702 PM CDT Mon Jul 27 2026

...New UPDATE, AVIATION...

.KEY MESSAGES...
Updated at 701 PM CDT Mon Jul 27 2026
 
  - Dangerous heat continues areawide. Heat Advisories are in
    effect through Tuesday and an Extreme Heat Warning goes into 
    effect for our coastal areas on Tuesday.

  - A High Risk of rip currents is expected to return midweek for
    our Florida beaches.

  - Daily afternoon and evening scattered thunderstorm chances
    increase in the middle to latter part of the week.

&&

.UPDATE...
Issued at 701 PM CDT Mon Jul 27 2026

Isolated showers and thunderstorms continue to develop as of early 
evening as they move south, particularly as outflow interacts with 
the Mobile Bay breeze. This activity is expected to diminish within 
the next few hours with the loss of daytime heating. JGC/98

&&

.DISCUSSION...
Issued at 1156 AM CDT Mon Jul 27 2026

Very hot and humid conditions will persist across the area through
at least mid week. High temperatures will top out in the upper
90's to near 100 Tuesday, with heat indices near 110 over interior
portions of the area while areas nearer the coast may see heat
indices locally up to 115. This in combination with very warm
overnight temperatures in the middle to upper 70's will result in
significant heat stress for any individuals spending prolonged
periods of time outside or have limited access to air conditioning.
Given the potential for heat indices up to 115, we have opted to 
go with an Extreme Heat Warning for coastal portions of 
Mobile/Baldwin counties eastward through coastal Escambia, Santa 
Rosa, and Okaloosa counties Tuesday. Elsewhere, a Heat Advisory 
will be in effect Tuesday for heat indices to near 110. Drink 
plenty of fluids and limit time outdoors if possible by taking 
frequent breaks! We will have to contend with at least one more
day of high heat indices Wednesday, particularly across the
western half of the area as heat indices once again rise to near
110. Additional heat advisories will likely be needed as we move
forward in time.

As we head into mid to late week temperatures and heat indices 
will begin to relax some as upper ridging shifts west and we get 
upper troughing to begin influencing the area. This will in turn 
bring a much wetter pattern to the area with scattered to numerous
showers and thunderstorms possible, particularly as we head into 
late week and the weekend. While it's difficult to pinpoint any 
particular day for elevated chances for strong to severe storms, 
the potential for locally damaging wind gusts associated with any 
microbursts will exist each afternoon in addition to brief, heavy 
rainfall and frequent lightning in storms.

Persistent westerly flow across the marine waters will help to
build surf and swell which will likely cause issues with rip 
currents. A low risk for rip currents across the Alabama coast 
today and Tuesday becomes a Moderate risk Wednesday through 
Friday. Likewise, a Moderate risk of rip currents today and 
tomorrow becomes a High risk Wednesday through Friday.  MM/25

.AVIATION...
(00Z TAFS)
Issued at 701 PM CDT Mon Jul 27 2026

Generally VFR conditions are expected to prevail through the period. 
Isolated showers and storms will gradually diminish through the 
evening hours, but could still cause brief drops in visbys to MVFR 
or lower and brief gusty winds. A 10-20% chance of a shower or storm 
also exists over coastal counties Tuesday afternoon. Winds will be 
mainly light and variable tonight, becoming northwesterly around 5-
10 knots in the morning and turning southwesterly near the coast 
with the sea breeze in the afternoon. JGC/98

&&

.MARINE...
Issued at 1156 AM CDT Mon Jul 27 2026

A diurnal wind pattern is expected early in the week with a light to 
moderate northwesterly flow early each morning turning westerly to 
occasionally southwesterly through the afternoon and evening. Light 
to moderate westerly flow becomes established the latter half of the 
week. Storm coverage will increase by mid week with winds and waves 
locally higher near any storms. Small craft should exercise
caution over the gulf through much of the week. MM/25
