AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
900 AM MDT SAT APR 9 2011

.SYNOPSIS...A COLD PACIFIC STORM WILL CONTINUE TO IMPACT THE
REGION THROUGH EARLY SUNDAY. HIGH PRESSURE WILL BRIEFLY RETURN
SUNDAY NIGHT INTO MONDAY...BEFORE ANOTHER SERIES OF PACIFIC
SYSTEMS AFFECTS THE AREA THROUGH MIDWEEK.

&&

.DISCUSSION...WATER VAPOR LOOP SHOWS THE UPPER TROUGH SLOWLY MOVING
EAST ACROSS NEVADA AS COLDEST AIR ALOFT BEGINS TO ENTER NORTHERN
ARIZONA. SEVERAL WAVES EJECTING OUT OF THIS FEATURE NORTHWARD ACROSS
UTAH SERVING TO ENHANCE PRECIPITATION UNDER COOLING CLOUD TOPS PER
IR IMAGERY. HAVE INCREASED POPS PER THESE OBSERVATIONS ACROSS MUCH
OF THE REGION...EXCEPT LOWERING THEM IN DIXIE AS DEEP LAYER MOISTURE
MARCHES EAST.

PRECIPITATION TYPE WILL REMAIN SNOW ACROSS WESTERN TWO THIRDS OF THE
STATE EXCEPT LOWEST ELEVATIONS OF DIXIE AS COOLING CONTINUES
THROUGHOUT THE DAY...WITH MIXED PRECIPITATION EXPECTED CLOSER TO THE
GREEN RIVER. RELATIVELY WARM SURFACES PLUS HIGH SUN ANGLE OF EARLY
APRIL SHOULD SERVE TO OFFSET IMPACT OF ACCUMULATIONS MOST VALLEYS
EXCEPT DURING HIGHEST SNOW RATES. LOWERED TEMPERATURES GIVEN HIGHS
SEEN YESTERDAY AND CONTINUED PRECIPITATION/COOLING TO TAKE PLACE
TODAY.

THE OTHER CHANGE WAS TO MENTION CONVECTIVE PRECIPITATION WORDING
ACROSS THE WESTERN PORTION OF THE STATE THIS AFTERNOON AS COLD AIR
ALOFT ARRIVES...AND CLOSER TO THE GREEN RIVER AS BAROCLINIC ZONE
MARCHES EASTWARD. WHILE 03Z SHORT RANGE ENSEMBLES INDICATE AROUND
100 J/KG OF MUCAPE IN THESE AREAS...LEFT MENTION OF THUNDER OUT OF
THE FORECAST FOR NOW.

GUSTY SOUTHERLY WINDS ACROSS SOUTHEAST UTAH SHOULD ABAIT THIS
MORNING AS SURFACE BAROCLINIC ZONE MOVES EAST OF THE AREA. NO OTHER
CHANGES AT THIS TIME.

PREVIOUS DISCUSSION FOLLOWS...
THE COLD UPPER LOW REMAINS CENTERED OVER SRN CA THIS MORNING WITH AN
ACTIVE BAROCLINIC ZONE DRAPED N-S OVER UT. PRECIP HAS BEEN FAIRLY
WIDESPREAD UNDER THIS ZONE AND IT HAS BEEN HEAVY IN A FEW AREAS.

THE UPPER LOW IS STILL FORECAST TO START LIFTING NORTHEAST THIS
MORNING ENDING UP OVER E-CENTRAL UT BY MIDNIGHT TONIGHT. AS THE
SYSTEM STARTS TO MOVE...EXPECT PRECIP TO BECOME EVEN MORE
WIDESPREAD ACROSS THE CWA THRU THE MORNING THEN TAPER OFF FROM THE
SOUTHWEST BEGINNING LATE TODAY.

AN AREA OF WRAPAROUND PRECIP DEVELOPS ACROSS THE NORTH LATE TODAY
INTO THIS EVE...WITH A MOIST NORTHWEST FLOW TONIGHT INTO SUNDAY.
THIS WILL KEEP PRECIP GOING IN NW FLOW FAVORED AREAS THRU MUCH OF
THE NIGHT.

HAVE KEPT THE EXISTING WINTER WEATHER HIGHLIGHTS IN PLACE FOR THE
MTNS. STILL DONT SEE ALL THAT MUCH IMPACT FROM SNOW IN THE
VALLEYS AS MUCH OF IT CONTINUES TO MELT AS IT FALLS. IT IS
POSSIBLE THAT SNOW COULD COVER VALLEY ROADS FOR BRIEF PERIODS
DURING TIMES OF HEAVIER PRECIP BUT THIS SHOULD MELT OFF PRETTY
QUICKLY ONCE THE SNOW RATES DROP OFF. SO WILL NOT ISSUE ANY
HIGHLIGHTS FOR VALLEYS AT THIS TIME.

RIDGING BUILDS IN STRONGLY MON AS THE LOW MOVES OFF THE TO EAST
BUT LOW LEVEL MOISTURE IS FORECAST TO REMAIN IN PLACE UNDER
NORTHWEST FLOW AND LIGHT OROGRAPHICALLY INDUCED PRECIP COULD
CONTINUE ACROSS THE NORTH WELL INTO SUN.

THE RIDGE SHIFTS QUICKLY EAST MONDAY MAKING WAY FOR SEVERAL SHORT
WAVE TROFS TO CROSS THE GREAT BASIN WITH THE STRONGEST ONE FOR FOR
WED. NONE OF THESE ARE ALL THAT STRONG BUT WILL BRING A THREAT OF
PRECIP TO THE NORTHERN CWA MONDAY NIGHT/TUE THEN MOST OF THE CWA
WED.

&&

.AVIATION...AT THE SLC TERMINAL...LOW-END MVFR TO HIGH-END IFR
CONDITIONS IN SNOW ARE EXPECTED TO IMPROVE TO LOW-END VFR BETWEEN
15Z AND 16Z AS SNOW TAPERS OFF. HOWEVER...SNOW IS EXPECTED TO
REDEVELOP BETWEEN 18Z AND 19Z...ALLOWING CONDITIONS TO DETERIORATE
ONCE AGAIN. THERE IS A 30 PERCENT CHANCE THAT THE BREAK IN SNOW WILL
BE SHORTER THAN EXPECTED. NORTHWEST WINDS SHOULD CONTINUE THROUGHOUT
THE DAY.
