Short term
Tonight through Friday... Forecast confidence medium.

Sly flow and warm advection will begin tnt but will increase on
wed when a strong sly LLJ to the west veers to swly at 50-60 kts
as it shifts ewd across SRN wi. A shortwave trough will pass
during this time providing upper support. So overall, moderate to
strong warm advection and q-vector convergence expected for wed
and lingering into Wed eve. The CAPE will not become appreciable
until late Wed aft-eve although sfc based convection is
questionable due to clouds and cooler temps during the daytime
hours. Thus the best chances for strong or severe storms will be
the evening as warm, moist advection continues via a veering llj.

If sfc based convection does occur then all severe threats
including tornadoes would be possible. Some concern for training
convection Wed eve due to the veering LLJ becoming more aligned
with the upper flow, so at least a minor flash flood threat will
be possible. A cold front will gradually pass late Wed nt-thu am
with the focus for convection remaining mostly over il ia for thu
and Thu eve, although will still mention chances of tstorms due to
close proximity to the front.

A shortwave trough and compact sfc low will track into SE wi late
thu nt and Fri am bringing widespread showers and tstorms to srn
wi. The severe threat will likely stay south where higher cape
values will be present. The average rainfall expected through fri
will range from 1.40-2.25 inches with the usual locally higher
amounts. Some rivers may reach minor flood stage due to this.

Long term Saturday through Tuesday... Forecast confidence low to
medium.

A fairly large upper trough will reside over ontario, canada and
the NRN great lakes for the weekend. Shortwave troughs will rotate
around the large upper trough into SRN wi bringing chances of
showers and tstorms. For early next week it appears a shortwave
trough and low pressure area will remain mainly to the south as it
tracks ewd.

Aviation(18z tafs) Sct060 cumulus this afternoon and broken at
times through the middle of the afternoon in far ERN wi.

Otherwise mo clear skies andVFR conditions tnt until early
morning west of kmsn where clouds will increase ahead of an
approaching area of showers and tstorms. Llws will develop over
south central wi during this time but will dissipate by late
morning on Wed as breezy sly winds develop at the surface. An area
of showers and sct tstorms will move ewd across SRN wi through
the day with additional development of strong to severe storms wed
eve. Areas of MVFR CIGS and vsbys will be possible around and
after any showers or storms. Much lower CIGS and vsbys within
tstorms.

Marine A small craft advisory is in effect for wed-wed nt due
to breezy sly winds and high waves on Wed with the breezy winds
shifting swly for Wed nt.

Beaches A beach hazard statement will likely be needed for
wed-wed eve due to breezy sly winds and high waves. Dangerous
structural and longshore currents will likely develop.

Mkx watches warnings advisories
Wi... None.

Lm... Small craft advisory from 9 am Wednesday to 6 am cdt Thursday
for lmz643>646.

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.
