Short term Tonight and Tuesday
issued at 245 pm cdt Mon sep 16 2019
skies were mostly sunny this afternoon away from lake
michigan. Temperatures were in the 70s to lower 80s away
from lake michigan. It was mostly cloudy to cloudy with
areas of fog with temperatures only in the 60s near the lake.
For tonight, high pressure will gradually shift east of the
area late tonight. The combination of light winds and clear
skies combined with abundant low level moisture should allow
fog to form across northeast and east-central wisconsin. The fog
may be dense at times, especially near lake michigan. Across
central and north-central wisconsin, low level winds are expected
to increase through the night. This should keep the fog from
becoming widespread dense in this region along with a low stratus
deck expected. Would not be surprised if a dense fog advisory
would be needed later this evening across northeast and east-
central wisconsin. Did not stray far from guidance for lows
Any low clouds and fog should burn by mid morning on Tuesday.
The only exception will be near the bay and lake where the fog
will take longer to burn off. The fog may linger through much
of the afternoon near lake michigan. Numerical guidance in good
agreement and followed. Went a degree or two lower near lake
michigan due to southeast flow, clouds and fog.
Long term Tuesday night through Monday
issued at 245 pm cdt Mon sep 16 2019|
some fog is possible Tuesday night, though conditions are not as
favorable as the last couple days. Warm and dry weather is
expected Tuesday night through Wednesday afternoon with high and
low temperatures about 10 degrees above normal.
A weak cold front may bring showers and thunderstorms Wednesday
afternoon through Thursday. It should stall somewhere over the
south half of wisconsin Thursday, with additional shower chances
Friday and Saturday as it moves back north. Temperatures will be
well above normal.
Aviation For 18z TAF issuance
issued at 1202 pm cdt Mon sep 16 2019
MVFR ifr conditions should dissipate early this afternoon across
northeast wisconsin, except near lake michigan where low clouds
and fog should remain near lake michigan. The low clouds and
fog could impact the kmtw TAF site through late tomorrow morning.
Otherwise,VFR conditions expected over the remainder of the
region this afternoon into this evening. Later tonight, ifr MVFR
cigs or visibilities due to fog are expected after 03z and
continue through mid morning on Tuesday. Low level winds around
1,000 feet above the ground should prevent the fog to become
widespread dense across north-central wisconsin. A little more
iffy if dense fog would form at kcwa kauw TAF sites late tonight.
Any fog should burn off by 15-16z on Tuesday.VFR conditions
expected Tuesday afternoon.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
