AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND JUNCTION CO 237 PM MDT THU JUL 28 2005 .SHORT TERM (TONIGHT THROUGH SATURDAY)... HIGH PRESSURE REMAINS CENTERED OVER THE REGION...WITH DRY AND STABLE NW FLOW CONTINUING ACROSS MUCH OF EASTERN UTAH AND WESTERN COLORADO. LITTLE CHANGE EXPECTED FROM THIS PATTERN THROUGH FRIDAY MORNING...WITH DRY AND MOSTLY CLEAR CONDITIONS REMAINING IN PLACE. MODELS HAVE STARTED TO BACK OFF THE INCREASE IN LOW/MID LEVEL MOISTURE ACROSS THE NORTHERN ZONES FRIDAY AFTERNOON...AND HAVE TRIMMED POPS BACK SLIGHTLY WITH FCSTD PRECIPITABLE WATER VALUES LOWER THAN WE WERE EARLIER THINKING. BETTER MOISTURE INCREASES THROUGHOUT THE NORTHERN EDGE OF THE RIDGE FRIDAY NIGHT AND SATURDAY. THIS WILL GRADUALLY FILL THROUGHOUT THE RIDGE...RESULTING IN A BETTER CHANCE OF CONVECTION ACROSS EASTERN UTAH AND WESTERN COLORADO ON SATURDAY. LOW LEVELS MAY BE SUFFICIENTLY WET TO PROVIDE STORMS CAPABLE OF PRODUCING WETTING RAINS...ESPECIALLY OVER THE HIGHER ELEVATIONS. ANOTHER WARM AFTERNOON ON FRIDAY WITH H7 TEMPS APPROACHING +19 C...WHICH WOULD BRING MORE TRIPLE DIGIT HEAT TO THE LOWER VALLEYS. .LONG TERM (SATURDAY NIGHT THROUGH THURSDAY)... DGEX AND GFS SHOW PERSISTENT UPPER LEVEL RIDGE REMAINING OVER THE AREA DURING FORECAST PERIOD. SOME MOISTURE WILL BEGIN TO CREEP INTO THE FLOW ALOFT AND SLOWLY MOISTEN THE LOWER LEVELS. THUNDERSTORM DEVELOPMENT MAINLY DURING EACH AFTERNOON AND EVENING...OCCURRING OVER THE HIGHEST TERRAIN INITIALLY, THEN SPREADING TO HIGHER VALLEYS AS MOISTURE WORKS INTO THE LOWER LEVELS. NO SIGNIFICANT TAP TO SUBTROPICAL MOISTURE IS EVIDENT IN DGEX AND GFS, HOWEVER CONTINUED INTENSE AFTERNOON HEATING WILL MAINTAIN THE DAILY INCREASE IN LOCALIZED RAINFALL POTENTIAL. GUSTY WINDS AND FREQUENT CLOUD-TO- GROUND LIGHTNING WILL ACCOMPANY MOST STORM CLOUDS. POSITIVE TILT IN RIDGE AXIS INITIALLY...LIKELY TRANSITIIONING TO A NEGATIVE TILT BY WEDNESDAY. THIS NEGATIVE TILT MAY ALLOW INCREASED MOIST ADVECTION FROM THE SUBTROPICS AND A WEAK UPPER LEVEL TO MOVE INTO NORTH CENTRAL COLORADO. && .GJT WATCHES/WARNINGS/ADVISORIES... .CO...NONE. .UT...NONE. && JDC/DEZ
