CNY At Increased Risk For Wind And Tornado Hazards
Meteorologists at NOAA NWS Storm Prediction Center has increased the chances for both WIND and TORNADO hazards this afternoon and evening.
A strong low-pressure system is expected to impact the region later today through Friday with very strong winds, heavy rain and thunderstorms.
The Storm Prediction Center says there's an enhanced risk of severe thunderstorms today and tonight. An extensive squall line of strong to severe thunderstorms is expected to develop near and east of the Appalachians from parts of New York to the Carolinas. At least a few tornadoes and scattered to widespread damaging winds are possible.
The severe threat will diminish during the late evening to overnight given an increasing dearth of surface-based instability with east/northeast extent.
The first impact will be the threat for strong to possibly severe
storms and heavy rain later today.
This system will deepen rapidly today and develop into a fast-moving cold front spreading across the region. The cold front should supply enough force for a line of strong convection which will track quickly to the east across PA and s-central NY later this afternoon and evening. The main threat with these storms will be strong/damaging gusts. Could see gusts within this convective line around 40 to 50 mph or higher.
The secondary threat will be heavy rain, leading to flash flooding.
Given the generally saturated soils over certain parts of the area, and the rain from last night...a quick 1-2 inches with locally higher amounts...the threat for flash flooding will be elevated today and tonight. Poor drainage and urban areas have the highest threat, with smaller creeks and streams a close second. The Flood Watch remains unchanged at this time.
We will see very strong sustained west winds. The strongest winds will be over central NY...maximizing out across the lake plain into the wrn Mohawk Valley 30 to 40 mph...gusting 50 to 60 mph. A High Wind Warning has been issued for the nrn Finger Lakes over to Oneida and Madison Counties.
