Our cool Memorial Day weather regime is history thanks to the warm front which boosted temperatures into the low 80s this afternoon. After a few widely scattered thunderstorms this evening, we settle into a very warm, muggy weather regime to last through the weekend.

Through Tonight:  Hit or miss thunderstorms (30 percent chance) will rapidly zip through the region this evening, with most activity before 9 p.m.  A few storms could produce brief downpours and strong winds gusts.  Then, it’s tranquil and mild.  Under a soft breeze from the south, lows range from the low 60s in the cooler suburbs to near 70 downtown.

Tomorrow (Wednesday): Mostly sunny and hot…perhaps the hottest day of the summer so far.  Highs climb into the low 90s, with winds from the southwest at 5-15 mph.  Humidity levels are moderate-to-high, not quite in the oppressive range.

Pollen: Tree counts are MODERATE, grasses HIGH, weeds LOW, and mold LOW-MODERATE.
