Forecast: A slippery, wintry end to the year

By Josh Larson

Mix of ice and snow brings slick travel

A somewhat subjective rating of the day's weather, on a scale of 0 to 10.
2A messy mix of snow, ice and rain to end the year? Not my idea of fun. Get tomorrow's 'Digit' on Twitter tonight


Today: A.M. snow and ice, cloudy P.M. 36-40. | Tonight: Cloudy; chance of showers. 33-37. | Tomorrow: Mostly cloudy & blustery. 38-43. | A Look Ahead | Get Express Forecast by E-mail


The last day of the year starts off on a rather unpleasant note: a wintry mix, with the potential for snow, sleet, and freezing rain, is likely through the first half of the day, with less than ideal road conditions possible, especially north and west of town. New Year's Day won't exactly be a winner either: clouds will prevail with blustery winds and highs in the low 40s. While sunshine should return for the weekend into the start of next week, decidedly cold temperatures will stick around -- scarves and gloves recommended.

Today: A winter weather advisory for the immediate metro area suggests a mix of snow, sleet, and freezing rain is possible through the mid-morning hours. North and west of D.C., an inch or so of snow and sleet is possible, whereas in D.C. and south and east, the predominant precipitation type will be freezing rain, which may form a glaze, particularly on untreated surfaces. The steady precipitation will end by mid-morning with temperatures rising above freezing. There is a chance of drizzle after that with highs in the mid-30s (north and west) to near 40 (downtown). Confidence: Medium

Tonight: Unfortunately, low clouds and chilly temperatures are likely to stick with us tonight. A few showers of rain (or even a bit of wet snow, as the night wears on and/or in typically cooler suburbs) are possible as overnight lows settle into the mid- 30s for most of the area. Fortunately roads should not freeze in most spots in the immediate metro area. However, a few slick spots can't be ruled out after midnight in the outlying suburbs -- so use caution. Confidence: Medium

Keep reading for forecast for the opening days of the new year, and please comment with your storm reports...

Tomorrow (Friday): Not the most pleasant or auspicious start to the New Year on Friday, if you ask me. We'll see more clouds than sun and blustery northwesterly winds of 10-20 mph (with occasional gusts to near 30 mph) throughout the day. Afternoon highs will range from the upper 30s to low 40s but the aforementioned wind will make it feel colder. Confidence: Medium

Tomorrow Night: Partly cloudy and continued breezy Friday night, with lows primarily in the low-to-mid-20s. Confidence: Medium


Mostly sunny skies return on Saturday, but will do little to take the edge off afternoon highs only in the low-to-mid 30s with an occasional breeze of 5-10 mph. It will be the type of day that "looks" nice when peering out the window but is colder than you might expect once you get outside. Clear and very cold Saturday night, with lows from the upper teens in places like Reston, VA and Germantown, MD to the low 20s downtown. Confidence: Medium-High

Conditions on Sunday will be quite similar to those we'll experience on Saturday, with the exception of more in the way of cloudiness. I'll call for partly to mostly cloudy skies with still-cold afternoon highs in the low-to-mid 30s and overnight lows ranging from 20-25. Confidence: Medium

We hold onto continued below-normal temperatures on Monday, with partly to mostly sunny skies and highs primarily in the mid-30s. Mostly clear and dry during the overnight hours, with lows ranging from the low 20s in the outlying suburbs to the upper 20s downtown. Confidence: Medium

Freezing rain in NW DC (on top of what appears to be a light coating of snow/sleet), but am hearing reports of up to an inch of snow in NW montgomery and loudoun counties.

I can confirm at least an inch in NE Montgomery. I have not gone outside yet (a bit under the weather), when the sun comes up I'll let you know.

Video of the snow and Greg given a "shout out" from Kim Martucci of WUSA-TV 9.

Here's a surprise.

According to DCRTV, Channel 9 is dropping Kim Martucci as of Jan. 2nd...surprising in that Channel 9 was rather accurate with the Snowpocalypse, while Bob Ryan's low snowfall estimates "bombed" so to speak. Could low Neilsen ratings rather than forecast accuracy have been a factor here???

It will be interesting where Kim ends up. Seems she married recently and they live somewhere in MD. Could a future with some other station [or CWG] be in the cards?

BTW I have temps just above freezing and a sleet/rain mix here.

1.5 inches here in Front Royal. No precip. From the looks of radar, we are in the dry slot so this event is over.

Centreville VA with little/no current precip; 32 degrees. Heard moderate rainfall on the roof after there is lots of slick ice on everything with horizontal surfaces garnished with ice pellets. Lovely.

Bombo47jea -

That's shame regarding Kim. She has been a great addition to a great (IMO, the best) weather team in the area. I was very upset when Tony Pann was dumped as well. I don't understand the moves of the management here...and fankly, I am NOT a fan of Devon Lucie.
I have been a long viewer of WUSA 9, and Topper and the team have consistently remained the most accurate local network team since I remember... There is no legit reason for this, and I will make myself heard by the station.

You guys should really do a better job of predicting wind. 5-10 mph was the prediction today. hmn.
