BECOMING NORTH AND GUSTING TO 45 MPH FOR A FEW HOURS AFTER COLD
FRONTAL PASSAGE. VFR...EXCEPT FOR LOCALIZED AREAS OF MVFR FOR A
FEW HOURS AFTER COLD FRONTAL PASSAGE.  RUBIN

&&

.PREV DISCUSSION... /ISSUED 1057 AM MDT WED OCT 3 2012/

UPDATE...
COLD FRONT MOVING SOUTH RATHER QUICKLY ACROSS CENTRAL WYOMING NOW
AND EXPECT IT TO PASS ACROSS THE REST OF THE CWA BY LATE THIS
AFTERNOON. TEMPERATURES WARMER OVER THE SOUTHERN PORTION OF THE
CWA AND HAVE ADJUSTED UPWARD SOME. OTHERWISE REST OF FCST IN
DECENT SHAPE.

FIRE WEATHER...HAVE ISSUED A RED FLAG WARNING FOR THE SOUTHERN
PANHANDLE UNTIL 4 PM AS CRITICAL CONDITIONS OCCURRING THERE NOW
AND SHOULD LAST INTO MID AFTERNOON BEFORE MUCH COOLER AIR ARRIVES
BEHIND THE COLD FRONT.

PREV DISCUSSION... /ISSUED 443 AM MDT WED OCT 3 2012/

SHORT TERM...TODAY THROUGH FRIDAY...MAJOR CHANGE IN THE WEATHER
PATTERN THIS WEEK AS AUTUMNS FIRST MAJOR COLD FRONT APPROACHES
THE AREA. CURRENT IR SATELLITE LOOP SHOWS THE COLD FRONT JUST
STARTING TO ENTER NORTHERN WYOMING EARLY THIS MORNING WITH GUSTY
NORTH WINDS OBSERVED NEAR THE MONTANA BORDER. MODELS ARE NOW
STRUGGLING WITH THE TIMING OF THE FRONT AND NOW SHOW IT MOVING
THROUGH CONVERSE AND NIOBRARA COUNTIES AROUND NOON AND THE I80
CORRIDOR LATE IN THE AFTERNOON. MODELS TEND TO UNDERESTIMATE HOW
FAST THESE WELL DEFINED FRONTS MOVE ACROSS THE PLAINS...SO STILL
BELIEVE THE FRONT WILL MOVE ACROSS THE AREA A FEW HOURS EARLIER
THAN EXPECTED BASED ON PAST EVENTS. MUCH COLDER AIR WILL THEN PUSH
INTO THE REGION LATE THIS AFTERNOON AND TONIGHT...WITH LOWS IN THE
20S EXPECTED. ISSUED A FREEZE WATCH FOR PORTIONS OF THE AREA
INCLUDING THE SOUTHERN PANHANDLE OF NEBRASKA AND MOST OF THE HIGH
PLAINS OF WYOMING. KEPT ALBANY COUNTY...NORTHERN NEBRASKA
PANHANDLE...AND THE MOUNTAINS OUT OF THE WATCH SINCE THOSE
LOCATIONS HAVE ALREADY OBSERVED TEMPERATURES AT OR BELOW FREEZING
THIS FALL. IN ADDITION...ISSUED A WIND ADVISORY FOR WESTERN
NEBRASKA WITH NORTHERLY WIND GUSTS UP TO 50 MPH POSSIBLE AS THE
FRONT QUICKLY MOVES SOUTH. MODELS HAVE CONTINUED TO TREND DRIER
WITH MOST MODEL RUNS INDICATING HARDLY ANY PRECIP AT ALL OUTSIDE
OF A FEW SPRINKLES OR FLURRIES TONIGHT. CONTINUED TO LOWER POP
BELOW 15 PERCENT SOUTH OF THE PLATTE RIVER VALLEY.

UPPER LEVEL TROUGH WILL QUICKLY PUSH EASTWARD AND INTENSIFY NEAR
THE GREAT LAKES ON THURSDAY. A CHILLY DAY IS EXPECTED ACROSS THE
WHOLE FORECAST AREA WITH HIGHS IN THE 40S AND 50S. MODELS SHOW THE
COLD FRONT BECOMING A STATIONARY FRONT ALONG THE MOUNTAINS WITH
EASTERLY UPSLOPE FLOW. MODEL SOUNDINGS SHOW A LAYER OF LOW STRATUS
CLOUDS DURING THE DAY RESULTING IN MOSTLY CLOUDY SKIES...ALTHOUGH
NO PRECIPITATION IS EXPECTED. KEPT POP BELOW 5 PERCENT ON
THURSDAY.

FOR FRIDAY...SECONDARY UPPER LEVEL TROUGH WILL DIG SOUTHWARD INTO
WYOMING STARTING FRIDAY MORNING. WITH EASTERLY UPSLOPE FLOW
DEVELOPING ACROSS THE AREA AND WARM AIR OVERRUNNING ALOFT...BELIEVE
THIS WILL RESULT IN A BETTER CHANCE TO SEE THE FIRST SNOW FLAKES
THIS AUTUMN. INCREASED POP BETWEEN 40 TO 55 PERCENT EAST OF THE
LARAMIE RANGE...WITH LESSER VALUES WEST OF THE LARAMIE RANGE.
FRIDAY WILL LIKELY BE EVEN COLDER WITH A REINFORCING SHOT OF COLD
AIR MOVING ACROSS THE REGION. HIGH TEMPERATURES MAY STRUGGLE TO
REACH 40 DEGREES...WITH THE WARMEST TEMPERATURES ACTUALLY WELL
WEST OF THE LARAMIE RANGE WHERE THE FRONT IS EXPECTED TO STALL.
ANY SNOW ACCUMULATIONS APPEAR TO BE LESS THAN AN INCH WITH MAYBE 1
TO 3 INCHES ACROSS THE LARAMIE RANGE.

LONG TERM...FRIDAY NIGHT THROUGH TUESDAY...
THERE IS GOOD AGREEMENT WITH THE 00Z MEDIUM RANGE MODEL GUIDANCE
THROUGHOUT THE EXTENDED FORECAST PERIOD. THE REX BLOCK PATTERN OVER
THE EASTERN PACIFIC WILL TRANSITION TO A MEAN RIDGE OFFSHORE THE
PACIFIC COAST AS AN UPPER LOW MOVES SOUTHEAST THROUGH CALIFORNIA.
MEANWHILE...A MEAN UPPER TROUGH WILL REMAIN ANCHORED FROM THE
ROCKIES TO THE EASTERN CONUS. THERE WILL BE PERIODIC UPPER LEVEL
SHORTWAVES DIVING SOUTHEAST FROM WEST CENTRAL CANADA TO REINFORCE
THE TROUGH. 500MB HEIGHT AND 1000MB TEMPERATURE ANOMALIES WILL
RANGE FROM 2 TO 4 DEVIATIONS BELOW NORMAL FROM THE NORTHERN AND
CENTRAL ROCKIES EASTWARD THROUGH THE PLAINS THIS WEEKEND. THESE
ANOMALOUSLY LOW VALUES WILL EQUATE TO WELL BELOW NORMAL TEMPERATURES
WITH HIGHS IN THE 30S AND 40S SATURDAY AND 40S AND 50S SUNDAY.
LOW TEMPERATURES WILL BE IN THE TEENS AND 20S. 700MB TEMPERATURES
WILL RANGE FROM -6 TO -12C...SO THE AIRMASS WILL BE COLD ENOUGH TO
SUPPORT SNOW FRIDAY NIGHT AND SATURDAY MORNING AS A PASSING UPPER
LEVEL SHORTWAVE AND UPSLOPE LOW LEVEL FLOW COMBINE WITH MOISTURE
ALOFT. AT THIS TIME...SNOW ACCUMULATIONS WILL BE LIGHT...GENERALLY
ON THE ORDER OF ONE TO TWO INCHES. LIGHT RAIN AND SNOW WILL TAPER
OFF SATURDAY AFTERNOON OVER THE SNOWY AND LARAMIE RANGES AS WELL
AS FAR SOUTHEAST WYOMING AND SOUTHERN NEBRASKA PANHANDLE.

THE FLOW ALOFT BACKS FROM NORTH TO NORTHWEST WITH THE INFLUENCE
OF THE UPPER RIDGE WEST OF THE CONTINENTAL DIVIDE BRINGING DRIER
CONDITIONS AND MODERATING TEMPERATURES FOR MONDAY. HIGH TEMPERATURES
WILL BE NEAR SEASONAL NORMALS MONDAY WITH AFTERNOON READINGS IN
THE 60S FOR LOWER ELEVATIONS. 40S AND 50S WILL BE COMMON OVER THE
HIGH COUNTRY. TUESDAY WILL SEE A CHANGE TO COOLER TEMPERATURES AS
ANOTHER CLIPPER COLD FRONT SWEEPS SOUTHEAST THROUGH THE REGION.
SOME LIGHT UPSLOPE RAIN WILL BE POSSIBLE OVER THE NORTHERN LARAMIE
RANGE AND SOUTHERN MOUNTAINS MONDAY AFTERNOON.

AVIATION...12Z TAF ISSUANCE...
VFR CONDITIONS WILL PREVAIL WITH CLOUDS INCREASING AND LOWERING
FOLLOWING A COLD FRONTAL PASSAGE FROM LATE MORNING THROUGH LATE
AFTERNOON. A TIGHT SURFACE PRESSURE GRADIENT WILL GENERATE GUSTY
WESTERLY WINDS PRIOR TO FRONTAL PASSAGE WITH GUSTS OF 30 TO 40 KT.
THESE WINDS WILL GENERATE MODERATE TURBULENCE DOWNWIND OF THE
MOUNTAINS. SURFACE WINDS SHIFT ABRUPTLY TO NORTHERLY WITH GUSTS
TO 35 KT AFTER FRONTAL PASSAGE. LOW LEVEL NORTHEAST UPSLOPE FLOW
WILL PRODUCE SOME LIGHT RAIN AND SNOW SHOWERS DURING THE LATE
AFTERNOON AND EVENING OVER THE MOUNTAINS AND EAST OF A LINE FROM
DOUGLAS TO KIMBALL. CEILINGS MAY LOWER TO MVFR LATER THIS EVENING
AND OVERNIGHT ACROSS THE EASTERN WYOMING PLAINS AND WESTERN
PANHANDLE.
