Severe Weather Coordination Message #2 9/5/17-9/6/17 Severe Weather and Flash Flood Potential and Special Announcement: Hurricane Irma Amateur Radio Hurricane Net Activation Plans

Leave a comment

Hello to all…

..Isolated to scattered strong to severe thunderstorms are possible to likely across Western and North-Central Massachusetts and Northwest Connecticut but timing is for late Tuesday Afternoon into Tuesday Night where the Storm Prediction Center (SPC) has maintained the region in a marginal to slight risk for severe weather. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding to flash flooding are the main threats..
..As we get into later Tuesday Night into Wednesday Night, the severe weather threat wanes across western areas but heavy rainfall and localized urban and poor drainage flooding to flash flooding is possible across portions of Southern New England and there is a marginal risk for severe weather over a localized area of Rhode Island and Southeast Massachusetts area for Wednesday..
..SKYWARN Self-Activation will monitor activity later this afternoon and tonight. SKYWARN Activation with Ops at NWS Taunton are possible as we get into Wednesday for urban and poor drainage flooding and flash flooding..
..This message also contains a Special Announcement regarding Hurricane Irma Amateur Radio Hurricane Net activation plans..

A strong cold front will be moving towards New England on Tuesday and will have sufficiently strong wind shear values and moisture pooling ahead of the front. The cold frontal timing is slower than originally projected and will now affect the region late Tuesday Afternoon into Tuesday Night with the best timeframe between 5-10 PM. This may limit the coverage of strong to severe thunderstorms as it will be towards the end of the peak heating cycle. An increasing concern exists for Wednesday into Wednesday Night for urban and poor drainage flooding to flash flooding from showers and non-severe thunderstorms during this timeframe with a marginal risk for severe weather and isolated severe thunderstorms across Rhode Island and Southeast Massachusetts.

SKYWARN Self-Activation will be utilized to monitor activity late Tuesday Afternoon through late Tuesday Night. SKYWARN Activation with Ops at NWS Taunton are possible as we get into Wednesday into Wednesday Night. Another coordination message on Wednesday’s flood potential will be posted by 1130 PM EDT Tuesday Evening.
