Strong thunderstorms possible Monday afternoon

Severe thunderstorm, flash flood warnings issued for multiple Western Pa. counties

A severe thunderstorm watch was issued at 1:35 p.m. and is in effect until 9 p.m. Sunday.

A severe thunderstorm watch means that atmospheric conditions are favorable for storms with winds of 60 miles per hour. Flash flooding of creeks, streams and roadways will be possible, especially in areas of poor drainage.

At 716 pm emergency management reported heavy rain due to thunderstorms over northwest Calloway County. After a partly sunny start to the day, it will become mostly cloudy with showers and thunderstorms developing.

Heavy rain does a very efficient job of cooling air as it falls. "The primary risk with any severe thunderstorm will be damaging wind gusts with hail a secondary concern".

This environment is not very favorable for large hail or tornadic storms. Flash flooding is a very risky situation. Plan to take shelter if/when NWS Sterling issues weather warnings.

NWS also advises to avoid driving or walking through flooded areas. The atmospheric conflict will result in chances for severe storms impacting the area beginning anytime after 3 pm this afternoon (Monday). Monday's high temperature is expected to approach 77 degrees, followed by a low of around 65 degrees Monday night. We'll see another chance for an isolated shower on Wednesday as another (weak) front passes through. Weather officials say many flood-prone roads in the county are likely to be impassable Sunday morning.
