As we close out meteorological summer this holiday weekend, temperatures shouldn’t care too much about the “flip in the calendar.” In fact, our longest heat wave of this fairly tame warm season is possible after we get past today. Higher levels of humidity are on the way as well, along with an increased risk of showers and storms.

Today (Saturday): It’s not quite as nice as yesterday, but not terrible either. Partly sunny skies are likely, though that means shorter periods of cloudier or even mostly sunny are a good bet as well. Winds from the south around 5-10 mph send humidity back up as dew points head through the 60s. Mix in highs ranging from about 82-87, and you’ve got a pretty typical late August day. A very slight risk (10-20% chance) of a shower or storm may present itself, but that should mainly be confined to higher elevations west of the area. Confidence: Medium-High

Tonight: We’re staring down a summerlike evening and night. Humidity is in the solidly sticky range and temperatures won’t be in a hurry to fall. Under partly cloudy to occasionally mostly cloudy skies, plan on lows only reaching the near 70 to mid-70s range. Light south and southeast winds continue. Confidence: Medium-High

Tomorrow (Sunday): Clouds and rain have helped keep 90s away a number of times this year, and we may play that game again. Mostly to partly sunny skies in the morning should promote temperatures rising fairly rapidly into the 80s. As we get deeper into the afternoon, clouds become more numerous and at least scattered showers and storms are likely (60% chance) at times. Before any rain “cooled” air arrives, highs should rise to around 90 most spots. Any rain that falls may be heavy. Confidence: Medium

Tomorrow night: A risk of showers or storms persists into the evening, but that risk wanes around sunset. Otherwise, partly cloudy, muggy, and warm are the stories of the night. Lows again dip to near 70 in the suburbs to the mid-70s downtown. Confidence: Medium

A LOOK AHEAD

Labor Day Monday is the beginning of meteorological fall, though I’m guessing you won’t be feeling it if venturing outdoors for long. It’s a good pool day, with skies again averaging partly cloudy as highs rise to near 90 or the low 90s. A risk of late-day showers or storms should also arise again, but perhaps less widespread than Sunday. Confidence: Medium

Many get their shortened work week started on Tuesday, and there’s sure to be some sweating while waiting for the bus, walking to the metro, or the like. Coming off lows again in the 70-75 range, highs strive for near 90 or head into the low 90s. Under a partly cloudy regime, a late day shower or storm is possible. Confidence: Medium
