THE STRONG WINDS WILL CREATE DANGEROUS BOATING CONDITIONS ON AREA
LAKES. THESE WINDS WILL CREATE VERY CHOPPY WATER AND GENERATE
LARGE WAVES WHICH COULD CAPSIZE OR SWAMP SMALL CRAFT. FOR YOUR
PERSONAL SAFETY...OPERATORS OF SMALL CRAFT ARE URGED TO POSTPONE
THEIR OUTINGS UNTIL THE WINDS SUBSIDE.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
801 PM MDT THU MAY 20 2010

.SYNOPSIS...A COLD FRONT ACROSS CENTRAL UTAH THIS EVENING WILL
RETURN NORTHWARD ACROSS NORTHERN UTAH AND SOUTHWEST WYOMING
FRIDAY. THE NEXT STORM SYSTEM WILL IMPACT THE REGION THIS WEEKEND
AND INTO EARLY NEXT WEEK.

&&

.DISCUSSION...WATER VAPOR LOOP SHOWS A TROUGH DOMINATING THE PACIFIC
NORTHWEST AND GREAT BASIN. THE FIRST DISTURBANCE PIN-WHEELED NORTH
INTO SOUTHERN ALBERTA...WHILE THE CENTER OF THE BROAD CIRCULATION
REMAINS OFF THE BRITISH COLUMBIA COAST. 400-250MB ACARS WIND
OBSERVATIONS A 90-110KT CYCLONICALLY CURVED JET ACROSS NORTHERN
CALIFORNIA...NEVADA AND SOUTHERN IDAHO. 00Z 700MB ANALYSIS SHOWS A
COLD FRONT WHICH HAS STALLED ACROSS CENTRAL NEVADA AND NORTH CENTRAL
UTAH. LITTLE THERMAL CHANGE IS OCCURRING LOCALLY WITH 0C AT KSLC AND
UPSTREAM AT KRIW. 00Z KSLC RAOB SHOWS 3C OF COOLING THROUGH THE
COLUMN EXCEPT SLIGHT WARMING NEAR 700MB DURING THE PAST 24 HOURS.

GOES/RUC PRECIPITABLE WATER INDICATE VALUES VARY FROM A THIRD TO
HALF INCH ACROSS THE STATE.

IR/VISIBLE SATELLITE SHOWS THE DEVELOPMENT OF SHOWER ACTIVITY ALONG
THE NEVADA BORDER IN CENTRAL UTAH. A SUBTLE SHORT WAVE IS CURRENTLY
MOVING OVER THAT AREA AND IS FORECAST BY THE MODELS TO LIFT
NORTHEAST OF THE REGION LATE THIS EVENING...THUS ENDING
AFOREMENTIONED CONVECTIVE ACTIVITY. OTHERWISE...ISOLATED SHOWER
ACTIVITY WILL LIKELY OCCUR IN THE NORTHERN MOUNTAINS AND UINTAS AS
THE SHORT WAVE ROTATES THROUGH EARLY TONIGHT. RE-DEFINED POPS IN
THE NORTHERN MOUNTAINS.

OTHERWISE LOWERED OVERNIGHT LOWS NORTH OF THE BOUNDARY AND RAISED
THEM SOUTH OF THE BOUNDARY BASED ON CURRENT OBSERVATIONAL TRENDS AND
LATEST MODEL GUIDANCE.

LOOKING AHEAD TO TOMORROW...700MB FLOW BECOMES QUITE STRONG BY LATE
AFTERNOON ACROSS SOUTHERN UTAH. NEXT SHIFT WILL LIKELY HAVE TO RAISE
SOME WINDS HEADLINES. ALSO...WITH 21Z SHORT RANGE ENSEMBLES
INDICATING 30-40KTS OF EFFECTIVE BULK SHEAR ACROSS NORTHERN UTAH AND
SOUTHWEST WYOMING...CONVECTIVE DEVELOPMENT ALONG LIFTING WARM FRONT
MAY BECOME STRONG OR SEVERE DURING THE AFTERNOON.

PREVIOUS DISCUSSION FOLLOWS...

BROAD TROUGH TAKING FROM IN THE EASTERN PACIFIC/WESTERN CONUS PER
WATER VAPOR. A STRENGTHENING UPPER JET OF 140-160KTS RESIDES ON THE
BACK EDGE OF THE TROUGH WEST OF 130W AND WILL AID IN DEEPENING THE
LONG WAVE OFF THE WEST COAST. THE SHORT WAVE TROUGH RESPONSIBLE FOR
SURGING A WEAK COLD FRONT THROUGH NORTHERN UTAH THIS MORNING IS
RACING OFF TO THE NORTHEAST ATTM...AND THE ASSOCIATED SHOWER
ACTIVITY IS WANING OVER THE FAR NORTH.

OBSERVATIONAL ANALYSIS NOW PLACES THE WEAK COLD FRONT ON A LINE
FROM DELTA TO DUCHESNE...ANTICIPATE LITTLE IF ANY SOUTHWARD
PROGRESSION FROM THIS POINT ON TODAY. AS THE TROUGH CONTINUES TO
DEEPEN ALONG THE WEST COAST TONIGHT AND FRIDAY THIS BOUNDARY WILL
LIFT TO THE NORTH BEFORE STALLING OVER NORTHERN UTAH BY MIDDAY.
YET ANOTHER SHORT WAVE WILL RACE THROUGH NEVADA/STHRN IDAHO FRIDAY
AFTERNOON TIGHTENING AND SURGING THIS BOUNDARY BACK INTO
CENTRAL/SOUTHERN UTAH INTO THE OVERNIGHT HOURS.

NAM/GFS SUPPORT A LIKELY WIND ADVISORY OVER SOME VALLEY AREAS OF
THE SOUTH FRIDAY AFTERNOON/EVENING AS SOUTHWESTERLY FLOW AHEAD OF
THE FRONT WILL RAMP UP SIGNIFICANTLY (30 TO 50KTS) DURING THAT
TIME. PEAK 700 WINDS MAY VERY WELL OCCUR THROUGH THE MIDDLE OF THE
NIGHT...BUT DIURNAL TRENDS AND DECOUPLING WILL LIKELY LIMIT FULL
SURFACE POTENTIAL AT THAT TIME.

ADDITIONAL TO THE WINDS...A THREAT FOR CONVECTION EXISTS ACROSS
NORTHERN AND CENTRAL UTAH FRIDAY AFTERNOON AND EVENING. SPC SREF
SHORT RANGE ENSEMBLES INDICATE 30 TO 40 KTS EFFECTIVE SHEAR FROM
THE NORTHERN WASATCH PLATEAU NORTHEAST INTO SOUTHWESTERN
WYOMING...AND NAM BUFKIT PRODUCE CAPE NEAR AND ABOVE 500 J/KG AT
KPUC. THIS COUPLED WITH PWATS OF .5-.6 INCHES SUPPORT AT LEAST A
THREAT OF A FEW ORGANIZED THUNDERSTORMS ORIGINATING OVER THE
MOUNTAINS IN THAT REGION. HAVE ADDED WORDING OF SMALL HAIL POTENTIAL
IN THOSE ZONES TO ACCOUNT FOR THIS THREAT. NORTH AND SOUTH OF THAT
AREA INSTABILITY AND OR MOISTURE WANES...THOUGH A SOLID THREAT FOR
CONVECTIVE SHOWERS WILL EXIST OVER THE NORTH THROUGH SATURDAY
MORNING...LIKELY INCREASING IN AREAL COVERAGE AS THE NOSE OF A 100KT
JET SWINGS IN ALOFT OVER NORTHWESTERN UTAH LATE NIGHT INTO THE
MORNING HOURS.

FRONTAL BAROCLINICITY WILL BE THE FOCUS OF PRECIP GENERATION
THROUGH THE WEEKEND. THE DEEPENING TROUGH ALONG THE WEST COAST
WILL CLOSE OFF (SOLID EC/GFS AGREEMENT) AND ORIENT MUCH OF THE
STATE UNDER MEAN SOUTHERLY FLOW. MULTIPLE SHORT WAVES EJECTING
WEST/NORTH OF THE STATE WILL PERIODICALLY NUDGE THIS BOUNDARY
SOUTH THROUGH SUNDAY...BUT THESE SHOULD BE ONLY GLANCING BLOWS AND
TIMING REMAINS DIFFICULT AT THIS TIME. PRECIP POTENTIAL DOES LOOK
AS STOUT AS THE LAST FEW DAYS...LIKELY ONLY ISOLATED TO SCATTERED
CONVECTION FOCUSING OVER NORTHERN UTAH.

GLOBAL MODELS SUGGEST THE SIGNIFICANT AND WIDESPREAD PRECIP LOOKS
TO HOLD OFF UNTIL LATE SUNDAY NIGHT/MONDAY. AT THAT TIME THE
CLOSED LOW WILL SWING SOUTHWEST TO NORTHEAST THROUGH THE STATE
BRINGING WIDESPREAD AND POTENTIALLY HEAVY PRECIP. SEVERE
WEATHER...THOUGH NOT A SLAM DUNK...MAY BE POSSIBLE AS
SHEAR/PVA/MOISTURE WILL BE ELEVATED. MORE DETAILS TO COME ON THIS
AS TIME PROGRESSES.

AND YES...AFTER BRIEF RIDGING TUESDAY THROUGH THURSDAY...YET
ANOTHER DEEP TROUGH WILL BE CARVING THROUGH THE GREAT BASIN LATE
WEEK NEXT WEEK. WIDESPREAD UNSETTLED WEATHER LOOKS LIKELY FOR THE
HOLIDAY WEEKEND...WHAT A WAY TO USHER IN THE SUMMER MONTHS.

&&

.AVIATION...NORTHERLY GRADIENT ACROSS NORTHERN UTAH SUFFICIENT
ENOUGH TO KEEP NORTH WINDS AT SLC TERMINAL THROUGH TONIGHT. THERE IS
ABOUT A 30 PERCENT CHANCE OF A SWITCH TO SOUTHEAST BETWEEN 11 AND
15Z. LOOK FOR CIGS TO LOWER ONCE AGAIN LATE FRIDAY MORNING...WITH A
40 PERCENT CHANCE OF SHOWERS...AND A 10 PERCENT CHANCE OF
THUNDERSTORMS DIRECTLY IMPACTING TERMINAL OPERATIONS AFTER 17Z.

&&

.FIRE WEATHER...THE BROAD UPPER LEVEL TROUGH APPROACHING THE WEST
COAST WILL GENERATE AN INCREASINGLY STRONG AND DRY SOUTHWEST FLOW
ACROSS UTAH ON FRIDAY. THE RESULTANT STRONG SOUTHERLY SURFACE WINDS
AND LOW RH VALUES WILL CREATE LOCAL HAZARDOUS FIRE WEATHER
CONDITIONS...THOUGH FINE FUELS STILL REMAIN IN THE GREEN-UP STAGE.

COOLER TEMPS/HIGHER RH VALUES WILL WORK INTO THE FIRE DISTRICTS AS
THE WEST COAST TROUGH MOVES INTO THE WRN GREAT BASIN THIS WEEKEND.
LOOKING AT AN INCREASING THREAT OF PRECIP BOTH DAYS...WITH MOST OF
THE ACTIVITY CONFINED TO THE WRN/NRN PORTIONS OF THE STATE. THE BEST
THREAT OF PRECIP WILL COME SUNDAY NIGHT/MONDAY THE TROUGH LIFTS NE
THROUGH THE BASIN ON ITS WAY TO THE NRN ROCKIES. WIDESPREAD PRECIP A
