WHITEOUT CONDITIONS IN BLOWING AND DRIFTING SNOW. IMPACT TO TRAVEL
THROUGH NATRONA AND JOHNSON COUNTIES EXPECTED TO BE SIGNIFICANT
TONIGHT. INTRODUCED ISOLATED SNOW SHOWERS TO THE WIND RIVER BASIN
LATE THIS MORNING AND DURING THE EARLY AFTERNOON AS STRONG
INSTABILITY JUST AHEAD OF THE SURFACE COLD FRONT WILL ALLOW SOME
SHOWERS TO MOVE OFF OF THE WIND RIVER MOUNTAINS AND OUT INTO THE
BASIN. ARCTIC FRONT ALREADY INTO NORTHERN MONTANA EARLY THIS

BIG HORN BASIN DURING THE MORNING...THEN PLOW THROUGH JOHNSON COUNTY

NORTH TO NORTHEAST WIND AND DANGEROUS WIND CHILL VALUES.

PACIFIC MOISTURE MOVING OUT AHEAD OF ANOTHER CLOSED LOW DIGGING
SOUTHWARD ALONG THE PACIFIC NORTHWEST COAST IN THE LONG-WAVE
TROUGH OVER THE WESTERN U.S. WILL PRODUCE PERIODS OF LIGHT SNOW
OVER WESTERN AND CENTRAL WYOMING SUNDAY THROUGH MONDAY NIGHT.
SIGNIFICANT SNOWFALL IS NOT ANTICIPATED BUT ANY SNOW THAT DOES
FALL WILL ACCUMULATE WITH THE FRIGID TEMPERATURES AND MAKE FOR
SLICK ROADWAYS THROUGHOUT THE CWA...ALONG WITH AREAS OF BLOWING
AND DRIFTING SNOW. WIND CHILL MAY BECOME A CONCERN OVER THE NORTH
SUNDAY MORNING WITH MODERATE NORTH WIND CONTINUING AND POSSIBLY
PRODUCING WIND CHILL VALUES BELOW -30F.

LONG TERM...TUESDAY THROUGH FRIDAY
EXTENDED MODELS HAVE THEIR PROBLEMS WITH AMOUNT OF PRECIPITATION AND
COLD AIR OVER THE AREA TUESDAY THROUGH FRIDAY. IGNORED MUCH OF THE
BIAS CORRECTED FORECAST GUIDANCE AS PAST WARMER TEMPERATURES
LIKELY WARMING UP BIAS CORRECTED DATA TOO MUCH. OVERALL COMPLEX
LONG WAVE TROUGH DEEPENS OVER THE WESTERN U.S. WITH SERIES OF
NORTHERN PUSHES FOLLOWED BY SOUTHWEST FLOW AS LOWS CUT OFF OVER
EASTERN PACIFIC OFF SOUTHERN CAL. THEN RETURN OF NORTHERLY
TROUGHS. FLOW OSCILLATES FROM NORTHERLY TO SOUTHWEST THROUGH THE
PERIOD MAKING FORECAST VERY DIFFICULT AND PRODUCES VERY LOW
CONFIDENCE IN THE FORECAST. BIG CHALLENGE KEEPING TEMPERATURES
MATCHED UP WITH THE SURROUNDING FORECASTS WITH OFFICES TO THE WEST
AND SOUTH ON THE WARM SIDE AND THOSE TO THE NORTH AND EAST ON THE
COLD SIDE WITH WESTERN AND CENTRAL WYOMING IN BETWEEN. LOW
CONFIDENCE SCATTERED POPS MAINLY IN THE WESTERN AND NORTHERN
MOUNTAINS BUT THERE IS A THREAT OF PRECIPITATION EACH DAY
DEPENDING ON TIMING AND ORIENTATION OF THE FLOW ALOFT. IN THE LONG

SIGNIFICANT IMPACT ON THE TEMPERATURES IN THE VALLEYS AND BASINS
IN THE EXTENDED.
