Below is the latest on the next winter storm, including our FINAL CALL snow map. We are going with a general 2-6″ across the area. Locations well north of Phila will be in the 4-6″ range, remember while some snow may stick to the roads, most snow will be on the non treated surfaces. In the event the snow does stick to the roads, allow for extra time as the heaviest will be falling during the AM rush. The Winter Weather Advisories are in effect late tonight and Monday morning for eastern PA, most of NJ, northern DE and northeastern MD. A rain or a rain/snow mix will develop overnight and it will changes to snow from NW to SE across the area between 1 AM and 8 AM.A heavy snow is possible 4–8 AM with snowfall rates of 1–2” per hour, resulting in treacherous driving conditions for the Monday morning commute. The greatest travel impacts are expected generally north and west of Philadelphia, especially at higher elevations, where temperatures will be colder and roads most likely to become snow covered. The area will see highs generally in the 40s and the sun coming out Monday afternoon, most, if not all, of the fresh snow should melt by day’s end. Temperatures should stay above freezing for most of the area Monday night as well, preventing a widespread refreeze.

affect how much snow accumulates on roadways, as rates at or

will result in untreated roads becoming slushy to snow covered.
High temperatures Monday afternoon in the 40s will lead to rapid
