Forecast: Another Wintry Threat by the Wayside?

By Camden Walker

Tomorrow's accumulation chances small

* InaugurationCast | Later: Top International Weather of 2008 *


Today: Mostly sunny. Increasing clouds late. Near 40. | Tonight: Mostly cloudy. Upper 20s to low 30s. | Tomorrow: Wintry mix to rain. Mid-to-upper 30s. | Sunday: Becoming mostly sunny. Mid 30s. | A Look Ahead


Bitter cold threatens for later next week. But first we have to deal with Saturday, which looks to be yet another wintry mix-to-rain scenario for the metro area. And before that? Just a seasonably cold and mostly sunny Friday to wind down the work week.

Today (Friday): Mostly sunny skies for much of the day. Then increasing clouds by late afternoon. Highs near 40 -- not too shabby for our historically coldest part of winter, right? Still, moderate breezes of 10-15 mph out of the west will chill the air from time to time before dimnishing later in the day. Confidence: High

Tonight: Becoming mostly cloudy. Lows may make it down into the upper 20s to low 30s. But the blanket of clouds will make it difficult for even the cold spots to get colder than that. Confidence: Medium-High

What is the read on wintry weather for Saturday? Read on...

Tomorrow (Saturday): Late morning through evening looks like the timing for precipitation -- possibly starting as a wintry mix of snow, sleet and rain before probably changing to mostly rain -- as a storm system moves through from west to east. The chance of snow and/or sleet briefly accumulating before the change to rain is only about 20% (up that to around 25% north or northwest of town). Highs in the mid-to-upper 30s. Confidence: Low-Medium

Tomorrow Night: Precipitation comes to an end and winds pick up from the northwest toward morning. Lows in the low 30s by dawn. Black ice shouldn't be a big problem except maybe in the far north and northwest suburbs (e.g., Frederick). Confidence: Medium

Sunday: In the wake of Saturday's storm, Sunday should trend mostly sunny but cold. Highs may only reach the mid 30s, and it could be rather windy at least through the morning hours. So bundle up! But don't complain too much -- it may get even colder later next week. Confidence: Medium

Sunday Night: Partly cloudy with temperatures dropping into the mid 20s downtown, low 20s in the burbs. Leesburg and Hagerstown could bottom right about 20. Confidence: Medium-high


Monday should be party sunny. High temperatures will be around average -- in the low 40s. Confidence: Medium-High

Tuesday could be windy, maybe even some snow showers, as the leading edge of even colder air approaches. Highs in the 30s. Confidence: Medium

Midweek next week could bring the coldest air of the season, and maybe another storm threat.

Brrr, anyone else chilled by the 20s this morning? I lost my acclimation!

It's a bone-chilling 24 degrees in New Baltimore. But we had some single digits last month if i recall rightly. will it be that cold next week?

I'm not CWG, so my views are unofficial, but I would say yes, given current model trends, single digits are indeed a possibility, even inside the beltway. We are talking a serious arctic plunge, the type of thing that is a once-per-decade type event. The fact tomorrow's storm is likely to lay down some good snowcover just to our north also makes colder temps a possibility, as cold air maintains its chill better when crossing snow than when crossing bare ground.

Now it could change of course, but that's how things look now. I find it funny none of the traditional outlets show the arctic outbreak much in their forecasts. They show cold but nothing spectacular - low 30s for highs. Probably they don't want to "alarm" people until the event is closer and more certain.

As for snow, the next POSSIBILITY would be, I think, Tuesday, as the arctic front sweeps through (or maybe its a clipper type system?).

Hi weathergrrl - I am uncertain as to your exact location but the airmass we are expecting in about 5 days will likely be the coldest of the season. So, in a way, I would expect all locations in the region to experience (match) the coldest air yet this winter. Bundle up!
