Champlain Valley Weather Discussion:

OVERVIEW
         Currently a 991mb low pressure center South of Boston continues to strengthen and move North this morning, this low will continue to rapidly intensify down into the 980-984mb range.

RAINFALL
         Rain fall forecasts are the same. There could also be some enhanced heavy rainfall for an extended period of time over the Champlain Valley, as significant Champlain Valley Convergence sets up, with a strong northerly flow. Rain totals across the entire area should range from 1-3 inches, some localized amounts near 4 inches is not completely out of the question at this time. The least amount of rain will be across the St. Lawrence Valley of New York, and the heaviest should be along the spine of the Green mountains. If the heavier amounts are witnessed then flooding will likely be an issue. Right now though only minor/ nuisance flooding is possible. The ground is still fairly saturated from the rains we had in late September.

WIND
         The winds will be strong with sustained winds of 15-30MPH with gusts to 50MPH. Higher winds may occur in the valley with localized gusts to 55MPH.

SNOWFALL
         Snow potential is the same as well, with 2-6 inches of snow expected for the Advisory area, wet snow flakes may still be seen in the Valley if dynamics set up just right. Stay tuned for further updates.
