FORECAST IN DETAIL


Even though we’re into meteorological spring, this should be a rather wintry feeling weekend. Quite the difference from a year ago, which helps highlight the variability in the month’s weather. The next few days are worry free, which gives plenty of time to ponder what might be lurking beyond. Whether you’re excited about the midweek snow chance or tired of it all at this point, just remember the clock is soon to run out.

Today (Saturday): Today is sort of like a repeat of yesterday, but perhaps a touch cooler and — if we’re lucky — less cloudy. Cold air aloft will still want to promote cloudiness though, so I wouldn’t expect tons of sun. High temperatures shoot for the low-to-mid 40s or thereabouts. Winds are from the northwest around 10 mph with higher gusts. Can’t rule out a flurry or sprinkle, but don’t expect much! Confidence: Medium-High

Tonight: A flurry may float by during the evening. Mostly to partly cloudy skies persist, though we should see increasing breaks in the overcast as the night wears on. Lows dip to the mid-20s in the cold spots to around 30 downtown. Confidence: Medium-High

Tomorrow (Sunday): Sunshine is probably a little more prominent again, leaving us generally partly cloudy. Temperatures might also be a little cooler than today, with highs mostly reaching near 40 to the mid-40s. Winds from the northwest continue around 10 to 15 mph with higher gusts. Confidence: Medium-High

Tomorrow night: As the pattern remains a bit stagnant, we’re looking at more of the same — skies trending clearer overnight, and chilly temps. Lows might dip a bit further than tonight with more clear skies, ranging from about 22-29. Confidence: Medium-High

A LOOK AHEAD

On Monday, we should get a really solid dose of sunshine as it seems to be quite prevalent through the day. It’s still breezy with us sandwiched in between weather systems, but maybe a touch less so than over the weekend. Highs head for the mid-40s or so. Confidence: Medium

Tuesday starts the turn toward trickier weather conditions, though the day itself could be largely dry. A system dropping southeast from the central United States may throw some clouds over the area especially late in the day, and even some light precipitation in the form of snow or rain showers. Depending on the timing of the clouds associated with our potential storminess, highs range from the mid-40s to near 50. Confidence: Low-Medium

The storm potential for Wednesday remains uncertain. We could see a strong coastal storm develop, but it fulfilling the potential is still highly in question. If the storm does develop and move up the coast, precipitation (more snow than rain, though surface temps might be “mild” in spots) increases by daybreak and may continue through the day. If the development is too late, we end up dry or just with scattered showers (snow or rain). Last night’s models were mixed, and less impressive locally than during the day yesterday overall, but the sum of all recent guidance still suggests that snow is a very real possibility. Confidence: Low

We’ll have a storm update by mid-afternoon.
