A 500MB RIDGE IS CENTERED OVER WEST TX AND NM. THE RIDGE IS
STRENGTHENING AND BROADENING ITS SCOPE TODAY, WITH SOME SUBTLE
HEIGHT RISES OVER THE REGION. AT THE SURFACE, A STATIONARY FRONT
IS DRAPED FROM THE SOUTHEAST TO THE ARKLATEX TO CENTRAL OK.
MOISTURE IS POOLED ON THE NORTH/EAST SIDE OF THE BOUNDARY ACROSS
EASTERN OK AND NW AR. AS OF NOON, SEVERAL SITES ARE ALREADY
HITTING ADVISORY CRITERIA HEAT, AND WE ARE HEADING FOR ANOTHER
DAY OF WARNING LEVEL HEAT ACROSS A GOOD PORTION OF EASTERN OK AS
THE MID LEVEL CLOUD COVER FROM THIS MORNING FADES.
MODEL DATA SUGGESTS LESS CONVECTIVE COVERAGE THIS AFTERNOON AND
EVENING COMPARED TO YESTERDAY, POSSIBLY BECAUSE OF THE RISING MID
LEVEL HEIGHTS ALOFT. NEVERTHELESS, EXPECT ISOLATED TO WIDELY
SCATTERED AFTERNOON SHOWERS AND STORMS MAINLY OVER FAR EASTERN OK
INTO WESTERN AR THAT SHOULD GO AWAY AFTER SUNSET THIS EVENING.
LIKE YESTERDAY, SLOW-MOVING STORMS IN A HIGH PWAT ENVIRONMENT
(WITHIN THE JUICY FRONTAL ZONE REGION) COULD DROP LOCALLY HEAVY
RAINFALL.
A SHORTWAVE TROUGH NOTED IN SATELLITE IMAGERY AND RAP ANALYSIS IS
TOPPING THE RIDGE OVER WY/MT CURRENTLY AND IS EXPECTED TO MAKE A
TURN TOWARD THE SOUTHEAST TONIGHT. LIFT AHEAD OF THE SYSTEM IS
EXPECTED TO FORCE A SOUTHEASTWARD ADVANCING MCS TONIGHT ACROSS THE
CENTRAL PLAINS. A BAND OF ELEVATED SHOWERS AND STORMS OVER KS MAY
DROP DOWN INTO NE OK BY DAYBREAK FRIDAY.

THE AFOREMENTIONED SHORTWAVE TROUGH WILL STRENGTHEN AS IT HEADS
SOUTHEAST OVER THE PLAINS FRIDAY INTO SATURDAY, AS THE 500MB RIDGE
CENTER SHIFTS WEST TO THE DESERT SOUTHWEST. THE BAND OF ELEVATED
SHOWERS AND STORMS DURING THE MORNING AHEAD OF THE SYSTEM WILL
GRADUALLY FADE AS IT HEADS SOUTHEAST ACROSS THE REGION. BY
AFTERNOON, THE SURFACE COOL FRONT WILL BE DROPPING SOUTH INTO NE
OK AND FAR NW AR AND WILL CONTINUE SOUTH ACROSS THE REMAINDER OF
THE FORECAST AREA FRIDAY NIGHT. AHEAD OF THE FRONT, ANOTHER DAY OF
HEADLINE LEVEL HEAT IS EXPECTED, WHILE SOME UNCERTAINTIES DUE TO
CLOUD COVER AND FRONTAL TIMING REMAIN, ESPECIALLY ACROSS THE
NORTH. MODELS SHOW POTENTIAL FOR ISOLATED TO SCATTERED STORMS
ALONG THE FRONT LATE IN THE DAY AND INTO THE EVENING. DEEP LAYER
SHEAR IS NOT PARTICULARLY STRONG OVER OUR AREA, BUT IMPROVES
CLOSER TO THE SURFACE AND UPPER LOW TRACK OVER MO. THUS, SEVERE
POTENTIAL LOOKS PRETTY LOW.
RELATIVELY COOLER AND DRIER AIR WILL FILTER INTO THE REGION
BEHIND THE FRONT, YIELDING A MULTI-DAY BREAK FROM THE OPPRESSIVE
HEAT FOR THE WEEKEND INTO MONDAY.
RIDGING ALOFT WILL EVENTUALLY BUILD BACK OVER THE SOUTHERN CONUS
LATER IN THE WEEK, AND SOUTHERLY WINDS WILL RETURN ALONG WITH
GRADUALLY INCREASING HUMIDITY. HIGHS ARE EXPECTED TO APPROACH
TRIPLE DIGITS BY THE LATTER PART OF NEXT WEEK IN SOME AREAS. THE
FORECAST LOOKS DRY FOR MOST AREAS, WITH POSSIBLY SOME LOW CHANCES
RETURNING FOR MID TO LATE WEEK IN THE TERRAIN OF SE OK AND NW AR.
