NWS Cheyenne, WY wrote its last area forecast discussion before the first event at Mar 29, 8:14 AM MST, 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 914 AM MDT SAT MAR 29 2014 .UPDATE... ISSUED AT 901 AM MDT SAT MAR 29 2014 WILL HAVE TO KEEP A CLOSE EYE ON WIND SPEEDS IN THE ARLINGTON AREA TODAY. WINDS HAVE GUSTED AS HIGH AS 57 MPH AT THE ARLINGTON WY DOT SITE WITH OTHER SITES GUSTING 50 TO 55 MPH. MODELS DO SHOWING WINDS ALOFT INCREASING SLIGHTLY THIS AFTERNOON BUT NOT AS STRONG OF SUBSIDENCE. AT THIS TIME WILL HOLD OFF ON ANY HEADLINES AS WINDS SHOULD BE MARGINAL FOR A HIGH WIND WARNING AND RELATIVELY LOCALIZED. UPDATED THE SKY GRIDS AS THE STANDING WAVE CLOUDS IS IN PLACE ALONG AND EAST OF THE LARAMIE RANGE. MODELS INDICATE THE WAVE COULD WILL THIN OUT THIS AFTERNOON. SHOULD NOT SEE A BIG IMPACT ON TEMPERATURES TODAY BUT IT WILL BE A SLOWER RISE IN TEMPERATURES AND COULD END UP A FEW DEGREES BELOW THE CURRENT FORECAST WHERE THE WAVE CLOUD HANGS ON THE LONGEST. OTHERWISE FORECAST IN GOOD SHAPE. && .SHORT TERM...(TODAY AND TONIGHT) MAIN WEATHER STORIES THROUGH THIS EVENING WILL BE THE WARM TEMPERATURES AND ASSOCIATED FIRE WEATHER CONCERNS AND THE WINDY CONDITIONS ALONG AND WEST OF THE LARAMIE RANGE. HIGHS THIS AFTN ARE STILL EXPECTED TO CLIMB INTO THE 60S AND LOWER 70S ACROSS THE PLAINS. MAIN CHANGE TO THE FCST GRIDS FOR THIS AFTN WAS TO DECREASE DEWPOINTS...ESPECIALLY STRETCHING FROM LARAMIE COUNTY INTO THE SOUTHERN PANHANDLE. DEEP SOUTHWESTERLY FLOW IN THE LOW-TO-MIDLEVELS WILL COMBINE WITH EXCELLENT SOLAR INSULATION TO PRODUCE DEEP LLVL MIXING THIS AFTN AND IT IS THESE CONDITIONS THAT MOS OFTEN GROSSLY UNDERESTIMATES AFTN DEWPOINTS. WENT WITH A BLEND OF THE DRIER MAV AND RUC GUIDANCE AND THIS RESULTS IN MIN RH VALUES IN THE 10-15 PERCENT RANGE OVER THE PANHANDLE. EXCELLENT MIXING WILL TAP INTO 25-30 KTS AT THE TOP OF THE MIXED LAYER. THUS...DECIDED TO ISSUE A RFW FOR THE ENTIRE PANHANDLE. THE NEXT ITEM OF CONCERN IS WINDS TO THE WEST OF THE LARAMIE RANGE. THE GFS SHOWS 700MB WINDS OF 40-45 KTS FROM 18-00Z AND THE 700MB CAG-CPR GRADIENT IS AROUND 45 METERS. CONTEMPLATED PUTTING THE ARLINGTON AREA IN A HIGH WIND WARNING FOR THE AFTN...HOWEVER WOULD LIKE TO SEE THE LLVL GRADIENT AND WINDS ALOFT A BIT STRONGER. WILL LIKELY SEE GUSTS AROUND 45 KTS IN THE ARLINGTON AREA WITH THE FAVORABLE GAP WINDS. OUTSIDE OF ARLINGTON...COULD SEE GUSTS TO 40 KTS DURING PEAK MIXING. THE LLVL GRADIENT COMES DOWN BY THIS EVENING AND FLOW ALOFT BECOMES MORE SOUTHWESTERLY...SO WILL SEE WINDS DECREASE. ANOTHER WARM DAY ON SUNDAY AHEAD OF A SHORTWAVE. KEPT A SLIGHT CHANCE OF AFTN TSTMS IN THE FCST AS BOTH THE GFS AND NAM INDICATE LIFTED INDICES OF 0C TO -1C. MODELS CONTINUE TO INDICATE THAT THE UPPER LEVEL SYSTEM WILL MOVE DIRECTLY OVERHEAD ON SUNDAY NIGHT WITH A FROPA AFTER 06Z MON. BEST UPPER LEVEL DIVERGENCE AND LARGE SCALE LIFT IS LARGELY OFF TO THE NORTHEAST OF THE CWA...HOWEVER MAY HAVE TO WATCH THE NORTHEAST ZONES FOR ADVISORY AMOUNTS. THIS AREA WILL BE CLOSEST TO THE WESTERN EDGE OF A DEVELOPING TROWAL/FRONTOGENESIS FEATURE OVER SOUTH DAKOTA. JUST SOMETHING TO WATCH IN FUTURE MODEL RUNS. .LONG TERM...(EARLY TUESDAY MORNING THROUGH FRIDAY) ISSUED AT 445 AM MDT SAT MAR 29 2014 MAIN FORECAST CONCERN NEXT WEEK WILL BE A SLOW MOVING UPPER LEVEL LOW MOVING ACROSS THE GREAT BASIN REGION AND INTO THE ROCKY MOUNTAINS BY WEDNESDAY. ALTHOUGH MODELS ARE IN POOR AGREEMENT WITH THIS SYSTEM AND HAVE BEEN OVER THE LAST 48 HOURS...THERE IS STILL CONCERN OVER A POTENTIAL SIGNIFICANT STORM OVER PORTIONS OF THE HIGH PLAINS. FOR TUESDAY...ALL MODELS NOW SHOW THE COLD FRONT FROM SUNDAYS SYSTEM ALONG THE CONTINENTAL DIVIDE...RETREATING EASTWARD AS A WARM FRONT. WARM AIR ADVECTION ALOFT AND COOL UPSLOPE FLOW WILL COMBINE TO PRODUCE OVERRUNNING PRECIPITATION IN THE FORM OF SNOW ACROSS THE FORECAST AREA. INCREASED POP BETWEEN 30 TO 50 PERCENT ACROSS MOST OF THE FORECAST AREA WITH THE EXCEPTION OF EXTREME EASTERN ZONES ACROSS THE SOUTHERN NEBRASKA PANHANDLE. 1 TO 2 INCHES OF SNOW LOOKS POSSIBLE WITH THIS INITIAL OVERRUNNING EVENT TUESDAY...ESPECIALLY NORTH OF I80. AS THE WARM FRONT LIFTS NORTHEAST DURING THE DAY...THE SNOW WILL QUICKLY MELT AND/OR CHANGE TO RAIN AS TEMPERATURES INCREASE INTO THE 50S. ATTENTION THEN SHIFTS WESTWARD TUESDAY NIGHT AS THE MAIN UPPER LEVEL LOW MOVES ACROSS THE GREAT BASIN. MODELS ARE STRUGGLING WITH THE PLACEMENT...MOVEMENT...AND POTENTIAL EVOLUTION OF A STRONG WINTER STORM. ALL MODELS INDICATE A BRIEF BREAK EARLY WEDNESDAY BEFORE THE UPPER LEVEL LOW MOVES INTO THE ROCKY MOUNTAIN REGION AND ATTEMPTS TO BECOME BETTER ORGANIZED. THE ECMWF SHOWS A RATHER DISORGANIZED STORM SYSTEM...WITH THE MAIN LOW EJECTING NORTHEAST AND THEN DRIFTING EASTWARD INTO THE DAKOTAS...WHILE THE SOUTHERN ENERGY PUSHES INTO THE GREAT PLAINS AND THEN INITIATES STRONG CYCLOGENESIS IN KANSAS/MISSOURI LATE WEDNESDAY NIGHT. THE ECMWF INDICATES SPLIT FLOW ACROSS SOUTHEAST WYOMING WITH LIGHT SNOW ACCUMULATIONS NEAR I80 DUE TO THE SOUTHERN WAVE...AND LIGHT SNOW ACROSS CENTRAL WYOMING DUE TO THE MAIN LOW WITH LITTLE IN BETWEEN. THE GEM IS THE MOST AGGRESSIVE...SHOWING A COLORADO LOW SLOWLY EJECTING NORTHEAST FROM THE FOUR CORNERS REGION. THIS SCENARIO RESULTS IN WIDESPREAD MODERATE TO HEAVY SNOWFALL ACROSS THE FORECAST AREA BEGINNING WEDNESDAY EVENING AND LASTING THROUGH THURSDAY. THE 00Z GFS WAS CONSIDERABLY FURTHER SOUTH...WITH THE I80 CORRIDOR GETTING CLIPPED BY LIGHT SNOWFALL. HOWEVER...THE 06Z GFS IS FURTHER NORTH CLOSER TO THE GEM. MOST OF THE ENSEMBLE FORECASTS WERE IN BETWEEN THE GEM AND GFS LAST NIGHT...SO KEPT POP BETWEEN 25 TO 40 PERCENT OVER THE LOWER ELEVATIONS WITH POP NEAR 70 PERCENT IN THE MOUNTAINS THROUGH THURSDAY EVENING. WILL CONTINUE TO CLOSELY MONITOR THIS SYSTEM THROUGH THIS WEEKEND AND EARLY NEXT WEEK FOR CHANGES...BUT A SIGNIFICANT STORM SYSTEM APPEARS POSSIBLE NEXT WEEK. LOWERED TEMPERATURES BELOW NORMAL WEDNESDAY THROUGH FRIDAY. A WEAK RIDGE OF HIGH PRESSURE WILL BUILD ACROSS THE AREA ON FRIDAY...WITH DRIER CONDITIONS EXPECTED. && .AVIATION...(FOR THE 12Z TAFS THROUGH LATE TONIGHT) ISSUED AT 345 AM MDT SAT MAR 29 2014 VFR CONDITIONS EXPECTED TODAY AND TONIGHT WITH MOSTLY CLEAR SKIES. WINDY CONDITIONS WILL RETURN TO SOUTHEAST WYOMING AFTER 15Z TODAY WITH GUSTS UP TO 45 KNOTS POSSIBLE ALONG AND WEST OF THE LARAMIE RANGE. IT WILL BE BREEZY ACROSS WESTERN NEBRASKA WITH GUSTS UP TO 30 KNOTS AT TIMES THIS AFTERNOON. && .FIRE WEATHER... ISSUED AT 414 AM MDT SAT MAR 29 2014 A WARM AND DRY AIRMASS WILL BE IN PLACE OVER THE REGION THROUGH THE WEEKEND. HIGHS WILL BE 10-15 DEGREES ABOVE NORMAL. MINIMUM HUMIDITY VALUES WILL FALL INTO THE 10-15 PERCENT RANGE OVER THE NEBRASKA PANHANDLE THIS AFTERNOON AND WILL COMBINE WITH GUSTY SOUTHWEST WINDS TO PRODUCE CRITICAL FIRE WEATHER CONDITIONS. A RED FLAG WARNING IS IN EFFECT THIS AFTERNOON FOR THE PANHANDLE SINCE FUELS ARE CONDUCIVE TO FIRE GROWTH IN THAT REGION. WHILE HUMIDITY VALUES WILL BE SIMILAR ON SUNDAY AFTERNOON...WIND SPEEDS SHOULD BE LESS SO ONLY AN ELEVATED FIRE WEATHER THREAT IS EXPECTED. COOLER TEMPERATURES WILL OCCUR ON MONDAY BEHIND A COLD FRONT THAT WILL PASS OVER THE REGION ON SUNDAY NIGHT. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
