A cold air mass will move down from Canada for the weekend. At the same time, a storm system approaches from the South. Computer models seem to be having a better handle on this, and will continue to do so as the storm organizes more before it heads up the East coast.
More model updates throughout the weekend will give a clearer picture on the timing and precipitation type, as well as snow amounts (yes: we expect accumulating snow through part of the area). As of now, snow could move in as early as Sunday morning for part of the area, and through the afternoon and night.
Saturday: mostly sunny – partly cloudy. Highs around 47 degrees
Saturday night: Lows around freezing with the storm approaching
Sunday: Could see snow by the morning, certainly by noon. Timing may change though as we get closer. Cold enough for all snow north and west, mix to snow in Philadelphia, then rain to snow or a mix in New Jersey and Delaware.
Sunday night: Snow continuing, with a better chance for any precipitation to change to snow in New Jersey and Delaware. Tapering off overnight as of now. . . Temps below freezing overnight.
Monday morning: Icy spots on roads, some roads could still be snow-covered from Sunday night. Depending on the timing of the storm, some snow could still be falling early Monday morning. TBD.
How Much Could Fall?
Accumulations will be higher north and west maybe a few inches or more (as of now), with less as you go farther south and east because of higher rain chances and a mix. But of course if the timing changes, then that would directly impact snow totals. So this will have to be watched very closely.
- North & West: 3-5 inches
- I-95 corridor: 1-3 inches
- South & East: Less than an inch
Snow should melt at the start, but then as temperatures drop below freezing later Sunday night, snow will stick to roads. Expect more of a “wet” snow with higher water content.
