Update
Forecast is on track this evening. Very light flurries will
remain possible through the rest of tonight, but no impacts are
expected. Temperatures will continue to fall through the teens, on
the way to overnight lows in the single digits.

Marine
Winds will increase from the southwest tomorrow morning, with
frequent gusts around 30 kt through the day. A few gale force
gusts are also possible. A small craft advisory will be in effect
from mid morning Wednesday through Thursday afternoon.

update...

no changes at this time. An area of light flurries will push south
through the region over the next few hours. No impacts are
expected.

Aviation(00z tafs)...

a few flurries will be possible this evening, but no significant
impacts are expected. VFR will prevail.

Winds will increase from the southwest tomorrow, especially during
the afternoon hours, when a few gusts between 25 and 30 knots will
be possible. This could lead to some blowing and drifting of snow.

While visibility may not be significantly restricted, clearing of
runways taxiways may become necessary. Winds will decrease a bit
tomorrow evening, but remain rather gusty. Llws will also be an
issue tomorrow evening night.

discussion...

tonight through Thursday... Forecast confidence is high.

Generally quiet weather is expected. The one problem for Wednesday
into Thursday will be the increasing west to southwest winds. Low
pressure to our north and high pressure to the south, puts us
squarely in a tight pressure gradient. We should see sustained
winds of 15 to 20 mph with gusts to 30 and possibly 35 mph up
toward sheboygan for Wed afternoon into Thursday. This should
result in considerable drifting snow, causing difficult travel,
especially in the more north south oriented roads.

Temperatures will be in the 20s on Wednesday, warming into the
lower and mid 30s on Thursday with the milder southwest flow.

Friday and Saturday... Forecast confidence is high.

Our quiet and progressively milder trend will continue as the flow
turns more zonal then southwest with time. We could have highs in
the lower 40s by Saturday.

Sunday and Monday... Forecast confidence is medium.

The long range guidance has a storm system rolling through the
upper midwest later in the weekend into early next week. Both the
gfs and the ECMWF have the track pretty far to the west and north,
thus we get into the warm sector of this storm. Timing is off a
bit from each model, but not bad for this far out. High temps in
the 40s through the weekend would result in a wintry mix early,
transitioning to rain, then back to snow. It's a very long way off
in the meteorology world and this track will continue to
fluctuate with time. But, right now, this is not a big snow
producer for southern wisconsin. Stay tuned.

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.
