AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SALT LAKE CITY UT 415 PM MDT THU SEP 7 2006 .SYNOPSIS...A LOW PRESSURE SYSTEM OVER SOUTHERN UTAH WILL MOVE SLOWLY NORTHEAST ACROSS THE STATE THROUGH FRIDAY MORNING. THIS LOW PRESSURE WILL MOVE INTO COLORADO FRIDAY NIGHT...FOLLOWED BY AN UPPER LEVEL RIDGE FOR THE WEEKEND. && .DISCUSSION...UPPER LOW BECOMING BETTER ORGANIZED OVER S/CNTRL UTAH THIS AFTERNOON. CONVECTION HAS BEEN ON A STEADY INCREASE OVER SRN/CNTRL UTAH...ESPECIALLY IN THE WRAP AROUND W-NW FLANK OF THE LOW. THIS FEATURE WILL LIKELY LINGER OVER THE SOUTH THIS EVENING... THEN WORK IN NE UTAH BY FRIDAY MORNING. THE SLOW GRINDING NATURE OF THIS FEATURE COULD LEAD TO MORE THAN A FEW AREAS RECEIVING HEAVY PRECIP INTO AND THROUGH FRIDAY. UP NORTH CLOUD COVER AND WEAK DYNAMIC FORCING HAVE KEPT CONVECTION ON THE WEAK SIDE THIS AFTERNOON. THE APPARENT VORTICITY MAX MOVING SLOWLY SOUTH OUT OF SRN IDAHO WILL SETTLE INTO EXTREME NE NV OVERNIGHT. MODELS DO NOT MAKE MUCH OF THIS FEATURE...YET HAS EXPANDED NEAR THE CORE OF THIS FEATURE PAST COUPLE OF HOURS. MODELS DO HOLD THE VORTICITY MAX BACK IN NV INTO FRIDAY. NOT REALLY CONFIDENT THAT THE MODELS ARE TREATING THIS FEATURE PROPERLY. SUSPECT THIS FEATURE WILL MOVE INTO NRN UTAH DURING THE DAY FRIDAY PRODUCING CONVECTION OVER N/CNTRL UTAH. UPPER RIDGE SHOULD SLIDE EAST INTO UTAH FOR THE WEEKEND. RESIDUAL MOISTURE ASSOCIATED WITH THE EXITING UPPER LOW SHOULD FEED ANY DIURNAL CONVECTION THAT DEVELOPS BOTH DAYS. BEYOND SUNDAY CONFIDENCE IN THE MODELS...PARTICULARLY THE GFS...IS LOW. THE GFS HAS BOUNCED ALL OVER THE PLACE WITH THE SPLITTING TROUGH OFF THE PACIFIC NW COAST. ALL MODEL SOLUTIONS ASIDE...WOULD THINK THE BEST SOLUTION WOULD BE FOR A WEAKENING VORTICITY LOBE MOVING THROUGH UTAH LATE SUNDAY NIGHT/MONDAY...WITH SOME CHANCE THAT A WEAK CIRCULATION MAY HANG BACK OVER NV FOR THE FIRST HALF OF THE WEEK. FOR NOW WILL KEEP MODEST POPS SUNDAY/MONDAY...THEN TEND DOWN FOR THE BALANCE OF THE EXTENDED FORECAST. && .AVIATION...THUNDERSTORMS DEVELOPING OVER NORTHERN UTAH WILL REMAIN THROUGH THIS EVENING. A 30 PERCENT CHANCE THAT THE TERMINAL WILL BE AFFECTED BY A THUNDERSTORM EXISTS. && .FIRE WEATHER...UPPER LOW OVER SRN UTAH LOOKS TO GENERATE FAIRLY WIDESPREAD...AND FOR THE MOST PART...WETTING RAIN TONIGHT ACROSS SRN/CNTRL/ERN UTAH. THESE RAINS WILL CONTINUE FOR AT LEAST E/CNTRL THROUGH NE UTAH THROUGH FRIDAY AS THE LOW DRIFTS TO THE NE. THE UPPER RIDGE MOVING IN FOR THE WEEKEND WILL REDUCE THE THREAT FOR CONVECTION...THOUGH ENOUGH MOISTURE WILL LINGER FROM THE LATE WEEK STORM TO GENERATE A FEW AFTERNOON/EVENING THUNDERSTORMS OVER THE HIGHER TERRAIN. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...NONE. WY...NONE. && PUBLIC/FIRE WX....CONGER AVIATION....YOUNG
