AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
235 PM MDT SUN JUN 19 2005

.SHORT TERM...CONVECTIVE TEMPERATURES HAVE BEEN REALIZED AS
EVIDENCED BY THE CUMULUS CLDS DVLPG.  NEARLY ALL OF THESE ARE IN THE
FOOTHILLS WITH THE EXCEPTION OF ONE CELL IN CROWLEY COUNTY WHICH HAS
TAKEN ADVANTAGE OF AN OLD BOUNDRY TO GET GOING.  DWPTS ACRS THE
PLAINS ARE QUITE HIGH FOR THIS CWFA WITH MAY LOCATIONS EAST OF
DENVER RPTG READINGS OVER 60.  THIS IS BEING WASTED FOR THE MOST
PART THOUGH... STG INVERSIONS WILL KEEP A DAMPER ON TSTMS THIS
EVENING.  BUT WITH STG ELEVATED HEATING SOME ISOLD POPS ARE
WARRANTED ON THE FNT RANGE AND HIGH COUNTRY EAST OF THE DIVIDE THIS
EVENING.

TMRW LOOKS LIKE ANOTHER CORKER WITH LWR TO MID 90S XPCTD ON THE
PLAINS.  TEMPS WL PBLY BE 5 DEGREES OR SO WARMER ON THE FNT RANGE AS
THERE WONT BE ANY DENVER CYCLONE TO SUPRESS HEATING MONDAY UNLIKE
TODAY.  HIER RESOLUTION ETA INDG A WEAK SHORTWAVE WILL TUMBLE ACRS
THE TOP OF THE RDG TMRW EVENING. THIS SHOULD RESULT IN A MODEST
UPSWING IN CONVECTION ACRS THE AREA.  WL ADD ISOLD POPS TO THE
PLAINS AS STORMS MAY CLIP THE NORTHEAST CORNER OF THE STATE IF AN
MCS FORMS IN SD OR NEBR.

.LONG TERM...BIG RIDGE ALOFT WILL BE WITH US FOR MUCH OF NEXT WEEK
BUT ALREADY THERE HAS BEEN SOME MSTR SEEPAGE INTO THE STATE. WATER
VAPOR IMAGERY ALREADY SHOWS HIGHER MSTR VALUES STREAMING NORTHWARD
FROM MEXICO AND GFS/NAM ARE PICKING UP ON THIS AND ROTATING THE MSTR
INTO CO DURING THE NEXT FEW DAYS. MODEL GRIDDED FIELDS INDICATE
ENOUGH MOISTURE AND INSTABILITY TO GENERATE ISOLD STORMS IN THE LATE
AFTN/EVENING HOURS. AREAL COVERAGE WILL BE VERY HARD TO PREDICT FROM
DAY TO DAY SO WILL BLANKET ISOLD POPS IN MOST LOCATIONS THRU THE
REST OF WEEK. BEST CHANCES WILL STILL BE OVER THE MOUNTAINS AND
HIGHER TERRAIN LOCATIONS. TEMPS WILL REMAIN IN THE 90S ACROSS MUCH
OF ERN CO...BUT A BIT OF COOL DOWN LATER IN THE WEEK AS THE MAIN
CENTER OF THE HIGH IS SUPPRESSED AND HEIGHTS BEGIN TO FALL A BIT.

.BOU...NONE.

What these are

Hail: Hail three-quarters of an inch or larger, or smaller hail that caused damage, filed with the largest stone measured.
Flash Flood: Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.
