FLASH FLOOD WATCH IN EFFECT UNTIL 5AM THURSDAY MORNING (Click HERE For Details)


Champlain Valley Weather Discussion:
     The National Weather Service in Burlington, Vermont has issued a Flash Flood Watch for all of Vermont, and portions of Eastern New York, for the potential of 1-2 inches of rain, with localized higher amounts. Click on the above red link to view the alert details.

     Things continue to look interesting as far as the Flash Flood Threat is concerned, however the Severe Thunderstorm threat, seems to be slowly diminishing.

     National Weather Service Doppler Radar is indicating numerous showers and thunderstorms developing across much of Vermont. These showers and thunderstorms have been training/ back building in some areas, and Doppler radar indicates that in excess of 3 inches of rain has fallen across Northwestern Rutland County. A Flood Advisory has been issued for that area. Rain will continue to overspread much of the area for the rest of the evening, and moderate to occasionally heavy rain will continue into the early overnight hours before tapering off to showers. The heaviest rain should occur across the southern half of Vermont. Widespread rainfall totals are still expected to range from .75" - 1.5" inches, with very localized areas seeing 4-6 inches of rain. My flash flood watch will remain in effect.

     The Severe Thunderstorm threat seems to be diminishing. But still across Northern and Central Vermont, as Well as Northern New York, CAPE values remain in the 1500-2000j/kg range, with Lifted index's in the -4 to -6 range. The strongest storms at this time appear to be across Northwestern Vermont, and Northeastern New York. Strong to possibly severe thunderstorms will remain possibly across this area for at least a few more hours. My Severe Thunderstorm Watch will remain in effect until 8PM. Stay tuned to this developing situation.
