AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
1007 PM MST MON FEB 17 2014

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY NIGHT)
ISSUED AT 300 PM MST MON FEB 17 2014

WINDS CONTINUE TO BE THE MAIN FORECAST CHALLENGE AT LEAST INTO
TOMORROW AFTERNOON. MODELS HAVE SEVER ELY STRUGGLED IN THE CURRENT
WEATHER PATTERN MAKING FOR LOWER FORECAST CONFIDENCE THAN NORMAL.
VERY FAST UPPER LEVEL FLOW WITH SEVERAL DISTURBANCES WHICH ARE
TOUGH TO RESOLVE ARE THE MAIN CULPRITS. THIS PATTERN IS NOT SEE TO
CHANGE ANYTIME SOON...MAKING FOR CHALLENGING FORECASTS.

THAT SAID...NAM AND GFS ARE INDICATING WINDS WILL REMAIN ELEVATED
ACROSS PORTIONS OF SOUTHEAST WYOMING THE NEXT 24 HOURS. STRONG
SUBSIDENCE WHICH LED TO STRONG WINDS IN THE CHEYENNE AREA THIS
MORNING HAS RETREATED BUT BASED ON MODELS...SUBSIDENCE WILL
REDEVELOP TOWARD SUNRISE TUESDAY. 700 MB QG SUBSIDENCE IS VERY
IMPRESSIVE AFTER SUNRISE. A CORE OF STRONG WINDS WILL DEVELOP OVER
THE NORTHERN CWA LATER TONIGHT AND THEN SHIFT SOUTHWARD ALONG WITH
COOLING TEMPERATURES ALOFT. THERE COULD BE ENOUGH COOLING IN THE
MID LEVELS PRODUCE STEEP LAPSE RATES FROM THE SURFACE TO NEAR 700
MB. THE QUESTION IS IF A SHALLOW LOW LEVEL INVERSION WILL HOLD. IF
NOT...HIGH WINDS MAY DEVELOP OVER MUCH OF THE CWA LATE
TONIGHT...INCLUDING RAWLINS...DOUGLAS...AND LARAMIE. OF COURSE MOS
GUIDANCE LESS THAN IMPRESSIVE WITH WIND SPEEDS.

FOR NOW KEPT THE HIGH WIND WARNING GOING FOR THE WIND PRONE AREAS
AND MUCH OF LARAMIE AND PLATTE COUNTIES INTO TUESDAY AFTERNOON.
CURRENTLY WINDS ARE BELOW THRESHOLDS EVERYWHERE BUT WINDS ARE
CLOSE IN SOME PLACES AND SHOULD REACCELERATE LATE TONIGHT INTO
TUESDAY MORNING. CHEYENNE SHOULD SEE A NEAR REPEAT PERFORMANCE OF
WINDS THIS MORNING...COME TUESDAY MORNING. STRONG SUBSIDENCE AND
COLD ADVECTION SHOULD BE THE MAIN DRIVER OF WINDS EAST OF THE
LARAMIE RANGE AND WILL HAVE TO KEEP AN EYE ON WINDS AS FAR EAST AS
THE NEBRASKA PANHANDLE LATE TONIGHT THROUGH TUESDAY MORNING AS
WELL. DID NOT ISSUE A WIND ADVISORY FOR THE PANHANDLE GIVEN POOR
MODEL PERFORMANCE MORE THAN SEVERAL HOURS OUT BUT IF THE 00Z
MODELS KEEP THE STRONG WINDS GOING...VERY WELL MAY NEED AN
ADVISORY AND A HIGH WIND WARNING IS NOT OUT OF THE QUESTION IF
THINGS COME TOGETHER JUST RIGHT. JUST LIKE IN SOUTHEAST WYOMING...
MOS GUIDANCE WINDS ARE BELOW ADVISORY SPEEDS NEARLY
EVERYWHERE...ALTHOUGH THE GFS MOS GETS CLOSE FOR A BRIEF PERIOD.

MOST OF THE NEXT SEVERAL DAYS WILL BE DRY BUT ANOTHER SHORTWAVE
TROUGH IS PROGGED TO MOVE ACROSS THE AREA LATE WEDNESDAY. THIS
SYSTEM WILL LIKELY BRING ANOTHER QUICK SHOT OF RAIN AND SNOW. DOES
NOT LOOK LIKE A HEADLINES WILL BE NEEDED BUT THE MOUNTAINS SHOULD
SEE A FEW INCHES OF SNOW. BASED ON CURRENT TIMING VERY WELL COULD
SEE ANOTHER ROUND OF THUNDER WITH SOME OF THE RAIN/SNOW SHOWERS.

.LONG TERM...(THURSDAY THROUGH MONDAY)
ISSUED AT 300 PM MST MON FEB 17 2014

COOLER CONDITIONS THURSDAY BEHIND DEPARTING UPPER TROF WITH JUST
SOME LINGERING SNOW SHOWERS EXPECTED OVER THE HIGHER MTNS. NW FLOW
ALOFT WILL THEN PREVAIL OVER THE AREA THROUGH THE WEEKEND WITH A
COUPLE OF SHORTWAVES PASSING ACROSS BRINGING COOLER SHOTS OF AIR
AND SOME SNOW SHOWERS...AGAIN MAINLY OVER THE MTNS. PATTERN GETS A
BIT MORE INTERESTING EARLY NEXT WEEK AS A PUSH OF COLDER AIR OUT
OF CANADA IS PROGGED TO SINK DOWN INTO THE REGION AND BE
OVERRUN BY THE MOIST WNW UPPER FLOW. SHOULD SEE AN UPTICK IN
SNOW COVERAGE OVER THE CWA AS WELL AS COLDER CONDITIONS IF THIS
MATERIALIZES.  STILL A WAYS OUT BUT WILL WATCH WITH INTEREST.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z TUESDAY EVENING)
ISSUED AT 1005 PM MST MON FEB 17 2014

VFR CONDITIONS EXPECTED THE NEXT 24 HOURS AND BEYOND WITH NEXT
CHANCE FOR LOWERING CONDITIONS WEDNESDAY. WINDS WILL BE THE MAIN
CONCERNS WITH WIND GUSTS TO 40KTS POSSIBLE AT KLAR AND KRWL AFTER
15Z OR SO...PERSISTING THROUGH 00Z.

&&

.FIRE WEATHER...
ISSUED AT 419 AM MST MON FEB 17 2014

MILD AND WINDY CONDITIONS WILL CONTINUE ACROSS THE DISTRICT TODAY
AND TUESDAY. MANY AREAS ACROSS SOUTHEAST WYOMING WILL SEE WIND
GUSTS OF 40 TO 60 MPH TODAY. WINDS WILL DECREASE SOME FOR
TUESDAY...WITH THE NEXT COLD FRONTAL PASSAGE DUE IN WEDNESDAY
AFTERNOON/EVENING. THIS WILL BRING THE NEXT CHANCE FOR
PRECIPITATION TO THE REGION. HIGH TEMPERATURES WILL REACH THE 40S
WEST OF THE LARAMIE RANGE AND 50S EAST THROUGH WEDNESDAY. AS A
RESULT...WILL SEE MINIMUM RELATIVE HUMIDITIES FALL INTO THE
20S...WITH EVEN SOME TEENS IN THE IMMEDIATE LEE OF THE LARAMIE
RANGE TODAY. THESE WILL INCH UP AHEAD OF THE NEXT SYSTEM TUESDAY
AND WEDNESDAY.
