Parts Of Area Under Flash Flood Watch
PITTSBURGH (KDKA) — A Flash Flood Watch has been issued for parts of the area as another round of showers and thunderstorms move through tonight and into the morning.
The watch is in effect for Allegheny, Greene, Somerset and Washington counties through Monday morning.
Forecasters say heavy rainfall over the past several days has greatly increased the soil moisture. As a result, showers and scattered thunderstorms with heavy downpours tonight could cause flash flooding.
“It looks like it could get a little noisy a little later on tonight with some flashing lightning around here, a little thunder going on,” said KDKA meteorologist Dennis Bowman. “So, just be prepared to listen to that later on tonight here in Western Pennsylvania and points nearby.”
Residents along streams and creeks should remain alert for rapidly rising streams where heavy rain persists.
Also under a watch are Garrett County in Maryland, and Brooke, Marshall, Monongalia, Ohio and Preston counties in West Virginia.
Bowman says today’s high got up to 81, and Monday we can expect to see temperatures in the lower 80s.
“Trying to time the occurrence of a shower or a thunderstorm over the next few days is going to be an impossibility,” said Bowman. “You just have to know that that chance is there as you go along.”
Then, the high will climb to the upper 80s on Tuesday and Wednesday.
“We thin out the rain [Monday] morning, and then it kind of gets reinforced and billows back in as we go into the second half of the day,” Bowman added. “Nudging north is a warm front, keeping us in the warm muggy air mass. The problem is it just doesn’t wander away. Then, late in the week, a cold front is going to come in; so we’ve got daily chances of storms and a couple of them could be strong from time to time.”
