Area forecast discussion, Aug 12, 1:22 PM CST, 38 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 222 PM CDT SUN AUG 12 2007 .SHORT TERM...LATEST WATER VAPOR IMAGERY FROM THIS AFTERNOON CONTINUES TO SHOW A BROAD UPPER RIDGE SITTING OVER THE SOUTHERN HALF OF THE CONUS. HOWEVER...ROUNDING THE TOP OF THIS RIDGE IS A POTENT NORTHERN STREAM WAVE SEEN STRETCHING FROM THE UPPER MIDWEST INTO THE CENTRAL HIGH PLAINS. RECENT OBJECTIVE SURFACE ANALYSIS SHOWS A NEARLY STATIONARY WARM FRONT RUNNING NEAR THE KANSAS...NEBRASKA BORDER. NORTH OF THIS FRONT DEEP BOUNDARY LAYER MOISTURE IS SEEN WITH DEWPOINTS IN THE LOWER TO MID 70S SEEN. QUICK CHECK OF RUC INITIALIZATION SHOWS CAPE VALUES IN EXCESS OF 4000 J/KG AND DEEP LAYER SHEAR OF 30 TO 40 KTS. SCATTERED ELEVATED CONVECTION IS ALREADY SEEN NORTH OF THIS BOUNDARY WITH STRONGER TO SEVERE CONVECTION SEEN IN AN MCS ACROSS NORTH CENTRAL NEBRASKA. THE UPPER RIDGE THEN BEGINS TO AMPLIFY NORTHWARD ACROSS THE CENTRAL PLAINS TONIGHT INTO MONDAY. THIS SHOULD HELP TO PUSH THE STALLED BOUNDARY NORTHWARD TONIGHT INTO EARLY MONDAY. GIVEN THE MOVEMENT OF THIS FRONT ALONG WITH THE AFOREMENTIONED UPPER WAVE...SCATTERED CONVECTION SHOULD CONTINUE TO A PROBLEM ALONG AND NORTH OF THE WARM FRONT ACROSS SOUTH CENTRAL NEBRASKA INTO THE EARLY EVENING. MAIN QUESTION IS WHETHER CONVECTION OVER NORTH CENTRAL NEBRASKA WILL BEGIN TO TURN SOUTHEAST AND BECOME THE MAIN SHOW OR IF SURFACE BASED CONVECTION CAN DEVELOP FURTHER SOUTH ALONG THE FRONT. AT THIS POINT IT LOOKS AS THOUGH THE ATMOSPHERE REMAINS FAIRLY CAPPED ALONG THE BOUNDARY WITH LITTLE CU DEVELOPMENT SEEN. BASED ON THIS SETUP...WILL GAMBLE TOWARD CONVECTION OVER NORTH CENTRAL NEBRASKA SLIDING SOUTHEAST THIS AFTERNOON TO EARLY EVENING WHILE MINIMAL CONVECTION DEVELOPS FURTHER SOUTH. AS ALREADY MENTIONED...PARAMETERS ARE SHOWING A DECENT SEVERE THREAT AND CAN SEE A FEW STORMS PRODUCING DAMAGING WINDS. THE BOUNDARY IS THEN SHOWN TO LIFT NORTH OF THE FORECAST AREA BY EARLY ON MONDAY WHILE THE UPPER RIDGE REMAINS IN CONTROL OF THE CENTRAL PLAINS. IT LOOKS AS THOUGH THIS WILL BRING ANOTHER HOT AND SUNNY DAY TO THE AREA WITH HIGHS IN THE UPPER 90S TO AROUND 100 EXPECTED. IT DOES LOOK AS THOUGH SEVERAL LOCATIONS WILL SEE HEAT INDEX READINGS AT OR ABOVE 105 DEGREES. THE MAIN QUESTION IS WHETHER LOW TEMPERATURES TONIGHT AND MONDAY NIGHT WILL STAY ABOVE 75 DEGREES PER HEAT ADVISORY CRITERIA. IT WILL BE CLOSE IN SEVERAL LOCATIONS...BUT IT LOOKS AT THIS POINT AS THOUGH THE LOW TEMPERATURES WILL DROP BELOW 75 AT LEAST ONE IF NOT BOTH NIGHTS. OVERNIGHT CREW CAN REEVALUATE CONDITIONS...BUT WILL OPT TO NOT ISSUE A HEAT ADVISORY FOR NOW. .LONG TERM...12Z TUESDAY THROUGH SUNDAY. MAIN CONCERN WILL BE CHANCE FOR THUNDERSTORMS TUESDAY NIGHT THROUGH WEDNESDAY NIGHT AND AGAIN SATURDAY...THEN TEMPERATURES THROUGH THE PERIOD. THE UPPER RIDGE CONTINUES INTO TUESDAY BUT IS PUSHED TO THE SOUTH A LITTLE AS A WEAK SHORT WAVE SLIDES THROUGH ON WEDNESDAY. AT THE SURFACE A FRONTAL BOUNDARY MOVES INTO THE FORECAST AREA ON TUESDAY AND LINGERS THROUGH EARLY THURSDAY. EXPECT THAT AS THE UPPER WAVE MOVES THROUGH THE AREA WILL BE THE BEST CHANCE FOR SHOWERS AND THUNDERSTORMS...OR TUESDAY NIGHT THROUGH WEDNESDAY NIGHT. THERE IS ANOTHER WEAK SHORT WAVE THAT MOVES ACROSS THE RIDGE AND A FRONTAL BOUNDARY THAT MOVES INTO THE FORECAST AREA ON SATURDAY. THERE IS A POSSIBILITY THAT THERE MIGHT BE SOME SHOWERS AND THUNDERSTORMS ON SATURDAY WITH THIS SYSTEM. TEMPERATURES SHOULD REMAIN ABOVE NORMAL THROUGH THE PERIOD. TUESDAY SHOULD BE THE WARMEST WITH TEMPERATURES AT 850MB ARE AT OR ABOVE 30 DEGREES C WITH SOUTH TO SOUTHWEST WINDS. THEN AFTER THE BOUNDARY MOVES THROUGH AND WITH MORE CLOUDS AND A CHANCE FOR RAIN THE TEMPERATURES SHOULD COOL OFF A FEW DEGREES. THE RELATIVELY COOLER TEMPERATURES SHOULD CONTINUE THROUGH THE REMAINDER OF THE PERIOD. && .AVIATION...MAIN CHALLENGE FOR THE 18Z KGRI TAF IS TIMING OF THUNDERSTORMS THIS AFTERNOON AND EVENING. A WEAK FRONTAL BOUNDARY ACROSS NORTHERN KANSAS WILL BEGIN TO LIFT NORTH THROUGH THE AREA THIS AFTERNOON AND TONIGHT. THIS HAS ALREADY RESULTED IN SCATTERED THUNDERSTORMS DEVELOPING NEAR THE GRAND ISLAND TERMINAL THIS PAST MORNING TO EARLY AFTERNOON. APPEARS THE TERMINAL SHOULD BE ENTERING A BRIEF QUIET PERIOD THROUGH 20Z AS THE STORMS REMAIN FAR ENOUGH SOUTH AND WEST TO NOT IMPACT THE TERMINAL. HOWEVER...AFTER 20Z IT APPEARS CONVECTION FURTHER WEST WILL IMPACT KGRI. THIS CONVECTION SHOULD BE EAST OF THE TERMINAL BY EARLY TO MID EVENING WITH MAINLY SOME HIGH CLOUD COVER LEFT OVER THROUGH THE NIGHT. && .GID WATCHES/WARNINGS/ADVISORIES... NE...NONE. KS...NONE. &&
