AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
1032 AM MDT MON MAY 21 2012
.SHORT TERM...(TODAY THROUGH WEDNESDAY)
ISSUED AT 255 AM MDT MON MAY 21 2012
HGT RISES ALREADY OCCURRING THIS MORNING AND WILL CONTINUE
THROUGH THE DAY AS WEAK RIDGING BUILDS IN FROM THE WEST. THERE
WILL BE PLENTY OF SUN AND WARM TEMPS TODAY. HOWEVER...MODELS DO
SHOW SOME MOISTURE WORKING ITS WAY OVER CONTINENTAL
DIVIDE...ESPECIALLY SAN JUANS...WHERE FAVORABLE WIND FLOW WILL
CAUSE SOME VERY ISOLATED SHOWERS AND TSTORMS TO FORM LATER THIS
AFTN. ANTICIPATE ANY STORMS THAT FORM WILL QUICKLY PULSE UP AND
DOWN WITH MAIN CONCERN BEING SOME GUSTY SFC WINDS DUE TO OUTFLOW
FROM SAID STORMS.
BY MONDAY NIGHT THE RIDGE SHIFTS ONTO THE EASTERN PLAINS. A WEAK
BUT DRY DISTURBANCE WILL THEN PASS OVER THE SOUTHERN ZONES
TOWARDS MORNING THAT WILL INCREASE THE SW GRADIENT WINDS AND
WEAKEN NOCTURNAL INVERSIONS AND THEREFORE RAISE MIN TEMPERATURES UP A
BIT. NO SHOWERS ARE EXPECTED WITH THIS WAVE.
ON TUESDAY THE TROUGH WORKS THROUGH THE NORTHERN ROCKIES AS THE
COLD FRONT MOVES INTO CENTRAL UTAH IN THE AFTERNOON. STRENGTHENING
SW FLOW WILL CAUSE THE SOUTHERN AND CENTRAL ZONES TO RECEIVE
PLENTY OF WARM ADVECTION. A DRY SW FLOW WILL RAISE TEMPS AND
LOWER DEWPOINTS FOR VERY DRY AFTERNOON CONDITIONS. WIND GUSTS UP
TO 40 MPH ARE ALSO POSSIBLE ACROSS THE NORTH WHILE THE SOUTH WILL
SEE WIND GUSTS CLOSE TO THE FIRE CRITICAL 25 MPH.
BY TUESDAY NIGHT THE INITIAL COOL FRONT WORKS THROUGH THE NORTH
AND BECOMES W-E ORIENTED NEAR THE I-70 CORRIDOR BY MORNING. THE
00Z MODEL RUNS HAVE BACKED OFF ON QPF WITH THIS FRONT WITH ONLY
ISOLATED SHOWERS POSSIBLE ALONG THE WYOMING BORDER.
ON WEDNESDAY A SECOND DISTURBANCE DIGS DOWN THE BACK OF THE
DEVELOPING WESTERN TROUGH. THE INITIAL FRONT WILL REMAIN STATIONARY
NEAR I-70 THROUGH THE DAY WHILE A STRONGER FRONT WORKS THROUGH
UTAH. MOISTURE AND INSTABILITY WILL INCREASE OVER THE COLORADO
NORTHERN-CENTRAL MTNS THROUGH THE AFTERNOON FOR SCATTERED MAINLY
MOUNTAIN SHOWERS AND STORMS. WINDS DIMINISH IN THE COOLER AIR MASS
NORTH OF I-70...WHILE DRY AND WARM SW FLOW CONTINUES NEAR THE FOUR
CORNERS.
.LONG TERM...(WEDNESDAY NIGHT THROUGH SUNDAY NIGHT)
ISSUED AT 255 AM MDT MON MAY 21 2012
MODELS AGREE THAT A MORE WELL-DEFINED COLD FRONT WILL BE DROPPING
DOWN ACROSS THE REGION WED NIGHT INTO THUR MORNING AS AN ASSOD VERTICALLY-
STACKED AREA OF LOW PRESSURE MOVES EWRD ALONG US/CANADIAN BORDER. GOOD
UPPER LEVEL SUPPORT WILL ALSO AID FROPA AS POCKETS OF ENERGY MOVE
THRU THE LONG-WAVE PATTERN DIRECTLY OVER UT AND CO. EXPECT
SHOWERS/STORMS FOR NERN UT/NWRN CO WED NIGHT SPREADING SEWRD
OVERNIGHT WITH UNSETTLED WX AND PLENTY OF CLOUDS CONTINUING
THROUGH THURSDAY AS EMBEDDED DISTURBANCES CONTINUE TO STREAM
ACROSS THE AREA. H7 TEMPS WILL DROP APPROX 10 DEG BEHIND FRONT BY
THUR AFTN SO A SIGNIFICANT DROP IN SFC HIGH TEMPS IS EXPECTED AS
AMPLE CLOUD COVER AND COLD AIR ADVECTION KEEP TEMPS BELOW
CLIMATOLOGY.
PROGRESSIVE WX PATTERN CONTINUES AS ANOTHER AREA OF LOW PRESSURE
FORMS OFF PAC NW COAST EARLY FRIDAY MORNING AND DROPS DOWN INTO
GREAT BASIN BEFORE MOVING NEWRD EARLY SATURDAY. BOTH GFS40 AND
EUROPEAN HIGHLIGHT SOME PRECIP OVER CWA BUT KEEP BULK OF PRECIP
TO THE NW AND N. BLENDED GUIDANCE IS BITING OFF ON SOLN SO
MINIMAL POPS IN FORECAST ATTM. A FEW MORE MODEL RUNS WILL
INCREASE CONFIDENCE IN KEEPING POPS DOWN. GETTING BACK TO AREA OF
LOW PRESSURE...ONCE IT REACHES GREAT BASIN...PRESSURE GRADIENT
WILL TIGHTEN CONSIDERABLY FRIDAY EVENING THROUGH LATE SATURDAY
NIGHT WITH 700MB WINDS OF 35 TO 50 KTS OVER WRN AREAS OF CO AND
EASETERN AREAS OF UT. GOOD MIXING SHOULD ALLOW STRONG SFC WINDS
WITH GUSTS REACHING THESE VALUES.
BY SUNDAY...LOW PRESSURE WILL BE JUST ENTERING CANADA WHILE A WEAK
POST-FRONTAL TROUGH WILL MOVE ACROSS CWA BUT WITH LITTLE MOISTURE
TO WORK WITH...EXPECT A FEW SHOWERS AND NOT MUCH ELSE.
AFTER FROPA ON THURSDAY...TEMPS WILL QUICKLY REBOUND TO SEASONAL
NORMS.

.FIRE WEATHER...
ISSUED AT 320 PM MDT SUN MAY 20 2012
TUESDAY...ALL OF COLORADO WILL BE IN A PRE-FRONTAL WARM AND DRY
SOUTHWEST FLOW. 10000 FOOT WINDS INCREASE TO 40 MPH ACROSS NW
COLORADO BUT ONLY TO 25 MPH SOUTH. THERE IS STILL SOME UNCERTAINTY
ABOUT REACHING CRITICAL 25 MPH GUSTS NEAR THE FOUR CORNERS TUESDAY
AFTERNOON. DRY CONDITIONS ARE MORE CERTAIN FOR ALL ZONES. THE PRE-
FRONTAL AIR MASS WILL INCREASE TEMPERATURES BUT ALSO LOWER
DEWPOINTS FOR WIDESPREAD RH VALUES WELL BELOW 15%. THE COLD FRONT
WORKS TO THE I-70 CORRIDOR OVERNIGHT.
WEDNESDAY...COLORADO ZONE 207 REMAINS SOUTH OF THE COLD FRONT
THROUGH THE DAY. DRY AND GUSTY CONDITIONS WILL CONTINUE THERE SO
HAVE ISSUED A FIRE WEATHER WATCH FOR WEDNESDAY AFTERNOON. ZONES
290-292-293 MAY ALSO BE NEAR CRITICAL FIRE CONDITIONS WEDNESDAY
AFTERNOON IF THE SECOND COLDER FRONT SLOWS DOWN. FURTHER NORTH...
LESS WIND...COOLER AND MOISTER CONDITIONS WILL BRING FIRE RELIEF.
THURSDAY-SUNDAY...PACIFIC ENERGY WILL THEN CONTINUE TO CARVE OUT
A LOW PRESSURE TROUGH ALONG THE WEST COAST THROUGH THE REMAINDER
OF THE PERIOD. THIS WILL RESULT IN BREEZY CONDITIONS EACH
AFTERNOON. IN ADDITION AFTER COOLER TEMPERATURES ON THURSDAY...A
WARMING TREND IS EXPECTED FOR THE END OF THE WEEK.
