A Wind Advisory remains in effect until 10am this morning.
Mid Week will feature well below normal temperatures with a clipper system bringing us our 1st flakes on Wednesday. See more on the snow potential in the Snow Lover's Crystal Ball at the bottom of the post.
It will remain very windy today with 15-20 mph winds, occasionally gusting over 25mph. Winds will die down some toward sunset. It will be mostly sunny with some high clouds on the increase this afternoon. Highs will be 5-10 degrees below normal in the low to mid 40s. Overnight clouds will be on the increase as a clipper system (see more below in the SLCB) approaches from our northwest. There is a 20% chance of light snow/snow showers developing from west to east during the pre-dawn hours with lows in the upper 20s to around 30.
WednesdayLight Snow, Cold.
Snow will likely (70%) overspread the area from west to east during the early morning hours and continue throughout the day. Temperatures will remain cold with highs in the low to mid 30s. Snow will taper after sundown with minor accumulations possible. Lows will be in the mid to upper 20s. See more on the snow potential at the bottom of the post.
Thursday will be partly to mostly sunny and cold. Afternoon highs will be in the mid to upper 30s. Overnight, clouds will be on the increase with lows cold again in the upper 20s to low 30s.
A Look Ahead
- On Friday a storm system cutting to our west will begin to usher in more seasonable air and a slight chance of late rain showers as highs make it near 45.
- The weekend currently looks unsettled with a return to somewhat milder air. There is a slight chance of showers on Saturday with a better chance late on Sunday. Highs will be near 50.

For the 7th consecutive month, DC finished with at or above normal temperatures. Additionally as mentioned by Jason on Saturday
, November capped off the warmest meteorological autumn on record in DC. November finished at 1.1 degrees above normal with only 1.46" of rain (we are at 82% of normal precipitation year to date). The month was pretty varied with 15 days at or below normal and 15 days above. We had 12 days with a high temperature of 60 or higher and 9 days with highs of 50 or lower. Our 1st freeze, and only so far season to date, occurred on November 24th, just slightly later than our average first freeze date of November 15th. All in all it was your standard issue November. Pretty normal and pretty unmemorable, which may be good or bad depending on your perspective.
Snow Lover's Crystal BallNext Chance of Accumulating Snow:
Wednesday, December 5th.Probability:
70%Potential Impact:SchoolCast (for Wed): (early dismissal also a possibility)Commentary:
A clipper system approaching from the northwest will spawn light snow spreading from west to east over the area near sunrise. As temperatures will be near or below freezing, untreated roads may see some light accumulation as we head into rush hour, especially in the western suburbs. During the day on Wednesday snow will continue off and on with perhaps some moderate snow late in the day.
With temperatures at or above freezing in most places, snow will mainly accumulate only on grassy surfaces. However, areas to the north and west that see the temperature at or below freezing may see some accumulation on all surfaces. Snow will taper in the evening, with perhaps some additional light accumulation. This will not be a uniform event. Areas north and west of town will see colder temperatures and higher accumulation, while DC and south and east may only see light accumulation on car tops and grass. Either way it looks like a minor early season nuisance snow. Some reports of 2-4" are possible, but most of us will see a coating up to 1-2".
