  1. DCA temp 9z: 45 12z: 38 BWI temp 9z: 40 12z: 33 Total snowfall IAD: 0.4" DCA: T BWI: 0.8" highest spotter report in LWX: 7.5"
  2. 65 right now after hitting a high of 70 around noon.
  3. IAD has 1.0" on the season.
  4. Temp steady at 35, dewpoint starting to edge down so hopefully I can get down to freezing soon.
  5. 37 degrees right now. Was at 41 an hour ago.
  6. So far, looks like HRRR is favoring areas SE of DC:
  7. Sterling AFD: .SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/... The upper-level trough will remain overhead through Monday before ridging finally builds in Monday night. Most of Sunday should turn out dry and seasonably chilly since the area will be in between shortwaves. Max temps will range from the 20s in the mountains to the middle 40s near Washington and Baltimore. A potent shortwave will rotate around the trough...passing through the area Sunday night. The upper-level trough overhead will shift from a positive tilt to a shifts from a positive tilt toward a neutral tilt in response to this energy...and you can see reflection of this system down to the surface in the form of an inverted trough and weak surface low. Guidance has begun to converge on a solution that brings a period of light snow Sunday night...but perhaps it will be a bit earlier than previously expected. Tweaked the forecast to have the most likely period of snow to be later Sunday evening into the overnight hours. Subsidence behind the shortwave likely will cause precipitation to diminish in coverage toward the morning rush on Monday. However...slippery roads are possible through the morning rush since temperatures will be below freezing. The upper-level trough will begin to shift east Monday and a northwest flow behind the departing area of low pressure will bring colder conditions. Scattered snow showers are possible due to instability and shortwave energy associated with the upper- level trough. Although coverage appears that it will be scattered...some areas may get another coating of snow during this time. Max temps will be in the mid to upper 30s across most locations...so pavement temperatures should rise above freezing late Monday morning. High pressure will build overhead Monday night. Dry and seasonably cold conditions are expected.
  8. Wow, the long range outlook sure did deteriorate quickly. No better time for a winter cancel than now!
  9. Just about done here, got close to an inch of snow.
  10. Darn, right in the middle of that snow hole. Oh well, congrats to everyone who got a decent snowfall out of this.
