AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1158 AM MDT WED MAY 14 2014 .SHORT TERM...(TODAY THROUGH FRIDAY) ISSUED AT 337 AM MDT WED MAY 14 2014 CURRENT OBSERVATIONS SHOW A RELATIVELY COOL NIGHT TONIGHT WITH TEMPERATURES IN THE 20S AND 30S. A FEW UPPER TEENS HAVE BEEN OBSERVED OVER THE MORE SHELTERED LARAMIE VALLEY AS WELL EARLY THIS MORNING. OVERALL...TEMPERATURE FORECAST IS ON TRACK WITH A FREEZE WARNING CONTINUING FOR THE SOUTHERN NEBRASKA PANHANDLE. KCYS RADAR SHOWS A FEW LIGHT RAIN AND SNOW SHOWERS ALONG AND WEST OF THE LARAMIE RANGE. THIS ACTIVITY IS IN RESPONSE TO AN ACTIVE 250MB JET STREAK PUSHING SOUTHWARD...AND LIKELY INTENSIFYING THROUGH THE DAY BASED ON MODEL TRENDS. MODELS WERE NOT SHOWING THE JET BECOMING THIS INTENSE UNTIL THURSDAY...SO BELIEVE CHANCES FOR RAIN SHOWERS AND MAYBE SOME ISOLATED THUNDER WILL BE A LITTLE HIGHER TODAY FURTHER TO THE WEST ACROSS SOUTHEAST WYOMING. INCREASED POP FURTHER WEST TODAY...ESPECIALLY AS THE SURFACE COLD FRONT CURRENTLY ACROSS THE NORTHERN PLAINS PUSHES INTO THE REGION TODAY. THE SLOW WARMING TREND WILL CONTINUE TODAY...WITH TEMPERATURES IN THE 50S TO LOW 60 WEDNESDAY AFTERNOON...WARMEST OVER THE LOWER ELEVATIONS AND CHILLY OVER THE LARAMIE VALLEY. THURSDAY AND FRIDAY WILL BE VERY SIMILAR WEATHER WISE. MODELS SHOW THE NORTHERN BRANCH OF THE POLAR JET REMAIN OVER THE AREA AS A SERIES OF LOW PRESSURE CENTERS DEVELOPS ALONG THE COLD FRONT AND MOVE SOUTHWARD. MODELS INDICATE A BETTER CHANCE OF SHOWERS AND THUNDERSTORMS DUE TO THE ADDITIONAL LOW TO MIDLEVEL DYNAMICS AND MOISTURE ADVECTION. INCREASED POP BETWEEN 30 TO 60 PERCENT ACROSS SOUTHEAST WYOMING WHICH WILL HAVE AN AREA OF STRONG CONVERGENCE ALONG THE LARAMIE RANGE...ENHANCED BY UPSLOPE FLOW. LOWER POP AROUND 20 PERCENT EXPECTED ACROSS SOUTHWESTERN NEBRASKA SINCE THE FRONT WILL BE WELL TO THE WEST OF THAT AREA. SHOWER ACTIVITY MAY CONTINUE THROUGH THURSDAY NIGHT AS WELL. HIGH TEMPERATURES ON THURSDAY AND FRIDAY WILL REMAIN SLIGHTLY BELOW NORMAL...AND GENERALLY IN THE MID 50S TO MID 60S. THE WARMEST SPOT APPEARS TO BE WELL WEST OF THE LARAMIE RANGE WHERE SOUTH CENTRAL WYOMING MAY SEE TEMPERATURES AROUND 70 DEGREES BY FRIDAY AFTERNOON DUE TO THE POSITION OF THE SURFACE COLD FRONT. .LONG TERM...(THURSDAY THROUGH TUESDAY) ISSUED AT 430 AM MDT WED MAY 14 2014 NORTHWEST FLOW ALOFT WILL STILL BE IN PLACE FRIDAY NIGHT AS THE LARGE SLOWLY MOVING TROUGH SITS OVER THE WESTERN CONUS. THE TROUGH WILL MAKE SOME EASTWARD PROGRESS THIS WEEKEND WHILE A RIDGE STARTS TO SLIDE INTO THE ROCKIES. COOL AIR ALOFT AND SUBTLE SHORTWAVE RIPPLES AND 90-100KT UPPER JET WILL BRING A CHANCE FOR SHOWERS AND A FEW THUNDERSTORMS WITHIN NORTHWEST FLOW THURSDAY NIGHT INTO FRIDAY NIGHT. COULD SEE SOME LIGHT SNOW ACCUMULATIONS INTO THE HIGHER ELEVATIONS OF THE MOUNTAINS...OTHERWISE MAINLY LOOKING AT LIQUID PRECIPITATION. SATURDAY AND SUNDAY ARE SETTING UP TO BE NICE DAYS WITH TEMPERATURES CLOSER TO NORMAL AND MINIMAL CHANCES FOR PRECIPITATION. MONDAY SHOULD ALSO BE RATHER NICE DEPENDING ON HOW FAST THE NEXT TROUGH REACHES THE AREA. EXTENDED MODELS ARE SHOWING SIMILAR SOLUTIONS INTO EARLY AND EVEN MID NEXT WEEK WITH AND UPPER LEVEL LOW DROPPING INTO THE FOUR CORNERS AREA BEFORE BECOMING CUT OFF. EXACTLY WHERE THE LOW BECOMES CUT OFF WILL MAKE A BIG DIFFERENCE IN THE WEATHER TOWARD THE MIDDLE OF NEXT WEEK. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY MORNING) ISSUED AT 1152 AM MDT WED MAY 14 2014 THE MAIN CONCERN WITH THIS TAF ISSUANCE IS THE TIMING OF WHEN THE SHOWERS WILL MOVE THROUGH THE TAF SITES THIS AFTERNOON. LATEST RADAR LOOP WAS SHOWING SEVERAL SHOWERS STARTING TO DEVELOP OVER THE AREA. THE SHOWERS WILL BE QUICK HITTERS...AND MAY CAUSE SOME GUSTY WINDS...BUT VFR CEILINGS ARE PROGGED TO PREVAIL. GUSTY NORTHWEST WINDS SHOULD DIMINISH THIS EVENING...WITH MORE OF THE SAME WEATHER CONDITIONS EXPECTED TOMORROW. && .FIRE WEATHER... ISSUED AT 245 AM MDT WED MAY 14 2014 NO FIRE WEATHER CONCERNS THIS WEEK DUE TO RECENT WETTING RAINS AND NON CRITICAL FUELS. A WARMING TREND IS EXPECTED TO CONTINUE LATE THIS WEEK AND INTO THIS WEEKEND. SHOWERS AND THUNDERSTORMS WILL RETURN TO THE AREA BY THIS AFTERNOON AND CONTINUE THROUGH THIS WEEKEND AS A COOL FRONT STALLS ACROSS THE AREA. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
