NWS Salt Lake City, UT wrote its last area forecast discussion before the first event at Jul 26, 3:00 PM MST, 1 hour 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SALT LAKE CITY UT 400 PM MDT WED JUL 26 2006 .SYNOPSIS...A RIDGE OF HIGH PRESSURE WILL STRENGTHEN WEST OF THE AREA CREATING A DRIER NORTHWEST FLOW. MOISTURE WILL INCREASE OVER THE WEEKEND AS THE RIDGE SLIDES EAST OF THE AREA BRINGING A SOUTHWEST FLOW ALOFT. && .DISCUSSION...LINE OF CONVECTION WORKING ITS WAY SOUTHEAST ACROSS NORTHWEST UTAH THIS AFTERNOON. CURRENT SPEED WILL BRING IT ACROSS THE SLC AREA BETWEEN 600 AND 700 PM THIS EVENING. THIS BROKEN LINE IS ASSOCIATED WITH THE ENTRANCE REGION OF A 60 KT 300 MB JET THAT WILL MOVE SOUTHEAST INTO EAST CENTRAL UTAH BY MIDNIGHT. BECAUSE THIS LINE IS BROKEN HAVE NOT GONE LIKELY WITH POPS BUT WE WILL SEE SCATTERED SHOWERS AND THUNDERSTORMS ALL ALONG THE WASATCH FRONT AND GREAT SALT LAKE DESERT. THE AFTERNOON HEATING IS HELPING GENERATE THESE STORMS BUT AS THE SUN SETS THIS SUPPORT WILL VANISH AND THE STORMS WILL SLOWLY WEAKEN. DRIER AIR WILL FOLLOW IN THE WAKE OF THIS FEATURE WHICH WILL ALLOW TEMPERATURES TO DROP OFF A COUPLE DEGREES MORE TONIGHT IN PORTIONS OF NORTHERN UTAH THAN IN PREVIOUS NIGHTS. THE NAM IS ABOUT 2 DEGREES C COOLER AT 850 THAN THE GFS ACROSS NORTHERN UTAH THURSDAY. HAVE DECIDED TO LEAN TOWARD THAT SOLUTION...ESPECIALLY IF WE COOL A FEW MORE DEGREES TONIGHT. ISOLATED THUNDERSTORMS OVER SOUTHERN UTAH MOVING SWIFTLY ENOUGH AS NOT TO PRESENT ANY THREATS OF FLASH FLOODING DESPITE HIGH PWS. THESE STORMS WILL DIE RAPIDLY WITH SUNSET. THE DRIER AREA WILL WORK INTO THE ENTIRE REGION EXCEPT EXTREME SOUTHWEST PORTIONS FOR THURSDAY INTO EARLY FRIDAY. HOWEVER...AS THE RIDGE MOVES EAST OF UTAH BY FRIDAY A MORE MOIST SOUTHWEST FLOW WILL DEVELOP BRINGING A THREAT OF THUNDERSTORMS BACK INTO NORTHERN UTAH AGAIN. TEMPERATURES WILL BE RIGHT BACK TO NEAR TRIPLE DIGITS FRIDAY AND SATURDAY BUT SHOULD BACK OFF SOME AS MORE MOISTURE AS A SLIGHTLY MORE WESTERLY FLOW DEVELOPS. EARLY NEXT WEEK COULD BE INTERESTING AS A RELATIVELY STRONG TROUGH MOVES INTO PAC NW AND AMPLE MOISTURE RESIDES OVER UTAH. THE COMBINATION OF JET DYNAMICS AND MOISTURE COULD BRING WIDESPREAD SHOWERS AND THUNDERSTORMS TO THE REGION. BEST LIFT WILL BE MONDAY NIGHT INTO TUESDAY. WELCOMED COOLING INTO THE LOWER 90S OR EVEN POSSIBLY THE UPPER 80S COULD PREVAIL ACROSS NORTHERN UTAH BY WEDNESDAY IF THE GFS IS CORRECT. && .FIRE WEATHER...WARMING AND DRYING TREND WILL CONTINUE THROUGH FRIDAY AS RIDGE OF HIGH PRESSURE KEEPS NORTHWEST FLOW ALOFT OVER THE STATE THROUGH FRIDAY. RIDGE AXIS IS EXPECTED TO MOVE OVER THE AREA ON FRIDAY AND MOISTURE SPREADS OVER THE AREA RAPIDLY...BEHIND IT. THIS COULD BRING A POSSIBLE THREAT FOR DRY THUNDERSTORMS TO WESTERN VALLEYS. A MOIST AIRMASS WILL REMAIN IN PLACE FOR THE WEEKEND BRINGING SLIGHT COOLING TO THE STATE. A COLD FRONT COULD ENHANCE PRECIPITATION OVER NORTHERN UTAH ON MONDAY AND INCREASE CHANCE OF WETTING RAINS FOR EARLY NEXT WEEK. && .AVIATION. TROUGH MOVING ACROSS NORTHERN UTAH THIS AFTERNOON HAS SPAWNED SCATTERED THUNDERSTORMS. LAKE BREEZE PRESENT AND COULD BE ENHANCED WITH NORTHWEST FLOW FROM UPSTREAM THUNDERSTORMS. CURRENT SPEED PROJECTS THESE SHOWERS AND THUNDERSTORMS TO EFFECT SLC BETWEEN 00Z AND 02Z WITH GUSTY WINDS TO 35 KTS POSSIBLE. LAND-BREEZE PATTERN EXPECTED TO DEVELOP TONIGHT BY AROUND 03Z AS OUTFLOW IN THE WAKE OF THESE STORMS ESTABLISHES THE SOUTHERLY COMPONENT. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...NONE. WY...NONE. && PUBLIC...STRUTHWOLF AVIATION...YOUNG FIRE WX...HALL
