AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND JUNCTION CO 414 AM MDT SAT AUG 26 2006 .SHORT TERM (TODAY THROUGH SUNDAY NIGHT)... AN ACTIVE WEATHER DAY ON TAP FOR EASTERN UTAH AND WESTERN COLORADO TODAY WITH A FEW SEVERE THUNDERSTORMS POSSIBLE. A CLOSED UPPER LOW IS SITUATED OVER THE NORTHERN GREAT BASIN EARLY THIS MORNING. LARGE SCALE ASCENT AHEAD OF THIS SYSTEM AND SHORTWAVES EJECTING OUT OF THE TROUGH HAVE BEEN GENERATING THUNDERSTORMS ACROSS MUCH OF THE AREA ALL NIGHT. THIS SYSTEM WILL MOVE ACROSS NORTHERN UTAH TODAY AND THEN ACROSS WESTERN COLORADO TONIGHT. SOME DRIER AIR IS MOVING INTO THE AREA EARLY THIS MORNING ON THE BACK SIDE OF A SHORTWAVE WHICH WILL HELP BREAK CLOUDS UP AND ALLOW FOR SOME SUNSHINE AND DESTABILIZATION OF THE AIRMASS THIS MORNING. RESPECTABLE CAPE VALUES AND PRETTY GOOD SHEAR ACROSS THE AREA WILL RESULT IN STRONG STORMS THIS AFTERNOON WITH A SOME LARGE HAIL AND DAMAGING WINDS POSSIBLE WITH A FEW STORMS. STORMS WILL BE MOVING ALONG AT A PRETTY GOOD CLIP BUT WILL NEED TO WATCH FOR TRAINING STORMS DUMPING HEAVY RAIN. GOOD FORCING ALONG WITH A COLD FRONT MOVING ACROSS THE AREA WILL KEEP STORMS FIRING THROUGH THE EVENING WITH A GRADUAL DECREASING TREND LATE TONIGHT AS THE BEST FORCING SHIFTS EAST AND THE LOWER ATMOSPHERE BECOMES MORE STABLE. NORTHEAST FLOW TO DOMINATE ACROSS THE AREA SUNDAY AS THE UPPER LOW OPENS UP AND MOVES ONTO THE HIGH PLAINS. OROGRAPHIC FORCING AND DAYTIME INSTABILITY WILL ACT ON LINGERING MOISTURE TO PRODUCE ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE DAY SUNDAY...ESPECIALLY ACROSS THE CENTRAL AND NORTHERN MOUNTAINS. THE ATMOSPHERE WILL STABILIZE QUICKLY WITH SUNSET SUNDAY EVENING BRINGING SHOWERS AND THUNDERSTORMS TO AN END. BELOW NORMAL TEMPERATURES EXPECTED THROUGH THE WEEKEND. LINDQUIST .LONG-TERM (MONDAY THROUGH FRIDAY)... A RIDGE OF HIGH PRESSURE WILL BUILD OVER THE WEST ON MONDAY. NORTHWEST FLOW ALOFT WILL CONTINUE TO USHER IN DRIER AIR...ALTHOUGH WRF/GFS DO INDICATE ENOUGH MOISTURE AND INSTABILITY LINGERING AROUND TO WARRANT A CONTINUED MENTION OF ISOLATED MOUNTAIN THUNDERSTORMS OVER WEST CENTRAL COLORADO. ACTIVITY ON TUESDAY LOOK EVEN MORE ISOLATED AS THE RIDGE AXIS MOVES OVERHEAD. NEXT STRONG FALL-LIKE TROUGH IS EXPECTED TO MOVE THROUGH THE PACNW ON WEDNESDAY...THEN PROGRESS SLOWLY EASTWARD INTO THE INTERMOUNTAIN WEST THURSDAY AND FRIDAY. ALTHOUGH MODELS HAVE BEEN HAVING SOME DIFFICULTY PINNING DOWN THE TIMING...THINK TIMING ON TONIGHTS 00Z RUN OF THE GFS LOOKS PRETTY GOOD. IT IS MORE IN LINE WITH THE 12Z EURO AND THE GFS ENSEMBLE MEAN FROM 18Z. THIS SCENARIO WILL ALLOW MOISTURE TO INCREASE A LITTLE ON WEDNESDAY AS SOME MONSOONAL MOISTURE GETS PULLED INTO THE SOUTHWEST FLOW. MORE MOISTURE IS THEN EXPECTED TO MOVE IN ON THURSDAY AS THE TROUGH AXIS MOVES INTO UTAH. DYNAMICS ASSOCIATED WITH THE APPROACHING UPPER TROUGH WOULD FAVOR THE NORTHERN PORTION OF THE FORECAST AREA AS FAR AS PRECIPITATION CHANCES ARE CONCERNED. MODELS PUSH A WEAK COLD FRONT THROUGH THE CWA LATE THURSDAY INTO FRIDAY. INHERITED POPS COVERED THIS WELL AND ONLY A FEW TWEAKS WERE MADE. && .GJT WATCHES/WARNINGS/ADVISORIES... CO...NONE.
