DISCUSSION
(THIS EVENING THROUGH NEXT FRIDAY)
ISSUED AT 1250 PM CDT SAT JUN 27 2026
A FEW SPOTTY SHOWERS HAVE DEVELOPED ACROSS THE REGION THIS
AFTERNOON, HOWEVER AFTER MAX HEATING, CONVECTION WILL DISSIPATE.
A RIDGE ALOFT, AND AT THE SURFACE, STRETCHES ALONG THE NORTHERN
GULF COAST AND INTO THE ATLANTIC. THIS IS KEEPING THE REGION
MOSTLY PRECIP FREE (ASIDE FROM A FEW LIGHT DIURNAL SHOWERS). THE
PATTERN IS NOT ANTICIPATED TO CHANGE MUCH THROUGH TUESDAY. A FEW
MORE SHOWERS CAN BE ANTICIPATED SUNDAY AFTERNOON. HIGH
TEMPERATURES WILL BE NEAR TO SLIGHTLY ABOVE CLIMO NORMS. THIS WILL
PRODUCE THE TYPICAL DAYTIME HEAT INDICES OF 100 TO 107 IN THE
AFTERNOONS, HOWEVER, HIGH TEMPERATURES WILL GRADUALLY INCREASE
AROUND A DEGREE A DAY INTO TUESDAY, WHICH MAY PUSH INLAND AREAS TO
AROUND THE HEAT ADV CRITERIA OF 108. A SAHARAN DUST PLUME WILL
MOVE ACROSS THE REGION MONDAY AND TUESDAY WHICH MAY DECREASE THE
ALREADY MEAGER CHANCE OF RAIN AND MAKE CONDITIONS HAZY.
THE PATTERN IS FORECAST TO SHIFT FOR THE SECOND HALF OF THE WEEK
AND INTO THE HOLIDAY WEEKEND. THE RIDGE ALOFT IS FORECAST TO LIFT
NORTHEASTWARD ALLOWING TEMPERATURES TO MODERATE BACK TO CLIMO
NORMS AND FOR CONVECTION TO INCREASE.
