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.

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

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.
