   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS NORTH AND SOUTH DAKOTA
   AND NWRN MN...
   
   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE DELMARVA REGION AND
   EXTREME SRN NJ...
   
   ...NORTH AND SOUTH DAKOTA AND NWRN MN...
   STRONG HEIGHT FALLS OF 60-90M PER 12 HOURS WILL CONTINUE TO SPREAD
   EAST OVER THE NRN PLAINS TONIGHT AND RESULT IN A DEEPENING SURFACE
   LOW WHICH WILL TRACK NEWD FROM WRN ND INTO NWRN MN THROUGH DAYBREAK.
   SO FAR ACROSS THE REGION...CONVECTIVE INTENSITY APPEARS TO HAVE BEEN
   SOMEWHAT OFFSET BY RELATIVELY WARM MID LEVEL TEMPERATURES DESPITE
   VERY FAVORABLE LOW LEVEL FORCING FOR ASCENT NEAR SURFACE LOW AND
   DRYLINE. THIS SITUATION MAY BEGIN TO CHANGE OVER THE NEXT FEW HOURS
   AS LARGE SCALE FORCING FOR ASCENT...AND DECREASING STATIC STABILITY
   ASSOCIATED WITH THE SHORT WAVE IMPULSE...SPREAD NEWD FROM ERN WY/MT.
   TSTMS SHOULD CONTINUE AND POSSIBLY INCREASE IN STRENGTH AND COVERAGE
   LATER TONIGHT AS CONVECTIVE INHIBITION CONTINUES TO WEAKEN WITH
   STEEPENING LAPSE RATES AND LOW LEVEL JET ACTS TO ENHANCE MASS
   CONVERGENCE FROM CNTRL/ERN SD NNEWD ACROSS ND. CLOUD BEARING SHEAR
   IS FORECAST TO INCREASE AS WIND MAX MOVES EWD. STORMS WITHIN
   EXPANDING WARM SECTOR WILL BE RELATIVELY HIGH BASED AND POSE A
   WIND/HAIL THREAT...WHILE ACTIVITY ALONG/NORTH OF THE WARM FRONT WILL
   REMAIN ELEVATED WITH PRIMARY SEVERE WEATHER THREAT BEING LARGE HAIL.
   
   
   ...DELMARVA REGION AND EXTREME SRN NJ...
   STRONG/SEVERE PREFRONTAL SQUALL LINE CONTINUES TO MOVE ESEWD FROM
   DELAWARE BAY SWWD TO NEAR LYH. WITH 30-40KT OF MID LEVEL FLOW
   ORIENTED NEARLY PERPENDICULAR TO THE LINE...AND A VERY UNSTABLE
   AIRMASS REMAINING TO THE EAST OF THE STRONG OUTFLOW...EXPECT SEVERE
   WIND THREAT AND ISOLD HAIL TO CONTINUE TO BE A PROBLEM FOR ANOTHER
   COUPLE OF HOURS BEFORE CONVECTIVE INTENSITY BEGINS TO WANE.
