RAINFALL FORECAST: Wind-Driven Rain Likely Friday Followed by Slow Clearing This Weekend

An upper level low slowly moving to our west will be accompanied by a low level jet, and be responsible for a wind-driven heavy rain across our area Friday. Maximum wind gusts will be in the 30 – 50 MPH range, and will occur as the heavy rain moves through. To make matters worse, temperatures will be in the mid 40s to low 50s, so this will be one of the worst weather days of the year.

Expect roughly a nine hour period of heavy rain Friday. Rain will be pushing from south to north. Leftover showers will rotate in on Saturday, so we can’t promise dry Halloween celebrations. Below is Hi-Res NAM Future Simulated Radar for the entire event.

 


FRIDAY – SATURDAY RAINFALL FORECAST

Highest rainfall amounts will be in Central PA, where a stripe of 1 – 2″ is forecast. East of the Susquehanna and west of the Alleghanies can expect between a half inch to an inch of rain. A minor risk of flash flooding will exist in the northern mountains and locations within 20 miles of the Delaware River, since those locations have picked up the most rain recently.

Be sure to share this forecast with family and friends who have Halloween-related plans this weekend!

Josh has been passionate about weather as long as his memory dates! From watching the Weather Channel at age 7, to making hand-drawn hurricane maps at age 11, starting his first weather site at 13, and founding PWA at 15 and forecasting for the state for the past 9 years, Josh's interest in weather has never dwindled! As difficult as it is, he greatly enjoys forecasting for Pennsylvania due to its countless microclimates. The state is an East Coast severe weather hotspot and nearly always home to the rain/snow line during winter storms!
