   ...SYNOPSIS...
   A DRY AIR MASS IN THE WAKE OF A POLAR FRONT WILL ENCOMPASS MOST OF

   PLAINS. THE COLD FRONT IS FORECAST TO BECOME POSITIONED ACROSS THE
   ERN GULF COAST INTO THE SERN ATLANTIC. WEAK FRONTAL CONVERGENCE AND
   VERY MARGINAL INSTABILITY WILL HINDER CONVECTIVE
   POTENTIAL...ALTHOUGH A FEW SHOWERS WILL STILL BE POSSIBLE. ACROSS
   THE SOUTHWEST...A LARGE CLOSED LOW WILL SLOWLY MIGRATE EWD INTO AZ
   BY THE END OF THE PERIOD...WITH SOME THUNDERSTORMS POSSIBLE IN
   ASSOCIATION WITH COLDER MIDLEVEL TEMPERATURES. LAKE EFFECT BANDS MAY
   DEVELOP WITHIN A WLY AND NWLY DEEP-LAYER FLOW REGIME ACROSS PORTIONS
   OF THE GREAT LAKES...WITH SOME EMBEDDED LIGHTNING STRIKES POSSIBLE.
