AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
1038 AM MST WED FEB 22 2012
.UPDATE...FORECAST FOR TODAYS HIGH WIND EVENT SO FAR ON TRACK...WITH
WINDS STEADILY ON THE INCREASE ACROSS THE FORECAST AREA THIS
MORNING. STRONGEST WINDS STILL EXPECTED TO OCCUR THIS AFTERNOON
ACROSS THE FORECAST AREA...WITH HIGH WINDS LINGERING ALONG THE
INTERSTATE 25 CORRIDOR AND WESTWARD TO ARLINGTON THROUGH THE
OVERNIGHT PERIOD. FRONT LOOKS TO MOVE THROUGH SOUTHERN PORTIONS OF
THE FORECAST AREA BETWEEN MIDNIGHT AND 3AM SO SHOULD CONTINUE TO
SEE THE GRADIENT REMAIN VERY STRONG IN THIS AREA AHEAD OF THE
FRONT. EXTENDED THE WARNING TO 2 AM FOR THE ZONES THAT INCLUDE
ARLINGTON...VEDAUWOO...AND INTESTATE 25 FOR
BORDEAUX...WHITAKER...AND WYO HILL AS A RESULT.
ADDITIONALLY...RADAR RETURNS ARE MORE WIDESPREAD ACROSS THE
EASTERN PLAINS WITH SOME OBSERVATIONS SITES REPORTING RAIN AND/OR
SNOW UNDER THESE RETURNS. BUMPED UP POPS FOR THE REMAINDER OF THE
DAY TO ACCOUNT FOR THIS LIGHT PRECIP ALTHOUGH AMOUNTS WILL REMAIN
VERY LIGHT. RJM
&&
.PREV DISCUSSION... /ISSUED 436 AM MST WED FEB 22 2012/
AVIATION...12Z TAFS
WINDS WILL BE THE MAIN PROBLEM INITIALLY TODAY AT ALL SOUTHEAST
WYOMING AND NEBRASKA PANHANDLE AIRPORTS. WIND GUSTS IN EXCESS OF
50KT LOOK TO BECOME WIDESPREAD AFTER SUNRISE...CONTINUING THROUGH
THE AFTERNOON. A COLD FRONT WILL APPROACH FROM THE NORTH THIS
EVENING. EXPECTING SNOW TO BEGIN AFTER 00Z AND THIS WILL REDUCE
FLIGHT CONDITIONS DOWN TO IFR/LIFR BY 05Z OR SO. EXPECT THESE LOW
CONDITIONS TO CONTINUE THROUGH MID MORNING THURSDAY.
CLAYCOMB
PREV DISCUSSION... /ISSUED 337 AM MST WED FEB 22 2012/
SHORT TERM...TODAY THROUGH THURSDAY NIGHT
STRONG WIND EVENT CONTINUES TO LOOK ON TRACK THROUGH THIS EVENING.
THE MEDICINE BOW PROFILER AT 08Z SHOWS WESTERLY WINDS AT 55 KTS IN
THE LOWEST GATE WITH 65 KTS AT 700MB. THE WIND PRONE AREAS OF
ARLINGTON...BORDEAUX...AND VEDAUWOO HAVE BEEN HITTING LOW END HIGH
WIND CRITERIA OVERNIGHT. STILL EXPECT WINDS TO INTENSIFY AND
SPREAD ONTO THE LOWER ELEVATIONS EAST OF THE LARAMIE RANGE BY LATE
MORNING DUE TO THE FOLLOWING FACTORS. STRONG SHORTWAVE IN THE
MIDLEVEL NORTHWESTERLY FLOW CURRENTLY MOVING ACROSS WASHINGTON IS
FCSTED TO MOVE SOUTHEASTWARD DURING THE DAY. SFC PRESSURE FALLS
OCCUR DURING THE DAY OVER THE NORTHERN PLAINS WITH A 989MB SFC LOW
DEVELOPING OVER EASTERN MT AT 00Z. IN ADDITION TO A TIGHTENING
SFC PRESSURE GRADIENT...LLVL HEIGHT DIFFERENCES AND WINDS INCREASE
DURING THE MORNING. THE GFS HAS BEEN CONSISTENT IN SHOWING 700MB
WINDS INCREASING TO AROUND 75 KTS BY 18Z. THE WRKHGT PRODUCT
INDICATES THE 700MB CAG-CPR GRADIENT WILL STRENGTHEN FROM 82M
CURRENTLY TO AROUND 100M BY 18Z. IMPROVING LLVL LAPSE RATES
DURING THE LATE MORNING AND AFTERNOON WILL SUPPORT MIXING THE VERY
STRONG LLVL WINDS TO THE SURFACE...WITH GUSTS TO 80 MPH POSSIBLE
OVER SOUTHEAST WY. A COLD FRONT ASSOCIATED WITH THE SHORTWAVE WILL
PASS OVER THE CWA THIS EVENING AND OVERNIGHT. BREEZY TO WINDY
CONDITIONS WILL REMAIN OVER THE CWA THROUGH THURS NIGHT...HOWEVER
WINDSPEEDS WILL FALL BELOW HIGH WIND CRITERIA BEHIND THE COLD
FRONT AS LLVL HEIGHT GRADIENTS DECREASE.
THE VERY MOIST NORTHWESTERLY FLOW COMING FROM THE EASTERN PACIFIC
HAS PRODUCED SOME IMPRESSIVE OROGRAPHIC SNOWFALL TOTALS ACROSS
THE SIERRA MADRE AND SNOWY RANGES. SINCE MIDDAY TUESDAY SNOWFALL
ACCUMULATIONS HAVE BEEN GENERALLY 8 TO 12 INCHES ACROSS THESE
RANGES. HOWEVER...THE SNOTEL AT LITTLE SNAKE RIVER AND WHISKEY
PARK SHOWS 24 AND 21 INCHES RESPECTIVELY. WHILE BOTH THE NAM AND GFS
HAVE UNDER PREDICTED QPF AMOUNTS OVER THE PAST DAY...THE NAM HAS DONE
BETTER FCSTING THE HIGHER AMOUNTS ASSOCIATED WITH THE STRONG
OROGRAPHICS. INCREASED THE SNOWFALL TOTALS THROUGH THURSDAY
MORNING...WITH AN ADDITIONAL 6 TO 9 INCHES EXPECTED AND LOCALLY
HIGHER AMOUNTS ON WEST/NORTHWEST FACING SLOPES. AN INCREASE IN
SNOWFALL RATES WILL OCCUR AS THE MIDLEVEL FRONT/LIFT MOVE OVER THE
MTNS BETWEEN 00Z-12Z THURS. WITH REGARD TO PRECIP CHANCES ACROSS THE
PLAINS...THERE IS A BRIEF PERIOD ALONG AND DIRECTLY BEHIND THE COLD
FRONT THAT SUPPORTS PRECIP. HOWEVER...THE LACK OF LLVL MOISTURE AND
LIFT IN THE NORTHWESTERLY SFC FLOW WILL KEEP SNOWFALL ACCUMULATIONS
BELOW A FEW INCHES TO THE EAST OF THE LARAMIE RANGE.
NORTHWESTERLY MIDLEVEL FLOW CONTINUES OVER THE AREA THROUGH
THURSDAY NIGHT. TEMPERATURES ON THURS WILL BE MUCH COOLER THAN
TODAY...AROUND 20 DEGREES...AS LLVL THICKNESSES DECREASE BEHIND
THE COLD FRONT. 700-500MB MOISTURE REMAINS PLENTIFUL ON
THURS...SO CAN NOT RULE OUT LIGHT SNOWFALL ACROSS THE SIERRA
MADRE/SNOWY RANGES...HOWEVER SNOWFALL RATES WILL BE MUCH LOWER
BEHIND THE SHORTWAVE AND ASSOCIATED MIDLEVEL FRONT.
LONG TERM...FRIDAY THROUGH WEDNESDAY
LOOKS LIKE WINDS CONTINUE TO BE STRONG FRIDAY AS SURFACE HIGH
PRESSURE BUILDS INTO THE AREA. GFS 700MB WINDS AROUND 40KTS OR SO
WITH 700MB HEIGHT GRADIENT RIGHT AROUND 60MTRS BETWEEN CRAIG AND
CASPER. THINK WE WILL STAY BELOW HEADLINE CRITERIA THROUGH THE DAY
FRIDAY...BUT WE MAY NEED TO WATCH SATURDAY THOUGH. UPPER RIDGE
PASSES EAST OF THE CWA FRIDAY NIGHT AND WINDS TURN MORE WESTERLY.
NEXT SHORTWAVE BEGINS APPROACHING SATURDAY MORNING INTO IDAHO.
700MB WINDS INCREASE ABOVE 50KTS AND CRAIG/CASPER GRADIENT BEGINS
TO CLIMB ABOVE 60MTRS BY 12Z SATURDAY MORNING.
GFS AND ECMWF COMING INTO AGREEMENT WITH THEIR SOLUTIONS ON A
STORM SYSTEM SATURDAY NIGHT INTO SUNDAY. BOTH MODELS ARE
SUGGESTING A MORE SOUTHERN TRACK OF THE UPPER LOW...HAVING THE LOW
TRACK ACROSS COLORADO. SURFACE LOW DEVELOPS OVER NORTHEASTERN
COLORADO SUNDAY MORNING...THEN BEGINS TO REALLY DEEPEN ACROSS
WESTERN NEBRASKA LATER SUNDAY MORNING. GFS SHOWING 850MB WINDS IN
THE PANHANDLE OF 40 TO 45KTS AND WRAP AROUND MOISTURE FROM THE LOW
LOOKS QUITE IMPRESSIVE ON THE GFS. ECMWF BRINGS THIS WRAP AROUND
MOISTURE FURTHER WEST INTO SOUTHEAST WYOMING. LOOKS LIKE WE MAY
NEED SOME WINTER HEADLINES IF THE MODELS CONTINUE THIS TREND AT
LEAST FOR THE PANHANDLE AND POSSIBLY FURTHER WEST.
REST OF THE EXTENDED LOOKS DRY FOR THE MOST PART...BUT COLD...WITH
700MB TEMPERATURES AROUND -14 TO -16C FOR MONDAY AND TUESDAY.
LOOKING AT HIGHS IN THE 30S WITH LOWS IN THE SINGLE DIGITS DURING
THIS TIME FRAME. MAY NEED TO GO LOWER DEPENDING ON SNOW PACK FROM
THE WEEKEND STORM.
FIRE WEATHER...
STRONG WINDS TO CONTINUE TODAY THROUGH THURSDAY BEFORE DECREASING
SOME THURSDAY EVENING INTO FRIDAY. A COLD FRONT DROPS INTO THE
AREA THURSDAY MORNING...BRINGING WIDESPREAD LIGHT SNOW TO MOST
LOCATIONS. FIRE WEATHER CONDITIONS WILL BE MINIMAL WITH EXISTING
SNOWPACK AND INCREASING SNOW CHANCES THURSDAY. ANOTHER CHANCE FOR
SNOW SUNDAY WITH SIGNIFICANT ACCUMULATIONS POSSIBLE.
