A tornado warning was in effect for parts of Allegheny and Washington counties but has since expired. 

Crews are now assessing the damage after the severe weather ripped through the area. The storms and rained cause trouble all over the area, damaging homes, cars and other property. 

 

Storm damage in Washington County caused by straight line winds

KDKA's Failcia Woody was out with the National Weather Service Wednesday afternoon while they conducted their survey of a potential tornado in Washington County.

There were a lot of downed limbs, trees snapped and downed power lines from that line of storms that moved through the area.

While even the radar loops from Tuesday night made it seem like there could be a tornado, the National Weather Service said the damage was caused by straight line winds.

McKeesport house fire

A house in McKeesport caught fire Tuesday from an apparent lightning strike. 

The couple is shaken up but OK after lightning apparently hit the roof of their home, starting a fire inside the attic. 

"It was just a big bang, like an explosion," Marian Pusateri said. "And I thought lightning struck a pole. I didn't think my house was hit."

Pusateri was in the living room and her husband was upstairs when it happened.

"The power went out upstairs," Pusateri said. "My husband was up there. Two bulbs flashed, they fell down. He's running around looking for light bulbs. We didn't even know it was on fire."

They did not know their house was on fire until a neighbor told them. There is smoke and water damage inside the home. 

"We are OK. My dogs are OK," Pusateri said.

Several counties under tornado watch

A tornado watch was issued for Kentucky, Ohio, Pennsylvania and West Virginia. It covers  Butler, Washington, Lawrence, Fayette and Greene counties in the Pittsburgh area.   

A "watch" means you should be prepared. Conditions are favorable for tornadoes to form. If a "warning" is used, that means a tornado was spotted or indicated by the radar and you need to take action.

First Alert Weather Day issued for Tuesday

A First Alert Weather Day is in place for Tuesday because of the chance for severe storms. 

Aware: Showers and rain arrive just around lunch and last through the afternoon.

Alert: It's a First Alert Weather Day with strong to severe thunderstorms developing after 4 p.m. and lasting through around 10 p.m. There's the possibility for damaging winds and an isolated tornado is possible. A Tornado Watch is in effect for several counties until 9 p.m.

Tuesday temperatures will be mild with highs approaching 70 amid warm and moist airflow. Showers and rain move in through the afternoon with a trailing cold front arriving late this afternoon. That sets the stage for another round of strong storms with our area in the slight risk category from the Storm Prediction Center. 

Storms that reach severe levels will have the biggest threat of causing damaging wind and we can't rule out a chance of an isolated tornado. The timing of the severe weather will be mainly between 4 to 10 p.m. 

After the cold front passes, skies will gradually clear with a sprinkle around in the wee hours of Wednesday morning. Otherwise, we'll look for some drier air to arrive through the day Wednesday and more dry time on Thursday.

Showers return at times Friday and Saturday but Sunday looks dry and pleasant for Mother's Day. Temperatures all week stay seasonable in the 60s.
