Today's bitter arctic blast brought us the coldest air of the season so far and beats last week's cold by about ten degrees. D.C. dropped down into the 20s for the first time and wind chill temperatures were down in the the teens and even single digits in a few spots.

Lows this Morning

Believe it or not, our high temperature actually happened at midnight with 42 degrees and then plummeting temperatures through sunrise. This afternoon will recover a bit, but temperatures only warm a few notches in the low to mid 30s. That is more typical of January temperatures! And it isn't just the temperatures making it feel unreasonably cold. Gusty winds will keep our wind chill factor in the 20s all day long. Wind gusts will reach 25 to 30mph at times. Here's a look at ABC7's computer model forecast wind chill temperatures this afternoon.

Forecast Wind Chill this Afternoon

The wind will diminish after sunset, so that will help, but clear skies means a cold night ahead. Record lows are in jeopardy tonight. The record low for Dulles is 20. I'm expecting to meet or just break that record. Reagan National's record low is 18, and I think we'll miss that by just a few.

Lows Wednesday Morning

Additional records may be set Wednesday afternoon. Highs will only reach the low to mid 30s. We could have the coldest high temperature on record for the date. Here at the stats for that.

Record Cold Highs Wednesday?

By Thursday, we start a slow recovery with temperatures back in the 40s. A dry cold front will pass our area, but won't bring the temperatures down too much more on Friday. For those of you hating on the cold, we'll reach near average temps in the mid 50s late this weekend and should easily top 60 on Monday. The warmer temperatures won't stop there.

 

6-10 Day Temperature Probability

The 6-10 day outlook has much above average temperatures for the Mid-Atlantic and that should last into the first part of December. Hang in there!
