An area of low pressure is sliding south of our region this evening. The result is bursts of sleet, wet snow, and rain. Some charge separation is taking place resulting in thunderstorms. In some areas, the precipitation rates have caused localized cooling to occur with temperatures flirting with the freezing mark. Temperatures should remain fairly steady and may drop a degree or two later tonight. But some icy spots are possible Sunday Morning. Reports have come in of sleet and wet snow accumulation (even sleet accumulation in parts of South Jersey) and this is creating some travel difficulties.
For Sunday, we will see a brief break before more precipitation arrives late Sunday Night and early on Monday Morning with a warm front. Another round of wet snow, sleet, and rain is possible early on Monday Morning and depending on the arrival and intensity, some accumulation cannot be ruled out. By midday on Monday, much of the region should see plain rain with a mix hanging on closer to the Poconos. Monday Night into Tuesday Morning should be the heaviest rain as a cold/occluded front heads in our direction with a wave of low pressure across the Great Lakes driving this front eastward as a new wave of low pressure develops over or just south of the region.
Some mid-level spokes of energy could create rain showers or flurries Tuesday Night, Wednesday and Thursday. However, it does appear modest clearing begins to occur late on Tuesday with at least some breaks in the clouds.
Happy St. Patrick's Day!
