Updated aviation portion for 12Z TAF issuance

.SHORT TERM...Today...Tonight...and Sunday
Issued at 257 AM CDT Sat Jul 21 2018

Although showers and thunderstorms are much less numerous early
this morning, activity is expected to pick up during the daytime
hours as PV anomalies rotate around an upper level low situated
over the south central Great Lakes with daytime heating causing an
increase in instability across the region. The best chance for
rain will be across the east closer to the upper level low,
otherwise it will be hard to pinpoint timing and location of
storms as they will be convective in nature and will come and go
in waves. Instability isn`t all that impressive, only a few
hundred J/kg, however low level winds will be a bit better than
yesterday. Any storms that form could produce locally heavy
rainfall and some gusty winds to 30 to 40 mph, which is well
below severe limits.

Precipitation chances will slowly diminish later tonight into
Sunday morning as ridging makes its way over the western Great
Lakes region. The sun should break out sometime Sunday afternoon
as drier air makes its way over the region.

Highs today under a shroud of clouds will generally only be in the
70s across the south, with highs around 70 across the north. Lows
tonight will range from the upper 50s across the north with middle
60s across the southeast. By Sunday highs will rebound into the
middle to upper 70s across the north, with highs around 80 in
central and east-central Wisconsin away from Lake Michigan.

.LONG TERM...Sunday Night Through Friday
Issued at 257 AM CDT Sat Jul 21 2018

A cold front will approach Northeast WI on Monday and bring a
chance for showers and a thunderstorm or two. After that, another
front will bring a chance for showers on Wednesday.

Long term models indicate that the current broader upper level
pattern, with high pressure over the western U.S. and low pressure
troughing over the Great Lakes, will essentially remain unchanged
through the end of the July. This means that chances for
precipitation will continue to occur in the extended forecast;
computer models smear 20-40 pops across Northeast WI from Tuesday
through Saturday.

Expect high temperatures to be within about 5 degree of normal
through the week.

.AVIATION...for 12Z TAF Issuance
Issued at 559 AM CDT Sat Jul 21 2018

The low pressure system centered over southern Lake Michigan will
drift slowly toward the southeast and continue to produce less-
than-ideal weather conditions for VFR flights in Northeast
Wisconsin throughout the day today. Chances for showers and
thunderstorms will increase by afternoon and northerly surface winds
will gust close to 20 kts all day and into tonight.

.KOSH...low cigs, IFR or near IFR, will be a problem this morning,
possibly continuing into the afternoon with periods of showers
expected and possibly a thunderstorm. Gusty winds out of the
north-northeast are expected all day and well into the evening.
