Today (Monday): Make sure you wear a lot of layers and hats, gloves and scarves. Wind chills this morning will range from minus-5 to minus-15 and will recover only into the single digits this afternoon. Actual air temperatures will slowly moderate from the low teens to low 20s, but the winds - sustained around 20 mph gusting to 30 to 40 mph - will be brutal. The sunshine isn’t going to make things feel much better. Confidence: Medium-High

Tonight: Teeth-chattering cold will be felt this evening as temperatures fall back into the teens and wind chills slip back to near zero. Overnight, under clear skies, lows will range from the high single digits in our colder spots to the mid-teens or so downtown. Winds are from the northwest around 10 mph, with some higher gusts - especially early on. Confidence: Medium-High

Tomorrow (Tuesday): Mercifully, the wind will relax but, even so, it will be a very cold day. Even with sunshine, highs will stay below freezing in most spots, maybe touching 33 or 34 degrees from the District to the southeast. Confidence: Medium-High

Tomorrow night: Some increasing high clouds and not as cold. As light winds from the south filter in, temperatures may even rise a bit overnight, with evening lows in the 20s increasing to near freezing by morning. Confidence: Medium-High


Clouds will increase Wednesday with rain developing between the midmorning and early afternoon hours. Rain then will continue intermittently through Thursday morning. Some gradual clearing is then possible Thursday afternoon. Highs both days will be near 50, with lows in the 40s. Confidence: Medium

A cold pattern will return Thursday night through the weekend, with highs mostly in the 30s and lows in the 20s. It will be dry more often that not, but we cannot rule out some snow showers Friday. There’s an outside chance of some snow developing by late Sunday but you’ll want to check back to see whether this threat sticks. Confidence: Low-Medium
