1014 AM MST SAT JAN 21 2012
.AVIATION...18Z TAFS
MAINLY VFR CONDITIONS IN GUSTY WEST TO SOUTHWEST WINDS TODAY.
RAWLINS MAY SEE A PERIOD THOUGH THIS AFTERNOON WHERE FLIGHT
CONDITIONS COULD DETERIORATE TO IFR IN SNOW AND BLOWING SNOW...
MAINLY AFTER 23Z. BY THIS EVENING...A COLD FRONT LOOKS TO MOVE
THROUGH THE AREA WITH WINDS SHIFTING MORE NORTHWESTERLY. EXPECTING
MOUNTAIN OBSCURATIONS OVER CARBON COUNTY NEAR RAWLINS PERSISTING
INTO SUNDAY MORNING. STRONG NORTHWEST WINDS ONCE AGAIN LIKELY
ACROSS THE SOUTHERN LARAMIE RANGE INTO THE SOUTHERN NEBRASKA
PANHANDLE SUNDAY.
&&
.PREV DISCUSSION... /ISSUED 936 AM MST SAT JAN 21 2012/
UPDATE...
ISSUED A HIGH WIND WATCH FOR LARAMIE COUNTY AND THE SOUTHERN
NEBRASKA PANHANDLE FROM SUNDAY MORNING THROUGH SUNDAY AFTERNOON.
COLD AIR ADVECTION/PRESSURE RISES BEHIND THE FROPA SUNDAY MORNING
ALONG WITH GOOD LLVL LAPSE RATES AND 700MB WINDS AROUND 55 KTS
WILL COMBINE TO PRODUCE STRONG AND GUSTY WINDS. STILL EXPECT
SNOWFALL TO PICK UP THIS EVENING ACROSS THE SIERRA MADRE AND SNOWY
RANGES AS LIFT AND MOISTURE ASSOCIATED WITH THE TROUGH INCREASES.
&&
PREV DISCUSSION.../ISSUED 334 AM MST SAT JAN 21 2012/
SHORT TERM...TODAY THROUGH MONDAY
THE PREDAWN WATER VAPOR IMAGERY ANIMATION DEPICTED A VERY ACTIVE
UPPER LEVEL WEATHER PATTERN AS A INTENSE JET STREAM FROM THE EASTERN
PACIFIC PLOWS INTO THE WESTERN CONUS. A VERY MOIST FLOW OFF THE
PACIFIC CONTINUED TO PRODUCE WIDESPREAD MODERATE TO HEAVY PRECIPITATION
FROM THE WEST COAST INTO THE GREAT BASIN. FURTHER EAST OVER OUR
FORECAST AREA... RIDGING ALOFT MAINTAINED DRY CONDITIONS WITH
INCREASING WEST TO SOUTHWEST WINDS IN THE LOW LEVELS. THE MEDICINE
BOW WIND PROFILER INDICATED A GRADUAL UPTICK IN THE LOWEST GATE
WINDS FROM 40 TO 50 KT. THE WIND CORRIDOR BETWEEN LARAMIE AND
RAWLINS REPORTED WIND GUSTS UP TO 55 MPH AT ARLINGTON...WITH 40 TO
50 MPH FROM THE NORTHERN LARAMIE RANGE WESTWARD. IN A RECENT
UPDATE...INCLUDED THE NORTHERN CARBON COUNTY MOUNTAINS IN THE HIGH
WIND WARNING FOR GAP WINDS THERE. THE STUBBORN BOUNDARY WITH
SHALLOW COLD AIR MASS TO ITS EAST ACROSS THE WESTERN NEBRASKA
PANHANDLE HAS FINALLY BEGUN TO SLOWLY SHIFT EAST AS SOUTHWESTERLY
LOW LEVEL FLOW INCREASES. TEMPERATURES HAVE BEEN RISING SEVERAL
DEGREES SINCE MIDNIGHT IN THIS AREA.
THE MAIN FORECAST CHALLENGES DURING THE SHORT TERM WILL BE HIGH
WINDS TODAY AND AGAIN SUNDAY FOR PARTS OF SOUTHERN WYOMING AS WELL
AS THE POTENTIAL FOR SIGNIFICANT SNOWFALL ACROSS THE MOUNTAINS OF
CARBON COUNTY TODAY THROUGH SUNDAY.
THERE/S GOOD CONTINUITY BETWEEN THE 00Z AND PREVIOUS RUNS OF THE
SHORT RANGE MODEL SOLUTIONS. UPPER RIDGE AXIS WILL CONTINUE TO
MARCH EAST INTO THE PLAINS TODAY...WITH THE BELT OF 110-120 KT
WINDS CONFINED TO NORTHERN PLAINS. STILL LOW LEVEL (850/700 MB)
PRESSURE/HEIGHT GRADIENTS ARE RATHER LARGE...SUPPORTIVE OF A HIGH
WIND EVENT FOR PORTIONS OF SOUTHERN WYOMING TODAY...INCLUDING
THE CENTRAL/SOUTHERN LARAMIE RANGE/FOOTHILLS...NORTH SNOWY RANGE
AND NORTHERN CARBON COUNTY MOUNTAINS. WEST TO SOUTHWEST WINDS OF
35 TO 45 MPH WITH GUSTS OF 60 TO 70 MPH ARE EXPECTED IN THESE
AREAS AND HIGH WIND WARNINGS ARE NOW IN EFFECT UNTIL 5 PM THIS
AFTERNOON. THE WINDS SHOULD GRADUALLY DECREASE TONIGHT AS A PACIFIC
COLD FRONT MOVES ACROSS WYOMING...BUT INCREASE ONCE AGAIN ON
SUNDAY FROM THE NORTHWEST ON THE SUBSIDENT SIDE OF THE UPPER LEVEL
JET. IT LOOKS LIKE A MARGINAL BORA WIND EVENT FOR SOUTHEAST
WYOMING SUNDAY...WITH WINDY CONDITIONS FOR MUCH OF THE WESTERN
NEBRASKA PANHANDLE. ADDITIONAL WIND HEADLINES MAY BE REQUIRED
LATER TODAY.
A RATHER POTENT 250 MB JET STREAK WILL MOVE QUICKLY EAST ACROSS
UTAH AND COLORADO THIS AFTERNOON AND TONIGHT...WITH SOUTHERN
WYOMING AND NORTHERN COLORADO ON ITS LEFT EXIT REGION. THIS
TYPICALLY IS WHERE UPWARD VERTICAL MOTION/LIFT RESIDES...WHICH
ENHANCES PRECIPITATION. THIS WILL BE THE CASE AS RAIN AND SNOW
INITIALLY DEVELOPS THIS MORNING OVER CARBON COUNTY. COLDER AIR
ALOFT THIS EVENING WILL CAUSE THE SNOW LEVEL TO DROP FROM 6000
FT TO 4000 FT. SNOW WILL BECOME MODERATE TO HEAVY AT TIMES...
ESPECIALLY OVER THE MOUNTAINS AND HIGHER VALLEYS TONIGHT AND
PERSIST THROUGH SUNDAY MORNING. TOTAL STORM SNOWFALL AMOUNTS
HAVE NOT CHANGED SINCE YESTERDAY WITH 8 TO 16 INCHES FOR THE
SNOWY AND SIERRA MADRE RANGES. HIGHER AMOUNTS WILL BE POSSIBLE
ALONG WEST FACING SLOPES. FOR THE SURROUNDING VALLEYS...3 TO 6
INCHES ARE EXPECTED. THE COMBINATION OF VERY STRONG AND GUSTY
WINDS WILL CREATE EXTREMELY HAZARDOUS TRAVEL CONDITIONS WITH
CONSIDERABLE BLOWING/DRIFTING SNOW. WINTER STORM WARNINGS AND
WEATHER ADVISORIES REMAIN IN EFFECT FOR TODAY THROUGH SUNDAY
MORNING. WHILE SOME OF THE PACIFIC MOISTURE WILL MAKE IT EAST
OF THE LARAMIE RANGE THIS AFTERNOON AND TONIGHT...ONLY LIGHT
AMOUNTS OF RAIN AND SNOW ARE FORECAST FOR THE PLAINS. THE
DOWNSLOPING FLOW WILL KEEP TEMPERATURES QUITE MILD ON THE
PLAINS WITH 50S TODAY. IT WILL TURN COLDER FROM WEST TO EAST
TONIGHT AND SUNDAY WITH THE PASSAGE OF THE COLD FRONT. HIGH
TEMPERATURES SUNDAY WILL BE 10 TO 15 DEGREES COLDER...WITH
THE GUSTY NORTHWEST WINDS MAKING IT FEEL EVEN COLDER. LIGHT
SNOW WILL LINGER FOR THE SNOWY AND SIERRA MADRE RANGES THROUGH
SUNDAY NIGHT...WHILE THE REMAINDER OF THE FORECAST AREA DRIES
OUT. THE NEXT UPPER LEVEL WEATHER SYSTEM WILL MOVE TOWARD THE
FOUR CORNERS REGION MONDAY AFTERNOON...WITH SNOW SPREADING
INTO WESTERN CARBON COUNTY. WILL SEE A 5 TO 10 DEGREE TEMPERATURE
MODERATION MONDAY AS DOWNSLOPING FLOW INCREASES IN ADVANCE
OF THE NEXT PACIFIC COLD FRONT ENTERING THE COWBOY STATE.
WEST TO SOUTHWEST WINDS WILL INCREASE FOR THE WIND CORRIDORS
OF SOUTHEAST WYOMING DURING THE AFTERNOON AS WELL.
LONG TERM...MONDAY NIGHT THROUGH FRIDAY...
21/00Z GFS AND ECMWF SIMILAR AT 500 MB THUS MODERATE TO HIGH
CONFIDENCE IN THEIR RESPECTIVE MODEL SOLUTIONS.
MONDAY NIGHT...NEXT SHORTWAVE TROUGH ALOFT BEGINS TO AFFECT OUR
COUNTIES PRODUCING INCREASING CHANCES FOR SNOW AS THE NIGHT
PROGRESSES AND THE ATMOSPHERE BECOMES INCREASINGLY MOIST.
TUESDAY...SHORTWAVE TROUGH ALOFT MOVES TO OUR EAST OVER THE CENTRAL
PLAINS STATES WITH A DRYING PATTERN ACROSS OUR COUNTIES. COLDER IN
THE WAKE OF A COLD FRONT.
WEDNESDAY...WARMING TREND BEGINS WITH RISING HEIGHTS ALOFT AND
1000-500 MB THICKNESSES CLIMBING TO NEAR 5520 METERS. WILL BE WINDY
BASED ON PROGGED SURFACE THROUGH 700 MB GRADIENTS.
THURSDAY...SLOW WARMING TREND CONTINUES WITH FAST WEST FLOW ALOFT
AND 1000-500 MB THICKNESSES NEAR 5520 METERS. STILL WINDY WITH
DECENT SURFACE THROUGH 700 MB GRADIENTS.
FRIDAY...NEXT PROGRESSIVE AND QUICK MOVING LOW AMPLITUDE SHORTWAVE
TROUGH ALOFT PROGGED TO MOVE ACROSS OUR COUNTIES...THOUGH TIMING
THIS FAR OUT IS IFFY AT BEST. GFS LIKELY OVERDONE ON CLOUDS AND QPF
THOUGH WOULD STILL EXPECT SCATTERED OROGRAPHIC SNOW SHOWERS ACROSS
THE NORTHERN LARAMIE ...SNOWY AND SIERRA MADRE RANGES.
&&
FIRE WEATHER...
NO FIRE WEATHER CONCERNS ARE EXPECTED THIS WEEKEND. STRONG AND
GUSTY WEST TO SOUTHWEST WINDS WILL OCCUR OVER PORTIONS OF SOUTH
CENTRAL AND SOUTHEAST WYOMING THROUGH LATE THIS AFTERNOON THEN
SLOWLY DIMINISH TONIGHT. WINDS WILL SHIFT TO THE WEST AND NORTHWEST
AND BECOME STRONG AND GUSTY SUNDAY IN THE WAKE OF A COLD FRONTAL
PASSAGE. A POTENT UPPER LEVEL STORM SYSTEM WILL PRODUCE WIDESPREAD
RAIN AND SNOW FOR LOWER ELEVATIONS AND HIGH ELEVATION SNOW WEST
OF THE LARAMIE RANGE TODAY THROUGH SUNDAY. THE SNOW WILL BE HEAVY
AT TIMES WITH STRONG WINDS GENERATING CONSIDERABLE BLOWING AND
DRIFTING SNOW. AREAS EAST OF THE LARAMIE RANGE WILL SEE LIMITED
MOISTURE WITH SMALL CHANCES FOR LIGHT RAIN AND SNOW. MINIMUM
AFTERNOON RELATIVE HUMIDITIES WILL RANGE FROM 25 TO 40 PERCENT
ACROSS THE SOUTHEAST WYOMING PLAINS AND NEBRASKA PANHANDLE TODAY
AND SUNDAY.
