Update: Light Rain and Patchy Ice Settle In

By Capital Weather Gang

Late-day travel could be tricky for far north & west burbs

Winter Weather Advisory in effect through 9 a.m. tomorrow N&W of D.C. (includes Loudoun, Montgomery, Howard and Fauquier counties and points N&W)

Right Now: The morning has come and gone with few problems in the immediate metro area, as expected. Precipitation has been spotty and intermittent, and locally has been mostly in the form of plain rain, with temperatures mainly between 32-34 degrees. The far north and west suburbs (Loudoun, Frederick and Fauquier counties) have seen patchy sleet and freezing rain, with temperatures right at or just below freezing.

This Afternoon & Tonight: The time and place to watch will be this afternoon/evening's commute home, primarily along and to the north and west of a line from Gaithersburg, Md. to Leesburg, Va., where the combination of some heavier precipitation (sleet and freezing rain), loss of daylight, and temperatures possibly sinking a degree or two could make for some tricky travel conditions.

That's not to say that some slick spots won't form in the closer-in north and west suburbs during the late afternoon and evening. But widespread icing is not expected for the immediate metro area, where plain rain may end up being the predominant precipitation type.

Overnight, temperatures rise a little, into the mid 30s, and precipitation turns to plain rain area-wide. In fact, quite a bit of rain could fall late tonight through midday tomorrow, before tapering in the afternoon.

See Matt Rogers' forecast for tomorrow through the weekend.

Any thoughts on the setup for next Tuesday?

It figures...the first Clarendon Ballroom dance of the New Year...and we get this boring old PLAIN RAIN with threats of wintry mix/icing!!!

Last time we had an ice storm for a C.B. swing dance [remember the INFAMOUS Mixing Bowl fiasco last February!!!] they DID NOT CANCEL the dance ... and only around 40 of us hard-core swing dancers showed up. Expect no cancellation tonight, but a few "melted-down" swing dancers.

Weather tidbits...tornado warning just expired in SW Mississippi.

Hi,

On a day like this where a few degrees can make a BIG difference it occurs to me to question how accurate the temperature reported by the typical "consumer/commercial" weather station installation is - not so much the equipment itself which at least for temperature is probably pretty good - but the impact of location, surrounding buildings, wind, etc.. OR is the variation that we see down to micro climate fluctuations ?

For example I am looking at a weatherbug station at Lakelands MS giving me 28.8 F while less than a mile away QO is at 31.2 and NIST is at 32

SO, it seems pretty depressing hearing everyone's comments over the past week or so about the shift in the NAO and the resultant negative (for snow lovers) impact on this winter's weather. Does this mean that overall, the CWG forecast for a fairly average snowfall winter is no longer the consensus? How do the rest of you more experienced commenters feel? No snow? Is it over already? AJim?

@manassasmissy

A large percentage of our snow usually falls between mid-January and late February. There's no reason (yet) to think this year will be any different. We should get some snow.

@bdeco

The event next Tuesday looks interesting. Too early to speculate about details, but a wintry mix seems like a reasonable early guess...

@mdScot

You raise a good point about these weather stations. Are they sited properly? How well are they calibrated? It probably varies. That's why you need to look at a group of stations in an area collectively rather than relying on a single one.

Tuesday does look interesting! Right now anyway, We all know what happens to these "interesting" events has they closer in range. So IMO don't get excited yet. By this weekend, the details will become much more clear. Based on the pattern and trends, IMO its either going to be mix precip or rain.

And today looked interesting last Tuesday, too.

It sounds pretty bad to the north and west per this NBC 25 report ("too many accidents to count"): http://your4state.com/content/fulltext/?cid=45701

They are saying 1/4 inch ice possible.

NBC25 is based in Hagerstown.
