FORECAST IN DETAIL

Chin up, everybody! Yes, we may still see considerable clouds today. But generally speaking, yesterday’s damp doom and gloom is gone after the morning fog. After another day on the mild side today, we’re colder tomorrow into the holiday weekend. We do have a few snow chances along the way. And by snow chances, I mean the kind we’ve come to expect around here more often than not — the potential for a bit of light snow that probably won’t accumulate much, if at all.

Temperature Map

Today (Wednesday): The overall look is less gloomy than yesterday after the morning fog. Even so, skies are probably partly to mostly cloudy as highs head for the upper 40s to near 50. It’s a mostly quiet weather day with light winds, though we can’t rule out a passing light rain shower during the early-to-mid morning, and a passing rain or snow shower during the mid-to-late afternoon. No accumulation expected. Confidence: Medium-High

Tonight: A passing rain or snow shower remains possible but that’s about it, and again no accumulation expected. Winds from the northwest increase to 10-15 mph as temperatures drop toward overnight lows in the upper 20s to mid-30s, under mostly to partly cloudy skies. Confidence: Medium-High

Tomorrow (Thursday): Between weather systems to our northwest across the Great Lakes and to our east off the coast, we should be sitting mostly pretty with partly sunny skies, after the chance of an early-morning snow shower. The main drawback is colder highs in the upper 30s to low 40s. But hey, that’s only a touch below average for mid-January. Breezes should be near 10 mph from the northwest. Confidence: Medium-High

Snow Potential Index

2 (↓) Series of weak systems through Sunday may struggle to produce even a dusting, unless one strengthens more than currently expected.

Tomorrow night: All is quiet Thursday night, with partly to mostly cloudy skies and lows mainly in the upper 20s to low 30s. Confidence: High

A LOOK AHEAD

A weak upper-level system produces plenty of clouds Friday – we’ll call it mostly cloudy — but probably can’t squeeze out more than an occasional light rain or snow shower at the most, as highs rise into the 40s. Friday night into Saturday morning presents a little better chance of snow showers, but only if low pressure forming off the cost doesn’t do so too far off the coast. Accumulation doesn’t look likely, but a light one can’t be ruled out yet. Lows dip to the upper 20s to low 30s. Confidence: Medium

Clearing skies should arrive by Saturday afternoon as highs reach near 40, though clouds may increase again as yet another weak system approaches late in the day. Snow showers are possible Saturday night, and while right now they appear too few or too light to matter much, we’ll have to keep an eye on things since lows are expected in the 20s. Confidence: Low-Medium

The somewhat active pattern takes a break for Sunday and MLK Monday. Both days should feature partly to mostly sunny skies, with highs in the 40s on Sunday and perhaps near 50 on Monday. Confidence: Medium
