It looks like another record will be broken today with a forecasted high of 104° (the record 101°, 1954).
As the upper level high that created the dry heat wave slowly slips southeastward, temperatures will start to back off to upper 90s Monday and Tuesday and mid 90s the rest of the week.
The humidity will be increasing, though, so the heat index will still be in the 100 degree range.
Also, we should begin to see the return of scattered summer like t'showers as the week goes on. These will not bring widespread rain each day, but if the trend continues, eventually each backyard or farm should see some rain.
The Climate Prediction Center's Drought Monitor has much of Middle TN in "Moderate Drought" conditions, and some areas in "Severe Drought".
Pray for the rain!
