.DISCUSSION...
Issued at 237 PM CDT Wed Aug 19 2026
We issued the next Heat Advisory for our entire forecast area for
Thursday as high temperatures again will be in the middle to upper
90s, and when combined with surface dewpoints ranging from 73 to
77 degrees, maximum apparent temperatures (heat indices) should
range from 105-110 degrees. The same is expected for Friday, so
expected more Heat Advisories to come.
For the past couple of days we have seen convection develop inland
each afternoon and move southward, with many producing damaging
thunderstorm wind gusts. We expect the same for this afternoon,
and Thursday and Friday afternoons as we remain along the eastern
periphery of an upper ridge to our west with an upper trough
digging southward over the eastern CONUS. As daytime heating leads
to decreasing stability each afternoon, the environment will be
supportive of a few strong to marginal severe storms capable of
gusty surface winds, small hail, and frequent lightning as SBCAPE
values escalate to around 3,000 to 4,000j/kg. As a result, the
Storm Prediction Center has a Marginal Risk of severe weather
outlooked for our area today and Thursday. Friday is a wait and
see situation.
With the base of the upper trough reaching it's southernmost
extent (into the northeastern Gulf) by the weekend, this will
place our region in a deep northerly flow pattern, advecting in a
drier air mass with PWATs dipping below 1.5 inches. There is also
the potential for a surface boundary to enter our forecast area
over the weekend. While this won't have much affect on the ambient
temperatures, it should be enough to lower surface dewpoints and
heat indices to where advisories will not be needed. In addition,
there is a much lower chance of storms, so it is shaping up to be
a nice weekend.
The rip current risk gradually tapers as we head through the rest
of the week, with a moderate risk for the Florida Panhandle
becoming a low risk by Friday. A low risk will remain for the
Alabama coastline through the end of the week. /22
