FORECAST IN DETAIL

Our trend of descending highs continues. From near 80 on Friday, to the low 60s yesterday, and down into the 50s today. But while we’re cooler than we have been ahead of this evening’s official start of spring (at 7:21 p.m. to be exact), at least we stay dry through the day. I say enjoy it while you can, since we head into a more unsettled pattern, with the potential for showers at times, tonight and through the better part of the week.

Today (Sunday): High pressure holds on long enough to keep us dry during the daylight hours, with plenty of sun shining through intermittent high clouds as a warm front approaches from the west. An onshore component to our light breezes means highs about 5-10 degrees cooler than yesterday, in the low-to-mid 50s. Confidence: Medium-High

Tonight: Clouds increase this evening as the warm front arrives, and a 20% chance of evening showers (before midnight or so) rises to about 60% overnight and toward morning. Any showers should be mainly light. Beneath mostly cloudy skies, overnight lows drop to the low 40s to near 40. Confidence: Medium

Tomorrow (Monday): A chance of showers, with an afternoon rumble of thunder not out of the question, continues. But any showers look to be on the light and sporadic side. We’ll be on the warm side of the warm front, so breezes from the south/southwest should get highs into the 60s. Confidence: Medium

Tomorrow night: Any showers likely come to an end during the evening hours for most of us, though they could linger a little later south of town. Mostly cloudy skies remain, with some fog/mist possible late night into early morning before winds from the west/northwest begin to dry us out. Lows drop to the mid-40s to near 50 in the suburbs, probably low 50s downtown. Confidence: Medium-High

A LOOK AHEAD

On Tuesday, we catch a bit of a lull in the action. We aren’t completely out of the woods though, as there may be just enough upper-level energy around to touch off a brief shower or two. But most of the day should be dry with at least partial sunshine and highs in the 60s. With the arrival of another warm front from the west, rain chances rise again late in the day and into the night, when a steadier moderate rain is possible. It doesn’t look like cold air lurking to the north will reach far enough south for frozen precipitation in the area, but we’ll keep watch in case things change. Confidence: Low-Medium

Decent shower chances may very well persist on Wednesday as low pressure moves by. Cloudy skies and a maritime flow off the Atlantic seem likely, which would result in a rather raw day with highs struggling to reach 50. But if the low ends up taking a more northerly track then we could be talking a little less clouds and more like 60 for highs. Confidence: Low
