A quick-moving trough that clipped northern Utah brought briefly strong winds to some locations along Utah's northern border.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

NWS Salt Lake City, UT wrote its last area forecast discussion before the first event at Nov 17, 7:40 PM MST, 7 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SALT LAKE CITY UT 740 PM MST TUE NOV 17 2015 .SYNOPSIS...HIGH PRESSURE ALOFT WILL MOVE EAST ACROSS UTAH TONIGHT...FOLLOWED BY A MOIST NORTHWEST FLOW IMPACTING NORTHERN AND WESTERN UTAH THROUGH THE END OF THE WEEK. && .DISCUSSION...WATER VAPOR LOOP SHOWS RIDGING BUILDING IN BEHIND THE LAST STORM SYSTEM. THE NEXT SYSTEM IS MOVING INTO BRITISH COLUMBIA. AMDAR 400- 250MB WIND OBSERVATIONS PLACES A 125KT-150KT ANTICYCLONIC JET FROM BRITISH COLUMBIA INTO THE CENTRAL ROCKIES. GOES/HRRR/GPS/00Z SLC RAOB INDICATE THE PRECIPITABLE WATER VALUE RANGES BETWEEN 0.15"- 0.25" MOUNTAINS...TO 0.35"-0.50" MOST VALLEYS. RAP 850-700MB THICKNESS/SATURATED EQUIVALENT POTENTIAL TEMPERATURE/STREAMLINES INDICATE A WARM FRONT WILL CROSS THE AREA OVERNIGHT AHEAD OF TOMORROWS COOL FRONT. THE INCREASING WARM ADVECTION ALONG WITH THE ARRIVAL OF THE NOSE OF THE UPPER LEVEL JET BY MORNING SHOULD RESULT IN A GENERAL INCREASE IN THE THREAT OF LIGHT PRECIPITATION ACROSS THE NORTH...PRIMARILY IN THE MOUNTAINS WHERE BUFKIT FORECAST SOUNDINGS INDICATE PART OF THE TIME MOISTURE SHOULD BE SHALLOW ENOUGH TO BE MORE SUPPORTIVE OF RIME ICING. WITH THE ARRIVAL OF THE JET...RIDGETOP WINDS LOOKS TO CONTINUE TO INCREASE TOWARD MORNING. TEMPERATURES SHOULD STEADY OR SLOWLY RISE ESPECIALLY UNDER CLOUD COVER AND IN SNOWPACK VOID AREAS. && .PREVIOUS DISCUSSION FOLLOWS... THE AXIS OF THE POSITIVE-TILT UPPER RIDGE CURRENTLY OVER NORTHWEST UTAH WILL CONTINUE ACROSS THE STATE TONIGHT. BEHIND THE RIDGE A STRONG AND GENERALLY MOIST WEST-NORTHWEST FLOW ALOFT WILL EXIST THROUGH THE END OF THE WEEK. THE MID TO LATE WEEK PERIOD WILL BE DOMINATED BY A SERIES OF FAST- MOVING SHORTWAVES EMBEDDED TO THE NORTHWEST FLOW ACROSS THE NORTHERN ROCKIES/NORTHERN GREAT BASIN. THE FIRST WAVE IMPACTING NORTHERN UTAH THIS AFTERNOON HAS PRODUCED AN EXTENSIVE LOW CLOUD FIELD FROM THE MOIST LOW-LEVEL ADVECTION AHEAD OF THIS FEATURE. INSUFFICIENT DYNAMIC LIFT AND DEEP LAYER MOISTURE WILL LIMIT ANY LIGHT PRECIP TO THE NORTHERN MOUNTAINS AND ADJACENT WINDWARD VALLEYS OVERNIGHT. SUBSTANTIAL LOW-LEVEL COLD ADVECTION TRAILING THE SHORTWAVE EARLY WEDNESDAY MAY GENERATE ADDITIONAL PRECIP... THOUGH THIS TOO WILL BE ON THE LIGHT SIDE AND CONFINED TO THE AREA OF STRONGEST COLD ADVECTION. WIND WILL LIKELY BE AN ISSUE ACROSS FAR NORTHERN UTAH/SOUTHWEST WYOMING BEHIND THE SURFACE COLD FRONT. THE SURFACE GRADIENT WILL SUPPORT GUSTY WEST-NORTHWEST WINDS... WITH POTENTIAL FOR STRONG WINDS DUE TO DOWNWARD MOMENTUM TRANSFER FROM THE NEAR 700MB 40-50 KNOT WINDS ACROSS NORTHERN UTAH/SOUTHWEST WYOMING. THIS COULD TURN INTO AN ADVISORY-LEVEL EVENT FOR THE FAR NORTH BY LATE WEDNESDAY MORNING/AFTERNOON. BOTH THE ECMWF AND GFS GRADUALLY EVOLVE THE PATTERN INTO A CYCLONIC WEST-NORTHWEST FLOW ACROSS THE GREAT BASIN BY LATE IN THE WEEK. THIS TRANSITION SIGNALS INCREASING DYNAMIC AND THERMAL SUPPORT FOR MORE SIGNIFICANT LIFT AND A BROADER AREA OF PRECIP ACROSS THE NORTH. THE PROLONGED PERIOD OF SNOW ACROSS THE NORTHERN MOUNTAINS THROUGH FRIDAY COMBINED WITH FAVORABLE FLOW INTO THE TERRAIN AND INCREASED SYNOPTIC-SCALE LIFT COULD LEAD TO A DECENT AMOUNT OF SNOW FOR THE NORTHERN WASATCH RANGE. POINTS SOUTH AND EAST OF FAR NORTHERN UTAH WILL LIKELY SEE SIGNIFICANTLY LESS PRECIP...WITH GENERALLY DRY CONDITIONS CONTINUING ACROSS THE SOUTHERN HALF OF THE STATE. MODELS SHOW WEAK SHORT WAVE RIDGING ADVANCING INTO THE GREAT BASIN AT THE START OF THE LONG TERM PERIOD. THE NEW 12Z EC SLOWLY AMPLIFIES THIS RIDGE AND SHIFTS IT EAST THRU OUR CWA OVER THE WEEKEND THEN EAST OF THE AREA MON. THE 12Z GFS HAD A WEAK SHORT WAVE TROF SLIDING ACROSS THE NRN CWA ON SAT/SAT NIGHT BUT HAS MOVED TOWARDS THE EC WITH A MUCH WEAKER FEATURE IN THE NEW 18Z RUN AND HAVE PRETTY MUCH REMOVED POPS FROM THE GRIDS FOR THIS TIME FRAME AND HAVE KEPT THE FORECAST DRY THROUGH MON. MODELS HAD BEEN DIGGING A COLD TROF INTO THE WESTERN STATES TOWARDS THE MIDDLE OF NEXT WEEK BUT APPEAR TO BE TRENDING TOWARDS A SOLUTION THAT DIGS THE LOW EITHER DOWN THE WEST COAST OR EVEN SOMEWHAT OFFSHORE. THIS KEEPS THE REGION UNDER A MILD AND MOSTLY SWLY FLOW THRU AT LEAST TUE. THIS TREND TOWARDS A CLOSED LOW OVER OR NEAR THE WEST COAST IMPLIES A SLOWER EWD PROGRESSION BUT ALSO ADDS UNCERTAINTY AS TO WHERE OR HOW SIGNIFICANT ANY TRAVEL IMPACTS WILL BE AS WE START TO APPROACH THANKSGIVING TRAVEL TIME. && .AVIATION...CEILINGS AT THE SLC TERMINAL SHOULD GENERALLY REMAIN BELOW 7000FT THROUGH AT LEAST 18Z WEDNESDAY...WITH ANY CIGS ABOVE THAT LEVEL LIKELY TO BE SHORT-LIVED. THERE IS ALSO A CHANCE THAT CEILINGS COULD OCCASIONALLY DROP TO MVFR LEVELS...WITH A MOST LIKELY TIME FRAME OF 12Z TO 18Z. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...NONE.
