Slow moving areas of rain tonight


Heat and humidity stick around through much of the weekend...

TONIGHT: Scattered Slow-moving Downpours/Storms. Lo 71F.

MONDAY: Partly To Cloudy, A Stray PM Shower. High 82F.

TUESDAY: Mostly Sunny, Seasonable and Dry. High 88F.

Another day near 90° and high humidity levels may lead to more slow-moving downpours and storms locally. We are watching an area of slow-moving rain that has been stalling over the Midstate since late Sunday evening. A Flash Flood Watch remains in effect for Franklin, Adams, Perry, Juniata, Mifflin, York, and Cumberland Counties through tonight. Rain totals could quickly exceed one inch (as high as 2-3 inches for isolated areas), and we will have to watch for areas of high rising water on local creeks and even streets that can’t keep up with the influx of rain.

An east/northeast wind Monday will keep clouds around for much of the day. Weak ripples in the flow combined with some low-level moisture can spark a stray afternoon shower, but most places are expected to remain dry to start the week. Humidity will slowly decline throughout the afternoon to almost comfortable levels by Monday night and Tuesday morning.

Tuesday and Wednesday look to be stellar summer days as the sun breaks out and humidity remains at bearable levels. We will warm into the upper 80s by Wednesday afternoon ahead of our next front. This front will lead to our next chance of showers and storms by late Thursday. There are some indications that this front may slow and/or interact with some tropical moisture which may keep the threat for showers going into Friday. This is something we’ll watch closely.
