314 PM MST THU FEB 17 2011

.SHORT TERM...

(TONIGHT AND FRIDAY)

...MAIN PROBLEM EARLY TONIGHT IS WHETHER A WEAK FRONT MOVES INTO THE
AREA FROM THE NORTH BEFORE MIDNIGHT...

UPPER JET AXIS HAS SHIFTED SOUTH AND EAST...AND IS MOVING OUT OF THE
AREA EARLY THIS EVENING. USED THE NAM FOR MOST OF THE PERIOD...AS IT
SEEMS TO HAVE THE BEST DETAIL AND CONTINUITY.

THE STRONG WEST TO SOUTHWEST WINDS WILL GRADUALLY DIMINISH THROUGH
THIS EVENING. THEN...AS COOLER AIR MOVES INTO THE AREA BEHIND A
FRONTAL BOUNDARY...WINDS SHOULD DROP OFF RAPIDLY...EXCEPT OVER THE
HIGHER MOUNTAINS AND ALONG THE EASTERN MOUNTAIN SLOPES. WINDS IN
THESE AREAS WILL DIMINISH BEFORE MIDNIGHT. ANY PRECIPITATION WHICH
CONTINUES OVER THE CONTINENTAL DIVIDE SHOULD GENERALLY BECOME
ISOLATED TO SCATTERED AFTER ABOUT 9 PM. LOWS WILL GENERALLY BE IN
THE SINGLE DIGITS AND TEENS IN THE HIGH COUNTRY AND 20S ON THE
PLAINS.

WINDS FRIDAY WILL BE GENERALLY LIGHT...AS WE ARE BETWEEN SYSTEMS.
BY LATE AFTERNOON...THE NEXT SYSTEM WILL APPROACH THE SOUTHWEST AND
CENTRAL MOUNTAINS...INCREASING CHANCES OF SNOW AND WINDS. HIGHS ON
THE PLAINS WILL BE ABOUT 10 DEGREES COOLER FRIDAY.

TIMES...TO THE EASTERN SAN JUAN AND LA GARITA MTS SATURDAY WITH THE
HEAVIEST SNOW SHIFTING FURTHER NORTH TO THE EASTERN SAWATCH AND
MOSQUITO RANGES LATER SATURDAY AND SUNDAY AS FLOW BECOMES MORE
WESTERLY AS UPPER TROUGH CONTINUES TO LIFT OUT ACROSS THE ROCKIES.

ALLOWING FOR A NICE WARM UP WITH HIGHS IN MID 50S TO MID 60S ON
SATURDAY. LATEST MODELS INDICATING INCREASING LOW LEVEL MOISTURE
