&&

.PREV DISCUSSION... /ISSUED 842 AM MST TUE JAN 2 2007/

DISCUSSION...WARMER AIR IS SURGING NORTHWARD THROUGH MANY OF THE
VALLEYS OF WESTERN MONTANA TUESDAY MORNING. THIS WARMER AIR IS
QUICKLY TURNING PRECIPITATION TO RAIN. HOWEVER...A FEW COLD POOLS
ARE PERSISTING IN NORTHWEST MONTANA AND THE MISSOULA VALLEY AND
OTHER VALLEYS EASTWARD TO SEELEY LAKE. HOWEVER..THE WARMING TREND
WILL CONTINUE AND WE WILL PROBABLY CANCEL MOST WINTER WEATHER
ADVISORIES THIS MORNING. FORECASTS MAY ALSO BE FURTHER MODIFIED TO
INCREASE TEMPERATURES TODAY AND TONIGHT. THE MILD WESTERLY
FLOW...WITH LOTS OF MOISTURE CONTINUES THROUGH TONIGHT. THERE IS LITTLE
CHANCE OF MUCH SIGNIFICANT COOLING INTO WEDNESDAY MORNING.

SNOWFALL TO ELEVATIONS ABOVE 4500 FEET IN THE NORTHERN CLEARWATER
MOUNTAINS EAST INTO NORTHWEST AND WEST-CENTRAL MONTANA TONIGHT.
ISSUED A WINTER STORM WATCH FOR THESE AREAS AS A RESULT. SEE
GTFWSWMSO FOR DETAILS.

RESIDUAL MOISTURE WILL PRODUCE SCATTERED SNOW SHOWERS FOR MOST
AREAS. A SHORT- LIVED RIDGE OF HIGH PRESSURE MOVES OVER THE AREA
ON FRIDAY BUT THE NEXT STRONG PACIFIC STORM SYSTEM MOVES INTO THE
AREA FRIDAY NIGHT AND SATURDAY. LATEST DATA INDICATING THAT THE
AIRMASS WILL REMAIN COLD AND KEEP PRECIPITATION SNOW FOR THE
