320 PM MDT THU JUN 16 2005

.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
WITH CUMULUS CLOUDS JUST BEGINNING TO DEVELOP.  DEW POINTS ARE STILL
AROUND 50 F OVER MOST OF THE PLAINS.  MODELS SHOW DECENT BOUNDARY
LAYER DEW POINTS OVER ALL THE PLAINS OVERNIGHT.  ACARS SOUNDINGS
STILL SHOW CAPE VALUES OVER 1000 JOULES/KG.  THE THETA-E AXIS STAYS

LEVEL PRESSURE AND WIND FIELDS KEEP SOUTHEASTERLY FLOW IN THE
BOUNDARY LAYER OVER US.  THE THETA-E AXIS REMAINS OVER THE EASTERN
PLAINS.  SOUNDINGS HAVE HEALTHY CAPES OVER US.  THE ONLY REAL
PROBLEM IS THE MID LEVEL WARMING WITH THE RIDGE.  THE CROSS SECTIONS
