Area forecast discussion, Jun 8, 2:32 PM CST, 9 hours 29 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 332 PM CDT WED JUN 8 2011 .SHORT TERM...TONIGHT MAIN CONCERN WILL FOCUS AROUND NEARLY STALLED OUT BOUNDARY ACROSS OUR FAR SOUTHEAST. SFC CDFNT CONTINUES TO SLOWLY PUSH SOUTHEAST AND EXTENDS ACROSS OUR FAR SOUTHEASTERN COUNTIES THIS AFTERNOON. DESPITE STRONG INSTABILITY AHEAD OF THE BOUNDARY...THE AREA REMAINS CAPPED. SCATTERED CU DECK HAS BECOME MORE WIDESPREAD AND CONVECTION COULD FIRE UP EARLY THIS EVENING AS WEAK APPROACHING SHORTWAVE ENERGY HELPS INCREASE MID LEVEL LAPSE RATES. EXPECT MUCH OF THE ACTIVITY TO REMAIN JUST OUT OF OUR CWA HOWEVER A FEW STORMS COULD GET GOING IN OUR EXTREME SOUTHEASTERN COUNTIES. LLVL CONVERGENCE SHOULD SUSTAIN CONVECTION OVERNIGHT ALONG THE BOUNDARY. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE POSSIBLE NORTH OF THE FRONT ACROSS MUCH OF THE FORECAST AREA OVERNIGHT AS THE BOUNDARY STALLS. LIMITING FACTOR WILL BE DRIER AIR TO OUR NORTHWEST WHICH CONTINUES TO SINK SEWD. KERN .LONG TERM...TOMORROW THROUGH WEDNESDAY MAIN FORECAST CONCERNS ARE RAIN AND THUNDERSTORM CHANCES TOMORROW THROUGH TOMORROW NIGHT...THEN AGAIN FROM LATE WEEKEND INTO EARLY NEXT WEEK...AS MORE ACTIVE PATTERN CONTINUES. UPPER-LEVEL TROUGH OVER THE ROCKIES AND RIDGE OVER THE SOUTHEAST WILL LEAD TO SOUTHWESTERLY FLOW ACROSS THE CENTRAL US. INITIAL WAVE EJECTS FROM WY THORUGH THE DAKOTAS/NORTHERN GREAT LAKES FROM FRIDAY THROUGH SATURDAY...WITH MAIN SHORTWAVE ENERGY MOVING ACROSS SD/NEB THROUGH FRIDAY. 850MB BOUNDARY IS PROGGED TO HANG UP IN EASTERN NEB/SOUTHERN TO CENTRAL IA THROUGH THURSDAY NIGHT...PROVIDING FOCUS FOR AT LEAST ELEVATED NOCTURNAL CONVECTION TOMORROW NIGHT...ESPECIALLY AS 850MB LOW TRAVELS ALONG THE FRONT ACROSS EASTERN NEB/WESTERN IA THURSDAY EVENING. DO HAVE A POTENTIAL FOR SURFACE-BASED CONVECTION TOMORROW AFTERNOON/EVENING IN THE FAR SOUTHERN/SOUTHEASTERNMOST CWA AS SURFACE-BASED INSTABILITY BUILDS JUST SOUTH OF THE LINGERING BOUNDARY. 0-6KM BULK SHEAR TOMORROW IS PROGGED AT 40-50KT...MORE THAN ENOUGH FOR SUPERCELLS WITH ATTENDANT SEVERE WEATHER HAZARDS. SHOWERS/THUNDERSTORMS SHOULD EXPAND THROUGH THE EVENING ALONG THE ELEVATED WARM FRONT ACROSS EASTERN NEB/IA AS LOW-LEVEL JET INCREASES AND EJECTING UPPER-LEVEL WAVE APPROACHES. EXPECT AN AREA OF FAIRLY HEAVY RAINFALL SOMEWHERE ALONG AND EAST OF THE MISSOURI RIVER...BUT CONFIDENCE IS LOW ON PINPOINTING THE HEAVIEST RAINFALL AT THIS POINT. ELEVATED HAILERS COULD ALSO BE A THREAT. ACTIVITY WILL MOVE OUT OF THE CWA THROUGH THE EARLY MORNING HOURS ON FRIDAY...WITH SOMEWHAT DRIER WEATHER BEHIND IT. MODELS INDICATE STORMS INITATING ONCE AGAIN ON FRIDAY AFTERNOON/EVENING ALONG THE LINGERING BOUNDARY...BUT IT DOES APPEAR THAT THE BOUNDARY WILL PUSH FAR ENOUGH SOUTHWARD INTO MO/KS THAT STORMS WILL STAY OUT OF THE CWA...AND HAVE KEPT THE FCST DRY FOR FRIDAY AFTERNOON THROUGH SATURDAY. HIGH PRESSURE MOVES ACROSS THE CWA ON FRIDAY NIGHT...WITH THE COOLEST TEMPS IN THE PERIOD POSSIBLE. RETURN FLOW INTO CENTRAL/WESTERN NEB DEVELOPS ON SATURDAY AROUND THE PERIPHERY OF THE HIGH...WITH CONTINUED WEST-SOUTHWESTERLY UPPER-LEVEL FLOW ACROSS THE CENTRAL US. CONVECTION...ESPECIALLY NOCTURNAL...MAY RETURN TO THE AREA AS EARLY AS SATURDAY NIGHT...WITH ANOTHER PERSISTENT 850MB BOUNDARY DEVELOPING BY MONDAY EVENING. PERIOD FROM SATURDAY NIGHT THROUGH TUESDAY NIGHT COULD BE ACTIVE AS NEXT UPPER-LEVEL TROUGH EJECTS ACROSS THE CENTRAL US...NOT NECESSARILY AS A PERSISTENT WASH-OUT BUT WITH INTERMITTENT PERIODS OF SHOWERS AND THUNDERSTORMS DURING THAT TIME. UPPER-LEVEL PATTERN TRANSITIONS TO NORTHWESTERLY FLOW IN WAKE OF THE EARLY WEEK EJECTING TROUGH. PATTERN OVERALL WOULD FAVOR LIGHTER AND MORE INTERMITTENT PRECIP...IF ANY...AND HAVE KEPT FORECAST DRY WEDNESDAY AND BEYOND. THAT SAID...SHORWAVES RIPPLING THROUGH THE NORTHWESTERLY FLOW COULD TOUCH OFF TRANSIENT SHOWER/THUNDERSTORM ACTIVITY...WHICH WILL BE BETTER RESOLVED MUCH CLOSER TO THE PATTERN TRANSITION. KEPT TEMPS NEAR GUIDANCE...WHICH IS NEAR OR JUST ABOVE CLIMO. MAYES && .AVIATION... TAF SITES KOFK/KOMA/KLNK 18Z TAFS SFC FRONT HAS PUSHED SOUTH ACROSS ALL THREE TAF SITES. VFR CONDITIONS ARE EXPECTED THRU MUCH OF THE PERIOD WITH SOME SHOWERS POSSIBLY DEVELOPING ACROSS KOMA AND KLNK AFTER 06Z TONIGHT AS THE SFC BOUNDARY STALLS TO OUR SOUTH. HAVE INCLUDED A PROB30 GROUP FOR THIS ACTIVITY. MVFR CIGS ARE EXPECTED LATER TONIGHT AS AN EXTENSIVE STRATUS DECK OVER SOUTH DAKOTA CONTINUES TO PUSH SOUTH.
