Updated aviation portion for 18Z TAF issuance

.SHORT TERM...Today...Tonight...and Wednesday
Issued at 222 AM CDT Tue May 17 2016

Showers with a surface cold front and then followed with the 850
fgen region continues to push south of the area early this
morning. Satellite imagery shows departing mid level clouds with
this system over parts of East Central Wisconsin. Also early this
morning mid level clouds were noted over the northern Great Lakes
region into Northern Minnesota in the upper short wave trough
axis dropping south over the area today. In addition, cool 850
temps around 0 C for much of the today will combine with the upper
trough for period of diurnal cu. Surface dewpoints in the
northeast flow were dropping into the 20s behind the front so
a high base cu anticipated.

Potential of another frost headline tonight over at least North
Central Wisconsin with surface temps falling to around 30. Will
let the day crew hoist any additional headlines later today due to
an ongoing headline in effect this morning.

With plenty of sunshine, temperatures will modify back closer to
normal by mid week as the cool high pressure system gradually
shifts eastward.

.LONG TERM...Wednesday Night Through Monday
Issued at 222 AM CDT Tue May 17 2016

Expect a fairly tranquil conditions for this part of the forecast.
A mid level ridge moving into the region is expected to keep the
forecast area dry into the early part of next week. Surface high
pressure to the east will drift slowly to the east, allowing high
temperatures to warm to near normal by Thursday and remain within
a few degrees of normal through the end of the forecast period.
