&&

.DISCUSSION...
KEY MESSAGE 1)

Northeast flow coming off of Lake Erie led to the development of
dense fog overnight across parts of west central Ohio and some areas
in central Ohio. The fog continues to improve and shift east of the
region. Therefore, the dense fog advisory has been allowed to expire.


KEY MESSAGE 2)
Mid level ridge extending from the western Gulf to the western Great
Lakes will shift slightly eastward into the early part of the week.
Surface high situated east of the area will remain through the
weekend. Then a weak front will sag south across the area Monday into
Monday night.

The mid level ridge gets slowly suppressed, finally breaking down by
mid week as a short wave lifts out of the southern Plains and up the
Ohio Valley. The front will wash out as another high moves from
Ontario to the northeast Atlantic coast.

All put together, the extended period of dry conditions will persist
well into next week, perhaps the entirety of the week. Temperatures
will be above normal.

.AVIATION /13Z SATURDAY THROUGH WEDNESDAY/...
