AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
238 PM MDT TUE JUL 12 2005

.SHORT TERM...A FEW STORMS BEGINNING TO FIRE ALONG A BOUNDARY
EXTENDING FROM CENTRAL ELBERT COUNTY NORTHEAST TO SEDGWICK COUNTY.
WITH SURFACE BASED CAPES AROUND 1600 J/KG...AS NOTED BY LATEST LAPS
SURFACE DATA...BEST CHANCE FOR ADDITIONAL STORM DEVELOPMENT SHOULD
BE ALONG THE BOUNDARY.  PLATTEVILLE PROFILER SHOWING WEAK UPSLOPE
FLOW TO AROUND 700 MB...AND WITH SURFACE DEWPOINTS STILL HANGING IN
THE 50S ACROSS PLAINS...WILL KEEP SOME STORMS IN THE FORECAST THIS
EVENING. SEVERE POTENTIAL REMAINS LOW GIVEN MINIMAL VERTICAL WIND
SHEAR AND LACK OF UPPER DYNAMICS. A FEW STORMS ALONG THE BOUNDARY
COULD BRIEFLY APPROACH SEVERE LIMITS WITH WIND GUSTS THE MAIN
THREAT.  MAY BE SOME BRIEF HEAVY RAIN WITH THE STORMS AS THE LATEST
GPS INTEGRATED PRECIPITABLE WATER VALUES ARE HOVERING AROUND NINE
TENTHS OF AN INCH. GIVEN LACK OF UPPER SUPPORT...STORMS SHOULD BE
GONE BY MIDNIGHT.  ON WEDESDAY...UPPER LEVEL RIDGE CONTINUES TO
BUILD ALONG WEST SLOPE.  LOW LEVEL EASTERLY FLOW STILL PROGGED ACROSS
PLAINS...SHOULD MAINTAIN SURFACE DEWPOINTS IN THE 40S. FORECAST
SOUNDINGS SHOW SOME WARMING ALOFT ALONG WITH MID LEVEL DRYING. SO...
BARRING ANY SUBTLE BOUNDARIES HANGING AROUND... THUNDERSTORM CHANCES
LIMITED TO SOUTHERN FRINGES OF CWA...SPECIFICALLY FOOTHILLS OF
DOUGLAS AND SOUTHERN JEFFERSON COUNTIES...WHERE UPSLOPE SHOULD AID
IN DEVELOPMENT. AFTERNOON HIGHS SHOULD AGAIN REACH THE 90S ACROSS
THE PLAINS...THOUGH IT APPEARS THE HIGH OF 98 OFF THE NGM GUIDANCE
FOR DENVER APPEARS A BIT OVERDONE. STILL...WILL ADD A DEGREE OR TWO
TO THE TEMPERATURE GRIDS.

.LONG TERM...THE STRONG RIDGE ALOFT WILL BE BUILDING ACROSS WRN CO
WITH THE FLOW ALOFT FROM THE N-NE. AIRMASS WILL REMAIN CAPPED ACROSS
MOST LOCATIONS. THE ONLY EXCEPTION WOULD BE AROUND SUMMIT AND PARK
COUNTIES WHERE WILL KEEP ISOLD TS IN THOSE AREAS WITH JUST ENOUGH
MSTR/INSTABILITY TO POP A STORM. WILL KEEP EVERYONE ELSE DRY WED
NITE THRU THU. WILL MAINTAIN VERY LOW POPS FRI-SUN WITH VERY LITTLE
CHANGE IN THE OVERALL PATTERN.

LONG RANGE MODELS ARE STILL ADVERTISING A SIGNIFICANT UPPER LEVEL
TROF TO SWEEP ACROSS THE NRN PLAINS LATE SUN-MON TIME FRAME WITH
SIGNIFICANT COOLING AND BETTER CHANCES OF PRECIP ACROSS ERN CO.
ENSEMBLE MEMBERS ARE IN BETTER AGREEMENT TODAY AND OTHER
INTERNATIONAL PLAYERS ARE SIMILAR...THOUGH OPERATIONAL 00Z GFS IS
ONE OF THE MORE DEEPER AND COOLER SOLUTIONS. NOT READY TO GO WILD
WITH THIS YET...BUT WILL CONTINUE THE TREND OF LOWERING TEMPS AND
INCREASING POPS A BIT...ESP ON MONDAY.

.BOU...NONE.
