Updated aviation portion for 00Z TAF issuance

.SHORT TERM...Tonight and Monday
Issued at 310 PM CDT Sun Oct 15 2017

The main concern tonight is frost potential. Clouds and scattered
showers/sprinkles across the area should exit late this afternoon
or early during the evening. There should be a period of mostly
clear skies before an approaching trough brings more clouds
tonight. These clouds should exit to the east overnight, and
plenty of sunshine is expected for Monday.

The surface pressure gradient will continue to weaken as a
departing surface low gets farther away from Wisconsin. Also,
winds are likely to decouple during the night and should become

The lack of clouds combined with light winds will allow areas of
frost to develop west of the Fox Valley. Northern, and parts of
central Wisconsin are likely to see widespread frost. Advisories
have been discontinued across the north but need to be issued for
the counties of: Marathon, Wood and Portage for late tonight into
early Monday morning.

Sunshine on Monday will allow for warmer high temperatures than
those experienced today.

.LONG TERM...Monday Night Through Sunday
Issued at 310 PM CDT Sun Oct 15 2017

Mild and dry weather expected this week, as the upper
flow is nearly zonal and there is little moisture. Highs by Thursday
or Friday could be in the 70s in eastern Wisconsin. The dry weather
will make for good conditions for farm and yard work this week.
