UT UPPER LOW APPEARS TO STILL BE DIGGING PER SATL IMAGERY.  THE 00Z
NAM APPEARS TO HAVE THE BEST SOLUTION AMONG SHORT TERM MODELS WITH A
MORE SWD TRACK/DEVELOPMENT OF THE H7 LOW.  BY 12Z...THE ATTENDANT
LOW SHOULD BE ACROSS SERN CO...WITH AN INCREASING DEEP NNELY UPSLOPE
COMPONENT DEVELOPING ACROSS THE FRONT RANGE AND PALMER DIVIDE.

20-30 KTS IN THE LOWEST 1-2 KM.

SPREAD ACROSS THE FRONT RANGE INTO ERN CO BETWEEN 06-12Z.  AS THE
COLUMN SATURATES BETWEEN NOW AND 09Z...WET-BULB COOLING AND
INCREASING ICE PRODUCTION AT CLOUD TOP WILL CONTRIBUTE TO A
CHANGEOVER TO ALL SNOW.  MAGNITUDE OF MOIST UPSLOPE FLOW AND STRONG
DIFFLUENT FLOW ALOFT WILL BE FAVORABLE FOR HEAVY SNOWFALL WITH RATES
OF 1-2 INCHES PER HOUR...PRIMARILY AFTER 09Z ALONG THE FRONT
