HIGH PRESSURE REMAINS IN COMMAND OF THE FORECAST AT THIS HOUR.
RAP ANALYSIS PLACES A WIDE BERTHING UPPER HIGH RIDGE SPANNING THE
ENTIRE SOUTH-CENTRAL CONUS. CLOSER TO THE SURFACE, A SFC HIGH
RIDGE EXPANDS OUTWARDS FROM FLORIDA, THE CREST OF ITS WESTERN
EXTENT SITUATED OVERTOP EAST TEXAS AND WEST LOUISIANA. THIS SFC
FEATURE KEEPS A SOUTHERLY WIND WHILE THE UPPER RIDGE HELPS TO
KEEP THE AREA CAPPED; THE FORECAST IS NIL OF RAIN CHANCES AND
ULTIMATELY, HOT. DRY DUST CAN BE SEEN IN THE REGION AS A GREENISH
HAZE ON DAY CLOUD IMAGERY; IT DOESN'T SHOW UP SO WELL ON NIGHT
TIME IMAGERY, BUT WE KNOW IT'S THERE!
THE UPPER RIDGE AND DRY DUST WILL MAKE FOR HOT, MIXED DAYS FROM
TODAY THROUGH THE WEEKEND. THANKFULLY AS THE SFC HIGH BOUNDARY IS
SITUATED OVERHEAD, IT GENERATES A DAILY DIURNAL PRESSURE GRADIENT
OFF THE SURFACE BETWEEN ITSELF AND ANY LOW PRESSURE FORMING IN THE
CENTRAL US. THIS GRADIENT INDUCED-WIND GETS MIXED TO THE SFC AND
THUS, WE HAVE OUR DAYTIME BREEZE.
THUSLY AND THEREFORE, EXPECT DAYS WITH HIGHS IN THE 90S, HEAT
INDICES IN THE 100 TO 105F RANGE, AND BREEZY SOUTHERLY WINDS OVER
THE WEEKEND. THE NEXT APPRECIABLE RAIN CHANCE RETURNS TO THE
FORECAST ON TUESDAY WHEN AN UPPER TROF LOOKS TO CHALLENGE THE HIGH
PRESSURE REGIME OVERHEAD.
