STORMS MOVING THROUGH THE AREA.

IN THE SHORT TERM...EXPECT LINE OF STORMS PUSHING INTO THE NORTHERN
CWA THIS MORNING ALONG EASTWARD MOVING COLD FRONT SHOULD BE LIMITED
TO PORTIONS OF THE NORTHERN CWA AND EVENTUALLY DIE OFF SHORTLY AFTER
SUNRISE WHEN LLVL JET WEAKENS. ALOT OF JUICE TO WORK WITH IN THE

AXIS CUTTING THROUGH THE CWA. HIGH DEGREE OF INSTABILITY WITH AMPLE
MOISTURE WITH SBCAPES AROUND 4500J/KG AND LI ABOUT -8.

NEXT CHANCE FOR THUNDER COMES TONIGHT AS MODELS STILL SHOW DECENT
ASSENT ACROSS THE AREA. BETTER CHANCES APPEAR TO COME AFTER
MIDNIGHT WHEN AREA OF QPF DEVELOPS IN CNTRL NEB IN RESPONSE TO
BOUNDARY LAYER FORCING. PCPN SHOULD SPREAD IN FROM THE WEST.
BOUNDARY STILL PROGGED OVER THE CWA THROUGH THE EXTENDED PERIODS
WITH UPPER LEVEL IMPULSES ROLLING THROUGH. THIS WARRANTS MAINTAINING
POPS THROUGH AT LEAST MONDAY. PATTERN FINALLY EVOLVES TUESDAY
TO VERY WEAK UPPER LEVEL RIDGING ACROSS THE PLAINS. WILL THEREFORE
GO DRY TUESDAY.

THUNDERSTORM CHANCES WILL CONTINUE LATE THIS AFTERNOON AND THROUGH

BORDER. AS THE EVENING PROGRESSES...STORMS WILL BACKBUILD INTO
SOUTHEAST NEBRASKA AND SOUTHWEST IOWA AS THE FRONTAL BOUNDARY LIFTS
BACK NORTH. AMPLE MOISTURE AND INSTABILITY SUGGEST THUNDERSTORM
ACTIVITY SHOULD BE ABLE TO LAST THROUGH THE MAJORITY OF THE
OVERNIGHT HOURS.

.DAYS TWO THROUGH SEVEN...WEDNESDAY NIGHT THROUGH TUESDAY

THUNDERSTORM CHANCES REMAIN IN THE FORECAST EACH DAY FROM WEDNESDAY
NIGHT THROUGH MONDAY.  THE STORMS WILL BE MOST LIKELY DURING THE LATE
AFTERNOON THROUGH OVERNIGHT HOURS. THE POTENTIAL FOR SEVERE WEATHER
WILL REMAIN POSSIBLE THROUGH THE ENTIRE PERIOD.

.SPOTTER INFORMATION STATEMENT...

TONIGHT MAINLY OVER SOUTHEAST NEBRASKA AND SOUTHWEST IOWA.
