AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
408 AM MST SUN NOV 9 2014
.SHORT TERM...(TODAY THROUGH MONDAY NIGHT)
ISSUED AT 408 AM MST SUN NOV 9 2014
THE LAST MILD DAY OVER THE CWA FOR SOME TIME WILL OCCUR TODAY AS
WNW FLOW ALOFT CONTINUES WITH VARYING AMOUNTS OF HIGH CLOUDINESS.
MAX TEMPS WILL REACH THE 60S TO EVEN AROUND 70 OVER MOST LOWER
ELEVATIONS TODAY. FIRST CONCERN WILL BE THE WINDS WHICH ARE STILL
EXPECTED TO INCREASE THIS AFTERNOON AS SURFACE PRESSURE FALLS OVER
THE HIGH PLAINS OCCUR IN RESPONSE TO AN APPROACHING SHORTWAVE...
RESULTING IN A STEEP GRADIENT ACROSS SOUTHEASTERN WYOMING. THE
USUAL WIND-PRONE AREAS LOOK A SOLID BET FOR HIGH WINDS THROUGH
TONIGHT. CONSIDERED AREAS SUCH AS THE LARAMIE VALLEY AND THE
NORTH LARAMIE RANGE BUT WINDS HERE LOOK A BIT LESS AND OMEGA
FIELDS NOT AS SUPPORTIVE BUT THE WINDS MAY GET CLOSE.
THE STRONG WINDS WILL COME TO AN END MONDAY MORNING AS A STRONG
COLD FRONT DROPS SOUTH ACROSS THE CWA BRINGING MUCH COLDER AIR.
HIGHS FOR THE DAY WILL BE ATTAINED IN THE MORNING WITH
TEMPERATURES FALLING THROUGH THE DAY...REACHING THE TEENS IN MANY
AREAS BY EVENING. FAVORABLE UPPER JET POSITION COMBINING WITH LIFT
SHOULD ALLOW A DECENT AMOUNT OF SNOW TO FALL OVER NORTHERN PARTS
OF THE CWA LATER MONDAY MORNING THROUGH THE AFTERNOON WITH SEVERAL
INCHES LOOKING A GOOD BET. GIVEN THIS ALONG WITH GUSTY NORTHERLY
WINDS HAVE OPTED TO POST A WINTER WEATHER ADVY FOR CONVERSE AND
NIOBRARA COUNTIES FOR MONDAY.
TEMPERATURES WILL CONTINUE TO DROP MONDAY NIGHT BUT SNOW SHOULD
TAPER OFF TO MOSTLY FLURRIES ACROSS THE CWA AS SUPPORT WEAKENS.
TEMPS WILL FALL INTO THE SINGLE DIGITS OVER MANY AREAS BY EARLY
TUESDAY MORNING.
.LONG TERM...(TUESDAY THROUGH SATURDAY)
ISSUED AT 408 AM MST SUN NOV 9 2014
THE DRASTIC CHANGE IN THE AIRMASS WHICH HITS SOUTHEAST WYOMING AND
THE NEBRASKA PANHANDLE MONDAY IS NOT EXPECTED TO RELENT THROUGH
THIS WEEK. TEMPERATURE WILL BE WELL BELOW NORMAL THIS WEEK WITH
THE FIRST SUBZERO LOW TEMPERATURES OF THE SEASON FOR MUCH OF THE
AREA. WEDNESDAY NIGHT COULD SEE TEMPERATURES 10 BELOW ZERO OR
COLDER ACROSS NORTHERN PORTIONS OF THE AREA DEPENDING ON CLOUD
AND SNOW COVER.
ALONG WITH THE MUCH COLDER TEMPERATURES THIS WEEK WILL BE SEVERAL
CHANCES FOR LIGHT SNOW. THE UPPER LEVEL JET WILL GENERALLY BE
LOCATED OVER THE AREA THROUGH THIS WEEK PROVIDING UPPER LEVEL
LIFT. THERE WILL ALSO BE A FEW WEAK UPPER DISTURBANCES THAT WILL
INTERACT WITH A MIDLEVEL COLD FRONT. AT THIS TIME NOT EXPECTING
ANY BIG SNOW MAKERS BUT SHOULD SEE SEVERAL INCHES OF SNOW ACROSS
THE HIGHER MOUNTAINS. LOWER ELEVATIONS OF SOUTHEAST WYOMING COULD
SEE A FEW INCHES OF SNOW IN SOME PLACES DEPENDING ON STRENGTH AND
LOCATION OF UPPER LEVEL ENERGY...BUT UNLIKELY FOR ANY SIGNIFICANT
ACCUMULATIONS THROUGH FRIDAY.

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z SUNDAY NIGHT)
ISSUED AT 408 AM MST SUN NOV 9 2014
MAIN AVIATION CONCERN THROUGH THE TAF PERIOD WILL BE THE WINDS.
THE STRONGEST WINDS WILL BE FOUND ACROSS WIND PRONE PORTIONS OF
SOUTHEAST WYOMING...INCLUDING THE ARLINGTON AREA AND THE SOUTHERN
LARAMIE RANGE/FOOTHILLS. WINDS ARE ALREADY GUSTING 40 TO 50 MPH IN
THESE AREA THIS MORNING AND WILL INCREASE THIS AFTERNOON INTO THE
EVENING HOURS WITH GUSTS IN EXCESS OF 60 MPH AT TIMES. WINDS WILL
BEGIN TO SUBSIDE LATE SUNDAY NIGHT AS A COLD FRONT PUSHES INTO THE
AREA...BRINGING WITH IS COLD ARCTIC AIR. BREEZY NORTH WINDS MONDAY
WITH SNOW DEVELOPING AND SPREADING SOUTHWARDS THROUGH THE DAY.
MOUNTAINS WILL BECOME OBSCURED MONDAY DUE TO FALLING SNOW.

.FIRE WEATHER...
ISSUED AT 408 AM MST SUN NOV 9 2014
WINDS WILL BE GUSTY AROUND THE MOUNTAINS TODAY AND BE QUITE STRONG
OVERNIGHT ESPECIALLY IN WIND-PRONE AREAS. LOWEST HUMIDITIES WILL
APPROACH 20 PER CENT THIS AFTERNOON OVER THE PLAINS. CONCERNS WILL
THEN BE VERY LOW FOR THE UPCOMING WEEK AS A STRONG COLD FRONT
BRINGS IN MUCH COLDER AIR MONDAY WITH SOME LIGHT SNOWS. COLD
TEMPERATURES WILL THEN HOLD FOR THE WEEK.
