AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1030 AM MDT TUE AUG 29 2006

.SYNOPSIS...SOUTHERLY FLOW INCREASES AS A PACIFIC TROUGH MOVES
SLOWLY EAST ACROSS THE NORTHERN ROCKIES AND NORTHERN GREAT BASIN
WEDNESDAY THROUGH EARLY FRIDAY. HIGH PRESSURE WILL RETURN FOR THE
HOLIDAY WEEKEND.

&&

.DISCUSSION...PROGRESSIVE PATTERN BUT WITH WITH AMPLIFIED SYSTEMS
ACROSS THE WESTERN US. A COOL PACIFIC LOW IS MOVING ONSHORE THE
PACNW THIS MORNING AS THE UPPER RIDGE OVER THE GREAT BASIN SLIDES
EAST. SOUTHWEST FLOW INCREASING MAY PUSH SOME AREAS TO THE CRITICAL
FIRE WEATHER THRESHOLD FOR WIND/RH. SEE THE FIRE WEATHER DISCUSSION
BELOW. OTHERWISE...A WARM BREEZY DAY STATEWIDE. THREAT OF CONVECTION
IS SMALL...BUT A FEW THUNDERSTORMS MAY POP OVER THE CENTRAL
MOUNTAINS AND THE UINTAS THIS AFTERNOON AS A WEAK SHORTWAVE CAUGHT
IN THE SOUTHWEST FLOW MOVES INTO SOUTHWEST WYOMING.

THE NEXT BIG NEWS STORY IS A PUSH OF COLD AIR COMING FOR MIDWEEK.
THE GFS/UKMET/ECMWF IS FAIRLY GOOD AGREEMENT WITH MOVING THE LARGE
UPPER LOW ACROSS CENTRAL IDAHO ON THURSDAY...THEN CLOSING IT OFF
OVER THE HIGH PLAINS OF NE/WY ON FRIDAY. SOME COOLING EXPECTED
WEDNESDAY AFTERNOON AS A SHOT OF COOLER AIR MOVES INTO NORTHERN
UTAH. THE MAIN POUCH COMES THURSDAY AFTERNOON. THE OUTLYING MODEL AT
THIS POINT IS THE WRF...WHICH NEVER REALLY DELIVERS THE COOLEST AIR
THROUGH THE END OF ITS RUN 00Z SAT. AT THIS POINT THE WRF IS BEING
DISCOUNTED AS IT IS NOT PICKING UP ON THE STRONG JET MAX ON THE BACK
SIDE OF THE PACIFIC SYSTEM. ONCE THIS JET IS WITHIN THE DATA FIELD
OF THE WRF THINGS SHOULD GET BETTER WITH ITS FORECAST.

SO...CONTINUING WITH THE IDEA OF A DUAL SHOT OF COOLING WED-THURS.
THE GENERAL MODEL CONSENSUS IS THAT H7 TEMPS AT SLC DROP TO 6-8C BY
FRIDAY...THEN REBOUNDS SLOWLY THROUGH THE WEEKEND. THE BEST CHANCES
FOR PRECIP IS AHEAD OF THE FRONT ACROSS SOUTHEASTERN UTAH ON
THURSDAY...HOWEVER THERE REALLY IS NOT A SIGNIFICANT TAP OF TROPICAL
MOISTURE. THE DEEP MOISTURE IS SUPPRESSED PRETTY FAR SOUTH IN AZ.

THE CURRENT TRENDS ARE FOR A MORE BLOCKED UP PATTERN...ALTHOUGH NOT
A FULL OMEGA BLOCK SETTING EARLY NEXT WEEK. DIRTY WEAK RIDGING
EXPECTED OVER THE GREAT BASIN.

&&

.AVIATION...LAKE BREEZE NOT EXPECTED TO DEVELOP TODAY WITH STRONG
SOUTHERLY FLOW. HOWEVER...THERE IS A 30 PERCENT CHANCE THAT A PERIOD
OF LIGHT AND VARIABLE WINDS WILL OCCUR IN THE 20-00Z TIMEFRAME.

&&

.FIRE WEATHER...SOUTH WINDS WILL INCREASE THIS AFTERNOON ACROSS
WESTERN UTAH AHEAD OF APPROACHING DRY COLD FRONT. RED FLAG WARNING
REMAINS IN EFFECT FOR ZONE 420...HOWEVER AM SOMEWHAT CONCERNED
CRITICAL FIRE WEATHER THRESHOLDS MAY BE MET IN ZONE 434 AS WELL...AS
MAV/MET GUIDANCE FOR KMLF SUGGESTS WIND GUSTS WILL APPROACH 30 MPH
THIS AFTERNOON. THIS FRONT SHOULD REACH NORTHWEST UT LATE
TONIGHT/EARLY WEDNESDAY MORNING BEFORE STALLING ACROSS CENTRAL UT
WEDNESDAY AFTERNOON. FIRE WEATHER WATCH REMAINS IN EFFECT FOR GUSTY
WINDS AND LOW RH ACROSS AREAS ALONG AND AHEAD OF THIS FRONT
WEDNESDAY. WILL CONSIDER INCLUDING ZONE 420 AS WELL...AS MODELS
SUGGEST RH VALUES TO FALL BELOW 15 PERCENT DURING THE AFTERNOON WITH
GUSTY NORTHWEST WINDS.
