.UPDATE...
ISSUED AT 752 PM MDT FRI JUL 6 2012
EXPIRED RED FLAG WARNING.
THUNDERSTORMS HAVE FOR THE MOST PART MOVED OUT OF THE FORECAST
AREA. CANNOT RULE OUT ADDITIONAL DEVELOPMENT WITH SEVERAL
MESOSCALE BOUNDARIES IN THE AREA...BUT SHOULD BE ISOLATED WITH
LOSS OF DAYTIME HEATING AND BOUNDARY LAYER COOLING.

.SHORT TERM...(TONIGHT THROUGH SATURDAY)
ISSUED AT 225 PM MDT FRI JUL 6 2012
LATEST SATELLITE AND RADAR IMAGERY DEPICTS A PRE-FRONTAL TROUGH OVER
THE NORTHWEST PART OF THE AREA BETWEEN ST. FRANCIS AND WRAY
STRETCHING SOUTHWEST TO NORTHEAST WITH A COLD FRONT OVER NEBRASKA
ROUGHLY FROM SIDNEY NORTHEAST TO AINSWORTH. SURFACE OBSERVATIONS
INDICATE HIGHER DEW POINT'S BEHIND THE COLD FRONT...WHICH WILL HELP
INCREASE INSTABILITY ONCE THE COLD FRONT MOVES INTO THE AREA THIS
EVENING.
EARLY THIS EVENING A COLD FRONT WILL MOVE INTO THE AREA AND MERGE WITH
THE SURFACE TROUGH THAT HAS BEEN OVER THE NORTHWEST PART OF THE AREA
TODAY. THE BEST MOISTURE...INSTABILITY...AND LIFT WILL BE ALONG AND
NORTH OF THE FRONT DURING THE EVENING. AS SUCH HAVE PRECIP. CHANCES
HIGHEST DURING THIS TIMEFRAME. WITH STORM MOTIONS ALMOST DUE
NORTH...STORM ACTIVITY WILL BE CLOSELY TIED TO THE FRONT. HEAVY
RAINFALL AND STRONG TO SEVERE WIND GUSTS WILL BE THE PRIMARY HAZARDS
WITH THESE STORMS. AS THE NIGHT PROGRESSES THE FRONT MOVES FURTHER
SOUTH. MODELS DISAGREE HOW FAR SOUTH THE FRONT WILL MOVE DURING THE
NIGHT...BUT GENERALLY PLACE THE FRONT FROM KIT CARSON NORTHEAST TO
MCCOOK DURING THE OVERNIGHT HOURS. AS THE FRONT MOVES FURTHER SOUTH
IT MOVES AWAY FROM THE BETTER INSTABILITY...WHICH WILL REMAIN OVER
THE YUMA COUNTY AREA. AS A RESULT PRECIP. CHANCES WILL COME TO AN
END DURING THE OVERNIGHT HOURS AS THE ENVIRONMENT BECOMES MORE
STABLE AND DRIER THE FURTHER SOUTH THE FRONT MOVES.
RAPID PRESSURE RISES BEHIND THE COLD FRONT WILL CAUSE WINDS TO BE
GUSTY THIS EVENING. DURING THE OVERNIGHT HOURS THE PRESSURE RISES ARE NOT
AS RAPID SO THE WIND GUSTS WILL NOT BE AS STRONG.
SATURDAY THE FRONT CONTINUES TO MOVE THROUGH THE AREA DURING THE
MORNING...THEN STALLS JUST SOUTH OF THE TRI-STATE AREA DURING THE
AFTERNOON. MID LEVEL LIFT AND CAPE INCREASE DURING THE AFTERNOON
ALONG AND NORTH OF THE FRONT. DURING THE LATTER HALF OF THE
AFTERNOON AN UPPER LEVEL SHORT WAVE TROUGH MOVES OVER EASTERN
COLORADO. HAVE PRECIP. CHANCES EXPANDING NORTHWARD OVER EASTERN
COLORADO DURING THE LATTER HALF OF THE AFTERNOON AS THE UPPER LEVEL
TROUGH MOVES THROUGH. HOWEVER THE BEST CHANCES FOR PRECIP. WILL BE
NORTH OF THE FRONT FROM WILD HORSE EAST TO TRIBUNE AND LEOTI.
PRECIP. CHANCES THEN DECLINE TO THE NORTH AS LIFTING DECAYS FURTHER
FROM THE FRONT. STORM MOTIONS WILL BE NEARLY STATIONARY...SO ANY
PRECIP. ACTIVITY WILL BE CLOSELY TIED TO THE FRONT AND MID LEVEL
LIFT. HEAVY RAINFALL AND STRONG TO SEVERE WIND GUSTS WILL BE THE
PRIMARY THREATS WITH ANY STORMS THAT DEVELOP.
.LONG TERM...(SUNDAY THROUGH FRIDAY)
ISSUED AT 225 PM MDT FRI JUL 6 2012

INITIALLY PLAN TO KEEP POPS LOW SATURDAY EVENING WITH THE FRONT WELL
TO THE SOUTH AND THE NEXT SHORTWAVE STILL APPROACHING. ALSO FORECAST
SOUNDINGS SHOW MOISTURE STILL NOT IDEAL. POPS WILL INCREASE FROM
WEST TO EAST AFTER 06Z SUNDAY AS DYNAMICS FROM THE SHORTWAVE AFFECT
THE FA. THERE WILL BE A LULL IN ACTIVITY SUNDAY MORNING SO HIGHER
POPS WILL REVERT BACK TO FRONTAL PROXIMITY. POPS WILL INCREASE
SUNDAY AFTERNOON AND SUNDAY NIGHT AS THE NEXT SHORTWAVE IMPACTS THE
AREA. UNCERTAINTY WITH THE MODELS INCREASES SUNDAY NIGHT AND FOR
THIS REASON HAVE NOT INCREASED POPS AND KEPT AT LOWER CHANCE. THE
NAM WHICH HAS THE HIGHEST QPF/POPS SHOWS ISENTROPIC DOWNGLIDE. BY
MONDAY MORNING POPS WILL STEADILY DECREASE AS SUBSIDENCE MOVES INTO
THE ENTIRE FA BY AFTERNOON. LOW POPS WILL BE RESTRICTED TO THE
SOUTHWEST FA FOR THE MORNING AND AFTERNOON PERIOD WITH NIL POPS
ELSEWHERE.
MIN TEMPERATURES WILL COOL ABOUT 5 DEGREES BY SUNDAY NIGHT WITH
READINGS FROM 60 TO 65. MAX TEMPERATURES WILL COOL FROM THE UPPER
70S WEST TO THE UPPER 80S EAST ON SUNDAY TO 75 TO 85 MONDAY.
