AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1031 AM MDT TUE SEP 21 2010

.SYNOPSIS...WARM AND DRY SOUTHWEST FLOW WILL RETURN TODAY AHEAD
OF THE NEXT PACIFIC DISTURBANCE. THE FLOW STRENGTHENS WEDNESDAY
AND MOISTURE WILL INCREASE FROM THE SOUTH. THE DISTURBANCE WILL
CROSS THE REGION WEDNESDAY NIGHT WITH DRIER WESTERLIES SPREADING
BACK INTO THE AREA THURSDAY.

&&

.DISCUSSION...UPSTREAM TROUGH APPROACHING WEST COAST THIS MORNING
PER REGIONAL WATER IMAGERY..WITH WESTERLY FLOW ACROSS THE GREAT
BASIN STATES SHOWING SIGNS OF BACKING PER 12Z OBSERVATIONAL
ANALYSIS. SHORT TERM GUIDANCE INDICATES SAID BACKING OF MID LEVEL
WINDS WILL CONTINUE THROUGH TODAY WITH SPEEDS GRADUALLY INCREASING
AS TROUGH PUSHES ON SHORE LATER THIS AFTERNOON. MSAS SURFACE
PRESSURE ANALYSIS INDICATES PRESSURE FALLS ACROSS THE NORTHWESTERN
THIRD OF UTAH...WITH RISES OCCURRING OVER THE SOUTHERN TIER OF THE
STATE. ANTICIPATE GRADIENT WILL ORIENT MORE SOUTHERLY THROUGH THE
DAY. THIS COUPLED WITH INCREASING WINDS ALOFT WILL CREATE BREEZY
SOUTHERLY WINDS THIS AFTERNOON AS BOUNDARY LAYER MIXES ALLOWING
MOMENTUM ALOFT TO TRANSLATE TO THE SURFACE.

SHORT WAVE RIDGING IN PLACE ACROSS THE STATE AHEAD OF SAID TROUGH
WILL MAINTAIN STABLE ENVIRONMENT WITH CLEAR SKIES AND TEMPS A
SOLID 5 TO 10 DEGREES ABOVE CLIMO FOR MOST LOCALS.

SURFACE DEWPOINTS ACROSS SOUTHERN AZ/CA SHOWING A MARKED INCREASE
THIS MORNING AS MONSOONAL MOISTURE BEGINS A NORTHWARD SURGE. 60S
THE NORM THERE...WITH EVEN A FEW ISOLATED 70 DEGREE VALUES PER
LATEST OBS. GUIDANCE CONTINUES TO TRANSLATE THIS SURGE NORTH INTO
SOUTHERN UTAH BY DAYBREAK WEDNESDAY...WITH PWATS PER GFS ENSEMBLE
FORECAST INDICATING +2 TO +4 STANDARD DEVIATIONS ABOVE
NORMAL. THIS COUPLED WITH GUIDANCE INDICATING A SOUTHERLY TRACK OF
AFOREMENTIONED TROUGH WEDNESDAY...DYNAMIC LIFT ASSOCIATED WITH
80-100KT JET ALOFT AND SOLID PVA ANTICIPATED TO KICK OFF SCATTERED
TO POSSIBLY NUMEROUS SHOWERS AND THUNDERSTORMS WITH POTENTIAL FOR
HEAVY RAIN AND TRAINING OF CELLS OVER SOUTHERN AND SOUTHEASTERN
UTAH. LEANING TOWARDS ISSUING A FLASH FLOOD WATCH FOR SOUTHEASTERN
AND POSSIBLY SOUTH CENTRAL UTAH LATER THIS SHIFT AFTER FULL REVIEW
OF 12Z RUNS.

NAM CONTINUES TO INDICATE MOISTURE GRADIENT WILL DRAPE ACROSS THE
WASATCH FRONT WEDNESDAY. AREAS EAST MORE LIKELY FOR CONVECTION AND
ASSOCIATED WETTING RAINS...BUT CONCERNS EXIST FOR HIGHER BASED
CONVECTION ALONG AND AHEAD OF THE MID LEVEL TROUGH AXIS LATE IN THE
AFTERNOON ACROSS NORTHERN/WESTERN UTAH. DRY LIGHTNING A THREAT IN
THIS SCENARIO.

NO UPDATES MADE OF PLANNED AT THIS TIME. PREVIOUS DISCUSSION FOLLOWS.

SIMULATED REFLECTIVITY FROM THE 00Z RUN OF THE 4KM WRF-NMM RUN
FOR SPC INDICATES WIDESPREAD RAIN/THUNDERSTORMS MOVING INTO
SOUTHERN UTAH FROM NORTHERN ARIZONA BY 12Z WEDNESDAY. INDICATE
ISOLATED ACTIVITY ACROSS SOUTHERN UTAH WITH BUILDING INSTABILITY
00Z-06Z TONIGHT...WITH HIGH END CHANCE POPS BY 12Z. USED
COMBINATION OF PRECIPITABLE WATER ANOMALY FROM 00Z GFS ENSEMBLE
FORECAST SYSTEM...AND INSTABILITY ADVERTISED FROM 21 SHORT RANGE
ENSEMBLES...TO PLACE LIKELY POPS ACROSS EASTERN FORECAST AREA
WEDNESDAY...TAPERING TO SLIGHT CHANCE WEST OF INTERSTATE 15. THIS
ACTIVITY IS EXPECTED TO TAPER OFF FROM WEST TO EAST WEDNESDAY
NIGHT WITH THE PASSAGE OF THE DISTURBANCE.

HEAVY RAIN IS POSSIBLE FROM THIS ACTIVITY PARTICULARLY EAST OF
INTERSTATE 15 AND SOUTH OF INTERSTATE 70...THOUGH INDIVIDUAL STORM
MOTIONS ARE FORECAST TO BE AROUND 30 MPH. WILL HAVE TO MONITOR FOR
TRAINING ACTIVITY AND POTENTIAL FLASH FLOODING.

HEIGHTS RECOVER LATE THIS WORK WEEK. BOTH THE EUROPEAN AND GFS
INDICATE A RIDGE DEVELOPS ACROSS THE SOUTHWEST CONUS NEXT
WEEKEND...STRENGTHENING EARLY NEXT WEEK. THIS SCENARIO WOULD TRAP
MOISTURE SOUTH OF THE AREA...WITH POTENTIAL FOR AFTERNOON AND
EVENING CONVECTION ACROSS FAR SOUTHERN UTAH EARLY NEXT WEEK SHOULD
THE RIDGE AXIS SHIFT FURTHER NORTH THAN CURRENTLY ADVERTISED.

&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS FROM CLEAR
SKIES TODAY. SOUTHEAST DRAINAGE WINDS THIS MORNING WILL TURN SOUTH
AND INCREASE AROUND 18Z. A 20 PERCENT CHANCE OF A LATE WIND SHIFT TO
THE NORTHWEST WILL EXIST BETWEEN 21-23Z.

&&

.FIRE WEATHER...INCREASING SW WINDS ALOFT WILL MIX DOWN TO THE
SURFACE THIS AFTERNOON...RESULTING IN GUSTY SOUTHERLY WINDS ACROSS
MOST FIRE DISTRICTS THROUGH THIS EVENING. THESE WINDS ALONG WITH
RAPIDLY DECREASING RH VALUES WILL RESULT IN HAZARDOUS FIRE
CONDITIONS THIS AFTERNOON THROUGH MIDEVENING ACROSS ALL BUT A FEW
FIRE DISTRICTS IN FAR NRN AND SE UTAH.

MOISTURE SURGING NORTH THROUGH AZ TODAY WILL MOVE ACROSS SRN AND ERN
UTAH TONIGHT THROUGH WEDNESDAY. AREAS OF WRN AND NRN UTAH ON THE
EDGE OF THE MOISTURE SURGE COULD EXPERIENCE LIGHTNING WITH SPOTTY
RAINFALL WEDNESDAY AFTERNOON/EVENING. AREAS UNDER THE MOISTURE SURGE
WILL SEE AN INCREASE IN LIGHT SHOWERS LATE TONIGHT...WITH SCATTERED
SHOWERS/THUNDERSTORMS ON WEDNESDAY. A NUMBER OF THE THUNDERSTORMS
ACROSS SRN THROUGH E/CNTRL UTAH WILL PRODUCE WETTING RAINS BY
AFTERNOON. FIRE WEATHER WATCH WILL BE IN EFFECT FOR PORTIONS OF
WRN/NRN UTAH WITH THE EMPHASIS ON LIGHTNING AFTER A PROLONGED DRY
PERIOD. THE REMAINDER OF THE FIRE DISTRICTS WILL ALSO BE UNDER A
WATCH DUE TO THE THREAT OF LIGHTNING WITH DRY FUELS...EVEN THOUGH RH
VALUES WILL BE UP AND WINDS GENERALLY BELOW CRITERIA.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...RED FLAG WARNING UNTIL 9 PM MDT THIS EVENING FOR
     UTZ420-423>427-431>440.
