Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

showers will move north into the forecast area today
as warm air overruns a warm front well to our south. The best rainfall
should be across central and east central wisconsin. The clouds
and precipitation and winds blowing over lake michigan will hold
temperatures down 5 to 10 degrees below normal.
Elevated thunderstorms are expected during the late afternoon and
evening hours as dewpoints in the teens at 850mb stream northward
from the southern plains. The elevated instability could be enough
to produce a few strong or severe storms with large hail in the
fox valley and lakeshore counties.
The showers will end later tonight as a pacific cold front goes
by. It shouldn't even be called a cold front, as temperatures
Saturday will be higher than today due to abundant sunshine and
downslope west winds. Highs could reach 80f for the first time
this year in some areas.
Long term Saturday night through Thursday
issued at 414 am cdt Fri may 24 2019
forecast concerns continue to revolve around precip potential
through the holiday weekend into the middle of next week. Although
there will be breaks in the precip chances at times, southwest flow
aloft will continue during this period, with the western great lakes
positioned between the beefy sub-tropical ridge over the southeast
conus, and an upper low over hudson bay. The result will be a
continuation of the wet pattern that has been in place over the past
several months. Will take a blend of the GFS nam on Saturday night,
followed by a blend of the gfs ECMWF thereafter.
Saturday night through Sunday night... A cold front will be in the
process of exiting northeast wi early on Saturday evening. The
models project some instability lingering over east-central wi along
the front, but the GFS looks considerably overdone, mostly due to
unrealistically high dewpoints. Still though, ml capes over 500
j kg suggest some potential for a storm along the boundary Saturday|
evening. Ample mid-level dry air will keep storm potential isolated
at best. Weak high pressure then will build into the region later
Saturday night and hang around on Sunday. Temps on Sunday will be
cooler, but with no threat of precip. As energy ejects out of the
southwest CONUS trough, the front will return north on Sunday night.
Rain chances will therefore return to central wi late in the night.
Rest of the forecast... A surge of precip will lift across the area
on Monday with the passage of a warm front. Some elevated
instability will accompany the front, though magnitudes look rather
marginal for severe weather. Forecasting frontal positions becomes
a rather dicey proposition thereafter due to presence of
clouds precip and uncertainty of wind directions. Southwest flow
will remain aloft on Monday night into Tuesday, which will be
favorable for precip at times, though perhaps not quite as
widespread as on Monday. Then a second surge of precip looks
possible on Tuesday night as the southwest CONUS trough ejects
across the great lakes. Because of the uncertainty of instability,
potential for heavy rainfall looks higher than severe weather at
this time. A period of cooler weather is possible in the wake of
the system for middle to end of next week.

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.
