This might have been the last hot day until spring. Or not. But it’s definitely one of the last. That’s a good thing, since temperatures in the upper 80s to near 90 are unquestionably getting stale. Cooler air is a longtime coming, and we may see more than one day of cooler than normal readings in the week ahead. It all gets underway tomorrow.

Through tonight: Warm late-afternoon and early evening conditions are on the way, but it’s not super humid, so temperatures should cool into the 70s quickly with sunset. Skies are clear most of the night as a front moves this way from the north. The front should pass through between midnight and shortly after sunrise. There could be some increased cloudiness with the front, or behind it. Lows range across the 60s, from near 60 in the coolest suburbs to the upper 60s downtown. Winds are light and shifting to the north.

Tomorrow (Saturday): We might see some periodic cloudiness behind the front, but the overall winner should be sunshine when the day is said and done. Cooler air is trickling in throughout, which keeps temperatures from rising too fast. Upper 70s to near 80 should do it. Winds are from the north and slowly shifting to the northeast, around 5 to 10 mph.

Sunday: Coming off lows mainly in the 50s (a few upper 40s well north and west?), Sunday is very much a real taste of fall. Skies are mostly sunny, and temperatures may even be below normal for a change. That equals highs mainly in the near 70 to mid-70s zone. Winds should be light. A great day to get outside!
