Area forecast discussion, Dec 7, 11:41 AM MST, 2 hours 13 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
1141 AM MST MON DEC 7 2015
.UPDATE...
ISSUED AT 1130 AM MST MON DEC 7 2015
STILL EXPECTING GUSTS OF 55-65 MPH TO CONTINUE IN THE WIND PRONE
AREAS THROUGH THE EARLY EVENING AS THE CAG-CPR GRADIENT REMAINS
AROUND 60 METERS. HAVE SEEN A FEW GUSTS NEAR 50 KTS AT CYS...BUT
SOUNDINGS SHOWS WINDS ALOFT DECREASING THROUGH 00Z...SO WILL HOLD
OFF ON ISSUING HIGH WIND WARNING FOR THIS AFTN.
&&
.SHORT TERM...(TODAY-TUESDAY NIGHT)
ISSUED AT 317 AM MST MON DEC 7 2015
MAIN FORECAST CHALLENGES REVOLVE AROUND THE POTENTIAL FOR HIGH WINDS
ACROSS SOUTHEAST WY AND THE WESTERN NE PANHANDLE. WYDOT OBSERVATIONS
ARE FINALLY STARTING TO HIT WARNING CRITERIA IN THE WIND PRONE AREAS
INCLUDING ARL/BRX/VDW WITH A FEW GUSTS AROUND 60 MPH. ADDED BORDEAUX
TO THE INHERITED WARNING STARTING IMMEDIATELY. NAM 850 MILLIBAR CAG-
CPR HEIGHT GRADIENTS REMAIN AT OR ABOVE 50 METERS THROUGH THE ENTIRE
PERIOD...PEAKING AROUND 70 METERS BETWEEN 00Z-09Z TUE. H7-H8 FLOW IS
EXPECTED TO REMAIN BETWEEN 50-60 KNOTS OVER THE WIND CORRIDORS TODAY
ALONG WITH SUBSIDENCE BEHIND A FAST-MOVING SHORTWAVE NOW MOVING EAST
ACROSS CENTRAL NE. AS SUCH...WINDS SHOULD BE NEAR OR ABOVE HIGH WIND
WARNING CRITERIA TODAY THROUGH TUE AM WITH THE STRONGEST WIND LIKELY
OCCURRING LATE TONIGHT WHEN H75 WINDS INCREASE ABOVE 60 KTS AFTER 3Z
TONIGHT. MOUNTAIN WAVE ACTIVITY CAUSED A BRIEF PERIOD OF STRONG WIND
AT COLEMAN IN PLATTE COUNTY LAST EVENING. PARAMETERS ONLY GET BETTER
WITH TIME...SO ADDED THAT ZONE TO THE WARNING. EARLIER NAM SOUNDINGS
FROM DOUGLAS SHOWED A WELL MIXED PROFILE WITH 50+ KNOTS NEAR THE SFC
BETWEEN 18Z-00Z. ISSUED A WARNING BASED ON THIS...HOWEVER THE LATEST
IR SATELLITE LOOP HAS SHOWN A RATHER DRAMATIC INCREASE IN HIGH CLOUD
ACROSS EASTERN WY IN THE LAST HOUR. THIS WILL PROBABLY IMPACT MIXING
POTENTIAL DEPENDING ON CLOUD THICKNESS...SO CONFIDENCE IS DECREASING
FOR THAT ZONE.
WE ARE STILL LOOKING AT THE POTENTIAL FOR WINDS TO SPREAD INTO PARTS
OF THE HIGH PLAINS LATE TONIGHT. A POTENT MID-LEVEL SHORTWAVE TROUGH
WILL MOVE RAPIDLY ACROSS NORTHEAST WY TONIGHT W/EXCELLENT SUBSIDENCE
IN THE EXIT REGION OF A 120+ KT H25. NAM AND GFS ARE IN AGREEMENT W/
STRONG DOWNWARD OMEGA SPREADING ALONG THE I-80 CORRIDOR BETWEEN CYS-
IBM OVERNIGHT. SOUNDINGS SHOW 50 TO 60 KT WINDS WITHIN AN IMPRESSIVE
SUBSIDENCE INVERSION...SO CONFIDENCE IS HIGH ENOUGH TO GO AHEAD WITH
A HIGH WIND WATCH FARTHER EAST. THIS MAY BE A SHORT DURATION...BORA-
TYPE EVENT FOR THE PLAINS. BIG DIFFERENCES IN WIND PROFILES FROM THE
NAM AND GFS LATER IN THE DAY ON TUE. THE NAM SHOWS MUCH WEAKER WINDS
ALOFT OWING TO A MORE MODEST GRADIENT COURTESY OF THE NORTHERN TRACK
OF THE AFOREMENTIONED WAVE. GFS AND ECM HANG ON TO 50+ KTS OF 750 MB
FLOW WELL INTO THE AFTERNOON...SO THIS BRINGS INTO QUESTION JUST HOW
STRONG THE MIXING EVENT WILL BE LATER IN THE DAY. MAV GUIDANCE SHOWS
30-35 KT SUSTAINED WINDS FROM CYS-SNY...AND NORTH TO BFF. THE MET IS
MUCH LESS BULLISH. WENT AHEAD WITH A TEMPORAL EXTENTION OF THE WATCH
UNTIL 21Z...JUST IN CASE. WINDS ACROSS THE WHOLE CWA SHOULD DIMINISH
SOMEWHAT INTO TUE EVENING AS GRADIENTS WEAKEN...BUT WARNING-CRITERIA
WINDS WILL RETURN TO THE WIND CORRIDORS BY EARLY WEDNESDAY AM AS THE
H85 CAG-CPR GRADIENT INCREASES TO 60 METERS AT 12Z.
WARM TEMPERATURES ARE EXPECTED OVER THE NEXT FEW DAYS WITH LOW-LEVEL
DOWNSLOPE FLOW IN PLACE ALONG/E OF THE LARAMIE RANGE. VERY LITTLE IN
THE WAY OF PRECIPITATION IS EXPECTED WITH LARGE SCALE SUBSIDENCE AND
VERY MEAGER MOISTURE PROFILES. MAY SEE AN INCH OR TWO OF SNOW IN THE
SNOWIES AND SIERRA MADRES LATE TONIGHT THROUGH TUE IN ASSOCIATION W/
THE NEXT WAVE...BUT DO NOT EXPECT ANYTHING OUTSIDE OF THE
MOUNTAINS.
.LONG TERM...(WEDNESDAY THROUGH SUNDAY NIGHT)
ISSUED AT 400 AM MST MON DEC 7 2015
STRONG GUSTY WINDS WILL BE THE PRIMARY FORECAST CONCERN THROUGH
THE MIDDLE OF THIS WEEK WITH MODELS IN REASONABLE AGREEMENT. BY
NEXT WEEKEND...COLDER TEMPERATURES AND A HIGHER CHANCE OF SNOWFALL
APPEARS MORE LIKELY. HOWEVER...MODELS ARE IN POOR AGREEMENT PAST
FRIDAY.
MODELS GENERALLY REMAIN DRY THROUGH THURSDAY AFTERNOON. WHILE ALL
MODELS ARE GENERALLY NOT PRODUCING PRECIP...CAN NOT RULE OUT SOME
SNOW INTO THE MOUNTAINS...PARTICULARLY THE SNOWY AND SIERRA MADRE
RANGES WEDNESDAY AND WEDNESDAY NIGHT AS A FAST MOVING UPPER LEVEL
SHORTWAVE MOVES ACROSS MONTANA AND NRN WYOMING. STRONG WESTERLY
UPSLOPE FLOW FOR THE MOUNTAINS IS CONDUCIVE OF ACCUMULATING SNOW
EVEN IF A LITTLE BIT OF MOISTURE SNEAKS ACROSS THE PACIFIC
NORTHWEST AND INTO THE FORECAST AREA. EAST OF THE LARAMIE
RANGE...POP IS BELOW 10 PERCENT SINCE IT IS VERY UNLIKELY ANY
PRECIP WILL REACH THE SURFACE DUE TO DOWNSLOPE WINDS.
EXPECT WINDY CONDITIONS ACROSS MOST OF SOUTHEAST WYOMING WEDNESDAY
AND THURSDAY...BUT LOCALLY STRONG WINDS WITH GUSTS AROUND 60 MPH
ARE POSSIBLE OVER THE WIND PRONE AREAS INTO EARLY THURSDAY MORNING
AS A SURFACE LOW TRACKS EASTWARD OVER MONTANA AND THE NORTHERN
PLAINS. THE BEST CHANCE FOR STRONG GUSTY WINDS WILL BE LATE
WEDNESDAY THROUGH EARLY THURSDAY MORNING AS A STRONG 150KT JET MAX
MOVES INTO WYOMING ALONG WITH RAPIDLY DECREASING SURFACE PRESSURE
ACROSS THE HIGH PLAINS AS A COLD FRONT MOVES ACROSS THE REGION. THIS
COULD BE A HYBRID BORA/MIXING EVENT AS A QUICK SHOT OF COOL AIR
MOVES ACROSS THE AREA IN ASSOCIATION WITH A PASSING SHORTWAVE.
KEPT WINDS ON THE HIGH SIDE...ESPECIALLY ACROSS SOUTHEAST WYOMING
WITH HIGH WIND CRITERIA LIKELY OVER THE WIND PRONE AREAS OF I80
AND I25...AND HIGH WIND CRITERIA POSSIBLE NEAR
CHEYENNE...LARAMIE...AND FURTHER NORTH BETWEEN DOUGLAS AND
TORRINGTON THROUGH THURSDAY MORNING. WINDS ARE EXPECTED TO
GRADUALLY SUBSIDE THROUGH FRIDAY...BUT PERIODS OF WINDY OR VERY
WINDY CONDITIONS ARE STILL EXPECTED ALONG AND WEST OF I25.
MODELS GENERALLY SHOW PRECIP CHANCES INCREASING BY FRIDAY...BUT
WITH CONSIDERABLE TIMING DIFFERENCES KEPT POP BETWEEN 15 TO 25
PERCENT OUTSIDE OF THE MOUNTAINS. IT WILL BE NOTICEABLY COLDER
HOWEVER...WITH HIGHS STRUGGLING TO REACH 35 TO 45 DEGREES ON
FRIDAY. DEPENDING ON THE TIMING OF THE FRONT...HIGH TEMPERATURES
MAY OCCUR IN THE MORNING WITH RAPIDLY LOWERING TEMPERATURES DURING
THE AFTERNOON. FOR THE WEEKEND...DID NOT CHANGE THE PREVIOUS
FORECAST TOO MUCH SINCE MODELS ARE IN POOR AGREEMENT WITH THE
ECMWF SHOWING A BROAD TROUGH AND STORM SYSTEM DEVELOPING ACROSS
THE FOUR CORNERS REGION LATE FRIDAY AND INTO SATURDAY WITH
WIDESPREAD SNOWFALL ACROSS THE I80 CORRIDOR. IN CONTRAST...THE
GFS SHOWS THIS ENERGY MUCH FURTHER NORTH WITH GENERALLY DRY
NORTHWEST FLOW ACROSS WYOMING AND WESTERN NEBRASKA FOR THE
WEEKEND. OVERALL...IT APPEARS A MORE ACTIVE WEATHER PATTERN IS IN
STORE FOR THE FRONT RANGE PAST NEXT WEEKEND.
&&
.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON)
ISSUED AT 1117 AM MST MON DEC 7 2015
SOUTHEAST WINDS WILL REMAIN VERY STRONG ACROSS THE WIND PRONE
PORTIONS OF SOUTHEAST WYOMING TODAY...TONIGHT...AND THROUGH MOST
OF THIS WEEK. FREQUENT GUSTS OF 50 TO 60 MPH WILL OCCUR ACROSS
THESE AREAS. THIS INCLUDES ACROSS THE SOUTHERN LARAMIE RANGE AND
NEAR BY FOOTHILLS...AND ALSO THE NORTHERN SNOWY RANGE FOOTHILLS
INCLUDING ARLINGTON AND AND ELK MOUNTAIN. STRONG WINDS WILL
SPREAD INTO THE PLAINS TONIGHT. WINDS MAY ALSO SPREAD INTO THE
NEBRASKA PANHANDLE WHERE GUSTS TO 50 MPH ARE POSSIBLE LATE
TONIGHT.
&&
.FIRE WEATHER...
ISSUED AT 317 AM MST MON DEC 7 2015
VERY STRONG WINDS WILL OCCUR TODAY AND TONIGHT OVER THE TYPICAL WIND
PRONE LOCATIONS OF SOUTHEAST WYOMING. WIND GUSTS OF 65 TO 75 MPH ARE
POSSIBLE. THESE WINDS MAY SPREAD INTO THE ADJACENT HIGH PLAINS LATER
TONIGHT THROUGH EARLY TUE MORNING. WINDS SHOULD REMAIN ELEVATED OVER
MUCH OF THE AREA THROUGH MIDWEEK. WHILE MINOR SNOWFALL ACCUMULATIONS
ARE EXPECTED IN THE MOUNTAINS TONIGHT...WARM AND DRY CONDITIONS WILL
PERSIST ELSEWHERE OVER THE NEXT FEW DAYS. RH VALUES WILL REMAIN WELL
OUTSIDE OF CRITICAL THRESHOLDS.
