Area forecast discussion, Aug 10, 5:39 PM MDT, 3 hours 21 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
539 PM MDT WED AUG 10 2011

.DISCUSSION...
232 PM MDT WED AUG 10 2011

EARLY AFTERNOON WV IMAGERY AND H5 ANALYSIS SHOW BROAD/FLAT RIDGE
CONTINUING TO PERSIST OVER SOUTHERN CONUS...WITH WESTERLY FLOW
ACROSS CENTRAL/HIGH PLAINS. CWA CURRENTLY ON SUBSIDENT SIDE OF PV
ANOMALY...WHICH IS CURRENTLY CENTERED OVER CENTRAL NEBRASKA. FRONT
THAT PUSHED THROUGH CWA LAST NIGHT CURRENTLY STALLED OVER SW KS
WITH EASTERLY SURFACE FLOW NORTH OF FRONT KEEPING TD IN THE
UPPER 50S/LOW 60S ACROSS CWA.

IMMEDIATE CONCERNS ARE ON POTENTIAL THUNDERSTORM ACTIVITY THIS
AFTERNOON/EVENING. CLOUD COVER HAS BEEN SLOW TO BURN OFF OVER
EASTERN CWA...WHICH HAS LED TO DIMINISHED TSRA POTENTIAL IN THESE
AREAS...DESPITE PRESENCE OF BETTER SYNOPTIC SCALE LIFT. BETTER LAPSE
RATES...AND THUS HIGHER MIXED LAYER CAPE VALUES ARE CURRENTLY
LIMITED TO HIGHER TERRAIN OVER EASTERN COLORADO...WITH STRONG CAP
IN PLACE OVER CWA. CLEARING SKIES OVER WESTERN CWA SHOULD
CONTINUE ALLOW FOR INCREASING INSTABILITY...WITH RELATIVELY STRONG
CIN LIKELY LIMITING COVERAGE. COULDNT RULE OUT AN ISOLATED TSRA
MOVING OFF THE HIGHER TERRAIN SO HAVE LEFT SLIGHT CHANCE POPS OVER
EASTERN COLORADO COUNTIES. FRONT ATTEMPTS TO LIFT NORTH
OVERNIGHT...WHERE WEAK THETA-E CONVERGENCE MAY SUPPORT ISO TSRA
OVER SOUTHERN TIER OF COUNTIES IN CWA. DUE TO THE LIGHT NATURE OF
EAST WINDS...AND PROXIMITY OF THE FRONT COULD SEE SOME PATCHY FOG
DEVELOPMENT. WAS NOT CONFIDENT ENOUGH TO INCREASE FOG COVERAGE
BEYOND PATCHY.

WESTERLY FLOW CONTINUES THROUGH END OF WEEK WITH WEAK WAVES PASSING
THROUGH MEAN FLOW COMBINING WITH LINGERING FRONTAL BOUNDARY WITHIN
VICINITY OF CWA TO KEEP TSRA CHANCES OVER PARTS OF CWA THU AND FRI.
BEST SYNOPTIC SCALE ENERGY APPEARS TO PASS THROUGH CWA FRI...WITH
MAIN FOCUS OVER EASTERN LOCATIONS WHERE I KEPT POPS IN CHANCE
CATEGORY. H5 RIDGE STRAIGHTENS OVER CENTRAL ROCKIES SAT. DUE TO
LOCATION OF RIDGE...CWA REMAINS IN NW FLOW...WHICH WILL CONTINUE
TO ALLOW WAVES TO PASS WITHING VICINITY OF CWA INTO EARLY NEXT
WEEK. COMBINED WITH PERSISTENT EASTERLY FLOW IN THE BOUNDARY LAYER
CANT COMPLETELY RULE OUT TSRA CHANCES ANY DAY IN PARTICULAR.
TIMING OF UPPER LEVEL DISTURBANCES AND BEST INSTABILITY IN
PROXIMITY TO SURFACE FEATURES IS STILL HARD TO PIN DOWN...SO I
ONLY MADE MINOR ADJUSTMENTS TO PREVIOUS FORECAST KEEPING SLIGHT
CHANCE/CHANCE POPS ACROSS MOST OF CWA THROUGH EXTENDED PERIODS.

.AVIATION...
538 PM MDT WED AUG 10 2011

FOR THE 00Z TAFS...ONGOING CONVECTION TO THE NORTHWEST OF THE AREA IS
EXPECTED TO WEAKEN AS IT PROGRESSES TO THE EAST/SOUTHEAST. NONETHELESS
CANNOT COMPLETELY RULE OUT THE POTENTIAL FOR THESE STORMS TO MAKE IT
TO THE SITES SO WILL AT LEAST CARRY CB GROUPS FOR NOW AND AMMEND AS
NEEDED. IFR CONDITIONS ARE EXPECTED TO DEVELOP AT BOTH TERMINALS AS
ABUNDANT LOW-LEVEL MOISTURE CONTINUES IN PLACE ON LIGHT S/SE WINDS OVERNIGHT.
VFR CONDITIONS ARE EXPECTED TO RESUME BY MID- MORNING WITH ANOTHER SLIGHT
CHANCE OF THUNDERSTORM ACTIVITY TOWARDS THE END OF THE VALID PERIOD.
THOUGH COVERAGE IS NOT EXPECTED TO BE HIGH...STORMS THAT DO FORM WILL
HAVE THE POTENTIAL TO BECOME SEVERE WITH LARGE HAIL AND STRONG WINDS.
