Area forecast discussion, Aug 9, 2:00 PM MST, 5 hours 20 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 400 PM CDT MON AUG 9 2010 .SYNOPSIS... UPPER LEVEL RIDGE CENTERED OVER THE SE CONUS...WITH A TROF DIGGING INTO THE PAC NW. THIS PLACES THE HIGH PLAINS IN SOUTHWEST FLOW. A SHORT WAVE TROF IS CROSSING THE ROCKIES THIS AFTERNOON...WITH CONTINUING WARM MOIST AIR AHEAD OF IT...ACROSS THE PLAINS. AT THE SURFACE A NEARLY STATIONARY EAST/WEST BOUNDARY CONTINUES NEAR THE NEB/KS BORDER. && .SHORT TERM... FORECAST CONCERNS FOCUS ON POPS/PRECIP AMOUNT TONIGHT...THEN HEAT FOR MID WEEK. MAIN TROF ANALYZED ON H20 VAPOR IMAGERY CROSSING THE ROCKIES ATM...WILL CONTINUE TO TREK NE TOWARDS THE CWA. AHEAD OF THE TROF IS RICH MOISTURE WITH DEW PTS IN THE 60S AND LOW 70S...ALONG WITH TEMPS IN THE 80S TO LOWER 90S. THIS COMBINES WITH SOME STEEP LAPSE RATES TO PRODUCE CAPE VALUES GREATER THAN 3K J/KG BASED ON LATEST LAPS DATA. ALSO SEEING A WIND SHIFT LINE AND SOME CONVERGENCE ACROSS THE EASTERN PANHANDLE OF NEB. THIS BOUNDARY AND RICH MOISTURE HAS ALLOWED FOR SOME ISOLD STORMS TO DEVELOP ALREADY. EXPECT THIS ACTIVITY TO CONTINUE AND INCREASE IN COVERAGE WHEN THE MAIN TROF ARRIVES. SOME SEVERE WEATHER IS POSSIBLE ALTHOUGH WITH A WEAKLY SHEERED ENVIRONMENT PRESENT NOT EXPECTING A MAJOR OUTBREAK. MAIN THREAT IS FOR WINDS AND HAIL...HOWEVER NEAR THE BOUNDARY...WHICH IS BEGINNING TO LIFT NORTH AS A WARM FRONT TOWARDS THE I80 CORRIDOR...AN ISOLD TOR CANNOT BE RULED OUT. OVERNIGHT THE STORMS EXPECTED TO CONGEAL INTO A COMPLEX. WITH PW/S NEARING 2 INCHES...EXPECT SOME HEAVY RAIN. PLACEMENT OF THE COMPLEX VARIES BY THE DIFFERENT MODELS FROM WESTERN...TO CENTRAL NEB. IF THE TRACK GOES MORE CENTRAL...THEN PORTIONS OF N CENTRAL WILL NEED TO BE WATCHED CAREFULLY FOR FLASH FLOODING. WARM FRONT EXPECTED TO PUSH NORTHEAST AS RIDGE RETROGRADES WEST. THIS WILL PUSH ACTIVITY MAINLY TO THE NORTH AND PUT WESTERN AND N CENTRAL NEB BACK IN MORE ZONAL FLOW. AFTER SOME LINGERING CHANCES TOMORROW...WAVE SLIDES EAST AND THE HEAT TURNS ON. BY WED AND THURS...HIGHS PUSH IN THE MID AND UPPER 90S. UPPER LEVEL DISTURBANCES SHOULD PUSH ACROSS TO THE NORTH WITH MOST OF THE CWA DRY...AS NEXT COLD FRONT DIPS INTO THE PAC NORTHWEST FOR THURS. .LONG TERM... MED RANGE OPERATIONAL AND ENSEMBLE GUIDANCE IN MUCH BETTER AGREEMENT THAN 24 HOURS AGO...THOUGH SCENARIO WITH RETROGRADING NW TROF INTO REX PATTERN HAS BEEN SQUASHED. COOL DOWN FOR THE CWA AND ADJACENT PLAINS LOOKING BETTER WITH LARGE SCALE TROF DROPPING FROM THE HIGH LATITUDES INTO NC CONUS THIS WEEKEND. FRIDAY STILL THE MOST PROBLEMATIC WITH TIMING OF THE INITIAL COLD FRONT THROUGH THE HIGH PLAINS INTO THE MO VALLEY REGION. GFS MOST DRASTIC CHANGE FROM 24 HOURS AGO...BUT IS STILL ON THE SLOWER SIDE OF MODEL GROUPINGS. THE FASTER SOLN WOULD DROP TEMPERATURES ON FRIDAY WELL INTO THE 80S WITH ISENTROPIC LIFT AIDING IN AFTERNOON CONVECTION FRIDAY AS WELL. FAVORED SOLN FROM HPC IS WITH THE FASTER SOLN BACKED UP BY ENSEMBLE GROUPINGS AND TWEAKED FORECAST DOWN A FEW DEGREES FOR FRIDAY ADJUSTED WINDS FOR AN AFTERNOON FROPA. MAY BE SOME DAY 2 FROPA UPSLOPE PCPN IN THE SOUTHWEST ON SATURDAY...BUT OTHERWISE A COOLER AND DRIER FORECAST...ESPECIALLY HUMIDITY WISE...WILL BE ON TAP. && .AVIATION... CONVECTION BLOOMING ACROSS THE HIGH PLAINS THIS AFTERNOON AND THIS TREND SHOULD CONTINUE THROUGH THE EVENING AND OVERNIGHT HOURS. CONFIDENCE HIGHEST FOR A THUNDERSTORM IN VCNTY OF KLBF TERMINAL TOWARD THE MIDDLE TO LATE EVENING HOURS...WITH LESS CONFIDENCE OF A STORM IN VCNTY OF KVTN HAVE ONLY PLACE A PROB 30 GROUP. THESE STORMS WILL ALL HAVE THE CAPABILITY OF PRODUCING LOWERED FLIGHT CONDITIONS IN HEAVY RAIN...POSSIBLY SMALL HAIL AND DANGEROUS WIND CONDITIONS. THE CONVECTIVE ACTIVITY MAY PERSIST IN THE VCNTY OF THE KLBF TERMINAL WELL INTO THE EARLY MORNING HOURS. VFR CONDITIONS ARE EXPECTED BY SUNRISE ACROSS THE REGION...THOUGH HEAVY RAINFALL MAY LEAD TO LIGHT FOG FORMATION IN THE PLATTE RIVER VALLEY AS WINDS BECOME LIGHT AND VARIABLE TOMORROW MORNING. && .LBF WATCHES/WARNINGS/ADVISORIES...NONE. && SYNOPSIS/SHORT TERM...MASEK LONG TERM/AVIATION...13
