FORECAST IN DETAIL

The nice thing about this summer’s bursts of high heat is they’ve been relatively short-lived, with substantial stretches of kinder and gentler heat (i.e., cooler and less humid) in between. After yesterday’s sizzler, temperatures are on their way down once again, although not really noticeably so until tomorrow, when both temperatures and humidity should be about as pleasant as can be this time of year.

Today (Wednesday): A cold front moving south and east of the area means a nice breeze (10-15 mph at times) from the northwest. That means a touch cooler and gradually less humid weather than the past couple of days, but still moderately humid and very warm with partly to mostly sunny skies and highs in the low-to-mid 90s. The front may linger close enough for a 30% chance of a few afternoon or early-evening storms. Confidence: Medium-High

Tonight: After a 30% chance of an early-evening storm, skies go mostly clear and the air turns noticeably less humid as lows dip into the 60s. Confidence: Medium-High

Keep reading for the forecast through the weekend...

Tomorrow (Thursday): A light breeze from the north and northeast, circulating around high pressure centered near the Great Lakes, brings a more significant cool down and much lower humidity. The result is a pretty fantastic mid-July day with mostly sunny skies and highs in the mid-to-upper 80s. Confidence: High

Tomorrow night: A cooler day sets the stage for a comfortable night by July standards. Mugginess is still missing in action and lows drop to the 60s again under partly to mostly clear skies. Confidence: High

A LOOK AHEAD

As high pressure moves offshore Friday, humidity begins to rise again and a 30% chance of isolated to scattered storms is back come Friday afternoon and/or night. Temperatures remain pleasant with partly sunny skies and highs in the 80s, followed by Friday night lows in the mid-60s to near 70. Confidence: Medium

The weekend won’t be terribly hot, but not exactly refreshing either. Skies are probably partly sunny with highs in the 80s to near 90. Moderate humidity and low pressure trying to develop to the south mean a 20-30% chance of mainly afternoon/evening storms. Not a high enough chance (in my opinion) to be changing any plans at this point, and it may turn out that the focus of any storms is west toward the mountains. But do check back as we get closer. Confidence: Medium
