updated aviation portion for 00z TAF issuance

Short term Tonight and Sunday
issued at 250 pm cst Sat feb 17 2018
first round of light snow was moving across northeast wisconsin as
of mid afternoon. The light snow should end around 6 pm along the
lake michigan shoreline. Accumulations should be around an inch or
less, skies should clear fairly quickly this evening behind the
snow. This should allow temperatures to plummet, especially in our
typical cold spots later tonight as the winds go fairly light.

Temperatures should not do a complete tank as mid and high clouds
will be on the increase again late tonight into Sunday morning.

On Sunday, the main question is how far south snow will make into
northern wisconsin. The NAM is farther north than the ecmwf,
gfs and canadian model. Snow should arrive across the far north
late Sunday morning and continue through the afternoon. Currently
have an inch or two for this period. No precipitation is expected
south of a merrill to sturgeon bay line. Only minor changes made
to the MAX temperatures on Sunday.

Long term Sunday night through Saturday
issued at 250 pm cst Sat feb 17 2018
snow will be winding down Sunday evening as the 850 mb low slides
over lake superior, dragging a cold front south in its wake. How
far south this cold front tracks through the early part of the
new work week will play a role on the precipitation type and will
present a big forecast challenge.

There is an increasing potential of mixed precipitation with ice
accumulation becoming more of a concern. Considered a watch due
to the potential for ice accumulation but precipitation may hold
off more toward Monday night. Progs this morning suggests two main
frontal waves, Monday afternoon and then again Tuesday afternoon
and evening. Even between these two primary regions of
precipitation, lighter precipitation will likely continue to be an
impact, such as continued freezing drizzle.

High pressure dropping into the mid section of the country will
bring quieter conditions to the area with the next chance for
precipitation toward the end of the week.

Aviation For 00z TAF issuance
issued at 601 pm cst Sat feb 17 2018
the band of light snow that brought ifr conditions to much of the
area this afternoon has now shifted east. Some low-end MVFR cigs
were lingering in its wake, but low levels are expected to dry out
overnight. That should lead to a brief period of clear mostly
clear skies before middle clouds spread back in from the west. The
precipitation with an initial wave riding northeast in developing
southwest upper flow will clip the north tomorrow, leading to some
MVFR and possibly ifr conditions during the mid-day hours.

Otherwise, the main aviation weather concern will be the
development of fairly strong llws as winds above the surface
increase to near 50 kts.

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.
