updated aviation portion for 00z TAF issuance

Short term Tonight and Saturday
issued at 315 pm cst Fri nov 16 2018
the main forecast concern is snowfall trends and totals with
the system approaching from the northern plains.

Models have trended south with the low pressure system and lower
with the associated QPF snowfall that will impact the region in
the late evening and overnight hours, then exit early Saturday.

The snow will mainly impact our southern two tiers of counties
(central and east central wi), with the highest totals (1 to 1.5
inches) occurring over southern wood, waushara, winnebago,
calumet and manitowoc counties.

A second are of snowfall will occur over vilas county and far
north central wi due to lake-effect. Lake-h8 delta-t's will
increase to 20+ c as CAA occurs tonight, and winds will turn
to a favorable nnw trajectory. Have increased pops to likely
over northwest vilas county, and bumped snowfall accumulations
to around 2 inches there. The lake-effect should taper off
Saturday afternoon as canadian high pressure pushes into
the region.

Lows tonight are expected to drop into the upper teens to upper
20s. Highs on Saturday will range from the 20s northwest to the
lower 30s southeast.

Long term Saturday night through Friday
issued at 315 pm cst Fri nov 16 2018
the main concerns for this forecast period are the chances for
precipitation for Monday and Tuesday. Below normal temperatures
will also continue through Tuesday.

A surface high pressure system positioned over the central plains
tracks to the southeast during the start of this period, allowing
for the transition to a northwest upper-level flow on Sunday. As
the high pressure continues to track further southeast on Sunday
night, a surface clipper system begins to move southeast across
the dakotas. This clipper system poses as the next precipitation
maker for wisconsin into Monday morning. There is much uncertainty
with the track of this system amongst the models, as well as the
amount of moisture associated with it. Due to this uncertainty,
kept a blend of the model guidance chance pops of snow showers
across the majority of the forecast area ending Monday afternoon.

Once the clipper system exits to the east Monday evening, a weak
area of surface high pressure tries to move into the upper
mississippi valley. The ECMWF and the canadian indicate another
quick moving clipper system will pass over lake superior,
bringing a small chance for some precipitation across far
north-central wisconsin Tuesday evening. The GFS does not
indicate this clipper system will impact the area and stay further
north. Therefore, kept small chances for precipitation across far
north-central wisconsin.

An area of high pressure will then position itself over ontario,
as the clipper system exits to the east on Wednesday, resulting in
dry conditions through thanksgiving. This pattern will also
allow for warmer air to push into the area on Wednesday and
thanksgiving, bringing high temperatures back to normal.

Aviation For 00z TAF issuance
issued at 544 pm cst Fri nov 16 2018
widespread MVFR ceilings covered the region early this evening,
with a few spots just above 3k ft. Although clearing appears
unlikely this evening, a slight improvement in ceiling heights
may occur due to the arrival of drier air at the surface.

Low pressure will impact the region during the late evening and
overnight hours, but is expected to track farther south than
previously thought. Light snow and associated MVFR local ifr
conditions with this system should only impact areas south of a
line from marshfield to green bay. The snow will end later
tonight into early Saturday, but MVFR or low-endVFR ceilings
should prevail through midday.

Gusty west-northwest winds will subside early this evening.

Grb watches warnings advisories
None.

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.
