AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
225 PM MDT TUE MAR 29 2011

.SHORT TERM...TONIGHT THROUGH THURSDAY...
THE HEIGHTS ALOFT SLOWLY RISE OVER THE REGION THROUGH THURSDAY.
STRONG NORTHWEST WIND FLOW ALOFT WILL RESULT OVER THE CWA WEDNESDAY
THROUGH THURSDAY.  THE MAIN WEATHER CONCERN WILL BE THE POTENTIAL
FOR STRONG WINDS OVER PARTS OF THE CWA WEDNESDAY AFTERNOON AND
THURSDAY.  THE 300 MB CURRENTLY OVER THE PACIFIC NORTHWEST WILL
SHIFT EAST THROUGH THURSDAY.  FOR WEDNESDAY MORNING...THE CWA WILL
BE ON THE ANTICYCLONIC SIDE OF THE 130 KNOT JET AT 300 MB.  THE
300 MB JET WILL THEN CONTINUE EAST WITH THE CWA ON THE ANTICYCLONIC
SIDE OF THE FEATURE WEDNESDAY NIGHT AND THURSDAY.  THE 700 MB
WINDS FROM THE MODELS ARE EXPECTED TO BE FROM 45 TO 55 KNOTS OVER
THE WYOMING PART OF THE CWA DURING THAT TIME...WITH 35 TO 50 KNOTS
OVER THE PANHANDLE.  THE LOW LEVEL HEIGHT DIFFERENCE ACROSS THE
CWA INCREASES AS WELL WEDNESDAY WITH THE KCAG TO KCPR SEGMENT
BECOMING FAVORABLE FOR HIGH WINDS WEDNESDAY AFTERNOON AND INTO
THURSDAY MORNING.  WILL GO AHEAD AND ISSUE A HIGH WIND WATCH FOR
18Z WEDNESDAY TO 15Z THURSDAY FOR SOME AREAS ALONG AND WEST OF THE
LARAMIE RANGE.  ADVISORY WIND SPEEDS ARE LIKELY THURSDAY OVER THE
PANHANDLE.

AS HEIGHTS ALOFT AND 700 MB TEMPERATURES SLOWLY INCREASE BY THURSDAY
THE SURFACE TEMPERATURES WILL ALSO WARM.  READINGS WILL BE BACK TO
JUST ABOVE NORMAL IN MOST LOCATIONS WEDNESDAY NIGHT AND THURSDAY.
THE OTHER WEATHER CONCERN FOR THIS PART OF THE FORECAST WILL BE THE
COVERAGE OF SHOWERS OVER THE CWA AND SNOW AMOUNTS FOR THE MOUNTAINS.
THE CURRENT SURFACE BOUNDRY OVER EASTERN WYOMING WILL REMAIN OVER
THAT VICINITY THROUGH WEDNESDAY AND WILL THEN MOVE SLOWLY EAST.
MODELS MOVE A SURFACE COLD FRONT ACROSS MUCH OF THE CWA WEDNESDAY
NIGHT AND THURSDAY MORNING.  MODELS DEVELOP QPF OVER THE CWA
WEDNESDAY THROUGH THURSDAY...WITH THE GFS MORE WIDESPREAD IN THEIR
DEPICTION.  THE QPF SEEMS TO BE PRODUCED BY THE PROXIMITY OF THE
JET...AT LEAST ON WEDNESDAY...AND MID LEVEL CONVERGENCE AND SURFACE
FORCING WEDNESDAY NIGHT AND THRUSDAY MORNING.  THE PRECIPITATION
WILL BE WIDESPREAD OVER THE MOUNTAINS...WITH SEVERAL INCHES OF SNOW
EACH 12 HOUR PERIOD STARTING LATE TONIGHT OR WEDNESDAY MORNING.
OTHERWISE...A SCATTERED INSTANEOUS COVERAGE OF SHOWERS WILL AFFECT
THE CWA WEDNESDAY THROUGH THURSDAY MORNING...ESPECIALLY OVER THE
NORTHEAST THIRD.  PRECIPITATION TYPE WILL BE MAINLY IN THE FORM
OF RAIN EAST OF THE LARAMIE RANGE AND SNOW WEST OF THE LARAMIE
RANGE.

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY....
CONFIDENCE HIGH IN NAM...GFS AND ECMWF MODEL SOLUTIONS DUE TO MODEL
SIMILAR SYNOPTIC PATTERNS. 500 MB PATTERN SIMILAR ON FRIDAY WITH
NAM...GFS AND ECMWF SHOWING BRISK NORTHWEST FLOW ALOFT ACROSS
WYOMING AND NEBRASKA. ON SATURDAY...12Z ECMWF AND GFS BACK FLOW
ALOFT ACROSS WYOMING TO WEST AND SOUTHWEST AHEAD OF NEXT SHORTWAVE
TROUGH. ON SUNDAY...HIGH AMPLITUDE POSITIVE TILT SHORTWAVE DEVELOPS
OVER MONTANA...WYOMING AND IDAHO. 29/12Z GFS AND ECMWF MOVE THIS
TROUGH TO THE NORTHERN MISSISSIPPI VALLEY ON MONDAY WITH NORTHWEST
FLOW ALOFT ACROSS WYOMING. ON TUESDAY...12Z ECMWF AND GFS SIMILAR
IN SHOWING STRONG ZONAL FLOW ALOFT ACROSS WYOMING.

THURSDAY NIGHT...WINDY WITH DEEP UNIDIRECTIONAL NORTHWEST WINDS AND
STRONG GRADIENTS AND ISOTACHS FROM THE SURFACE THROUGH 700 MB.

FRIDAY...SIGNIFICANT WARMING TREND AS FLOW ALOFT BACKS WITH
RELATIVELY HIGH 500 MB HEIGHTS NEAR 5640 METERS AND 1000-500 MB
THICKNESSES NEAR 5610 METERS. SLIGHT CHANCE OF PRECIPITATION ACROSS
OUR NORTHERN COUNTIES ALONG A FRONTAL BOUNDARY.

SATURDAY...QUITE MILD DAY FOR WARM WEATHER OUTDOOR ENTHUSIASTS AS
WINDS ALOFT BACK TO SOUTHWEST AND 1000-500 MB THICKNESSES NEAR 5670
METERS PRODUCING MAXIMUM TEMPERATURES 50S WEST AND 60S TO LOWER 70S
EAST DEPENDING ON THE OPACITY...THICKNESS...OF HIGH CLOUD COVER.

SUNDAY...STRONG COLD FRONT PROGGED TO SWEEP ACROSS OUR COUNTIES AS A
POTENT SHORTWAVE TROUGH MOVES ACROSS THE ROCKIES. FRONTAL TIMING
WILL BE CRUCIAL TO MAXIMUM TEMPERATURE FORECAST. IMPOSSIBLE TO TIME
COLD FRONT ACCURATELY FIVE DAYS OUT...THUS WILL BLEND MAXIMUM
TEMPERATURES WITH OUR NEIGHBORING OFFICES IN DENVER/BOULDER...GRAND
JUNCTION...RIVERTON...RAPID CITY AND NORTH PLATTE. GFS LIKELY
OVERDONE ON CLOUDS AND QPF...AS IS ITS TENDENCY IN THE LONG RANGE...
THOUGH WILL HAVE AT LEAST 30 TO 70 PERCENT PROBABILITY OF
PRECIPITATION...POPS...OVER OUR COUNTIES WITH LIFT FROM PASSING
SHORTWAVE TROUGH AND ADEQUATE LOW AND MID LEVEL MOISTURE.

MONDAY...PRECIPITATION DECREASES IN COVERAGE FROM NORTH TO SOUTH AS
THE SHORTWAVE TROUGH MOVES SOUTHEAST OF OUR COUNTIES. HIGH
TEMPERATURES IN THE 30S AND 40S WITH 5430 METER 1000-500 MB
THICKNESSES.

TUESDAY...WARMING TREND ON TAP AS FLOW ALOFT BECOMES WESTERLY AND
1000-500 MB THICKNESSES NEAR 5620 METERS...PRODUCING MAXIMUM
TEMPERATURES IN THE 40S AND 50S.

&&

.AVIATION...00Z TAFS. VFR...EXCEPT LOCALIZED MVFR ACROSS CARBON
COUNTY THROUGH 06Z. ACROSS CARBON COUNTY...WEST TO SOUTHWEST WINDS
INCREASING SIGNIFICANTLY AFTER 07Z PRODUCING MOUNTAIN WAVE
TURBULENCE AND LEE EDDY EFFECTS.

&&

.FIRE WEATHER...
STRONG WEST TO NORTHWEST SURFACE WINDS WILL AFFECT MUCH OF THE CWA
WEDNESDAY THROUGH THURSDAY.  TEMPERATURES WILL SLOWLY WARM OVER
THE REGION...WITH WELL ABOVE NORMAL TEMPERATURES EXPECTED FRIDAY
AND SATURDAY.  SURFACE WINDS WILL BE LIGHTER DURING THOSE DAYS.
MOUNTAIN SNOW AND SOME RAIN OR SNOW SHOWERS OVER THE LOWER
ELEVATIONS CAN BE EXPECTED WEDNESDAY AND THURSDAY AND THEN DRY
WEATHER FOR FRIDAY AND SATURDAY.  MINIMUM RELATIVE HUMIDITY
VALUES WILL BE BETWEEN 25 AND 40 PERCENT OVER THE LOWER ELEVATIONS
WEDNESDAY AND THURSDAY AND 15 TO 25 PERCENT FRIDAY AND SATURDAY.
THE NEXT STORM SYSTEM WILL BRING COOLER TEMPERATURES AND A GOOD
CHANCE OF SHOWERS TO THE CWA BY SUNDAY NIGHT AND CONTINUING
THROUGH EARLY NEXT WEEK.

&&

.HYDROLOGY...
RELEASES FROM UPSTREAM RESERVOIRS IN SOUTHEAST WYOMING WILL
CONTINUE TO PRODUCE HIGH WATER LEVELS ON THE NORTH PLATTE RIVER
BELOW GUERNSEY RESERVOIR. AT THIS TIME...THE WATER LEVELS ARE
FORECAST TO REMAIN NEARLY SIMILAR FOR THE REST OF THE WEEK IN THE
WESTERN NEBRASKA PANHANDLE AND JUST BELOW FLOOD STAGE. ADDITIONAL
RAIN AND SNOW OVER THE AREA THROUGH MID WEEK MAY PRODUCE A SMALL
INCREASE IN THE WATER LEVELS ON THE NORTH PLATTE RIVER DOWNSTREAM
OF GUERNSEY RESERVOIR.

.CYS WATCHES/WARNINGS/ADVISORIES...
