SLOPE OF THE CODY FOOTHILLS LATER TONIGHT WITH THE LCL WRF SHOWING
POTENTIAL FOR WAVE BREAKING FOR A VERY BRIEF PERIOD LATE TONIGHT.
BASED ON ALL THIS...HAVE ISSUED A HIGH WIND WATCH FOR THE CODY
FOOTHILLS AREA. MOST LIKELY AREA WILL BE OUR GAP FAVORED AREAS
SOUTHWEST AND SOUTH OF CODY AND NEAR THE MOUTH OF THE CLARKS FORK
CANYON.

SATL LOOP INDICATING A STRATUS DECK OVER FAR WESTERN
WY...PRIMARILY OVER THE STAR AND JACKSON VALLEYS AND PORTIONS OF
YELLOWSTONE PARK. THIS IS THE EASTERN EXTENSION OF A BROAD AREA OF
STRATUS THAT EXTENDS WEST ALONG THE SNAKE RIVER PLAIN TO BOISE AND
EASTERN OREGON UNDERNEATH THE SURFACE HIGH. THERE IS ALSO EVIDENCE
OF WHAT IS PROBABLY PATCHY FOG OVER SOUTH PASS AND PORTIONS OF
SWEETWATER COUNTY AND THE SOUTHERN UPPER GREEN RIVER BASIN. THE
STRATUS IS PROBABLY MAKING CONTACT WITH THE VALLEY FLOOR OVER
SOUTHERN LINCOLN COUNTY WHERE THE ELEVATIONS ARE CLOSER TO 7K.
HAVE MENTION OF PATCHY FOG IN THESE AREAS THROUGH 18Z BUT JUST
HAVE MENTION OF CLOUDS ACROSS THE WESTERN VALLEYS AND YNP.

THE INVERSIONS WILL WEAKEN BY THIS EVENING AS A STRONG VIGOROUS
SHORTWAVE TRAILING FROM A STRONG VORT OVER SE ALASKA SWEEPS EAST
SOUTHEAST TOWARD WY AND INCREASES THE PRESSURE GRADIENT. A
WESTERLY DIFFLUENT FLOW WILL STRENGTHEN ALONG WITH SOME Q VECTOR
FORCING WHICH WILL RESULT IN A QUICK SHOT OF SNOWFALL IN NORTHWEST
WY TUESDAY....HOWEVER AMOUNTS WILL BE RATHER LIGHT. THE SURFACE
PRESSURE GRADIENT IS PROGGED TO BE 20 MB BETWEEN RKS AND GCC
TUESDAY. THIS COUPLED WITH 31KT WINDS FORECAST IN THE NAM MOS

ACROSS AREAS EAST OF THE DIVIDE TUESDAY EVENING. 700MB WINDS WILL
BE NORTHWEST AT 50 MPH IN JOHNSON COUNTY DURING THIS TIME FRAME.
THIS FAVORABLE UPSLOPE WIND SHOULD PRODUCE ONE TO TWO INCHES OF
FLUFFY SNOWFALL FROM THE EAST SLOPES OF THE WINDS AND THE LANDER
FOOTHILLS TO CASPER TUESDAY NIGHT. HOWEVER HAVE TRENDED MOST OF
THE SNOWFALL TO OCCUR EAST TOWARD CASPER ALONG WITH SOME BLOWING

-24C BY 12Z WED. WIND CHILLS OF 25 BELOW WILL BE FAIRLY COMMON BY
TUESDAY NIGHT EAST OF THE DIVIDE WITH LOWS DROPPING TO ZERO TO 10
BELOW ALONG WITH THE STRONG POST FRONTAL WINDS. FUTURE SHIFTS MAY WANT
TO CONSIDER A SNOW ADVISORY FOR TUESDAY EVENING IN THESE AREAS.
THIS COLD FRONT WILL LEAD TO A PATTERN CHANGE WITH PRIMARILY NW
FLOW AND TWO CLIPPER TYPE SYSTEMS BRINGING LIGHT SNOW TO THE
NORTHERN MTNS WED THROUGH WED NIGHT ALONG WITH COLDER TEMPS
EVERYWHERE WITH MANY AREAS NOT GETTING ABOVE THE TEENS WEDNESDAY.
TEMPS SHOULD REACH 15 TO 20 BELOW IN THE UPPER GREEN RIVER BASIN
WED NT.

LONG TERM...THURSDAY THROUGH MONDAY
THURSDAY AND FRIDAY WILL BE DOMINATED BY NORTHWEST FLOW ACROSS THE
AREA...WITH STRONG RIDGING ALONG 135W AND A LONGWAVE TROUGH ACROSS
THE EASTERN HALF OF THE COUNTRY.  THIS FLOW WILL BE CONDUCIVE FOR
LIGHT TO MODERATE OROGRAPHIC SNOW...ESPECIALLY ACROSS THE NORTHERN
MOUNTAINS.  IN ADDITION...A WEAK CLIPPER SYSTEM IS EXPECTED TO
AFFECT THE AREA LATE THURSDAY INTO THURSDAY NIGHT...BRINGING A
SLIGHT REINFORCEMENT OF COLD AIR INTO THE AREA...AND ENHANCING THE
SNOW...ESPECIALLY ACROSS THE BIGHORN MTS...WHERE SEVERAL INCHES OF
SNOW COULD OCCUR. THE NORTHWEST FLOW WILL CONTINUE FOR THE REMAINDER
OF THE EXTENDED...WITH A DECENT SHORTWAVE TROUGH AFFECTING THE AREA
SATURDAY NIGHT THROUGH MONDAY TIME FRAME...WITH THE 00Z GFS MORE
PROGRESSIVE AND FASTER THAN THE 00Z ECMWF.  HAVE BROAD BRUSHED POPS
DUE TO TIMING ISSUES...BUT HIT SUNDAY AND SUNDAY NIGHT THE HARDEST
RIGHT NOW.  THE COLD FRONT ASSOCIATED WITH THIS TROUGH...WILL BRING
YET ANOTHER REINFORCING SHOT OF COLD AIR.  THUS...BELOW AVERAGE
TEMPERATURES ARE EXPECTED TO CONTINUE FOR THE EXTENDED TIME FRAME.
SATURDAY COULD BE THE CLOSEST DAY TO NORMAL...AHEAD OF THE COLD
FRONT SUNDAY/SUNDAY NIGHT.
