LOOKS LIKE 16 UTC UPDATE OF DAY ONE OUTLOOK HAD RIGHT IDEA CUTTING
OFF RISK SEVERE ALONG NEB/CO BORDER. SATELLITE/RADAR LOOPS SHOW STORMS
FIRING OVER NORTH-CENTRAL CO...THEN LIFTING NORTH-NORTHEAST. WILL
TAKE A LONG TIME FOR STORMS TO GET AS FAR EAST AS SNY. COMPUTED LI/S

APPARENTLY WHAT MODELS MOVE TO CENTRAL PANHANLE BY 06 UTC/MIDNIGHT
AND INTENSIFY. 18 UTC RUC40 MISSING NORTH-CENTRAL CO QPF BUT 18 UTC
MESO-ETA LOOKS BETTER. BELIEVE IT SPREADS IT TOO FAR TO EAST IN FAR
SOUTH PANHANDLE DURING AFTERNOON HRS. 12 UTC RUN OF NCAR MM5 HAD
1.0 INCH QPF BULLSEYE EAST OF BFF THIS EVENING. WILL SEE IF THIS
VERIFIES. NEXT BIG QPF POSSIBILITY NOT UNTIL SAT EVENING...ACCORDING
TO MODELS. AVN HAS ANOTHER STRONG VORTICITY CENTER OVER CENTRAL

ROCKIES. QUITE WARM TEMPS U.F.N.

.EXTENDED DISCUSSION...
STRONG UPPER RIDGE OF HIGH PRESSURE WILL REMAIN CENTERED OVER THE
SOUTHERN ROCKIES/PLAINS THROUGH PERIOD.  MONSOONAL MOISTURE WILL
CONTINUE TO FLOW FROM OLD MEXICO AND THE DESERT SOUTHWEST INTO THE
INTER-MOUNTAIN REGION AND PACIFIC NORTHWEST.  TEMPERATURES ACROSS THE
FORECAST AREA WILL REMAIN ABOUT THE SAME FROM DAY TO DAY...AS NO
MAJOR FRONTS ARE PROGGED TO PASS THROUGH THE AREA AND THICKNESS
VALUES DON'T CHANGE MUCH.  WITH THE HOT TEMPERATURES AND MONSOONAL
MOISTURE...A CHANCE OF AFTERNOON THUNDERSTORMS CAN BE EXPECTED
EACH DAY ACROSS THE AREA THROUGH THE PERIOD.
