Wintry start to last day of 2009
Slippery travel for New Year's Eve morning
Air temperatures are at or below freezing area-wide, ground temperatures are cold as well, and precipitation is streaming toward the D.C. area from the southwest. The combination spells the likelihood for a wintry mix and slippery travel early Thursday.
Now through the a.m. commute: Precipitation should move in from the southwest and south some time between 2 a.m. and 6 a.m. and could contain a mix of snow, sleet and freezing rain. Any snow and sleet accumulations should be minor (up to 1-2 inches), but could be enough to slicken roads at least through the morning rush, especially with some freezing rain in the mix.
Late morning & afternoon: Things should improve by late morning as temperatures start to inch upward and precipitation begins to exit to the east/northeast, possibly ending as some plain rain or drizzle in some places. Any iciness will likely linger the longest north and west of town, where temperatures will be slowest to warm above freezing. By noontime it should all be over, and the afternoon looks cloudy but mostly dry with highs trying to reach the upper 30s.
How do things look for tomorrow evening and the start of 2010? See our full forecast through the weekend.
