RECOMMENDATIONS:  TOP...RCMD MENTION OF ISOLD TSTMS THIS EVE...
OTRW NO CHGS NEEDED.

DISCUSSION:  NGM MODEL OF CHOICE THIS FCST PD AS IT HANDLED PSN OF FNT
THE BEST AND HAS SHOWN MORE CONSISTENCY WITH THE MOVEMENT OF THIS
FEATURE DURG THE PAST SVRL HRS. THE COLD FNT IS MOVING THRU NE ATTM AND
CONTS TO TRIGGER ISOLD SHWRS WHILE SHWRS ARE DVLPG OVR THE COLO FNT
RANGE. ALTHOUGH RFC GRIDDED DATA INDCS NO UPR LVL SUPPORT FOR TRW THIS
AFTN AND EVE THE FACT THAT THERE IS SOME...ALBEIT WK...CNVTV ACTVTY
OCRG ATTM SUGGESTS THAT A TRW OR TWO IS PSBL THIS EVE.  A MENTION OF
TRW OVR NW KS WOULD ALSO BRING AREA IN LN WITH FCSTS FM OMA AND DEN.
ANY ACTVTY THAT DOES OCR SHOULD END QUICKLY WITH LOSS OF DAYTIME
HEATING.

CRNT TEMP FCSTS FOR TNGT LOOK PRETTY GD SO WOULD NOT MAKE ANY BIG CHGS
ATTM.  DEN AND TOP MAY WANT TO LWR TEMPS TO MID 50S FOR TNGT.  RDG TO
MOVE INTO WRN CWA AND WNDS TO GO LGT OVNGT FOR A TM AND THEREFORE KS
GROUP 1 AND COLO ZNS 90-92 SHOULD REACH THE MID 50S WITH GD RADIATIONAL
COOLING XPCD OVR THE RGN.

S WNDS TO THEN SPREAD OVR THE RGN ON FRI RTRNG WRM AND MOIST AIR. VORT
MAX IS PROGD TO MOVE THRU THE AREA BGNG LT AFTN.  NGM Q VECTORS SHO
AREA OF LFT TO BE CENTERED OVR EXTRM NW KS BY 0Z THUS CHC OF TRW IS
WARRANTED FOR THE RGN.
