AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
306 AM MDT THU JUN 26 2014

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 303 AM MDT THU JUN 26 2014

LATEST IR IMAGERY SHOWS THE PACIFIC TROUGH OVER NV AND WRN UT THIS
MORNING AS IT SLOWLY TRACKS EAST. NOT MUCH CHANGE TO FORECAST
THINKING AS THE TROUGH AND ASSOD COLD FRONT START TO MOVE OVER THE
AREA WITH THE UPPER LEVEL SUPPORT OUTRUNNING THE SFC FRONT AS IT
GETS HUNG UP ON THE MTNS OF UT. DESPITE SOME LOW TO MID LEVEL
INSTABILITY THIS AFTN...NAM/EC/GFS/HRRR NOT REALLY PICKING UP ON
VERY WIDESPREAD SHOWERS OR STORMS DUE TO CONTINUED DRY ATMOSPHERE
IN PLACE. THAT'S NOT TO SAY THERE WON'T BE STORMS...THERE WILL
BE...BUT A NEGATIVELY TILTED SYSTEM USUALLY PRODUCES
STRONGER...MORE PRONOUNCED STORMS WHILE THIS DOESN'T LOOK TO BE
THE CASE TODAY. AS HAS BEEN THE CASE ALL WEEK...STORMS WILL HAVE
GUSTY OUTFLOW WINDS OF 40 TO 45 MPH. ASIDE FROM PRECIP...WINDS
WILL INCREASE TODAY REACHING 25 TO 30 MPH KEEPING FIRE WX CONCERNS
AT THE FOREFRONT OF ISSUES TODAY. ANY STORMS THAT DO FORM IN
AREAS WHERE THE GRADIENT HAS TIGHTENED MAY LEND THEMSELVES TO
GUSTS OVER 50 MPH THIS AFTN AND EVENING. AGAIN...STORMS WILL BE
ISOLATED TO SOMEWHAT SCATTERED IN NATURE SO THESE STRONGER WINDS
WILL OCCUR FOR A VERY SMALL PORTION OF THE CWA. STRONGER SFC WINDS
SHOULD KEEP HIGH TEMPS DOWN A BIT TODAY BEFORE THE COLD FRONT
MOVES THROUGH TOMORROW.

THE UPPER LEVEL TROUGH AND ITS ASSOCIATED COLD FRONT WILL TREK EASTWARD
ACROSS THE CWA OVERNIGHT AND INTO FRIDAY MORNING. SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS WILL CONTINUE OVERNIGHT WITH
GUSTY WINDS AS THE BIGGEST THREAT. THOUGH CAPE VALUES ARE
LOW...DIVERGENCE ALOFT WITH COLD AIR FILTERING IN FROM THE
NORTHWEST WILL HELP TO KEEP SHOWERS GOING THROUGH THE NIGHT.

ON FRIDAY...WITH A NEGATIVELY TILTED TROUGH ALOFT...COOLER
TEMPERATURES ALOFT AND THE ADDED DAYTIME HEATING FACTOR...LAPSE
RATES WILL BE MODERATELY STEEP AND PRIMED FOR SCATTERED TO
NUMEROUS SHOWERS AND THUNDERSTORMS ACROSS THE REGION. PWAT VALUES
DO INCREASE TO 0.5 TO 0.6 INCH ON FRIDAY SO INCREASED POPS UP
FROM PREVIOUS FORECAST. COOLER NORTHWESTERLY FLOW AND CONVECTION
ON FRIDAY WILL ALLOW TEMPERATURES TO REMAIN ABOUT 5 DEGREES BELOW
NORMAL FOR THE DAY. STORM COVERAGE WILL DWINDLE IN THE EVENING AS
SUBSIDENCE BEHIND THE TROUGH SUPPRESSES CONVECTIVE DEVELOPMENT.

.LONG TERM...(FRIDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 303 AM MDT THU JUN 26 2014

ON SATURDAY...TEMPERATURES WILL REBOUND SLIGHTLY AS WINDS SHIFT
FROM NORTHWEST TO WESTERLY THROUGHOUT THE DAY...BUT WILL STILL
REMAIN AT OR BELOW NORMAL

ZONAL FLOW SETS UP SUNDAY AND BECOMES SWLY BY MIDWEEK AS A LARGE
AREA OF HIGH PRESSURE SETS UP OVER THE GREAT BASIN. SMALL PIECES
OF ENERGY WILL MAKE IT UNDER THE RIDGE FROM TIME TO TIME ALLOWING
SOME AFTN/EVENING CONVECTION FROM MONDAY ONWARDS. THESE STORMS
WILL BE SHORT-LIVED AS THE HIGH PRESSURE WILL LIMIT UPPER LEVEL
SUPPORT AS WELL AS ANY VERTICAL DEVELOPMENT.  TEMPS WILL BE
RUNNING WARM THROUGH THE PERIOD.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z FRIDAY MORNING)
ISSUED AT 303 AM MDT THU JUN 26 2014

EXPECT VFR CONDITIONS TO BE PREDOMINANT TODAY EVEN WITH A TROUGH
AND FRONT APPROACHING. CONDITIONS WILL DETERIORATE FROM 18Z
ONWARDS WITH SOME ISOLD SHOWERS/TSRA FORMING THOUGH NONE EXPECTED
OVER TAF SITES. HIGHER TERRAIN WILL BE FAVORED FOR PRECIP ESPECIALLY
NERN UT AND NRN CO. WINDS WILL ALSO BE GUSTY WITH SFC WINDS REACHING
25 TO 30 MPH. OUTFLOW FROM STORMS COULD REACH 45 MPH AND MIXING
WITH SFC WINDS COULD CAUSE AN INCREASE OF WINDS TO GREATER THAN 50
MPH. SOME SHOWERS AND STORMS WILL POSSIBLY OCCUR INTO THE
OVERNIGHT.

&&

.FIRE WEATHER...
ISSUED AT 303 AM MDT THU JUN 26 2014

RED FLAG WARNINGS CONTINUE AND REMAIN IN EFFECT FROM NOON TO 9PM
TODAY. GUSTY SURFACE WINDS OF 25 TO 30 MPH WILL BE COMMON ESPECIALLY
OVER WESTERN SECTIONS OF CO AND EASTERN UT. AN IMPORTANT NOTE IS
THAT ANY STORMS OR SHOWERS THAT FORM MAY PRODUCE OUTFLOW WINDS OF
40 TO 45 MPH. THESE WINDS COULD COMBINE WITH THE SURFACE WINDS
PRODUCING GUSTY WINDS OF 50 MPH OR GREATER UNDER THE STRONGER
SHOWERS AND STORMS. ANOTHER CONCERN WILL BE DRY LIGHTNING FROM ANY
STORMS THAT FIRE THIS AFTERNOON AND EVENING.  WINDS SHOULD START
DYING DOWN AFTER SUNSET AND WITH THE COLD FRONT COOLING THINGS
DOWN...FIRE WEATHER CONCERNS WILL DIMINISH BY FRIDAY.
