AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
343 AM MDT FRI JUN 5 2009
.SHORT TERM...TODAY THROUGH SATURDAY NIGHT...
WINDY CONDITIONS WILL RETURN TO THE AREA TODAY AS A UPPER LEVEL LOW
PRESSURE SYSTEM OFF THE CENTRAL COAST OF CALIFORNIA HEADS EAST INTO
THE GREAT BASIN. DECENT JET ROTATING AROUND THE BASE OF THE TROUGH
WILL SETTLE IN OVER UTAH TODAY...WITH INCREASING PRESSURE GRADIENT.
DEEP MIXING AIDED BY FEWER CLOUDS WITH DRY SLOT WORKING NORTHEAST
ACROSS THE REGION WILL DRIVE DOWN STRONGER WINDS ALOFT...WITH
FREQUENT WIND GUSTS IN EXCESS OF 45 MPH EXPECTED. AS A RESULT...WILL
GO WITH A WIND ADVISORY FOR THE LOWER ELEVATIONS OF SOUTHEAST UTAH
AND SOUTHWEST COLORADO UP TO THE INTERSTATE 70 CORRIDOR. IN
ADDITION...ISOLATED TO SCATTERED CONVECTION WILL ONCE AGAIN DEVELOP
IN DIFLUENT PATTERN LATER TODAY FURTHER AIDING THE GUSTY WINDS.
COMBINATION OF INCREASING SHEER...HEATING AND APPROACHING WAVE
ASSOCIATED WITH THE EJECTING LOW WILL SET THE STAGE FOR A FAIRLY
ACTIVE LATE AFTERNOON AND OVERNIGHT PERIOD AS STRONGER CONVECTION
GETS ROLLING. COULD SEE A FEW STORMS PRODUCING SEVERE WIND GUSTS OVER
58 MPH AND LARGE HAIL...ALTHOUGH COVERAGE OF SUCH STORMS WILL DEPEND
ON JUST HOW MUCH MOISTURE WE CAN WORK BACK IN LATER THIS AFTERNOON.
MORE ENERGY DIVES DOWN THE PACIFIC COAST AS THIS LEAD SYSTEM EJECTS
OUT...WITH SOUTHWEST FLOW CONTINUING THROUGH SATURDAY. IT DOES APPEAR
THAT THIS LEAD WAVE WILL DO A GOOD JOB OF SWEEPING OUT A LOT OF THE
LINGERING MOISTURE AND STABILIZING CONDITIONS...PROMISING A DOWN DAY
FOR CONVECTION ON SATURDAY. HAVE TRIMMED POPS DOWN SLIGHTLY AS A
RESULT. NO MAJOR SWINGS IN TEMPS EXPECTED THROUGH THE PERIOD WITH
READINGS CONTINUING TO RUN AT TO SLIGHTLY ABOVE SEASONAL NORMS.
.LONG TERM...SUNDAY THROUGH THURSDAY...
FINAL PIECE OF THE WEST COAST LOW EXPECTED TO LIFT NE ACROSS THE
GREAT BASIN ON SUN...AND COULD INTERACT WITH A COLD FRONT DROPPING
DOWN FROM THE NW ACROSS ID-WY SUN NIGHT. WRF MODEL IS THE MOST
GENEROUS WITH AREAL COVERAGE OF PRECIP SUN...BUT AMTS NOT THAT GREAT
AS SW FLOW STILL RELATIVELY DRY. WITH STEEP LAPSE RATES STILL...WILL
GO FOR SCATTERED AFTERNOON AND EVE SHOWERS/THUNDERSTORMS SUNDAY...AND
WITH SOME SEMBLANCE OF AN INVERTED-V SOUNDING DUE TO THE DRIER SFC...
GUSTY OUTFLOW WINDS POSSIBLE FROM STORMS. COOLER AIR MOVES IN BY
MON MORNING...WITH 700 MB TEMPS AROUND ZERO CELSIUS INDICATED ACROSS
THE N. WEAK BAROCLINIC ZONE THEN HANGS ACROSS THE N EARLY NEXT WEEK
IN WESTERLY FLOW FOR A CONTINUED CHANCE OF SHOWERS MAINLY FOR THE
NORTH.
TEMPERATURES WILL BE COOL SUNDAY AND MONDAY THEN SLOWLY MODERATE TO
MORE NORMAL LEVELS LATER NEXT WEEK.
&&
.AVIATION...
SHOWERS AND THUNDERSTORMS WILL ONCE AGAIN DEVELOP ACROSS EASTERN UTAH
AND WESTERN COLORADO LATE THIS MORNING AND CONTINUE THROUGH 06Z THIS
EVENING. STRONG GUSTY WINDS TO NEAR 60 MPH AND LARGE HAIL WILL
ACCOMPANY THE STRONGEST THUNDERSTORMS. NEAR SHOWERS AND
THUNDERSTORMS...EXPECT LOCAL MVFR CONDITIONS AS CIGS AND VSBYS DROP.
EXPECT AREAS OF TURBULENCE AS WELL THROUGH 03Z THIS EVENING WITH
STRONG UPPER LEVEL JET MOVING INTO THE REGION. DRIER CONDITIONS ARE
ANTICIPATED FOR SATURDAY...WITH VFR CONDITIONS EXPECTED.
&&
.HYDROLOGY...
WHILE RUNOFF FROM SNOWMELT WILL BE DECREASING...A PERSISTENT
SUBTROPICAL FLOW OF MOISTURE WILL ALLOW THE THREAT OF SHOWERS AND
THUNDERSTORMS TO CONTINUE INTO THE FIRST HALF OF NEXT WEEK.
THIS PRECIPITATION WILL HELP TO SUSTAIN HIGH RIVER AND STREAM FLOWS
AND MAY EVEN CAUSE SOME MINOR RISES IN WATER LEVELS.
MOST RIVERS AND STREAMS ARE WITHIN THEIR BANKS. HOWEVER...THE EAGLE
RIVER IS CURRENTLY AT BANKFULL AND IS RESULTING IN SOME MINOR
FLOODING OF AGRICULTURAL LAND. A FLOOD ADVISORY CONTINUES FOR THE
EAGLE RIVER NEAR GYPSUM TO ALERT PEOPLE OF HIGH FLOWS.
