Mike Thomas has the FOX v Weather forecast for Friday, March xi
Friday will actually be a squeamish jump say with sunshine and temperatures reaching the lower 60s, but winter volition brainstorm to make its return after the midnight hr tonight.
Rain shower are probable to first overspreading the region eastward of the I-81 after the midnight hr this night. Temperatures will likely exist in the upper 40s and lower 50s around the region, so all rain is expected at onset.
Rain will intensify as a storm system to our south begins to strengthen and push northwards towards our beaches. Sat'due south high temperatures will exist set before the dominicus ever comes up.
By the sunrise hours, temperatures start taking their tumble. The timing of this cool down will be absolutely key for how fast rain transitions over to a menstruation of snowfall, but near atmospheric condition guidance suggest it is likely to occur between 7-9am on Saturday morning along the I-95 corridor, before for those areas northwest of D.C.
Rain will continue through southern Maryland and the eastern shore at this time, just will pick up in intensity.

By the mid to belatedly morning hours, most of the region changes over to winterly precipitation, with snowfall around D.C. and the I-95 corridor, with some mix expected down beyond lower southern Maryland and the Northern Cervix.
Snow could come up down moderate to heavy for a period of time. Every bit nosotros head into the afternoon, the system should get-go to pull away. Snowfall showers and possibly a snow squall or two could remain into the early evening hours every bit an upper trough swings through the region though.
Winds volition get very gusty, potentially to dissentious levels, with gusts over 50mph possible as the storm intensifies as it pulls away. Temperatures will continues to plummet through the evening and into the overnight hours.
Pinpointing accumulations is extremely difficult when we are talking well-nigh a pelting-to-snow situation. Information technology is twice as difficult during the month of March, when warm footing temperatures and a high sun bending can all impact how much snow is able to stick.
With marginal temperatures past the transition, this will be a wetter diverseness snowfall. A lot of information technology will melt on contact, peculiarly on the paved surfaces. Accumulations will depend heavily on snowfall rates.
Anything too light would just autumn equally a "white rain" that melts on contact, while heavier rates could add together up to a slushy inch or ii. Pre-treatment of roadways is non likely to be too effective, every bit rain overnight which could exist heavy in its own right could wash away whatever table salt or chemicals are on the roadways.
While we are not anticipating bit probables on the major roadways, watch out for some of those lesser travel side roads to become a slushy coating. Thankfully this is all happening on a Saturday morning time, when traffic is much lighter than a weekday.
Most areas northwest of boondocks we are expecting i-3" of snowfall, again mostly on grassy and elevated surfaces. Some scattered areas up that mode could choice upward more. Around D.C., we expect a coating to up to 2" of snow, and look most of it will be confined to the grassy surfaces as well.
That being said we do take a few weather models this morning time suggesting that amounts could come up in a little higher than expected. This morning'south European (shown above) indicates the potential for more than 3" of snowfall in Washington, which would make information technology the 2d-largest snowfall of the wintertime if true.
The National Weather condition Service is closely watching model guidance as well. They rely heavily on a model known as the NBM, the National Alloy of Models, which is essentially a alloy of model and ensemble guidance to create a forecast.
Recent runs of this model have suggested as much equally 2-4" in the DC region, with as much equally four-vi" along the I-66 and I-270 corridors. This would likely be a high terminate, or "boom" scenario for snowfall across the region.
Just there is the threat that as the upper level features with this storm arrangement swing through, there could be ane more outburst of heavy snowfall that might surprise some folks, and put downwards a quick inch or ii.
Winter Atmospheric condition Advisories were issued this morning to cover those regions well-nigh likely to encounter disruptive snowfall accumulations. Parts of Montgomery, Loudoun, Howard, and Fauquier counties were all included in this advisory.
Nosotros doubtable that D.C. and Baltimore will be included in a wintertime conditions advisory update later this afternoon, based on some aggressive morn guidance that has come in. Wintertime Tempest Warnings are in place for some of our mountain regions, where over half a foot of snowfall will be possible in elevated regions.
While the snow will grab the headlines, 1 of the bigger stories with this storm will exist the sudden drop in temperatures.
They will fall all solar day on Saturday, and we volition probable exist in the 20s past dusk on Saturday evening. Winds will exist extremely gusty, perhaps fifty-fifty dissentious, equally gusts could roar over 50mph. Wind chills if you are out and about on Sat night volition be in the teens and unmarried digits.
Merely Sunday, winds will start to lighten, but temperatures will plummet into the teens equally skies clear out on Sunday morning. Sunday will be a winter similar 24-hour interval, with temps in the teens to start and the 40s by the afternoon.
Speaking of the weekend, it is actually the last full weekend of winter! And that means it is time to kick those clocks frontwards 1 hour Saturday night before you caput to bed. Starting Sun, the sun will set afterward 7pm as nosotros return to Daylight Saving Time.
More proficient news in the final workweek of winter should experience a lot more like jump! 60s are back by Monday afternoon, and should remain there through next weekend and likely the week beyond also. This storm really does wait like winter'southward last wallop!
