Area forecast discussion, Jun 12, 3:02 AM MST, 1 hour 8 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND JUNCTION CO 402 AM MDT SAT JUN 12 2010 .SHORT TERM...TONIGHT THROUGH SUNDAY... DEEP UPPER LEVEL LOW CONTINUES TO SETTLE IN OVER SOUTHERN NEVADA EARLY THIS MORNING. THIS IS BRINGING BROAD CYCLONIC FLOW OVER THE REGION WITH WESTERN COLORADO AND EASTERN UTAH BEING INFLUENCED BY STRONG DIFLUENCE ALOFT. DECENT MOISTURE IN PLACE WITH PRECIPITABLE WATER VALUES AROUND THREE QUARTERS OF AN INCH. THIS WILL RESULT IN EFFICIENT RAIN PRODUCERS WITH QPF AMOUNTS VARYING OVER A HALF INCH POSSIBLE BY EARLY SUNDAY. CLOUD COVER AND SHOWERS WILL CONTINUE TO KNOCK BACK TEMPS AND SHAVED ANOTHER 2 TO 3 DEGREES OF FCST MAX TEMPS TODAY...WITH 60S AND 70S COMMON FOR THE LOWER ELEVATIONS. FAR CRY FROM THE TRIPLE DIGIT HEAT WE WERE EXPERIENCING EARLIER IN THE WEEK. DUE TO THE CLOUD COVER AND COOLER TEMPS...POTENTIAL FOR STRONG TO SEVERE STORMS WILL BE INHIBITED. HOWEVER...ANY BREAKS IN THE CLOUD COVER WILL ALLOW FAIRLY QUICK HEATING TO OCCUR...SO STILL SOME POTENTIAL FOR STRONGER STORMS...WHICH WOULD BE CAPABLE OF PRODUCING GUSTY WINDS AND SMALL HAIL. CONVECTIVE ACTIVITY CONTINUES THROUGH AT LEAST MIDDAY SUNDAY AS THE UPPER LEVEL LOW SLOWLY FILLS AND LIFTS NORTHEAST ACROSS THE REGION. AS COLDER AIR FILTERS...EXPECT SNOW LEVELS TO DROP TO AROUND 10K BY SUNDAY MORNING...WITH POSSIBLY DOWN TO 9K OVER THE NORTHERN ZONES. WITH THE BULK OF ACCUMULATING SNOW ABOVE THE 10K LEVEL...WILL NOT BE ISSUING ANY WINTER HIGHLIGHTS...BUT SOMETHING FOR THOSE HEADED OUTDOORS TO BE AWARE OF. SHOWERS EXPECTED TO DECREASE BY SUNDAY NIGHT WITH DRIER CONDITIONS MOVING IN BY EARLY MONDAY. THIS WILL ALLOW SKIES TO CLEAR AND WILL RESULT IN MUCH COOLER CONDITIONS FOR EARLY MONDAY MORNING. SOME HIGH VALLEY FREEZES POSSIBLE AND WILL BE WATCHING THIS POTENTIAL CLOSELY OVER THE NEXT 24 HOURS. .LONG-TERM...MONDAY THROUGH SATURDAY... EARLY IN THE PERIOD...MODELS HAVE TRENDED JUST A LITTLE SLOWER WITH EACH RUN TO KEEP SOME TROUGHINESS LINGERING OVER THE FORECAST AREA ON MONDAY. THEREFORE SOME SHOWER ACTIVITY WILL CONTINUE THROUGHOUT MONDAY...ESPECIALLY OVER THE NORTH. THEN A FAST MOVING SHORTWAVE RIDGE PASSES OVER THE AREA MONDAY NIGHT AS THE NEXT LOW PRESSURE SYSTEM MOVES ONSHORE OVER THE PACIFIC NORTHWEST. STILL SOME UNCERTAINTY IN THE HANDLING OF THIS SYSTEM AS IT MOVES OVER THE WESTERN CONUS. THE MORE CONSISTENT ECMWF KEEPS MOST ENERGY TO OUR NORTH AS IT MOVES THE LOW TO THE EAST ON THURSDAY...KEEPING THE FORECAST AREA DRY. THE 12Z GFS IS MORE AMPLIFIED AND SLOWER...BUT WILL LEAVE THE DRY FORECAST FOR NOW. TEMPERATURE START OUT RATHER COOL...THEN REACH NEAR NORMAL VALUES ON TUESDAY. WE THEN WARM UP JUST A LITTLE MORE FOR THE REMAINDER OF THE PERIOD. && .AVIATION... WIDESPREAD SHOWERS AND THUNDERSTORMS WILL BLANKET MUCH OF WESTERN COLORADO AND EASTERN UTAH THROUGH EARLY SUNDAY. EXPECT WIDESPREAD MVFR CIGS TODAY AND TONIGHT...ESPECIALLY OVER THE MOUNTAINS WITH LOCAL IFR CONDS POSSIBLE NEAR THE STRONGER SHOWERS AND THUNDERSTORMS. && .HYDROLOGY... FLOWS CONTINUED TO GRADUALLY DECREASE ALONG MANY OF THE HEADWATER STREAMS AND CREEKS IN NORTH-CENTRAL COLORADO AND NORTHEASTERN UTAH. THE RETURN OF COOLER TEMPERATURES THIS WEEKEND COMBINED WITH THE DEPLETION OF SNOWPACK IN THE MOUNTAINS OF NORTHEASTERN UTAH AND NORTH-CENTRAL COLORADO WILL RESULT IN DECREASED FLOWS AND LOWERING RIVER LEVELS. HOWEVER...THE POTENTIAL FOR RAIN THIS WEEKEND IN THE COLORADO RIVER HEADWATERS REGION AND THE YAMPA RIVER HEADWATERS REGION IS BEING CLOSELY MONITORED. THE RIVER MODELS HAVE BEEN RERUN USING HIGHER PRECIPITATION AMOUNTS AND THE IMPACT ON THE FORECAST RIVER FLOWS APPEARS TO BE SMALL. RECREATIONALISTS SHOULD USE CAUTION WHEN BOATING AND RAFTING IN THE COLD...FAST FLOWING RIVER WATERS. LARGE QUANTITIES OF DEBRIS HAVE BEEN OBSERVED IN MANY RIVERS. ALSO...THE HIGH WATERS CAN QUICKLY ERODE RIVER BANKS MAKING THEM UNSTABLE TO WALK ON OR NEAR. && .GJT WATCHES/WARNINGS/ADVISORIES... .CO....NONE. .UT....NONE.
