A few showers Tuesday, heavy rain from Ida arrives Wednesday

Forecast

3 to 6 inches of rain expected area-wide...with locally higher amounts possible

OVERNIGHT: Mostly Cloudy, Muggy, Stray Shower. Lo 70. Winds: Light.

TUESDAY: Mostly Cloudy, A Few PM Showers. Hi 84. Winds: Light.

WEDNESDAY: Heavy Rain, Especially By Evening. Several Inches Of Rain Expected. Hi 73. Winds: SE 10-20 mph.

Other than a stray shower overnight, we should just be mainly cloudy with lows dropping to near 70.

Tuesday will be a cloudy day as we await the remnants of Ida to move northward. With a front stalled nearby, there can be a few showers or even a storm that develops during the afternoon, but most of the day should be dry. By Tuesday night, steady rain will begin to approach from the south, with pockets of moderate to heavy rain possible as early as daybreak Wednesday. It’s still early for specifics, but areas north and west of Harrisburg are under the greatest risk for heavy rain Wednesday morning.

Ida will fuse with the front to bring a period of heavy rain to most of the region Wednesday afternoon and evening. This is when the highest rainfall rates are expected with flash flooding a concern around the evening commute. While not a big concern at the moment, we’ll have to watch areas south of Route 30 for an isolated tornado threat if warmer air can stream north of the Mason-Dixon line. Otherwise, the concern will be for pockets of heavy rain to last into the early overnight before the entire storm moves east of us. When all is said and done, 3-6″ of rain is expected for most places, with locally higher amounts possible under heavier rain-bands. In addition to flash flooding, streams and creeks will be quick to rise Wednesday, with concerns of the Susquehanna rising by Thursday as well.

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.
