Update Increasing low level winds from the north has dissipated
most of the fog across southern wi. However these winds continue
to pull in colder air from the north. Getting reports of a
rain graupel mix in the fond du lac area, which supports the
influx of the colder air. Probably some mix falling in the higher
dbz in sauk county. Still expect a rain snow mix to spread across
the area from now through mid-morning. South central wi has best
chance of some light slushy accumulations.

Aviation(12z tafs) Some rise in ceilings across eastern cwa
early this morning, but expect these to lower back to MVFR ifr as
precipitation spreads across the area.

Prev discussion (issued 332 am cst Sat nov 18 2017)
discussion...

today - confidence... Medium.

Gfs ECMWF blend used as this guidance showing much better run to run
consistency and agreement versus nam. Strengthening low pressure
passing by well to the south today. Associated with the low is a
sharpening mid-level short wave and area of mid-level
frontogenetical forcing that will pass across southern wisconsin
this morning. Increasing northerly winds in the low levels will
pull colder air across southern wisconsin through the morning.

Forecast soundings show likely potential for initial surge of rain
becoming mixed with or changing over to wet snow for an hour or two
between 12z and 15z, especially over south central wi. Pavement
temperatures will remain above freezing, but strength of sloping
frontogenetical forcing may result in a burst of wet snow and
reduced visibilities with rapid accumulations on grassy and colder
surfaces. The snow may change back over to light rain or drizzle
before ending later this morning and early afternoon.

Tonight - confidence... Medium to high.

Dry and blustery conditions are expected tonight as the colder air
settles over the region. Some lower clouds may stick around for
awhile in the cold northwest flow.

Sunday through Friday - confidence... Medium to high
overall quiet period with main forecast focus on temperature
swings. We're seeing a nice uptick in temps for Monday then a
potent mid level trough drops in for Tuesday with a pronounced
surge of cold air advection. After that a moderating temp trend is
expected right through Friday. 925 temps are proggd to really ramp
up heading into Friday. A long ways off though enough support in
the guidance to suggest superblend highs may be too low so a
collaborative boost was given to the Friday high temps.

Aviation (09z tafs)... Ceilings and visibilities will vary from ifr
to MVFR this morning, gradually improving toVFR this afternoon and
tonight. Blustery north winds will develop this morning.

Marine... Wave heights most likely have subsided below 5 feet across
northern marine zone. Hence wl cancel small craft advisory an hour
early. Otherwise, low pressure passing to the south will result in
a tightening pressure gradient and strengthening north winds this
morning. The strong winds will continue through tonight but will
gradually east. Gusts to 35 knots are expected to develop later
this morning, and continuing into tonight. Hence status quo on gale
warning which begins at 15z this morning and lasts through the
evening. Small craft advisory conditions will likely continue
later tonight, possibly into Sunday morning.

Mkx watches warnings advisories
Wi... None.

Lm... Gale warning from 9 am this morning to midnight cst tonight for
lmz643>646.

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.
