FORECAST IN DETAIL

The sun is getting stronger, and the days are getting longer. Yet at least for this week, neither is translating into warmer weather. In fact, it continues to feel like the dead of winter today, with a particularly biting wind chill. We’re only a little warmer tomorrow, with a chance of light snow or rain Friday. Temperatures are moderate this weekend, but with a good chance of rain Saturday night into Sunday.

A LOOK AHEAD

A weak system brings the chance of light snow or rain on Friday. As of now the precipitation looks too light and temperatures too warm for any meaningful snow accumulation. But we can’t rule out a light grassy coating if it arrives early enough in the morning or lingers late enough in the evening, especially north and west. Friday highs top out near 40, with Friday night lows in the upper 20s to mid-30s. Confidence: Low-Medium

Saturday looks like the pick of the weekend, with partly sunny skies and highs in the mid-40s to near 50. Rain chances increase Saturday night, with lows in the mid-30s to near 40, as we spring forward an hour. And then rain is likely on Sunday. as a milder breeze from the south lifts highs to the mid-50s to low 60s. Confidence: Low-Medium

SNOW POTENTIAL INDEX

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

2/10 (): Right now a system moving through Friday looks too weak to muster any meaningful snow accumulation. But we can’t rule out a light grassy coating, especially north and west. We’ll keep our eye on it.
