AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
240 AM MST TUE NOV 24 2009

.SHORT TERM...THE UPPER LOW CONTINUES TO SPIN EASTWARD AWAY FROM
COLORADO AS RIDGING ALOFT BUILDS FROM THE WEST INTO COLORADO. QUITE
A BIT OF MID LEVEL WARMING WILL TAKE PLACE TODAY AS 700MB TEMPS WARM
CLOSE TO -2C. THIS LOOKS REASONABLE BASED ON UPSTREAM 700MB
READINGS. HOWEVER...MID LVL WARMING RESULTS IN STRONG STABILITY AT
MTN TOP LVL SO LOW LEVELS WILL STRUGGLE TO MIX OUT ABOVE INVERSIONS.
READINGS WILL LIKELY REMAIN IN THE MIDDLE 40S ACROSS LOWER
ELEVATIONS. SATELLITE PICS ALSO SHOWING SOME LINGERING LOW LVL
MOISTURE ACROSS NORTHERN MOUNTAINS AND WILL LEAVE SOME CLOUDS THERE
THIS AM...ESPECIALLY UP ALONG THE DIVIDE.

THE NEXT SYSTEM WILL DIG SHARPLY INTO THE CENTRAL PLAINS STATES
LATER TONIGHT WHICH WILL ONLY BRUSH FAR NERN CO WITH SOME CLOUDS AND
SLIGHT CHANCE OF A FLURRY. THIS SYSTEM IS TOO FAR EAST TO HAVE MUCH
EFFECT ON THE FRONT RANGE AND MTNS SO WILL LEAVE THE DRY FORECAST.

.LONG TERM...SHORTWAVE DROPPING EAST OF US ON WEDNESDAY WILL MAINLY
AFFECT THE EASTERN PLAINS KEEPING TEMPS COOL. LIFT IS SHORT LIVED...
BEST CHANCE FOR ANY SNOW IN THE CORNER AROUND SUNRISE AND I WILL
LEAVE THE 10 PERCENT POPS THERE. MEANWHILE THE MOUNTAINS WILL BE ON
THE EDGE AND SHOULD STILL WARM UP SOME. RIDGE IS OVERHEAD THURSDAY
AND FRIDAY WITH WARMING ALOFT...THOUGH LOW LEVELS ON THE PLAINS WILL
LIKELY LAG BEHIND AS THERE WILL BE LITTLE WIND AND WEAK SUN. I STILL
NUDGED THURSDAYS HIGHS UP A LITTLE IN LINE WITH GUIDANCE.

MODELS STILL SHOWING THE NEXT TROUGH ABOUT SUNDAY WITH MOISTURE
POSSIBLE ARRIVING IN THE MOUNTAINS BY SATURDAY. DETAILS STILL
SKETCHY...SEE NO REASON TO CHANGE THE CURRENT FORECAST.

&&

.AVIATION...VFR CONDITIONS FOR NEXT 24 HOURS WITH MAINLY CLEAR
SKIES. GENERAL DIURNAL WIND PATTERNS TO CONTINUE.

&&

.BOU WATCHES/WARNINGS/ADVISORIES...NONE.
