AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
254 AM MDT THU AUG 26 2010

.SHORT TERM...UPPER LEVEL RIDGE WILL REMAIN CENTERED OVER THE
CENTRAL ROCKIES TODAY. JUST LIKE YESTERDAY AIRMASS WILL BE VERY WARM
AND DRY. TEMPERATURES WILL INCREASE ABOUT 3-6F TODAY PUTTING MOST
LOCATIONS IN THE UPPER 80S TO MID 90S. MODELS SHOWING LITTLE TO NO
CAPE OVER THE HIGHER TERRAIN TODAY...PLUS MOISTURE IS EVEN A LITTLE
LESS THAN YESTERDAY. DID NOT HAVE ANY SHOWERS OR THUNDERSTORMS OVER
THE FORECAST AREA YESTERDAY. SINCE MOISTURE AND INSTABILITY
DECREASES TODAY...WILL NOT HAVE ANY POPS IN THE FORECAST THROUGH
TONIGHT. DO EXPECT SOME FLAT CUMULUS CLOUDS OVER THE HIGHER TERRAIN
AND THAT WILL BE IT FOR CLOUDS.

THE RIDGE WILL BEGIN TO SHIFT EAST TONIGHT AS AN UPPER LEVEL TROUGH
MOVES OVER THE PACIFIC NORTHWEST. NORMAL DIURNAL WINDS AND CLEAR
SKIES WILL PREVAIL TONIGHT AS THE RIDGE WILL CONTINUE TO DOMINATE
THE WEATHER.

.LONG TERM...AN UPPER LEVEL TROUGH WILL DEVELOP OVER THE WRN US FM
FRI INTO SAT WITH SWLY FLOW ALOFT AS AN UPPER LEVEL RIDGE FORMS OVER
THE ERN US.  SOME SUBTROPICAL MOISTURE WILL ADVECT IN FM THE SWRN US
ESPECIALLY BY SAT.  APPEARS THERE WILL BE ENOUGH MOISTURE AROUND FOR
SOME ISOLD TO WDLY SCT HIGH BASED TSTMS IN THE MTNS LATE FRI
AFTN/EVENING.  OVER NERN CO IT LOOKS DRY WITH HIGHS WELL ABOVE
NORMAL ON FRI WITH READINGS IN THE 90S.  THERE IS SOME THREAT FOR
FIRE DANGER OVER THE FAR NERN PLAINS IN THE 21Z-03Z TIME FRAME BASED
ON BNDRY LAYER WINDS AND HUMIDITIES.  ON SAT THERE WILL BE A BETTER
CHC FOR SCT TSTMS IN THE MTNS AS DEEPER SUBTROPICAL MOISTURE ADVECTS
INTO THE AREA IN SW FLOW ALOFT WITH A SLIGHT CHC OF TSTMS OVER THE
PLAINS.  HIGHS ON SAT OVER NERN CO WILL BE A FEW DEGREES COOLER BUT
STILL REMAIN ABOVE NORMAL.

FOR SUN THE MAIN UPPER LEVEL TROUGH WILL STILL REMAIN TO THE WEST OF
COLORADO WITH SWLY FLOW ALOFT.  SUBTROPICAL MOISTURE IS FCST TO
DECREASE BY LATEST GFS WHICH MAY REDUCE TSTM CHANCES IN THE MTNS IF
IT DOES OCCUR.  OTHERWISE WILL CONTINUE WITH A SLIGHT CHC OF TSTMS
OVER THE REST OF THE AREA.  HIGHS ON SUN WILL WRM BACK INTO THE
LOWER TO MID 90S ACROSS NERN CO BASED ON LATE 850-700 MB TEMPS.   BY
MON THE MAIN UPPER LEVEL TROUGH WILL WEAKEN AND MOVE INTO THE NRN
ROCKIES WITH MAINLY DRY WSW FLOW ALOFT OVER NRN CO ALONG WITH BEING
ON THE SUBSIDENT SIDE OF THE JET.  THUS IT LOOKS TO ME THAT ANY TSTM
ACTIVITY WILL BE IN THE ISOLD TO WDLY SCT CATEGORY BASED ON CURRENT
TRENDS.  HIGHS ON MON ONCE AGAIN MAY REACH THE LOWER TO MID 90S
ACROSS NERN CO AS 850-700 MB TEMPS ARE THE SAME AS SUN.

BY TUE DRY WLY FLOW ALOFT WILL BE OVER NRN CO AS A FLAT UPPER LEVEL
RIDGE DEVELOPS.  A WEAK FNT WILL MOVE INTO NERN CO ON TUE AND BRING
SOME COOLER AIR TO AREAS EAST OF THE MTNS WITH READINGS DROPPING
BACK TO NR SEASONAL LEVELS.  INITIAL LOW LEVEL MOISTURE WITH THIS
FNT IS LACKING TSTM CHANCES LOOK RATHER LOW.  FOR WED WEAK WSW FLOW
ALOFT WILL BE OVER THE AREA WITH AN INCREASE IN LOW LEVEL MOISTURE
OVER THE NERN PLAINS WHICH MAY LEAD TO A BETTER CHC OF TSTMS.  IN
THE MTNS IT LOOKS DRY BOTH DAYS.

.AVIATION...TYPICAL SOUTH TO SOUTHWEST DRAINAGE WINDS WILL PREVAIL
THROUGH 15Z AND THEN BECOME LIGHT AS THEY SHIFT TO THE EAST AFTER
18Z. UPPER LEVEL RIDGE OVER THE REGION WILL KEEP SKIES CLEAR FOR THE
NEXT 24 HOURS.

.BOU WATCHES/WARNINGS/ADVISORIES...NONE.
