ANOTHER WEAK UPPER LOW WILL CROSS THE AREA SATURDAY AFTERNOON. HIGH PRESSURE WILL BUILD INTO THE STATE ON SUNDAY. && .DISCUSSION...UPPER LOW CONTINUES TO TRACK NORTHEAST INTO WYOMING. THE ASSOCIATED VORTICITY LOBE WITH THIS FEATURE CONTINUES TO AFFECT SOUTHWEST WYOMING...THE NORTHERN WASATCH MOUNTAINS AND THE UINTAH MOUNTAINS. THIS TROUGH WILL SHIFT EAST TONIGHT AS A WEAK SHORT WAVE RIDGE BUILDS IN FROM THE WEST. SECONDARY WEAKER SHORT WAVE THAT WAS OVER NORTHEAST NEVADA THIS MORNING IS NOW BEGINNING TO MERGE WITH TAIL END OF EJECTING LOW OVER NORTHWEST UTAH AND SOUTHEAST IDAHO. CONVECTION HAS COMMENCED AND WILL MOVE SLOWLY ACROSS MAINLY NORTHERN UTAH THIS AFTERNOON AND EVENING. OVER THE SOUTHWESTERN PORTION OF THE STATE SKIES WERE MOSTLY CLEAR THIS MORNING AND AFTERNOON HEATING IS SPAWNING CONVECTION OVER THE SOUTHERN MOUNTAINS. PRECIPITABLE WATER VALUES OF AROUND 3/4 OF AN INCH ARE THE NORM STATEWIDE. THIS IS MORE THAN SUFFICIENT FOR ISOLATED THUNDERSTORMS TO REMAIN OVER THE SOUTHERN MOUNTAINS THROUGH THIS EVENING. AS MENTIONED THIS MORNING...ON SATELLITE WATER VAPOR IMAGE A WEAK FEATURE CONTINUES TO TRACK EASTWARD ACROSS SOUTHERN NEVADA. THIS FEATURE COULD ENHANCE CONVECTION ACROSS THE SOUTH LATER THIS AFTERNOON AND HAVE RAISED POPS A BIT OVER THE SOUTHWEST MAINLY OVER THE MOUNTAINS. SHORTWAVE RIDGE AXIS WILL BE OVER WESTERN UTAH BY NOON TOMORROW AS DEVELOPING UPSTREAM TROUGH PUSHES INTO THE PACIFIC NORTHWEST. LEADING CLOUD EDGE OF THIS TROUGH IS JUST NOW PUSHING ONTO THE PACIFIC NORTHWEST COAST.

RIDGE WILL BEGIN TO DOMINATE ON SUNDAY PUSHING THE REMAINDER OF MOISTURE AND CONVECTION TO THE EASTER HALF OF THE STATE. RIDGE WILL THEN STRENGTHEN OVER THE WESTERN STATES AND PUT UTAH UNDER A MUCH DRIER NORTHWEST FLOW FOR MONDAY AND TUESDAY. THE RIDGE WILL THEN STRENGTHEN OVER THE EASTERN PACIFIC AND ALLOW A WEAK TROUGH TO DRIFT INTO THE NORTHERN ROCKIES WEDNESDAY AND DEVELOP INTO A DECENT LOOKING LOW BY THURSDAY. THIS SYSTEM WILL PUSH A WEAK COOL BOUNDARY INTO NORTHERN UTAH THURSDAY WHICH SHOULD LOWER TEMPERATURES A FEW DEGREES OVER THE NORTHERN HALF OF THE STATE. MUCH STRONGER COLD BOUNDARY PUSHES INTO THE STATE FRIDAY AND WILL LOWER TEMPERATURES A FEW DEGREES MORE STATEWIDE. NOT A LOT OF MOISTURE WITH THURSDAY FRONT BUT A GOOD SLUG OF MOISTURE EXPECTED FRIDAY FOR MAINLY THE NORTHERN TWO-THIRDS OF THE STATE FOR AN INCREASING CHANCE FOR PRECIPITATION. && .AVIATION...CONVECTION HAS STARTED TO FIRE UP OVER NORTHERN UTAH THIS AFTERNOON AND THESE WILL OCCASIONALLY AFFECT APPROACH ROUTES TO SLC THROUGH THIS EVENING.
