Area forecast discussion, Jul 9, 2:00 PM MST, 6 hours 40 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND JUNCTION CO 300 PM MDT SUN JUL 9 2006 .SHORT TERM (TONIGHT THROUGH TUESDAY)... THE ATMOSPHERE WILL REMAIN VERY MOIST THIS EVENING AS AN UPPER LEVEL LOW MOVES INTO SOUTHWESTERN WYOMING. THE PRIMARY CONCERN THIS EVENING REMAINS TO BE THE HEAVY RAIN POTENTIAL ACROSS THE CWA. GOOD LIFT...AMPLE MOISTURE...AND ADDITIONAL INSTABILITY DUE TO AFTERNOON HEATING HAS ALLOWED STORMS TO INCREASE IN INTENSITY THE LAST FEW HOURS. IN ADDITION MORE VIGOROUS THUNDERSTORMS HAVE RECENTLY DEVELOPED ACROSS UTAH AND ARIZONA WHERE PARTIAL CLEARING OCCURRED THIS AFTERNOON. WITH THESE STRONGER STORMS...SMALL HAIL WILL ALSO BE POSSIBLE THROUGH THE EARLY EVENING HOURS. SHOWERS AND THUNDERSTORMS WILL DIMINISH LATE THIS EVENING AS A WEAK SHORTWAVE RIDGE MOVES THROUGH THE AREA. BY LATE TONIGHT MODELS ARE SHOWING A WEAKER WAVE...CURRENTLY OVER NEVADA...WILL MOVE INTO WESTERN PORTIONS OF CWA. THIS WAVE WILL BRING A CHANCE OF SHOWERS AND THUNDERSTORMS OVER THE AREA ON MONDAY WITH BEST CHANCE OVER THE HIGHER TERRAIN. CONDITIONS WILL QUICKLY IMPROVE ON MONDAY NIGHT AS DRIER AIR MOVES ACROSS THE AREA. RIDGE WILL BUILD OVER THE REGION ON TUESDAY BUT WITH AMPLY RESIDUAL MOISTURE HAVE KEPT CHANCE POPS MAINLY OVER THE MOUNTAIN LOCATIONS. EXPECT TEMPERATURES TO MODERATE TO NEAR NORMAL BY TUESDAY. .LONG-TERM (TUESDAY NIGHT THROUGH SUNDAY)...WITH EACH RUN...MODELS ARE A LITTLE MORE SURE OF A DRIER PATTERN THIS PERIOD. THE MOISTURE PLUME FROM MEXICO GETS PINCHED OFF QUITE A BIT...AND PUSHED EAST. THE GFS TRIES TO RE-ESTABLISH THE THETA-E RIDGE OVER THE REGION BY LATE IN THE WEEK...BUT TO A MUCH LESSER DEGREE THAN THIS PRESENT SURGE. THE ECMWF HOWEVER KEEPS THE AREA DRY THROUGH THE END OF THE PERIOD. FEEL THAT IN THIS DRIER PATTERN WE WILL BE IN A LIGHTER AND MORE DIURNAL AND TERRAIN DRIVEN THUNDERSTORM CYCLE WITH CONVECTION HARD TO FIRE OVER THE VALLEYS. SO HAVE REDUCED MAINLY VALLEY POPS TO THE ALREADY DRIER FORECAST. HIGH TEMPS WILL INCREASE WITH READINGS AT OR ABOVE NORMAL THROUGH THE PERIOD. ALSO EXPECT WE WILL SEE A LARGER DIURNAL TEMP SPREAD WITH DRIER NIGHTTIME CONDITIONS. && .GJT WATCHES/WARNINGS/ADVISORIES... .CO...NONE. .UT...NONE. && MPM/ELH
