Area forecast discussion, Aug 2, 4:10 PM CDT, 5 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 410 PM CDT SUN AUG 2 2015 .SHORT TERM...(THIS EVENING THROUGH MONDAY) ISSUED AT 340 PM CDT SUN AUG 2 2015 SATELLITE AND OBSERVATIONS SHOW A MOSTLY CLEAR SKY ACROSS THE FORECAST AREA. THE EXCEPTION IS ONE LITTLE PATCH OF CLOUDS IN THE FAR NORTHWEST PART OF THE AREA. THE LATEST RADAR INDICATES THERE IS A CLUSTER OF THUNDERSTORMS THAT HAS DEVELOPED. SURFACE ANALYSIS SHOWS A COLD FRONT THROUGH NORTHERN NEBRASKA AT THIS TIME. THIS COLD FRONT IS EXPECTED TO CONTINUE TO MOVE TO THE SOUTH DURING THE REMAINDER OF THE AFTERNOON AND TONIGHT. THE LOCATION OF THE FRONT WILL BE THE FOCUS FOR ANY THUNDERSTORMS THAT DEVELOP THIS AFTERNOON AND EVENING. WITH THE FRONT STILL TO THE NORTH OF THE FORECAST AREA...THE NORTHERN PART OF THE FORECAST AREA HAS THE BEST CHANCE FOR THUNDERSTORMS DURING THE REMAINDER OF THE AFTERNOON. AS THE FRONT SLIDES TO THE SOUTH THIS EVENING THE CHANCES FOR THUNDERSTORMS WILL ALSO MOVE TO THE SOUTH. EXPECT THUNDERSTORMS TO BE MAINLY DIURNALLY DRIVEN AND AS THE SUN GOES DOWN THIS EVENING THE THUNDERSTORMS SHOULD DIMINISH. AN UPPER LEVEL WAVE WILL MOVE INTO THE AREA LATER TONIGHT. THIS IS A WEAK WAVE THAT IS FURTHER NORTH. MODELS HAVE A FEW DIFFERENCES IN THE LOCATION OF THE PRECIPITATION. MOST OF THEM KEEP IT NORTH OF THE AREA THROUGH TONIGHT THEN IT SLIDES A LITTLE TO THE SOUTH DURING THE MORNING HOURS AND INTO THE AFTERNOON. .LONG TERM...(MONDAY NIGHT THROUGH SUNDAY) ISSUED AT 340 PM CDT SUN AUG 2 2015 OUR BETTER CHANCES FOR THUNDERSTORMS WILL BE TUESDAY INTO TUESDAY NIGHT IN ASSOCIATION WITH AN UPPER LEVEL SHORT WAVE TROUGH THAT WILL SLIDE AROUND THE PERIPHERY OF THE LARGER WESTERN CONUS UPPER RIDGE. TUESDAY INTO TUESDAY NIGHT...THE UPPER TROUGH WILL MOVE EAST ACROSS THE FORECAST AREA PROVIDING SOME DYNAMIC SUPPORT FOR THUNDERSTORMS. THERE WILL BE FAIRLY DECENT INSTABILITY AROUND BY AFTERNOON...BUT THE DEEP LAYER SHEAR WILL BE VERY WEAK AT AROUND 10 KTS SO THUNDERSTORMS WILL QUICKLY PULSE UP AND DOWN. THEREFORE...SEVERE POTENTIAL WILL BE RATHER LIMITED AND PRIMARILY A THREAT OF SEVERE WINDS FROM COLLAPSING STORM CELLS. TEMPERATURES WILL BE COOLER WITH THE CLOUDS...ONLY EXPECTING HIGHS IN THE LOW 80S FOR MOST LOCATIONS. WEDNESDAY...THE UPPER TROUGH WILL BEGIN TO TRACK EAST OF OUR FORECAST AREA. EASTERN ZONES WILL SEE A SLIGHTLY BETTER CHANCE AT THUNDERSTORMS BUT THE BEST CHANCES FOR THUNDERSTORMS WILL SHIFT EAST OF OUR FORECAST AREA AS WE HEAD THROUGH THE DAY. THURSDAY THROUGH SUNDAY...WE COULD SEE ANOTHER SHORT WAVE TROUGH MOVE THROUGH ON THURSDAY AND THEN ANOTHER ONE BY LATE SATURDAY OR SUNDAY. THEREFORE...OUR BETTER CHANCES FOR THUNDERSTORMS IN THIS OUTER PERIOD APPEAR TO BE THURSDAY EVENING/THURSDAY NIGHT AND AGAIN SATURDAY EVENING/SATURDAY NIGHT. HOWEVER...THE TIMING AND PLACEMENT OF THESE SHORTWAVES IS STILL A BIT UNCERTAIN WITHIN THE FORECAST MODELS AND THUS CONFIDENCE IS STILL RATHER LOW. THEREFORE...WILL KEEP ALL RAIN CHANCES IN THE OUTER PERIODS LESS THAN 50/50 FOR NOW WITH THE HIGHER CHANCE DAYS BEING WHEN THOSE UPPER TROUGHS MOVE THROUGH. OVERALL TEMPERATURES SHOULD BE AROUND NORMAL TO A FEW DEGREES BELOW NORMAL. && .AVIATION...(FOR THE 18Z KGRI/KEAR TAFS THROUGH 18Z MONDAY AFTERNOON) ISSUED AT 1221 PM CDT SUN AUG 2 2015 CURRENTLY THERE ARE CLEAR SKIES ACROSS THE AREA. THERE IS A WEAK COLD FRONT THAT WILL MOVE THROUGH THE TERMINAL AREAS DURING THE AFTERNOON HOURS. WINDS WILL BE LIGHT AND VARIABLE AS THE FRONT MOVES THROUGH THEN TURN TO THE NORTH OR NORTHEAST. THERE COULD BE A FEW THUNDERSTORMS AROUND AS THE FRONT MOVES THROUGH. && .GID WATCHES/WARNINGS/ADVISORIES... NE...NONE. KS...NONE. && SHORT TERM...JCB LONG TERM...WESELY AVIATION...JCB
