AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1041 AM MST FRI MAR 8 2013

.SYNOPSIS...A STRONG UPPER LEVEL LOW WILL CROSS SOUTHERN
CALIFORNIA TODAY AND NORTHERN ARIZONA TONIGHT INTO SATURDAY. HIGH
PRESSURE WILL START TO BUILD BACK INTO THE AREA SUNDAY AND
GRADUALLY SHIFT OVER THE GREAT BASIN DURING THE WEEK.

&&

.DISCUSSION...COMPLICATED UPPER LEVEL TROUGH TO IMPACT THE STATE
THROUGH SATURDAY...MOST SIGNIFICANTLY AREAS SOUTH OF INTERSTATE
70. WATER VAPOR CONTINUES TO IDENTIFY TWO DISTINCT CIRCULATION
CENTERS WITHIN THE BROAD TROUGH ALONG THE PACIFIC COAST. THE MORE
PRONOUNCED OF THE TWO LOCATED OFF THE SOCAL COAST WILL CHURN EAST
ACROSS NORTHERN ARIZONA TONIGHT...WITH THE SECONDARY CIRCULATION
CENTER DUMBBELLING DOWN THE BACKSIDE AIDING THE FORMERS EASTWARD
PROGRESSION.

UPPER LEVEL DIVERGENCE CONTINUES TO INCREASE ACROSS THE SOUTH
THIS MORNING...KEY NOTE BEING RAPIDLY COOLING AND EXPANDING OF
CLOUD TOPS FROM SOUTH CENTRAL TO SOUTHWESTERN UTAH WEST THROUGH
SOUTHERN NEVADA. RAIN WITH SNOW OVER 6500FT OR SO IS THE RULE
ACROSS THE SOUTH AT THIS TIME...WITH SNOW ON MOUNTAIN ROADWAYS
PER WEB CAM IMAGERY. DEBRIS FROM THIS CONTINUES TO STREAM NORTH
BRINGING CLOUDY SKIES AND SOME LIGHT SHOWERS TO THE NORTH...BUT
NOTHING OF SIGNIFICANCE. UPDATED RECENTLY TO REMOVE LIKELY OR
HIGHER CHANCES FOR STEADY RAIN AND OR SNOW ACROSS THE NORTHERN
VALLEYS AS FORCING JUST IS NOT THERE...NO LIFT TO SPEAK OF...AND
TRUST IN GUIDANCE REGARDING PF LIMITED AT BEST AS BULK OF
GUIDANCE HAS FAILED TO CAPTURE REALITY THUS FAR. RETAINED LIKELY
POPS IN THE NORTHERN MOUNTAINS AS A HIGHER POP/LOW PF FORECAST
SEEMS WARRANTED AS LIMITED HEATING SHOULD INCREASE SHOWER
POTENTIAL THIS AFTERNOON.

FORECAST CHALLENGE OF THE SHIFT ONGOING WILL BE TAKING A HARD LOOK
AT WINTER WEATHER HIGHLIGHTS FOR THE SOUTHERN MOUNTAINS AND
ADJACENT VALLEYS...SPECIFICALLY FOR THE OVERNIGHT AND EARLY
SATURDAY MORNING PERIOD. MAY NEED TO UPGRADE GOING ADVISORY IN THE
SOUTHERN MOUNTAINS TO A WARNING...AND ADD ADVISORIES TO SOME
VALLEYS ABOVE 5/5500FT ACROSS SOUTH CENTRAL UTAH. NOT BASING THIS
OFF OF SPECIFIC RUN TOTAL PF PER SE AS RUN TO RUN AND MODEL TO
MODEL CONSISTENCY HAS BEEN POOR. RATHER DECISION WILL BE MADE
REGARDING CONFIDENCE IN DYNAMIC FORCING OF TROUGH OVER NEXT 24
HOURS...STRENGTH OF 700MB CONVERGENCE COUPLED WITH DIVERGENCE ALOFT
(PEAKING TONIGHT)...TRACK OF 700MB CIRCULATION...AND POTENTIAL FOR
ENHANCEMENT ALONG THE NORTH SIDE OF THE COLD POOL AS STRONG
UPGLIDE LOOKS LIKELY LATE TONIGHT INTO THE EARLY MORNING. HIGHER
PI POTENTIAL SHOULD PROMOTE LOWER THAN EXPECTED SNOW LEVELS.

TRENDING MORE AND MORE TOWARDS A NON EVENT IN THE NORTH...THOUGH
PRECIP POTENTIAL WILL PEAK TONIGHT INTO SATURDAY MORNING AS MID
LEVEL CIRCULATION TRACKS THROUGH CENTRAL UTAH. SHOULD REALIZE
RAPID DRYING NW- SE TOMORROW AFTERNOON WITH PASSAGE OF THIS
FEATURE. AGAIN...BEST APPROACH MOVING FORWARD IS RUNNING WITH A
HIGH SIDE POP LOW QPF FORECAST IN THE NORTH WITH MINIMAL SNOW IN
THE WASATCH.

SIDE NOTE...MAY NEED TO ADD LIGHTNING ACROSS THE SOUTH IN THE
AFTERNOON PACKAGE AS ELEVATED INSTABILITY WILL BE ON THE RISE. FOR
NOW CONVECTIVE POTENTIAL REMAINS TO THE SOUTH WITH CELLULAR
DEVELOPMENT FOCUSED SOUTH AND EAST OF VEGAS. WILL MONITOR.

&&

.AVIATION...WINDS AT THE SLC TERMINAL WILL REMAIN FROM THE NORTH
THROUGH THE FORECAST PERIOD. CIGS WILL DROP TO AROUND 6000FT BETWEEN
21 AND 23Z...THOUGH THERE IS A 20 PERCENT CHANCE THAT CIGS BELOW
6000FT WILL HOLD OFF UNTIL 00Z. LIGHT RAIN SHOWERS ARE POSSIBLE
AFTER 01Z...BUT WILL NOT RESTRICT VISIBILITIES. MVFR CONDITIONS WILL
DEVELOP AFTER 6Z IN A RAIN/SNOW MIX.

&&
