AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
1120 AM MDT TUE MAY 6 2014

.SHORT TERM...TUESDAY THROUGH THURSDAY NIGHT

SOME PRECIPITATION IS ONGOING RIGHT NOW WITH SOME SHOWERS MAINLY
OVER THE ABSAROKAS IN RESPONSE TO SOME UPPER LEVEL DIVERGENCE WITH
THE RIGHT REAR QUAD OF THE JET MOVING BY. THINGS ARE STILL FAIRLY
WARM WITH FREEZING LEVELS GENERALLY AROUND 8000 FEET.

ACTIVE WEATHER WILL CONTINUE TODAY AS A COLDER AIR OOZES INTO THE
AREA AND A TROUGH POTENTIAL CLOSES OFF JUST TO THE EAST OF THE
ABSAROKAS. THIS WOULD BRING STEADY PRECIPITATION TO THE ABSAROKAS.
THE MODELS HAVE SOME DIFFERENCES IN THE PLACEMENT OF THE HEAVIER
PRECIPITATION THOUGH. FOR NOW...CONTINUITY LOOKED REASONABLE WITH
REGARDS TO QPF IN THE NORTHWEST SO WE LEFT CONTINUITY ALONE. AS FOR
PRECIPITATION TYPE...MODELS STILL HAVE SOME SLIGHT DIFFERENCES WITH
THE NAM STILL COLDER THAN THE GFS. NEVERTHELESS...ALL MODELS
INDICATE THE VALLEYS AND BASINS WILL BE WARM ENOUGH FOR RAIN WITH
THE SNOW LEVELS GENERALLY RUNNING AROUND 8000 FEET. WE WERE
ORIGINALLY CONSIDERING ADVISORIES WITH A WELL ORGANIZED BAND OF
PRECIPITATION. HOWEVER...WITH THE MODELS NOW SHOWING MORE SPLITTING
AND LIGHTER QPF WE WILL CONTINUE THE SPECIAL WEATHER STATEMENT
INSTEAD. MEANWHILE...EAST OF THE DIVIDE IT WILL BE A COOLER DAY BUT
STILL FAIRLY CLOSE TO NORMAL. WITH THE FRONT DROPPING SOUTH AND SOME
CAPE WE HAVE INCLUDED A CHANCE OF THUNDERSTORMS FOR EVERYONE THIS
AFTERNOON AND EVENING BEFORE THE FRONT PUSHES THROUGH. WITH LOW
WET BULB ZERO TEMPERATURES WHERE COULD BE SOME SMALL HAIL WITH
ANY THUNDERSTORM.

THE COLDER AIR WILL DROP IN TONIGHT AND AS A RESULT SNOW LEVELS WILL
BEGIN TO DROP. THE MODELS HAVE COME INTO SOMEWHAT BETTER AGREEMENT
AT THIS TIME. BY 12Z WEDNESDAY 700 MILLIBAR TEMPERATURES FALL TO
AROUND MINUS 5 TO MINUS 6 NEAR CODY WHICH TRANSLATES TO AROUND 5500
TO 6000 FEET SO IT WILL BE CLOSE THERE. PRECIPITATION IN THE
MOUNTAINS SHOULD BE ALL SNOW BY THIS TIME. MEANWHILE...FURTHER EAST
THE COLDER AIR WILL BE SLOWER TO MOVE IN SO MAINLY RAIN IS EXPECTED
THROUGH THE NIGHT. WEDNESDAY LOOKS LIKE A CLOUDY AND CHILLY DAY
ACROSS MOST OF THE AREA WITH SNOW LEVELS DROPPING TO AROUND 5500 TO
6000 FEET FOR EVERYONE WITH 700 MILLIBAR TEMPERATURES FROM MINUS 5
TO MINUS 6. THIS SHOULD KEEP THE VALLEYS AND BASINS MAINLY RAIN WITH
ANY SNOW THAT DOES FALL LIKELY NOT ACCUMULATING ON ROADS DUE TO
WARMER GROUND TEMPERATURES AND THE STRONG SUN ANGLE.

THE ONE AREA FOR CONCERN STILL LOOKS TO BE WEDNESDAY NIGHT AS LEE
CYCLOGENESIS OCCURS EAST OF THE ROCKIES AND FLOW TURNS MORE TO THE
EAST AND NORTHEAST THAT COULD BRING SOME UPSLOPE. THIS STILL LOOKS
TO BE THE NIGHT SNOW LEVELS WOULD FALL TO THE VALLEY FLOORS.
HOWEVER...MOST OF BEST MOISTURE BY THIS TIME LOOKS TO BE EAST OF THE
COUNTY WARNING AREA. IT WILL BE CLOSE BUT FOR NOW WE KEPT AMOUNTS ON
THE LIGHT SIDE.

BY THURSDAY MOST OF THE STEADY PRECIPITATION SHOULD BE EAST OF THE
AREA. HOWEVER...WITH TROUGHINESS HANGING AROUND THE AREA LONG WITH
OUR OLD FRIEND UNSTABLE NORTHWESTERLY FLOW THERE WILL STILL BE
SHOWERS AROUND THE AREA BEFORE IT ENDS LATE IN THE DAY.
HOWEVER...ANOTHER SYSTEM ON ITS HEELS MAY MOVE INTO THE WEST FOR
LATE THURSDAY NIGHT.

.LONG TERM...FRIDAY THROUGH TUESDAY

UPPER RIDGE IN THE EASTERN PACIFIC IS EXPECTED TO PROGRESS ONLY
SLIGHTLY BTWN 130-125W THROUGH THIS PERIOD WHILE UPPER LOW CONTINUES
TO WOBBLE ACROSS NORTHERN ALBERTA/SASKATCHEWAN.  THIS SETUP WILL
CONTINUE TO GUIDE THE STORM TRACK FROM THE GULF OF ALASKA ACROSS THE
NORTHERN/CENTRAL ROCKIES.  SHORTWAVE NEAR 40N/160W EARLY THIS
MORNING WILL MAKE LANDFALL ALONG THE NW COAST LATE THURSDAY AND SE
ACROSS WYOMING LATE FRIDAY AFTN/FRI EVE.  THIS SYSTEM WILL BRING
INCREASING MTN SNOW AND VALLEY RAIN...SNOW LEVELS EXPECTED BTWN
7K-8KFT...FRIDAY MORNING WITH SCATTERED SHOWERS AND ISOLATED TS
SPREADING EAST OF THE DIVIDE...PRIMARILY ACROSS NORTHERN WY FRI AFTN
AND EVE WITH WHILE THE SOUTH SEES LESS SHOWERS AND MORE WIND.

MEDIUM-RANGE MODELS DIVERGE IN SOLUTIONS SUBSTANTIALLY OVER THE
WEEKEND WITH GFS EXPANDING EASTERN PACIFIC RIDGE INTO THE WESTERN
U.S. RESULTING IN A MUCH FURTHER NORTH STORM TRACK.  ECMWF AND GEM
KEEP RIDGE OFF THE WEST COAST...WITH GULF OF AK UPPER LOW SLIDING
DOWN THE FRONT SIDE OF THE RIDGE INTO THE GREAT BASIN ON SUNDAY.
THIS LATTER SOLUTION HAS BEEN THE MOST CONSISTENT WITH GFS LIKELY
TOO PROGRESSIVE WITH LONGWAVE PATTERN.

GOING MAINLY WITH ECMWF...ON SATURDAY FLAT RIDGING MAKES A BRIEF
APPEARANCE OVER THE NORTHERN ROCKIES BTWN EXITING SHORTWAVE OVER THE
NORTHERN PLAINS AND UPPER LOW MAKING LANDFALL ALONG THE NW COAST.
WINDY CONDITIONS WILL CONTINUE ACROSS SOUTHERN WYOMING WITH SCT
VALLEY AND NMRS MTN SHOWERS ACROSS MAINLY THE NORTHERN THIRD OF THE
AREA.

UPPER LOW WILL DIG ACROSS THE GREAT BASIN/CENTRAL ROCKIES SUNDAY AND
MONDAY WITH UPSLOPE NE FLOW DEVELOPING EAST OF THE DIVIDE ON SUNDAY
ALONG WITH HIGHER CHANCES OF RAIN AND SNOW.  FORECAST KEEPS HIGH
TEMPS A FEW DEGREES WARMER THAN ECMWF GUIDANCE RIGHT NOW WITH
LOW/MEDIUM CONFIDENCE IN TIMING AND VERTICAL THERMAL PROFILE...SNOW
LEVELS NEAR 7KFT.  UPPER LOW IS FORECAST TO PUSH OUT INTO THE
CENTRAL HIGH PLAINS ON MONDAY SHIFTING THE BEST CHANCES OF RAIN AND
SNOW ACROSS EAST CENTRAL WYOMING.  A COOL AND UNSETTLED NW FLOW IS
EXPECTED TO FOLLOW ON TUESDAY WITH ISOLD/SCT RAIN AND SNOW SHOWERS
AND BELOW NORMAL TEMPS.
