AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND JUNCTION CO 302 AM MST FRI MAR 9 2007 .SHORT TERM (TODAY THROUGH SATURDAY NIGHT)...SHORTWAVE RIDGING THIS MORNING WILL GIVE WAY TO A MORE WESTERLY FLOW AS THE NEXT FEW SHORTWAVE TROUGHS MOVE TOWARD THE AREA. NO PRECIPITATION IS EXPECTED TO OCCUR TODAY...HOWEVER THERE MAY BE SOME PROBLEMS WITH FOG THIS MORNING. SURFACE OBSERVATIONS AND WEB CAMS ARE INDICATING PATCHY DENSE FOG AT CAG AND HDN...WITH FOG DEVELOPING IN THE STEAMBOAT SPRINGS AREA. WILL KEEP AN EYE ON THIS THIS MORNING FOR POTENTIAL ADVISORIES. PATCHY FOG WILL ALSO LIKELY DEVELOP THIS MORNING ALONG THE I-70 CORRIDOR BUT WILL PROBABLY NOT BE WIDESPREAD ENOUGH TO BE OF GREAT CONCERN. GOOD MODEL AGREEMENT WITH FIRST SHORTWAVE MOVING THROUGH TONIGHT. THIS INITIAL CHUNK OF ENERGY DOES NOT LOOK VERY STRONG OR ORGANIZED BUT WITH MOISTURE IN PLACE FELT ADDING LOW END POPS TO THE NORTHERN MOUNTAINS THIS EVENING WAS JUSTIFIED. NEXT STRONGER SHORTWAVE TROUGH WILL THEN BEGIN TO AFFECT THE FORECAST AREA AFTER MIDNIGHT. THIS ONE WILL SPREAD WIDESPREAD PRECIPITATION ACROSS THE FORECAST AREA ON SATURDAY AHEAD OF AN ASSOCIATED COLD FRONT. MODELS ARE INDICATING GOOD LIFT IN THE LEFT EXIT REGION OF SEASONABLY STRONG JET STREAK...SOME MODEST FRONTOGENESIS...AND STEEP LAPSE RATES. GFS MODEL IS HITTING THE SYSTEM MUCH STRONGER THAN THE WRF MODEL... WHICH SEEMS TO BE TRENDING STRONGER WITH EACH RUN. WENT CLOSER TO THE GFS FOR POPS/QPF FOR SATURDAY MORNING AND CONTINUED LIKELY MENTIONS FOR THE HIGHER TERRAIN ON SATURDAY AFTERNOON. ALSO ADDED THUNDERSTORM MENTION FOR SATURDAY WITH NEGATIVE LIS FORECAST. WITH WIDESPREAD PRECIPITATION AND CONVECTION...MAY NEED SOME SNOW ADVISORIES FOR THE NORTHERN AND CENTRAL MOUNTAINS ON SATURDAY. .LONG TERM (SUNDAY THROUGH THURSDAY)... NWLY FLOW DIMINISHES ON SUNDAY WITH HEIGHTS CONTINUING TO RISE ACROSS THE FORECAST AREA. THIS SETS THE STAGE FOR WARM AND DRY CONDITIONS AS WE ENTER THE NEW WORK WEEK WITH TEMPERATURES RUNNING WELL ABOVE SEASONAL NORMS THROUGH TUESDAY. THE RIDGE STARTS TO FLATTEN ON TUESDAY AS A SERIES OF SHRTWVS PASS THROUGH THE NRN ROCKIES. THIS EVENTUALLY RESULTS IN NEARLY ZONAL FLOW ACROSS MUCH OF THE U.S... WITH BEST ENERGY REMAINING TO OUR NORTH. SO DRY CONDITIONS EXPECTED TO PERSIST THROUGH MIDWEEK. LATEST GFS RUN BACKED OFF THE SHALLOW TROUGHINESS FOR LATER NEXT WEEK...DOING NEARLY A 180 AND HINTING AT MORE RIDGING BUILDING BACK INTO THE AREA...WHICH IS MORE IN LINE WITH THE LATEST ECMWF RUN. THIS WOULD KEEP CONDITIONS ON THE MILD AND DRY SIDE THROUGH THE REMAINDER OF THE WEEK. && .GJT WATCHES/WARNINGS/ADVISORIES... .CO...NONE. .UT...NONE. HLO/JDC
