AREA FORECAST DISCUSSION...CORRECTED TYPO IN 1ST PARAGRAPH. NATIONAL WEATHER SERVICE NORTH PLATTE NE 340 AM CDT THU AUG 5 2010 .DISCUSSION... SREF/NAM/GFS SEEM TO BE OVERDOING IT ON THE PRECIP THIS MORNING...BUT AS AN UPPER LEVEL WAVE MOVES EAST TOWARD THE AREA EARLY THIS MORNING CANNOT RULE OUT ISOLATED DEVELOPMENT...AND WILL KEEP THE THREAT FOR ISOLATED SHWRS/TSTMS AREA WIDE. LATER THIS AFTERNOON...WEAK MOIST UPSLOPE FLOW...COMBINED WITH STEEP LOW LEVEL LAPSE RATES AND CONVERGENCE IN AREA OF WEAK LOW PRESSURE DEVELOPMENT ACROSS THE HIGH PLAINS...MAY BE ENOUGH TO SPARK SCATTERED TSTMS ACROSS THE WESTERN THIRD OF NEB. SFC BASED CAPE VALUES APPROACH 2000 J/KG ALONG WITH 35 KTS OF 0-6 KM BULK SHEAR...SO A SUPERCELL OR TWO IS POSSIBLE. SPC HAS MUCH OF THE SOUTHWEST INTO SOUTHERN NEB PANHANDLE IN A SLIGHT RISK FOR SEVERE...AND BASED ON THE LOW AND MID LEVEL LAPSE RATES...THIS AREA SEEMS MOST AT RISK FOR A STRONG OR SEVERE STORM. A FEW STORMS MAY THEN LINGER INTO THE EVENING ACROSS SOUTHWEST NEB. OTHERWISE...BASED OFF OF EARLY MORNING SATELLITE IMAGERY...FEEL MODELS MAY BE A LITTLE BULLISH ON CLOUD COVER TODAY AND WENT 1 TO 3 DEGREES WARMER THAN GUIDANCE. THIS PUTS HIGHS ACROSS THE BOARD IN THE LOWER TO MID 80S. FRIDAY AND SATURDAY...LOOK FOR A SLIGHT CHANCE FOR TSTMS FRIDAY AFTERNOON AS MOISTURE AND INSTABILITY INTERACT WITH SOME WEAK CONVERGENT BOUNDARIES. THE BETTER CHANCE FOR STORMS /30 PERCENT/ COMES FRIDAY NIGHT AS THE GFS INDICATES STRONG MID LEVEL WAA...ALONG WITH A HEALTHY H85 S-SWLY LLJ. A LINGERING STORM IS POSSIBLE EARLY SATURDAY MORNING ACROSS THE NORTHEAST...WITH THE REMAINDER OF THE DAY DRY FOR ALL AREAS. SATURDAY NIGHT INTO NEXT WEEK...THE UPPER LEVEL RIDGE OF HIGH PRESSURE ATTEMPTS TO BUILD NORTH AND WEST FROM THE SOUTHERN INTO THE CENTRAL PLAINS. THIS WILL BRING A PROLONGED HOT SPELL TO THE AREA...WITH SEVERAL DAYS IN A ROW OF HIGHS IN THE 90S. CANNOT RULE OUT AN ISOLATED STORM...ESPECIALLY AT NIGHT...AS WE WILL REMAIN ON THE NORTHERN PERIPHERY OF THE UPPER RIDGE WHERE WEAK UPPER LEVEL DISTURBANCES WILL PINWHEEL THROUGH OR CLOSE TO THE AREA. && .AVIATION... ONGOING SHOWERS AND THUNDERSTORMS ENTERING THE NRN PANHANDLE ATTM...WILL CONTINUE TO BE MONITORED FOR INCLUSION IN THE 12Z TAF ISSUANCE. THE LATEST NAM SOLN INDICATES POSSIBLE TSRAS IN WESTERN AND NORTH CENTRAL NEBRASKA LATER THIS MORNING. CONFIDENCE IS LOW IN THIS FORECAST THOUGH DUE TO LIMITED MID LEVEL FORCING PRESENT THIS MORNING. AGAIN...WILL NEED TO CLOSELY MONITOR RADAR TRENDS AND INCLUSION OF TSRAS WILL BE MADE AROUND FCST ISSUANCE. IN ADDITION TO TSRA CHANCES...SOME LOW CEILINGS AON 1500 FT AGL AND MVFR VISIBILITIES ARE POSSIBLE AT THE KLBF TERMINAL THROUGH 15Z THIS MORNING. SIMILAR TO MENTION OF THUNDERSTORMS...FCST CONFIDENCE REMAINS LOW...SO MENTION OF LOW VSBYS/CEILINGS WILL WAIT TILL NEAR FCST ISSUANCE. SKIES ARE EXPECTED TO CLEAR OFF LATER THIS AFTERNOON WITH SCATTERED CLOUDS AON 12000 FT AGL. CLOUD COVER MAY INCREASE THIS EVENING AS ANOTHER UPPER LEVEL DISTURBANCE LOCATED OVER THE SRN ROCKIES WILL DRIFT INTO SWRN NEBRASKA THIS EVENING. THUNDERSTORMS ARE POSSIBLE AND WILL BE HANDLED WITH A PROB30 GROUP AT KLBF...WHILE KVTN SHOULD BE WELL NORTH OF ANY CONVECTION. && .LBF WATCHES/WARNINGS/ADVISORIES...FLOOD WARNING CONTINUES UNTIL FURTHER NOTICE FOR LINCOLN COUNTY ALONG THE PLATTE RIVER...AS ELEVATED WATER LEVELS WILL CONTINUE DUE TO RELEASES FROM LAKE MCCONAUGHY. && DISCUSSION...TAYLOR AVIATION...BUTTLER
