Severe Weather Coordination Message #1 – Sunday July 3rd, 2011 Severe Weather Potential
Hello to all..
..Slow moving cold front will bring active weather to Southern New England late Sunday Morning through Sunday Evening with numerous strong thunderstorms and the possibility of isolated severe thunderstorms. Main threats will be isolated damaging winds, urban/poor drainage to potential flash flooding, lightning and possibly hail..
..Another threat for Isolated to Scattered Severe Thunderstorms exists for late Monday Afternoon..
..SKYWARN Activation with Ops at NWS Taunton are likely Sunday. Tentative start timeframe is 11 AM Sunday. SKYWARN Activation with Ops at NWS Taunton are possible on Monday..
Sunday will have active weather as humidity will increase Saturday Night into Sunday. A slow moving cold front will move into the region. Presuming there is no convection or cloud cover from leftover convection from New York State that moves into the area, heating and destablization will commence and the weak cold front will provide focus for thunderstorm development. Wind Shear profiles are weak so the severe threat should be confined to isolated severe thunderstorms that produce isolated to a few scattered wind damage reports and possibly a few hail reports. The main threat will be urban/poor drainage flooding to flash flooding with an atmosphere that has a high moisture content. Lightning will also be a risk with thunderstorms which is a threat to outdoor activities. The threat timeframe as it looks right now is anytime after 11 AM Sunday starting out west and working its way east. The thunderstorms should wind down towards late evening around 9-10 PM.
Another threat for strong thunderstorms exists for late Monday Afternoon. This will be reviewed and updated more closely after the Sunday event.
SKYWARN Activation with Ops at NWS Taunton are likely Sunday with a tentative start time of 11 AM. SKYWARN Activation with Ops at NWS Taunton are possible on Monday. Another coordination message will be posted by 1130 PM this evening. Below is the NWS Taunton Hazardous Weather Outlook and SPC Day-2 Convective Outlook:
