Discussion
Today and tonight... Forecast confidence is high.

Strong low pressure will continue ewd across ontario, canada, then
newd across quebec, canada. A 100-120 kt nly jet will drive the
upper trough axis across SRN wi this afternoon with the strong
cold frontal passage this morning. High temps will occur early
this morning then fall through the morning, but becoming steady
in the lower to middle 30s for the afternoon. Wind gusts to 30 mph
are expected. The broken stratocumulus behind the cold front over
mn should also develop sewd via the upper trough being driven swd
by the upper jet. The stratocumulus should then gradually decrease
from west to east during the afternoon but a few flurries could
occur. For tnt, the core of the polar high will track swd through
the great plains but its sfc ridge will extend nwd into the upper
ms river valley by 12z wed. Thus expect winds to become lighter
through the night but not decouple. Lows in the upper teens to
lower 20s expected.

Wednesday - confidence... Medium
some modification of low level thermal trough expected with winds
swinging around to more of a west or southwest direction. The
surface ridge axis starts off the day across ia mn and then leans
more into the oh valley by days end. This will set the stage for
the return flow. Not ready to jump on the wet NAM solution for
Wednesday night in this WAA regime.

Thanksgiving - confidence... Medium
a weak surface 850 trough passes through then the flow reloads
from the southwest as next low approaches from the northern
plains. Looks like a steady period of modifying 925 temps right
into Thursday night.

Friday - confidence... Medium
thermal ridge amplifies ahead of the cold front. Should see many
temps reach the 50 degree mark with gusty southwest winds ahead
of the front. Could go even higher with ample sun, however cloud
cover and rain chances will be on the increase during the
afternoon evening with the frontal boundary working through.

Saturday and Sunday - confidence... Medium
looking at a colder but dry weekend as northwest winds usher in
the chilly airmass. Windiest day is shaping up to be Saturday. As
Sunday wears along the surface ridge axis is proggd to shift
right across the state so that will make for a much lighter wind
regime.

Monday - confidence... Medium
the high will end up in the ohio valley with a renewed southerly
flow setting up yet another low taking shape in the plains. So we
should see some modification to the weekend chill though the south
winds will be gusty and the warmest 925 temps hold off to the west
and southwest of wi.

Aviation(09z tafs) Stratocumulus will develop after sunrise
and in the wake of a cold front. Bkn025-035 is expected by late
morning which will continue into the afternoon. However, enough
dry air and subsidence will lead to decreasing clouds from west to
east across SRN wi during the afternoon. Gusty wly winds this
morning will become nwly by late morning with the passage of the
cold front.

Marine A small craft advisory is now in effect until 9 pm tnt
for brisk wly winds becoming nwly by late this morning. The
pressure gradient and unstable conditions over the lake will help
maintain wind gusts into this evening. High waves are expected
over the open waters.

Mkx watches warnings advisories
Wi... None.

Lm... Small craft advisory until 9 pm cst this evening for lmz643>646.

Today tonight and aviation marine... Gehring
Wednesday through Monday... Collar

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.
