AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
640 AM MDT THU APR 21 2011

.UPDATE...SOUTH WINDS INCREASED THIS MORNING IN THE CHADRON
AREA...SO MUCH SO THAT GUSTS UP TO 60 MPH WERE REPORTED IN TOWN
AND AT THE ASOS. WENT AHEAD AND HOISTED A HIGH WIND WARNING FOR
DAWES COUNTY THIS MORNING...WITH A EMPHASIS ON THE NORTHERN HALF
OF THE COUNTY AS THE GRADIENT WIND WAS LIKELY ENHANCE BY
DOWNSLOPING OFF THE PINE RIDGE. THE TIGHT GRADIENT IS EXPECTED TO
SHIFT EAST THROUGH THE MORNING SO THE WINDS WILL SLACKEN BY NOON.

&&

.PREV DISCUSSION... /ISSUED 444 AM MDT THU APR 21 2011/

SHORT TERM...TODAY THROUGH FRIDAY NIGHT...SNOW LEVELS SLOWLY
TO DROPPING AS ONLY THE PAST HOUR ARE WE BEGINNING TO SEE SNOW AT
CYS...WITH LAR A MIX AS WELL...AND HIGHER ELEVATIONS OF THE
SOUTHERN LARAMIE RANGE ALL SNOW ACCORDING TO THE WEBCAMS. MODERATE
SNOW SHOWERS MOVED UP FROM NW COLORADO AND ACROSS THE SOUTHERN
LARAMIE RANGE SINCE MIDNIGHT...WITH SOME ACCUMULATION EVIDENT ON
WEBCAMS IN THE GRASSY AREAS AND ON ROADWAYS. STRONG ISENTROPIC
LIFT IS EXPECTED TO DIMINISH THROUGH THE MORNING AND COMBINED WITH
WARMING AND ENTRAINMENT OF DRIER AIR IN THE MIDLEVELS...WHICH IS
BEGINNING TO SHOW OUT WEST WITH THE GRADUAL CLEARING OF ECHOES ON
RADAR...EXPECT THE TRANSITION TO LIGHT SNOW OR FLURRIES THROUGH
THE MORNING OVER THE AREA. MAYBE AN ADDITIONAL INCH OR TWO OVER
THIS AREA BY SUNRISE. FORECAST SOUNDINGS FROM NAM BUFR SHOW
WARMING OF THE LOW LEVELS AT KCYS SO COULD TRANSITION BACK TO A
COLD RAIN AROUND SUNRISE IF ANY SHOWERS REMAIN. OVER THE NEBRASKA
PANHANDLE...BREEZY SOUTHERLY WINDS HAVE BEEN PERSISTENT THROUGH
THE NIGHT AS THE SFC LOW OVER OVER NORTHCENTRAL WYOMING DEEPENS.
WILL CONTINUE TO BE BREEZY WITH WIDESPREAD GUSTS OF 30 TO 40 MPH
AND A FEW LOCAL SPOTS GUSTING AS HIGH AS 50 MPH AS THE LOW SLOWLY
SHIFTS SOUTHEAST THROUGH THE MORNING. THESE WINDS WILL THEN SLACKEN
SOMEWHAT THROUGH THE DAY.

A MORE ENERGETIC SHORTWAVE WILL APPROACH THE CWA FROM THE SOUTHWEST
THIS AFTERNOON. MODELS ARE CONTINUING TO RESOLVE MODEST CAPE
VALUES OF 500 TO 1000 J/KG THIS AFTERNOON...AND IF ENOUGH
CLEARING IN THE CLOUDS CAN OCCUR ONCE THE WAVE CURRENTLY OVERHEAD
PUSHES EAST...FEEL THESE VALUES CAN BE REALIZED. THUS CONTINUED
THE MENTION OF THUNDER FOR THIS AFTERNOON...BEGINNING IN THE WEST
AROUND NOON AND THEN GRADUALLY SHIFTING CHANCES EAST THROUGH THE
AFTERNOON AS THE MAIN AREA OF CONVERGENCE SHIFTS EAST. FAIRLY
MOIST PROFILE WITH PWATS APPROACHING HALF INCH ACROSS MUCH OF THE
AREA WOULD SUGGEST A THREAT FOR SMALL HAIL WITH SOME OF THE STORMS
AND GUSTY WINDS.

A STRONGER PACIFIC COLD FRONT WILL MOVE FROM WEST TO EAST EARLY
FRIDAY MORNING AND THE SFC LOW WILL SHIFT EAST OUT INTO THE PLAINS.
IN THE WAKE OF THE FRONT AND SFC LOW...WEST TO NORTHWEST WINDS WILL
INCREASE AND BECOME STRONG DUE TO THE STRENGTHENING PRESSURE
GRADIENT. MAINTAINED THE HIGH WIND WATCH ACROSS THE AREA AS GUIDANCE
STILL HINTS AT THESE STRONGER WINDS. OROGRAPHIC RAIN/SNOW SHOWERS
ARE ALSO A POSSIBILITY OFF THE NORTHERN LARAMIE RANGE AND
BIGHORN MOUNTAINS IN THE AFTERNOON. HIGH PRESSURE WILL BUILD IN
QUICK OVERNIGHT...WHICH WILL RELAX THE WINDS AND FILTER IN CHILLY
TEMPERATURES BY SATURDAY MORNING.

LONG TERM...SATURDAY THROUGH WEDNESDAY...
A COOLER THAN NORMAL PATTERN WILL BE IN PLACE THROUGH THE EXTENDED
FORECAST PERIODS...WITH A PROGRESSIVE SERIES OF SHORT-WAVE
DISTURBANCES MOVING ACROSS THE SOUTHEAST WYOMING AND WESTERN
NEBRASKA PANHANDLE AREAS. A SPLIT FLOW ALOFT WILL BE PRESENT MOVING
ONTO THE PACIFIC COAST NEAR THE STATE LINE BETWEEN OREGON AND
CALIFORNIA AND THEN SPLITTING ACROSS THE ROCKIES. THE FORECAST AREA
WILL BE UNDER THE INFLUENCE OF THE SOUTHERN STREAM OF THE SPLIT WITH
SOUTHWEST FLOW AHEAD OF A SHORT-WAVE DISTURBANCE SATURDAY INTO EARLY
SUNDAY. THEN THE MAIN TROUGH WILL BECOME NEGATIVELY TILTED AND MOVE
INTO THE AREA SUNDAY NIGHT AND INTO MONDAY...AND THIS WILL OCCUR
OVER THE TOP OF UPSLOPE LOW LEVEL WINDS ALONG THE LARAMIE RANGE. THE
RESULT WILL BE THE POTENTIAL FOR WIDESPREAD PRECIPITATION. BY MONDAY
NIGHT THE FAIRLY WELL STACKED LOW...MID AND UPPER LEVEL LOWS EAST OF
THE AREA WILL CONTINUE TO MOVE NORTHEAST. WRAP AROUND PRECIPITATION
WILL LINGER ACROSS THE EAST MONDAY NIGHT ALONG WITH CONTINUING
MOUNTAIN SNOW SHOWERS DUE TO UPPER LEVEL ENERGY DIGGING TO THE SOUTH
AND WEST OF THE AREA. TUESDAY WILL HAVE SHOWERY WEATHER ACROSS THE
AREA AS THE UPPER TROUGH MOVES OVERHEAD...AND TUESDAY NIGHT AND
WEDNESDAY WILL HAVE DECREASING PRECIPITATION CHANCES AS THE NEXT
UPPER LEVEL RIDGE DEVELOPS.

AVIATION...PRECIPITATION OVERRUNNING THE SURFACE BOUNDARY
CURRENTLY ALIGNED ROUGHLY ALONG THE LARAMIE RANGE WILL CONTINUE
THIS MORNING ALONG AND SOUTH OF A LINE FROM NEAR KRWL TO KAIA.
AFTER A BRIEF BREAK MIDDAY...THE NEXT BATCH OF ENERGY ALOFT WILL
CREATE INCREASING CHANCES FOR SHOWERS AND THUNDERSTORMS FROM WEST
TO EAST AS THE SURFACE BOUNDARY IS EJECTED ONTO THE HIGH PLAINS.
WINDS WILL STRENGTHEN FOLLOWING THE SURFACE BOUNDARY PASSAGE LATE
THURSDAY NIGHT AND INTO FRIDAY...AND WILL GENERALLY BE FROM THE
WEST.

FIRE WEATHER...A STORM SYSTEM WILL BRING A GOOD CHANCE FOR RAIN
AND HIGH ELEVATION SNOW TO THE REGION TODAY. ISOLATED
THUNDERSTORMS ARE ALSO POSSIBLE THIS AFTERNOON...WITH GUSTY WINDS
AND MODERATE RAINFALL POSSIBLE AT TIMES. A PACIFIC COLD FRONTAL
PASSAGE EARLY FRIDAY MORNING WILL BRING STRONG WEST WINDS TO THE
REGION ON FRIDAY ALONG WITH LOWER AFTERNOON MINIMUM RELATIVE
HUMIDITIES DOWN TO AROUND 30 PERCENT.

HYDROLOGY...THE GAGE SITES AT BOTH HENRY AND MITCHELL ARE
EXPECTED TO REMAIN NEAR STEADY AND IN THE ACTION STAGE UNTIL
FURTHER NOTICE. ADDITIONAL RELEASES FROM GUERNSEY RESERVOIR WILL
CONTINUE...WITH MOST OF THE WATER DIVERTED TO IRRIGATION CANALS.
