.SHORT TERM...THE BEST CONVECTION IS OVER THE PALMER RIDGE AREA AT
THIS TIME.  THERE IS A PRETTY DECENT BOUNDARY PUSHING NORTHWARD FROM
THE CONVECTION.  THERE IS ALSO A BOUNDARY OVER WASHINGTON COUNTY

AROUND 50 F OVER MOST OF THE PLAINS.  MODELS SHOW DECENT BOUNDARY
LAYER DEW POINTS OVER ALL THE PLAINS OVERNIGHT.  ACARS SOUNDINGS

BOUNDARY LAYER OVER US.  THE THETA-E AXIS REMAINS OVER THE EASTERN
PLAINS.  SOUNDINGS HAVE HEALTHY CAPES OVER US.  THE ONLY REAL
