The mercury rocketed to 100 degrees today on the first day of "Meteorological Fall" (September, October and November)!  This was our hottest day this year and the first time we have hit 100 degrees since August 13, 2010.

Even though Louisville hit 100 it was still three degrees shy of our record for today (103/1953).  Today was also the hottest September day in 57 years!  On September 5, 1954 the mercury climbed to 104 degrees (the all-time High for September).

The weather models are showing 850mb temperatures around 22.2 degrees Celsius both on Friday and Saturday.  Temps that warm at 850mb can easily support highs in the triple digits!

GFS (Friday Evening) 850mb temp: 22.2C...  Will produce a High of 101

 

GFS (Saturday Evening) 850mb temp: 22C...  Will produce a near 100

There is relief in site...  The GFS model brings a front through the region Sunday with scattered showers and storms.  Temperatures will fall to near 90 on Sunday and then to the upper 70s on Labor Day as a cool ridge of high pressure builds into the region from Canada.  Stay cool until then!!
