AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
314 PM MDT MON JUN 24 2013
.SYNOPSIS...LAST WEATHER DISTURBANCE WILL MOVE SOUTHWEST TO
NORTHEAST ACROSS THE STATE THIS EVENING. STRONG HIGH PRESSURE
WILL BUILD OVER THE REGION MIDWEEK...GENERATING HOT TEMPERATURES
STATEWIDE BY THE END OF THE WEEK.
&&
.DISCUSSION...LAST SHORT WAVE OVER NEVADA AT THIS TIME POISED TO
SWING THROUGH UTAH THIS EVENING. A WEAK COOL BOUNDARY WILL
ACCOMPANY THIS WAVE AND BRING THE BEST CHANCE FOR PRECIPITATION
ACROSS NORTHERN UTAH FOR THE NEXT SEVERAL DAYS. PRECIPITABLE
WATER VALUES OF HALF AN INCH PER 12Z SOUNDING PROGGED TO BUMP UP
TO 3/4 OF AN INCH THIS EVENING PER BUFR SOUNDINGS. BOUNDARY LAYER
STILL QUITE DRY AND IT WILL REMAIN DIFFICULT TO GET MEASURABLE
PRECIPITATION AT ANY GIVEN LOCATION. SOUTHERLY FLOW HAS DEVELOPED
OVER THE WESTERN DESERTS AND BORDERLINE ADVISORY LEVELS HAVE BEEN
REACHED AT TIMES BUT DO NOT ANTICIPATE THEM LASTING FOR 3 HOURS OR
MORE...SO NO ADVISORY HAS BEEN ISSUED. BREEZY TO WINDY CONDITIONS
AND LOW HUMIDITIES WILL ALLOW RED FLAG CONDITIONS TO OCCUR...SEE
FIRE WEATHER DISCUSSION BELOW. HIGH BASED CONVECTION HAS DEVELOPED
OVER NORTHEAST NEVADA AND IS NOW SPREADING INTO NORTHWEST UTAH AS
PREVIOUSLY DISCUSSED. STRONG MICROBURST WINDS AND DRY LIGHTNING
BUT LITTLE IF ANY RAINFALL IS MOST LIKELY SCENARIO.
HIGH PRESSURE ALOFT IS THEN FORECAST TO AMPLIFY ACROSS THE GREAT
BASIN FOR THE MIDDLE OF THE WEEK AND BEYOND. THIS WILL BRING A
MARKED WARMING TREND TO THE STATE WITH HOTTEST TEMPERATURES OF THE
YEAR TO BE REALIZED. TEMPERATURES ALONG THE WASATCH FRONT WILL BE
THREATENING THE CENTURY MARK BY THURSDAY...WITH MAX TEMPS IN DIXIE
PUSHING 110 BY THE WEEKEND. DEPENDING ON HOW THIS RIDGE BECOMES
ORIENTED...MAY SEE ENOUGH MOISTURE...AND THE MODELS HINT AT
THIS...WORK INTO THE STATE TO BRING ISOLATED CONVECTION TO
MAINLY THE HIGHER TERRAIN BY THE WEEKEND.
&&
.AVIATION...GUSTY SOUTH TO SOUTHWEST WINDS WILL CONTINUE AT THE SLC
TERMINAL INTO THE EVENING. A WIND SHIFT TO THE NORTHWEST ASSOCIATED
WITH A RELATIVELY WEAK COLD FRONT IS EXPECTED BETWEEN 01-03Z.
AN AREA OF HIGH BASED SHOWERS AND THUNDERSTORMS IS CURRENTLY
CROSSING THE WEST DESERT AND WILL BE MOVING ACROSS THE SALT LAKE
AREA AROUND 21-23Z. THE MAIN THREAT WITH THIS AREA OF PRECIPITATION
WILL BE GUSTY AND ERRATIC WINDS. ANOTHER BAND OF HIGH BASED SHOWERS
AND THUNDERSTORMS IS EXPECTED BETWEEN 00-03Z.
&&
.FIRE WEATHER...STRONG AND GUSTY SOUTH WINDS WILL PERSIST INTO THE
EVENING HOURS AHEAD OF AN APPROACHING WEATHER DISTURBANCE.
HOWEVER...THESE WINDS WINDS WILL TURN MORE WESTERLY ACROSS NORTHERN
UTAH THIS EVENING BEHIND A SHALLOW COLD FRONT. WINDS SHOULD DECREASE
DURING THE OVERNIGHT HOURS AS THE DISTURBANCE LIFTS NORTHEAST OUT OF
THE AREA. RELATIVE HUMIDITIES REMAIN QUITE LOW AHEAD OF THE COLD
FRONT...AND THE COMBINATION OF LOW HUMIDITIES AND STRONG WINDS WILL
CONTINUE TO CREATE WIDESPREAD HAZARDOUS FIRE WEATHER CONDITIONS
THROUGH THIS EVENING FOR MOST AREAS WHERE FUELS ARE CRITICALLY DRY.
A MIDLEVEL MOISTURE PLUME SPREADING INTO THE AREA HAS BROUGHT
AMPLE CLOUD COVER TO THE REGION. IN ADDITION...ISOLATED TO WIDELY
SCATTERED MOSTLY DRY THUNDERSTORMS ARE EXPECTED THROUGH
TONIGHT...MOSTLY ACROSS THE NORTH. THESE STORMS WILL LIKELY
PRODUCE GUSTY AND ERRATIC OUTFLOW WINDS BUT VERY LITTLE RAINFALL.
HUMIDITIES WILL INCREASE BEHIND THE COLD FRONT AND AFTERNOON
RELATIVE HUMIDITY VALUES WILL BE HIGHER TOMORROW ACROSS THE NORTH
AND WEST THAN IT HAS BEEN IN QUITE A FEW DAYS. HOWEVER...DRY
CONDITIONS WILL PERSIST ACROSS THE SOUTHEAST AND THERE MAY BE ENOUGH
WINDS TO CREATE ISOLATED/MARGINAL CRITICAL FIRE WEATHER CONDITIONS
ACROSS THE FAR SOUTH TOMORROW AFTERNOON. OTHERWISE...QUIET WEATHER
WILL RETURN AS STRONG HIGH PRESSURE BUILDS INTO THE AREA FOR THE
SECOND HALF OF THE WEEK AND THROUGH THE WEEKEND. EXPECT DRY AND VERY
HOT CONDITIONS WITH GENERALLY LIGHT WINDS DURING THIS TIME.
