The episode as NWS RIW wrote it up.
A quick-moving clipper system in northwest flow enhanced mid-level winds which mixed to the surface during the day. These winds, along with an increased pressure gradient, produced isolated pockets of high wind east of the Continental Divide. Peak gusts between 59 and 68 mph were registered at Dubois, Crowheart, and Camp Creek RAWS in Fremont County, and at Snow Springs RAWS in Sweetwater County.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Riverton, WY wrote its last area forecast discussion before the first event at Feb 15, 3:10 AM MST, 5 hours 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RIVERTON WY 310 AM MST MON FEB 15 2016 .SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT SNOWFALL AND BLOWING SNOW WILL CONTINUE ACROSS WESTERN WYOMING AND THE CENTRAL MOUNTAINS TODAY. PERIODS OF SNOWFALL MAY BECOME MODERATE...WITH ADDITIONAL SIGNIFICANT ACCUMULATION ANTICIPATED. SNOWFALL AMOUNTS LOOK MOST PLENTIFUL OVER THE TETON MOUNTAINS...AND THE WINTER WEATHER RELATED PRODUCTS REMAIN GENERALLY IN PLACE WITH THE ADDITION OF THE BIGHORN MOUNTAINS ON THE PAST SHIFT. ANOTHER STORY ACROSS THE AREA WILL BE THE DEVELOPMENT OF STRONG WIND ACROSS PORTIONS OF THE AREA. THE FLOW ACROSS THE AREA IS A FAVORABLE FLOW PATTERN FOR VERY STRONG WIND ACROSS THE UPPER WIND RIVER BASIN AND NORTHERN JOHNSON COUNTY. ADDITIONALLY...SOME GRADIENT RELATED INFLUENCES WILL PRODUCE STRONG WIND ACROSS PORTIONS OF THE WIND CORRIDOR. MODELS IN DECENT AGREEMENT WITH THE DEVELOPMENT OF THIS STRONG WIND...SO AREAS HAVE BEEN INCLUDED IN A HIGH WIND WARNING FOR THIS AFTERNOON AND EVENING. SNOWFALL ACROSS THE AREA WILL LINGER THROUGH MUCH OF TUESDAY...MAINLY OVER THE NORTHERN MOUNTAINS. PERIODS OF GUSTY WIND WILL ALSO REMAIN OVER THE AREA. MODELS SHOWING A HINT OF SOME GAP WIND ACROSS THE CODY FOOTHILLS FOR TUESDAY NIGHT...THIS SCENARIO WILL CONTINUE TO BE MONITORED WITH UPCOMING MODEL SOLUTIONS. LINGERING SNOWFALL OVER THE NORTHWESTERN MOUNTAINS WILL CONTINUE TO TAPER OFF THURSDAY EVENING AS HIGH PRESSURE RETURNS TO THE AREA. GENERALLY DRY CONDITIONS ARE EXPECTED WEDNESDAY AFTERNOON. HOWEVER...AN APPROACHING PACIFIC WAVE WILL MOVE INLAND ON THURSDAY...AND MOISTURE FROM THIS SYSTEM WILL REACH INTO WESTERN WYOMING BY WEDNESDAY EVENING. THIS SYSTEM WILL PROVIDE SOME SNOWFALL ACROSS THE WESTERN MOUNTAINS AND POTENTIALLY THE VALLEYS. .LONG TERM...THURSDAY THROUGH MONDAY A STRONG TROUGH ALONG OR JUST OFF MUCH THE WEST COAST WEDNESDAY NIGHT IS EXPECTED TO SWING QUICKLY EAST/NORTHEAST AND BECOME NEGATIVELY TILTED AS IT CROSSES THE ROCKIES THURSDAY/THURSDAY EVENING. THIS SYSTEM WILL HAVE DUEL THREAT...WITH SIGNIFICANT SNOW ESPECIALLY IN THE WESTERN MOUNTAINS...AND STRONG TO HIGH WIND EVENT ESPECIALLY IN THE WIND CORRIDOR BETWEEN ROCK SPRINGS AND CASPER...BUT OTHER AREAS WILL NEED TO BE WATCHED. ON THE WIND SIDE...PROJECTED 700MB SW FLOW OF 50-60KT...A TIGHTENING SURFACE PRESSURE GRADIENT AS THE LEE TROUGH QUICKLY INTENSIFIES...ALONG WITH STEEP LAPSE RATES...AND SOME RIGHT FRONT QUAD DYNAMICS SUGGEST HIGH WIND WARNING CRITERIA WILL BE MET IN THE ROCK SPRINGS TO CASPER AREA THURSDAY. ALSO IF THE STRENGTH AND ORIENTATION OF THE JET STREAK IS CORRECT THE LANDER FOOTHILLS WILL NEED TO BE WATCHED FOR HIGH WIND LATE WEDNESDAY NIGHT INTO THURSDAY MORNING. THEN AS THE STRONG PACIFIC COLD FRONT PUSHES WEST TO EAST ACROSS THE FORECAST AREAS...OTHER SPOTS SUCH AS THE DUBOIS TO CROWHEART WILL NEED TO BE MONITORED FOR HIGH WIND...BUT THIS CONFIDENCE IS NOT AS HIGH. FOR THE SNOW SIDE...PRECIPITATION SHOULD BE ONGOING OR BECOMING MORE WIDESPREAD ACROSS THE WEST AT 12Z THURSDAY. A MOIST SOUTHWEST FLOW...COUPLED WITH STRONG QG FORCING AND OVERALL SYNOPTIC LIFT ASSOCIATED WITH THIS NEGATIVELY TILTED TROUGH SHOULD RESULT IN WIDESPREAD PRECIPITATION ALONG AND AHEAD OF THE COLD FRONT THURSDAY AFTERNOON. THE MAJORITY OF PRECIPITATION OVER THE WEST SHOULD END RELATIVELY QUICKLY BETWEEN 21Z THURSDAY AND 03Z FRIDAY. MODELS ARE SHOWING POCKETS OF SLIGHTLY NEGATIVE LIFTED INDICES AND STEEP LAPSE RATES...WHICH IN COMBINATION WITH THIS SYSTEM SHOULD RESULT IN SOME THUNDER. THE COMBINATION OF SNOW AND WIND WILL LIKELY RESULT IN SOME WINTER HIGHLIGHTS FOR THE WESTERN MOUNTAINS. VALLEYS WILL BE TRICKIER WITH ENOUGH WARM AIR AHEAD OF THE FRONT WHERE PRECIPITATION WILL BE A COMBO OF RAIN AND SNOW. RIGHT NOW IT APPEARS THE SNOW VS RAIN WILL RANGE BETWEEN 6000 AND 7500 KFT MSL THURSDAY MORNING...WITH A QUICK CHANGE OVER TO SNOW IN THE LOWER ELEVATIONS IN WAKE OF THE FRONT. EAST OF THE DIVIDE...PRECIPITATION WILL BE MUCH MORE LIMITED...BUT WHERE ANY CONVECTION CAN FORM...A THREAT OF SOME STRONG TO HIGH WINDS MIXING DOWN WILL BE A CONCERN. A WEAKER SYSTEM IS THEN EXPECTED IN THE FRIDAY NIGHT INTO SATURDAY TIME FRAME...WITH THE BEST SHOT AT PRECIPITATION OVER THE WEST SATURDAY MORNING BASED ON CURRENT TIMING...WITH THE TYPICAL WINDY AREAS EAST OF THE DIVIDE. DEPENDING UPON YOUR MODEL PREFERENCE COULD SEE MARGINAL HIGH WIND IN THE CODY FOOTHILLS FRIDAY NIGHT/SATURDAY MORNING. MAINLY DRY CONDITIONS ARE EXPECTED IN WAKE OF THIS SYSTEM SUNDAY. MODELS THEN DIFFER IN THE HANDLING OF A SYSTEM PUSHING THROUGH A RIDGE OVER THE WEST COAST...AND THEN ACROSS THE NORTHERN/CENTRAL ROCKIES MONDAY. THE ECWMF WEAKENS THIS SYSTEM AND IS A BIT SLOWER THAN THE GFS. WILL ONLY HAVE SOME SLIGHT MOUNTAIN POPS FOR THIS SYSTEM UNTIL THERE IS A MORE CONSENSUS. TEMPERATURES THROUGH THE EXTENDED WILL CONTINUE TO BE ABOVE TO WELL ABOVE AVERAGE FOR FEBRUARY. && .AVIATION.../12Z ISSUANCE/ WEST OF THE DIVIDE...KJAC/KRKS/KPNA/KBPI ROUTES A STRONG AND MOIST WESTERLY FLOW WILL RESULT IN AREAS OF LLWS AND WIDESPREAD MTN OBSCURATIONS IN SN THROUGH THE MORNING. AREAS OF MVFR/IFR -SN WILL INCREASE ACROSS THE WESTERN VALLEYS...KJAC-KAFO- KEMM THROUGH THE MORNING HOURS AND CONTINUE THROUGH THE AFTERNOON...POSSIBLY BECOMING MIXED WITH RAIN BELOW 7KFT. OCNL MVFR CIGS AND VSBY IN -SN MAY ALSO AFFECT KPNA-KRKS THROUGH 18Z. STRONG WEST TO NORTHWEST WINDS ALOFT WILL PUSH DOWN TO THE SFC...20-30KT WITH GUST TO 35-40KT 14Z-18Z MONDAY ACROSS THE UPPER GREEN RIVER BASIN (KPNA-KBPI) AND INTERSTATE 80 CORRIDOR. SOUTH WIND WILL INCREASE THROUGH THE JACKSON VALLEY WITH LLWS CONTINUING THROUGH THE AFTERNOON. WINDS WILL DIMINISH MONDAY EVENING WITH DECREASING SHSN COVERAGE ACROSS THE WESTERN MTNS AND FAR WEST VALLEYS...HOWEVER AREAS OF MVFR...LCL IFR CIGS WILL LIKELY PERSIST THROUGH TUESDAY MORNING VCNTY KJAC-KAFO-KEMM. EAST OF THE DIVIDE...KCPR/KCOD/KRIW/KWRL/KLND ROUTES STRONG NORTHWEST WIND ALOFT WILL RESULT IN AREAS OF LLWS ACROSS MUCH OF THE AREA THROUGH MONDAY MORNING. THESE STRONGER WINDS WILL MIX DOWN TO THE SFC 16Z-19Z MONDAY. THE BIGHORN RANGE AND THE DIVIDE WILL REMAIN MOSTLY OBSCD THROUGH MONDAY EVENING. A CLIPPER SYSTEM DIVING DOWN INTO THE NORTHERN HIGH PLAINS ON MONDAY COULD BRING A BAND OF IFR/MVFR SHSN INTO EAST CENTRAL WYOMING LATE MONDAY AFTERNOON AND MONDAY EVENING...MAINLY VCNTY KSHR-KBYG BUT THE BAND MAY REACH AS FAR SOUTH AS KCPR MONDAY EVENING. THIS SHOULD BE ANOTHER QUICK-HITTING BAND OF SHSN WITH BRIEF MVFR/IFR CONDITIONS LASTING NO MORE THAN AN HOUR OR TWO. WINDS WILL DIMINISH MOST AREAS 03Z-6Z MONDAY...HOWEVER HIGH WINDS WITH SFC GUSTS OVER 50KTS MAY DEVELOP ALONG THE CODY FOOTHILLS ALONG WITH SOME MOUNTAIN WAVE ACTIVITY 8Z-12Z TUESDAY. && .FIRE WEATHER... PERIODS OF HEAVY SNOW WILL REMAIN ACROSS MUCH OF WESTERN WYOMING TODAY WITH CONTINUED WINTER WEATHER HIGHLIGHTS. ADDITIONALLY...AREAS OF VERY STRONG WIND ARE ANTICIPATED ACROSS PORTIONS OF CENTRAL AND SOUTHERN WYOMING.
