AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1024 AM MDT WED AUG 5 2009

.SYNOPSIS...A LOW PRESSURE SYSTEM OFF THE CALIFORNIA COAST THIS
MORNING WILL MOVE INLAND EARLY THURSDAY. DEEP SOUTHERLY FLOW
AHEAD OF THE APPROACHING LOW WILL DRAW MOISTURE INTO UTAH AND
PRODUCE STRONG SOUTHERLY SURFACE WINDS TODAY THROUGH THURSDAY. COOLER
TEMPERATURES WILL SPREAD ACROSS THE STATE FRIDAY THROUGH SATURDAY.

&&

.DISCUSSION...LITTLE CHANGE IN THE LARGE SCALE PATTERN IN THE LAST
SEVERAL DAYS AS HIGH PRESSURE REMAINS CENTERED OVER NEW
MEXICO...AND THE CLOSED LOW CONTINUES TO SPIN OFF THE PACIFIC
COAST. REGIONAL WATER VAPOR LOOP DOES REFLECT THE UPPER LOW MAKING A
SLIGHT JOG ONSHORE THIS MORNING...THUS BEGINNING ITS SLOW
PROGRESSION EASTWARD THROUGH THE GREAT BASIN OVER THE NEXT TWO AND
A HALF DAYS.

DEEP SOUTHWESTERLY FLOW REMAINS IN PLACE ACROSS THE
FORECAST REGION AND HAS FINALLY STARTED TAPPING INTO PLUME OF
MOISTURE THAT THUS FAR THIS WEEK HAS REMAINED PINNED TO THE HIGH
WELL SOUTH OF THE STATE. GOES PWAT ESTIMATES IDENTIFY A REGION OF
NEAR 1 INCH VALUES ROUNDING THE WESTERN EDGE OF THE HIGH POISED
TO SURGE INTO SOUTHWESTERN UTAH LATER THIS MORNING...AND
POTENTIALLY NORTHERN UTAH BY LATE THIS AFTERNOON AND EVENING. A
FINE LINE EXISTS BETWEEN DRY/MOIST ALONG THE UTAH/NEVADA
BORDER...BUT 12Z NAM/GFS BOTH SPARK CONVECTIVE DEVELOPMENT AS FAR
NORTH AS THE NORTHWEST DESERTS/WASATCH FRONT THROUGH THIS EVENING
COINCIDENT WITH THIS SURGE. THAT SAID...BONE DRY LOW LEVELS COMBINED
WITH INCREASING SOUTHERLY FLOW BOTH AT THE SURFACE AND ALOFT ALL
POINT TOWARDS MICROBURST WIND POTENTIAL WITH ANY BUILDUPS THAT DO
OCCUR THROUGH THIS EVENING. 12Z KSLC SOUNDING SHOWS A PRONOUNCED
INVERTED V SIGNATURE AS EXPECTED AND HAS TRENDED UP IN MOISTURE
OVER THE LAST 12 HOURS WITH .72 INCHES LOCALLY...SUPPORTING THIS
THREAT.

ON A BROADER SCALE...DRY SOUTHERLY WINDS WILL CONTINUE TO RAMP UP
THROUGH THURSDAY AHEAD OF AN ABNORMALLY STRONG AUGUST COLD FRONT.
SEVERE FIRE WEATHER CONDITIONS ARE EXPECTED TO DEVELOP AS A
RESULT...STARTING OVER WESTERN UTAH THIS AFTERNOON AND SPREADING
EAST ACROSS MUCH OF THE STATE THROUGH THURSDAY. REFER TO LATEST FIRE
WEATHER PRODUCTS FOR MORE DETAIL ON THIS THREAT. ADDITIONALLY...WIND
SPEEDS WILL LIKELY RAMP UP ENOUGH ON THURSDAY TO WARRANT ADVISORY
HEADLINES ACROSS AT LEAST THE PRONE SOUTHERLY WIND ALLEYS ACROSS
THE WESTERN PORTIONS OF THE STATE. WILL BE MONITORING THIS THREAT
IN LATER SHIFTS. DUE TO THE BREADTH AND STRENGTH OF THIS WIND
EVENT...AIR SHOULD BECOME INCREASINGLY HAZY THROUGH THURSDAY DUE
TO BLOWING DUST PACKED AHEAD OF THE COLD FRONT. COLD FRONTAL PASSAGE
THURSDAY EVENING SHOULD SCOUR MUCH OF THIS OUT WEST TO EAST WHILE
KNOCKING TEMPS DOWN BY 15 DEGREES AT LEAST FOR FRIDAY.

UPDATED TO CHANGE WORDING TO THUNDERSTORM COVERAGE IN THIS
MORNINGS PACKAGE...OTHERWISE NO CHANGES MADE NOR PLANNED AT THIS
TIME. PREVIOUS DISCUSSION FOLLOWS.....

THE COASTAL CA UPPER LOW STILL ON TRACK TO MOVE EAST INTO NRN CA
LATE TONIGHT...THEN EAST INTO THE WRN GREAT BASIN TONIGHT. FROM
THERE THE UPPER LOW WILL SLOWLY WIND DOWN AS IT LIFTS E-NE ACROSS
THE NRN GREAT BASIN/NRN ROCKIES FRIDAY THROUGH FRIDAY NIGHT. THE
ASSOCIATED SURFACE FRONT IS AGAIN RUNNING WELL AHEAD OF THE UPPER
LOW IN THE MODEL GUIDANCE FROM THE 00Z RUN. THE FRONT IS NOW
SCHEDULED TO CROSS WRN/NRN UTAH THURSDAY EVENING...WITH THE
REMNANT OF THE UPPER LOW FOLLOWING FRIDAY. LIMITED MOISTURE AND
MARGINAL BAROCLINIC STRUCTURE NOTWITHSTANDING...COULD STILL SEE
THIS SYSTEM PRODUCING AT LEAST SCATTERED CONVECTIVE PRECIP ACROSS
THE NRN THIRD OF THE STATE FRIDAY THROUGH EARLY FRIDAY. DECENT
DYNAMIC LIFT AND DEEP LAYER UNSEASONABLY COLD AIR ALOFT SUGGEST
THAT THIS SYSTEM COULD PRODUCE RESPECTABLE UPWARD MOTIONS TO
OVERCOME THE LIMITED MOISTURE AND PRODUCE PRECIP. WILL KEEP POPS
UP NORTH IN THE FORECAST...WITH SCATTERED COVERAGE POSSIBLE.

A TRAILING SECONDARY SHORTWAVE COULD KEEP SOME PRECIP GOING OVER
THE FAR NORTH SATURDAY. TEMPERATURES STATEWIDE WILL BE NOTICEABLY
COOLER...ESPECIALLY UP NORTH WHERE READINGS WILL BE AROUND 5-15
DEGREES BELOW NORMAL FOR EARLY AUGUST. BUILDING HEIGHTS
SUNDAY/MONDAY WILL BRINGS TEMPS BACK UP AND FORCE ANY LINGERING
PRECIP NORTH OF THE STATE.

THE LATEST VERSIONS OF THE ECMWF AND GFS DO DIFFER TOWARDS THE
MIDDLE OF NEXT WEEK. THE GFS BRINGS A PROGRESSIVE AND ENERGETIC
TROUGH THROUGH SRN CANADA/NRN ROCKIES...WHILE THE ECMWF HOLDS THE
TROUGH BACK OFF THE PACIFIC NW/BRITCOL COAST. INCLINED TO THINK IN
EARLY AUGUST THAT HIGHER HEIGHTS WILL PREVAIL OVER THE INTERIOR
WEST...WHICH WOULD KEEP THE TROUGH EITHER BACK NEAR THE COAST LIKE
THE ECMWF SOLUTION...OR WOULD FORCE THE WESTERLY MUCH FURTHER TO
OUR NORTH. IN EITHER CASE WILL KEEP TEMPS SEASONALLY WARM WITH
LITTLE THREAT FOR PRECIP LATE IN THE EXTENDED FORECAST PERIOD.

&&

.AVIATION...INCREASING SOUTHERLY WINDS ARE EXPECTED AT KSLC TODAY.
ANTICIPATE ONLY A 30 PERCENT CHANCE OF A LATE WIND SWITCH TO
NORTHWEST DURING PEAK HEATING HOURS BETWEEN 21-23Z...OTHERWISE
SOUTH WINDS WILL PREVAIL. ADDITIONALLY...A 20 PERCENT CHANCE EXISTS THAT
FAST MOVING THUNDERSTORMS WILL BRING ERRATIC MICROBURST WIND GUSTS
BETWEEN 22-03Z TODAY/TONIGHT.

&&

.FIRE WEATHER...AN UNUSUALLY DEEP STORM SYSTEM FOR THIS TIME OF
YEAR CURRENTLY OFF THE CALIFORNIA COAST WILL MOVE INLAND TONIGHT AND
TRACK ACROSS THE INTERMOUNTAIN WEST THROUGH FRIDAY. WIDESPREAD
SEVERE FIRE WEATHER CONDITIONS ARE FORECAST DURING THIS TIME PERIOD.
PLEASE REFERENCE WARNINGS AND WATCHES FOR DETAILED INFORMATION FOR
YOUR AREA.

SOUTHERLY WINDS WILL BEGIN TO INCREASE ACROSS WESTERN UTAH TODAY.
WHEN COMBINED WITH THE POOR HUMIDITY RECOVERY SEEN
OVERNIGHT...CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED THIS
AFTERNOON. THERE WILL ALSO BE A THREAT OF DRY LIGHTNING THIS
AFTERNOON AND EVENING AS ISOLATED THUNDERSTORMS DEVELOP ACROSS
NORTHERN AND WESTERN UTAH...WITH SCATTERED ACTIVITY ACROSS THE
HIGHER TERRAIN OF SOUTHERN AND CENTRAL UTAH.

POOR MOISTURE RECOVERY IS ANTICIPATED TONIGHT AS WINDS INCREASE OUT
OF THE SOUTH.

VERY GUSTY SOUTHERLY WINDS CAN BE EXPECTED TOMORROW AS THE COLD
FRONT CROSSES NEVADA. DRYING AHEAD OF THIS FEATURE SHOULD LIMIT DRY
THUNDERSTORM ACTIVITY TO THE HIGHER TERRAIN AND ACROSS PORTIONS OF
NORTHERN UTAH NEAR THE NEVADA AND IDAHO STATE LINES. PROLONGED AND
WIDESPREAD SEVERE FIRE CONDITIONS ARE EXPECTED.

WITH THE COLD FRONT MOVING ACROSS NORTHERN UTAH THURSDAY
NIGHT...BETTER HUMIDITY RECOVERY IS ANTICIPATED. HOWEVER...MOISTURE
RECOVERY WILL REMAIN POOR ACROSS MUCH OF SOUTHERN AND CENTRAL UTAH
WITH GUSTY SOUTHERLY WINDS AHEAD OF THE COLD FRONT.

COOLER CONDITIONS ARE EXPECTED FRIDAY AS THE TROUGH REACHES THE
EASTERN GREAT BASIN. SCATTERED ORGANIZED THUNDERSTORMS ARE EXPECTED
ACROSS NORTHERN UTAH. HOWEVER...ACROSS SOUTHERN AND EASTERN
UTAH...DRY AND WINDY CONDITIONS ARE EXPECTED TO CONTINUE.

MOISTURE RECOVERY WILL BECOME A LOT MORE EFFICIENT FRIDAY NIGHT
ACROSS NORTHERN AND CENTRAL UTAH...BUT LAG ACROSS SOUTHERN UTAH.
WINDS WILL NOT BE AS GUSTY AS THURSDAY NIGHT...THOUGH LOCALLY GUSTY
SOUTHWEST WINDS WILL BE POSSIBLE ACROSS SOUTHERN UTAH.

RELATIVELY COOL CONDITIONS WITH A DRYING TREND IS EXPECTED SATURDAY.
ISOLATED THUNDERSTORMS WILL STILL BE POSSIBLE ACROSS NORTHERN UTAH
DURING THE AFTERNOON AND EVENING. WEST NORTHWEST WINDS WILL BEGIN TO
DIMINISH AS HIGH PRESSURE BUILDS INTO THE REGION.

INCREASING MOISTURE AHEAD OF A DEVELOPING COLD FRONT OVER CENTRAL
NEVADA WILL PRODUCE ISOLATED TO WIDELY SCATTERED THUNDERSTORMS
ACROSS THE STATE TODAY. DRY LOW LEVELS COMBINED WITH INCREASING
SOUTHERLY WINDS BOTH AT THE SURFACE AND ALOFT WILL BRING A THREAT
OF MICROBURST WINDS AND DRY LIGHTNING WITH THESE STORMS THIS
AFTERNOON AND EVENING. ADDITIONALLY...THE INCREASING SURFACE WINDS
COMBINED WITH LOW HUMIDITY VALUES WILL INCREASE CRITICAL FIRE
WEATHER CONDITIONS ACROSS THE WESTERN THIRD OF THE STATE.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

SOUTHERLY WINDS WILL CONTINUE TO INCREASE THROUGHOUT THE REGION
THROUGH THURSDAY EVENING. CRITICAL FIRE WEATHER CONCERNS WILL
SPREAD EASTWARD ENCOMPASSING MUCH OF THE STATE DURING THE DAY.

THUNDERSTORMS TO NORTHERN UTAH. THE FRONT WILL BE REPLACED BY
SIGNIFICANTLY COOLER TEMPERATURES FRIDAY AND SATURDAY ACROSS
NORTHERN AND CENTRAL UTAH. SOUTHERN UTAH WILL COOL SLIGHTLY...
THOUGH READING WILL STILL BE CLOSE TO SEASONAL NORMS.

HIGH PRESSURE ALOFT WILL REBOUND ACROSS THE AREA BEGINNING
