The combination of a front stalled closed to the region combined with a flow of tropical air from the south will continue to set the stage for heavy rain across parts of the region. A flash flood watch remains in effect for the counties along and east of I-99 through the day on Wednesday. This means there is a potential for flooding to occur in a very short period of time. In addition, a flood warning is in effect for Aughwick Creek in Huntingdon County until Thursday. The river will rise above flood stage tonight will crest in the early morning hours on Wednesday.
We’ll have scattered showers and thunderstorms tonight, especially near and east of I-99 where some can bring flooding downpours. It will remain rather cloudy and humid with areas of fog. Temperatures will not drop much with lows in the 60s. Tuesday will remain rather cloudy with showers and thunderstorms that will be more numerous during the afternoon and near and east of I-99. Any of these can once again bring flooding downpours. With the clouds and precipitation temperatures will not rise much and will stay in the 70s. Wednesday will also feature more clouds than sunshine along with scattered showers and thunderstorms, any of which can still be heavy. Highs will be in the 70s. A front will move through the area later Wednesday and that will help to dry us up a little of the end of the week. Thursday will be warm and a bit humid with a mix of clouds and sunshine and highs near to just above 80. Another weak front may bring a pop-up shower or thunderstorm on Friday; otherwise, we’ll have a mix of clouds and sunshine with highs in the 70s to near 80. Behind that front, Saturday will likely be partly sunny and rain-free. There will only be a small chance for a shower or thunderstorm on Sunday. Highs each day over the weekend will be in the 70s to near 80. We’ll have a better chance for some showers and thunderstorms on Monday.
