NOW: Cooler days and chilly nights arrive for the start of fall

NEXT:

After reaching 80° for the 12th time this month on Tuesday, today is our transition day as temps fall back to cooler levels to start astronomical fall. We started out mild and humid this morning, but lower dew points are pushing in from the northwest with all of southeast WI dropping to comfortable levels by this afternoon. 

With a cooler, drier airmass settling in, Milwaukee will likely drop cooler than 55° tonight for the first time since June 19th. 94 straight nights warmer than 55° is Milwaukee's 5th longest stretch on record.

It'll feel crisp tonight with lows in the upper 40s to low 50s, but it'll feel downright chilly come Friday morning as we all drop well into the 40s. A few inland spots may even drop into the upper 30s! 

Not only will be be on the cooler side at night, it'll also be much cooler during the day. Temps only rise into the low to mid 60s for highs to end the work week. We'll briefly warm up to normal on Saturday before dropping back into the 60s again to start next week.

Are we done with the summer heat for good? Never say never. September 29th is the average day of our last 80° day. The 8 to 14 day temperature outlook taking us through the end of September and start of October shows a 40-50% chance for above average temps. By then our average high will have dropped into the upper 60s.
