   ...SRN AND CNTRL PLAINS...
   ANALYSIS SHOWED A WARM FRONT EXTENDING ACROSS NRN KS WITH A DRYLINE
   EXTENDING S FROM COLBY KS TO CHILDRESS TX. SFC THERMAL RIDGE
   EXTENDED NWD FROM NW OK INTO CNTRL KS WITH CELLS INCREASING ACROSS
   NWRN-CNTRL KS BEHIND CLEARING LINE. TOWERING CU IS ALSO DEVELOPING
   IN THE VICINITY OF THE DRYLINE ACROSS WCNTRL OK. THESE TWO AREAS
   APPEAR TO BE THE MOST LIKELY PLACES FOR INTENSE THUNDERSTORM
   DEVELOPMENT IN THE NEXT FEW HOURS WITH AREAS FARTHER S POSSIBLY
   HOLDING OFF LONGER...SEE MCD 850/851/852. STRONG LARGE-SCALE
   FORCING...IMPRESSIVE DEEP LAYER SHEAR OF 60 TO 70 KT AND STRONG
   DIRECTIONAL SHEAR WITH HEIGHT WILL FAVOR DISCRETE SUPERCELLS. AS
   THE SUPERCELLS MOVE N AND EWD INTO THE MOIST AXIS...TORNADOES/LARGE
   HAIL AND DAMAGING WINDS WILL BECOME LIKELY ACROSS A WIDESPREAD
   AREA. THE GREATEST THREAT FOR LONG-TRACK STRONG TO VIOLENT
   TORNADOES APPEARS TO BE ACROSS CNTRL AND NRN KS WERE CLOUD HEIGHTS
   WILL BE LOWER WITH LCL HEIGHTS OF 600 TO 800 METERS. THIS AREA HAS
   CLOSER PROXIMITY TO THE LOW-LEVEL JET AND WAS E OF AN APPROACHING
   MID-LEVEL VORT MAX. SFC WINDS ARE ALSO BACKED E AND N OF THE SFC
   LOW WHICH HAVE INCREASED LOW-LEVEL HELICITIES TO OVER 300 M2/S2.
   SUPERCELLS FURTHER S ALONG THE DRYLINE IN OK WILL ALSO HAVE THE
   POTENTIAL FOR STRONG TORNADOES WITH LARGE HAIL/DAMAGING WINDS
   LIKELY.  IF THE CAP CAN BREAK INTO CENTRAL TX...ISOLATED SUPERCELLS
   SHOULD DEVELOP WITH VERY UNSTABLE AIR AND 0-6 KM SHEAR AROUND 50
   KT. ISOLATED TORNADOES...LARGE HAIL AND DAMAGING WINDS WILL BE
   POSSIBLE.
   
   AS THE NEGATIVELY TILTED TROUGH SHIFTS NEWD AFTER MIDNIGHT...
   STRONG LARGE-SCALE FORCING AND THE INCREASING LOW-LEVEL JET WILL
   KEEP SUPERCELLS/BOW ECHOES GOING WITH A BROKEN LINE MOVING ACROSS
   ERN NE/ERN KS/ERN OK. TORNADOES AND LARGE HAIL/DAMAGING WINDS
   APPEAR LIKELY. BY LATE IN THE PERIOD...CURRENT THINKING IS THAT
   CONVECTION WILL BECOME MORE LINEAR ACROSS IA/MO WITH A TRANSITION
   TO SQUALL-LINE WITH EMBEDDED BOW ECHOES. WIND DAMAGE SHOULD BE THE
   PRIMARY THREAT LATE IN THE PERIOD.
   
   ...UPPER MS VALLEY/OH AND TN VALLEYS...
   ANALYSIS SHOWED A WARM FRONT LIFTING NWD ACROSS MO/NRN TN/SRN KY.
   MODERATE INSTABILITY WITH MLCAPE AROUND 1500 J/KG IS DEVELOPING
   ALONG AND S OF THE WARM FRONT. AS STORMS DEVELOP ALONG THE
   BOUNDARY...A FEW SUPERCELLS WILL BE POSSIBLE WITH 0-6 KM SHEAR
   VALUES AROUND 50 KT. LARGE HAIL AND DAMAGING WINDS WILL BE THE
   PRIMARY THREAT.
    
   ...MID ATLANTIC...
   ISOLATED SUPERCELLS AND SMALL LINES OF STORMS WILL CONTINUE MOVING
   SEWD ACROSS NRN VA INTO THE CENTRAL/SERN VA COAST INTO THE EVENING.
   AIR MASS REMAINS MODERATELY UNSTABLE...AND SUFFICIENT SHEAR WILL
   SUPPORT A THREAT OF LARGE HAIL AND DAMAGING WINDS.
