It is mid-January after all, so I guess we can’t complain too much about any cold days we get. And, we’re going to get one today. It’s another one of those “sure looks nice out the window” days. But stepping outside is another matter altogether, with highs barely breaking the freezing mark. Fear not, milder air is on the way as a storm system approaches early in the week, behind which we cool down again.

Snow Potential Index: 1 (→) - Keeping at 1 due to small chance of mix Monday night. But this just doesn't look like a snow lover's January.

Today (Sunday): One good thing about high pressure building in? Any lingering morning clouds get cleared out of our sky. One not-so-good thing? It brings with it reinforcements of cold air. Despite mostly sunny skies, we’re not looking to go much higher than the mid-30s for highs. We still have a bit of a breeze from the north/northwest, but nowhere near as gusty as it’s been. Confidence: High

Tonight: With high pressure centered directly overhead, skies are plenty clear. And the air is plenty cold. Lows overnight get down to mainly the low-to-mid 20s, with some upper teens possible in the coldest burbs. Winds go calm early, maybe blowing lightly from the south toward morning. Confidence: High

Tomorrow (Martin Luther King Jr. Day): The high pressure center moves off the Southeast coast and that turns things briefly warmer. Mostly sunny skies become cloudier toward or during afternoon as highs reach the low-to-mid 40s and our next storm system approaches. A stray sprinkle or two is possible by evening, especially in our western zones. Confidence: High

Tomorrow night: With a warm front just to our south, chances for some rain showers increase to around 30-40%, with a small chance of a few probably harmless snowflakes or sleet pellets mixed in. With breezes from the south, cloudy skies and increasing humidity, lows shouldn’t dip much lower than the mid-30s. Confidence: Medium-High


A broad but somewhat disorganized system works its way by on Tuesday. We should see mostly cloudy skies and a few waves of rain showers come through (70% chance) ahead of a cold front. Also ahead of the front, temperatures continue their upward trend with highs in the low-to-mid 50s. Mild, but likely wet. Confidence:Medium

Tuesday night, any lingering showers come to an end as the cold front comes through. Clouds clear out toward morning as colder, drier air makes its return. Nighttime lows drop to near freezing. Confidence: Medium

Wednesday skies should become mostly sunny in the wake of the cold front. It won’t be super cold, with highs in the upper 30s to low 40s. But gusty winds from the northwest bring a chilly bite, blowing at 15-25 mph with higher gusts. Confidence: Medium
