Mike Thomas has the FOX 5 Weather forecast for Friday, March 11
Friday will actually be a dainty spring say with sunshine and temperatures reaching the lower 60s, but winter volition begin to make its return later on the midnight hour this night.
Rain shower are likely to start overspreading the region east of the I-81 after the midnight hour this night. Temperatures volition probable be in the upper 40s and lower 50s effectually the region, and then all rain is expected at onset.
Rain will intensify every bit a storm system to our southward begins to strengthen and push northwards towards our beaches. Saturday's high temperatures will be gear up before the sun e'er comes up.
By the sunrise hours, temperatures start taking their tumble. The timing of this absurd down will be absolutely key for how fast rain transitions over to a period of snowfall, but most weather guidance suggest it is likely to occur between seven-9am on Sabbatum morning along the I-95 corridor, before for those areas northwest of D.C.
Rain will go on through southern Maryland and the eastern shore at this time, but volition pick upwards in intensity.

By the mid to late forenoon hours, most of the region changes over to winterly atmospheric precipitation, with snow around D.C. and the I-95 corridor, with some mix expected downwardly across lower southern Maryland and the Northern Neck.
Snow could come down moderate to heavy for a period of fourth dimension. Equally nosotros caput into the afternoon, the system should beginning to pull away. Snow showers and peradventure a snowfall squall or two could remain into the early evening hours as an upper trough swings through the region though.
Winds volition get very gusty, potentially to damaging levels, with gusts over 50mph possible as the storm intensifies as it pulls away. Temperatures will continues to collapse through the evening and into the overnight hours.
Pinpointing accumulations is extremely difficult when we are talking well-nigh a rain-to-snow situation. Information technology is twice as hard during the calendar month of March, when warm ground temperatures and a high sun angle can all affect how much snow is able to stick.
With marginal temperatures by the transition, this will exist a wetter multifariousness snowfall. A lot of information technology will melt on contact, particularly on the paved surfaces. Accumulations will depend heavily on snowfall rates.
Anything as well light would simply fall as a "white pelting" that melts on contact, while heavier rates could add up to a slushy inch or two. Pre-treatment of roadways is not likely to exist as well constructive, as rain overnight which could exist heavy in its own right could wash away any 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 get a slushy coating. Thankfully this is all happening on a Sabbatum morning, when traffic is much lighter than a weekday.
Almost areas northwest of town nosotros are expecting 1-3" of snow, once again mostly on grassy and elevated surfaces. Some scattered areas up that way could pick up more. Around D.C., we wait a coating to up to 2" of snow, and expect most of it will be confined to the grassy surfaces as well.
That beingness said nosotros do have a few weather models this forenoon suggesting that amounts could come up in a picayune higher than expected. This morning time's European (shown above) indicates the potential for more than three" of snow in Washington, which would make it the 2nd-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 Blend of Models, which is substantially a blend of model and ensemble guidance to create a forecast.
Recent runs of this model have suggested every bit much as 2-4" in the DC region, with as much as iv-6" along the I-66 and I-270 corridors. This would probable exist a high end, or "nail" scenario for snow across the region.
But at that place is the threat that as the upper level features with this storm system swing through, there could exist one more flare-up of heavy snow that might surprise some folks, and put down a quick inch or two.
Winter Weather condition Advisories were issued this morn to cover those regions near likely to see disruptive snowfall accumulations. Parts of Montgomery, Loudoun, Howard, and Fauquier counties were all included in this advisory.
Nosotros doubtable that D.C. and Baltimore volition exist included in a wintertime weather informational update later this afternoon, based on some aggressive morning guidance that has come in. Winter Storm Warnings are in identify for some of our mountain regions, where over half a pes of snowfall will be possible in elevated regions.
While the snow will catch the headlines, one of the bigger stories with this storm will exist the sudden drop in temperatures.
They will fall all day on Saturday, and we will probable be in the 20s past sunset on Sabbatum evening. Winds will be extremely gusty, perhaps even damaging, as gusts could roar over 50mph. Wind chills if y'all are out and about on Sabbatum night volition be in the teens and unmarried digits.
But Sunday, winds will outset to lighten, merely temperatures will plummet into the teens as skies clear out on Sunday morn. Sunday will be a winter like mean solar day, with temps in the teens to starting time and the 40s by the afternoon.
Speaking of the weekend, it is actually the terminal full weekend of winter! And that means it is time to kick those clocks forward one hour Saturday night before yous head to bed. Starting Sunday, the sun will set after 7pm as we return to Daylight Saving Fourth dimension.
More good news in the final workweek of winter should feel a lot more like bound! 60s are dorsum by Mon afternoon, and should remain there through next weekend and probable the week beyond too. This tempest really does look like winter'southward terminal wallop!
