Saturday March 11 – There is so much going on from the deep freeze, clocks forward for Daylight Saving Time, the Shamrock 5K in Baltimore Sunday, and the biggest storm of the year off the coast on Tuesday. Once again I have the model projection maps and I have decided to include the snow totals from two models the morning. But I also want to point out that while the number look high, they are already much lower than just a day ago… and I think more adjusting will be needed when the storm track and freezing line get locked in place. That is why I do not give my first call for snowfall until 48 hours before an event. Needless to say, we will have a storm. I have told all of my clients they will be working their plows for the first time this winter… Yes my school clients are on spring break. Murphy’s law for them.
Note: The freeze this morning dropped temps to 22ºF at BWI, about 2 degrees off from the forecast I showed yesterday. That buffer could make a big difference in the snowstorm.
Before I show the maps, here are the headlines:
- Monday Night: Snow begins by or after midnight
- Tuesday Morning: Heaviest snow and closest approach of mix line to I-95
- Tuesday Afternoon/Evening: Storm pulls away, temps below freezing
- Wednesday: Snow showers continue and staying below freezing
This is the best chance to show off your FITF gear again with reason.

This is close to a perfect set up for a major snow storm bordering on a blizzard with winds over 35 mph sustained in the heavy snow. My hesitation is the mix/freezing line very close to I-95. A shift of 50 miles could change the totals for millions between Washington, Baltimore, Annapolis, and Philadelphia. See the totals below
