Chance For Severe Storms Thursday





Champlain Valley Weather Discussion:
     The pattern of unsettled weather will continue. We were able to pull off a dry day today, but unfortunately that dry weather will end Thursday. I am sure many of you are not surprised since this has occurred much of the Summer so far.

     Tonight, you can expect temperatures to remain steady or slowly rise, along with a chance of showers, and a rumble of thunder or two. The greatest likelihood for showers will be across Northern New York, and Northern Vermont, where the Warm Air Advection, lift, and moisture will be the strongest. Models indicate that up to a quarter inch of rain could fall along the Canadian border of Northern New York, and Northern Vermont overnight. Current radar trends, and estimates indicate that three tenths to eight tenths of an inch of rain with isolated one inch amounts have fallen along the Canadian side of the St. Lawrence River Valley. So its a good bet that widespread quarter inch of rain will fall across Northern New York, and Vermont. Isolated areas along the Canadian border in Northern New York, could see as much as one inch.

     Come tomorrow, it will be a tough forecast as to whether or not severe storms will occur. The Warm front will have moved through, but with the cold front hot on its heels, there may not be enough time for skies to clear, and the sun to destabilize the atmosphere, especially across Northern New York, and Vermont. However the Storm Prediciton Center out of Norman, Oklahoma, has placed portions of our region in a slight risk for severe storms, along and south of an Orange County, Vermont to Addison County, Vermont to an Essex County, New York line. The primary severe threats would be damaging wind, and some large hail. Things will continue to be monitored closely. Stay tuned for any further updates.
