Severe thunderstorms expected to impact afternoon commute


The National Weather Service has issued a severe thunderstorm watch for the area, in effect until 11 p.m. on Tuesday.

Sunday: Mostly cloudy, a couple showers and a thunderstorm.

But Saturday's weather put a damper on weekend activities following a string of six 80 degree-plus days that ushered in an active spring after a gloomy April. That combination could translate to several rounds of severe weather for the coming season. Here again we turn to the high resolution model guidance, which is not unanimous.

Torrential rainfall is also occurring with these storms, and may cause localized flooding.

These storms could come with gusty winds in excess of 55 miles per hour, causing downed limbs and power outages.

Most of Upstate south of I-90 could see thunderstorms with damaging winds.

The severe thunderstorms will be near Mifflinburg, Sand Bridge State Park, Alfarata, Forest Hill, Hughesville, Weikert, Snyder-Middleswarth State Park, Troxelville, Lairdsville and Reeds Gap State Park around 2:40.

People are being urged to be aware of the changing weather conditions Monday. Areas north of LI are under a tornado watch. Quarter-size hail might coincide with the strongest storms.

The humid air you experienced Tuesday morning is part of a one-day affair, lasting just long enough to bring in some thunderstorms and showers.
