11 AM. UPDATED ZFP AND HWO ACCORDINGLY. NO OTHER CHANGES WE MADE.

.PREV DISCUSSION... /ISSUED 430 AM MDT WED MAR 28 2007/
SHORT TERM...THROUGH THURSDAY NIGHT...VERY ACTIVE PERIOD IN STORE
WITH A FICKLE UPPER LOW PLAYING HAVOC WITH THE MODELS AND THIS
FORECAST. BROAD CIRCULATION EVIDENT ON IR IMAGERY THIS HOUR WITH
SUBTLE RETROGRESSION NOTED. THE RIDGE OVER THE CENTRAL CONUS IS
SEVERELY INHIBITING EASTWARD PROGRESSION RIGHT NOW...AND EACH MODEL
HAS A DISTINCT SCENARIO FOR ITS MEANDERING. THE UKMET/CANADIAN
TANDEM HAS BEEN THE MOST RELIABLE WITH THIS SYSTEM TO DATE...SO
WILL AGAIN TAKE HPC ADVICE OF FOLLOWING IT. ONE OF MANY CONCERNS
FOR TODAY WILL BE THE WIND POTENTIAL IN THE PANHANDLE. GUIDANCE
PACKAGES ALL INDICATE ADVISORY CRITERIA THIS AFTERNOON FROM A
CLIMATOLOGICALLY RARE DIRECTION FOR HIGH WINDS...BUT GIVEN
PERSISTENCE AND STRENGTH OF THE LOW...HAVE DECIDED TO HOIST AN
ADVY. ANOTHER CONSEQUENCE OF THIS STRONG UPSLOPE WIND HAS BEEN
OFF AND ON FOG IN THE THE CHEYENNE AREA AND WESTWARD THROUGH THE
SOUTHERN LARAMIE RANGE. THE STRATUS IS INTERSECTING THE GROUND
INTERMITTENTLY...SO DECIDED TO GO WITH ANOTHER DENSE FOG ADVY MUCH
LIKE 24 HOURS AGO.
MOVING ON...HARD TO PIN DOWN POP REGIME RIGHT NOW...WITH WAVE
AFTER WAVE OF PRECIP UPSTREAM...AND DIFFERING TIMINGS OF UPPER
ENHANCEMENT FEATURES AMONG AVAILABLE MODELS...AND
UNFORTUNATELY...THE AFOREMENTIONED RELIABLE MODELS HAVE THE LEAST
RESOLUTION. REGARDLESS...HAVE BROADBRUSHED HIGH POPS ACROSS MOST
OF THE CWA THROUGH THE ENTIRE SHORT TERM. THE FOCUS WILL BE THE
NORTHERN HALF WHERE UPSLOPE WILL BE MAXIMIZED. THINK CHEYENNE
ITSELF WILL HAVE THE LEAST PRECIP. HAVE UPGRADED THE WINTER
HIGHLIGHT TO A WARNING PER COLLABORATION WITH NEIGHBORS AND HPC.
THIS COULD BE A LONG LIVED EVENT WITH ONE TO TWO FEET IN THE
MOUNTAINS. THE SNOW LEVEL WILL FALL FROM 9000 FEET THROUGHOUT THE
DAY AS THE PACIFIC FRONT SWEEPS THROUGH THE REGION. SFC ANALYSIS
SUGGESTS THE COLD FRONT IS ON TRACK FOR A NAM VERIFICATION...SO
EXPECTING FROPA THROUGH THE CWA BY 00Z. THIS LEAVES A FEW HOURS OF
PRE FRONTAL MOISTURE FEED INTO A VERY SHEARED ENVIRONMENT IN THE
PANHANDLE. HAVE INCLUDED SCT TSMS WITH POSSIBLE SEVERE AFTER NOON.
LONG TERM...FRI THRU TUE...AREA IS STILL UNDER THE INFLUENCE OF THE
LINGERING UPPER LOW FRI INTO FRI NIGHT WITH SOME SNOW SHWRS MAINLY
IN THE MTNS. MAINLY DRY AND WARMER SAT INTO SUN AS W FLOW BREAKS
THRU ACROSS THE REGION. MODELS NOT TOO SURE ABOUT STRENGTH/TIMING
OF AN UPPER TROF WHICH WILL MOVE THRU SOMETIME MON OR TUE...00Z
ECMWF IS DEEPER WITH TROF. WILL HOLD OFF ON ANY PCPN FOR NOW GIVEN
UNCERTAINTY.
AVIATION...THE UPPER LOW SPINNING TO THE WEST WILL CREATE
INTERMITTENT IFR AND OCCASIONALLY LIFR THROUGH TOMORROW.
