Periods of rain, cooler for Saturday

TONIGHT: Increasing Clouds. Lo 66.

SATURDAY: Cloudy, Breezy, Scattered Showers Starting Around Noon. Heavier Rain by Evening. Hi 74. Winds: E 10-15 mph.

SUNDAY: AM Leftover Showers, Evening Scattered Downpours/T-Storms, Humid. Hi 82.

The evening stays quiet and dry with temperatures in the 80s. More clouds do roll in overnight and temperatures drop to the mid-60s. We likely wake up tomorrow to more clouds as rain begins to head our way from the south.

Saturday looks cloudy, cooler, and damp as a coastal system heads north up the eastern seaboard. A breeze from the coast will bring scattered showers, starting in the late morning and early afternoon lasting through the night. This storm will likely bring heavy rain, some models show locally high rain todays of 2 inches or more. Highs tomorrow will be in the 70s, but could get stuck in the 60s thanks to the east winds and rain. The heaviest rain looks to arrive by Saturday evening into early Sunday morning.

By Sunday, the humidity will ramp up and it will be a very tropical-like day outside. Some lingering showers from the coastal storm are possible during the morning. Then the midday hours should be drier as more warmth and humidity build. Downpours and storms then form during the evening with highs in the lower 80s.

After the coastal low departs early Sunday, Central PA enters "The Convergence Zone". There will be another low off to the west in the Ohio Valley that will stall out through next week. High pressure will move into the Atlantic and stall out off the east coast. The high will bring Atlantic moisture inland, while the stalled low to the west will help push Gulf moisture northward. Central PA will be right in between and the convergence from both system will provide daily rainfall chances through next week. Downpours and storms will be common locally and could lead to flash flooding concerns from Sunday onward. The weekend storm will likely bring over one inch of rain alone before we even get to next week.

This is a bit of an unusual weather pattern for July, so stay tuned and we will keep you update as we get new data each time and several times each day. The forecast will be critical over the coming period to stay ahead of the rain. Try to enjoy today...and the weekend!
