AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
230 PM MDT FRI SEP 1 2006

...CORRECTION TO FIRST PARAGRAPH...

.SHORT TERM DISCUSSION...STRONG AUTUMN-LIKE COLD FRONT QUICKLY
MAKING ITS WAY SOUTH THROUGH NERN CO ATTM...WITH THE LEADING EDGE OF
UNSEASONABLY COOL BNDRY LAYER AIR SPILLING DOWN OFF THE CHEYENNE
RIDGE ON GUSTY N/NELY WINDS. HOWEVER EXTENSIVE BANK OF LOW CLOUDS
HAVE YET TO SPILL OVER THE RIDGE...BUT ONLY A MATTER OF TIME ONCE
SFC WINDS TURN MORE NELY. NEXT FEW HOURS BIGGEST CONCERN WILL BE THE
POTENTIAL FOR SVR T-STORMS IN HIGH CAPE AIR IN ELBERT...LINCOLN AND
SRN WASHINGTON COUNTIES. LATEST LAPS RUN INDICATES CAPE VALUES
UPWARDS OF 2000 J/KG CENTERED NEAR LIMON. SHOULD ALSO SEE THE
VERTICAL WIND SHEAR PROFILE IN THIS AREA BECOMING MORE FAVORABLE FOR
STRONG UPDRAFT FORMATION AS THE FRONT GETS CLOSER. DAMAGING HAIL
LOOKS TO BE MAIN SVR WX THREAT...BUT WOULDN/T RULE OUT A BRIEF
TORNADO AND LOCALLY HVY RAINFALL. POST-FRONTAL AIRMASS APXMTLY
5000-6000 FT DEEP...AND SO AREAS WEST OF THE CONT DVD SHOULD SEE
LITTLE IF ANY IMPACT FROM THIS FRONTAL SYSTEM. BY THIS EVENING...
NERN CO PLAINS INCLUDING THE I-25 URBAN CORRIDOR WILL PRETTY MUCH
BECOME SOCKED IN WITH LOW CLOUDS. COULD SEE CIGS IN THE DENVER METRO
AREA AS LOW AS A COUPLE HUNDRED FT AGL BY THIS EVENING. STORM
CHANCES SHOULD QUICKLY DIMINISH FM NORTH-TO-SOUTH AS THE COLD AIR
AND LOW CLOUDS MOVE IN. OVERNIGHT...SHOULD ALSO SEE PATCHY/AREAS OF
FOG FORMING ON THE PLAINS WITH LOWEST VSBYS IN LINCOLN AND ELBERT
COUNTIES WHERE LOW-LVL WINDS GRADUALLY BECOME SELY...WHICH WOULD
FAVOR ADVECTION FOG DVLPMNT.

ON SATURDAY...MODELS HANG ONTO LOW-LEVEL MOISTURE UP ALONG THE FRONT
RANGE DURING THE MORNING HRS WITH WEAK E-SELY UPSLOPE FLOW. CAN/T
ARGUE WITH THAT. THEREFORE WILL KEEP SCT-BROKEN LOW CLOUD COVERAGE
IN THIS AREA AT LEAST THROUGH MID-MORNING. OTHERWISE...COLD UPR LVL
TROUGH CURRENTLY PASSING OVER WY/NRN CO BARELY MOVES JUST EAST OF
THE AREA BY LATE AFTERNOON. HOWEVER DRIER MID-LVL AIR MOVING DOWN
WEST SIDE OF TROUGH SHOULD GO INTO CLEARING SKIES ON THE PLAINS BY
AFTERNOON. DAYTIME TEMPS SHOULD REMAIN UNSEASONABLY COOL WITH MAX
TEMPS EAST OF THE MTNS 10-15F BELOW NORMAL.

.LONG TERM DISCUSSION...SAT NGT-MON...MDLS BUILD UPR RDG OVR CNTRL
RCKYS THRU PRD.  THE AMS ACRS THE AREA WILL BCM DRY AND SUBSIDENT.
TEMPS WILL WARM TO ARND SEASONAL NORMS BY MON.  WILL GENLY FVR THE
WRMR GFS MOS TEMPS OVER THE MUCH COOLER ETA VALUES.

IN XTENDED PRD...TUE-FRI...MDLS MAINTAIN UPR RDG OVR WRN U.S. ALG
WITH PERSISTENT NWLY FLO ALF ACRS CNTRL RCKYS.  GFS IS SUGGESTIVE
OF A SLGT CHC OF PCPN DURING AFTNS AND EVES ON WED AND THU MAINLY
OVR MTNS IN ASSOC WITH WK SHT WV...SO WILL KEEP A MENTION OF THIS
IN FCST.  TEMPS WILL BE ARND SEASONAL NORMS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL
COLORADO.

.DAY ONE...TODAY AND TONIGHT

A STRONG COLD FRONT POISED JUST NORTH OF THE COLORADO STATE LINE
WILL DROP SOUTH THROUGH NORTHEAST COLORADO DURING THE AFTERNOON.
AHEAD OF THIS FRONTAL BOUNDARY...AMPLE SUNSHINE AND SURFACE
DEWPOINTS IN THE 50S WILL PRODUCE A FAVORABLE ENVIRONMENT FOR SHOWER
AND THUNDERSTORMS ON THE PLAINS THIS AFTERNOON. LOOK FOR SCATTERED
STORMS TO FORM AS THIS COLD FRONT MOVES SOUTH THROUGH THE AREA. A
FEW OF THESE STORMS MAY BECOME STRONG ENOUGH TO PRODUCE HAIL AND
BRIEF HEAVY RAIN. AFTER PASSAGE OF THE COLD FRONT WATCH FOR STEADILY
FALLING TEMPERATURES...WIDE SPREAD LOW CLOUDS AND SCATTERED LIGHT
RAIN SHOWERS FROM THE FRONT RANGE EASTWARD. AFTER MIDNIGHT PATCHY
FOG ON THE PLAINS MAY REDUCE VISIBILITIES TO LESS THAN A MILE AT
TIMES.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
