Snow flurries today; week ends colder
Baltimore's western suburbs could see some accumulating snow showers Monday afternoon as frigid air swinging around the deep low-pressure area centered on the Gulf of Maine, and a high over central Canada continues to influence our weather.
Forecasters out at Sterling said flurries and snow showers will be widespread later today, with as much as a half-inch accumulating west of the urban corridor. Snow continues to fall, meanwhile, out in far western Maryland, with Winter Weather Advisories continued through tonight for 2 to 4 inches of additional accumulation in the Alleghenies.
And that's not the half of it. As cold as it's been - and we've had 22 days of below-average temperatures since Dec. 1 - there is another arctic outbreak poised to surge into the Great Plains with more sub-zero temperatures and wind-chills.
And forecasters expect the cold air will eventually spread across the eastern two-thirds of the country, all the way to the Florida peninsula. That will drive our temperatures (after a brief "warmup" at mid-week) back into the 20s for daytime highs by week's end, and deep into the teens at night.
With that cold firmly in place, everybody's watching for the next storm systems to arrive. The first will likely be a relatively light snow-producer, tracking across the country from the Northern Plains to the East Coast with just a few inches of fluffy snow, but sending it deep into the South where snow is scarce, forecasters say.
The second shoe to drop will be a coastal low that's also expected to develop later in the week. How that will connect with the cross-country storm, and whether the coastal storm will charge up the beach or head out to sea, remain in question.
But for now, in this morning's forecast discussion, Sterling's forecasters are saying that conditions expected later this week "favor at least non-negligible chances for precipitation Thursday night and Friday in the forecast area. Expected thermodynamic profiles favor snow."\
