120 PM MDT WED AUG 6 2003

TONIGHT...VISIBLE SATELLITE IMAGERY/LOOK OUT THE WINDOW SUGGEST
MINIMAL THUNDERSTORM CHANCES. MID LEVEL TEMPERATURES OF 14-16C WILL
LIKELY INHIBIT ALL BUT ISOLATED THUNDERSTORM DEVELOPMENT. GUIDANCE
TEMPERATURES LOOK REASONABLE.

THURSDAY...UPPER RIDGE AXIS PARKS ITSELF ACROSS THE WESTERN HIGH
PLAINS AND THE CONEKA REGION (COLORADO/NEBRASKA/KANSAS) WITH 500 MB
HEIGHTS NEAR 597 DEKAMETERS. WITH WARM MID LEVEL TEMPERATURES NEAR
16C AND MINIMAL FORCING...THUNDERSTORM CHANCES APPEAR SLIM. GUIDANCE
HIGHS LOOK TOO COOL WITH 850 MB TEMPERATURES NEAR 30C.

THURSDAY NIGHT...THUNDERSTORMS THAT INITIATE ALONG THE NORTHERN
PERIPHERY OF THE UPPER RIDGE MAY MIGRATE ACROSS THE NEB/KS ZONES
LATE AS PER ETA DEPICTION...SO WILL GO WITH 20-30 PERCENT CHANCES.

FRIDAY...RIDGE ALOFT DOMINATES AGAIN. HOWEVER...MID LEVEL
TEMPERATURES COOL SOMEWHAT. WITH LOW/MID LEVEL MOISTURE AXIS IN THE
AREA...COULD SEE SCATTERED LATE AFTERNOON/EVENING THUNDERSTORMS...

HIGHS AGAIN LOOK TOO COLD PER 850 MB TEMPERATURES.

SATURDAY...RIDGE ALOFT CONTINUES TO DOMINATE. GFS SUGGESTS A LOW

GUIDANCE HIGHS LOOK TOO COOL PER 850 MB TEMPERATURES.

SUNDAY...MASSIVE UPPER RIDGE DOMINATES THE ROCKIES WHILE AN
IMPRESSIVE SHORTWAVE TROUGH LIES FURTHER EAST USHERING IN COLDER AIR
INTO OUR REGION VIA A BACKDOOR TYPE FRONT. WILL THUS COOL
TEMPERATURES BACK NEAR NORMAL. WILL CONTINUE WITH A DRY FORECAST
SINCE MID LEVEL TEMPERATURES WILL REMAIN QUITE WARM AND LIKELY
INHIBIT THUNDERSTORMS.

HIGH TEMPERATURES SHOULD BE ABOVE GFS GUIDANCE PER GFS COOL BIAS AND
500 MB HEIGHT FIELDS. CANNOT RULE OUT AFTERNOON/EVENING
