AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
239 PM MDT TUE SEP 23 2014

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 238 PM MDT TUE SEP 23 2014

LATEST SATELLITE AND UPPER AIR ANALYSIS INDICATE A CLOSED UPPER
LEVEL LOW OVER THE NORTHERN PLAINS.  EXTENDING SOUTH FROM THE UPPER
LEVEL LOW IS AN UPPER LEVEL TROUGH AXIS.  AT THE SURFACE A TROUGH
WAS MOVING EASTWARD.  ALONG THE TROUGH AND UNDER UPPER LEVEL TROUGH
AXIS SOME SHOWERS WERE BEGINNING TO DEVELOP OVER KIT CARSON AND
CHEYENNE COUNTIES.

THROUGH THE REST OF THE AFTERNOON EXPECT THE SURFACE TROUGH TO
CONTINUE MOVING EASTWARD AHEAD OF THE UPPER LEVEL TROUGH AXIS...WITH
STORMS DEVELOPING ALONG THE SURFACE FEATURE.  MORE ISOLATED STORMS
WILL DEVELOP BEHIND THE SURFACE TROUGH AHEAD OF AN UPPER LEVEL
TROUGH AXIS. STORM COVERAGE WILL INCREASE TOWARD LATE AFTERNOON AS
THE STORMS MOVE EAST INTO HIGHER INSTABILITY.

THIS EVENING STORM COVERAGE WILL REACH A PEAK THEN GRADUALLY
DIMINISH AS SURFACE HEATING DISSIPATES.  OVERNIGHT KEPT IN SOME VERY
LOW CHANCES TO ACCOUNT FOR SOME LINGERING LIFT PRIOR TO THE UPPER
LEVEL TROUGH AXIS MOVING EAST OF THE AREA.  MEANWHILE THE SURFACE
TROUGH MOVES ROUGHLY HALFWAY THROUGH THE AREA BEFORE WASHING OUT.

WEDNESDAY DRY AND SLIGHTLY WARMER CONDITIONS WITH LIGHT WINDS CAN BE
EXPECTED BEHIND THE UPPER LEVEL TROUGH AXIS.  THE SURFACE TROUGH
MOVES THROUGH THE AREA WITH WINDS TURNING TO THE NORTHWEST THEN THE
EAST BEHIND IT.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 114 PM MDT TUE SEP 23 2014

A SYSTEM DIGGING INTO THE GREAT BASIN WILL CAUSE UPSTREAM RIDGE
AMPLIFICATION WHICH WILL BE THE DOMINANT FEATURE AT LEAST THROUGH
THE WEEKEND. DRY CONDITIONS AND ABOVE NORMAL TEMPERATURES ARE
EXPECTED. THE WESTERN TROUGH WILL BECOME CLOSED LOW AND MAKE ONLY
VERY SLOW PROGRESS TOWARDS THE ROCKIES. THE FIRST HINT OF
PRECIPITATION CHANCES ASSOCIATED WITH THAT SYSTEM DOES NOT ARRIVE
UNTIL MONDAY AT THE EARLIEST. BY THAT TIME IT IS WEAKENING AND
TRACKING ACROSS THE NORTHERN ROCKIES. WILL CARRY SOME LOW POPS
DURING THAT TIME PERIOD BUT PATTERN DOES NOT LOOK VERY GOOD FOR
PRECIPITATION CHANCES. TEMPERATURES WILL BEGIN A SLOW COOLING
TREND OVER THE WEEKEND...REACHING NEAR NORMAL BY EARLY NEXT WEEK.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON)
ISSUED AT 1151 AM MDT TUE SEP 23 2014

VFR CONDITIONS FORECAST FOR THE 18Z TAFS. MAIN ISSUE WILL BE THE
TIMING OF THUNDERSTORMS LATE THIS AFTERNOON AND EARLY EVENING.
ANTICIPATE STORMS TO INITIALLY FORM ALONG A SURFACE TROUGH THAT IS
CURRENTLY MOVING IN FROM THE WEST. THE STORMS WILL THEN MOVE
EASTWARD. AM THINKING THE COVERAGE WILL BE SPARSE ENOUGH TO NOT
NECESSITATE A MENTION IN THE KGLD TAF BUT WILL BE ENOUGH TO
MENTION IN THE KMCK TAF. BEHIND THE TROUGH WINDS WILL TURN TO THE
WEST TONIGHT THEN THE NORTHWEST WEDNESDAY.

.GLD WATCHES/WARNINGS/ADVISORIES...
