AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
205 PM MDT SUN JUN 13 2010
.UPDATE...EXCESS RAINFALL FROM THUNDERSTORMS AND SHOWERS OVER THE
PAST 24 HOURS HAS CAUSED SOME SMALL STREAM FLOODING WITHIN ARCHES
NATIONAL PARK. LATEST RADAR IMAGERY HIGHLIGHTS CONTINUED RAINFALL
FOR NEXT FEW HOURS SO ISSUED FLOOD ADVISORY FOR ARCHES NATIONAL
PARK AND ADJACENT AREAS. AS UPPER LOW MOVES OUT OF AREA...CAN
EXPECT PRECIP TO SLOWLY TAPER OFF TONIGHT AND TOMORROW.
&&
.PREV DISCUSSION... /ISSUED 205 PM MDT SUN JUN 13 2010/
.SHORT TERM...TONIGHT THROUGH TUESDAY...
CLOSED UPPER LOW OVER UTAH AND WRN COLORADO HAS KEPT THE AIR MASS
UNSETTLED WITH NUMEROUS SHOWERS AND A FEW STORMS. THE DEEP LAYERED
SHEAR HAS SHIFTED TO THE PLAINS AND THE DYNAMICAL FORCING IS
CONSIDERABLY WEAKER...THE RADAR RETURNS REFLECT THIS TREND WITH
WEAKER AND SLOWER MOVING CELLS.
UPPER LOW HAS LOST ITS UPSTREAM COLD AIR SOURCE AND CURRENTLY
FILLING. THE UPPER LOW WILL TRACK NORTHEAST AND REDEVELOP OVER THE
DAKOTA STATES...IN THE PROCESS EXPECT SHOWERS TO TAPER OFF OVERNIGHT
BUT ISOLATED SHOWERS WILL PERSIST ACROSS THE NORTH BEYOND MIDNIGHT.
POSITIVE TILT TROUGH DRAGS ACROSS THE FORECAST AREA ON MONDAY...AND
COMBINED WITH SURFACE HEATING WILL TRIGGER ANOTHER ROUND OF
SCATTERED SHOWERS WITH THE PRIMARY FOCUS OVER THE RIDGES AND
MOUNTAINS. ERN UTAH WILL BE TRENDING DRIER AS THIS PORTION OF THE
FORECAST AREA WILL BE BEHIND THE TROUGH AXIS BY AFTERNOON.
MONDAY NIGHT AND TUESDAY...NEXT UPSTREAM TROUGH WILL AMPLIFY OVER
THE PACIFIC NORTHWEST STATES AND THAT RESULTS IN DRIER SOUTHWEST
FLOW OVER THE THE SRN HALF OF THE ROCKY MOUNTAIN STATES. LINGERING
SHOWERS WILL END EARLY MONDAY NIGHT WITH CLEARING FROM THE WEST.
MOSTLY SUNNY CONDITIONS EXPECTED ON TUESDAY WITH RECOVERING TEMPS
THAT WILL BE TYPICAL FOR JUNE.
.LONG-TERM...TUESDAY NIGHT THROUGH SUNDAY...
LITTLE CHANGE TO THE CURRENT FORECAST FOR THIS PERIOD. A MEAN
LONGWAVE TROUGH IS EXPECTED TO REMAIN NEAR THE WEST COAST WITH
PACIFIC SHORTWAVE TROUGHS ROTATING THROUGH IT AND ACROSS THE WEST.
THE MOST SIGNIFICANT OF THESE SHORTWAVES IS EXPECTED TO CLIP NE UT/NW
CO WED NIGHT AND THU AS IT PASSES. ECWMF NOW THE SLOWER AND DEEPER
THAN THE GFS WITH THIS TROUGH. BOTH MODELS DO NOT SHOW MUCH MOISTURE
FOR OUR AREA BUT WILL LIKELY GENERATE INCREASED SURFACE WINDS WED-
THU. THIS MAY INCREASE FIRE WEATHER CONCERNS OF WIND AND LOW HUMIDITY
AFTER MIDWEEK AS A RESULT. SOME RIDGING EXPECTED FRI BEHIND THE
TROUGH AS BOTH THE ECWMF AND GFS DEVELOP A SRN STREAM JET ACROSS SRN
CA TO THE ROCKIES BY SAT. MODELS INDICATE CONTINUED DRY SW FLOW NEXT
WEEKEND...WHICH WOULD BE TRUE CLIMATOLOGICALLY FOR THIS TIME OF
YEAR...BUT RECENT STORMS SEEMED TO TAP A BIT MORE MOISTURE THAN
ORIGINALLY FORECAST. WITH THAT IN MIND...WILL KEEP ISOLATED MTN
THUNDERSTORMS IN THE FORECAST SAT-SUN. TEMPS NEAR NORMAL FOR MIDWEEK
WILL WARM BY THE WEEKEND.
&&
.AVIATION...
NUMEROUS SHOWERS WITH SCATTERED THUNDERSTORMS WILL BLANKET
MUCH OF WESTERN COLORADO AND EASTERN UTAH THROUGH EARLY THIS EVENING.
EXPECT MVFR CIGS...ESPECIALLY OVER THE MOUNTAINS WITH LOCAL IFR
CONDITIONS POSSIBLE NEAR STRONGER SHOWERS AND THUNDERSTORMS.
SHOWERS WILL TAPER OFF TO ISOLATED OVERNIGHT. ERN UTAH WILL BE
MOSTLY DRY ON MONDAY...BUT DIURNALLY DRIVEN CONVECTION WILL OCCUR
OVER THE WESTERN COLORADO MOUNTAINS AFTER 17Z.
&&
.HYDROLOGY...
THE ELK RIVER NEAR MILNER HAS DROPPED BELOW FLOOD STAGE AND UNLESS
SIGNIFICANT RAINFALL OCCURS AGAIN THIS AFTERNOON/EVENING IN ITS CATCH
BASIN...IT IS FORECAST TO REMAIN BELOW FLOOD STAGE. OTHER RIVERS
THROUGHOUT WEST-CENTRAL AND NORTHWEST COLORADO AND NORTHEAST UTAH
WILL CONTINUE RUNNING FULL BUT WITHIN THEIR BANKS. SOME LARGER MAIN
STEAM RIVER LEVELS IN THE NORTH AND CENTRAL AREAS MAY SEE A SLIGHT
RISE MON-TUE AS RUNOFF FROM SATURDAY/S WIDESPREAD RAINFALL CONTINUES
TO MAKE IT WAY DOWNSTREAM. HOWEVER...THE GENERAL TREND SHOULD BE ONE
OF GRADUALLY DECREASING FLOW THROUGH THE UPCOMING WEEK.
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.
