Much of this summer has brought us bouts with unusually cool and not-so-humid conditions. The season’s final weekend, however, bucks that trend as very warm and humid air sets up shop through Labor Day. Thankfully, the heat won’t be too intense. But the chance of a shower or storm interrupting our outdoor activities, even if only briefly, does steadily increase each day through Monday.

Today (Saturday): Just about what you’d expect for the last day of August. Partly sunny skies lift morning temperatures steadily through the 70s and into the 80s. Afternoon highs reach the rather warm upper 80s to near 90, while a breeze near 10 mph from the south keeps humidity up in the moderate to high range. Any afternoon storms?… about a 30% chance. Confidence: Medium-High

Tonight: A pretty typical summer evening with a 30% chance of an evening storm, then just partly to mostly cloudy overnight. And muggy, too, with lows in the upper 60s to low 70s. Confidence: Medium-High

Tomorrow (Sunday): Looks like we’ll dial up another day similar to today, with partly sunny skies and highs headed back for the upper 80s to near 90. The humidity is high and afternoon shower and storm chances increase a bit to 40%, but still we may be looking at a hit-or-miss situation rather than surefire soaking. Confidence: Medium

Tomorrow night: Sunday night shapes up as partly to mostly cloudy with a 30% chance of a shower or storm. Muggy lows are mainly in the low-to-mid 70s. Confidence: Medium


The beat goes on by the time we get to Labor Day, with highs making another run at the upper 80s to near 90 and the humidity locked in place. An approaching cold front pushes the chance for showers and storms up another notch to 50%. Can’t say much about timing yet, but it doesn’t look like an all-day washout. The storm threat extends into Monday evening as lows tend toward the mild side again, in the low-to-mid 70s. Confidence: Low-Medium

There’s a chance the cold front clears the area in time for a partly to mostly sunny Tuesday with little to no chance of rain. But at this point there’s just as good a chance the front gets hung up a bit, leaving us with a partly cloudy day and the potential for a few showers or thundershowers. Highs head for the 80s with the humidity hopefully starting to lose its grip. Confidence: Low-Medium
