AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
252 PM MST TUE FEB 2 2016

.SHORT TERM...(THIS EVENING THROUGH THURSDAY NIGHT)
ISSUED AT 252 PM MST TUE FEB 2 2016

SNOW HAS PRETTY MUCH TAPERED OFF TO FLURRIES ACROSS THE CWA THIS
AFTERNOON AS THE RESPONSIBLE SYSTEM CONTINUES TO MOVE AWAY FROM
THE AREA. A MINOR WAVE DROPPING SOUTHEAST ON THE BACK SIDE OF THE
MAIN UPPER LOW NOW OVER THE CENTRAL PLAINS MAY BRING SOME
ENHANCEMENT TO SNOW SHOWERS OVER MAINLY NORTHERN AND WESTERN PARTS
OF THE CWA OVERNIGHT INTO WEDS MORNING BUT NOT MUCH SNOW EXPECTED.
NEXT CONCERN WILL BE WITH WINDS THAT WILL INCREASE ON WEDS AS A
SURFACE HIGH STRENGTHENS OVER THE NEVADA/UTAH AREA AND INCREASES
THE PRESSURE GRADIENT ACROSS SE WYOMING. WITH THE RECENT GOOD
AMOUNTS OF FRESH SNOWS WILL LIKELY SEE AREAS OF BLOWING SNOW IN
THE WIND FAVORED AREAS ESPECIALLY GIVEN EXPECTED WIND GUSTS OVER
45 MPH IN THESE AREAS. WINDS SHOULD PEAK WEDS NIGHT BEFORE EASING
SLOWLY ON THURSDAY. HAVE OPTED TO POST A WINTER WEATHER ADVY FOR
BLOWING SNOW IN THE WIND FAVORED AREAS IN LIGHT OF THIS. MAINLY
DRY OTHERWISE UNTIL THURSDAY AFTERNOON WHEN THE NEXT SHORTWAVE
DROPS SOUTHEAST INTO THE AREA AND BRINGS SOME SNOW SHOWERS
THURSDAY AFTERNOON AND NIGHT.

TEMPERATURES QUITE COLD TONIGHT WITH WIND CHILLS GETTING AROUND 20
BELOW IN A FEW AREAS OVER SE WYOMING. CONTINUED COLD WEDS THEN A
LITTLE WARMER THURSDAY.

.LONG TERM...(FRIDAY THROUGH MONDAY NIGHT)
ISSUED AT 252 PM MST TUE FEB 2 2016

THE UPPER LEVEL TROUGH WILL DEPART TO THE SOUTHEAST ON
FRIDAY...WITH LINGERING SNOW SHOWERS IN THE HIGH COUNTRY IN THE
MORNING THEN DRYING THROUGH THE DAY. WINDS WILL BE ON THE BREEZY
SIDE WITH WIDESPREAD GUSTS OF 25 TO 35 MPH LIKELY ACROSS THE
FORECAST AREA. AN UPPER LEVEL RIDGE WILL MOVE OVERHEAD FOR
SATURDAY BRINING WARMER AND DRY CONDITIONS. COULD SEE TEMPS RISE
ABOVE 40 DEGREES ACROSS A GOOD MAJORITY OF THE PLAINS. WINDS WILL
INCREASE FRIDAY NIGHT IN THE WIND PRONE AREAS IN ADVANCE OF THE
NEXT CLIPPER SYSTEM APPROACHING FROM THE NORTHWEST. COULD SEE
STRONG WINDS PERSIST THROUGH EARLY SATURDAY AFTERNOON IN THESE
AREAS. DRY CONDITIONS WILL PREVAIL DURING THE DAYLIGHT HOURS ON
SATURDAY...BUT CHANCES FOR LIGHT SNOW WILL INCREASE SATURDAY NIGHT
THROUGH SUNDAY MORNING AS THE CLIPPER MOVES OVERHEAD. GUSTY WINDS
WILL PREVAIL THROUGH SATURDAY EVENING IN THE WIND PRONE
AREAS...WITH GUSTY WINDS SPREADING TO THE EAST ACROSS THE PLAINS
THROUGH SATURDAY NIGHT. NORTH-NORTHWEST FLOW WILL REMAIN OVERHEAD
IN THE WAKE OF THIS SYSTEM...MEANING TEMPS WILL STAY CHILLY
THROUGH EARLY NEXT WEEK WITH AT LEAST A SLIGHT CHANCE FOR SNOW
OVER THE AREA THROUGH MONDAY NIGHT.
