9:39pm: The changeover to rain across the area is almost complete. But many parts of the region still have surface temperatures below freezing. This means the rain is freezing on contact when it falls .And now you have a real-time description of what freezing rain is.
During the balance of the night, at different rates, at different times, in different areas, surface temperatures will rise above freezing and that trend will continue through the day tomorrow. But until all areas are several degrees above freezing, icy roads, sidewalks and parking lots will continue to be a major impediment to drivers and pedestrians.
Conditions will be much improved by sunrise when temperatures will be above freezing across the entire region. So until then, our advice is simple. Unless you absolutely must venture out…stay off the roads tonight. And as an unwelcome bonus, many areas will be dealing with areas of fog overnight, as well.
5:42pm: It appears the transition has occurred for the majority of the region with sleet and freezing rain now mixing in with the snow. At this time, some locations are still seeing snow but as we head into the next few hours, more sleet and freezing rain is expected.
Some of the latest guidance (which I'm not even sure why I'm bringing up since it's been pretty terrible today) is thinking temperatures will get closer to freezing by 9pm or 10pm. It has reached the mid to upper 20s in D.C. and the 30 degree mark in the far southern parts of the viewing area. At this point I think guidance isn't too far off and temperatures should make the freezing mark prior to midnight.
By tomorrow morning, temperatures should be in the mid to upper 30s and rise into the 40s by lunch time. Highs Sunday should still reach the low to mid 40s.
5:03pm: We are finally getting some reports of a change to sleet in areas such as Winchester, Bristow in Virginia and a change to freezing rain in Southern Maryland.
Most areas west of I-95 have recorded snowfall totals around 6 inches or more. Here is the latest preliminary snowfall totals list from NWS Sterling.
4:11pm: Snow is continuing to be the primary form of precipitation and should continue to be so over the next few hours. We're expecting the transition to sleet and freezing rain closer to 7pm now, and a transition to rain will happen closer to 9pm or later.
Surface temperatures have reached the mid 20s around D.C. and have pushed closer to the 30 degree mark south of D.C. near Fredericksburg and Southern Maryland. St. Mary's County in MD has already seen a transition to sleet and areas in the Northern Neck.
This transition should slowly but surely move north into the D.C. area over the next few hours. We'll be keeping a close eye on temperatures!

2:20pm: Meteorologist Steve Rudin and myself just took a stroll outside to make a quick facebook video post. You can find it here.
1:55pm: Areas of heavy snow continue along and just west of I-95. Locations in western Fauquier and Loudoun Counties are experiencing a lull in the precipitation.
The heaviest snowfall currently extends from Culpeper north to Prince William, Fairfax and Montgomery Counties.
1:36pm: Roads across the D.C. area are snow covered with the worst conditions north and west of the city. I recently talked to Chief Meteorologist Doug Hill who said he hasn't even seen a flake of snow in Southern Maryland, so this will be a very sharp cut off of a storm!
Below is a look at I-66 east around 11am. Conditions have deteriorated quickly.

1:30pm: Areas of snow will continue to fall over the next few hours before changing over to sleet and freezing rain we think around 4-7pm. Currently, temperatures are getting into the upper 20s and low 30s south and east of town, where little to possibly even no snow is possible in Southern Maryland.
Areas north and west of D.C. have already received 3 to 4 inches of snow and will continue to see additional accumulations through the afternoon.
