CONTINENTAL DIVIDE EARLY THIS MORNING. HOWEVER...OROGRAPHIC LIFT
WORKING WITH RESIDUAL MOISTURE WILL CONTINUE TO BRING SNOW TO THE
NORTHERN AND CENTRAL MOUNTAINS THROUGH AT LEAST MIDMORNING.
THEREFORE...WILL ALLOW CURRENT ADVISORIES TO CONTINUE.
AS ANOTHER PACIFIC STORM MOVES ONSHORE FLOW WILL AGAIN BACK TO
THE SOUTH AND SOUTHWEST YIELDING A WEAK OVERRUNNING REGIME THIS
AFTERNOON AND OVERNIGHT. THIS WILL RESULT IN SOME LIGHT SNOW...
MAINLY OVER THE NORTHERN PORTION OF THE CWFA INITIALLY. SNOW WILL
FILL IN ACROSS THE SOUTH LATER TONIGHT AS THE SYSTEM MOVES ACROSS
THE GREAT BASIN.
THE STORM WILL SWEEP ACROSS THE CWFA ON SATURDAY SPREADING SNOWFALL
OVER THE ENTIRE CWFA. HOWEVER...AS MENTIONED IN THE PREVIOUS
DISCUSSION...THIS STORM WEAKENS SIGNIFICANTLY AS IT MOVES OVERHEAD
WITH MUCH OF THE ENERGY JUST BRUSHING THE FOUR CORNERS AREA. MODEL
QPF OUTPUT NOT IMPRESSIVE AS 7H LEVEL SPECIFIC HUMIDITY REMAINING
AROUND 2 G/KG. ABSENT STRONG MOISTURE SURGE AND IN LIGHT OF LIMITED
FORCING WILL CONTINUE TO WITH SNOW ACCUMULATIONS AT OR A LITTLE

SNOWFALL WILL LINGER ALONG THE DIVIDE SATURDAY NIGHT...DECREASING
OVERNIGHT AS SHORTWAVE RIDGE BUILDS ONCE AGAIN.

SATURDAY IN RESPONSE TO WEAK CAA AND WIDESPREAD SNOW.
.LONG TERM...SUNDAY THROUGH FRIDAY...
THE PROGRESSIVE PATTERN CONTINUES TO BRING A SERIES OF SHORTWAVE
TROUGHS OVER THE FORECAST AREA THROUGH NEXT WEEK AS THE JET STREAM
REMAINS STRETCHED FROM WEST TO EAST ACROSS THE CONUS. INITIALLY A
SHORTWAVE RIDGE WILL BE OVERHEAD ON SUNDAY...AS THE AREA SITS BETWEEN
TROUGHS. MOISTURE WILL CONTINUE TO FLOW OVER THE AREA EVEN WHEN THE
RIDGES ARE IN CONTROL...FOR PERIODS OF CLOUDS AND A FEW SHOWERS
POSSIBLE OVER THE HIGHER TERRAIN...ESPECIALLY NORTH. BY SUNDAY NIGHT
THE FLOW BECOMES SOUTHWEST AS THE NEXT LOW PRESSURE SYSTEM DEVELOPS
OFF THE COAST. THIS DISTURBANCE FOLLOWS THE PREVAILING TREND OF
OPENING UP AND FILLING AS IT QUICKLY MOVES INTO THE GREAT BASIN AND
OVER THE FORECAST AREA MONDAY NIGHT. SHOWERS WILL INCREASE ON MONDAY
FAVORING THE SOUTH...AS MOISTURE INCREASES AND THE UPPER JET NOSES
INTO THE 4-CORNERS AREA. THE BEST CHANCE FOR SNOW WILL BE MONDAY
NIGHT WITH TROUGH PASSAGE AND INTO TUESDAY AS THE UPPER JET REMAINS
STRETCHED OVER THE CENTRAL ROCKIES. THE FAVORED AREA WILL SWITCH FROM
THE SOUTH TO THE NORTH AS THE FLOW BECOMES WEST TO NORTHWEST BEHIND
THE TROUGH AXIS. OROGRAPHIC SHOWERS WILL LINGER OVER THE DIVIDE AREA
INTO TUESDAY NIGHT...MAINLY NORTH. PRECIPITATION WILL SEE A DOWNTURN
BY LATE TUESDAY/TUESDAY NIGHT FROM THE WEST AS RIDGING RETURNS.
MODELS HAVE BEEN FAIRLY CONSISTENT IN KEEPING WEDNESDAY AND THURSDAY

TAKES AIM TO OUR WEST.
TEMPS WILL BE A LITTLE BELOW SEASONAL NORMALS FOR MOST OF THE
PERIOD...WARMING NEXT WEEK TO A LITTLE ABOVE NORMAL.
