DISCUSSION...
ADDITIONAL RAIN BANDS WITH EMBEDDED THUNDERSTORMS WILL LIKELY
SPREAD NORTH TODAY AND WILL THEREFORE EXTEND IN TIME THE CURRENT
FLASH FLOOD WATCH UNTIL 700 PM THIS EVENING. ALTHOUGH RAINFALL
AMOUNTS WILL BE MUCH LESS THAN YESTERDAY...FLASH FLOOD GUIDANCE
REMAINS LOW AND TAKING INTO ACCOUNT THE ONGOING FLOODING
CONDITIONS...KEEPING THE WATCH SEEMS WARRANTED. RAINFALL AMOUNTS
AROUND AN INCH WITH LOCALLY TWO INCHES WILL BE POSSIBLE THROUGH
THIS EVENING BEFORE PRECIPITATION BEGINS TO SHIFT EAST.

UPPER LOW WILL MOVE VERY SLOWLY NORTHEAST TODAY WITH THE CIRCULATION
CENTER LIFTING INTO OKLAHOMA ON THURSDAY. STILL EXPECT SHOWERS WITH A
FEW EMBEDDED THUNDERSTORMS TO DEVELOP WITH MODEST SURFACE HEATING
THURSDAY AFTERNOON. THE STRONGER STORMS COULD PRODUCE HAIL GIVEN
THE STEEP MID LEVEL LAPSE RATES/COLD TEMPERATURES ALOFT. DEEP
LAYER SHEAR WILL ALSO INCREASE ACROSS SOUTHEAST OKLAHOMA AND WEST
CENTRAL ARKANSAS BY THIS TIME...SO A FEW SEVERE STORMS ARE STILL
NOT OUT OF THE QUESTION.

UPPER LOW WILL SHIFT NORTHEAST OF THE AREA BY THIS WEEKEND WITH A
SLOW WARMING TREND INTO THE EARLY PART OF NEXT WEEK AS UPPER RIDGE
BUILDS OVER THE SOUTHERN PLAINS. WEAK FRONTAL BOUNDARY TRIES TO
PUSH INTO SOUTHERN KANSAS BY TUESDAY WITH THE POTENTIAL FOR
INCREASING CHANCES OF SHOWERS/THUNDERSTORMS. KEPT THE EXTENDED

OF THE AREA DURING THIS TIME.

THE HEAVIEST RAIN FALL HAS FINALLY PUSHED EAST OF THE AREA THIS MORNING.
THE UPPER LEVEL LOW CURRENTLY OVER TEXAS WILL SLOWLY BEGIN TO LIFT

EXTENDED DISCUSSION...

SIMILAR CONDITIONS ARE EXPECTED AGAIN ON THURSDAY AS STEEP LAPSE
RATES WILL RESULT IN SUFFICIENT INSTABILITY FOR A FEW STORMS
TO PRODUCE LARGE HAIL. ONCE THIS SYSTEM CLEARS THE REGION...UPPER

WEATHER IS EXPECTED FOR THE WEEKEND...AND INTO NEXT WEEK.
