A Dense Fog Advisory is in effect this morning until 10am for most the of the DC Metro area, including all of Montgomery County.
Clouds will stick around after the fog this morning , but the sun should start peek through and temperatures will likely reach the mid 70s in the afternoon.
Snow totals are in from across the county after today’s snow storm that made things messy from the morning until the early afternoon across the area.
The forecast for this storm was fairly accurate, as expected snowfall for the area were between 2-5” depending on your location in the county
Per the National Weather Service, “rapidly deteriorating conditions expected across the Washington and Baltimore metropolitan areas as well as northeastern Maryland by 9 AM this morning as rain changes to heavy snow. Rates of 1-2″ per hour are possible at times with gusty winds.”

Winter Storm Warning (NW MoCo)
A Winter Weather Advisory is now in effect for all of MoCo from 7am until 3pm on Saturday.
Per the National Weather Service:
A winter weather advisory has been issued for Northwest MoCo. This generally includes areas beginning at Germantown and points north/west (Clarksburg, Damascus, Poolesville, etc.).
Central/SE MoCo is not currently included in the advisory, as a little less precipitation is expected (see maps below). I fully expect all of MoCo and most of the DC Metro area to be included in the advisory later this morning.
This morning we let you know that a period of snow is possible on Saturday following rainfall early in the day. Temps will drop into the 30s on Saturday afternoon and eventually the 20s. If they drop soon enough, we’ll likely see the rain change to snow before the system heads out.
The latest update from the National Weather Service has almost all of MoCo in the 1 inch range with Damascus in the 1-2″ range. Below you’ll see the latest ‘Forecaster’s Discussion’ per the NWS:
Temperatures are expected to reach the low 50s today, but before we get there we’ll have to deal with some patchy fog and cold temperatures this morning that could cause a few slick spots. Below you”ll see an update from the National Weather Service:
Patches of dense fog has developed east of the Blue Ridge Mountains early this morning. With temperatures near or below freezing, there may be a few slippery spots during this time.
