WESTERN AND NORTHERN MOUNTAINS. ACCUMULATING SNOW IS LIKELY IN THE
NORTHERN MOUNTAINS...ESPECIALLY OVER THE PEAKS AND ALONG WEST
FACING SLOPES. WINDY CONDITIONS WILL PERSIST INTO EARLY NEXT WEEK
AS TEMPERATURES REMAIN BELOW NORMAL WITH THE POTENTIAL FOR AN
UNSETTLED WEATHER PATTERN TO CONTINUE INTO MID/LATE WEEK.

.DISCUSSION...
SHORTWAVE RIDGING CURRENTLY OVER THE AREA WILL BE REPLACED BY
INCREASING W-SW FLOW OVERNIGHT INTO FRIDAY. W-SW WINDS ALOFT WILL
MIX DOWN TO THE SURFACE FRIDAY AFTERNOON AS TEMPERATURES REACH
ABOVE NORMAL. AT THE SAME TIME...LEE-SIDE TROUGHING WILL DEEPEN
TO NEAR 995MB AT THE SURFACE RESULTING IN BREEZY TO WINDY
CONDITIONS AREA-WIDE AND CRITICAL FIRE WEATHER CONDITIONS (SEE

WINDS ALOFT WILL CONTINUE TO INCREASE FRIDAY NIGHT IN ADVANCE OF A
POTENT SPRING WEATHER-MAKER...FORECAST TO IMPACT OUR AREA THROUGH
THE WEEKEND. STRONG WINDS TO BE THE FEATURED IMPACT SATURDAY...

MODEL SOLUTIONS SHOW THE CORE OF STRONGEST WINDS IN THE MID LEVELS
OF THE ATMOSPHERE ORIENTED FROM SW TO NE ACROSS CENTRAL PORTIONS

SOUTHWEST WIND EVENT SATURDAY FOR MUCH OF THE SOUTH AND EAST...
COMPLETE WITH NORTHEAST TRANSPORT OF SAND OUT OF WHITE SANDS OVER
THE SACRAMENTO MOUNTAINS AND INTO THE EASTERN PLAINS AND TEXAS
PANHANDLE. WILL ISSUE A HIGH WIND WATCH FOR SOME OF OUR SOUTH
CENTRAL AND CENTRAL ZONES WHERE OUR FORECAST CONFIDENCE IS HIGHEST
ON HITTING WARNING THRESHOLDS. THIS WATCH MAY BE EXPANDED LATER
AND OTHER ZONES WILL LIKELY REQUIRE ADVISORIES. PRECIPITATION WILL
BEGIN SATURDAY AFTERNOON OUT WEST AND GRADUALLY TRANSITION EAST
SATURDAY EVENING AHEAD OF THE POTENT UPPER LOW AND ATTENDANT
PACIFIC COLD FRONT. ISOLATED THUNDER IS LIKELY SATURDAY AFTERNOON
AND EVENING WITH THIS SYSTEM AS WELL...BUT LIGHTNING ACTIVITY

BY LATE SATURDAY NIGHT...THE UPPER LOW WILL BE MOVING ENE OUT OVER
THE NE PLAINS WITH PRECIPITATION LOCKED ONTO THE NORTHERN AND WEST
CENTRAL MOUNTAINS. SNOW IMPACTS WITH THIS SYSTEM WILL GENERALLY
BE CONFINED TO AREAS ABOVE 8500 FEET IN THE NORTHERN MOUNTAINS.

CRISTO MOUNTAINS COULD PICK-UP 4 TO 8 INCHES OF SNOW WITH THIS
SYSTEM. A MUCH COLDER AIRMASS WILL MOVE IN BEHIND THE FRONT
SATURDAY NIGHT...WITH TEMPERATURES TRENDING WELL BELOW NORMAL ON
THE MAXES SUNDAY AND MONDAY.

WINDY CONDITIONS LOOK TO PERSIST EARLY NEXT WEEK WITH STRONG
NORTHWEST FLOW BEHIND THE DEPARTING UPPER LOW. SOME PRECIP
POTENTIAL NORTH AND EAST AS WELL WITH ADDITIONAL SHORTWAVE ENERGY
