Today’s slow moving cold front brought plenty of rain to the Delaware Valley. The rain was off and on this morning but became heavy during the afternoon and evening, as expected. Heavy rains fell across the region this evening and prompted flood warnings for urban areas and small streams for the Lehigh Valley and Poconos and flood advisories elsewhere for urban areas and small streams.
A few strong thunderstorms developed this evening across south Jersey cause gusty winds and heavy rains. At least the air temperatures were mild near 60 degrees. So far, 1-2” of rain has fallen across the region with areas of 2”+ in the southern Poconos. The major rivers and creeks are forecast to remain below flood stage but will be on the rise tonight and early tomorrow morning.
The rain will begin to taper off after midnight as the cold front slides through the region. Say goodbye to the mild air mass too. Behind the front, temperatures fall rapidly and the rain will end as a period of snow for the Poconos and possibly the Lehigh Valley.
It is already snowing in areas west of Harrisburg as of 8pm. A winter weather advisory is in effect for the Poconos for a period of freezing rain before changing over to snow before ending before daybreak. A couple inches of snow is possible up in the mountains with several inches in north central PA.
Sunshine returns on Monday with a cooler start to the week with highs in the upper 40s, which is seasonal. We’ll keep it dry and seasonal through Wednesday. Then another large area of low pressure will bring more rain on Thursday, possibly lingering into Friday.
