.PREV DISCUSSION... (ISSUED 257 AM MST FRI DEC 2 2005)

SHORT TERM...UPPER TROF AND ASSOCIATED ENHANCED MOISTURE FIELD
SPREADING OVER THE CWA NOW BUT NOT A LOT OF PCPN AS OF YET.  STILL
EXPECT DECENT SHOT OF SNOW OVER THE SOUTHERN MTNS TODAY THUS WILL
CONTINUE THE SNOW/BLOWING SNOW ADVY.  MOST PCPN EXPECTED OVER THE
WRN CWA AIDED BY OROGRAPHICS WHILE OVER THE EASTERN PLAINS SNOW WILL
BE HINDERED BY DOWNSLOPING FLOW.  TEMPS WARMER TODAY AS THICKNESSES
RISE BUT WARMING SHORT-LIVED AS PASSAGE OF UPPER SHORTWAVE WILL PUSH
COLDER AIR BACK SOUTH ACROSS THE CWA TONIGHT.  SNOW WILL ALSO TAPER
OFF OVERNIGHT AS HIGHER MOISTURE SHIFTS SOUTH ACROSS COLORADO BUT
SOME SNOW SHOWERS EXPECTED THRU SUNDAY AS FAVORABLE OROGRAPHIC FLOW
PERSISTS OVER THE SRN MTNS.

LONG TERM...SATURDAY NIGHT THROUGH THU. NORTHWESTERLY FLOW ALOFT
SUNDAY WILL STAY NORTHWESTERLY AND STRENGTHEN MON AS SHORTWAVE
ENERGY MOVES ACROSS THE AREA. SHORTWAVE ENERGY WILL CONTINUE TO
CARVE OUT A DEEP AND STRONGLY TILTED UPPER TROUGH TUE AND THE
TROFFINESS WILL PERSIST INTO WED. NEW GUIDANCE HAS WED EVEN COLDER
THAN TUE...BUT AT THIS POINT I AM SKEPTICAL REGARDING THE STRENGTH
OF THE TROUGH WED DUE TO THE AMPLITUDE AND PROXIMITY OF THE TILTED
RIDGE TO OUR NORTHWEST. IN ANY EVENT...UPPER FLOW WILL BACK TO
NORTHWESTERLY THU AS THE TROUGH MIGRATES EASTWARD AWAY FROM WY.
CLOSER TO THE GROUND...AN INVERTED TROUGH OVER THE AREA SAT NIGHT
AND SUN WARRANTS A CHANCE OF SNOW WITH THE HIGHEST POPS IN THE
MOUNTAINS DUE TO OROGRAPHY. COLD AIR ADVECTION WILL MAKE SUN COLDER
THAN SAT. MON WILL REMAIN ON THE COLD SIDE WITH A CHANCE OF SNOW. AN
ARCTIC FRONT WILL SWEEP THROUGH THE AREA LATE MON. TUE WILL BE QUITE
COLD WITH UPSLOPE FLOW PRODUCING A BETTER CHANCE OF SNOW. LOW LEVEL
LEESIDE TROUGHING WED WILL MODERATE TEMPERATURES...ALTHOUGH WED WILL
STILL BE COLD. DOWNSLOPE FLOW WILL DRY THINGS OUT WED EXCEPT IN THE
HIGHEST MOUNTAINS WHERE SOME LIGHT OROGRAPHIC SNOW IS POSSIBLE.
CONTINUED DOWNSLOPE FLOW WILL PRODUCE A MILDER AND DRY DAY THU.
