AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
400 AM MDT THU MAY 26 2011

.SHORT TERM...TONIGHT THROUGH FRIDAY...
WINDY DAY ON TAP AS 130 KNOT PACIFIC JET PUNCHES ACROSS THE GREAT
BASIN AND REACHES NW COLORADO LATE THIS AFTERNOON.  STRONG SHORT WAVE
OVER THE PACIFIC NORTHWEST LIFTS NORTHEAST TOWARD MONTANA...BUT THE
SURFACE FRONT MANAGES TO REACH NORTHEAST UTAH THIS AFTERNOON.  THE
STRONG WESTERLY JET DRIVES THE FRONT ACROSS NORTHWEST COLORADO
THIS EVENING.  THIS WILL SUBSTANTIALLY TIGHTEN THE PRESSURE AND
SURFACE GRADIENT.  WITH SURFACE CYCLOGENESIS ACROSS COLORADO TODAY...
THE AIR MASS BECOMES WELL MIXED AND ALLOWS THE STRONG MID LEVELS
WINDS TO MIX TO THE VALLEY FLOORS.  WILL HOIST A WIND ADVISORY FOR
NEARLY ALL THE VALLEYS THIS AFTERNOON THROUGH THE EARLY EVENING.
WITH RESPECT TO PRECIPITATION...THE STRONGEST DYNAMICAL FORCING STAYS
WELL NORTH OF OUR FORECAST AREA BUT THEIR IS SOME LIFT ASSOCIATED
WITH THE FRONT.  SCATTERED SHOWERS AND A POSSIBLE THUNDERSTORM
EXPECTED OVER THE HIGHER TERRAIN OF NORTHWEST COLORADO...BUT NOT
MUCH PRECIPITATION SOUTH OF THE INTERSTATE.

STRONG GRADIENT FLOW CONTINUES INTO FRIDAY AND AFTERNOON WINDS WILL
BE NEAR WIND ADVISORY CRITERIA ONCE AGAIN.  THE THERMAL GRADIENT
WILL NOT BE AS STRONG AND THE COLD FRONT WILL HAVE SAGGED TO NEAR
THE SOUTHERN BORDER OF UTAH AND COLORADO...RESULTING IN "NOT AS
WINDY" CONDITIONS BUT STILL VERY WINDY.  IN THE POST FRONTAL
ENVIRONMENT...TEMPERATURES WILL BE A FEW DEGREES COOLER.  WITH THE
EXCEPTION OF SOME MID/HI LEVEL CLOUDS...THERE IS NOT MUCH MOISTURE
ENTRAINED IN THIS WESTERLY FLOW.  STRONG FLOW AND SOME MOISTURE
WILL RESULT IN SOME LIGHT OROGRAPHIC SHOWERS ON WESTERN ASPECTS
FRIDAY AFTERNOON AND NIGHT.

.LONG TERM...SATURDAY THROUGH WEDNESDAY...

FRONT WILL BE FORCED THROUGH NORTHERN CWA BY SUNRISE SATURDAY
BECOMING ALIGNED PARALLEL AND JUST OF NORTH OF I-70 UNDERNEATH A
CORE OF MODERATELY FAST ZONAL FLOW. LIFT OVER THIS BOUNDARY LOOKS TO
FAVOR SHOWERS AND THUNDERSTORMS ACROSS THE HIGHER TERRAIN TO THE
NORTH WITH SOUNDINGS SHOWING THE PERSISTENT ASCENT WILL BRING
SHOWERS DOWN TO THE VALLEYS AND HAVE CONTINUED THE TREND OF
INCREASING POPS FOR THE AFTERNOON AND EVENING HOURS. SOUTH OF THIS
BOUNDARY BUFKIT PROFILES AND MODEL GUIDANCE CONTINUE TO SHOW BREEZY
TO WINDY CONDITIONS WITH TEMPERATURES PUSHING UP NEAR NORMAL
LEVELS...WHILE UP NORTH CLOUDS AND PRECIPITATION WILL KEEP THINGS
QUITE A BIT COOLER. AS FOR WINDS MAIN CONCERN WILL CENTER AROUND
CONVECTION TAPPING INTO THE STRONGER SHEAR ALOFT AND BRINGING SOME
HIGHER GUSTS TO THE SURFACE.

HOWEVER THE WIND SCENARIO LOOKS MORE LIKELY ON SUNDAY AS THE WESTERN
TROF DIGS INTO THE GREAT BASIN. UPPER FLOW WILL TURN MORE SOUTHERLY
AND TIGHTEN AS THE TROF APPROACHES AND SQUEEZED THE ROCKIES BETWEEN
STRENGTHENING HIGH PRESSURE OVER THE PLAINS AND SOUTHEAST CONUS.
THIS FLOW WILL PUSH THE SURFACE FRONT BACK NORTHWARD THROUGH THE DAY
USHERING IN DRIER AND WARMER AIR FROM THE DESERT SW REGION.
GUIDANCE ATTM IS SHOWING SOME VERY STRONG WINDS...IN HIGHLIGHT
TERRITORY...AND THIS TREND WILL NEED TO BE MONITORED. LARGE SCALE
ASCENT WILL BE INCREASING THROUGH THE AFTERNOON WITH TROF MOVING
INTO WESTERN UTAH...FORCING THE UPPER JET AXIS INTO WESTERN
COLORADO. SHEAR AND INSTABILITY LOOKS TO BE JUST ENOUGH TO FORM SOME
HIGH BASED STORMS IN THE AFTERNOON...ESPECIALLY IN THE NORTHERN CWA
WHERE MOISTURE WILL BE BETTER. THIS MAY SERVE TO DRIVE SOME OF THE
STRONGER WINDS ALOFT TO THE SURFACE WITH BUFKIT SOUNDINGS SHOWING
OVER 60KT GUST POTENTIAL AT THE TOP OF THE INVERTED V PROFILE.
TEMPERATURES LOOK TO PEAK AT OR SLIGHTLY ABOVE NORMAL LEVELS.

THE UPPER LOW WILL SWING NORTHWARD FROM W.UTAH INTO CENTRAL WYOMING
SUNDAY NIGHT...PUSHING STRONG WAVE AND JET MAXIMA THROUGH NORTHWEST
COLORADO WHILE DRIVING A COOL FRONT EASTWARD. WILL TREND POPS UPWARD
EARLY IN THIS PERIOD BUT STRONG SUBSIDENCE BEHIND THE TROF AXIS
THROUGH MONDAY MORNING AND DRIER AIR MOVING IN FROM THE WEST WILL
LESSEN THE THREAT OF PRECIP THROUGH THE DAY. MAY GET A SMALL BREAK
FROM THE WINDS BUT STEEPENING LAPSE ACROSS NORTHERN CWA LOOK
SUFFICIENT ENOUGH TO PROMOTE SOME BETTER MIXING UP TO THE STRONGER
WINDS ROTATING AROUND THE DEPARTING LOW PRESSURE SYSTEM.
TEMPERATURES WILL BE COOLER BY 5 TO 8 DEGREES FOR MONDAY...BUT THIS
COOLER TREND LOOKS SHORT TERM AS TEMPERATURES SHOULD CONTINUE AN
UPWARD TREND THROUGH REMAINDER OF THE WEEK AS MODELS ARE SHOWING
BETTER CONSENSUS IN KEEPING THE NEXT TROF IN BACK ALONG THE LEFT
COAST WHILE HIGH PRESSURE BUILDS BACK WESTWARD FROM THE PLAINS.

&&

.AVIATION...

MECHANICAL TURBULENCE BECOMES WIDESPREAD THIS AFTERNOON THROUGH
EARLY EVENING WITH SUSTAINED WEST WIND OF 25 TO 35 KNOTS AND GUSTS AS
HIGH AS 45 KNOTS.  A COLD FRONT MOVES ACROSS NORTHWEST COLORADO
BETWEEN 21Z TO 03Z THIS EVENING AND EXPECT SCATTERED SHOWERS WITH
ISOLATED THUNDERSTORMS TO DEVELOP ALONG THE FRONT.  THIS FRONT SAGS
SOUTHWARD OVERNIGHT BUT SHOWERS WILL DISSIPATE.

STRONG WESTERLY FLOW WITH MECHANICAL TURBULENCE OVER THE HIGH
TERRAIN IS EXPECTED ON FRIDAY.

&&

.HYDROLOGY...
AREAL FLOOD ADVISORY CONTINUES FOR MOFFAT COUNTY THROUGH LATE THIS
WEEK AS RIVERS AND CREEKS CONTINUE TO FLOW NEAR OR JUST ABOVE BANKFUL
WITH THE POSSIBILITY FOR MINOR FLOODING. A FLOOD ADVISORY ALSO
REMAINS IN EFFECT FOR THE GREEN RIVER NEAR JENSEN DUE TO HIGH RIVER
FLOWS FROM SNOWMELT. WITH WARMER TEMPERATURES RETURNING...SNOWMELT
WILL AGAIN BE ACCELERATING...KEEPING THE RIVER RUNNING HIGH
THROUGH FRIDAY.
