updated aviation portion for 12z TAF issuance

Short term Today... Tonight... And Sunday
issued at 311 am cst Sat nov 18 2017
a cold front continues to slowly track through wisconsin this
morning. Before it tracks through, another area of precipitation
is slated to track through the southern portion of the CWA this
morning as noted by the regional doppler radar imagery. Although
precipitation type will mainly be liquid, some snow could mix in
at times as you head further north. Once this area of more
substantial moisture exits the region, mainly light snow or
drizzle is expected for the rest of the morning into the early
afternoon as this low pressure system exits to the east. Further
north, lake effect snow will begin to develop with the best
chances later this afternoon and into the overnight hours as winds
and delta t values become more favorable. Until the better
moisture arrives up north, some freezing drizzle is possible today
given the colder surface temperatures. Snowfall amounts from this
lake effect snow event should be relatively light, with around an
inch possible in vilas county through tonight. Highs today will
likely be in the morning or early afternoon, generally in the 30s,
then fall during the afternoon hours as colder air advects in
from the north. Lows tonight should dip down into the middle teens
across the north, with lower to middle 20s across the eastern
cwa.

The lake effect should come to an end later Sunday morning into
the afternoon hours as high pressure builds in across the upper
mississippi valley. Highs Sunday should range from the middle 20s
across the north, with around 30 across the eastern cwa.

Long term Sunday night through Friday
issued at 311 am cst Sat nov 18 2017
a fairly tranquil period expected across the region. The only
chances for precipitation are Tuesday into Tuesday night across
the far north, and then again late next week (Friday).

For Sunday night, mostly clear skies are expected with seasonably
cold temperatures with lows in the teens to middle 20s. On Monday,
much warmer temperatures are expected as the next cold front
approaches from the west. With the lack of snow cover across much
of the area, leaned toward the warmer ECMWF guidance for highs.

The cold front will pass through the area Monday night into
Tuesday morning, bringing blustery or possibly windy conditions
and colder temperatures on Tuesday. Winds do turn to the northwest
for chances of lake effect snow showers across the far north. The
chances will linger through much of Tuesday night, with only a
slight chance of snow showers into Wednesday morning. Wednesday
should see seasonably cold temperatures with warmer temperatures
returning for Thursday and Friday. Friday could end up being very
mild, with temperatures possibly being several degrees warmer than
the current forecast. The next chance of rain snow will be on
Friday into Friday night.

Aviation For 12z TAF issuance
issued at 508 am cst Sat nov 18 2017
areas of drizzle and freezing drizzle will continue early this
morning as a cold front exits the region. Some snow may also be
mixed in at times. Conditions varied widely from lifr across the
north, with some pockets ofVFR across the south. Conditions are
expected to settle in the MVFR ifr range later today, eventually
rising toVFR late this afternoon and early this evening. Drier
weather is expected as the day progresses, however some lake
effect will be noted across the far north later this afternoon and
into the overnight hours.

Marine
Issued at 311 am cst Sat nov 18 2017
north winds will increase behind a departing cold front today then
turn northwest tonight. A few gale force gusts are possible
through this evening before winds slowly diminish later tonight.

Given the brief nature of the gale force winds, will continue with
a small craft advisory for the nearshore waters through Sunday
when winds are expected to die down below criteria.

Grb watches warnings advisories
None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
