Severe Weather Coordination Message #2 – Thursday 9/12/13-Friday 9/13/13 Severe Weather Potential

Hello to all..

..Isolated to Scattered Strong to Severe Thunderstorms possible to likely late Thursday Afternoon and Evening extending into Friday Morning across much of Southern New England. Strong to Damaging Winds, hail and urban/poor drainage flooding are the primary threats..
..SKYWARN Activation with Ops at NWS Taunton likely late Thursday Afternoon into early Friday Morning..

Yesterday brought Isolated strong to severe thunderstorms to portions of Western Massachusetts and Southwest New Hampshire with the bulk of heavier activity back into Eastern New York, Vermont, North-Central New Hampshire and Maine as while conditions were unstable in the region, most of the triggering mechanisms stayed north and west of our region. Below is the Local Storm Report from yesterday’s severe weather event:

For later Thursday Afternoon into Friday Morning, a strong cold front will bring an end to the short duration of heat over the region. Temperatures today will mostly be in the 80s with possibly a few areas touching 90 degrees. Conditions won’t be quite as unstable as yesterday but instability parameters will still be sufficient coupled with strong wind shear values and a focus for convection between the cold front and pre-frontal trough to set the stage for isolated to scattered strong to severe thunderstorms with strong to damaging winds, hail and urban/poor drainage flooding as the primary threats. The extent of the severe weather threat will be determined by the timing of the cold front and the amount of instability available as the cold front moves through the region. There is the possibility the cold front will slow down as it moves across the area which may extend the threat for thunderstorms with urban and poor drainage flooding and possibly strong to damaging winds into Friday Morning for parts of Eastern Massachusetts and Rhode Island. Portions of Western New England are in a Slight Risk for severe weather as noted by the Storm Prediction Center (SPC).

SKYWARN Activation with Ops at NWS Taunton are likely later this afternoon and tonight. This will be the only complete coordination message on 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:
