FORECAST IN DETAIL

Finally, a cold front with some bite delivers a legitimate winter chill to start off this first week of 2012. Today temperatures struggle to gain any forward momentum and Tuesday we‘re hard pressed to reach freezing. But we won’t even have time to acclimate to this cold, as warmer than average temperatures return late in the week. No significant precipitation looms on the horizon.

Snow Potential Index: 1 (→) - Despite cold, even flurries hard to come by. Might be something early next week, but pretty iffy.

Today (Monday): Skies are partly sunny, but today it’s about as cold as it’s been this winter. Temperatures don’t rise much during the day as brisk winds from the west at 10-20 mph draw in Arctic air. Highs (during the day) range from the upper 30s (north of D.C.) to the low-to-mid 40s (south of D.C.). Confidence: Medium-High

Tonight: In a typical winter, tonight’s combination of wind and cold temperatures would feel cold, but in light of the recent mild conditions, it feels downright brutal. Lows range from 21-26, but wind chills are in the teens. Skies are partly to mostly cloudy, and a snow flurry can’t be ruled out (10-20% chance). Winds are from the northwest at 10-18 mph. Confidence: Medium-High

Tomorrow (Tuesday): The coldest day of winter (so far), easily, and windy. For the first time, highs don’t get out of the 30s, and may struggle to even reach freezing from the District and points north; all this, despite sunny skies Highs range from 30-35. And it feels significantly colder with winds from the northwest at 15-25 mph with some gusts over 30. Confidence: Medium-High

Tomorrow night: Winds relax a bit (but not completely) and temperatures take a dive. Under mostly clear skies, lows range from the mid-teens in the cooler suburbs to the low 20s downtown. Confidence: Medium-High

A LOOK AHEAD

A steady warming trend covers the period Wednesday through Saturday. Wednesday is still chilly with highs 35-40, but we tack on about 5 degrees each day through Saturday. So highs are 40-45 Thursday, near 50 Friday and in the mid-50s by Saturday. Thursday morning’s lows are 20-28 (suburbs to city), moderating to 23-32 Friday, and 26-35 Saturday. Sky conditions are partly to mostly sunny each day and mostly clear at night. Confidence: Medium

On Sunday, we see increasing clouds and more mild temperatures, with lows 32-40 (suburbs-city) and highs in the mid-50s.
