NATIONAL WEATHER SERVICE SALT LAKE CITY UT
422 PM MDT MON AUG 25 2014

.SYNOPSIS...THE NEXT STORM SYSTEM WILL MOVE SLOWLY ACROSS THE
REGION TONIGHT THROUGH WEDNESDAY. HIGH PRESSURE WILL RETURN TO
THE AREA FOR THE LATTER PART OF THE WEEK.



&&

.DISCUSSION...A PACIFIC TROUGH IS DIGGING INTO THE GREAT BASIN
THIS AFTERNOON...AND HAS ALREADY BEGUN IMPACTING UTAH AND
SOUTHWEST WYOMING. SCATTERED SHOWERS AND THUNDERSTORMS HAVE FORMED
ACROSS THE NORTHERN TWO THIRDS OF THE CWA...WITH SEVERAL OF THESE
STORMS PRODUCING HEAVY RAIN AND DECENT SIZED HAIL. REPORTED HAIL
SO FAR HAS BEEN SUB-SEVERE...BUT A COUPLE OF STORMS WITHOUT
REPORTS HAVE APPEARED TO BE SEVERE ON RADAR IMAGERY.

THE TROUGH WILL MOVE ACROSS THE CWA THROUGH TUESDAY AND
WEDNESDAY...AND IS EXPECTED TO PRODUCE WIDESPREAD CLOUD COVER AND
PRECIPITATION. THE HEAVIEST RAINFALL WILL LIKELY BE ALONG THE
UTAH/ARIZONA BORDER ON TUESDAY AFTERNOON...AS DEEP MOISTURE MOVES
OVER THE AREA FROM THE SOUTH. THE TROUGH LOOKS TO EXIT THE REGION
LATE WEDNESDAY...WITH SHORTWAVE RIDGING BUILDING OVER THE AREA
BEGINNING THURSDAY MORNING.

THE AIRMASS UNDER THE RIDGE IS EXPECTED TO BE DRIEST AND WARMEST
OVER THE AREA IN MORE THAN A WEEK...AND TEMPERATURES WILL LIKELY
RETURN TO NEAR OR SLIGHTLY ABOVE NORMAL FOR THE END OF AUGUST. THE
PATTERN REMAINS FAIRLY PROGRESSIVE HOWEVER...WITH THE NEXT BROAD
TROUGH MOVING THROUGH THE PACIFIC NORTHWEST AND GREAT PLAINS
SATURDAY THROUGH MONDAY. THE SOUTHERN END OF THIS TROUGH IS
PROGGED TO CLIP THE FORECAST AREA BEGINNING LATE SATURDAY AND
CONTINUING THROUGH THE BEGINNING OF NEXT WEEK...COOLING
TEMPERATURES A BIT AND INCREASING THE CHANCE OF PRECIPITATION
ACROSS THE NORTHERN HALF OF THE AREA.

&&

.AVIATION...NORTH WINDS WITH PREVAILING VFR CONDITIONS CAN BE
EXPECTED THROUGH 04Z AT THE KSLC TERMINAL...WITH A WIND SHIFT BACK
TO THE SOUTH BY 06Z. THERE IS A 30 PERCENT CHANCE OF SHOWERS AND
THUNDERSTORMS CAPABLE OF PRODUCING MVFR VISIBILITY WITHIN HEAVY RAIN
THROUGH THE EVENING.

&&

.FIRE WEATHER...ANOTHER EARLY FALL LIKE STORM SYSTEM WILL MOVE ACROSS
THE REGION TUESDAY THROUGH WEDNESDAY BRINGING SHOWERS AND
THUNDERSTORMS. WETTING RAINS WILL OCCUR OVER MAINLY SOUTHERN AND
CENTRAL UTAH BUT MANY AREAS OF NORTHERN UTAH WILL ALSO RECEIVE
OVER 0.10 OF AN INCH AS WELL. THIS SYSTEM WILL EXIT THE REGION
THURSDAY WITH A CHANCE OF SHOWERS AND THUNDERSTORMS STILL OVER THE
EASTERN ZONES BUT THEN ALL AREAS DRY FOR FRIDAY AND SATURDAY.
