AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SALT LAKE CITY UT 250 PM MDT MON JUL 10 2006 .SYNOPSIS...WEAK DISTURBANCES WILL CONTINUE TO MOVE ACROSS THE REGION TODAY THROUGH TUESDAY. THE AIRMASS WILL SLOWLY DRY AND WARM UP BY MID WEEK. && .DISCUSSION...ANOTHER ACTIVE CONVECTION DAY OVER THE FORECAST AREA. WELL DEFINED SHORT WAVE TROUGH EXTENDS FROM WESTERN WYOMING AND BACK TO THE SOUTHWEST ACROSS SLC THIS HOUR AND INTO SOUTHEAST NEVADA. SCATTERED THUNDERSTORMS HAVE BEEN DEVELOPING PAST COUPLE HOURS ALONG THE IDAHO BORDER AND ISOLATED STRONG CELLS IN SOUTHWEST WYOMING AND SOUTHWEST OF SLC OVER THE STANSBURY AND TINTIC MOUNTAINS EAST ACROSS THE WASATCH PLATEAU AND SOUTHERN UINTAS. STRONGEST CELL MOVING SOUTHEAST OF DUCHESNE. THIS WILL BE THE SEVERE WEATHER THREAT NEXT FEW HOURS AND SOUTH INTO CASTLE COUNTRY AND SAN RAFAEL SWELL AS THE LEADING UPPER TROUGH AXIS CROSSES THIS AFTERNOON. ACROSS CENTRAL AND SOUTHERN UTAH...EARLIER DECK OF MID LEVEL CLOUDS AND LIGHT SHOWERS HAS DEVELOPED ORGANIZED STRONGER CONVECTION ON THE NORTH AND WEST SIDE HAVE BEEN PRODUCING HEAVY RAIN AND ARE VERY SLOW MOVING. STRONG WEST FLOW IN THE NORTH HAS BEEN MOVING CELLS A LITTLE FASTER EAST. ALL THIS ACTIVITY GETTING A KICK FROM SHORT WAVE LIFTING INTO FAR NORTHWEST IDAHO AND MONTANA WITH THE TAIL OF THIS TROUGH EXTENDING SOUTHWEST ACROSS SOUTHERN IDAHO AND NORTHERN NEVADA. SUBSIDENCE WILL TAKE OVER AROUND THE GSL BASIN NEXT COUPLE HOURS WITH FLOW VEERING TO NORTHWEST ALOFT...BUT THE TAIL OF THE NEXT WAVE WILL DROP ACROSS NORTHERN UTAH LATE THIS EVENING WHICH BACKS THE FLOW AGAIN...KEEPING SCATTERED CONVECTION OVER NORTHERN UTAH AFTER PEAK HEATING. CONVECTION ALONG THE IDAHO BORDER HILLS IS QUITE ORGANIZED WITH THIS LINEAR ORIENTED SYNOPTIC LIFT. IN SOUTHWEST UTAH 18Z NAM-WRF STILL DEPICTS A DEFORMATION AXIS AND WEAK MID LEVEL CIRCULATION TO LINGER OVERNIGHT. EXPECT THE THERMAL SURFACE TROUGH OVER THE WEST DESERTS INTO SOUTHWEST UTAH TO BECOME INCREASINGLY ACTIVE THIS AFTERNOON AND FOR ORGANIZED CONVECTION TO LAST INTO THE EVENING WITH MARGINAL SYNOPTIC SUPPORT IN THE OVERNIGHT HOURS. 18Z NAM-WRF AND 12Z GFS KEEP A WEAK MID LEVEL CONFLUENT AREA OVER SOUTH CENTRAL UTAH ON TUESDAY WITH A WEAK CIRCULATION MOVING EAST. THIS WILL BE THE FOCUS OF CONVECTION IN THE SOUTH AND CENTRAL AREA. MEANWHILE THE WEST SIDE OF THIS DISTURBANCE WILL BOW NORTH INTO NORTHWEST UTAH AND SPREAD HIGH PRECIPITABLE WATER AXIS BACK INTO THE NORTHWEST. SCATTERED TO NUMEROUS CONVECTION WILL OCCUR IN THE NORTHWEST WITH A GOOD CHANCE CELLS FROM THE DESERTS AND OQUIRRHS WILL SPREAD INTO THE WASATCH FRONT/GSL. AIR MASS WARMS SLIGHTLY BUT AFTERNOON CLOUD COVER AND ANVIL MAY HOLD TEMPS DOWN IN PARTS OF THE REGION. CONVECTION WILL CONTINUE INTO THE EVENING...WITH STILL A THREAT FOR LOCALLY HEAVY RAIN ON TUESDAY WITH GENERALLY 10 KNOTS OF STEERING WESTERLY FLOW OVER THE MIDDLE OF UTAH. NVA SUBSIDENCE SPREADS IN FROM THE WEST LATER TUESDAY NIGHT. THIS IS FORECAST TO BRING THE DRYING OVER MOST OF NORTHERN UTAH ON WEDNESDAY WHILE ENOUGH MOISTURE REMAINS IN CENTRAL AND SOUTHERN UTAH FOR AT LEAST TERRAIN DRIVEN CONVECTION WEDNESDAY AFTERNOON. AIR MASS WARMS ABOUT ANOTHER DEGREE CELSIUS. MEAN FLOW STARTS TO BACK ON THURSDAY PER MODELS...WITH THE NAM-WRF FASTER THAN THE LATEST GFS RUNS. THIS BRINGS THE 17C ISOTHERM AT 700 MB INTO NORTHERN UTAH AND WILL ALLOW MARGINAL BUT SUFFICIENT MOISTURE TO PERSIST OVER SOUTHERN UTAH AND POSSIBLE INCREASE INTO FRIDAY...SO KEPT PRECIP CHANCES IN GRIDS OVER CENTRAL AND SOUTHERN AREAS. 594 DAM HEIGHTS STILL PROGGED TO SET UP OVER THE GREAT BASIN AND WEAK FLOW FOR THE WEEKEND WHICH WILL LEAD TO DIURNAL CONVECTION IN STEEP LAPSE RATES AND SUFFICIENT MOISTURE AND HOT AFTERNOON TEMPERATURES. POTENTIAL FOR 100F AT SLC. MORE SIGNIFICANT MONSOON SURGE LIKELY TO BE LET INTO UTAH GIVEN POSITION OF THE UPPER HIGH...HOWEVER IF IT BUILDS TO FAR WEST THIS MAY DELAY THE DEEPER MOISTURE BUT SUSTAIN VERY HOT TEMPERATURES INTO MONDAY. && .AVIATION...STORMS MOVING ALONG THE SOUTHERN PART OF THE VALLEY COULD SWITCH WINDS BRIEFLY SOUTH FOR UP TO TWO HOURS...BUT NOT ENOUGH RAIN-COOLED AIR IS PRESENT WITH THESE STORMS TO KEEP THE FLOW OUT OF THE SOUTH. THERE IS A 20 PERCENT CHANCE THAT THE KSLC AREA MAY SEE A THUNDERSTORM THAT ARRIVES OFF OF THE OQUIRRH MOUNTAINS THROUGH 22Z. ANY OUTFLOW WINDS SHOULD BE OUT OF THE SOUTHWEST TO WEST. VFR CONDITION SHOULD PERSIST THOUGH. && .FIRE WEATHER...MOISTURE REMAINS OVER SOUTHERN AND EASTERN UTAH FOR A CHANCE OF WETTING RAINS THROUGH THIS EVENING. DRIER AIRMASS OVER THE NORTH SHOWING AN INCREASE IN MOISTURE WITH SHOWERS AND THUNDERSTORMS NOW DEVELOPING ALONG THE UTAH-IDAHO BORDER AND OVER THE MOUNTAIN RANGES OF NORTHERN UTAH. AS A RESULT...COULD SEE WETTING RAINS OVER THE NORTHWEST THROUGH THIS EVENING AS WELL. DRYING TREND FOR TOMORROW WILL BE A BIT OF A MISNOMER AS SHORT WAVES WILL CONTINUE TO PRODUCE AFTERNOON AND EVENING CONVECTION ACROSS MUCH OF THE STATE. WINDS ARE STILL EXPECTED TO INCREASE OUT OF THE SOUTHWEST AND HUMIDITIES WILL BE LOW...HOWEVER CRITICAL FIRE WEATHER CONDITIONS WILL BE BORDERLINE AT BEST FOR WEDNESDAY. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...NONE. WY...NONE. && TARDY AVIATION...HALL FIRE WEATHER...YOUNG
