Schuylkill County Weather Outlook: Stormy Start to September, Better Weekend Ahead

                     Schuylkill Weather Forecast

September will begin with heat, humidity and several opportunities for thunderstorms across Schuylkill County before more comfortable weather arrives for the weekend.

The Big Weather Story

Tuesday through Thursday will be the period to watch.

Temperatures will reach the mid to upper 80s with humid conditions. Several rounds of thunderstorms may develop during that stretch, although no single day is expected to be a complete washout.

The strongest storms could produce damaging winds, frequent lightning and heavy downpours capable of causing localized flooding. The exact timing and location of the storms remain uncertain.

Best Outdoor Weather

Saturday currently looks like the best outdoor day of the week, with mostly sunny skies, lower humidity and afternoon temperatures in the upper 70s.

Sunday also looks favorable, including for the Coalcracker at Big Diamond Speedway, with mostly sunny skies and temperatures in the mid to upper 70s.

Friday Night Football Forecast

Conditions should become less humid by Friday evening for Week 2 of the high school football season.

A stray shower cannot be ruled out, but the widespread storm threat should be lower than during the middle of the week. Temperatures are expected to fall through the 70s during the games.
