Area forecast discussion, Aug 13, 1:35 PM MST, 25 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND JUNCTION CO 235 PM MDT SUN AUG 13 2006 .SHORT TERM (TONIGHT THROUGH TUESDAY)... SHEAR AXIS ALOFT ELONGATED SW TO NE FROM SOUTH CENTRAL UTAH TO NORTH CENTRAL COLORADO IN SOUTHWEST FLOW. THIS APPEARS TO BE THE BEST FOCUS MECHANISM TODAY WITH A FAIR AMOUNT OF CONVECTIVE ACTIVITY THIS AFTERNOON. THE SURFACE ANALYSIS DEPICTS A STATIONARY FRONT POSITIONED OVER NRN UTAH AND NWRN COLORADO...BUT CANNOT FIND THIS FRONT BY LOOKING AT THE SURFACE OBSERVATIONS AND HAVE A HUNCH ITS JUST NORTH OF THE SRN WYOMING BORDER. THERE ARE NUMEROUS STORMS OVER THE UINTA MOUNTAINS BUT SUNNY CONDITIONS OVER THE REST OF WRN WYOMING. MODEL DATA INDICATES THAT THIS SHEAR AXIS WILL BE NEARLY STATIONARY TONIGHT BEFORE GETTING PUSHED EAST BY UPSTREAM NRN GREAT BASIN SHORT WAVE. GIVEN THAT NOCTURNAL ACTIVITY PERSISTED LAST NIGHT ALONG THE SHEAR AXIS...EXPECT SIMILAR CONDITIONS TONIGHT WITH A FEW STORMS THAT CONTINUE OVERNIGHT ALONG THE SAME SHEAR AXIS. THE FLOW ALOFT BACKS AROUND TO A SOUTHERLY COMPONENT MONDAY AFTERNOON THROUGH TUESDAY...WHICH WILL BRING BACK THE DEEPER MONSOONAL MOISTURE THAT IS LURKING OVER ERN ARIZONA AND NEW MEXICO. THE NEXT SURGE WILL REACH THE SOUTH LATE MONDAY AFTERNOON AND EVENING AND THEN SPREAD NORTH MONDAY NIGHT AND TUESDAY. THE GFS AND WRF INDICATE THAT THERE IS A VORT CENTER ASSOCIATED WITH THE NEXT SURGE FOR MONDAY NIGHT...THEREFORE HAVE INDICATED ISOLATED NOCTURNAL STORMS FOR THE SRN ZONES. WITH MORE AVAILABLE MOISTURE ON TUESDAY...CONVECTIVE POTENTIAL WILL BE HIGHER AND THEREFORE WARRANTS HIGHER POPS WITH CHANCE VALUES FOR MOST OF OUR FORECAST AREA. .LONG-TERM (TUESDAY NIGHT THROUGH SUNDAY)... NOT MUCH CHANGE THROUGH FRIDAY...THEN WHAT COULD BE A TURN TO WETTER WEATHER FRIDAY NIGHT THROUGH SUNDAY. MODELS KEEP A LIGHT MONSOONAL PLUME OVER THE SE THIRD OF THE FORECAST AREA TUE NIGHT. THEN A SHORTWAVE PASSING THROUGH THE NORTHERN ROCKIES PROVIDES A MORE WESTERLY COMPONENT TO THE WINDS ALOFT WED THROUGH THU NGT. THIS SHOULD BRING A BRIEF DRIER AND WARMER SPELL...ESPECIALLY OVER NE UTAH AND NW CO WHICH WILL SEE THE LEAST OF THE REMAINING MOISTURE. ON FRIDAY A SIGNIFICANT MONSOONAL SURGE PUSHING NORTH FROM AZ AND NM APPEARS STRONGER IN THE LATEST MODEL RUN. THE MONSOON IS PROJECTED TO SPREAD NORTH AND SHOULD COVER THE FORECAST AREA BY SAT AFTERNOON. HAVE INCREASED THE POPS...CLOUDS AND QPF...AND DECREASED TEMPS THROUGH THE PERIOD. && .GJT WATCHES/WARNINGS/ADVISORIES... .CO...NONE. .UT...NONE. && PF/CJC
