...TIMING/PLACING TSRA CHCS BIG CHALLENGE AS ACTIVE PAC FLOW CONTS...

UAA THIS AM 100-125KT H3 JET FROM ID TO MN. WE COME UNDER RRQ OF THIS
JET TNGT-THU. IN THE H5-H7 LAYER...WARM DOME CURRENTLY POISED OVER &
S OF CWA. HWVR...COOLER TEMPS ADVTG IN FROM NRN CO & WY. MEANWHILE...
H85 FRONT STALLED NEAR NEB/KS BORDER W/ 8-10 DEG DWPTS POOLED ON IT.

AT THE SFC...EARLY AFTN CHART HAD STALLED BOUNDARY NEAR NEB/KS BORDER
W/ 70 DWPTS POOLING ALONG & S OF IT. INTERESTING FEATURE...BASICALLY
A COOL FRONT ALONG LEADING EDGE OF STRONG WESTERLIES HAS PUSHED INTO
S CO & NW KS...W/ NORTHEAST EXTENT OF THIS INTO WRN/NRN CWA. APPEARS
THIS WILL BE THE FOCUS FOR LATE AFTN/EVE TSRAS. CAP WL BREAK TODAY.
IN FACT IT ALREADY HAS IN WRN KS. TSRAS SHOULD FIRE IN THIS AREA IN
A FEW HRS & PROBABLY INCREASE IN COVERAGE AS BOUNDARY SHIFTS SE INTO
OTHER WASHED OUT FRONT & RICHER DWPTS FROM NEB/KS BORDER SOUTH.

OTHERWISE...MAIN COLD FRONT MOVING INTO NRN WY/WRN ND W/ THE USUAL
PRE-FRONTAL TROF FROM WRN SD INTO THE NEB PNDHL. THESE FEATURES MAY
STILL FOCUS SOME TSRAS...BUT IT APPEARS MOISTURE WL REMAIN LARGELY
CUTOFF...ONCE TSRAS FIRE ON SRN BOUNDARIES. WL HIT SRN AREAS HARDEST
W/ ONLY A 20/30% IN THE NORTH.

INTO THU...COLD AIR CONTS TO SLIP INTO CWA BEHIND FRONT...WHICH WILL
CLEAR KS BY 00Z. WV IMAGERY SHOWS UPPER TROF EXTENDING FROM WRN US
INTO THE PACIFIC. THIS SUPPORTS MDLS IDEA OF POSTFRONTAL PCPN TO AT
LEAST SRN PARTS OF CWA...AS ENERGY OVERRIDES COOL LLVL AIR. AGAIN...
WL WORD SRN ZONES W/ BETTER CHCS. WE ALSO LOSE ANOTHER 10 DEGS OFF MX
TEMPS BEHIND THIS FRONT.

PAST THAT...MDLS CONT TO BE ALL OVER THE PLACE W/ STRENGTH/TIMING OF
VARIOUS SYSTEMS...BUT GENERALLY SUGGEST DRY WX THRU FRI...W/ A RETURN

AS STRONG COLD FRONT...PROBABLY THE LAST IN THE SERIES...DIVES THRU
THE PLAINS. WL BASICALLY LEAVE EXTENDED ALONG...XCPT TWEAKING MON A
