Severe weather potential today in Allegany County, increasing to the south and east

BREAKING: The Southern Tier of New York, including much of Allegany County, and Northern Pennsylvania are under threat of severe weather today, increasing significantly as one travels south and southeast.

The National Weather Service (NWS) at Buffalo says a fast moving low pressure system will cross the region today, moving from northwest to southeast, resulting in potential for rain, thunderstorms, and gusty winds, along with possible hail in the southernmost parts of Allegany and adjoining counties and increasing risks for tornadoes as one moves into Pennsylvania.

Maps accompanying this story, from the NWS Storm Prediction Center, show current risk forecast areas, although it is noted that any line can vary by as much as 25 miles, or over half the length of Allegany County.

Arrival times for the storms, depending on location, are projected for before noon today and continuing until late afternoon before dissipating in the evening hours.

Forecasters say that following this system, high pressure will build in tonight and bring a return to drier weather that will last through Tuesday. Unsettled weather returns by midweek when a Marginal Risk of excessive rain is possible.
