There are some flurries on Doppler Radar as another push of strong winds is holding the cold air in place. High temperatures today are more typical of January and will be joined by wind gusts over 30 mph. The wind should ease over the weekend for St. Patricks Day, but if you want to talk luck of the Irish… Snowshoe, WV has had 68 inches of snow in 8 days. The epic March has at least one more Nor’easter up its sleeve. Now that we are within 4 days event we have a better handle on how this may develop. There are still some details left to be sorted out, but plan for messy wintry mix across the region Tuesday and Wednesday. See the latest below.

High Temperatures

Thanks to the winds it will feel like the upper 20s to lower 30s


Saturday Showers

There will be a band of light snow/rain riding a jet streak into central Maryland. At this time it looks like it will miss southern PA, but metro areas could get a little damp during the day.


Storm Contrast (Tuesday/Wednesday)

See the animations below

Here are the GFS and Canadian Models for comparison. These are the two I locked in on to show all week.  Please keep in mind, to get accumulations in March, we need snow to fall overnight, or be very heavy during the day to battle the stronger March sun.

These both now show rain moving in Tuesday with snow in the colder northern suburbs. Let’s leave it at that for simplicity now. We can fine tune the snow line as we get closer. Snow will spread across central Maryland Tuesday night. But

GFS: Slows the transfer of energy to the coast until Wednesday. This results in more snow.

Canadian: Faster jump to the coast on Tuesday, so the storm departs faster by Wednesday morning.

The European Model not shown here shows an all out snow event for all of central Mayland and north. That includes very high snow totals. I can not support that solution at this time.

Note: I WILL NOT show snow forecast maps until within 72 hours of an event. That will be this weekend when I being.  I show my snow forecasts starting 48 hours from the event. That is when there is more confidence and less likely to waver back and forth.
