Just over 100 electric subscribers were without power this morning in Allegany County after another train-like effect of severe thunderstorms moved from southwest to northeast late last night, resulting in torrential downpours, wind and hail, and also spawning a Flash Flood Warning in the northeastern part of the county.

The risk of severe weather increases today from Marginal to Slight (second level on a scale of five) for Allegany and all or parts of surrounding counties, according to forecasts from the National Weather Service (NWS) Storm Prediction Center (SPC) in Norman, Okla. The risk of hail will increase into the Marginal level (a five to fourteen percent chance).

Storms during the past three days all have occurred under the Marginal Risk category.

At the same time, there is a Marginal Risk of excessive rain again today for a similar geography, being repeated for Southern Allegany County and neighboring Pennsylvania areas Friday, and for the entire region again on Sunday, according to the NWS Weather Prediction Center (WPC) in College Park, Md.

At 6AM Thursday, 105 Rochester Gas and Electric (RGE) customers were listed without power, presumably due to last night’s storms, with 49 in Allen, which includes Angelica and Fillmore addresses, 42 in Angelica, and 14 in Bolivar. There were another 303 New York State Electric and Gas outages in Eastern Steuben County, including a few with Allegany County addresses.

Additional weather-related information for the next few days include:

— A HEAT ADVISORY remains in effect for Western and some Central New York counties to the east until 8PM today. The weather alert won’t expire for many Central New York counties until 8PM Friday, and will continue for bordering Potter and McKean counties in Pennsylvania and beyond until 8PM Saturday.

— Despite expiration of the advisory, maximum heat indexes in Central Allegany County, are forecast to hug just under 90 degrees through Saturday, together with humidity continuing at or just above the “oppressive” level of 70.

— Although Meteorological Summer (June 1 through August 31) already has been underway for nearly three weeks, Astronomical Summer will begin at 4:51 this afternoon, with the arrival of the Summer Solstice when the Northern Hemisphere experiences the longest period of sunlight, or the longest day of the year. Sunset in Central Allegany County will occur at 8:52PM.
