.DISCUSSION...
206 PM MST TUE DEC 1 2009

THE 20Z SURFACE ANALYSIS AND METARS SHOWING THE COLD AIR MOVING
SOUTH INTO NORTHWEST KANSAS. LIGHT SNOW WAS REPORTED OVER NORTHERN
WYOMING. THE UPPER TROUGH CAN BE SEEN VIA WATER VAPOR IMAGERY OVER
THE NORTHWEST CONUS.

UPPER FLOW WILL BE ZONAL TONIGHT AHEAD OF THE INCOMING NORTHERN 
STREAM TROUGH. THE UPPER TROUGH WILL PERSIST OVER THE 
CENTRAL/NORTHERN PLAINS THROUGH THURSDAY NIGHT WITH NORTHWEST FLOW 
FOLLOWING AS A RIDGE BUILDS INTO THE ROCKIES. A COLD FRONT WILL MOVE 
INTO NORTHWEST KANSAS EARLY THIS EVENING FOLLOWED BY HIGH PRESSURE 
THROUGH THE REMAINDER OF THE WEEK.

PRECIPITATION CHANCES APPEAR TO BE MAINLY TONIGHT AND WEDNESDAY OVER 
EASTERN COLORADO. FORECAST SOUNDINGS SHOW MOISTURE PROFILE TO BE 
MARGINAL. FORCING IS ALSO MARGINAL WITH ISENTROPIC DOWNGLIDE 
INDICATED THROUGH THE ENTIRE TIME PERIOD. FOR THAT REASON WILL NOT 
INCREASE POPS BUT KEEP CURRENT SCATTERED FLURRIES OVER THE COLORADO 
ZONES CLOSER TO SOME FORCING WEST OF THE AREA. REMAINING PERIODS 
WILL HAVE NIL POPS DUE TO SUBSIDENCE AND LACK OF MOISTURE.

850MB TEMPERATURES FALL BELOW ZERO AND STAY THERE THROUGH FRIDAY. 
TEMPERATURES WILL SLOWLY RISE FROM LOWS IN THE TEENS TO THE LOWER 
30S WITH WESTERN AREAS ONLY REACHING THE MID 20S.

IN THE EXTENDED...UPPER FLOW THROUGH THIS PART OF THE FORECAST IS 
ZONAL WITH SOME TRANSITION TO WEST SOUTHWEST FLOW LATE AS LOW MOVES 
INTO THE DESERT SOUTHWEST. SURFACE HIGH PRESSURE WILL BE OVER THE 
REGION. POPS WILL REMAIN NIL THROUGH THE FORECAST DUE TO THE LACK OF 
ANY SIGNIFICANT DYNAMICS. TEMPERATURES WILL BE THE MAIN FOCUS WITH 
850 TEMPERATURES BELOW ZERO. HIGH TEMPERATURES WILL STRUGGLE TO GET 
INTO THE LOWER 30S AND MINS WILL FALL INTO THE TEENS.
