         The National Weather Service in Albany, NY continues the Flood Watch for Bennington, and Windham Counties in Vermont for 2-6 inches of rain with locally higher amounts possible by early Friday morning. A High Wind Warning is also in effect for the potential of damaging wind gusts up to 60MPH, with localized gusts in excess of 60MPH.

         Champlain Valley Weather continues a Wind Advisory for All of Vermont, and portions of Northeastern New York, for sustained winds of 15-30MPH with gusts to 50MPH. Winds will increase later this evening, and tapper off by Friday mid-morning. Depending on the overall strength and track of the system, winds could potential be stronger and a High Wind Warning may be needed with short notice. A Flood Watch also continues for all of Northern New York, and Vermont for the potential of 2-4 inches of rain with isolated amounts exceeding 4 inches. Stay tuned for further updates.

Champlain Valley Weather Discussion:
         Just an update, everything appears to be on track. Still concerned with rainfall totals, some models are indicating 1-3 inches some 2-4 inches, and some 3-5+ inches. At this point I will stick with the 2-4. The best chance at seeing in excess of 4 inches of rain will be across the Adirondacks of Northern New York, and across Southern, and portions of Eastern Vermont. Already as little as a quarter inch to as much as 2 inches of rain has fallen across the area, with the lowest amounts in the St. Lawrence and Champlain Valley's, and the highest amounts across Southeastern Vermont. For the rest of today the heaviest rain should be over Northern New York, and the heavy rain threat will shift back into Vermont into this evening and overnight.

         As far as winds go, the surface has been extremely stable, and winds have been calm almost the entire day. Winds are going to highly dependent on the ultimate track of the low pressure center, and whether or not we can get the warm front to move over our area. If the warm front moves overhead, then the surface will become more unstable allowing for stronger winds. Right now, we will have to wait and see what happens, but I am fairly confident that we will see some stronger wind gusts, especially in the higher elevations. A High Wind Warning still may be needed upon short notice overnight, especially for areas in Southern Vermont. Please stay tuned for further updates on this developing weather situation.
