AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
202 AM MDT WED OCT 1 2014

.UPDATE...
ISSUED AT 747 PM MDT TUE SEP 30 2014

UPDATED THE FORECAST TO INPUT PATCHY FOG MENTION FOR LOCATIONS
EAST OF A LINE FROM MCCOOK NEBRASKA TO GOVE KANSAS. LIGHT
WINDS...MOISTURE POOLING ALONG THE FRONT AND COOLER AIR ADVECTING
IN FROM THE NORTHWEST SHOULD PROVIDE A FAVORABLE ENVIRONMENT FOR
FOG DEVELOPMENT. SOME OF THE HIGH-RESOLUTION MODELS INDICATE DENSE
FOG IS POSSIBLE SO WILL NEED TO WATCH TRENDS CLOSELY TONIGHT.

&&

.SHORT TERM...(TONIGHT THROUGH WEDNESDAY)
ISSUED AT 125 PM MDT TUE SEP 30 2014

LATEST WV IMAGERY AND RAP H5 ANALYSIS SHOW NEGATIVELY TILTED TROUGH
OVER THE NORTHER PLAINS WITH CLOSED CENTER OVER SOUTH DAKOTA. SEVERAL
WEAK EMBEDDED SHORTWAVE TROUGHS ARE CURRENTLY MOVING INTO CENTRAL
COLORADO AND COULD BE IN LINE TO IMPACT OUR CWA OVERNIGHT. AT THE
SURFACE A COLD FRONT CURRENTLY EXTEND FROM JUST EAST OF KMCK SOUTH
ACROSS THE OK/TX PANHANDLES WITH SURFACE HIGH PRESSURE BEGINNING TO
DEVELOP ALON THE CO/KS STATE LINE.

WITH FRONT STILL OVER PAR OF THE CWA I CANT COMPLETELY RULE OUT AN
ISOLATED SHOWER OR THUNDERSTORM OVER FAR EASTERN PART OF OUR CWA
WHERE ML CAPE 500-1500 J/KG IS LINGERING. SUBSIDENCE HAS SUPPRESSED
ANY CONVECTIVE REDEVELOPMENT SO FAR...AND GUIDANCE SHOWS ANY THREAT
REMAINING EAST AS FRONT CONTINUES TO PUSH SOUTH AND EAST OVERNIGHT.
AS WEAK SHORTWAVE TROUGH INDICATED BY NAM TO PASS OVER CWA TONIGHT
COULD BRING A FEW LIGHT SHOWERS/SPRINKLES TO THE NORTHWEST PART OF
THE CWA...HOWEVER THIS SHOULD NOT AMOUNT TO MUCH CONSIDERING
LIMITED MOISTURE/INSTABILITY. OTHER GUIDANCE IS FAVORING DRY
CONDITIONS...SO DECIDED TO JUST KEEP MINIMAL SLIGHT CHANCE POPS IN
PLACE 06-12Z PERIOD. NAM/RAP/SREF HINTING AT STRATUS/FOG
DEVELOPMENT OVER EASTERN CWA WITH MOISTURE POOLING NEAR FRONTAL
ZONE. NOT A LOT OF CONFIDENCE IN THIS AS MID-HIGH CLOUDS WILL BE
INCREASING AND COULD LIMIT FOG/STRATUS POTENTIAL.

LATEST GUIDANCE SHIFTING FRONT FURTHER EAST ON WEDNESDAY...LIMITING
SEVERE POTENTIAL AND BETTER PRECIP POTENTIAL THROUGH MOST OF
WEDNESDAY AFTERNOON PERIOD. CURRENTLY THINK THE BEST CHANCE FOR ANY
AFTERNOON THUNDERSTORM DEVELOPMENT WILL BE TO BE AS FORCING
INCREASES FROM THE WEST/NORTHWEST LATER WEDNESDAY AFTERNOON. I
LIMITED 30-40 POPS TO THE LATE AFTERNOON IN OUR NORTHWEST. I KEPT
SLIGHT CHANCE POPS OVER MOST OF THE CWA WEDNESDAY AFTERNOON MAINLY
DUE TO BUILDING INSTABILITY AND AT LEAST WEAK FORCING BEHIND FRONTAL
ZONE...THOUGH I WOULDN`T BE SURPRISED IF WE REMAIN DRY UNTIL MAIN
PUSH COMES IN LATER WEDNESDAY EVENING.

.LONG TERM...(SATURDAY THROUGH TUESDAY)
ISSUED AT 202 AM MDT WED OCT 1 2014

AN UPPER LEVEL RIDGE WILL BUILD INTO THE FORECAST AREA THIS
WEEKEND AND INTO THE BEGINNING OF NEXT WEEK...WHICH WILL BRING DRY
CONDITIONS AND SLIGHTLY ABOVE NORMAL TEMPERATURES IN THE UPPER 70S
TO LOW 80S. LACK OF FORCING AND JET WINDS WILL BRING PLENTY OF
SUNSHINE WITH LIMITED CLOUD COVER THROUGHOUT THE PERIOD.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING)
ISSUED AT 521 PM MDT TUE SEP 30 2014

VFR CONDITIONS ARE ANTICIPATED FOR MOST OF THIS FORECAST CYCLE.
ONLY CAUSE FOR CONCERN IS SOME OF THE HIGH-RESOLUTION MODELS ARE
INDICATING POTENTIAL FOG AROUND KMCK. MOST GUIDANCE HINTS THAT
FOG REMAINS SOUTHEAST OF TERMINAL BUT IT IS A LITTLE CLOSE FOR
COMFORT. PLACED A 6SM BR/SCT015 GROUP AS A HEDGE FOR NOW AND WILL
REFINE THIS GROUP AT THE 06Z RUN. OTHER THAN THAT...EXPECT LIGHT
AND VARIABLE WINDS WITH PERIODS OF MID/UPPER LEVEL CLOUDINESS.
