By Ian Livingston

Cooler air inbound for late-week and weekend

A fair amount of cloudiness today has held temperatures in check, but humidity levels are back on the rise and into moderate levels. Afternoon readings are reaching the mid-and-upper 80s most spots, though a few 90+ can't be ruled out where sun breaks through a bit more. We've got a two-day return to higher heat and humidity upcoming before another cold front brings in some cooler Canadian air for the weekend.

Through Tonight: Skies should continue breaking a bit this evening before we head mostly clear late night. It will be mild and tranquil as temperatures reach the low-and-mid 80s around sunset. There could be a sprinkle or shower over the southern portion of the area, but don't count on it. Overnight lows dip to the upper 60s and lower 70s.

Tomorrow (Wednesday): If we had not already seen so much heat this summer I'd feel like complaining about Wednesday, but considering where we've been and what's ahead later in this week I'm going to take it in stride. Mostly sunny skies and increasingly high humidity levels work together to make highs in the low-and-mid 90s feel more like the upper 90s to near 100 across the area. I'm sure you all missed sweating profusely the last day or two.

Acuweather's 8/4-8/6 forecast hights (98, 98, 99) look really ugly. Enough stir fry already; put something else on the weather menu. Some chilly would be nice.

I wouldnt go that strong on heat in that time period just yet, there are conflicting signals around here. Main heat looks to be over the center of the country, we'll be on the line between heat and cooler air it seems.. though I don't doubt we'll see more heat in AUG with how this yr has gone.

What an amazing evening. I am ignoring upper 80s in the thermometer, and glad my acclimated body (from 100 degrees) can enjoy a rooftop evening!
