   VALID 031845Z - 032015Z
   
   A SEVERE THREAT MAY DEVELOP ACROSS THE REGION THIS AFTERNOON.
   ISOLATED WIND DAMAGE AND HAIL WILL BE POSSIBLE WITH THE STRONGER
   CELLS OVER THE NEXT FEW HOURS. THE THREAT SHOULD REMAIN TOO MARGINAL
   FOR A WW.
   
   18Z SFC ANALYSIS SHOWS THE CENTER OF A SFC LOW NEAR CHICAGO IL WITH
   A SFC TROUGH EXTENDING SEWD ACROSS IND INTO NRN KY. DEWPOINTS ALONG
   THIS TROUGH ARE IN THE MID 60S F AND OBJECTIVE ANALYSIS INDICATES
   POCKETS OF MODERATE INSTABILITY ARE DEVELOPING NEAR LOUISVILLE KY
   AND TOLEDO OH. ALTHOUGH VERTICAL SHEAR ON REGIONAL WSR-88D VWPS IS
   RELATIVELY WEAK ACROSS MUCH OF THE OH VALLEY...ENOUGH INSTABILITY
   MAY DEVELOP FOR AN ISOLATED SEVERE THREAT. IN ADDITION...A LOW-LEVEL
   JET AND 0-3 KM LAPSE RATES ARE INCREASING ACROSS ERN IND AND WRN OH
   ACCORDING TO THE LATEST RUC ANALYSIS. THIS SUGGESTS AN ISOLATED WIND
   DAMAGE POTENTIAL MAY EXIST WITH THE STRONGER CELLS THIS AFTERNOON.
   DUE TO RELATIVELY WEAK VERTICAL SHEAR...THE THREAT SHOULD REMAIN
   MARGINAL
