East Central PA Forecast

Basic CMYK

Proud Sponsor of the East Central PA Forecast Region


Our east central PA forecast region includes Allentown, Hamburg, Reading, Lebanon, Harrisburg, Pottsville & surrounding areas. Forecasts are updated daily M-F and Saturday that covers both weekend days – not Sunday. 


Occasional showers possible through first half of Saturday, fair and warm summer day Sunday…

The 4th of July forecast: Model guidance struggled with the 4th forecast for the past few days. Clouds and a few showers will be present through at least the morning hours on Saturday, and becoming more isolated 12-3pm. We are optimistic for partial clearing later in the afternoon and evening. Fireworks shows after sunset should not be affected and should go on as scheduled. Temperatures will be held in the mid 70s with the clouds/showers expected for two-thirds of the daylight hours.

Sunday and Monday remain dry with an increase in temps and humidity. Listed isolated chances for a PM thunderstorm Tuesday, but will watch for more clouds than sun that may affect temps – for now listed partly cloudy with the uncertainty. A more scattered shower/thunderstorm threat is possible Wednesday afternoon/evening with a cold front moving through the region. It is still uncertain strength of storms, and will re-examine earlier in the week as we get closer. Thursday we followed the GFS depiction of a partly cloudy lower humidity day despite the European model indicating more thunderstorms with an MCS.
