Synopsis: Current surface map http://www.hpc.ncep.noaa.gov/sfc/awc90f.gif shows a cold front in the Central Plains moving slowly east. Summer-like heat and humidity will be experienced east of this front, including here in Tennessee, for the next several days until the front passes through on Thursday. This front will produce heavier thundershowers along its path followed by much cooler air as it moves slowly east this week.
This Week: Summer-like heat will continue Monday through Wednesday with highs in the middle to upper 80s each day. The aforementioned slow-moving cold front will combine with an upper-level trough digging through http://weather.unisys.com/gfs/gfs.php?inv=0&plot=500p®ion=us&t=3e to produce widespread showers and t-storms late Wednesday into Thursday. Strong to severe storms may develop in Middle TN during this time as well. The front will move through Thursday with clearing skies and much cooler air flowing in by Friday.
The Weekend: Temperatures will continue to be cooler-than-average through the weekend with highs in the 60s and lows in the 40s expected http://www.cpc.ncep.noaa.gov/products/predictions/610day/610temp.new.gif. A quick-moving disturbance may bring a few passing light showers on Saturday. Otherwise partly cloudy and cool conditions are expected this weekend.
Enjoy the rest of your day!
