AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
350 PM MST WED JAN 11 2006
.SYNOPSIS...A PACIFIC STORM SYSTEM WILL MOVE ACROSS UTAH AND
SURROUNDING AREAS TONIGHT AND EARLY THURSDAY. THIS SYSTEM WILL BRING
WIDESPREAD PRECIPITATION TO THE MOUNTAINS AS WELL AS TO MANY VALLEY
LOCATIONS TONIGHT. THE STORM WILL SHIFT EAST OF THE AREA THURSDAY
MORNING AS HIGH PRESSURE BUILDS INTO THE GREAT BASIN. THE NEXT
STORM IS EXPECTED TO IMPACT THE AREA OVER THE WEEKEND.
&&
.DISCUSSION...PACIFIC STORM TO IMPACT NORTHERN UTAH TONIGHT THROUGH
THURSDAY MORNING. THIS SYSTEM HAS LOOKED PROGRESSIVELY LESS
IMPRESSIVE WITH TIME. HOWEVER...SYSTEM STILL EXHIBITS STRONG UPPER
LEVEL DIVERGENCE THIS EVENING ON NOSE OF 130 KT JET WHICH SUPPORTS
DEEP THERMALLY INDIRECT CIRCULATION. THIS IS COUPLED WITH MID LEVEL
FRONTOGENETICAL FORCING ASSOCIATED WITH TIGHTENING THERMAL RIBBON AT
700MB. THIS LEADS TO DEEP VERTICAL MOTION THIS EVENING AS UPPER AND
LOWER LEVEL FORCING COINCIDE FOR SEVERAL HOURS. INSTABILITY WILL BE
NOT BE EXCEPTIONALLY DEEP AS 500 MB COLD POOL BRUSHES NORTHERN UTAH
WITH THE CORE OF THE -30C AIR CONFINED TO SOUTHERN IDAHO. ALTHOUGH
NOT PARTICULARLY DEEP THE CONVECTIVE INSTABILITY COINCIDES WITH THE
BEST FORCING AND THEREFORE WE SHOULD SEE GOOD RESPONSE TO THE DEEP
FORCING DURING THE EVENING HOURS INTO THE EARLY OVERNIGHT PERIOD.
THIS SHOULD RESULT IN GOOD SNOWFALL RATES IN THE NORTHERN MOUNTAINS.
THE DEEP OMEGA IS RELATIVELY SHORT LIVED WHICH WILL LIMIT TOTAL
ACCUMULATIONS WITH THIS SYSTEM. WILL KEEP WARNINGS GOING AT THIS
TIME ALTHOUGH BELIEVE THAT SNOWFALL AMOUNTS WILL BE ON THE LOW END
OF CRITERIA. STILL ANTICIPATE STRONG WINDS WITH THE MID LEVEL
TROUGH WHICH WILL LEAD TO CONSIDERABLE BLOWING AND DRIFTING SNOW IN
THE HIGHER TERRAIN.
MOST VALLEY LOCATIONS ACROSS NORTHERN UTAH WERE WELL MIXED TODAY AND
TEMPERATURES CLIMBED INTO THE 50S IN MANY AREAS. EVENT WILL CLEARLY
BEGIN AS RAIN IN VALLEY LOCATIONS AS THESE WARM TEMPERATURES WILL
INITIALLY BE TOUGH TO OVERCOME. HOWEVER...LARGE SURFACE DEWPOINT
DEPRESSIONS WILL ALLOW FOR RAPID EVAPORATIONAL COOLING AT THE ONSET
OF PRECIPITATION. EVEN CONSIDERING WET BULB EFFECTS AT PRECIPITATION
ONSET BELIEVE THAT IT MAY TAKE AWHILE TO CHANGE OVER TO SNOW IN SOME
VALLEY LOCATIONS. ALREADY SEEING SOME SNOW IN THE CACHE VALLEY AS
TEMPERATURES HAVE DROPPED INTO THE MID 30S THERE. BELIEVE THAT THE
CACHE IS THE VALLEY MOST LIKELY TO FLIRT WITH ADVISORY CRITERIA
TONIGHT ALTHOUGH BELIEVE THAT PRIMARY LOW LEVEL FORCING WILL SHIFT
SOUTH BEFORE IT GETS OUT OF HAND. BEHIND THE FRONT...WHICH WILL
SWEEP DOWN THE WASATCH FRONT THIS EVENING...WE WILL SEE THE RAIN MIX
WITH AND EVENTUALLY CHANGE TO SNOW IN MANY LOCATIONS. THE LATER
ONSET OF SNOW AND THE WARM GROUND TEMPERATURES WILL LIMIT POTENTIAL
ACCUMULATIONS IN NORTHERN UTAH VALLEYS AND WILL CONTINUE WITH
THINKING OF ONLY AN INCH OR TWO IN THE NORTHERN VALLEYS. TOMORROW
MORNING THE INSTABILITY DECREASES FAIRLY RAPIDLY AS HIGH PRESSURE
BUILDS INTO THE GREAT BASIN.
MEDIUM RANGE MODELS INDICATE THAT THE PATTERN WILL REMAIN QUITE
ACTIVE THROUGH THE MIDDLE OF NEXT WEEK. ECMWF AND GFS IN DECENT
AGREEMENT ON THE EVOLUTION OF THE LARGE SCALE PATTERN THROUGH THE
WEEKEND. SHARP UPPER LEVEL RIDGE BUILDS INTO THE GREAT BASIN LATE
THU AND FRI AHEAD OF DEEPENING TROUGH WHICH MOVES ONTO THE WEST
COAST OVER THE WEEKEND. THIS TROUGH LOOKS MUCH DEEPER AND HAS THE
POTENTIAL TO BRING DECENT MOUNTAIN SNOW TO BOTH NORTHERN AND AND
SOUTHERN UTAH. GIVEN THE SHARPNESS OF THE TROUGH THIS SYSTEM SHOULD
HAVE A MUCH BETTER COLD POOL ASSOCIATED WITH IT. MODELS EVEN
INDICATE SOME NEVADA CYCLOGENESIS WITH THIS SYSTEM. WILL CONTINUE
WITH IDEA OF HIGHER POPS IN THE SUNDAY TIME FRAME WITH THIS STORM AT
THIS TIME.
&&
.AVIATION...COLD AIRMASS DROPPING INTO NRN UTAH BEHIND COLD FRONT
TONIGHT. AREAS OF SNOW WILL CONTINUE ALONG THE WASATCH FRONT
THROUGH 06Z. WITH COLD AIR SETTLING OVER NORTHERN UTAH ON NORTHWEST
FLOW TONIGHT THE PRECIPITATION WILL BE HEAVIEST SOUTHEAST OF THE
GREAT SALT LAKE. WIDESPREAD MVFR CEILINGS WILL REMAIN THROUGH THE
NIGHT WITH LOCAL IFR CEILINGS AND VISIBILITIES EXPECTED THROUGH AT
LEAST 03Z.
