AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
300 AM MDT WED APR 9 2008

.SHORT TERM...TODAY THROUGH THURSDAY.

TODAY...TWO MAIN AREAS OF PRECIPITATION WILL DEVELOP THIS MORNING...ONE IN
CARBON AND ALBANY COUNTIES IN DYNAMICAL LIFT AHEAD OF APPROACHING
SHORTWAVE TROUGH AND THE OTHER FROM DOUGLAS TO CHADRON TO
SCOTTSBLUFF IN WARM AIR ADVECTION LIFT. FAR SOUTHEAST WYOMING WILL
BE DRYSLOTTED THIS MORNING...THUS LESS PRECIPITATION COVERAGE. FOR THIS
AFTERNOON...HIGHEST SNOW COVERAGE WILL BE WEST OF THE LARAMIE RANGE
ALONG THE INVERTED SURFACE TROUGH ACTING AS A LOW LEVEL CONVERGENCE
AXIS. EXCELLENT AND PROACTIVE CALL ON THE WIND ADVISORY FOR THE
NEBRASKA PANHANDLE BY THE TUESDAY DAY SHIFT SHORT TERM
METEOROLOGIST...AS THE GRADIENT SUPPORTS AT LEAST 25-35 MPH WINDS
THERE. ONLY SNOWFALL ACCUMULATIONS THROUGH LATE AFTERNOON WILL BE
1-3 INCHES ACROSS THE SNOWY RANGE.

TONIGHT...TRACK OF SHORTWAVE TROUGH CRITICAL. NAM FURTHER SOUTH
TAKING THE 500/700 MB LOWS ACROSS THE OKLAHOMA PANHANDLE WHILE GFS
TRACKS THE SAME LOWS ACROSS SOUTHEAST COLORADO. GENERAL CONSENSUS IS
TO FAVOR FURTHER NORTH GFS DEPICTION. WITH ATMOSPHERIC COLUMN
SATURATED...DYNAMICAL LIFT...UPSLOPE LIFT...WIDESPREAD SNOW EXPECTED
EAST OF THE LARAMIE RANGE. EVENING TEMPERATURES RELATIVELY MILD AND
WILL NOT SUPPORT MUCH ACCUMULATING SNOW EAST OF THE LARAMIE RANGE.
EXPECT SNOWFALL ACCUMULATIONS OF 1-4 INCHES AFTER MIDNIGHT SOUTHEAST
OF A RAWLINS TO LUSK LINE. IN COORDINATION WITH OUR NEIGHBORING
OFFICES...WILL CONTINUE THE INHERITED WINTER STORM WATCH AREA AND
TIMES AND LET THE DAY SHIFT MAKE FINAL DETERMINATION OF SNOW
ADVISORY ISSUANCE. HAVE DECREASED SNOWFALL AMOUNTS MORE IN LINE WITH
GFS TRENDS AND ESPECIALLY HPC QPF GUIDANCE. GUIDANCE POPS TOO LOW IN
MOST PLACES AND HAVE BOOSTED ACCORDINGLY. BEST GUESS WOULD BE LOW
END SNOW ADVISORY CRITERIA...IF THAT...ACROSS FAR SOUTHEAST WYOMING
AND WESTERN NEBRASKA COUNTIES...AS WELL AS THE LARAMIE
VALLEY...SNOWY RANGE AND SOUTHERN LARAMIE RANGE.

THURSDAY...CLOSED UPPER LOW HANDLED SIMILARLY BY NAM/GFS...IN
TRACKING THE UPPER TROUGH TO SOUTHEAST NEBRASKA BY 00Z/FRIDAY. THE
HEAVIER QPF TRACK AND SNOWFALL WILL REMAIN EAST AND SOUTHEAST OF OUR
COUNTIES. DECENT SNOW CHANCES CONTINUE WITH WRAPAROUND AND UPSLOPE
NORTH OF THE CHEYENNE RIDGE WITH LITTLE ADDITIONAL ACCUMULATIONS IN
THE AFTERNOON DUE TO DECREASE IN QPF. RAW BLUSTERY DAY WITH PROGGED
GRADIENTS AND COLD AIR ADVECTION. COLDER GFS MOS HIGHS BETTER THAN
WARMER NAM HIGHS. TOTAL STORM SNOWFALL AMOUNTS OF 3-6 INCHES
EXPECTED AT CHEYENNE...LARAMIE...SCOTTSBLUFF...CHADRON...SIDNEY AND
KIMBALL WITH 2 INCHES OR LESS AT OTHER LOWER ELEVATION LOCALES.
RUBIN

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY...
THE CWA WILL STILL BE INFLUENCED THROUGH SATURDAY BY THE STORM
SYSTEM DISCUSSED IN THE SHORT TERM. MODELS MOVE THE UPPER LOW FROM
THE CENTRAL KANSAS AREA AT 00Z FRIDAY TO THE GREAT LAKES AT 00Z
SUNDAY.  MODELS DIFFER SOME ON THE MOVEMENT OF THE FEATURE WITH
THE ECMWF AND CANADIAN MODELS FURTHER WEST...OVER WESTERN IOWA BY
00Z SATURDAY...THAN THE GFS...NAM...NOGAPS AND SREF.  FOR NOW WILL
LEAN TOWARD THE HPC FAVORED ECMWF AND CANADIAN DEPICTION AND SO
WILL BUMP UP POPS AND WINDS THROUGH EARLY FRIDAY NIGHT OVER MAINLY
THE EAST PART OF THE CWA.  THE BULK OF THE LINGERING STRATIFORM SNOW
WILL LINGER THROUGH THURSDAY NIGHT AS THE BOUNDARY LAYER UPSLOPE
WIND FLOW GRADUALLY WEAKENS.  THEN THE CYCLONIC FLOW ALOFT WILL
PERSIST OVER THE CWA THROUGH FRIDAY EVENING PRODUCING MORE
CONVECTIVE SNOW SHOWERS.  HEIGHTS ALOFT DO SLOWLY RISE OVER THE
REGION FRIDAY THROUGH SATURDAY WITH THE 300 MB JET AXIS MOVING ONTO
THE PLAINS THROUGH THAT TIME.  THE STRONG WINDS ALOFT FRIDAY AND
SATURDAY WILL MAKE FOR A COUPLE OF WINDY DAYS AND AT LEAST A WIND
ADVISORY MAY BE NEEDED FOR THE PANHANDLE ON THOSE DAYS.  THE HIGH
TEMPERATURES REMAIN BELOW NORMAL FOR FRIDAY AND THEN MODERATE ON
SATURDAY.  SUNDAY AND MONDAY ON ALL MEDIUM RANGE MODELS WILL BE MILD
AND DRY OVER THE CWA AS THE RIDGE ALOFT WILL BE OVER THE ROCKIES.
AT THIS TIME...MONDAY APPEARS TO BE THE WARMEST DAY WITH READINGS
WELL ABOVE NORMAL VALUES.  MODELS THEN DIFFER AGAIN TOWARDS THE MID
PART OF NEXT WEEK WITH THE GFS AND DGEX SLOWLY MOVING THE UPPER
LEVEL RIDGE AXIS EAST AND OVER THE PLAINS.  THAT WOULD KEEP THE CWA
MILD AND DRY THROUGH NEXT WEDNESDAY.  MEANWHILE THE ECMWF...CANADIAN
AND NOGAPS MOVE A SHORTWAVE TROUGH SLOWLY SOUTH FROM CANADA YIELDING
COOLER TEMPERATURES BUT STILL DRY.  GOING FORECAST IS FOR MILD AND
DRY AND WILL KEEP IT SO UNTIL BETTER MODEL CONSENSUS IS REACHED.
