updated aviation portion for 18z TAF issuance

Short term Today... Tonight... And Wednesday
issued at 318 am cdt Tue sep 26 2017
although the precise location was hard to discern, a cold front
appeared to bisect the forecast area from central wi into
northeast wi early this morning. Radar indicated scattered showers
along and behind the cold front, though much more widespread
rain was occurring over the eastern dakotas, mn and western ia,
closer to dynamic support from a large upper trof and the rrq of
a strong upper jet. Moisture was plentiful, with pwats of
1.50-1.75 inches near and behind the boundary. A weak surface
low was lifting northeast through far southeast mn and northeast
ia, along the frontal boundary.

Showers will increase across the region as the surface low
deepens and lifts northeast through wi, and drags the cold front
through the forecast area. Will carry likely pops across the
forecast area, with showers decreasing from west to east during
the late afternoon and early evening. Instability will be very
marginal, so will only mention isolated thunderstorms today.

Temperatures will vary significantly across the region, with
highs ranging from the mid to upper 60s in north central wi to
around 80 southeast.

Expecting mainly dry conditions later tonight into Wednesday,
with a gradual decrease in clouds during the period. The most
substantial change will be a return to normal or slightly below
normal temperatures. Lows tonight will be in the 40s to lower
50s, with highs on Wednesday in the upper 50s to middle 60s.

Long term Wednesday night through Monday
issued at 318 am cdt Tue sep 26 2017
the latest GFS ensemble mean indicates a general deamplification
of the upper air pattern over the next week. After a brief cool
down later this week, guidance indicates that above normal mid-
level heights will return to the western great lakes.

Wednesday night through Thursday night... Flattened troughing will be
present overhead on Wednesday night. If there are any weak
shortwaves moving through, high pressure at the surface and ample
dry air should prohibit precip. Better chances of showers will
arrive on Thursday into Thursday night when a fairly robust
shortwave dives southeast into the region. Highest precip chances
look to occur over northern wi. Temps will be seasonable over the
period.

Rest of the forecast... Clouds and scattered showers will likely
linger into Friday morning over northern wi. Then clearing should
occur on Friday afternoon into Friday evening. Friday looks to be
the coolest day over the next week. High pressure will then
reassert itself for next weekend, which looks mainly dry and
comfortable. The next chance of precip will occur with the next
frontal passage early next week. Early indications are that temps,
in general, look to be above normal for much of next week.

Aviation For 18z TAF issuance
issued at 1123 am cdt Tue sep 26 2017
scattered showers and isolated thunderstorms will continue across
much of northeast wi this afternoon as a cold front slowly moves
to the east. The onset of cooler air behind the frontal passage
will bring a period of low clouds to much of the region tonight,
although how far south and east these low clouds can get is still
up for debate among the models. Expect these MVFR ifr CIGS to
reach at least the rhi, auw and CWA taf sites tonight. High
pressure is forecast to build into the region on Wednesday,
bringing a return toVFR conditions by mid-morning and continuing
for the rest of the day.

Grb watches warnings advisories
None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
