Area Forecast Discussion...UPDATED
National Weather Service Milwaukee/Sullivan WI
657 AM CDT Sat Jul 22 2017

.UPDATE...

Rain moved out of southern WI. Thus, the flash flood watch was
canceled. We are still waiting to hear about the flooding
conditions in Lafayette County. The Flash Flood Warning remains in
effect.

Patchy fog and low clouds will gradually improve through
mid morning.

There is a weak wake low that developed over northern IL. South
wind gusts to 35 mph have been observed. It looks like these gusty
southerly winds will remain confined to the WI/IL border area.

&&

.AVIATION(12Z TAFS)...

IFR ceilings will rise quickly this morning to MVFR and then VFR
by early afternoon. Expect scattered to broken skies all day.
There is only a small chance for thunderstorms toward southeast WI
this afternoon and toward Fond du Lac tonight, so did not mention
in TAFs.

Another round of patchy fog is expected early Sunday morning.
Otherwise VFR conditions will prevail.

.PREV DISCUSSION... (Issued 401 AM CDT Sat Jul 22 2017)

SUNDAY THROUGH FRIDAY...Forecast confidence is high.

Didn`t focus too heavily on the extended given the ongoing flooding
concerns tonight. There is a small chance for a shower or storm on
Sunday as a weak cold front moves through. Thereafter, expect quiet
and dry weather on Monday and Tuesday, with high pressure in
control. Our next shot for showers and storms is on Tuesday night
into Wednesday morning as a cold front sweeps through. High pressure
returns into Thursday morning, with shower and thunderstorm chances
returning later Thursday into Friday. Look for slightly below normal
temperatures on Monday into Tuesday, trending towards normal
thereafter.

AVIATION(06Z TAFS)...

Showers and a few thunderstorms may affect eastern and far
southwestern portions of the area for the next few hours.
Otherwise, light winds are expected overnight. Low ceilings down
to 600 feet or so are expected into early this morning, before
rising above 3000 feet this afternoon. Visibility values should
drop down to 1 to 2 miles at times between 09Z and 13Z Saturday as
well, possibly lower in low lying areas. These should improve
above 6 miles by middle to late morning as well.

There are small chances for showers and thunderstorms this
afternoon into tonight across portions of the area. For now, left
mention out of TAFs due to low confidence. Light north to
northeast winds are expected Saturday, with light west winds
Saturday night. There is some possibility of low ceilings and
visibilities with fog once again later tonight. For now, not
confident enough to go with lower values at this time.

MARINE...

Fog is possible through mid morning. North winds will increase
Sunday night and Monday but are expected to remain below small
craft levels.
