AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
900 PM MDT WED APR 5 2006
.SYNOPSIS...A COLD AND MOIST STORM SYSTEM WILL BE OVER THE AREA
TONIGHT THROUGH THURSDAY. WARMER HIGH PRESSURE RETURNS FOR FRIDAY
THROUGH THE WEEKEND.
&&
.DISCUSSION...SCATTERED SHOWERS CONTINUE OVER MUCH OF NORTHERN UTAH
AND PARTS OF SOUTHERN UTAH THIS HOUR IN THE UNSTABLE AND DRIER AIR
MASS UNDER SOUTHWEST FLOW ALOFT. EARLIER A LINE OF SHOWERS AND
THUNDERSTORMS...STRONGEST NORTHERN WASATCH FRONT...MOVED ACROSS THE
NORTHERN VALLEYS. THIS CONVECTION OCCURRING IN THE COLD POOL ALOFT
OF THE MAIN UPPER LOW CIRCULATION THAT IS NOW OVER FAR NORTHEAST
NEVADA. THIS LOW WILL DRIFT EAST ALONG THE IDAHO BORDER AND INTO
SOUTHWEST WYOMING BY SUNRISE THURSDAY.
DEEP LAYER MOISTURE ON THE BACK SIDE OF THE SYSTEM WILL SEND
WIDESPREAD PRECIPITATION ACROSS THE DESERTS AND INTO THE WASATCH
FRONT LATER THIS EVENING AND ESPECIALLY AFTER MIDNIGHT. THIS ALREADY
EVIDENT ON RADAR LOOPS. MEAN FLOW WILL VEER TO THE WEST AFTER
MIDNIGHT AND THEN NORTHWEST TOWARD SUNRISE. THE STEADY AND
OCCASIONALLY HEAVY PRECIPITATION WILL BANK UP ALONG THE WASATCH
FRONT BUT PLENTY DEEP ENOUGH TO SPILL INTO THE WASATCH BACK AND WITH
700 MB TEMPERATURES NEAR -8C THE BOUNDARY LAYER AND DEWPOINT
DEPRESSIONS OF SEVERAL DEGREES SHOULD ALLOW ENOUGH COOLING IN THE
STEADY PRECIPITATION TO BRING SNOW DOWN TO THE VALLEY FLOOR AFTER
MIDNIGHT. FLOW AT 700 MB WILL INCREASE TO 50 KNOTS OVER THE GREAT
SALT LAKE EARLY THURSDAY AND LOW TO MID LEVEL FLOW WILL CREATE
OROGRAPHIC UPSLOPE ALONG THE WASATCH RANGE. VORT LOBE BEHIND THE
MAIN UPPER LOW COMBINED WITH A DEEP MOISTURE LAYER WITH WARMING
ABOVE 700 MB IN WARM AIR ADVECTION WILL CREATE DEEP UPWARD MOTION.
THIS WILL BE AN EFFICIENT PRECIPITATION PRODUCER THROUGH THURSDAY
MORNING...AND LIKELY INTO THE AFTERNOON.
THE SOUTHERN PORTION OF THIS LIFT AND MOIST LAYER REACHES DOWN THE
I-15 CORRIDOR AND INTO THE SEVIER AND SANPETE VALLEYS LATE TONIGHT
AND THURSDAY MORNING. THESE AREAS SHOULD GET COLD ENOUGH IN THE
STEADY PRECIPITATION NEAR SUNRISE TO GET A COUPLE INCHES OF
SNOW...ESPECIALLY HIGHER VALLEY TERRAIN. A SECONDARY VORT LOBE IS
PROGGED TO ARRIVE MIDDAY THURSDAY WHICH SHOULD KEEP PRECIPITATION
CONTINUING ALONG THE WASATCH FRONT AND RANGE INTO THE CENTRAL
MOUNTAINS AND WESTERN UINTAS. PRECIPITATION WILL LIKELY BEGIN TO MIX
WITH RAIN ON THE VALLEY FLOOR IF A BREAK OCCURS BEHIND THE FIRST
VORT LOBE IN THE EARLY MORNING. NAM SUGGESTS CYCLONIC FLOW CONTINUES
THURSDAY EVENING FOR SCATTERED WASATCH FRONT PRECIPITATION IN
NORTHERLY FLOW AS THE LOW CONTINUES TO SHIFT EAST TO SOUTHEAST.
ACCUMULATING SNOW SHOULD CONTINUE IN THE EVENING FOR THE WASATCH
MOUNTAINS AND MOUNTAIN VALLEYS INTO THE UINTA MOUNTAINS.
SNOW TOTALS WILL BE SIGNIFICANT ON THE BENCHES AND THE NORTHERN
MOUNTAINS. WINTER STORM WARNING FOR MOUNTAINS COVERS THIS WELL AND
CONSIDERING SNOW RATIOS CLIMBING ABOVE 12 TO 1 WITH A REASONABLE 2
INCHES OF WATER FOR FAVORED UPSLOPE AREAS OF THE WASATCH RANGE. THE
WASATCH MOUNTAIN VALLEYS AND BENCHES HOWEVER MAY GET INTO WARNING
CRITERIA SNOW BETWEEN MIDNIGHT AND NOON THURSDAY...EVEN WITH SNOW
RATIOS BELOW 10 TO 1. WILL CONSIDER UPGRADE. GIVEN SYNOPTIC FORCING
PRECIPITATION WILL BE HEAVY BACK INTO THE DUGWAY AREA AS
WELL...THOUGH HIGHEST TOTALS WILL BE THE EAST SIDE BENCHES.
SHORT WAVE RIDGE PROGGED FOR FRIDAY STILL...AND AIR MASS WARM
SIGNIFICANTLY AS SOUTH FLOW DEVELOPS. 700 MB TEMPERATURES REACH
ABOUT -1C OVER THE GREAT SALT LAKE. SHORT WAVE TROUGH FOR FRIDAY
NIGHT PROGGED TO BRUSH FAR NORTHERN UTAH BUT LIFT TO THE NORTH. THIS
PUSHES A BOUNDARY NEAR THE RAFT RIVER RANGE OF FAR NORTHWEST UTAH ON
SATURDAY. THIS BOUNDARY MAY BECOME ACTIVE ON SUNDAY AS THE NEXT
UPPER TROUGH BACKS THE FLOW AND INCREASES LIFTS OVER NORTHEAST
NEVADA...BUT THIS KEEPS MOST OF UTAH IN THE DRIER AND MILD SECTOR.
NEXT UPPER TROUGH AND ASSOCIATED COLD FRONT WOULD THEN ARRIVE IN
UTAH FOR MONDAY FOR MORE WIDESPREAD PRECIPITATION.
&&
.HYDRO...RIVERS OF NORTHEAST UTAH APPEAR TO HAVE TOPPED OUT.
SNOWFALL TONIGHT AND THURSDAY WILL REDUCE RUNOFF BUT RAPID LOW
ELEVATION SNOWMELT FRIDAY THROUGH THE WEEKEND WILL BRING MORE RISES
TO THESE RIVERS. IN SOUTHWEST UTAH RISES OCCURRED ON THE UPPER
VIRGIN BUT HAVE STOPPED. ONLY SCATTERED SHOWERS AND MUCH LOWER SNOW
LEVELS EXPECTED IN THIS AREA TONIGHT. STORM TOTAL PRECIPITATION WAS
MOSTLY UNDER AN INCH IN SOUTHWEST UTAH SO RUNOFF HAS BEEN LESS THIS
STORM. AN SLCESFSLC PRODUCT WAS ISSUED EARLIER.
&&
.AVIATION...REINFORCING COLD FRONT WILL REACH SLC AT APPROXIMATELY
10Z...THOUGH WIND SHIFT WILL BE VERY GRADUAL. SOME SOUTHERLY
COMPONENT TO SURFACE FLOW WILL LIKE PERSIST UNTIL AROUND 12Z. SOME
CONCERN REMAINS WITH RESPECT TO VISIBILITIES FROM 09Z ON. MOISTURE
AND TEMPERATURE PROFILES SUGGEST A SWITCH OVER TO ALL SNOW BY AROUND
10Z. CURRENT TAF FORECAST VISIBILITY OF 1 MILE WITH SNOW LOOKS
REASONABLE...BUT MAY BE TO OPTIMISTIC WITH A PERIOD OF MODERATE SNOW
POSSIBLE BETWEEN 12Z AND 18Z. FINAL CONCERN IS FOR SNOW AND MVFR
CONDITIONS TO PERSIST BEYOND WHAT IS CURRENTLY IN TAF...BUT WILL
LOOK AT NEW GUIDANCE BEFORE ADJUSTING WITH NEXT TAF ISSUANCE.
