AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
327 PM MDT SAT MAR 24 2012

.SHORT TERM...TODAY THROUGH TUESDAY

A WEAK COLD FRONT MOVED SOUTH OVERNIGHT AND WASHED OUT OVER
CENTRAL WYOMING TODAY...LEADING TO SLIGHTLY COOLER TEMPERATURES
AND HIGHER RELATIVE HUMIDITIES OVER MUCH OF THE NORTHERN AND
CENTRAL PORTIONS OF THE STATE. SOUTHERN PORTIONS WILL REMAIN DRY
AND WINDY INTO THE EARLY EVENING AS HIGH PRESSURE REMAINS IN
CONTROL.

THE UPPER LEVEL RIDGE WILL BEGIN TO BREAK DOWN ON SUNDAY...LEADING
TO WINDIER CONDITIONS EAST OF THE DIVIDE AND THE POSSIBILITY OF
SHOWERS AND EVEN A FEW THUNDERSTORMS WEST OF THE DIVIDE ON SUNDAY
AFTERNOON. TEMPERATURES WILL BE ON THE RISE EAST OF THE DIVIDE
ALONG WITH THE WIND SPEEDS. RELATIVE HUMIDITIES WILL BE DIPPING
INTO THE TEENS ACROSS MUCH OF WYOMING...ALL FIRE WEATHER WATCHES
APPEAR TO BE ON TRACK FOR SUNDAY AFTERNOON.

AN UPPER LEVEL TROUGH SWINGS THROUGH ON MONDAY...AT THE SAME
TIME...THE SURFACE LOW WILL DEEPEN RAPIDLY ALONG THE MONTANA AND
WYOMING BORDER. ITS ASSOCIATED COLD FRONT WILL RAKE ACROSS THE
STATE FROM WEST TO EAST RAPIDLY ON MONDAY MORNING...RAIN IS
EXPECTED ACROSS THE STATE A BIT EARLIER THAN PREVIOUSLY
ANTICIPATED...HAVE CANCELLED THE FIRE WEATHER WATCH ACROSS THE
SOUTH AS A RESULT. IN ADDITION...RELATIVE HUMIDITIES ACROSS
CENTRAL PORTIONS OF THE STATE ARE NOT EXPECTED TO DROP ENOUGH
AHEAD OF THE FRONTAL PASSAGE ON MONDAY...SO HAVE DROPPED THE FIRE
WEATHER WATCH THERE AS WELL. INSTEAD...THE WINDS ASSOCIATED WITH
THIS SYSTEM APPEAR TO BE VERY STRONG...WITH SEVERAL 60+ KNOT WIND
BARBS APPEARING AT H7 ACROSS MUCH OF THE AREA IN ADDITION TO THE
RAPIDLY DEEPENING SURFACE LOW...SO HAVE REPLACED THE FIRE WEATHER
WATCHES WITH STRONG WIND WATCHES ON MONDAY...WITH THE EXCEPTION OF
NORTHEASTERN PORTIONS OF THE STATE...THE FRONT MAY TAKE A LITTLE
LONGER TO GET THERE SO RHS COULD CONCEIVABLY DROP INTO THE MID
TEENS BEFORE THE COOL AND MOIST AIR ARRIVES. IN ADDITION...SOME
MARGINAL INSTABILITY WILL ACCOMPANY THE TROUGH...SO HAVE INCLUDED
MENTION OF THUNDERSTORMS ON MONDAY AS WELL.

WEAK HIGH PRESSURE WILL BUILD BACK IN ON TUESDAY...WITH RELATIVELY
COOL AIR REMAINING BEHIND MONDAY'S COLD FRONT.

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY

A RIDGE AXIS WILL TRAVERSE ACROSS WYOMING TUESDAY NIGHT. A WEST
SOUTHWEST DIFLUENT UPSLOPE FLOW WILL GET UNDERWAY BEHIND THE RIDGE
AXIS WEDNESDAY RESULTING IN AN INCREASING CHANCE OF RAIN AND SNOW
SHOWERS IN WESTERN WYOMING. THESE SHOWERS WILL PERSIST THROUGH
THURSDAY AS THE SECOND MAIN UPSTREAM TROUGH...NOW OFF THE
ALEUTIANS...EJECTS A SHORTWAVE WITH AN ASSOCIATED VORT MAX THAT WILL
SCOOT EAST ACROSS SOUTHERN CANADA ALONG WITH A TRAILING TROUGH
SHORTWAVE TROUGH ACROSS THE ROCKIES THURSDAY. THEN THE MAIN TROUGH
WILL MAKE LANDFALL FRIDAY. A LEAD SHORTWAVE FROM THIS MAIN TROUGH
WILL TRACK EAST ACROSS THE AREA FRIDAY WITH INCREASING PRECIP IN THE
WEST. THEN THE GFS PLOWS THE MAIN TROUGH AXIS THROUGH WYOMING
SATURDAY. THE ECMWF KEEPS THE TROUGH MORE FULLY LATITUDINAL JUST OFF
THE PACIFIC COAST THROUGH SATURDAY. EITHER SCENARIO WILL LIKELY GIVE
THE FAR WEST A HIGHER CHANCE OF PRECIP SATURDAY WITH THE GFS VERSION
GIVING THE BIG HORN MOUNTAINS SOME POPS AS WELL. GAVE THE BIG HORN
MOUNTAINS LESSER POPS FOR SATURDAY. IN ADDITION...INCREASING
SOUTHWEST WINDS ALONG THE SOUTHERN WIND CORRIDOR AHEAD OF THE
APPROACHING ASSOCIATED COLD FRONT ARE ALSO EXPECTED. EXPECT MILD
TEMPS THROUGH THE EXTENDED WITH MANY HIGHS IN THE 70S EXPECTED
SATURDAY EAST OF THE DIVIDE. H7 TEMPS ARE PROGGED TO BE 5C OVER
THE SOUTHEAST CWA BY 00Z SUNDAY.

.FIRE WEATHER...

A WEAK COLD FRONT WASHED OUT OVER CENTRAL WYOMING TODAY...LEADING
TO INCREASED DAYTIME HUMIDITY ACROSS THE NORTHERN TWO THIRDS OF
THE FORECAST AREA. MARGINALLY DRY AND WINDY CONDITIONS ACROSS
SWEETWATER COUNTY WILL CONTINUE INTO THE EARLY EVENING HOURS.

HAZARDOUS FIRE BEHAVIOR MAY RETURN TO THE AREA ON SUNDAY
...ESPECIALLY IMPACTING SWEETWATER...NATRONA...FREMONT... AND
JOHNSON COUNTIES. A FIRE WEATHER WATCH HAS BEEN ISSUED FOR THESE
AREAS...WHERE CONDITIONS MAY BE HAZARDOUS DURING THE AFTERNOON AND
EVENING HOURS OF SUNDAY...AND MONDAY ACROSS NORTHEASTERN PORTIONS.
THE FIRE WEATHER WATCHES FOR MONDAY ACROSS SOUTHERN AND CENTRAL
ZONES HAVE BEEN DROPPED BECAUSE RHS ARE EXPECTED TO RISE AHEAD OF
AND ALONG WITH A COLD FRONTAL PASSAGE ON MONDAY MORNING.
HOWEVER...MONDAY WILL STILL BE A DANGEROUS DAY FOR FIRE DUE TO THE
WIDESPREAD STRONG WINDS. A HIGH WIND WATCH HAS REPLACED THE FIRE
WEATHER WATCHES FOR MONDAY. DEPENDING UPON THE TIMING OF THE COLD
FRONT...RHS COULD STILL DROP TO NEAR 20 PERCENT..WHEN COMBINED
WITH WIDESPREAD STRONG WINDS COULD STILL LEAD TO ELEVATED FIRE
BEHAVIOR.
