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.

Short term (this evening through Sunday)
issued at 312 pm cdt Sat may 25 2019
weak cool air advection and cyclonic vorticity advection provided
sufficient instability and lift for widespread cumulus and a few
showers this afternoon. Have isolated showers in the forecast
through 7 pm over much of the northland. The showers and clouds
should begin to dissipate an hour or two before sunset, but think
a few may linger until nearly 10 pm. High pressure drifts eastward
through the region tonight and Sunday while a weak cool front is
forecast to sag southward into the northland Sunday afternoon.
Lows tonight will be in the upper 30s and low 40s. Mainly cloudy
skies are expected Sunday near the front. A few rain showers may
develop and affect the international border area during the day.
Highs will reach the middle 60s north and the middle 70s south.
The front will stall over northern minnesota and lake superior
Sunday night. Convergence along the front will receive a boost
from increased southeasterly flow around the northeast periphery
of an approaching area of low pressure late Sunday night. The
chance of showers will spread farther south and affect most of the
northland by early Monday morning.
Long term (Sunday night through Saturday)
issued at 312 pm cdt Sat may 25 2019
the main weather maker in the extended period will be a system
sliding through southern wisconsin on Monday night. This system is
modeled fairly well, but there are discrepancies in the amount of
water contained in the system with the NAM being moist with pw's
in excess of 1.25" while the GFS is struggling to eclipse 1.0".
Best dynamics are to our south, but some wrap around precip on the
northern tier may clip our NW wi counties. The SREF probabilities
of precip are bringing the potential for moderate rainfall all
the way up to lake superior. Most models have some signal of
precip over NW wi, so upped the pops there over model consensus by
about 25%. Similarly increased the QPF given the relatively high
moisture content of the atmosphere.
The GFS and euro largely kick this system out of the area by
Tuesday; however, the NAM and canadian and even the SREF ensembles|
indicate some lingering potential for precip, so again upped the
pops particularly since the NAM has been one of the better models
as of lately with this cold spring pattern.
Another system crosses Wednesday, but will likely be a similar
track and intensity to Monday evening's system. High pressure
builds afterwards as an upper level trough slides near southern
ontario for the start of june with cooler weather expected.
Aviation (for the 00z tafs through 00z Sunday evening)
issued at 639 pm cdt Sat may 25 2019
a broken deck of cumulus clouds around 6k ft covered the terminals
at the start of this forecast. TheseVFR clouds will dissipate
around 02z leaving a mainly clear sky. Some showers will be in the
vicinity of hib until 02z, then subside. Some patchy br is
possible near brd around 11z, but should quickly erode by 13z. A
cold front north of the international border will drift toward
inl after 14z and bring some MVFR clouds to the terminal, with
improvement back toVFR by 21z.
Issued at 931 pm cdt Sat may 25 2019
high pressure builds over the waters with mostly quiet
conditions. A few stronger systems will move through southern
wisconsin through the upcoming week, but should only slightly
increase the winds across the waters.

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.
