Severe Weather Coordination Message #1 – Monday 7/25/16 Severe Weather Potential/Saturday 7/23/16 Post Severe Weather Summary

Hello to all..

..After a one day reprieve in heat, humidity and severe weather, both will return on Monday to Southern New England..
..Scattered to possibly numerous strong to severe thunderstorms likely across much of Southern New England late Monday Afternoon through late Monday Night. Strong to damaging wind, hail, urban and poor drainage flooding from heavy rainfall and frequent lighting are the main threats..
..The Storm Prediction Center (SPC) has placed portions of Western and Central Massachusetts and Western and Central Connecticut in a slight risk for severe weather with a marginal risk for severe weather for much of the rest of Southern New England..
..Intense Heat and Humidity has prompted the issuance of a heat advisory for Hampden County Massachusetts and Hartford County Connecticut..
..SKYWARN Activation with Ops at NWS Taunton likely starting around 3-4 PM lasting through late Monday Night..

Saturday 7/23/16 brought another round of severe weather as a gust front out ahead of a line of strong to severe thunderstorms caused widespread pockets of wind damage in Massachusetts and more isolated reports of wind damage in Rhode Island. A few isolated reports of large hail were also received in Northeast Massachusetts with wind damage from a few severe thunderstorms ahead of the line of thunderstorms and the gust front. Any additional photos or late reports can be sent to pics@nsradio.org, via our Facebook/Twitter feeds, or to my rmacedo@rcn.com email address. Credit will be given to the SKYWARN Spotter/Amateur Radio Operator for the pictures/video unless otherwise indicated. The pictures will be sent to NWS, media, and emergency management.

After Sunday’s less humid and slightly cooler temperatures, conditions will heat up on Monday with higher humidity levels as temperatures will soar to the mid and upper 90s. A trough/cold front will move into the region later Monday Afternoon and Monday Evening. High instability levels will be present by mid to late afternoon and evening across the region. Shear levels will be marginal in the mid-afternoon but increase and be more sufficient for severe weather potential by the late afternoon Monday into Monday Evening. This will set the stage for another round of scattered to possibly numerous strong to severe thunderstorms for much of Southern New England. Similar to the last couple of events, the key factors that will determine the severe weather potential include:

1.) Any morning cloud debris/cloud cover in the morning that affects daytime heating and lowers instability levels.
2.) If the strong wind shear values do not overlap the favorable instability levels presuming factor 1 does not change the potential.
3.) Timing of the trough/cold front to tap into increasing wind shear and higher instability levels in the atmosphere.

SKYWARN Activation with Ops at NWS Taunton likely starting around 3-4 PM lasting through late Monday Night. Another coordination message will be posted by 9 AM Monday Morning. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook as well as the NWS Taunton Heat Advisory Statement:
