.DISCUSSION...
STAGE STILL APPEARS TO BE SETTING UP FOR A VERY BUSY FEW DAYS
WRT SEVERE WEATHER ACROSS OKLAHOMA AND WESTERN NORTH TEXAS. LARGE
SCALE WESTERN TROUGH WILL BRING SEVERAL SHORTWAVES INTO THE
SOUTHERN PLAINS THROUGH TUESDAY BEFORE MAIN TROUGH MOVES THROUGH.

FOR TODAY... CAPPING INVERSION HAS HELD THINGS IN CHECK... BUT
MIDDAY SOUNDING ACROSS THE AREA SHOW ONLY MINIMAL CAP STILL
REMAINING. EXPECT STORMS TO DEVELOP ACROSS WESTERN OKLAHOMA INTO
WESTERN NORTH TEXAS AND WITH EXTREME INSTABILITY AND STRENGTHENING
WIND FIELDS... SEVERE STORMS ARE LIKELY.

ANOTHER ROUND OF SEVERE WEATHER IS ANTICIPATED ON SUNDAY WITH THE
MAIN SFC BOUNDARIES RESIDING FARTHER EAST AND SOUTHEAST IN THE
MAIN BODY OF THE STATE WITH AFTN STORMS DEVELOPING IN WESTERN
OKLAHOMA AND MORE LIKELY AFFECTING CENTRAL SECTIONS OF
OKLAHOMA. AGAIN INSTABILITY AND WIND FIELDS WILL BE VERY
FAVORABLE FOR HIGH END SEVERE STORMS.

THE LATEST MODEL RUNS HAVE SLOWED THE EASTWARD PROGRESSION OF SFC
BOUNDARIES DOWN AND KEEP MUCH OF CENTRAL INTO EASTERN OKLAHOMA IN
THE RISK ON MONDAY AND PERHAPS EVEN INTO TUESDAY ACROSS SOUTHEAST
OKLAHOMA. THE PARTICULARS WILL BECOME INCREASINGLY DEPENDENT ON
WHAT HAPPENS THE DAY/NIGHT BEFORE.

OTHERWISE VERY WARM/HOT AND MUGGY CONDITIONS WILL CONTINUE THE
NEXT SEVERAL DAYS BEFORE THE SFC FRONT WORKS THROUGH THE AREA WITH
SOME COOLER AND DRIER AIR WORKING INTO OKLAHOMA AND NORTH TEXAS.
