.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. THE 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

THROUGH SATURDAY EVENING IN THE WIND PRONE AREAS...WITH GUSTY
WINDS SPREADING TO THE EAST ACROSS THE PLAINS THROUGH SATURDAY
