updated aviation portion for 00z TAF issuance

Short term Tonight and Wednesday
issued at 234 pm cdt Tue aug 21 2018
a relatively cool day for late august as temperatures were in
the lower to middle 60s north, and around 70 south under mostly
cloudy skies.

Skies will become mostly clear across the northwest half of the
forecast area late this afternoon and across east-central
wisconsin early this evening. There should be enough dry air and
winds to prevent any fog across the far north tonight. It will be
cool with lows in the lower to middle 40s north to the lower to
middle 50s south, except near 60 across northern door county.

Skies will start out sunny on Wednesday, with fair weather cumulus
clouds developing by late morning or early afternoon and then
continuing through the afternoon. It will be warmer with highs
mainly in the 70s.

Long term Wednesday night through Tuesday
issued at 234 pm cdt Tue aug 21 2018
quiet weather is expected Wednesday night into Thursday, with
rain returning late Thursday night into Friday, and warmer, more
humid and stormy conditions for the weekend and early next week.

High pressure will bring a period of dry and pleasant weather
through Thursday. Temperatures should be close to normal.

There are still timing issues related to the arrival of return
flow precipitation Thursday night into Friday, with the gfs
bringing precipitation across the entire forecast area Thursday
night, while the ECMWF keeps us dry. Have opted for the blended
approach at this time, which keeps the highest pops and QPF west
of the fox valley and lakeshore areas. Regardless, high pops are
warranted Friday into Friday night, as the surface 850 mb warm
fronts arrive on Friday, followed by a sharp upper level trof
Friday night. Elevated instability and increasing pwats will
support the threat of thunderstorms and locally heavy rainfall
during this period. Clouds and rain will hold temperatures back
on Friday, with highs only in the middle 60s to lower 70s.

There may be a lull in precipitation chances Saturday afternoon
and evening, due to subsidence behind the departing short-wave
and weak upper level ridging. A cold front will sag south through
the area Saturday night into Sunday. This front could trigger a
round of strong to severe thunderstorms over the region Sunday
afternoon and evening. An increasing low-level jet should continue
the threat of storms and heavy rain Sunday night into Monday
morning.

The frontal boundary is expected to lift back to the north as a
warm front early in the week, and reside in the vicinity of
northern wi, where it will provide a focus for additional
thunderstorm development.

Overall, the pattern is expected to be active, with potential for
a couple rounds of severe thunderstorms and heavy rainfall. Muggy
conditions and above normal temperatures can be expected from
Saturday through Tuesday.

Aviation For 00z TAF issuance
issued at 605 pm cdt Tue aug 21 2018
most CIGS have risen above MVFR levels late this afternoon.

Clearing is moving in relatively quickly over northwest wi, and
should push across the region through mid to late evening. Northerly
winds with gusts of 20 to 25 knots should also subside around
sunset. After skies clear, some patchy fog is possible across the
far north, especially at klnl. Fair weather cumulus clouds
expected to develop late Wednesday morning and continue Wednesday
afternoon. Winds on Wednesday will be lighter than today with
gusts around 15 knots from the northwest.

Marine
Issued at 234 pm cdt Tue aug 21 2018
gusty northerly winds were creating hazardous conditions on the
lake and bay this afternoon. Winds and waves will gradually
subside this evening.

Grb watches warnings advisories
Beach hazards statement until 7 pm cdt this evening for wiz040-
050.

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.
