COMPLICATED WEATHER.  SYNOPTIC FEATURES ACROSS THE AREA INCLUDE A
WARM FRONT EXTENDING ACROSS NORTHEAST OHIO...WITH DEWPOINTS STILL IN
THE 30S NORTH OF THIS FRONT AND IN THE MID 50S SOUTH.  THEN THE
REMNANTS OF A COLD FRONT CUT THROUGH WESTERN OH SOUTH TO THE MID
MISSISSIPPI VALLEY.  A BROAD AREA OF LOW PRESSURE ENCOMPASSES THE
WHOLE REGION WITH A NEARLY STATIONARY CLOSED UPPER LOW ACROSS WI/MN
AND A FEW SHORTWAVES MOVING ACROSS THE LOWER MISS R. AND TN R.
VALLEYS TO THE OHIO VALLEY.

WHAT IS EXPECTED IS WITH THE HEATING OF THE DAY AND THE ADDITIONAL

UPPER LOW FROM THE MIDWEST NEARS...THIS FRONTAL SYSTEM WILL PUSH OFF
