PITTSBURGH (KDKA) — Another round of storms is moving into the area, but the good news is this wet weather is expected to usher in cooler, less humid air behind it.
The National Weather Service has been issued for Allegheny, Beaver, Butler and Washington counties through 6:15 p.m.
A Severe Thunderstorm Watch is in effect for Allegheny, Armstrong, Beaver, Butler, Clarion, Crawford, Erie, Fayette, Forest, Greene, Indiana, Jefferson, Lawrence, Mercer, Venango, Washington and Westmoreland counties through 10 p.m.
“Heavy downpours, frequent lightning and briefly gusty winds are all a concern with small hail also possible,” said KDKA Chief Meteorologist Jeff Verszyla.
He says the scattered showers and thunderstorms will be crossing the area this evening.
“We’ll see an increase in clouds as showers and thunderstorms cross the area this evening. They’ll be moving out of the area before midnight tonight, and then at wake up [Wednesday] morning, we’ll see temperatures cooling off nicely into the low 60s, 70 at the lunch hour,” said Verszyla. “Nice mixture of clouds and sunshine [Wednesday], and in the afternoon, our highs will be in the mid-70s with much lower levels of humidity.”
He says the reason for the change is an approaching cold front.
“Sparking off the scattered showers and storms from Pittsburgh on to the north and west up toward Cleveland,” Verszyla said. “The actual front is now approaching the Cleveland area, should be moving through here at about midnight tonight or shortly after, it sinks south [Wednesday]. Northwesterly flow kicks in behind it, much drier air, lower dew point air moves in along with high pressure setting us up nicely the remainder of the work week.”
Mostly sunny skies and pleasant conditions are expected Thursday with a high of 78 degrees.
