.DISCUSSION...
225 PM MDT THU JUL 22 2010

VISIBLE SATELLITE AND SURFACE ANALYSIS SHOWING A
TROUGH OVER THE MIDDLE OF THE FA AND THE FRONT OVER NORTHEAST
COLORADO. CU SHOWING UP NEAR THE SURFACE TROUGH OVER THE SOUTHEAST
FA. LATEST RADAR LOOP SHOWING A FEW THUNDERSTORMS OVER EASTERN
COLORADO WEST OF KIT CARSON/CHEYENNNE COUNTIES. WATER VAPOR IMAGERY
SHOWING TROPICAL MOISTURE STREAMING NORTH INTO COLORADO AND
NORTHEAST INTO NEBRASKA.

A SURFACE TROUGH AND THE H7 TROUGH AXIS WILL BE THE FOCUS FOR
THUNDERSTORM DEVELOPMENT AND HIGHER POPS THROUGH THIS FORECAST. THE
SURFACE TROUGH IS PROGGED TO MOVE SOUTHEAST SO WILL ADD HIGHER POPS
TO THE SOUTHEAST ZONES THIS EVENING AND ALONG THE FRONT OVER THE
NORTHWEST AND AT LEAST CHANCE POPS ELSEWHERE ACROSS THE MID PORTION
OF THE FA. THE H7 TROUGH AXIS SHOULD BE MOSTLY STATIONARY ACROSS THE
NORTHWEST BUT THE SURFACE TROUGH WILL MOVE BACK NORTHWEST OVERNIGHT
WITH ONLY A SLIGHT CHANCE OF THUNDERSTORM DEVELOPMENT ALONG THAT
AXIS AFTER 06Z FRI.

STORM MOVEMENT TONIGHT WILL BE SLOW (5-10KTS) AND PRECIPITABLE WATER
IS 150 PERCENT OF NORMAL. PLAN TO INCLUDE LOCALLY HEAVY RAINFALL
POSSIBLE.

THE SURFACE TROUGH WILL FOCUS CONVECTION ON FRIDAY AND WILL BE IN A
POSITION FOR CHANCE POPS ACROSS THE ENTIRE FA. BY FRIDAY EVENING THE
SURFACE TROUGH IS EXPECTED TO BE OVER THE SOUTHEAST ZONES WHERE
THERE WILL BE CHANCE POPS AND SLIGHT CHANCE POPS NORTHWEST OF THAT
AXIS. AFTER 06Z SATURDAY MOST OF THE DYNAMICS SHOULD BE SOUTHEAST OF
THE FA SO WILL ONLY HAVE SLIGHT CHANCE POPS OVER THE SOUTHEAST.
SUBSIDENCE IS OVER THE FA SATURDAY MORNING. BY SATURDAY
AFTERNOON/EVENING THE TROUGH WILL BE CLOSE ENOUGH TO WARRANT AT
LEAST SLIGHT CHANCE POPS OVER THE SOUTHEAST ZONES.

HIGH PRESSURE/SUBSIDENCE WILL BE OVER THE FA BUT UPSLOPE WILL
PROVIDE SOME CONVERGENCE OVER HIGHER TERRAIN IN COLORADO SO CANNOT
RULE OUT A SLIGHT CHANCE OF STORMS OVER THE EASTERN COLORADO ZONES
SUNDAY AFTERNOON. A FEW OF THESE STORMS COULD DRIFT EAST INTO
NORTHWEST KANSAS BUT AM NOT OVERLY CONFIDENT OF THAT SO WILL GO
ALONG WITH A SLIGHT CHANCE FOR THE FA FOR THE EVENING PERIOD AS WELL.

MAX TEMPERATURE GUIDANCE HAS BEEN TOO WARM IN THE VICINITY OF THE
TROUGH SO HAVE LOWERED GUIDANCE SOME FOR FRIDAY. OTHERWISE 850
TEMPERATURES INDICATE TEMPERATURES SHOULD RISE INTO THE 90S WITH
WARMEST READINGS OVER THE SOUTHEAST AND COOLEST TEMPERATURES IN THE
NORTHWEST. 850 TEMPERATURES COOL ON SATURDAY/SUNDAY SO EXPECT MAX
READINGS IN THE MID 80S. MIN TEMPERATURES WILL BE IN THE LOWER TO
MID 60S WITH COOLER READINGS SATURDAY NIGHT/SUNDAY NIGHT. GUIDANCE
ACTUALLY TAKES MINS DOWN TO THE UPPER 50S IN THE WEST SATURDAY NIGHT.

IN THE EXTENDED...A RIDGE WILL BE OVER THE ROCKIES/PLAINS THROUGH
THE PERIOD. UPSLOPE CONDITIONS WILL FAVOR STORMS OVER THE HIGHER
TERRAIN IN EASTERN COLORADO MONDAY AFTERNOON. SUBSIDENCE TAKES OVER
MONDAY NIGHT THROUGH TUESDAY. A COUPLE OF SHORTWAVES RIDE OVER THE
RIDGE AND HAVE A SLIGHT CHANCE OF PRODUCING THUNDERSTORMS
WEDNESDAY/THURSDAY. MAX TEMPERATURES WILL RISE INTO THE LOWER/MID
90S. MIN TEMPERATURES WILL RANGE FROM THE LOWER 60S WEST TO THE
UPPER 60S/NEAR 70 EAST.

.AVIATION...
1114 AM MDT THU JUL 22 2010

FOR THE 18Z TAFS...VFR EXPECTED THROUGH MID AFTERNOON...BUT
INCREASING THUNDERSTORM CHANCES BY LATE THIS AFTERNOON AND THIS
EVENING COULD IMPACT AVIATION OPERATIONS AT EITHER KGLD OR KMCK.
SATELLITE IMAGERY SHOWS SOME COOLING CLOUD TOPS ACROSS THE
REGION...NEAR WHAT APPEARS TO BE THE TRUE COLD FRONT. ANOTHER
BOUNDARY FURTHER SOUTH MAY BE THE OLD PRE FRONTAL TROUGH.
NONETHELESS...BOTH WILL BE THE FOCUS FOR RENEWED CONVECTION WITH
DAYTIME HEATING. STORM MOTIONS WILL HAVE A SIGNIFICANT EASTERLY
COMPONENT...BRINGING THEM TOWARDS BOTH TERMINALS. THE THREAT FOR
HAIL OR STRONG WINDS IS A BIT HIGHER AT KMCK DUE TO BETTER
INSTABILITY AND WIND SHEAR...THOUGH CANNOT BE RULED OUT AT KGLD
EITHER.
