224 PM MDT SUN JUL 8 2007

.SHORT TERM...TONIGHT THROUGH TUESDAY.

TONIGHT...PASSAGE OF SHORTWAVE TROUGH AT PEAK HEATING ALONG WITH
UPSLOPE FLOW REGIME EAST OF THE LARAMIE RANGE WILL PROVIDE LIFT
NEEDED FOR SCATTERED TO NUMEROUS THUNDERSTORMS ALONG/EAST OF THE
LARAMIE RANGE...ESPECIALLY WITH DECENT LOW/MID LEVEL MOISTURE IN PLACE.
CONVECTIVE PARAMETERS SUCH AS LOW/MID LEVEL THETA-E
AXII...BUOYANCY...DIRECTIONAL/SPEED SHEAR...STEEP LAPSE RATES
POINT TO SOME OF THE STORMS BECOMING SEVERE THROUGH THIS EVENING
ACROSS THE SPC DAY ONE SLIGHT RISK AREA...WHICH IS WELL PLACED.
STEERING FLOW ALOFT WEAK...THUS SOME HEAVY RAINERS LOOK LIKELY.
EXPECTING CONVECTIVE CLUSTERS SUCH AS MULTICELL CLUSTERS
TO DEVELOP THROUGH THIS EVENING WHICH BOTH NAM/GFS SUGGEST.
BOUNDARY LAYER PROGS SUGGEST AREAS OF LOW CLOUDS LATE TONIGHT
ACROSS OUR SOUTHEAST ZONES.

MONDAY...MORE PRONOUNCED NORTH TO SOUTH ORIENTED LOW/MID LEVEL
THETA-E AXII DEVELOP ALONG THE LARAMIE RANGE. HOWEVER...WARM MID
LEVEL TEMPERATURES ACTING AS A CAPPING INVERSION WILL LIMIT AREAL
THUNDERSTORM COVERAGE IN THE AFTENROON AND EVENING AS IT WILL BE
MORE DIFFICULT TO OVERCOME THE CONVECTIVE INHIBITION...ALSO KNOWN
AS CIN.

MONDAY NIGHT...COLD FRONTAL PASSAGE WILL INTRODUCE A DRIER AIRMASS
INTO OUR NECK OF THE WOODS...FLUSHING OUT MUCH OF THE LOW LEVEL
MOISTURE.

TUESDAY...DRIER AND MORE STABLE AFTERNOON/EVENING IN THE WAKE OF
THE SIGNIFICANT COLD FRONT. LOW/MID LEVEL THETA-E RIDGE AXII WILL
BE SUPPRESSED TO CARBON COUNTY WITH NEGATIVE THETA-E ADVECTION
PROVIDING A DAMPER AND INHIBITING THUNDERSTORMS. PLEASANT AFTERNOON
FOR OUTDOOR WEATHER ENTHUSIASTS WANTING TO ENJOY A BRIEF RESPITE
FROM THE EARLY JULY HEAT.   RUBIN

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...
MAIN CHANGE TO THE LONG TERM FORECAST THIS MORNING WAS A WELL
COORDINATED DROP IN HIGH TEMPERATURES...ESPECIALLY FOR THE MIDDLE
OF NEXT WEEK. THIS IS THE PERIOD WHEN MID-LEVEL TEMPERATURES ARE
FORECAST BY THE MEDIUM RANGE MODELS TO SUPPORT SLIGHTLY BELOW NORMAL
TEMPERATURES.

OTHERWISE...THE INHERITED FORECAST CONTINUED TO LOOK REASONABLE
WITH AFTERNOON AND EVENING THUNDERSTORMS POSSIBLE THROUGH THE
PERIOD AS WEAK DISTURBANCES MOVE OVER THE AREA IN NORTHWEST FLOW
ALOFT.

TEMPERATURES WILL GRADUALLY WARM TO NEAR NORMAL VALUES LATE IN THE
WEEK AND THROUGH NEXT WEEKEND AS THE UPPER LEVEL RIDGE SHIFTS EAST
OVER THE AREA AND A THERMAL RIDGE DEVELOPS BENEATH IT. CARPENTER
