The bitterness of January has retreated but winter-like weather is holding strong. Two decidedly cold days kickoff the week before low pressure develops in the Gulf of Mexico and charges towards the Mid-Atlantic Wednesday. Depending on its exact track and speed, snow could break out as early as Wednesday afternoon, with snow or mixed precipitation continuing Wednesday night into Thursday. Temperatures may moderate a little Friday (passing 40 perhaps?) but then another cold front – with a brief round of snow or rain showers – zips through Friday night cooling it back down for the weekend.

Today (Monday): Watch out for any slick spots from wet roads that might have frozen overnight early on. Partly to mostly cloudy skies dominate the balance of the day, and it’s cold. Highs struggle to reach freezing in our colder north and west suburbs with some mid-30s from the District and to the south and east. Winds are from the northwest at around 10 mph. Confidence: Medium-High

Tonight: Partly cloudy skies and very cold with arctic high pressure moving over the region. Lows are mostly in the teens except near 20 downtown. Light winds. Confidence: Medium-High

Tomorrow (Tuesday): Arctic air is control with sub-freezing highs for much of the area. Fortunately, it’s not terribly windy and there’s a bit more sun compared to Monday. Highs range from the upper 20s to low 30s. Winds are from the north at 5-10 mph. Confidence: Medium-High

Tomorrow night: Mostly clear and very cold. Lows are once again in the teens to near 20 (downtown). Confidence: Medium-High

A LOOK AHEAD

Snow Potential Index

A daily assessment of the potential for at least ~1″ of snow in the next week, on a 0-10 scale.

6 (↑) Wed-Thurs forecast tricky, but odds of both a little and more than a little snow have increased.

Increasing clouds Wednesday with a chance (40-50 percent chance) of snow developing during the afternoon, especially in southern areas. Highs are in the upper 20s to low 30s. Snow is likely Wednesday night (60 percent chance), possibly mixing with and changing to sleet and freezing rain, especially along and east of I-95.  There’s still a small chance the bulk of the precipitation misses us to the south and east. Temperatures are steady in the upper 20s to low 30s. Confidence: Low-Medium

Snow and/or mixed precipitation tapers by around midday Thursday (50 percent chance) followed by partial clearing and breezy conditions. Highs range from 32-37. Partly cloudy to mostly clear Thursday night, with lows in the 20s. Confidence: Low-Medium

Programming note: CWG’s Wes Junker will post an in-depth analysis of the Wed-Thurs storm early this afternoon

Mostly sunny Friday morning, followed by increasing clouds. Highs probably sneak into the 40s as winds from the south come in briefly. A cold front zips through the region Friday night with a 40 percent chance of rain and/or snow showers. Lows dip into the upper 20s to low 30s (downtown). Confidence: Medium

Partly sunny, breezy and chilly Saturday, with highs in the 30s to near 40.  Increasing clouds Saturday night, with lows in the 20s. Confidence: Medium

Another weather system probably scoots through the region Sunday, with one more chance of rain and snow showers.  Highs are near 40. Confidence: Low-Medium
