FORECAST IN DETAIL

Yesterday’s cold rain and drizzle was about as miserable as it gets around these parts. While we may not see the sun again until early tomorrow, today does offer some modest improvement after any early showers or drizzle. The sun goes on hiatus again by later tomorrow into Friday, however, and rain chances increase Friday into the weekend.

Today (Wednesday): Showers remain a risk early this morning and some areas of drizzle or fog may linger into mid-morning. Mostly cloudy skies hang on even longer, probably well into the afternoon if not through sunset. Even with the clouds, temperatures should recover nicely after yesterday’s chill, thanks to a mild breeze from the southwest near 10 mph. Afternoon highs reach the mid-to-upper 50s. Confidence: Medium-High

Tonight: A cold front pushes through Wednesday evening. That leads to clearing skies as winds shift to come from the northwest. Lows range through the 30s, from the low-to-mid 30s in the outer suburbs to the upper 30s downtown. Confidence: High

Tomorrow (Thursday): High pressure builds in and provides partly sunny skies, which may turn partly to mostly cloudy during the afternoon. A light breeze from the north brings back the chill as highs plateau in the mid-to-upper 40s. Confidence: High

Tomorrow night: Skies turn mostly cloudy as high pressure retreats to our north. Temperatures are similar to tonight, though the clouds might keep suburban areas a touch warmer. Look for lows in the mid-to-upper 30s. Confidence: Medium-High

A LOOK AHEAD

Friday may see a bit of light rain during the day, maybe a touch of light mixed precipitation north and west of town, with overall precipitation chances around 30-40%. At the very least it should be a mostly cloudy day, with highs heading for the mid-to-upper 40s once again. Rain showers become a little more likely Friday night, though they may be of the light variety, as lows dip to the mid-30s to near 40. Confidence: Low-Medium


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

1/10 (↓): A few flakes could mix with rain/sleet in N&W burbs on Friday. Temps above freezing though.


A stalled front, and the potential for low pressure to develop along it, means we could see a few different periods of rain during the course of the weekend. We’ll try to pinpoint the timing as we get closer. But for now plan on the possibility of rain at times on both Saturday and Sunday, with mostly cloudy skies and highs in the mid-40s to near 50. Saturday night lows bottom in the upper 30s to low 40s. Confidence: Low
