Discussion
Tonight through Friday night... Forecast confidence medium.

The breezy wly winds will cease by early evening as the mixing
ends and a ridge of high pressure approaches. The high will shift
ewd on Fri while an occluded low will track from the NRN great
plains into ontario, canada by 12z sat. The warm front will
approach on Fri with 850-700 mb warm, moist advection and
frontogenesis occurring. Thus light to briefly mdt rain is
expected during the day, however the warm front and pws of 1.7
inches will move into SRN wi by late afternoon and evening. The
llj will slowly veer through the night with continued moisture
transport and minimal corfidi vector motion. Thus repeated rounds
of showers and thunderstorms are expected to develop over SRN wi
and NRN il. Flash flooding is a concern along with a marginal to
slight risk of svr storms. The flooding potential and svr
potential will be highest along and south of a line from mineral
point to madison to port washington. Will issue a hydrologic
outlook for now but a flash flood watch is possible in later
forecasts.

Saturday and Sunday - confidence... Medium
main forcing expected to be in the morning as shortwave and frontal
boundary move through. Highest pops will be in the southeast cwa.

The gfs, and to a lesser extent, the gem, redevelop diurnally driven.

Scattered type activity in parts of the western northern cwa. None
of the models are taking the front to our south. So with enough
sunshine and instability buildup we could see this activity redevelop
in the afternoon. The front is then proggd to swing through Saturday
night with a continued chance of shra tsra. The surface 850 front
will then exit the southeast Sunday morning with precip chances in
the south gradually ending.

Sunday afternoon and Sunday night - confidence... Medium
looking at squeezing in a little better shot of dry weather this period
as a ridge of high pressure puts a brief halt to organized rainfall.

Will have to watch later Sunday night as return WAA pattern sets up
pretty quick, so some activity could sneak into western areas later
in the night.

Monday through Wednesday - confidence... Medium
active pattern shaping up as a warm air advection regime takes
hold Monday with low pressure in the northern plains. Should get
at least one round of convection in the morning into the early
afternoon hours Monday at the time of greatest WAA in combo with a
shortwave. May get a relative minimum in organized precip Monday
night into Tuesday as we await the ejection of of main mid level
energy wave. This should result in more storms Tuesday night and
possibly into Wednesday per insinuation of 00z ecmwf. So active,
unsettled pattern to continue.

Wednesday night and Thursday - confidence... Medium
looks like things will settle down. Weak front trough axis could
kick off some showers storms Thursday.

Aviation(21z tafs) Vfr conditions tnt then showers and isolated
tstorms will overspread SRN wi Fri am into the early afternoon with
cigs of 1-3 kft developing. MVFR vsbys will occur with the precip.

At times.

Marine A small craft advisory remains in effect until 8 pm for breezy
west winds. Much lighter winds are then expected for tnt- Fri with winds
becoming ely. The winds will then veer to sly for late Fri nt-sat but
remain below small craft advisory conditions.

Mkx watches warnings advisories
Wi... None.

Lm... Small craft advisory until 8 pm cdt this evening for lmz643>646.

Tonight through Friday night aviation marine... Gehring
Saturday through Thursday... Collar

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.
