.DISCUSSION...
307 AM MST TUE DEC 15 2009

ARCTIC AIR WILL GET NUDGED A LITTLE FURTHER EAST TODAY...PROBABLY 
STOPPING SOMEWHERE IN THE FIRST COLUMN OF COUNTIES IN NORTHWEST 
KANSAS BASED ON 925MB WIND AND TEMPERATURE PROGS...EXCEPT IN THE 
REPUBLICAN RIVER VALLEYS. A VERY SHARP TEMPERATURE GRADIENT WILL 
EXIST ACROSS THE BOUNDARY...40S AND 50S ON THE WARM SIDE BUT TEENS 
AND 20S ON THE COLD SIDE...WITH ONLY A FEW MILES SEPARATING THEM. 
GOODLAND WILL BE VERY CLOSE TO THE BOUNDARY. THE STRATUS AND FOG 
POTENTIAL WILL BE PATCHY IN NATURE AND WILL MONITOR OBS/SATELLITE UP 
TO ZONE ISSUANCE TIME. LOW AMPLITUDE SHORTWAVE RIDGING ACROSS THE 
PLAINS ON WEDNESDAY WILL JUST ABOUT SCOUR OUT THE ARCTIC AIR...BUT 
IT WILL TRY TO HANG TOUGH ACROSS THE EASTERN 6 COUNTIES. SHORTWAVE 
TROUGH WILL APPROACH FROM THE NORTHWEST LATE THURSDAY...ACCOMPANIED 
BY COLDER BUT NOT BITTERLY COLD AIR. STILL SOME DIFFERENCES BETWEEN 
THE ECMWF AND GFS ON PRECIPITATION CHANCES. THE EC DIGS THE TROUGH A 
BIT FURTHER SOUTH AND WEST AND GENERATES WIDESPREAD BUT LIGHT 
QPF...WHILE THE GFS KEEPS MOST PRECIPITATION TO THE NORTH AND EAST. 
WILL KEEP THE 20 POPS GOING IN THE FORECAST FOR NOW.

.AVIATION...
426 AM MST TUE DEC 15 2009

FOR THE 12Z TAFS...VFR CONDITIONS SHOULD CONTINUE FOR THIS TAF 
PERIOD AT BOTH KGLD AND KMCK. MAIN QUESTION IS WHETHER CURRENT 
PATCHY STRATUS DECK OVER EASTERN COLORADO WILL SHIFT EAST INTO KGLD. 
SATELLITE INDICATES THE AREA DRIFTING NORTH SO DO NOT EXPECT IT TO 
AFFECT KGLD. TIME-HEIGHT CROSS SECTIONS SHOW SCT HIGH CLOUDS WILL BE 
THE MAIN CLOUDS AFFECTING THE AREA.
