A daily assessment of the potential for *accumulating* snow for the next week on a 0-10 scale. More info


Today (Saturday): The day may average partly sunny, but sun should be more dominant than clouds. Those clouds tend to come in most consistently during the second half of the day, and start out mainly high-level without blocking all of the sun. Winds are back to the northwest with some gusts to about 15 mph. Highs rise to the upper 30s and lower 40s. Confidence: Medium-High

Tonight: Clouds increase and lower as a weak disturbance moves this way from the west. This system is small and doesn’t have much moisture to work with. Yet, a period of light snow and light rain showers may pass through (40% chance), potentially beginning as early as late evening and lasting possibly as late as pre-dawn. I-95 is again a decent marker locally, with places north and west seeing precip fall as snow, and those southeast more likely to be rain. At worst this event won’t even really count as a nuisance, with upside potential maybe a bit more than a dusting. It’s also possible nothing falls from the sky, given the paltry amounts expected. Lows range from the upper 20s to lower 30s. Confidence: Medium

Tomorrow (Sunday): The system quickly departs, and its clouds should break by the early morning if not prior. More energy passing to the north may keep us from being totally clear through the day though, so expect some periods of cloudier skies. Overall, not too shabby. Highs should average about the mid-40s. Confidence: Medium-High

Tomorrow night: Partly cloudy skies are the rule, though another disturbance passing by in the upper levels might bring mostly cloudy conditions surrounding midnight. It’s a somewhat potent upper-system, so it wouldn’t be shocking if a few late-night snowflakes or rain drops fell either. Lows are in the upper 20s to lower 30s. Confidence: Medium-High


Monday is tickled by sunshine from start to finish. At least take a few ganders out the window if not a stroll for lunch. It may be a bit breezy at times, as high and low pressure around us bump up against each other. Afternoon temps should reach the low-to-mid 40s and overnight lows range from the mid-20s to near 30. Confidence: Medium

Tuesday brings us more sunshine and an air mass that is modifying. We might kick off the noticeable warming trend, which continues through much of the week, but I think it’ll start kind of muted. Again we shoot for the low-and-mid 40s, though probably on the high side compared to Monday. Confidence: Medium
