THIS EVENING: Scattered Showers, A Storm. Temperatures Drop Into the 70s. Winds: Light.
OVERNIGHT: Steady Rain Develops. Lo 70. Winds: Light.
WEDNESDAY: Heavy Rain From Ida. 2-4″ South, 4-8″ North. Flash Flooding. Hi 70. Winds: NE 5-15 mph.
There have been some showers and storms west of the region today, with flash flooding already occurring around the Pittsburgh area. Some showers will roll into our area this evening, but shouldn’t cause too many issues as the remnants of Ida remains well south of us. Steady rain though will move in after midnight, first over areas south of the turnpike and then spreading north.
Ida will fuse with the stalled front to bring heavy, flooding rainfall to most of the region Wednesday through Wednesday night. The first round of rain will come ahead of the warm front Wednesday morning, which could be heavy at times. The axis of rain will then lift north, potentially allowing for a lull south of the turnpike while places north of Harrisburg continue to see steady rain. The heaviest rain will arrive for everybody by late-afternoon as the center of Ida moves in. This is when flash flooding is most likely, along with the potential for isolated tornadoes south of Route 30 where some warmer air may sneak in by late-day. The heaviest rain and storms should exit our eastern counties by 10p, although rises in streams and river levels are expected to continue through Thursday.
The good news is that beyond Wednesday, the weather quiets down drastically. Drier and much less humid air will move in for late-week, with highs in the 70s for Thursday and Friday. We warm back up to near seasonable levels early next week.
