NWS Cheyenne, WY wrote its last area forecast discussion before the first event at Feb 23, 10:59 PM MST, 4 hours 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1059 PM MST TUE FEB 23 2016 .SHORT TERM...(THIS EVENING THROUGH THURSDAY NIGHT) ISSUED AT 258 PM MST TUE FEB 23 2016 THE MAIN CONCERN WITH THIS FORECAST PACKAGE IS THE WIND POTENTIAL TONIGHT AND TOMORROW. TONIGHT: LATEST SURFACE ANALYSIS WAS SHOWING FAIRLY GOOD PRESSURE FALLS TAKING PLACE IN EASTERN WYOMING IN ASSOCIATION WITH A SURFACE TROF IN CENTRAL WYOMING. LATEST WATER VAPOR LOOP WAS SHOWING A POTENTIAL VORTICITY ANOMALY IN SOUTHERN CANADA ASSOCIATED WITH A 110KT JET STREAK MOVING THROUGH WESTERN WYOMING. AS THIS POTENTIAL VORTICITY ANOMALY MOVES SOUTHEAST INTO THE NORTHERN PLAINS...IT WILL DRIVE A FRONTAL BOUNDARY SOUTHEAST TONIGHT. AHEAD OF THIS FRONT...WIND SPEEDS WILL BE ON THE INCREASE ACROSS OUR WIND PRONE AREAS. THE MOST WINDY LOCATION LOOKS TO BE NEAR BORDEAUX SINCE THE PRESSURE GRADIENT WILL BE TIGHTER IN THAT REGION ALONG WITH A TIGHT MSLP GRADIENT. THIS IS A GOOD SETUP FOR BORDEAUX TO RECEIVE STRONG WINDS TONIGHT WITH SPEEDS OF 55 TO 65 MPH ESPECIALLY AROUND DAYBREAK. AS A RESULT...WE WENT AHEAD AND ISSUED A HIGH WIND WARNING FOR THAT AREA. IT IS ALSO EXPECTED TO BE WINDY ALONG THE LARAMIE RANGE FOOTHILLS AND ARLINGTON TONIGHT...BUT WE HAVE DECIDED TO HOLD BACK ON THAT AREA FOR NOW...DUE TO LACK OF PRESSURE GRADIENT. WEDNESDAY-THURSDAY NIGHT: AFTER THE FRONTAL BOUNDARY MOVES THROUGH THE AREA TOMORROW MORNING...THERE IS SOME GOOD POTENTIAL FOR MIXING ESPECIALLY IN THE NEBRASKA PANHANDLE AND AREAS ALONG I-80. LATER SHIFTS MAY NEED TO CONSIDER THE POTENTIAL FOR A WIND ADVISORY IN THE NEBRASKA PANHANDLE ON WEDNESDAY. OTHERWISE...WIND SPEEDS SHOULD BEGIN TO TAPER OFF DURING THE EVENING WITH LIGHT WINDS EXPECTED OVERNIGHT WHICH SHOULD ALLOW TEMPERATURES TO TUMBLE INTO THE TEENS. A WARMING TREND IS EXPECTED ON THURSDAY AS THE UPPER LEVEL RIDGE BEGINS TO BUILD OVER THE AREA WHICH SHOULD ALLOW AFTERNOON HIGHS TO REACH THE 40S. .LONG TERM...(FRIDAY THROUGH TUESDAY) ISSUED AT 258 PM MST TUE FEB 23 2016 FRIDAY...NICE WARMING TREND ON TAP WITH FORECAST HEIGHT AND THICKNESS RISES AS THE UPPER RIDGE AXIS MOVES TO THE WESTERN WYOMING STATE LINE. SATURDAY...PROGRESSIVE RIDGE ALOFT MOVES OVERHEAD IN ADVANCE OF THE NEXT APPROACHING SHORTWAVE TROUGH ALOFT OVER WESTERN WYOMING IN THE AFTERNOON. CONTINUED MILD IN THE WARM SECTOR AHEAD OF THE SHORTWAVE WITH HIGHS INTO THE 60S EAST OF INTERSTATE 25. MODELS LOOK A BIT OVERDONE ON QPF AND THUS WILL KEEP ONLY ISOLATED LATE AFTERNOON SHOWERS OVER OUR SNOWY AND SIERRA MADRE RANGES...WITH DRY ELSEWHERE. SUNDAY...COOLER DAY IN THE WAKE OF THE SHORTWAVE TROUGH ALOFT AND ITS ASSOCIATED COLD FRONT. WINDY PER PROGGED LOW AND MID LEVEL GRADIENTS. CHANCES FOR PRECIPITATION EARLY IN THE DAY WITH THE TROUGH PASSAGE AND COLD FRONTAL PASSAGE. MONDAY...PROGRESSIVE PATTERN CONTINUES WITH THE GFS SHOWING A SHORTWAVE RIDGE ALOFT OVER EASTERN WYOMING WITH NEXT SHORTWAVE TROUGH ALOFT APPROACHING WESTERN WYOMING IN THE AFTERNOON. THE 12Z ECMWF...HOWEVER...HAS THE SHORTWAVE TROUGH ALOFT OVER EASTERN WYOMING WITH COLD FRONTAL PASSAGE DURING THE DAY. NOT SURE WHICH MODEL WILL BE CORRECT...SO WILL BLEND OUR FORECAST WITH OUR NEIGHBORING OFFICES AND KEEP LOW CHANCES FOR POPS ACROSS OUR SNOWY AND SIERRA MADRE RANGES. DRY ELSEWHERE. TUESDAY...RELATIVELY SIGNIFICANT TIMING DIFFERENCES BETWEEN THE MODELS ON SYNOPTICS...SO UNCERTAINTY IN THEIR SOLUTIONS IS HIGH. FOR NOW...WILL BLEND AND PAINT LOW CHANCE POPS IN SOME LOCATIONS AND KEEP HIGH TEMPERATURES IN THE 40S AT LOWER ELEVATIONS...WITH 30S IN THE MOUNTAINS. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z WEDNESDAY NIGHT) ISSUED AT 1057 PM MST TUE FEB 23 2016 VFR CONDITIONS THROUGH THE TAF PERIOD. NORTHWEST WINDS WILL INCREASE BY LATE WED MORNING...MOSTLY TO THE EAST OF THE LARAMIE RANGE. GUSTS TO 25-35 KTS WILL BE POSSIBLE THROUGH THE AFTERNOON. && .FIRE WEATHER... ISSUED AT 322 PM MST TUE FEB 23 2016 GUSTY WINDS ARE EXPECTED ON WEDNESDAY MAINLY ALONG AND EAST OF INTERSTATE 80...BUT RELATIVE HUMIDITIES WILL STILL BE HIGH ENOUGH TO PREVENT FIRE GROWTH. NO FIRE WEATHER CONCERNS THROUGH THE REMAINDER OF THE WORK WEEK BUT WILL HAVE TO KEEP AN EYE ON SATURDAY. TEMPERATURES WILL WARM INTO THE 60S ACROSS THE PLAINS ON SATURDAY. THIS WILL OCCUR ALONG WITH GUSTY WEST WINDS AND HUMIDITY VALUES INTO THE 20S...AND POSSIBLY THE TEENS. SO NEAR CRITICAL FIRE WEATHER CONDITIONS LIKELY. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...HIGH WIND WARNING UNTIL 11 AM MST WEDNESDAY FOR WYZ106. NE...NONE. && SHORT TERM...REC LONG TERM...RUBIN AVIATION...ZF
