Outlook to September 12August 20th, 2013 at 1:33 pm by Chad Evans under Chad's WLFI Weather Blog
Putting the latest forecast together, everything is on-track. The only change is the Thursday high temperature. I dropped it from 91 to 88 (from 88-92 to 86-90 for the viewing area) because the cold front is speeding up just a hair more & will come through likely in the mid-afternoon with a few storms possible at any point from morning to midday to afternoon. Coverage will run 30%.
Although it will still be warm to hot Friday-Sunday, the front will take the edge off the heat some & clean the air a tad.
However, it will head back up next week with 90s with the potential of the hottest air of the season just prior to Labor Day. A cold front will pass just prior to Labor Day with some storms.
After that (few severe storms cannot be ruled out, though nothing too widespread), it may cool off to overnight lows in the 50s & highs near 80 briefly.
However, it appears, it will still heat back up RAPIDLY. 90s are likely shortly thereafter with potential of an early- to mid-September heat wave. Temperatures may match the readings of late August to tie for the hottest weather so far this year.
A larger pattern shift may occur as we approach September 12 with some storms & a shot of cooler air.
