AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
220 AM MDT SAT JUN 25 2005

.SHORT TERM...QUITE A BIT OF MID LEVEL MOISTURE WILL CONTINUE TO
MOVE ACROSS THE AREA THRU TONIGHT IN SW FLOW ALOFT.  THIS MOISTURE
COMBINED WITH FAVORABLE LAPSE RATES WILL GENERATE SCT TSTMS IN MOST
AREA LATER THIS AFTN INTO EVENING HOURS.  SFC BASED CAPES WILL RANGE
FROM 1500 TO 2500 J/KG OVER NERN CO BY AFTN AND WITH FAVORABLE SHEAR
WILL LIKELY SEE A FEW SVR STORMS WITH LARGE HAIL BEING THE MAIN
THREAT.  MEANWHILE PRECIPITABLE WATER VALUES WILL BE AROUND AN INCH
SO COULD SEE SOME HEAVY RAINS AS WELL IN SOME LOCATIONS.  HI TEMPS
TODAY MAY BE A FEW DEGREES WARMER THAN YESTERDAY WITH READINGS
MAINLY IN THE MID 80S TO AROUND 90 ACROSS NERN CO.  FOR TONIGHT
TSTMS WILL LINGER OVER THE NERN PLAINS DURING THE EVENING HOURS BUT
SHOULD END AROUND MIDNIGHT.

.LONG TERM...ON SUNDAY...THE UPPER RIDGE WILL REMAIN OVER THE SRN
PLAINS WITH A UPPER TROF OVER THE WEST COAST.  THE END RESULT IS A
CONTINUED SWLY FLOW OVR COLORADO.  THE NAM HAS THE LOW LEVEL THETA-E
RIDGE ALONG THE KANSAS BORDER...WITH A SLY SFC WNDS IN THE AFTN.
THIS MAY STILL ALLOW FOR A CONTINUED CHC OF THE DENVER CYCLONE IN
THE AFTN.  FCST CAPES ON SUNDAY AFTN GENERALLY RANGE FROM 950-1300
J/KG...WITH A FAIRLY UNIFORM SWLY FLOW OVR THE AREA SO SHEAR MAY NOT
BE AS MUCH OF AN ISSUE.  ON MONDAY...THE FLOW ALOFT BECOMES A BIT
MORE WLY AS DOES THE WINDS AT THE SFC.  AS A RESULT THE POTENTIAL
FOR THUNDERSTORMS IN THE AFTN AND EVENING WILL LESSEN AS
WELL...ESPIECIALLY ALONG THE URBAN CORRIDOR.  THE LOW LEVEL THETA-E
RDG IS PROGGED TO BE ALONG THE ERN BORDER.  THIS WILL ALLOW FOR THE
BEST POTENTIAL FOR THUNDERSTORMS TO BE IN THE AREA DURING THE LATE
AFTN AND EVENING HOURS.  SLGT CHC ON MONDAY IN THE GRIDS LOOKS FINE
AT THIS POINT.  WILL LEAVE THE RMNDR OF THE FCST AS IS.

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

.DAY ONE...TODAY AND TONIGHT

SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP OVER
THE HIGH COUNTRY...THEN MOVE ACROSS THE URBAN CORRIDOR DURING THE
EARLY AFTERNOON AND SPREAD FURTHER EAST THEREAFTER.  A FEW STORMS
WILL LINGER INTO THE LATE NIGHT HOURS ON THE FAR NORTHEAST PLAINS.

THE THREAT OF SEVERE WEATHER IS A BIT HIGHER ON THE PLAINS TODAY
THAN YESTERDAY AS INSTABILITY...MOISTURE AND VERTICAL WIND SHEAR
HAVE ALL INCREASED FROM WHAT WAS AVAILABLE ON THURSDAY. LARGE HAIL
AND STRONG WIND GUSTS WILL BE THE MAIN THREATS. BRIEF HEAVY RAINS
ARE ALSO POSSIBLE WHICH COULD CREATE LOCALIZED FLOODING PROBLEMS.

WEAK UPSLOPE FLOW AT THE SURFACE AND A MINOR DISTURBANCE ALOFT WILL
CREATE THE FAVORABLE CONDITIONS FOR THE STRONG AFTERNOON CONVECTION.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

AFTERNOON AND EVENING THUNDERSTORMS WILL REMAIN IN THE FORECAST
THROUGH SUNDAY.  ENOUGH INSTABILITY AND WIND SHEAR WILL EXIST IN THE
ATMOSPHERE TO SUPPORT MORE SEVERE THUNDERSTORMS ACROSS THE FRONT
RANGE METRO AREAS AND EASTERN PLAINS...WITH LARGE HAIL AND HEAVY
RAINFALL BEING THE PRIMARY THREATS.

THE ATMOSPHERE IS THEN EXPECTED TO DRY SOMEWHAT EARLY NEXT WEEK.
THIS SHOULD REDUCE THE THREAT OF THUNDERSTORMS AND ANY SEVERE
WEATHER ESPECIALLY BY TUESDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON AND EVENING.
