POTENT AND COMPACT TROUGH IS MOVING EASTWARD INTO NORTHWEST WY AT
2130Z. LARGE PLUME OF PAC MOISTURE EVIDENT ON SATELLITE IMAGERY IN
THE EXPANSIVE BAROCLINIC LEAF ACROSS NORTHERN WY AND ALL OF MT AT
THIS TIME. AREAS OF VORTICITY MOVING THROUGH THE BASE OF THE
LARGE-SCALE TROUGH ARE EMBEDDED IN THE SOUTHWEST FLOW ALOFT ACROSS
WY. TROUGH AXIS WILL MOVE EAST OF WESTERN WY BY 06Z SUNDAY...AND
HEAVIER SNOW WILL DIMINISH TO LIGHT SNOW SHOWERS ACROSS THE WESTERN
PORTION OF THE STATE. WINTER STORM WARNINGS FOR WESTERN WY CURRENTLY
RUN THROUGH 06Z. POWERFUL ARCTIC COLD FRONT HAS ALREADY MOVED INTO
NORTHERN NATRONA COUNTY AND SOUTHERN HOT SPRINGS COUNTY AT 22Z...AND
THE GFS AND NAM PLACE THE COLD FRONT JUST NORTH OF THE WY/CO WY/UT
BORDER BY 06Z. STRONG CONVERGENCE ALONG THE ARCTIC FRONT COMBINED
WITH A GOOD AMOUNT OF LOW LEVEL MOISTURE NEAR THE FRONT AND
OVERRUNNING MOISTURE IN SOUTHWEST FLOW ALOFT WILL PRODUCE LIGHT TO
MODERATE SNOW EAST OF THE DIVIDE. HAVE ISSUED WINTER WEATHER
ADVISORIES FOR ALL AREAS EAST OF THE DIVIDE FOR TONIGHT...EXCEPT FOR
THE WIND RIVER BASIN WHERE SNOWFALL AMOUNTS WILL BE LIMITED TO 1 TO
3 INCHES TONIGHT DUE TO THE SHADOW EFFECT FROM THE OWL CREEK AND
BRIDGER MOUNTAINS. STRONG H7 TEMPERATURES WILL FALL RAPIDLY BEHIND
THE ARCTIC FRONT TONIGHT AND WILL RANGE FROM MINUS 16 C IN SW WY TO
MINUS 26 C IN NE WY BY 12Z SUNDAY. LOWS SUNDAY MORNING WILL BE IN
THE SINGLE DIGITS ABOVE ZERO ACROSS SOUTHERN WY AND IN THE TEENS

DIVIDE SUNDAY WITH SCATTERED TO NUMEROUS SNOW SHOWERS WEST OF THE

ANOTHER STRONG UPPER LOW WILL MOVE SOUTHWARD ALONG THE WEST COAST
FROM THE PAC NW TO CENTRAL CA MONDAY AND TUESDAY. ZONAL FLOW WITH
PACKETS OF PAC MOISTURE WILL BRING PERIODS OF LIGHT SNOW TO THE
WESTERN MOUNTAINS MONDAY THROUGH TUESDAY WITH LIGHT SNOW
ACCUMULATIONS EXPECTED. IT WILL BE MAINLY DRY EAST OF THE DIVIDE
MONDAY AND TUESDAY...HOWEVER LIGHT SNOW COULD SPREAD ACROSS
SWEETWATER COUNTY MONDAY WITH A STRONGER VORTICITY MAXIMUM PROGGED
TO MOVE ACROSS SOUTHERN WY. THE MAIN WEATHER FEATURE MONDAY AND
TUESDAY WILL BE THE ARCTIC AIRMASS WHICH WILL RECEDE ONLY SLIGHTLY
TO THE NORTHEAST MONDAY AND TUESDAY. HIGHS MONDAY AND TUESDAY
ACROSS ALL OF WY WILL BE 20 TO 25 F BELOW NORMAL.

LONG TERM...TUESDAY NIGHT 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
RUN...THE PRECIPITATION AND COLD AIR IN THE SHORT TERM MAY HAVE A
SIGNIFICANT IMPACT ON THE TEMPERATURES IN THE VALLEYS AND BASINS
IN THE EXTENDED.

AVIATION...

A PACIFIC TROUGH CONTINUES TO SLIDE EAST THROUGH THE FORECAST
AREA...SPREADING SNOW SHOWERS ACROSS PORTIONS OF THE STATE. A
SECONDARY ARCTIC FRONT ALSO CONTINUES TO SLIDE SOUTH THROUGH THE
STATE...BRINGING WITH IT STRONG NORTHERLY WINDS. THESE STRONG WINDS
WILL CONTINUE THIS EVENING. SNOW SHOWERS WILL CAUSE OBSCURED
MOUNTAINS...AND WILL CAUSE PERIODS OF IFR TO LIFR CONDITIONS AT AREA
AIRPORTS. OUTSIDE OF THESE THE STRONGER SNOW BANDS...WIDESPREAD MVFR
CONDITIONS WILL BE FOUND. THE TROUGH WILL SLIDE INTO THE EASTERN
WYOMING SUNDAY AFTERNOON...WEAKENING SHOWER ACTIVITY WEST OF THE
DIVIDE AND OVER THE LOWER ELEVATIONS OF THE FORECAST AREA.

FIRE WEATHER...

HEAVY SNOWFALL ACROSS WESTERN WYOMING IS EXPECTED TO DIMINISH AROUND
MIDNIGHT...BUT LIGHT SNOW SHOWERS WILL CONTINUE ACROSS WESTERN WY
INTO EARLY SUNDAY MORNING. AN ARCTIC COLD FRONT WILL MOVE RAPIDLY
SOUTHWARD ACROSS WYOMING THIS EVENING AND BRING LIGHT TO MODERATE
SNOW TO MOST AREAS EAST OF THE DIVIDE. HEAVIER SNOWFALL TONIGHT IS
EXPECTED IN THE BIGHORN MOUNTAINS AND ON CASPER MOUNTAIN. STRONG
NORTH WINDS ALONG AND BEHIND THE ARCTIC FRONT TONIGHT WILL RANGE
FROM 25 TO 40 MPH WITH GUSTS TO AROUND 55 MPH. COLDEST AIRMASS OF
THE LATE FALL SEASON WILL SETTLE ACROSS WYOMING SUNDAY WITH HIGHS IN
THE LOW TEENS IN SOUTHERN WYOMING AND NEAR TO SLIGHTLY BELOW ZERO
