Higher heat index returns today before Sunday cooling which will include elevated severe storm risk level

EARLY ALERT: This is the final day of the current heat wave but a changeover to cooler temperatures will bring an elevated chance of severe thunderstorms Sunday, with a forecast that “an isolated tornado cannot be ruled out.”

The National Weather Service (NWS) at Buffalo assessment, based on the maps from the NWS Storm Prediction Center (SPC) which accompany this story, reports scattered thunderstorms this afternoon and tomorrow, with some of those Sunday becoming “severe with damaging winds as the main threat,” with the NWS Weather Prediction Center saying there also is a Marginal Risk tomorrow for excessive rain.

The Slight Risk category Sunday is at a two-out-of-five level on the severe weather chart, with potential for a tornado being at under five percent.

It is noted that severe storms experienced this week in Allegany County were forecast in the Slight or lower Marginal Risk levels.

A HEAT ADVISORY continues until 8PM today in Steuben County east and Northern Pennsylvania, including neighboring Potter and McKean counties due to even higher temperatures than the high temperatures and oppressive humidity expected to be experienced in Allegany, with a Marginal Risk of severe weather today in the eastern half of Steuben County east.
