KEY MESSAGES
ISSUED AT 604 AM CDT FRI AUG 7 2026
- HEAT: HUMIDITY WILL PUSH HEAT INDICES INTO THE 97-104 DEGREE
RANGE THIS WEEKEND INTO NEXT WEEK, RESULTING IN A MODERATE HEAT
RISK ACROSS CENTRAL ALABAMA.
DISCUSSION
(FRIDAY THROUGH NEXT THURSDAY)
ISSUED AT 1146 PM CDT THU AUG 6 2026
THIS EVENING, CENTRAL ALABAMA REMAINS IN A WEAK UPPER FLOW AREA
SOUTH OF THE MAIN BROAD TROUGH THAT EXTENDS OUT OF A CENTRAL
CANADA LOW AND DOWN INTO THE MID MS RIVER VALLEY. AT THE SAME
TIME, ALABAMA IS SITUATED BETWEEN TWO RIDGES, ONE ACROSS THE FOUR
CORNERS AND THE OTHER IN THE WESTERN ATLANTIC OFF OF THE VA/NC
COAST WITH ONLY MINOR PERTURBATIONS TRAVERSING THE WEAK FLOW
ACROSS CENTRAL ALABAMA. THIS HAS RESULTED IN TYPICAL SUMMERTIME
DIURNALLY ENHANCED CONVECTION, BUT THAT IS ALSO AT TIMES OUTFLOW
DRIVEN. BY MONDAY, THE WESTERN ATLANTIC RIDGE FLATTENS AND
RETROGRADES WESTWARD ACROSS THE NORTHERN GULF COAST. THE ONLY
DIFFERENCE FOR MONDAY ONWARD WILL BE THAT OF A SLIGHTLY DIFFERENT
ORIENTATION OF THE BETTER RAIN CHANCES FROM SHORTWAVE ACTIVITY,
BUT IT WOULD STILL BE DIURNALLY ENHANCED.
AS FOR TEMPERATURES, READINGS DO VARY A DEGREE OR SO HERE AND
THERE OVER THE NEXT WEEK WITH OVERALL MOISTURE REMAINING UP. THIS
WILL RESULT IN MAX AFTERNOON HEAT INDICES PERHAPS A COUPLE OF DEGREES
HIGHER IN SPOTS. HOWEVER, GUIDANCE CONTINUES TO KEEP US BELOW HEAT
ADVISORY CRITERIA FOR NOW.
