UPPER LEVEL RIDGING IS BEGINNING TO TAKE CONTROL OF THE REGION
LATE THIS EVENING. WATER VAPOR IMAGERY REVEALS THIS STOUT UPPER
LEVEL FEATURE EXPANDING EAST ACROSS MUCH OF THE SOUTHEASTERN US.
TO OUR SOUTH, AN AREA OF LOW PRESSURE OVER THE NORTHERN GULF WILL
CONTINUE TO MOVE WEST OVER THE NEXT COUPLE OF DAYS. THE NHC HAS
INCREASED DEVELOPMENT CHANCES TO 70% OVER THE NEXT 48 HOURS AS
THIS SYSTEM NEARS SOUTHWEST LOUISIANA/UPPER TEXAS COASTLINE. AS
WE HEAD THROUGH THE WORK WEEK, THE UPPER RIDGE WILL CONTINUE TO
EXPAND EAST. THIS WILL HELP TO STEER THE TROPICAL LOW TO THE WEST
ACROSS THE GULF. DRIER AIR AND INCREASED SUBSIDENCE WILL HELP
MAINTAIN RAIN-FREE CONDITIONS ACROSS THE NORTHERN HALF OF THE
AREA. WE LOOK TO CONTINUE WITH LOW CHANCES FOR DIURNALLY DRIVEN
CONVECTION ACROSS OUR SOUTHERN AREAS WHERE MOISTURE REMAINS
ELEVATED CLOSER TO THE COAST. AT THIS TIME, WE ARE NOT EXPECTING
MUCH IN THE WAY OF SEVERE WEATHER AS WIND SHEAR WILL BE MINIMAL.
HOWEVER, INSTABILITY WILL BE SUFFICIENT ENOUGH TO SUPPORT A
STRONGER STORM OR TWO AS WE REACH PEAK HEATING.
A WARMING TREND KICKS IN OVER THE COMING DAYS AS TEMPERATURES
CLIMB BACK INTO THE MID TO UPPER 90S BY MID WEEK. HUMID
CONDITIONS WILL PUSH HEAT INDICES INTO THE 105-108 RANGE EACH
AFTERNOON. DAILY HEAT ADVISORIES WILL LIKELY BE NEEDED BY TUESDAY
OR WEDNESDAY. OVERALL, THIS WILL PROMOTE A SIGNIFICANT HEAT RISK
FOR THE REGION. THE LATEST PROBABILISTIC HEAT RISK DATA SUGGESTS A
50-60% CHANCE OF A MAJOR OR HIGHER HEAT RISK AS WE HEAD INTO
LABOR DAY WEEKEND. HEAT SAFETY MESSAGING WILL BE RAMPED UP THROUGH
THE WEEK.
