AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
331 AM MDT SUN JUL 10 2011

.SHORT TERM...TODAY THROUGH MONDAY NIGHT...
EXPECT SIMILAR WEATHER TODAY AS YESTERDAY WITH WIDELY SCATTERED
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS THOUGH NOT A LARGE
COVERAGE.  INSTABILITIES AND SHEAR VALUES TO REMAIN RATHER LOW
ACROSS THE CWA TODAY SO STORMS SHOULD NOT BE TOO STRONG WITH JUST
GUSTY WINDS AND RAIN THE MAIN FEATURES WITH THEM.  SOME SUNSHINE
INTO EARLY THIS AFTERNOON WILL ALLOW TEMPERATURE TO BECOME QUITE
WARM ESPECUIALLY OVER THE PANHANDLE.  A FEW SHOWERS COULD CONTINUE
TONIGHT OVER MAINLY THE WESTERN AND NORTHERN PARTS OF THE CWA AS
MOISTURE CONTINUES TO ADVECT AROUND PERIPHERY OF UPPER HIGH OVER THE
SOUTHEASTERN PART OF THE COUNTRY.  MOISTURE AND INSTABILITY
INCREASES MONDAY ESPECIALLY EAST OF THE MTNS WHERE A WEAK BOUNDARY
SHOULD EXIST AS A MODEST LEE CYCLONE DEVELOPS OVER FAR EASTERN
COLORADO.  MORE WIDESPREAD SHOWERS AND STORMS EXPECTED EAST OF THE
MTNS MONDAY WHERE WEAK UPSLOPE FLOW WILL EXIST UNDER WESTERLY UPPER
FLOW.  A FEW STORMS COULD GET RATHER STRONG THOUGH SHEAR VALUES
STILL NOT TOO HIGH.  TEMPERATURES A LITTLE COOLER MONDAY WITH MORE
CLOUDINESS.

.LONG TERM...TUESDAY THROUGH SATURDAY...
THE SYNOPTIC PATTERN ALOFT FOR THIS PORTION OF THE FORECAST IS FOR
A RIDGE TO BUILD OVER THE PLAINS AND A TROUGH TO BE ALONG THE WEST
COAST.  SOUTHWEST WIND FLOW ALOFT AND INCREASINGLY WARM TEMPERATURES
IN THE MID LEVELS WILL RESULT OVER THE REGION.  A STATIONARY FRONT
WILL BE NEAR THE LARAMIE RANGE AT 12Z TUESDAY.  IT WILL MOVE EAST AS
A SURFACE TROUGH WEDNESDAY AND THURSDAY WITH THE FEATURE EAST OF THE
CWA BY 00Z FRIDAY.  A COLD FRONT WILL BE UPSTREAM OF THE CWA...BUT
MODELS KEEP THE FEATURE MAINLY NORTH AND WEST OF THE CWA THROUGH NEXT
SUNDAY AS IT PARALLELS THE SOUTHWEST FLOW ALOFT.

TUESDAY STILL LOOKS TO BE THE MOST ACTIVE DAY WITH ABUNDANT MOISTURE
OVER THE CWA.  IN ADDITION...MODELS DEPICT A FAIRLY SIGNIFICANT
SHORTWAVE TROUGH MOVING OVER THE REGION AND THE SURFACE BOUNDARY WILL
BE LOCATED NEAR THE LARAMIE RANGE.  BEST INSTABILITY WILL BE OVER AND
EAST OF THE LARAMIE RANGE IN SOUTHEAST WYOMING.  SURFACE TEMPERATURES
WILL BE COOLER BEHIND THE FRONT OVER THE PANHANDLE AND WILL KEEP THAT
PART OF THE CWA MORE STABLE.  PRECIPITABLE WATER VALUES WILL BE OVER
AN INCH OVER MUCH OF THE CWA ON TUESDAY.  THE RESULT SHOULD BE
THUNDERSTORMS OVER THE CWA TUESDAY AFTERNOON AND CONTINUING THROUGH
EARLY TUESDAY NIGHT.  THE MAIN CONCERN WILL BE THE POSSIBILITY OF
HEAVY RAINFALL FROM THE STORMS AND FLASH FLOODING.

THE MID AND UPPER LEVEL MOISTURE PLUME LOOKS TO BE SOUTH AND EAST OF
THE CWA LATER TUESDAY NIGHT AND CONTINUING THROUGH THURSDAY
MORNING.  THAT PERIOD SHOULD HAVE A MINIMUM OF LATE DAY STORMS.
MODELS BRING THE MID AND UPPER LEVEL MOISTURE PLUME BACK INTO THE
CWA THURSDAY AFTERNOON AND CONTINUING THROUGH NEXT SUNDAY.  THE
MODELS DIFFER ON ITS LOCATION...WITH THE GFS FURTHER EAST AND MAINLY
OVER THE SOUTHEAST HALF OF THE CWA.  MEANWHILE THE ECMWF IS FURTHER
WEST WITH THE MOISTURE PLUME AT THAT TIME.  FOR WEDNESDAY THROUGH
SATURDAY THE LOW LEVEL MOISTURE IS LOWER THAN IT HAS BEEN AND THEN
INCREASES NEXT SUNDAY.  SOME SHOWERS AND LATE DAY STORMS WILL FORM
UNDER THE MOISTURE PLUME...BUT SHOULD NOT BE AS WIDESPREAD OR
INTENSE AS THOSE OF TUESDAY DUE TO THE LOWER BOUNDARY LAYER KOISTURE
AVAILABLE.  WINDY CONDITIONS WILL BE PRESENT IN AREAS ALONG AND WEST
OF THE LARAMIE RANGE THURSDAY THROUGH SATURDAY.  THE COMBINATION OF
THE WINDS AND DRIER AIR NEAR THE SURFACE MAY INCREASE FIRE WEATHER
CONCERNS DURING THAT TIME.

&&

.AVIATION...12Z TAF ISSUANCE...
VFR CONDITIONS WILL CONTINUE OVER THE CWA THROUGH MONDAY.  SOME
THUNDERSTORMS CAN BE EXPECTED BETWEEN 20Z AND 01Z TODAY. SOUTHWEST
TO WEST SURFACE WINDS WILL GUST AS HIGH AS 30 KNOTS AFTER 16Z IN
AREAS ALONG AND WEST OF THE LARAMIE RANGE AND CONTINUE THROUGH 01Z.

&&

.FIRE WEATHER...
NO BIG CONCERNS ANTICIPATED INTO THE EARLY PART OF THE WEEK WITH
CHANCES FOR MAINLY AFTERNOON AND NIGHTTIME SHOWERS AND THUNDERSTORMS
AS MONSOONAL MOISTURE CONTINUES TO RIDE OVER THE REGION.  FUELS
REMAIN MOSTLY GREEN AND NON CRITICAL AND ADDITIONAL RAINS WILL KEEP
THEN THAT WAY FOR A WHILE.  A FEW LIGHTNING INDUCED FIRES POSSIBLE
BUT GROWTH POTENTIAL WILL BE LIMITED.

&&

.HYDROLOGY...
WATER LEVELS IN THE RIVERS AND STREAMS IN SOUTHEAST WYOMING HAVE
COME UP SOME ON FRIDAY AND SATURDAY AND WILL CONTINUE THROUGH
TODAY DUE TO RECENT HEAVY RAINFALL.  FLOOD WARNINGS EARLY THIS
MORNING ARE LIMITED TO THE UPPER NORTH PLATTE RIVER AT SARATOGA AND
SINCLAIR WITH THOSE SITES FALLING BELOW FLOOD STAGE LATE TONIGHT
THROUGH MONDAY EVENING.  WILL NEED TO CONSIDER A FLOOD WARNING FOR
THE LARAMIE RIVER AT LARAMIE AS LATEST FORECASTS INDICATE THAT IT
WILL RISE TO FLOOD STAGE TONIGHT AND PERSIST AT THAT LEVEL THROUGH
MIDDAY MONDAY.  OTHERWISE...THE GENERAL TREND IN RIVER LEVELS SLOWLY
FALLING WILL CONTINUE FOR THE UPCOMING WEEK.  MONSOONAL MOISTURE
WILL CONTINUE TO RESULT IN SCATTERED LATE DAY THUNDERSTORMS THROUGH
NEXT WEEK.  LOCALLY HEAVY RAINFALL WILL BE POSSIBLE FROM THE STORMS
ON TUESDAY AFTERNOON AND EVENING AND MAY PRODUCE BRIEF RISES IN AREA
RIVERS.
