FORECAST IN DETAIL
What does December want with us? We are expecting this month to be colder than normal for the Washington DC area and I believe we are still on track to do that, but the day-to-day details in the current forecast suggest December does not know what it wants. Over the next five days, we'll see temperatures in the 30s, 40s, 50s. We'll see sun, we'll see showers, and dare we say a few flurries this coming weekend? So get ready for a little bit of everything.
Today (Tuesday): A large upper level low pressure will be swinging through the area. The air mass with it is relatively cool so temperatures should be below normal today with scattered cloud cover. Winds from the west at 5-10 mph will add to the chill. Confidence: High
Tonight: Partly cloudy conditions are anticipated tonight, but winds will turn toward the calm side. This will allow for freezing temperatures around the area. Look for a suburb to city range of 25-30. Confidence: High
Keep reading for the forecast through the weekend.
Tomorrow (Wednesday): High pressure and a moderating air mass should make Wednesday the best day of this week. Look for temperatures to return to near normal levels, lots of sunshine, and gentle breezes. Confidence: Medium-High
Tomorrow Night: Winds will shift more from out of the south and clouds will make a re-appearance. Look for warmer low temperatures in the 30-35 range (suburbs-city). Confidence: Medium-High
Thursday is our "fropa" day. Impress your friends by telling them that "fropa" means frontal passage. We'll be watching a cold front come through in the afternoon hours and that could mean showers (30% chance right now) with a near 100% likelihood of cloud cover. Highs should still get to normal levels. Look for a 49-53 range. Chillier weather moves in that night with lows 24-28 (suburbs-city) with some wind chill. Confidence: Medium
Friday is our coldest day of the work week as I doubt we'll even hit 40 degrees in most locations. Look for a realistic range of 35-39 for high temperatures with intermittent cloud cover too. Lows Friday night should fall in the lower to middle 20s (suburbs-city). Confidence: Low-Medium
The weekend is setting up to be very cold as we remain under the influence of a Polar air mass. Highs should mainly be in the 30s with lows deep into the 20s and probably some teens in the outer suburbs. Mostly sunny skies are expected on Saturday, but a disturbance Saturday night into Sunday morning could trigger a few flurries. Confidence: Low-Medium
