Flash flood warnings issued across western Pennsylvania as heavy rainfall hits area
Scattered storms with brief downpours are likely to lead to some flash flooding and flooding on Tuesday in the western Pennsylvania area.
While most were given a little bit of a break from the rain on Monday, the risk for flooding remains high with any thunderstorms today. The National Weather Service has been issuing several flash flood warnings throughout the day.
The National Weather Service also issued a tornado warning for parts of Armstrong and Clarion counties, but it expired around 6:15 p.m.
Flood risk remains in place the next two days
With the atmospheric setup on Tuesday, western Pennsylvania has ample moisture to work with. Instability is high, but not extreme. Steering winds for storms are light, meaning slow-moving and high precipitation-producing storms should be expected.
This setup won't be going away any time soon, with parts of the area under a marginal risk of severe weather on Wednesday and Thursday. Please remember to turn around and don't go through high water.
Humidity levels are in the high range and will remain in the high range through Thursday.
Looking ahead, highs will be in the 80s on Wednesday and Thursday, with the flood risk remaining in place. Unlike Tuesday, Wednesday's rain chance looks highest in the morning hours.
Thursday will see afternoon storms as a cold front sweeps through.
High temperatures move in later
We briefly get some relief from humidity on Friday, but temperatures will be higher on Friday than on Thursday.
Temperatures then turn hot for the rest of the weekend, with highs near 90 Saturday, Sunday, Monday and Tuesday. Heat advisories may be issued next week due to the heat.
