A MULTITUDE OF ISSUES SURROUNDING THIS FORECAST AS ACTIVE LATE AUTUMN PATTERN DEVELOPS ACRS THE CENTRAL UNITED STATES. CURRENTLY...SFC LOW PASSING THRU SE SOUTH DAKOTAS WITH DRY LINE PUNCHING INTO WESTERN IA. INSTABILITY HAVING A HARD TIME INCREASING WITH LOW LEVEL CLDS INHIBITING HEATING...HOWEVER MOST RECENTLY SOME SUNSHINE HAS POKED THROUGH ACRS THE WESTERN THIRD OF THE STATE...SO THINGS MAY HEAT A BIT MORE. WNDS STILL APPEAR TO REMAIN PRIMARY THREAT BUT ENOUGH ENHANCED SHEAR AND INSTABILITY JUST ALONG DRY LINE AXIS MAY PROVIDE THE NECESSARY INGREDIENTS FOR A BRIEF TORNADO OR TWO. OTHERWISE...DRY LINE/BOUNDARY WL PASS THROUGH THIS EVENING WITH TIGHTENING PRESSURE GRADIENT AND STRONG SUBSIDENCE. 45-55KTS WL BE COMMON JUST OFF THE SFC FM THE WNW AND MOMENTUM TRANSPORT TO THE SFC WL HELP TO SUSTAIN WINDS OVERNIGHT INTO SUNDAY.
