The cold front passage of yesterday ushered in below normal temperatures that will last through the weekend. Expect temperatures 5-10 degrees below normal, or more characteristic of early to mid December.
A chilly late Autumn day is on tap to start the weekend. Sunny skies will prevail with a biting northwesterly wind gusting to 25-30 mph. Afternoon highs will only reach the upper 40s to near 50 degrees. Overnight it will be breezy, but with slowly diminishing winds. It will be cold, with lows from the mid 20s (suburbs) to mid 30s (downtown).
Winds will shift to the south, but under partly to mostly cloudy skies, temperatures will remain slightly below normal. Look for afternoon highs in the low 50s. Overnight there will be a 25% chance of some light rain showers possibly mixing with or changing to snow as a clipper system moves to our north. Low temperatures will be in the mid to upper 30s and any light mix/snow that might fall will not accumulate or have any meaningful impact.
There may be a lingering morning sprinkle or flurry (20%). It will remain cool with afternoon highs only rising to the mid to upper 40s. Overnight skies will clear and winds will calm allowing temperatures to plummet to the mid to upper 20s.
A Look Ahead
- Early next week look for mostly dry conditions and a gradual warming trend with highs climbing through the 50s into the low 60s.
- Thanksgiving currently looks cloudy and warm with temperatures reaching the low to mid 60s. However, a potent cold front will likely strike early in the weekend leading to possibly our coldest temperatures to date for Thanksgiving weekend.

Bob Ryan's Winter Outlook
Long time NBC Channel 4 chief meteorologist, Bob Ryan, released his 2007-08 winter outlook
on the air last night. The main factors Bob considered in developing his forecast were moderate La Nina conditions, the recent drought, the late onset of autumn, and persistently above average temperatures to date in 2007. Bob suggested that overall temperatures for the coming winter will be near or above normal. However, he feels that in addition to a primary storm track up the Appalachians that typically brings us rain, the other main storm track will be a classic snow maker for DC. As such, he expects above average snowfall for DC this winter for the 1st time since 2002-03. Our 2007-08 winter outlook will be released on Tuesday. Just in time for a Thanksgiving weekend that could feature some volatile weather. Stay tuned.
