3/7 DC/MD/VA Weather Outlook


Pattern will get cold after the second day of warmer weather. Strong signs that the pattern will turn Spring Like in about a week! There are possibilities of snow between now and then but nothing set in stone!

Where are we headed? It appears that in about 1 week we will see the Polar Vortex (a strong low in Canada that is cold) split and/or retrograde westward and lift out. This should allow the Southeast Ridge to build. Net result, a warming trend. This is a bit questionable based on some models, but I felt the first good chance of spring coming. Until then, the polar vortex will have several spokes of energy and the possibility one of these could link with ejecting energy off the Southwestern United states. If phasing were to occur, it would be interesting to see if wintry weather could overtake the region again.

Summary: A front will approach the region. Overnight rain will occur and there are signs of secondary development along the front. If this were to occur just right, eastern areas may see a dose of snow tomorrow. I am not too sure about it, and, unfortunately this may take an almost now cast to catch exactly what happens. The low will likely form along eth front, but the westward ability for snow **SHOULD** be limited and thus just scattered snow and rain showers tomorrow. Tonight, as the front moves through a few thunderstorms could be possible. If not Thunder maybe some convective rain showers with gusty winds. Very windy conditions should set up tomorrow with dropping temperatures. We will then have a day before a potential clipper system Thursday Night and POSSIBLY a bigger southern stream system this Friday into Saturday. Both of these have potential for a mix or rain and snow, or even snow on the Friday into Saturday event. As noted above
