...TSRA POTENTIAL THE NEXT 24 HRS IS THE MAIN CONCERN...

SMALL...BUT RELATIVELY POTENT...BATCH OF TSRAS PRODUCED SVR WX ACROSS
THE MIDDLE OF CWA THIS MORNING. THIS CLUSTER EFFECTIVELY PUSHED INVERTED
SFC TROF SOUTH TO NEAR THE NEB/KS BORDER...AT LEAST IN OUR CWA. FURTHER
SOUTH...WARM FRONT IS LIFTING THRU CNTRL KS W/ M60 DWPTS AS FAR NORTH AS
TOP/SLN. PLENTY OF TSRA ACTIVITY IN WARM SECTOR IN ERN KS...W/ WEAKER
RETURNS INTO OUR 6 NC CNTYS. AS WARM LIFTS INTO INVERTED TROF...EXPECT
TSRAS TO BECOME MORE WIDESPREAD LATE THIS AFTN INTO EVENING. THE BEST
POTENTIAL FOR SVR WX WILL BE OVER NC KS...BUT WILL ALSO WORK NORTH THRU
NEB CNTYS AS STRONG OVERRUNNING OF COOL SFC AIR TAKES PLACE TONIGHT W/
THE APPROACH OF POTENT UPPER LVL SYS CURRENTLY INDICATED CLEARING ON WV
IN AZ. EVENTUALLY EXPECT COOL LLVL AIR TO BE DISPLACED NORTH AS WELL
OVER MOST OF CWA.

WILL FOLLOW ETA W/ ITS SLIGHTLY BETTER HANDING OF LLVL MOISTURE INFLUX
W/ THE CAVIOT THAT IT DID NOT ANTICIPATE THE SWRD PUSH OF SFC TROF BY
AM TSRAS. REALLY...FCST PLAYS OUT ABOUT THE SAME USING ALL THE MDLS W/
BASIC SCENARIO OF TSRAS INCREASING IN COVERAGE THRU NC KS THIS AFTN &
SPREADING THRU NEB CNTYS THIS EVENING...SOME DRY SLOTTING OVERNIGHT...
THEN THE UPPER LO LIFTS NE OVER CWA TOMR...W/ POTENTIAL FOR SVR WX...
INCLUDING TORNADOS INTO EARLY AFTN...WHEN SYS PASSES NE AND A STRONG W
TO NW WIND DRIES THINGS OUT. WHEN ALL THINGS ARE SAID AND DONE...ONLY
NEED TO TWEEK CURRENT FCST. WILL HAVE TO REWORD TEMPS TONIGHT AS 40S
IN PLACE OVER MUCH OF NRN/CNTRL CWA WILL BE REPLACED BY 50S TONIGHT.
WILL UP TEMPS TOMR AS WELL...ESP SE 1/2 OF CWA BASED ON PROGGED TRACK
OF SFC LO AND SOUTH WINDS FCST THRU EARLY AFTN.

AS FOR EXTENDED...WONT PLAY W/ MUCH. AS PER PMDEPD...SOME DIFFICULTY
W/ NEXT WAVE THAT DROPS IN BEHIND CURRENT SYS. I AM INCLINED TO LEAVE
FCST DRY. I EXPECT 2ND SYS TO HAVE ALOT OF TROUBLE MAINTAINING ITSELF
AS IT WORKS EAST INTO CONFLUENT FLOW LEFT IN BEHIND CURRENT BIG STORM.
OTHERWISE...A TREND TOWARD WARMER WX BY WEEKEND AFTER COOLER READINGS
INVADE LATE WED INTO THU IN WAKE OF AZ UPPER LO.
