AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 405 AM CDT FRI AUG 3 2007 .DISCUSSION... HIGH PRESSURE LOCATED ACROSS NE NEB/NW IA THIS MORNING WITH E TO SE WINDS BRING A RETURN TO MUGGY UPPER 60S DEW PTS. NEXT TROF MOVING EAST ACROSS THE PANHANDLE OF NEB THIS MORNING. MODELS CONTINUE TO STRUGGLE WITH LOCATION OF THUNDERSTORM DEVELOPMENT...THUS POPS ARE THE MAIN CONCERN. LATEST RADAR IMAGES SHOW THUNDERSTORM ACTIVITY ON THE DECLINE...HOWEVER AM NOT EXPECTING THIS TREND TO CONTINUE ALL MORNING. AS THE WAVE REACTS WITH MORE LL MOISTURE...AND AS TEMPS INCREASE...DEVELOP OR STRENGTHENING OF SHOWERS TO BE EXPECTED. SURFACE LOW TO DEVELOP/MOVE ACROSS THE S DAKOTA/NEB BORDER THIS EVENING AND OVERNIGHT. SPIN AROUND THE LOW MAY CAUSE SOME STORMS TO SPIN...AND WILL HAVE TO KEEP AN EYE ON THIS. SPC DOES HAVE A SLIGHT RISK ACROSS THE NORTH...AND SEE NO REASON TO GO AGAINST. HEAVY RAIN WILL BE A CONCERN LATER TODAY AS MOISTURE CONTINUES TO INCREASE. LOW CONFIDENCE MODELS RAISE PW/S TO AROUND 2 INCHES TONIGHT...WHICH COULD LEAD TO LOCALLY VERY HEAVY RAINFALL. BEST CHANCE ACROSS NORTHERN CWA...WERE FF GUIDANCE HIGH AND WILL HOLD OF ANY HEADLINES. ACTIVITY PATTERN CONTINUES INTO NEXT WEEK AS WEAK WAVES TO CONTINUE TO MOVE ACROSS THE REGION. ALSO HIGH AMOUNTS OF LL MOISTURE EXPECTED TO BE RETAINED...THUS WILL NOT TAKE MUCH TO GET RAIN PRODUCING STORMS. && .AVIATION... EAST WIND ON NORTH SIDE OF THE SURFACE BOUNDARY IN NORTHERN KANSAS CONTINUES TO BRING LOW LEVEL MOISTURE ACROSS WESTERN AND NORTH CENTRAL NEBRASKA. AS A RESULT...INSTRUMENT CEILINGS ARE LIKELY IN CENTRAL AND SOUTHWEST NEBRASKA. THERE IS ALSO THE POSSIBILITY OF INSTRUMENT VISIBILITY...BUT FOR NOW WE WILL KEEP MARGINAL VISIBILITY IN THE NORTH PLATTE TERMINAL FORECAST WITH INSTRUMENT CEILINGS. TIMING OF THE ONSET OF THE LOW CEILINGS IS A BIT OF A COIN TOSS. CONDITIONAL CLIMATOLOGY INDICATES A 40 PERCENT OCCURRENCE OR HIGHER AFTER 09Z AND BELOW 40 PERCENT BY 14Z. THIS IS PRETTY MUCH WHAT IS REFLECTED IN THE LOW LEVEL MOISTURE PROGS AND SUBSEQUENTLY IN THE TERMINAL FORECAST FOR NORTH PLATTE. THE LOW LEVEL MOISTURE PROGS INDICATE THAT IT WILL NOT QUITE REACH THE VALENTINE AREA. && .LBF WATCHES/WARNINGS/ADVISORIES... NONE. && MASEK/JRS

AT THIS TIME...THE EXPECTED PATH OF THE CONVECTIVE SYSTEM IS ACROSS NORTH CENTRAL NEBRASKA. WITH ABUNDANT MOISTURE AND VERY WARM TEMPERATURES...ATMOSPHERIC CONDITIONS WILL BECOME VERY UNSTABLE. BY LATE EVENING...LOW LEVEL WIND FIELDS WILL SUPPORT THE DEVELOPMENT OF ISOLATED SUPER CELLS EMBEDDED IN THE LARGER CONVECTIVE SYSTEM. THE PRIMARY RISK WITH THE SUPER CELLS IS LARGE HAIL...THOUGH AND ISOLATED TORNADO IS POSSIBLE. OTHERWISE... VERY HEAVY RAIN IS LIKELY WITH THE CONVECTIVE SYSTEM. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
