AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
254 PM MDT THU JUN 29 2006

.DISCUSSION....DISCUSSION...FORECAST CONCERNS ONCE AGAIN CENTER ON
PRECIP TONIGHT THROUGH TUE NIGHT ALONG WITH TEMP TRENDS.

A WELL DEFINED UPPER LEVEL TROF IS INDICATED BY THE LATEST WV
IMAGERY OVR WA. THIS IS THE MAIN ITEM OF INTEREST AS IT WILL BE THE
FIRST IN SEVERAL SYSTEMS THAT WILL HELP IN FLATTENING THE RIDGE.

MAIN FOCUS FOR PRECIP TONIGHT WILL BE TIED TO A SFC LEE TROF OVER
THE HIGH PLAINS WITH A WEAK FRONTAL BOUNDARY DRAPED ACROSS NORTHERN
KS. IN FACT...REGIONAL RADAR MOSAICS INDICATED SOME ISOLATED
CONVECTION BREAKING OUT...MAINLY IN SOUTHEASTERN CO AND CENTRAL KS.
HOWEVER WITH LIMITED INSTABILITY AND WITH LITTLE TO NO FLOW
ALOFT...STORMS SHOULD BE LESS ORGANIZED THAN YESTERDAY AND DISSIPATE
AFTER SS.

RIDGE AXIS WILL SHIFT EASTWARD FRI...RESULTING IN A WAA ADVECTION
PATTERN AS SUGGESTED BY SFC SOUTHERLY FLOW AHEAD OF AN APPROACHING
FRONTAL BOUNDARY. FOLLOWED THE WARMER MET MOS GUIDANCE WITH HIGH
TEMPERATURES REACHING NEAR THE CENTURY MARK. THIS BOUNDARY WL SLIDE
INTO CENTRAL NE FRI NIGHT. BETTER LLVL CONVERGENCE ASSOCIATED WITH A
NOCTURNAL JET WILL SUGGEST FAVORABLE PRECP CHANCES NORTH OF THE
AREA. HOWEVER DECIDED TO CONFINE SLIGHT PRECIP CHANCES ACROSS THE FAR
NORTHERN TIER OF COUNTIES IN CASE ANY OF THE CONVECTION BRUSHES THIS
RGN.

AN ACTIVE WEATHER PATTERN IS SHAPING UP FOR THE WEEKEND AND INTO
NEXT WEEK. MODELS HAVE BEEN PERSISTENT IN THE BREAKDOWN OF THE
WESTERN U.S. RIDGE AS SEVERAL S/WVS TRAVEL ALONG THE TOP OF THE
RIDGE. IN ADDITION... A FRONTAL BOUNDARY WILL SLIDE ACROSS THE
CENTRAL PLAINS SAT...ALTHOUGH THE NAM/WRF IS MORE AGGRESSIVE WITH
THIS THAN THE GFS. WENT TOWARD THE GFS SINCE THE WRF SEEMS A LITTLE
TOO QUICK IN THE TIMING OF THIS BOUNDARY. MEDIUM RANGE MODELS AGREE
IN STALLING THIS BOUNDARY IN OR NEAR THE CWA THROUGH TUE NIGHT. SINCE
THIS PATTERN HAS BEEN CONSISTENT WITH SUCCESSIVE MODEL RUNS...
BROADBRUSHED SLIGHT CHANCE POPS THROUGH THIS PERIOD. HOWEVER BUMPED POPS
INTO THE SCATTERED CATEGORY SUN NIGHT WHERE PROJECTED INSTABILITY
AND MOISTURE ARE SUFFICIENT TO SUSTAIN ANY ORGANIZED TSRA
DEVELOPMENT.

A COOLER PATTERN APPEARS PLAUSIBLE FOR THE START OF THE WEEK
INCLUDING THE 4TH OF JULY WITH HIGH TEMPERATURES REACHING AROUND
SEASONABLE NORMALS. SFC HIGH PRESSURE WILL BUILD INTO THE CENTRAL
PLAINS WED...SUGGESTING THAT THINGS SHOULD DRY OUT WED AND THU.
