EARLY THIS EVENING A DRYLINE EXTENDS FROM A SURFACE LOW IN WRN KS
SWD THROUGH CNTRL OK...N CNTRL AND CNTRL TX. A WARM FRONT EXTENDS
FROM SRN IL WWD INTO CNTRL MO THEN SWWD INTO NRN OK WHERE IT
INTERSECTS THE DRYLINE. NUMEROUS MESOSCALE BOUNDARIES EXIST IN WARM
SECTOR WHERE THE ATMOSPHERE REMAINS MARGINALLY TO MODERATELY
UNSTABLE WITH MLCAPE FROM 500-1200 J/KG FROM ERN OK INTO THE LOWER
MS VALLEY. WV IMAGERY AND RUC OBJECTIVE ANALYSIS SHOW A STRONG VORT
MAX OVER CNTRL KS AND OK WITH ATTENDANT MID LEVEL JET ACROSS SRN OK

UPPER MS VALLEY WITH THE LOW LEVEL JET STRENGTHENING TO 65+ KT AS IT

EXPECTED OVER PARTS OF THE LOWER TO MID MS VALLEY REGIONS WHERE
ASCENT ATTENDING NEWD EJECTING VORT MAX AS WELL AS LARGE LOW LEVEL
HODOGRAPHS AND DEEP LAYER SHEAR WILL EXIST. THREAT FARTHER NWD INTO
CNTRL AND NRN IL IS MORE CONDITIONAL DUE TO MARGINAL INSTABILITY IN
THIS REGION.
