AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
300 PM CDT SUN JUL 15 2001

12Z 5H LVL SHOWING 40-60M HT FALLS OVER MOST OF THE WESTERN CONUS
WITH A WEAK UPPER HIGH OVER TX AND MAINLY A WESTERLY FLOW ALOFT OVER
KS. W/V AND 5H ANALYSIS ALSO STILL SHOWING SEVERAL EMBEDDED WAVES
UPSTREAM, ONE OF WHICH (VIA W/V LOOP) CROSSING THE COLORADO ROCKIES
AT THIS TIME. THIS ONCE AGAIN IS AIDING IN STORMS TO DEVELOP OVER
THE HIGHER ELEVATION AS OF 2 PM. 85H LVL THIS MORNING SHOWING
MOISTURE POOLING ALONG A BAROCLINIC ZONE IN THE PANHANDLE OF TX WITH
SOME WAA OVER THE FAR SW CWA. SBCAPES HERE APPEAR TO BE CLIMBING
INTO THE 2000-300J/KG IN THIS AREA AND WITH AFTERNOON CU DEVELOPING
IN THIS REGION COULD SEE A FEW TSRA EARLY THIS EVENING NEAR EHA AND
LBL. FURTHER WEST W/V LOOP SHOWING S/W TROF LIKELY TO MOVE NORTHWEST
OF OUR AREA EARLY TONIGHT, BUT GIVEN THE FLOW AND A WEAK BAROCLINIC
ZONE NEAR OUR NORTHERN CWA A FEW TSRA COULD CROSS THIS AREA AS WELL
BEFORE DISSIPATING. ELSEWHERE A FEW AND FAR BETWEEN SHOWERS WILL
ALSO BE POSSIBLE BUT HAVE OPTED TO KEEP FORECAST DRY FOR NOW OR
DEPENDING ON CU DEVELOPMENT AT ISSUANCE TIME MAY GO WITH SOME LESS
THAN 20 POPS.

FOR EARLY NEXT WEEK WILL CONTINUE TO SEE AN UPPER RIDGE BUILD INTO
THE CENTRAL PLAINS ON MONDAY AND TUESDAY AS UPPER LEVEL TROF DEEPENS
AND ENTERS THE WESTERN CONUS. SOUTHWEST FLOW DEVELOPING OVER CO/NM
WHICH WILL CONTINUE TO SUPPLY SEVERAL EMBEDDED WAVES ACROSS THE
PLAINS THROUGH TUESDAY. 85H THERMAL RIDGE AND LEE SFC TROF WILL BE
POSITIONED OVER PARTS OF CWA BOTH DAYS. THIS MAY PROVIDE FOR SOME
FOCUSING AT THE SURFACE FOR LATE DAY STORM WITH EACH SUCCESSIVE
WAVE, HOWEVER ATMOSPHERE OVER MUCH OF WESTERN KANSAS WILL BE WARM
AND DRY. THEREFORE CURRENT FORECAST LOOKS RIGHT ON TRACK WITH DRY
CONDITIONS AND TEMPERATURES CLIMBING BACK WELL INTO THE 90S WITH
EVEN A FEW 100S POSSIBLE BY TUESDAY.

EXTENDED DISCUSSION...

OVER TIME, MODELS TRENDING TOWARD SHIFTING UPPER RIDGE BACK WEST AND
REBUILD STRONG CAP.  MAY BE CHANGING BACK TO SEVERAL ROUNDS OF TSRA
FOR NORTHERN PLAINS AS WAS THE CASE IN RECENT WEEKS WITH CWA DRY.
DECIDED TO GO AHEAD AND REMOVE TSRA CHANCES FOR LATER PART OF
FORECAST BASED ON THIS. WILL ALSO MAINTAIN TEMPS ABOVE CLIMO THROUGH
DAY 10.
