Drenching thunderstorms with winds projected for Saturday, with localized flooding possible

EARLY ALERT: A Slight Risk of severe thunderstorms, with a lesser Marginal Risk for excessive rain and localized flooding, is expected for the Allegany County area Saturday, after pleasant weather today.

The National Weather Service (NWS) Storm Prediction Center (SPC) is projecting the second level on a scale of five risk tomorrow for severe thunderstorms, primarily wind but with a small chance for hail and tornadoes, while the NWS Weather Prediction Center (WPC) is forecasting the lesser Marginal Risk for excessive rain, increasing to the southwest in Pennsylvania.

Areas outlined on the maps accompanying this report, however, can vary by as much as 25 miles.

The NWS at Buffalo is reporting the possibility of localized rainfall exceeding more than two inches of precipitation in some areas.

Forecasters say that sunshine mixing with high clouds today will result in temperatures with highs mostly in the mid-70s to low-80s and comfortable humidity levels.

This all will change tomorrow, however, with much more humidity and unsettled weather as storms move through and to the east on Sunday.

It is noted that the two risk levels are those forecast for significant storms occurring during the past 10 days.
