Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.

updated aviation portion for 00z TAF issuance
Short term Tonight and Monday
issued at 328 pm cst Sun feb 17 2019
snow continued across about the southern half of wisconsin today
but was not making a great deal of northward progress. The dry
air between 890 mb and 630 mb, as seen on the 12z kgrb sounding,
is likely a major factor in keeping much of the snow out of the
area. There was a band of lake-effect snow that passed through
door county and marinette before continuing to south-southwest
through the green bay area. Lake enhancement in the east is a
concern this evening before the snow departs as the surface low
continues to move away from wisconsin and the mid level trough
axis passes to our east. Manitowoc county appears to have the best
chance to receive accumulating snow but totals are not expected
to be more than an inch or two there.
Clouds tonight should keep temperatures from going into free-fall
so have mainly single digits to around 15 degrees for lows. Some
locations in far north-central wisconsin may end up with lows a
few degrees below zero. A slightly colder airmass will be in place
on washington's birthday but decreasing clouds should allow for
highs in the teens to lower 20s across most of the forecast area.
Long term Monday night through Sunday
issued at 328 pm cst Sun feb 17 2019
a short wave trough moving from the central rockies
towards the great lakes will produce upper diffluence and low
level warm advection late Tuesday night and Wednesday. The upper
jet is very strong (120 kts at 500mb) even for the winter months,
with the left exit region of it forecast to move across the
forecast area Wednesday.
The best moist low low level moisture stays well to our south|
over the ohio valley, but there is still 2 or 3 g kg of moisture
available which should result in about three to five inches of
snow in most places. A jet this strong will likely produce a
narrow band of heavier snow, but it is difficult to tell where
that will be right now.
Upper flow becomes more zonal Thursday and Friday with mostly dry and
seasonable weather expected. Another weather system is possible next
Saturday and Sunday, but the models are having a hard time with it.
Aviation For 00z TAF issuance
issued at 600 pm cst Sun feb 17 2019
dry northeast flow has prevented the northward progress of light snow
into the forecast area, except from roughly y50-osh, and near the
lake michigan shoreline, where lake-effect was becoming more
organized. Based on recent trends, will continue the mention of
occasional MVFR ceilings and flurries well into the evening, but
back off on snow.
The exception will be near lake michigan and the mtw TAF site,
where cold northeast flow will bring lake-effect until after
midnight. Synoptic enhancement will occur during the early to mid
evening, and could result in periods of moderate snowfall and lifr
flight conditions. The snow will end in east central wi
overnight, and clearing skies should occur regionwide late tonight
into Monday morning.
Gusty northeast winds will diminish and become north later this

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
