238 AM MDT MON JUN 27 2011

.DISCUSSION...
237 AM MDT MON JUN 27 2011

EARLY MORNING WV IMAGERY AND H5 ANALYSIS SHOW WESTERLY FLOW ACROSS
HIGH PLAINS WITH SHORTWAVE TROUGH AXIS ACROSS NORTHERN PLAINS. PV
ANOMALY ON SOUTHERN EXTENT OF TROUGH OVER SOUTH DAKOTA DIGGING SOUTH
INTO NORTHERN NEBRASKA. THUNDERSTORMS HAVE DEVELOPED ACROSS NORTHERN
PARTS OF CWA AS COLD FRONT MOVED SOUTH OVER CWA. VERY MOIST/UNSTABLE
AIRMASS IN PLACE WILL SUPPORT FURTHER SHOWER/THUNDERSTORM
DEVELOPMENT GENERALLY NORTH OF INTERSTATE 70 AS SHORTWAVE ENERGY
PROGRESSES EASTWARD THROUGH 15Z. WILL NEED TO MONITOR
SATELLITE/RADAR TRENDS AND MAKE FURTHER ADJUSTMENTS TO FIRST 6HR
OF FORECAST AS NECESSARY.

LATEST GUIDANCE INDICATING 60KT H85 JET BUILDING OVER SE
CWA...COUPLED WITH 7MB PRESSURE RISES BEHIND THE FRONT. NOT SURE
THE STRONGEST WINDS WILL MIX TO THE SURFACE BUT THERE SHOULD BE A
PERIOD OF AT LEAST ADVISORY LEVEL WINDS EARLY THIS MORNING. WILL
BE ISSUING A WIND ADVISORY THROUGH 15Z OVER SE TIER OF COUNTIES.

COOLER AIRMASS SETTLING IN PLACE OVER CWA TODAY WITH H85 TEMPS
10-20C COLDER THAN 24HR PRIOR. I BUMPED TEMPS DOWN FOR THIS
AFTERNOON...HOWEVER WERE SOME 2M T GUIDANCE BE CORRECT I MAY STILL
BE 5-10F TOO WARM AT SOME LOCATIONS.

CENTRAL/HIGH PLAINS EXPECTED TO REMAIN ON NORTHERN EXTENT OF LARGE
SCALE RIDGE CENTERED OVER SOUTHERN CONUS THROUGH WED MORNING KEEPING
CWA IN WESTERLY FLOW...AND IN FAVORABLE LOCATION FOR SEVERAL
SHORTWAVES TO PASS WITHIN VICINITY OF AREA. COLD FRONT CURRENTLY
PASSING THROUGH CWA EXPECTED TO STALL SOUTH OF CWA AND WILL ACT AS
FOCUS FOR SHOWER/THUNDERSTORM REDEVELOPMENT SOUTH OF CWA THIS EVE
THROUGH TUE NIGHT. CURRENTLY STRONG CAP AND 100-700MB DRY LAYER
SHOULD INHIBIT CONVECTION OVER CWA DURING AFTERNOON PERIOD TODAY AND
DAYTIME PERIOD TUE...SO KEEPING POPS SILENT. BETTER CHANCES EXPECTED
DURING EVE/OVERNIGHT PERIODS TODAY AND TUE AS CAP WEAKENS AND
SHORTWAVE ENERGY COUPLED WITH H85 JET/THETA-E SUPPORT THUNDERSTORM
DEVELOPMENT.

SOUTHERN CONUS RIDGE EXPECTED TO BUILD NORTH OVER CWA WED...PUSHING
STORM TRACK NORTHWARD. TRI-STATE AREA LOOKS TO BE IN LINE FOR
SEVERAL VERY HOT/DRY DAYS WED/THU...WITH 100 DEGREES COMMON ACROSS
THE AREA. WILL NEED TO MONITOR BOTH DAYS FOR POTENTIAL FIRE WX
CONCERNS WITH WINDS/RH BOTH CURRENTLY FORECAST TO BE WITHIN RED FLAG
CRITERIA.

DAYS 4-7...NO CHANGES MADE.

.AVIATION...
1100 PM MDT SUN JUN 26 2011

FOR THE 06Z TAFS...THUNDERSTORMS ARE POSSIBLE TONIGHT...WITH BETTER
CHANCES AT KMCK THAN KGLD THROUGH 09Z OR SO. HAVE INCLUDED CB AT
KMCK...AS CAP HAS BEEN DECREASING NEAR THE TERMINAL BUT IS STILL
PRESENT. A FRONT WILL PASS THROUGH THE TERMINALS AFTER 06Z
TONIGHT...CAUSING WINDS TO SHIFT TO NORTHERLY AND BECOME GUSTY. IFR
CEILINGS ARE ALSO EXPECTED BEHIND THE FRONT. MODELS SUGGEST THAT
VISIBILITIES WILL DECREASE AS CEILINGS LOWER...BUT ANY FOG WOULD
NEED TO BE ADVECTION FOG DUE TO THE GUSTY WINDS. DEW POINTS SHOULD
BE DECREASING AS AIR MOVES IN FROM THE NORTH...THOUGH THERE MAY BE A
BRIEF PERIOD FOR REDUCED VIS BEFORE DEW POINTS BEGIN DECREASING. IFR
CEILINGS WILL SCATTER AS THE FRONT MOVES FURTHER AWAY AND MIXING
INCREASES DURING THE DAYTIME. WINDS WILL ALSO DECREASE AS THE FRONT
MOVES AWAY.
