Severe Weather Threat Has Diminished
CHAMPLAIN VALLEY WEATHER DISCUSSION (Update):
     The National Weather Service, Storm Prediction Center in Norman, OK. Has allowed the Severe Thunderstorm watch for 7PM to expire, and cancelled the 10PM watch around 8PM, for our area. Numerous severe thunderstorms occurred this afternoon, mainly south of the Champlain Valley, and Western slopes of the green mountains. The only county in the Champlain Valley that received reports of severe thunderstorm damage was Addison County, with Essex County, New York witnessing large hail, up to 1 inch in diameter, but no reported wind damage. The majority of the severe weather occurred from Southern Essex County, NY to Addison, Washington, and Orange Counties in Vermont, and points south. Some minor flooding was also reported across Chittenden county, with minor flooding likely elsewhere that was not reported. The most susceptible areas for flooding this afternoon were Chittenden, Addison, Franklin, Orleans, and Lamoille Counties in Vermont. Where rainfall rates reached 2 inches per hour, and Doppler radar estimated maximum rainfall totals reached 1.5 - 2.0 inches. A list of storm damage, hail, and flood reports can be found HERE
     For the remainder of the night, additional showers, and perhaps a rumble of thunder can be expected, especially across Northern areas. Additional rainfall totals will range from a tenth to a quarter of an inch. Localized additional amounts to near a half inch could occur with any of the heavier showers. No additional severe weather is expected overnight. Non-thunderstorm related winds should increase into the 10-20MPH range overnight, with gusts up to 35MPH. Some isolated gusts of 40-45MPH could occur, especially across the western slopes of the green mountains, and the higher elevations.
     An updated 7 day forecast should hopefully be up within the next couple of days. Stay tuned!
