On Wednesday afternoon the National Weather Service issued a Hazardous Weather Outlook that stated the following:
Severe thunderstorms with damaging winds 60 mph or greater, large hail exceeding 1 inch in diameter, and locally heavy rain of over one inch in less than one hour is possible this afternoon and evening. An isolated weak and short-lived tornado is also possible.
Schuylkill County was included in this alert but not included in a Flash Flood Watch that was issued for counties just to the west like Berks, Carbon and Lehigh. That doesn't mean Schuylkill would not see any bad weather.
A line of storms is expected to develop Wednesday afternoon and cross Schuylkill county between 6:00pm and 7:00pm.
These storms shouldn't necessarily change your plans but you'll want to keep an eye on the sky.
