   ...SYNOPSIS...
   FURTHER AMPLIFICATION OF WRN RIDGE/ERN TROUGH PATTERN EXPECTED THIS
   PERIOD AS RIDGE BUILDS FARTHER N INTO CANADA AND VORT MAX NOW OVER
   MO CONTINUES SSE INTO THE LWR TN VLY. AT LWR LVLS...A BROAD
   ANTICYCLONE WILL EXPAND SLOWLY S/SW FROM THE CANADIAN PRAIRIES INTO
   MUCH OF THE CNTRL U.S. AS A WEAK FRONT PERSISTS ALONG THE E SLOPES
   OF THE APPALACHIANS. UPSLOPE FLOW ON THE SW FRINGE OF THE
