THE FLOOD WATCH FOR A PORTION OF SOUTH CENTRAL WYOMING HAS BEEN
CANCELLED. 

SLIGHT COOLER TEMPERATURES ARE EXPECTED ON FRIDAY...WITH BELOW
NORMAL TEMPERATURES EXPECTED THIS WEEKEND. THERE IS EVEN A CHANCE
OF SNOW ABOVE 7000 FEET AS A COOL PACIFIC SYSTEM PUSHES ACROSS THE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
408 AM MDT WED MAY 25 2011

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT...
THE UPPER LOW WAS OVER CENTRAL KANSAS EARLY THIS MORNING AND WILL
CONTINUE TO MOVE EAST TODAY.  MOST OF THE SHOWERS ENDED OVER THE
RECENTLY.  THE EXCEPTION WAS AT 09Z WHERE SOME SHOWERS PERSISTED
UNDER THE ENHANCED CLOUD BAND OVER CENTRAL AND SOUTH CENTRAL
WYOMING.  WITH FORECAST ISSUANCE WILL GO AHEAD AND CANCEL THE
FLASH FLOOD WATCH THAT WAS IN EFFECT FOR THE SOUTHERN PANHANDLE.
THE ABUNDANT LOW LEVEL MOISTURE OVER THE EAST PART OF THE CWA WILL
PRODUCE LOW CLOUDS AND AREAS OF FOG THROUGH THE MID MORNING.  THE
ATMOSPHERE WILL DRY SOME TODAY...HOWEVER THERE SHOULD BE ENOUGH
MOISTURE AND WEAK LIFT TO KEEP SOME SHOWERS GOING THROUGH THE EARLY
EVENING.  THE LIFT WILL BE PROVIDED BY MID LEVEL CONVERGENCE OVER
THE CWA AND CHANNELED VORTICITY.  THE CURRENT CLOUD BAND MAY
ACTUALLY SLOWLY SHIFT EAST THROUGH THE EARLY EVENING.  HEIGHTS ALOFT
INCREASE OVER THE CWA THIS AFTERNOON AND TONIGHT WITH THE RIDGE AXIS
MOVING EAST OF THE CWA SHORTLY AFTER 12Z THURSDAY.  SURFACE HIGH
PRESSURE WILL ALSO BUILD OVER THE REGION TONIGHT AND THURSDAY
MORNING.  THE RESULT WILL BE DRY WEATHER DURING THAT TIME.  THE
UPPER LOW CURRENTLYJUST OFF THE PACIFIC NORTHWEST COAST WILL THEN
MOVE EAST AND FILL.  BY 12Z FRIDAY THE FEATURE WILL BE OVER CENTRAL
OR WESTERN MONTANA.  THE ASSOCIATED SURFACE COLD FRONT WILL MOVE
ACROSS THE CWA THURSDAY AFTERNOON THROUGH EARLY FRIDAY MORNING.
THE FLOW ALOFT WILL BE DIFFLUENT THURSDAY AFTERNOON AND EARLY
THURSDAY NIGHT OVER THE CWA WITH FAVORABLE JET DYNAMICS.  ALSO...
AHEAD OF THE FRONT THE LOW LEVEL MOISTURE WILL INCREASE.  AT LEAST
A SCATTERED COVERAGE OF THUNDERSTORMS WILL DEVELOP ALONG AND AHEAD
OF THE FRONT THURSDAY AFTERNONO AND THURSDAY NIGHT.  SOME OF THE
STORMS WILL BE STRONG OVER THE EAST PART OF THE CWA.  THE ACTIVITY
WILL SHIFT EAST THURSDAY NIGHT AND WEAKEN.  BEHIND THE FRONT WILL
BE DRIER AIR AND STRONG WEST OR NORTHWEST SURFACE WINDS.  THE
TEMPERATURES WILL BE AROUND NORMAL THROUGH 12Z FRIDAY.

.LONG TERM...FRIDAY THROUGH WEDNESDAY FRIDAY-FRIDAY NIGHT:
LATEST WATER VAPOR LOOP WAS SHOWING A VIGOROUS POTENTIAL VORTICITY
(PV) ANOMALY ROTATING JUST OFF THE PACIFIC NORTHWEST STATES. THIS
FEATURE IS PROGGED TO PUSH EAST INTO THE ROCKIES. AS THIS PV ANOMALY
MOVES INTO MONTANA ON FRIDAY...DRY CONDITIONS WILL PREVAIL OVER THE
AREA DUE TO GOOD DOWNSLOPE FLOW. IN ADDITION...IT WILL BE QUITE
WINDY AS WELL WITH THE INFLUENCE OF SUBSIDENCE FROM THE PV ANOMALY
AND THE RIGHT EXIT REGION OF THE UPPER LEVEL JET. AT THIS POINT...IT
APPEARS LIKE THE BULK OF THE HIGHER CHINOOK WINDS WILL BE ALONG THE
EASTERN CORRIDOR OF THE LARAMIE RANGE. AS A RESULT...WE KEPT WIND
SPEEDS BOOSTED DURING THE OVERNIGHT TIMEFRAME. TEMPERATURES DURING
THIS TIME WILL BE NEAR NORMAL WITH HIGHS IN THE 60S EAST OF THE
LARAMIE RANGE WITH MAINLY 50S WEST AND 30S AND 40S IN THE MOUNTAINS.

SATURDAY-SUNDAY:
THIS PERIOD WILL BE QUITE TRICKY ESPECIALLY WITH REGARDS TO
TEMPERATURES AND THE POSITION OF THE FRONTAL BOUNDARY. LATEST WATER
VAPOR LOOP WAS SHOWING THE NEXT WAVE CURRENTLY SPINNING AROUND 47
DEG N AND 155 DEG W WITH ABOUT 170KT JET AT THE BASE OF THIS WAVE.
THE MODELS ARE PROGGING THIS WAVE TO MOVE TOWARDS NEVADA AROUND 12Z
ON SUNDAY. AHEAD OF THIS FEATURE...THE MODELS ARE ALSO DEPICTING
SOME PIECES OF ENERGY QUICKLY PUSHING NORTHEAST INTO THE NORTHERN
PLAINS SATURDAY AND SATURDAY NIGHT. DURING THE PAST COUPLE OF
RUNS...THE MODELS ARE DEVELOPING A STATIONARY FRONTAL BOUNDARY NEAR
THE WY/CO BORDER. IF THIS PIECE OF ENERGY CAN CREATE A SUFFICIENT
GRADIENT ALONG THE BOUNDARY IT MAY PRODUCE SOME SCATTERED SHOWERS
AND ISOLATED THUNDERSTORMS ALONG IT. THIS MAY ALSO CREATE MUCH
COOLER CONDITIONS COMPARED TO PREVIOUS RUNS. THE MODELS ARE IN
PRETTY GOOD AGREEMENT OF THIS OCCURRING. HOWEVER...I AM NOT OVERLY
OPTIMISTIC THAT THIS BOUNDARY WILL BE VERY WELL ESTABLISHED ON
SATURDAY. WE HAVE KEPT TEMPERATURES FAIRLY CONSISTENT WITH THE
PREVIOUS FORECAST FOR NOW WHICH IS WARMER THAN THE CONSENSUS MODELS.
WE HAVE ALSO BUMPED UP POPS A BIT FROM THE PREVIOUS FORECAST FOR
AREAS MAINLY ON THE SOUTHERN HALF OF THE FORECAST AREA.

THE MODELS ARE SHOWING A BIT MORE CONSISTENCY WITH THE MAIN PV
ANOMALY MOVING INTO EXTREME WESTERN WYOMING BY 12Z MONDAY. THE ECMWF
IS THE SLOWEST. AS THIS WAVE APPROACHES...THE STATIONARY FRONTAL
BOUNDARY WILL BEGIN LIFTING NORTH AS A WARM FRONT ACROSS THE
FORECAST AREA WHICH WILL CAUSE THE CHANCE OF SHOWERS AND
THUNDERSTORMS TO INCREASE ON SUNDAY INTO SUNDAY NIGHT. WE HAVE
BUMPED UP POPS DURING THIS TIMEFRAME...AND COOLED TEMPERATURES OFF A
BIT MAINLY ON SUNDAY AS THE GRADIENT INCREASES ALONG THE FRONTAL
BOUNDARY.

MONDAY-WEDNESDAY:
THINGS ARE STILL LOOKING INTERESTING FOR MONDAY AS THE NEGATIVELY
TILTED UPPER LEVEL WAVE MOVES TOWARDS THE NORTHERN PLAINS. THE ECMWF
IS STILL THE SLOWEST IN MOVING THIS FEATURE ACROSS. IF THIS SYSTEM
DOES MOVE A LITTLE SLOWER THAN IT MAY BE ABLE TO DRAW MORE MOISTURE
TO AREAS EAST OF THE LARAMIE RANGE. THIS MAY HELP IGNITE SOME STRONG
AFTERNOON THUNDERSTORMS IN THE NEBRASKA PANHANDLE ALONG AND EAST OF
THE FRONTAL BOUNDARY. AFTER THE FRONT MOVES ACROSS THE REGION MONDAY
NIGHT...IT APPEARS LIKE THE UPPER LEVEL RIDGE WILL FINALLY BUILD
OVER THE REGION AND BRING MILDER AND DRY CONDITIONS BY MIDWEEK.
&&

.AVIATION...12Z TAF ISSUANCE...
MVFR OR IFR CEILINGS WILL BE WIDESPREAD OVER MAINLY THE NORTH SND
EAST PARTS OF THE CWA THROUGH MID MORNING.  AREAS OF MVFR
VISIBILITIES IN FOG CAN ALSO BE EXPECTED OVER THAT AREA THROUGH 15Z
DESPITE THE BRISK NORTHERLY WINDS.  VFR CONDITIONS WILL THEN BE OVER
THE CWA THROUGH EARLY TONIGHT.  SOME SHOWERS AND THUNDERSTORMS WILL
BE OVER THE EAST PART OF THE CWA BY MIDDAY AND CONTINUE THROUGH THE
EARLY EVENING.  MVFR CEILINGS AND VISIBILITIES IN FOG WILL REDEVELOP
OVER THE EAST PART OF THE CWA AFTER 06Z TONIGHT AND CONTINUE THROUGH
15Z THURSDAY IN THE MOIST SOUTHEAST BOUNDARY LAYER WIND FLOW.
THUNDERSTORMS WILL FORM THURSDAY AFTERNOON AND THEN WEAKEN AND END
FROM WEST TO EAST THURSDAY NIGHT.  SOME OF THE STORMS WILL BE STRONG
WITH BRIEF MVFR CEILINGS AND VISIBILITIES IN RAIN ASSOCIATED.
SOUTHERLY SURFACE WINDS WILL GUST AS HIGH AS 40 KNOTS ON THURSDAY.
THEN WESTERLY WINDS WILL SPREAD EAST OVER THE CWA BEHIND THE FRONT
LATE THURSDAY AFTERNOON AND THURSDAY NIGHT WITH GUSTS AS HIGH AS 45
KNOTS.

&&

.FIRE WEATHER...
NO FIRE WEATHER CONCERNS AT THIS TIME DUE TO FIRE DANGER IN THE LOW
CATEGORY AND RECENT AND PREDICTED PRECIPITATION OVER THE AREA.

&&

.HYDROLOGY...
THE SIGNIFICANT RAINFALL ENDED OVER THE EAST PART OF THE CWA BY 08Z.
DOPPLER ESTIMATES AND GROUND TRUTH INDICATED BETWEEN 1 AND 2 INCHES
OF RAIN FELL OVER MANY AREAS IN THE PANHANDLE AND NEARBY SOUTHEAST
WYOMING TUESDAY AFTERNONO AND EVENING.  THAT RAINFALL CAUSED STREAMS
AND RIVERS IN THE AREA TO RISE.  THE MOST SIGNIFICANT PERHAPS WAS ON
THE NORTH PLATTE AT MITCHELL...WHERE WATER LEVELS ROSE ALMOST A FOOT
IN A SHORT TIME.  THE RISE HAS ENDED BETWEEN 06Z AND 09Z AND THE
GAGE AT MITCHELL WAS READING 9.0 FEET.  WATER LEVELS IN STREAMS IN
RIVERS OVER THE EAST PART OF THE CWA WILL DECREASE TODAY.  THE FLOOD
WARNING CONTINUES FOR THE NORTH PLATTE BETWEEN HENRY AND MITCHELL.

RIVERS AND STREAMS ACROSS THE WYOMING PART OF THE CWA WILL CONTINUE
TO RISE DUE TO THE RECENT PRECIPITATION AND MOUNTAIN SNOW MELT.
MANY RIVERS ARE OR WILL BE AT BANKFULL OR FLOOD STAGE BY THE END
OF THE WEEK OR THIS WEEKEND.  THE LARAMIE RIVER WILL BE THE LAST
TO REACH THOSE LEVELS.  THE FLOOD WARNING FOR THE LITTLE SNAKE RIVER
ENDS THIS EVENING AND MAY NEED TO BE EXTENDED.  THE FLOOD WATCH FOR
THE UPPER NORTH PLATTE ALSO CONTINUES THROUGH FRIDAY.  ADDITIONAL
WATCHES AND WARNINGS MAY BE NEEDED FOR THE RIVERS AND STREAMS
FLOWING OFF OF THE SIERRA MADRE AND SNOWY RANGES BY THE END OF THE
WEEK.  MORE RAIN LOOKS TO BE UPCOMING NOW OVER THE WEEKEND...WITH
WARMER TEMPERATURES BY THE MIDDLE OF NEXT WEEK.
