Area forecast discussion, Aug 1, 2:03 PM MST, 2 hours 12 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 303 PM MDT THU AUG 1 2013 .SHORT TERM...(THIS EVENING THROUGH SATURDAY NIGHT) ISSUED AT 302 PM MDT THU AUG 1 2013 ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS TODAY AND TONIGHT WITH SOME SEVERE THUNDERSTORMS EXPECTED. DEVELOPMENT HAS ALREADY OCCURRED OVER WESTERN PORTIONS OF THE FORECAST AREA. BATCH OF SHOWERS AND THUNDERSTORMS CURRENTLY OVER ALBANY COUNTY WILL SPREAD EAST INTO THE PLAINS OVER THE NEXT FEW HOURS. THIS CONVECTION SHOULD HELP ERODE IF NOT BREAK THE CAP. AT ANY RATE...SHOULD SEE THE CAP BREAK SOMETIME THIS AFTERNOON WITH STORMS DEVELOPING AND EVENTUALLY BECOMING SEVERE. MAIN SEVERE WEATHER THREAT WILL BE LARGE HAIL BUT DAMAGING WINDS AND A FEW TORNADOES ARE POSSIBLE LATE THIS AFTERNOON AND EVENING. VERY JUICY AIR IN PLACE AT THIS TIME WITH DEW POINTS MAINLY IN THE 50S TO LOW 60S EAST OF THE LARAMIE RANGE. THE ONE EXCEPTION BEING AROUND CHEYENNE WHERE A DRY PUNCH DROPPED THE DEW POINTS INTO THE 30S. MU CAPES FROM CURRENT ANALYSIS RUNNING BETWEEN 2000-3000 J/KG...NEARLY DOUBLE THAT OF YESTERDAY BUT WIND PROFILES ARE SIMILAR. IMPRESSIVE DEEP LAYER SHEAR WITH INCREASING WINDS FROM THE BOUNDARY LAYER THROUGH THE EQUILIBRIUM LEVEL. THIS WILL SUPPORT SUPER-CELL THUNDERSTORMS WITH STRONG UPDRAFTS. HAIL SIZES COULD BE VERY LARGE...CERTAINLY HAIL OVER 2 INCHES IS POSSIBLE AND COULD SEE A FEW STORMS PRODUCING BASEBALL SIZED HAIL. WIND THREAT APPEARS TO BE RATHER STANDARD WITH 60-70 MPH WINDS. ALSO...THERE IS A CHANCE FOR TORNADOES. CURRENTLY A COUPLE BOUNDARIES IN PLACE OVER THE AREA WHICH COULD BE A FOCUS FOR TORNADIC DEVELOPMENT. ALSO EASTERLY SURFACE WINDS ARE FORECAST TO INCREASE TO 10 TO 15 MPH BY THIS EVENING. THIS COULD ENHANCE THE TORNADO THREAT FOR A TIME THIS EVENING. THE HIGHEST TORNADIC THREAT APPEARS TO BE NEAR A SYNOPTIC BOUNDARY IN THE NORTHERN NEBRASKA PANHANDLE AND ADJACENT PORTIONS OF EAST CENTRAL WY EARLY THIS EVENING. MODELS ARE NOW PUSHING THE MAIN AREA OF LOW LEVEL MOISTURE AND INSTABILITY EAST OF THE FORECAST AREA FOR TOMORROW. THIS WILL SIGNIFICANTLY REDUCE THE SEVERE THUNDERSTORM POTENTIAL FOR FRIDAY. MAINLY GARDEN VARIETY SHOWERS AND THUNDERSTORMS FRIDAY WITH THE ONLY POTENTIAL FOR SEVERE MAY BE THE NORTHERN NEBRASKA PANHANDLE BUT THAT DEVELOP ON WHERE THE LOW LEVEL BOUNDARY RESIDES. BOUNDARY IS FORECAST TO SLAM BACK TO THE WEST FRIDAY NIGHT. COULD SEE SOME FOG AND LOW CLOUDS EAST OF THE LARAMIE RANGE AS THE LOW LEVEL MOISTURE INCREASES. MORE SHOWERS AND THUNDERSTORMS SATURDAY AFTERNOON BUT TOUGH TO GUAGE THE STRENGTH AT THIS POINT...BUT BASED ON CURRENT MODELS COULD SEE A FEW MORE SEVERE THUNDERSTORMS. .LONG TERM...(SUNDAY THROUGH THURSDAY) ISSUED AT 302 PM MDT THU AUG 1 2013 AN UPPER RIDGE IS EXPECTED TO HOLD JUST WEST OF THE CWA FOR MUCH OF THIS PERIOD...EXTENDING BASICALLY FROM TEXAS NNW JUST WEST OF THE ROCKY MOUNTAIN CHAIN. SUBTROPICAL MOISTURE WILL CONTINUE TO MOVE UNDER THIS RIDGE FROM THE DESERT SW ACROSS THE REGION WHICH WILL KEEP AT LEAST WIDELY SCTD MAINLY AFTERNOON AND EVENING CONVECTION GOING ACROSS THE CWA THROUGH SUNDAY THEN IT MIGHT BECOME MORE ISOLATED EARLY NEXT WEEK AS THE MOISTURE DECREASES A BIT. A DECENT PUSH OF COOLER AIR IS DEPICTED TO MOVE INTO THE REGION MIDWEEK AND SHOULD ALLOW FOR MORE WIDESPREAD SHOWERS AND STORMS WITH RESULTANT UPSLOPE PATTERN. GFS MAY BE OVERDONE WITH ITS QPF BUT AT LEAST SCTD POPS LOOK IN ORDER THEN. TEMPERATURES WARM SUNDAY THROUGH TUESDAY BEFORE TRENDING DOWN WEDNESDAY. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY MORNING) ISSUED AT 1118 AM MDT THU AUG 1 2013 VFR SHOULD PREVAIL OVER THE AREA THROUGH FRIDAY MORNING. A WEAK SFC BOUNDARY WILL MOVE INTO EAST CENTRAL WY INTO THE SOUTHERN NEB PANHANDLE THIS AFTERNOON. SCTD SHOWERS AND TSTRMS EXPECTED TO FORM OVER THE AREA THIS AFTERNOON AND MOVE EAST THROUGH THIS EVENING. BRIEF MVFR CIGS AND GUSTY WINDS POSSIBLE AROUND THESE STORMS. && .FIRE WEATHER...
