updated aviation portion for 12z TAF issuance

Short term Today... Tonight... And Thursday
issued at 327 am cdt Wed oct 16 2019
gusty northwest winds will continue across the western great lakes
today as the area resides between a departing low to the east and
a high building in from the west. Wind gusts over door county
could approach 50 mph at times, therefore will continue the wind
advisory for this area given the increased wind flow across the
peninsula. For the rest of the lakeshore counties and east-central
wisconsin winds could gust to 35 to 45 mph at times. Although
gusts could approach wind advisory criteria, it should be short
lived enough to not necessitate the expansion of the current
headline.

Besides the wind, the chance for showers will linger through the
afternoon hours as several shortwaves track through the western
great lakes with an added boost of moisture from lake superior for
far north-central wisconsin given the north-northwesterly winds.

Highs today will be well below normal, ranging from the lower to
middle 40s across the north, with highs around 50 across east-
central wisconsin.

High pressure will then bring drier weather into the region
tonight as winds ease considerably after sunset. Lows tonight will
generally be in the 30s. Dry weather is expected to continue into
Thursday with a gradual warmup and some sunshine expected by the
afternoon hours. Highs during the afternoon are expected to rise
into the upper 40s to lower 50s.

Long term Thursday night through Tuesday
issued at 327 am cdt Wed oct 16 2019
surface high pressure and a mid level ridge should keep the
forecast area dry through Friday. Showers arrive Friday night and
continue on Saturday as a cold front approaches and then passes
through wisconsin. Dry conditions should return for Saturday night
and Sunday as high pressure moves across the region. Another,
stronger, surface system and mid level trough will bring showers,
and possibly some thunderstorms, back to the area starting Sunday
night. The best chance for precipitation will be Monday into
Monday evening before rain chances start to taper off on Tuesday.

Expect above normal temperatures into early next week, before
colder air arrives on Tuesday in the wake of the passing cold
front.

Aviation For 12z TAF issuance
issued at 619 am cdt Wed oct 16 2019
scattered showers will continue this morning, mainly across
northern and eastern wisconsin, as a low pressure system continues
to exit the region. Gusty northwest winds are expected today with
a tight pressure gradient between the departing low and an
approaching high. Showers will end this afternoon as high
pressure approaches from the west with winds dying down this
evening with a looser pressure gradient. MVFR conditions are
expected to improve toVFR across much of the area, save for
north-central wisconsin with a continued feed of moisture off lake
superior. MVFR CIGS may return across central wisconsin later
tonight as an inversion lowers ceiling heights.

Marine
Issued at 327 am cdt Wed oct 16 2019
a tight pressure gradient will cause northwest winds to gust to
gale force today as the region is between a departing low to the
east and a high building in from the west. A gale warning
continues for the entire area through early this evening. Winds
will gradually subside later this afternoon into this evening.

Grb watches warnings advisories
Wind advisory until 7 pm cdt this evening for wiz022.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
