Near 70 degrees to snow within 2 days

Near 70 degrees to snow within 2 days

Thursday February 15 2018

Warm air is already building in this morning and it will be the warmest we have felt in months. Some of the region is starting off with showers and fog, but we will get many dry hours and sun to boost the day ahead. Computer modeling has a hard time adjusting the such an anomaly as temperatures will be about 25 degrees above normal. So it is possible that while we show upper 60s to near 70ºF, many end up on the top end of that… except if you are near the chilly Chesapeake Bay.  Note, this is not even close to the record high today.

Rain begins to arrive tonight and temperatures will tank tomorrow, so highs will be in the morning. Then we set up a unique situation where the arctic front drops south, then returns Saturday with just enough cold air in place to produce a wet snow. That means snow from colder clouds with high water content, but the warm ground and surface temperatures will inhibit stickage until overnight. That will eat into potential snow totals. See more below.
