dense fog advisory will continue unchanged with the morning
forecast issuance. ASOS awos sites were reporting widespread vsbys
of 1 4sm on the 400 am obs. Webcams were not quite as ominous
looking. But expected the fog to continue to thicken since there's
still 2 1 2 hours until sunrise. In addition, the worst
conditions in terms of visibility for travel typically occur for
an hour or so after sunrise. Complete forecast discussion will
follow a little later this morning.

Aviation For 06z TAF issuance
issued at 1020 pm cdt Thu sep 19 2019
an upper level disturbance and associated showers will exit far
northeast wi at the beginning of the TAF period. Otherwise it
will be difficult to pinpoint precipitation trends in an air
mass with plenty of moisture, but little forcing. Will not include
any mention of precipitation in the tafs at this time.

Models show fog developing overnight through late Friday morning.

Expect lifr vlifr conditions at rhi auw cwa, and ifr lifr at
grb atw mtw. Expect the foggy conditions to improve between 14z-
16z fri, with any lingering low stratus layer gradually rising
during the daytime period.

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.
