Area forecast discussion, Jun 4, 12:07 PM MDT, 3 hours 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1207 PM MDT WED JUN 4 2014 .UPDATE... ISSUED AT 935 AM MDT WED JUN 4 2014 FORECAST LOOKS PRETTY WELL ON TRACK FOR TODAY. NO BIG UPDATES EXPECTED AT THIS TIME. FOLLOWING THE COLD FRONT LAST NIGHT AND LOW CLOUDS GENERALLY EAST OF THE LARAMIE RANGE THIS MORNING...IT WILL TAKE A WHILE TO DESTABILIZE TODAY. SHOULD SEE SOME CONVECTIVE CLOUDS DEVELOPING OVER THE MOUNTAINS BY EARLY THIS AFTERNOON...BUT STRONGER CONVECTION AND STORMS SHOULD HOLD OFF UNTIL MID TO LATE AFTERNOON. SHORTWAVE WILL MOVE INTO SOUTHEAST WYOMING LATE AFTERNOON TO EARLY EVENING. THIS WAVE WILL PROVIDE A BOOST TO UPWARD VERTICAL VELOCITIES CAUSING CONVECTION TO BECOME MORE ROBUST AND INCREASE THE COVERAGE. MODELS ALSO SHOWING A COLD FRONT DROPPING SOUTH ACROSS THE AREA THIS EVENING IN ASSOCIATION WITH THE SHORTWAVE. THIS ALSO COULD BE A FOCUS FOR ENHANCED CONVECTION THIS EVENING. SO BASICALLY THIS THUNDERSTORM EVENT SHOULD START OFF SLIGHTLY LATER THEN TYPICAL AND GO WELL INTO THE EVENING. SOME STORMS MAY EVEN CONTINUE AFTER MIDNIGHT...BUT THE SEVERE THREAT SHOULD BE LOW BY THAT TIME. WILL HAVE TO SEE WHAT THE ACTUAL CAPE VALUES AREA THIS AFTERNOON. CURRENTLY THE MODEL SHOWING 1000-2000 MU CAPE OVER THE NEBRASKA PANHANDLE LATE TODAY. THE BULK SHEAR VALUES ARE ON THE HIGH SIDE RANGING BETWEEN 40 TO 50 KTS...AND SOME BUFKIT SOUNDINGS SHOWING CLOSE TO 60 KTS. SHOULD CAPE VALUES RUN 2000 J/KG OR HIGHER...WILL AGAIN HAVE TO BE CONCERNED WITH VERY LARGE HAIL. NOT TOO EXCITED AT THIS POINT BUT GOLF BALL SIZE HAIL THAT IS CURRENTLY IN THE HWO LOOKS REASONABLE...BUT WILL STILL HAVE TO WATCH THE CAPE PROFILES LATER TODAY. && .SHORT TERM...(TODAY THROUGH FRIDAY) ISSUED AT 300 AM MDT WED JUN 4 2014 MORE CHANCES FOR SHOWERS AND THUNDERSTORMS THROUGH THE SHORT TERM. FORECAST CHALLENGES DEAL WITH SEVERITY AND LOCATION OF THESE STORMS. CURRENTLY...HAVE A FRONTAL BOUNDARY ALONG THE LARAMIE RANGE THIS MORNING SEPARATING DRY AIR TO THE WEST FROM REALLY MOIST AIR OUT OVER THE PANHANDLE. DEWPOINTS IN THE 50S WIDESPREAD ACROSS THE PANHANDLE WITH 28F BEING REPORTED AT RAWLINS AT 1AM. STRATUS SPREADING INTO AREAS EAST OF THE LARAMIE RANGE THIS MORNING AS EAST AND NORTHEAST WINDS CONTINUE OUT IN THE PANHANDLE. MOST REPORTING STATIONS DOWN IN THIS STRATUS...SETTING THE STAGE FOR LATER THIS AFTERNOON. STRATUS SHOULD BURN OFF BY MID TO LATE MORNING ACROSS THE PANHANDLE AND AREAS EAST OF THE LARAMIE RANGE. ANOTHER ROUND OF SEVERE THUNDERSTORMS EXPECTED THIS AFTERNOON. PARTICULARLY OUT IN THE PANHANDLE WHERE AFTERNOON SURFACE BASED CAPES WILL BE 1500 TO 2000 J/KG. SHEAR NOT AS GREAT TODAY COMPARED TO TUESDAY AFTERNOON...SO DO NOT THINK WE WILL SEE THE EXTREMELY LARGE HAIL THAT HIT LOCATIONS SUCH AS TORRINGTON AND BAYARD. BUT STILL COULD SEE GOLF BALL SIZED HAIL FROM THE MORE ROBUST STORMS. WILL ADD INTO THE MORNING HWO. NAM/WRF AND ECMWF CONCENTRATING THE HEAVIEST STORMS ACROSS THE NORTHERN PANHANDLE AND MAYBE INTO NIOBRARA COUNTY IN EAST CENTRAL WYOMING. WRF SIMULATED SATELLITE FORECAST HOWEVER HAS CELLS DEVELOPING OVER THE SOUTHERN PANHANDLE AS WELL WITH A PRETTY INTENSE CELL NEAR SIDNEY AT 21Z. THESE STORMS COULD LAST WELL INTO THE EVENING IF THE SIMULATED SATELLITE FORECAST PANS OUT. GET A LITTLE BREAK IN AFTERNOON THUNDERSTORMS FOR THURSDAY WITH MODELS PUSHING PRECIP SOUTH INTO COLORADO. GFS AND ECMWF BRINGING ANOTHER SHORTWAVE AND ASSOCIATED COLD FRONT INTO THE FORECAST AREA THURSDAY NIGHT INTO FRIDAY MORNING. GFS AND ECMWF HITTING THE PANHANDLE AND AREAS EAST OF THE LARAMIE RANGE PRETTY HARD FRIDAY AFTERNOON WITH AN INCH PLUS QPF OVER MUCH OF THE PANHANDLE. FORECAST STORM MOTIONS ON THE NAM SOUNDINGS OUT IN THE PANHANDLE UNDER 10KTS WITH LONG/SKINNY CAPE PROFILES...SO HEAVY RAIN CERTAINLY LOOKS POSSIBLE. WENT AHEAD AND ADDED SOME MENTION OF HEAVY RAIN IN THE FORECAST FOR THE PANHANDLE FRIDAY AFTERNOON. .LONG TERM...(FRIDAY NIGHT THROUGH TUESDAY) ISSUED AT 120 AM MDT WED JUN 4 2014 FRIDAY NIGHT...WITH COOL MOIST AIR SETTLING IN IN THE WAKE OF A COLD FRONT...AND A PASSING SHORTWAVE TROUGH ALOFT...WILL SEE SCATTERED TO NUMEROUS SHOWERS OVERNIGHT. SATURDAY...SCATTERED TO NUMEROUS SHOWERS...AND ISOLATED THUNDERSTORMS...WILL OCCUR IN THE COOL...MOIST AIR WITH A SHORTWAVE TROUGH ALOFT MOVING OVERHEAD NEAR PEAK HEATING. SUNDAY...LESS AREAL COVERAGE OF SHOWERS AND THUNDERSTORMS WITH LESS LOW AND MID LEVEL MOISTURE. MONDAY...ONLY ISOLATED LATE DAY SHOWERS AND THUNDERSTORMS EXPECTED NEAR THE MOUNTAINS AS A SHORTWAVE RIDGE ALOFT DEVELOPS OVERHEAD AND THE LOW AND MID LEVELS DRY OUT COMPARED TO SUNDAY. TUESDAY...CONTINUED RELATIVELY DRY WITH MINIMAL LOW AND MID LEVEL MOISTURE AND ZONAL FLOW ALOFT HELPING TO INDUCE SURFACE LEE TROUGHING AND WARM TEMPERATURES ALOFT ACTING AS A CAPPING INVERSION AND PRODUCING SIGNIFICANT CONVECTIVE INHIBITION...CIN. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY MORNING) ISSUED AT 1141 AM MDT WED JUN 4 2014 THE MAIN CONCERN THIS AFTERNOON IS THE CHANCE OF AFTERNOON THUNDERSTORMS DEVELOPING ONCE AGAIN. LATEST VISIBLE IMAGERY WAS SHOWING THE CUMULUS ENHANCING ALONG THE LARAMIE RANGE. THIS APPEARS TO BE ANOTHER SETUP FOR STRONG TO SEVERE CONVECTION THIS AFTERNOON ESPECIALLY IN THE PANHANDLE TAF SITES. 0-6KM SHEAR VALUES ARE GENERALLY AROUND 40 TO 50KTS WHICH IS FAVORABLE FOR SUPERCELLS ALONG WITH GOOD INSTABILITY WITH 1200-1700J/KG OF SURFACE BASED CAPE. GENERAL STORM MOTION WILL BE NORTHEAST AT 20 KTS...BUT RIGHT MOVERS WILL GENERALLY BE EAST AT 15 TO 20KTS. WOULD NOT BE SURPRISED TO SEE MORE LOW CLOUDS AND FOG DEVELOP OVERNIGHT AS THE BOUNDARY LAYER SATURATES ONCE AGAIN BEHIND THE WEAK FRONTAL BOUNDARY AND DRY LINE RETREATING. && .FIRE WEATHER... ISSUED AT 300 AM MDT WED JUN 4 2014 MINIMAL FIRE WEATHER CONCERNS AS SOUTHEAST WYOMING AND NEBRASKA PANHANDLE IN GREEN UP STAGE ON FUELS. DAILY CHANCES FOR SHOWERS AND THUNDERSTORMS EAST OF THE LARAMIE RANGE THROUGH THE WEEKEND. && .HYDROLOGY... ISSUED AT 300 AM MDT WED JUN 4 2014 RIVER FLOODING WILL CONTINUE ALONG THE UPPER NORTH PLATTE AND LARAMIE RIVERS OVER THE NEXT FEW DAYS. HOWEVER STAGES HAVE CRESTED AND ARE FORECASTED TO RECEDE. A DRY WEATHER PATTERN WILL EXIST FOR AREAS ALONG AND WEST OF THE LARAMIE RANGE THROUGH AT LEAST MIDWEEK SO NO WIDESPREAD RAINFALL EVENTS ARE EXPECTED. TEMPERATURES WILL BE SEASONAL...PRODUCING SOME SNOW MELT EACH DAY. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
