Snow in March can be tricky for all sorts of reasons and this possible storm on Friday is one of those tricky storms to track. The European model has been the best model to follow 3-5 days away from a potential and it's the one on many model runs showing a snow event from DC to Portland Maine and inland areas about 50-100miles. This last run today was further south and out to sea. That's not all a big surprise this far out, esp when the storm you are tracking is not even in the lower 48 states yet.
The Canadian model has been steady with a swatch of snow from VA to ME and some could be rather heavy in New England. The GFS has no sense of any storm right now.
The track of the LOW is based off the depth of the COLD high pressure over the Northeast and how fasts it moves east. The colder it gets the more suppressed the storm gets pushed south.
OUR CALL RIGHT NOW
This is a LOW RISK at this point but kinda think of it as that possible last race of the season and that car(storm) is in your rear view mirror. You can't ignore it but it may be the last time you run the winter race this season. We'll be watching every model run and change this week.
