Good Monday morning NWS Mt Holly FB friends and visitors to NJ DE e PA e MD. Showers should arrive late this morning or afternoon. Dense fog is possible tonight. A huge warmup is expected Tue-Wed with record breaking warmth, especially Wednesday when forecast highs in the mid 70s...should be within 4 degrees of the all time February highest record. Then it chills Thursday with a period rain (possibly briefly mxg with sleet/frzg rain ne PA high terrain) . Seems like a better chance of icing Friday morning near and north of I-80. Overall, periods of rain Thursday-Sunday should bring us 1-2 inches, probably propelling Atlantic City to all time Feb wettest record and probably pushing Philly and Wilmington into the top 10 wettest February in our 100+ years of record keeping.

Here's the latest snowfall total map. Some impressive amts thru the Lehigh Valley into Nrn NJ. We can see the snow cover shrinking each hr as the sun shines brightly across the area. Warm wx is on the way. Any remaining snow will disappear pretty quickly! #njwx #pawx #dewx #mdwx

Good Thursday Morning! A few days of warm weather, then turning much colder Friday night through Saturday. A quick moving storm will bring wintry precipitation to much of our area from late Saturday afternoon into very early Sunday morning.

The snowfall map below is our first take regarding the late Saturday into early Sunday system. The amounts will be highly dependent on air temperatures, precipitation intensity and ground temperatures. There should be an area with some mixed precipitation and even rain which would cut down on snow amounts. While we are expecting an area of accumulating snow, the amounts and impacts are less certain. Another update will be issued later today.

An active weather pattern continues as we are watching two systems. The first brings rain Thursday night and Friday. More uncertainty is present with the second one Saturday night with rain and/or snow.
