FORECAST IN DETAIL

We come to expect better and better weather as we get into May and average highs rise through the 70s (currently the low 70s). But today’s cool showers remind us that Mother Nature doesn’t always meet our expectations. Payback is a beauty of an afternoon tomorrow, followed by the return of shower chances Friday as the trend of alternating nice and unsettled days continues. What does that mean for Mother’s Day?...

Today (Wednesday): A band of showers, possibly some embedded thunder, moves through west to east during the morning and may linger along and/or east of I-95 into early afternoon, with the chance of an isolated shower thereafter. Temperatures are sharply cooler than yesterday, mainly in the 50s with cool 10-20 mph breezes (some higher gusts) from the northwest. Cloudy morning skies may show some afternoon breaks, which could briefly bump highs to near 60 or the low 60s. Confidence: Medium

Tonight: Can’t rule out a stray evening shower. Otherwise, lingering breezes keep things rather cool with lows in the low-to-mid 40s, possibly upper 30s in the coolest spots far north and west of town, under clearing skies. Confidence: Medium-High

Keep reading for the forecast through the weekend...

Tomorrow (Thursday): It’s a cool start for sure with morning temperatures rising through the 40s and 50s. But mostly sunny skies courtesy high pressure can’t be denied, boosting afternoon highs to around the mid-60s to near 70 with breezes from the northwest occasionally gusting to 20-30 mph. Confidence: High

Tomorrow night: High pressure hangs on long enough to provide mostly clear skies into the overnight, with the potential for increasing clouds toward morning and lows in the mid-40s to low 50s (suburbs to city). Confidence: Medium-High

A LOOK AHEAD

A dinky little upper-level system spells a 40% chance of mainly light showers and maybe an isolated thunderstorm Friday, with the shower/storm threat probably focused on the afternoon into evening rather than morning. Highs should manage the mid-60s to low 70s despite at least partly cloudy skies, followed by Friday night lows around the mid-40s to low 50s again. Confidence: Medium

Saturday shapes up as a more-than-decent start to the weekend with some sun and highs in the upper 60s to mid-70s. Clouds increase and shower chances return late Saturday and especially Sunday (Mother’s Day) along with a possible isolated t’storm. Temperatures stay seasonal with Saturday night lows near 50 to the mid-50s and Sunday highs again in the upper 60s to mid-70s. Confidence: Low-Medium
