Major Rainfall Amounts Expected Friday into Saturday, High Flash Flood Risk

Estimated reading time:1 minute, 38 seconds

A coastal storm will bring heavy rain to much of the state beginning Friday Afternoon. Rainfall will then intensify heading into Friday Night, lasting through Saturday Afternoon. Some areas will likely end up with nearly 5″ of rain along the Maryland Border. There may be pockets of over a half foot of rain where persistent banding occurs.

Rain will begin in Southcentral PA around noon Friday, expanding to cover much of the southern half of PA by the evening. It will then become heavier heading into the night especially south of the turnpike. Here is what we expect the radar display by 10 PM Friday Night.

Rainfall rates will exceed 1-1.5″ an hour in our southern counties, while regions such as the Lehigh Valley and the central Susquehanna Valley see persistent light to moderate rain. Locations near the New York Border will be missed for the most part.


Area A – This region will be hit the hardest, as rainfall amounts of 4-5″ are expected. Isolated totals of 6″ will be possible. Flash flooding is nearly guaranteed in flood prone areas.

Area B – This area will be significantly impacted as well, with rainfall amounts of 3-4″ expected. There is a high flash flood risk especially in Southeast PA.

Area C – Locations within this area can expect 2-3″ of rainfall. Flash flooding will be possible, mainly in Southeast PA.

Area D – This area can expect 1-2″ of rainfall. The flash flood risk exists mainly in Northeast PA.

Area E – Rainfall amounts of .25-1″ are anticipated in the area.

Hello, my name is Josh Adams. This year I am a junior in high school in South Central PA. I have had a passion for weather since I was five or six years old, watching the Weather Channel when the average kid my age was watching cartoons. At age 11, I discovered that there is a significant amount of weather info online from knowledgeable meteorologists to weather models and everything in between. I had the privilege to take part in a group that held informational weather discussions nearly everyday. I gained a significant amount of knowledge in several months back in 2012, constantly studying meteorology for hours each and just about every day. I created Northeast Weather Action in early 2013, just after the previous winter had ended. Things were pretty slow to start, however the winter of 2013-2014 greatly helped grow the page. Several of my forecasts verified nicely across the area. I met Chris during that winter in a facebook group, and we talked often about anticipated weather events. Just before the start of the 2014-2015 Winter, I added Chris to Northeast Weather Action (now Pennsylvania Weather Action), and once again we hit several key forecasts. Chris and I are looking forward to giving you the most up to date and reliable forecasts!
