Third Wave's Close Approach

The third wave of precipitation is approaching the region today in association with low pressure that has developed over the Deep South.  This low will produce a pretty decent snowfall over portions of Virginia and Maryland.  To our south in Delaware and New Jersey, precipitation will not be quite as robust as it will be in Virginia but it should come down steady enough and heavy enough tonight to transition rain over to snow.

Winter Storm Warnings are out for Sussex County in DE, as well as the Eastern Shore of MD.  Winter Weather Advisories are out farther north and northeast, including Atlantic City and Cape May for this afternoon and tonight.

Light rain is already falling across Southern Delaware early this morning.  That will hang out in off and on fashion through the balance of the morning before precipitation picks up from the southwest with the balance of the wave moving in later on today.  Precipitation should increase in coverage after midday from the southwest.

Locally, it does not look like the city gets should miss Philadelphia by and large although a few sprinkles or flurries could graze the southern suburbs up to 295 this evening or tonight.  It will be a close call though and we will keep an eye on things through the day.

Highs will get to just above 40 this afternoon in the city and points south, with southern areas cooling as precipitation moves in.  North of the city should get mainly hang out in the 30's for a high.

We will have an updated discussion on the snow and rain later this morning.
