to damaging winds as a trough swung through the area. As expected, activity weakened as it moved eastward. Below is the NWS Taunton Local Storm Report on the pockets of wind damage that occurred with the severe thunderstorms in Western Massachusetts as well as one lightning induced structure fire:

For today, a cold front that will bring a bit cooler and less humid conditions will swing through Southern New England this afternoon and tonight. Wind shear values and instability values should be sufficient for isolated to scattered strong to severe thunderstorms across interior Southern New England starting as early as the first part of this afternoon and lasting through early evening. The key possible limiting factor is whether dry air at the mid-levels moves in and limits storm development. If that doesn’t occur, at minimum, isolated to scattered strong to severe thunderstorms will affect portions of interior Southern New England and extend into Eastern New England. The Storm Prediction Center, SPC, has placed much of interior Southern New England in a slight risk for severe weather with a marginal risk surrounding the slight risk area. Strong to damaging winds, hail and heavy rainfall with possible urban to poor drainage flooding are the primary threats.

SKYWARN Activation with Ops at NWS Taunton are likely later today and tonight. This will be the only complete coordination message on today’s severe weather potential. 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:
