developing. Those showers will mature as they move east this
morning with some producing lightning. Further west, some isolated
to scattered storms will develop this afternoon. Shear is once
again weak, and PWAT values are back to 1.8-2" Storms will be
capable of heavy rainfall and an occasional wind gust to 40 mph.
Diurnal activity will decrease this evening with some patchy fog
after midnight. Monday will be similar with diurnal activity.
Today and Monday will see highs in the upper 80s to lower 90s. Dew
points will be in the low to mid 70s which will give us afternoon
heat index values in the upper 90s to lower 100s.

.AVIATION...
(18Z TAFS)
Issued at 1239 PM CDT Sun Jul 13 2025

At KBNA...afternoon showers and storms approaching from the west
today, so have included thunderstorm mention in forecast from
2000z through 0100z. Wouldn`t be surprised if we have a pop-up
earlier. Otherwise, light winds and no cig/vis restrictions
outside of storms. For other sites...afternoon showers and storms
expected in vicinity, if not impacting airports. Overnight, winds
diminish and could see some IFR vis due to fog at KSRB and KCSV.
Clouds should hamper fog development at KCKV and KSRB.
