AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
840 PM MDT MON JUN 12 2006

.SYNOPSIS...AN UPPER LEVEL RIDGE OVER THE ROCKIES WILL MOVE
SLOWLY TO THE EAST AS AN UPPER LEVEL DISTURBANCE MOVES INTO THE
GREAT BASIN. THIS SYSTEM WILL PUSH A WEAKENING COLD FRONT INTO THE
REGION TUESDAY NIGHT AND SCATTERED THUNDERSTORMS. BEHIND THIS SYSTEM
MUCH OF UTAH WILL HAVE A COOLING TREND ON WEDNESDAY AND THURSDAY.

&&

.DISCUSSION...BACKSIDE OF UPPER RIDGE OVER THE REGION TODAY. VERY
DRY AIR MASS RESULTED IN SINGLE DIGIT HUMIDITIES REGION WIDE. 14C
700 MB TEMPS REACHED THE GSL WHICH WITH DRY ADIABATIC MIXING BROUGHT
TEMPS INTO THE LOW TO MID 90S FOR NORTHERN LOWER VALLEYS. THE
SQUEEZE BETWEEN THE UPPER TROUGH ON THE WEST COAST AND THE RIDGE TO
THE EAST WILL INCREASE MID LEVEL FLOW TONIGHT. WITH DRY AIR MASS
MOUNTAIN VALLEYS AND DESERTS WILL COOL SIGNIFICANTLY SIMILAR TO LAST
NIGHT...EXCEPT WESTERN VALLEYS AND DESERTS WILL HAVE MORE
DIFFICULTLY DECOUPLING WITH INCREASE WIND FLOW. 35 KNOTS OF WIND
FLOW AT 700 MB IS OVER WESTERN UTAH EARLY TUESDAY. THIS WILL LEAD TO
WIND ADVISORY TYPE WINDS FOR WESTERN VALLEYS AND DESERTS ON TUESDAY.

GFS AND NAM BRING A SURGE OF HIGHER PRECIPITABLE WATER OVER WESTERN
AREAS TOWARD 6 PM TUESDAY. VALUES GO FROM .2 TO .3 INCHES TO NEAR
.75 INCHES QUICKLY IN MODERATE FLOW ALOFT. MOISTURE ADVECTION
RESULTS IN DESTABILIZATION WITHIN STEEP LAPSE RATES IN PLACE.
INITIALLY THE 450-500 MB STABLE LAYER CAPS CONVECTION CHANCES BUT
MODEL SOUNDINGS BREAK THIS LAYER EARLY TUESDAY EVENING AS SHORT WAVE
TROUGH EJECTS ACROSS NORTHEAST NEVADA THROUGH NORTHERN UTAH WITH
SYNOPTIC LIFT AND COOLING ALOFT DESTABILIZATION. MAIN WAVE QUICKLY
LIFTS TO THE NORTH BY 12Z WEDNESDAY WHICH BRINGS WARM AIR ADVECTION
ALOFT AND SHUNTS MOISTURE INTO EASTERN UTAH. THUS GIVEN DYNAMICS AND
MOISTURE INTERACTION EVENING CONVECTION OVER WESTERN UTAH WILL BE
QUICK MOVING AND HAVE DRY MICROBURSTS POTENTIAL WITH SOME RAINFALL.
NOCTURNAL ACTIVITY WILL CONTINUE INTO NORTHEAST UTAH TUESDAY NIGHT
AND PARTS OF EASTERN UTAH AS THE SHORT WAVE TROUGH LIFTS NORTHEAST.
SHALLOW LOW LEVEL COLD FRONT DROPS THROUGH THE GSL WEDNESDAY
MORNING. THIS TIMING CLOSE TO WHAT THE NAM HAS BEEN SHOWING FOR
SEVERAL DAYS.

SECONDARY WAVE PUSHES THROUGH WEDNESDAY EVENING WHICH WILL PUSH THE
COLD FRONT INTO SOUTH CENTRAL UTAH WEDNESDAY NIGHT. SOME CONVECTION
ALONG THE 700 MB BAROCLINIC ZONE IN NORTHERN UTAH POSSIBLE. NAM AND
GFS BRING THE UPPER TROUGH AXIS THROUGH UTAH ON THURSDAY WITH
SIGNIFICANT COOLING IN THE NORTH. CURRENT GRIDS MAY BE MUCH TOO WARM
WITH NORTHERN VALLEYS POSSIBLY HOLDING IN THE 70S. SCATTERED SHOWERS
AND THUNDERSTORMS POSSIBLE THURSDAY FOR NORTHERN 2/3 OF UTAH AND
MOST FOCUSED ALONG BAROCLINIC ZONE IN CENTRAL UTAH. COOLING FORECAST
TO AFFECT SOUTHWEST UTAH AS WELL. UPPER TROUGH EXITS BY FRIDAY AND
AIR MASS MODIFIES WITH DRY WEATHER. FLAT UPPER RIDGE PROGGED FOR THE
WEEKEND WHICH WOULD BRING SIGNIFICANT WARMING TREND ESPECIALLY FOR
NORTHERN AREAS. A NOTED DIFFERENCE ON TODAYS ECMWF WHICH LEFT ENERGY
OVER THE SOUTHWEST FRIDAY MORNING INSTEAD OF PUSHING A PROGRESSIVE
TROUGH THROUGH THE GREAT BASIN LIKE THE GFS AND UKMET. LEAN TO THE
GFS WITH RECENT PATTERN.

&&

.AVIATION...LAKE BREEZE MOVED IN ABOUT 630 PM. EXCEPT THIS TO LEAVE
BY 04Z WITH INCREASING DOWNSLOPE SOUTHERLY FLOW OVERNIGHT WITH
THERMAL TROUGH IN THE NORTHWEST DESERTS EXTENDING INTO NORTHEAST
NEVADA. LOOK FOR WINDY CONDITIONS ON TUESDAY. LITTLE CHANCE FOR LAKE
BREEZE TUESDAY AFTERNOON BUT CONVECTIVE OUTFLOW FROM HIGH BASED
THUNDERSTORMS MOVING THROUGH THE NORTHWEST DESERTS WILL BE AN ISSUE.

&&

.FIRE WEATHER...A VERY DRY AIRMASS WILL REMAIN ACROSS THE AREA
THROUGH TUESDAY. THIS COMBINED WITH GUSTY SOUTH WINDS WILL RESULT IN
CRITICAL FIRE WEATHER CONDITIONS UNTIL JUST AFTER SUNSET IN ALL
AREAS EXCEPT THE WASATCH FRONT AND NORTHERN UTAH MOUNTAINS.
CONDITIONS WILL MODERATE SLIGHTLY OVERNIGHT...BUT EXPECT POOR
OVERNIGHT RECOVERIES ON MIDSLOPE LOCATIONS AND AREAS EXPOSED TO
WIND. RED FLAG CONDITIONS WILL RETURN TO MUCH OF THE
DISTRICT...INCLUDING THE SOUTHERN WASATCH FRONT...TUESDAY AFTERNOON
AND EVENING AS WINDS INCREASE AGAIN. THERE WILL BE AN ADDED THREAT
OF DRY THUNDERSTORMS LATE TUESDAY AS WELL. A COLD FRONT WILL MOVE
THROUGH NORTHERN UTAH WEDNESDAY MORNING AND INTO CENTRAL UTAH BY
