updated aviation portion for 12z TAF issuance

Short term Today... Tonight... And Saturday
issued at 327 am cdt Fri aug 18 2017
cloud trends today into this evening and small precipitation
chances late today the focus of this period.

Satellite imagery shows plenty of clouds over the state early this
morning in the cyclonic flow, with a few temporary holes opening
up over parts of eastern wisconsin at times. As the system pulls
away today into this evening, anticipate some decrease in clouds
from southwest to northeast. However how much of a decrease in the
clouds today is a challenge due to weak pieces of energy in the
northwest flow over the northern plains may work into parts of
western or southwest wisconsin later this afternoon and evening,
and may reach central areas as well. Mid to high level clouds
arriving from the west and surface dewpoints in the upper 50s
creating CU rule parameters in the broken category may keep clouds
around. Steep low level rates and up to 200 j kg capes today
suggests the potential of minor convection. Will leave the
forecast dry for now due to the coverage may be too small, but
will brief the next shift of the possible need for a small pop for
later today.

What clouds hang around this evening will be on the decrease
tonight as the upper ridge builds into the western great lakes
region and surface high pressure area settling over the area.

Clearing skies tonight along with surface dewpoints still in the
55 to 60 range, combined with lighter winds, may lead to fog
formation overnight. Weak southwest flow Saturday will bring
warmer temperatures along with more sunshine.

Long term Saturday night through Thursday
issued at 327 am cdt Fri aug 18 2017
dry conditions are expected across the region Saturday night into
Sunday as high pressure remains in place across our area. A warm
front will bring active weather to the region in the evening on
Sunday and through the overnight hours. A few strong thunderstorms
will be possible in western wisconsin as convective temperatures
are reached, but with little upper level support, currently expect
storms to quickly diminish overnight to showers.

Better upper level support arrives for Monday as a shortwave
moves through the region with the passage of a cold front.

Its too early to comment heavily on severe potential, as outflow,
cloud cover, and potential showers from Sunday will play a role in
determining how things shape up Monday. That said, models continue
to place high moisture values into the region ahead of this system
so heavy rainfall is likely.

Following the active weather early in the week, northwesterly
flow and mostly dry conditions return to region ahead of the next
upper level ridge. Temperatures through the period will trend
higher than normal Monday before coming closer to normal by the
end of the week.

Aviation For 12z TAF issuance
issued at 422 am cdt Fri aug 18 2017
early this morning, ceilings ranged from ifr across
north central wisconsin to MVFR elsewhere. Patchy MVFR vsbys due
to light rain, drizzle and fog also noted across far north
central wisconsin early this morning. Conditions expected to
improve toVFR conditions from southwest to northeast this
morning as a low pressure system departs northeast of the great
lakes region, and then remainVFR tonight. Clearing skies with
light winds may lead to patchy ifr MVFR vsbys due to fog late
tonight.

Grb watches warnings advisories
None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
