AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
1040 AM MST THU JAN 2 2014

.SHORT TERM...THURSDAY THROUGH SATURDAY NIGHT

CERTAINLY A MUCH QUIETER NIGHT IN OUR HUMBLE WEATHER ABODE THIS
MORNING THAN YESTERDAY MORNING AS THE COUNTY WARNING AREA IS
PRECIPITATION FREE AT THIS POINT. THAT WILL BE THE RULE FOR MOST
AREAS WITH A DRY NORTHWEST FLOW PATTERN FOR MOST AREAS TODAY. WE CAN
NOT RULE OUT A FEW FLURRIES OR LIGHT SNOW SHOWERS IN THE
NORTHWESTERN MOUNTAINS BUT THESE SHOULD BE INCONSEQUENTIAL. IT LOOKS
TO BE A DRY WITH A MIXTURE OF SUNSHINE AND MID TO HIGH LEVEL CLOUDS.
THERE WILL BE SOME PATCHY FOG THIS MORNING WITH THE FRESH SNOW COVER
AROUND. ALSO...THERE WILL BE GUSTY WINDS IN THE USUAL SPOTS LIKE THE
SOUTHWESTERN WIND CORRIDOR AS WELL AS THE CODY HILLS AND ESPECIALLY
AROUND EVERYONE'S FAVORITE CROSSROAD...CLARK.

THE NEXT WEATHER MAKER WILL BEGIN TO APPROACH THE AREA LATER
TONIGHT. THE 6Z NAM HAS COME INTO BETTER AGREEMENT WITH THE OTHER
MODELS IS SLOWING THE ARRIVAL OF THE STEADIER PRECIPITATION IN THE
WEST UNTIL FRIDAY MORNING SO WE CUT POPS AND QPF JUST A BIT FOR THE
OVERNIGHT PERIOD. THE OTHER CONCERN IS FOR THE POTENTIAL FOR HIGH
WINDS FOR THE CODY FOOTHILLS AND ESPECIALLY YOU GUESSED IT...CLARK.
A GOOD THERMAL GRADIENT DOES DEVELOP TONIGHT AND 700 MILLIBAR WINDS
ARE PROGGED TO INCREASE TO 55 TO 60 KNOTS. AS A RESULT...WE WILL
ISSUE A HIGH WIND WATCH FOR LATER TONIGHT AND INTO TOMORROW. MAINLY
QUIET WEATHER IS ANTICIPATED EAST OF THE DIVIDE TONIGHT.

STEADIER PRECIPITATION THEN SPREADS INTO NORTHWESTERN WYOMING AS THE
TROUGH ARRIVES AND BETTER JET ENERGY SPREADS INTO THE AREA. AT THIS
TIME...IT LOOKS MORE LIKE ADVISORY LEVEL SNOW SINCE THE STEADIEST
SNOW WILL LIKELY BE SHORT LIVED. MEANWHILE...EXPECT A DRY DAY FOR
MOST AREAS EAST OF THE DIVIDE. IT COULD ALSO BE A WARMER DAY WITH
THE TIGHTENING PRESSURE GRADIENT FROM THE FRONT INCREASING MIXING
AND DOWNSLOPING FLOW OFF OF THE MOUNTAIN RANGES. IT COULD GET QUITE
WINDY ACROSS THE SOUTHWESTERN WIND CORRIDOR AS WELL. THE FRONT THEN
DROPS SOUTHWARD ACROSS AREAS EAST OF THE DIVIDE FRIDAY NIGHT AND
WILL LIKELY BRING A PERIOD OF SNOW. HOW MUCH IS STILL UP IN THE AIR.
HOWEVER SEEING HOW A FEW OF THE RECENT SYSTEMS IN THE NORTHWEST FLOW
PATTERN HAVE OVERACHIEVED COMPARED TO WHAT THE MODELS HAVE BEEN
SHOWING THERE COULD BE A FEW INCHES OF SNOW. SATURDAY WILL BE A
COLDER DAY...AS MUCH AS 20 TO 25 DEGREES COLDER THAN FRIDAY WITH
NORTHWEST FLOW CONTINUING. THE GFS SHOWS A SECOND PIECE OF ENERGY
MOVING INTO THE AREA WHILE THE NAM IS DRIER AND KEEPS ANY SNOW
SHOWERS OVER NORTHEASTERN WYOMING. FOR NOW WE KEPT POPS IN FOR THE
MORNING WITH DRIER CONDITIONS IN THE AFTERNOON BUT UNCERTAINTY IS
HIGH AT THIS POINT.

.LONG TERM...SUNDAY THROUGH THURSDAY

SIDING MORE AND MORE WITH THE ECMWF TONIGHT AS IT HAS BEEN MOST
CONSISTENT AND LOOKING MORE AND MORE LIKE IT'S JUST GOING TO BE
RIGHT WITH OUR ARCTIC OUTBREAK AND TIMING. THE AIRMASS ALREADY
LOOKS QUITE COLD AHEAD OF THE ARCTIC COLD FRONTAL ARRIVAL AS
AIRMASS BEHIND THE FRIDAY NIGHT AND SATURDAY SYSTEMS ARE VERY COLD.
SO IT LOOKS LIKE A COLD START TO THE DAY ALREADY WITH THE ARCTIC
COLD FRONT ARRIVING IN THE NORTH BY THE START OF THIS PERIOD OR
SOONER AND THEN DROPPING QUICKLY SOUTH THROUGH ALL AREAS EAST OF
THE DIVIDE DURING THE DAY. TEMPERATURES WILL HOLD OR DROP DURING
THE DAY IN THE FAR NORTH...PROBABLY DROP AS COLD AS THIS AIRMASS
IS TO THE NORTH...AND THEN FURTHER SOUTH HIGHS WILL BE MET IN THE
MORNING WITH FALLING READINGS THE REST OF THE DAY. GFS SEEMS WAY
TOO DRY WITH THIS SYSTEM WHILE THE ECMWF AND GEM SHOW WIDESPREAD
LIGHT SNOW. I CONTINUE TO KEEP CHANCE POPS IN ACROSS THE AREA ON
SUNDAY AS THE MODEL ALLBLEND IS JUST TOO DRY. BITTERLY COLD MONDAY
MORNING WITH -5 TO -15 QUITE COMMON IN ALL BUT THE SOUTH. SOME
LOWER CLOUDS MAY HELP SOME AREAS FROM EVEN GETTING COLDER WHERE
SHALLOW UPSLOPE CONTINUES. THE ARCTIC AIRMASS WILL LIKELY BE SLOW
TO LEAVE ON MONDAY SO CONTINUING TO SIDE CLOSER TO THE COLDER ECMWF.
THE GFS PUSHES THE AIRMASS QUICKLY EWD MONDAY WITH A DRAMATIC
WARMUP. PROBABLY NOT TOO LIKELY AS THERE IS A SECONDARY SHORTWAVE
THAT DROPS DOWN SUNDAY NIGHT TO REINFORCE THE SURFACE HIGH TO THE
NORTH. THIS SHORTWAVE SHOULD HELP TO KEEP A SECOND BITTERLY COLD
DAY IN FOR MONDAY EAST OF THE DIVIDE BEFORE IMPROVEMENT. PATTERN
DOES START TO SHIFT QUICKLY OFF TO THE EAST THOUGH MONDAY NIGHT
INTO TUESDAY WITH RIDGE WEAKENING AND MOVING OVERHEAD AHEAD OF THE
NEXT SHORTWAVE MOVING IN FROM THE WEST TUESDAY INTO TUESDAY NIGHT
WITH A CHANCE OF SNOW MAINLY OUT WEST. WEAK SHORTWAVE RIDING IS
FORECAST FOR LATER WEDNESDAY INTO WEDNESDAY NIGHT WITH SOME LIGHT
ISENTROPIC UPGLIDE SNOW OUT WEST. ANOTHER SPLITTING SHORTWAVE FROM
THE WEST ON THURSDAY WILL LIKELY LEAD TO CONTINUED LIGHT SNOW OUT
WEST. TEMPERATURES WILL MODERATE WITH INCREASED CLOUD COVER TO
TEMPER OVERNIGHT LOWS AND JUST OVERALL MILDER PACIFIC AIR COVERING
THE AREA.
