EVENT...UPPER LEVEL FORCING FOR SNOW IN N SIERRAS...SHORT WAVE OUT AHEAD
WITH EXPANDING BAROCLINIC LEAF N AZ INTO S UT THAT WILL REINFORCE SNOW
SW COLORADO INTO N NM...
.
SATELLITE ANALYSIS AND TRENDS...BIG PICTURE WATER VAPOR FEATURES FOR
WEST AREA WAS UPPER LEVEL LOW DROPPING SOUTH THROUGH INTERIOR WESTERN
OREGON..GENERATING SHORT WAVE IMPULSES OUT AHEAD S CENTRAL OREGON INTO THE
N SIERRAS.  ENOUGH LIFT FROM THE SHORT WAVES AND MOUNTAIN LIFT TO GO ALONG
WITH WEAK MOISTURE WERE HELPING PRODUCE LIGHT TO MODERATE/OCCASIONAL HVY
SNOW HIGHER ELEVATIONS OF NORTHERN SIERRAS.  JET BEING FORCED SOUTH TO
CENTRAL CA COAST AND INLAND FROM THERE ACROSS C AZ INTO NM.  ADDITIONAL
SHORT WAVE ENERGY SOUTHERN NEVADA INTO SOUTHERN UT ALONG WITH CONTINUED
WEAK MOISTURE ADVECTION AND OVERRUNNING 700-500MB BOUNDARY ORIENTED WNW
TO ESE ACROSS S NV THRU C AZ ALSO HELPING WITH OVERRUNNING SNOWS ACROSS
FAR NORTHERN AZ AND SW TO S CENTRAL UT AND PROGRESSING EAST AND NE AND
EXPECT EXPANSION OF THIS SNOW TO BEGIN THE INCRD SNOW PROCESS FOR SW
COLORADO LATER THIS MORNING.   JET AND HIGH LEVEL SHORT WAVE ENERGY
NOW PUSHING ACROSS INTERIOR SE CA AND WESTERN AZ..SO EXPECTING FURTHER
DEVELOPMENT OF BAROCLINIC LEAF CLOUD SIGNATURE N AZ INTO SOUTHERN UT
FOR INCREASED SNOW AS THE MORNING WEARS ON AND THAT EXPANDING INTO SW
COLORADO NOT FAR BEHIND ESPECIALLY HIGHER SPOTS LATER THIS MORNING.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 1100-1400Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...STEADY SNOW WITH INCREASED MODERATE TO HVY SNOW
BURSTS HIGH SPOTS OF N SIERRAS THIS PERIOD AS UPPER LEVEL LOW/TROUGH AND
SHORT WAVES OUT AHEAD PROVIDED NEEDED LIFT FOR SNOW PRODUCTION HIGHER
ELEVATIONS.    EXPECT BAROCLINIC LEAF TO DEVELOP FURTHER ACROSS N AZ INTO
SW AND S CENTRAL UTAH AND EXPAND FURTHER INTO SW COLORADO BY END OF THIS
PERIOD OR LATER THIS MORNING TO INCRD SNOWS IN SW TO S CENTRAL COLORADO,
ESPECIALLY HIGH SPOTS AND WITH GOOD SW OROGRAPHIC LIFT AS WELL AS THE
DAY WEARS ON THERE.  FOR SOUTHERN UT/NORTHERN AZ INTO THE SW QUARTER OF
COLORADO...A LONG DRAWN OUT SNOW EVENT AS PARADE OF SHORT WAVES APPROACH
AREA FROM THE WEST OF NORTHWEST FOR MULTIDAY EVENT.
