HVL PROFILER HAS SHOWN A STEADY INCREASE IN THE 1-2KM SSW FLOW
REGIME EARLY THIS EVE S OF AN H85-H7 BAROCLINIC ZONE STRADDLING THE
NEB/KS BORDER.  SSW LLJ WILL BE MAINTAINED AS MID/UPR JET CORE
INTENSIFIES OVER THE MO VLY/CORN BELT TONIGHT DOWNSTREAM FROM AN
APCHG TROUGH.  THIS WILL MAXIMIZE LOW/MID-LVL THETA-E ADVECTION IN A
BROAD ZONE SHIFTING FROM NE CO INTO S NEB AND N KS WITH TIME
TONIGHT.
THOUGH THE MOISTURE PROFILES WERE NOT OUTSTANDING PER REGIONAL 00Z
RAOBS...DNR/DDC LAPSE RATE PROFILE WAS QUITE STEEP AND GIVEN GRADUAL
MOISTENING OF THE PROFILE VIA ASCENT/COOLING...BANDS OF STRONG TSTMS
WILL BE LIKELY.  ROUGHLY 40-45 KTS OF EFFECTIVE SHEAR WILL BE
FAVORABLE FOR ISOLD-WDLY SCTD ROTATING UPDRAFTS GIVING LARGE HAIL.
ACTIVITY DVLPG OVER NE CO IS PROBABLY BEING AIDED BY ELY LOW-LVL
UPSLOPE FLOW AND COULD BE THE START OF THE WELL-ADVERTISED NOCTURNAL
EVENT.  EXPECT ADDITIONAL STORMS WILL DEVELOP FARTHER E WITH TIME
THIS EVE.  AS SUCH...A SEVERE TSTM WATCH MAY NEED TO BE CONSIDERED
FOR PARTS OF THE REGION.
