Marine Weather and Tides
Finlayson, MN

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Update
Issued at 635 pm cdt Wed jun 20 2018
updated aviation section below for 00z TAF taf issuance.

Short term (this evening through Thursday)
issued at 354 pm cdt Wed jun 20 2018
a broad area of high pressure builds over the great lakes today into
tomorrow resulting in mainly sunny skies and mild temperatures. A
low chance for a stray shower across parts of the boundary waters
canoe area and gunflint trail region late today but otherwise the
diurnally-driven clouds will clear out and make way for a
spectacular evening across the northland. A late-day lake breeze
will move inland from lake superior but otherwise winds becoming
calm overnight with lows in the 50s, as cool as the mid upper 40s
near lake superior and especially across lower elevations along the
south shore. A low chance for some patchy fog across these lower
elevations as well - mainly northern parts of douglas, bayfield, and
ashland county.

A strong lake breeze develops on Thursday due the area of high
pressure becoming centered over the upper great lakes. Highs as warm
as the mid to upper 80s in north-central minnesota, but along the
lakeshore and well inland from the lake highs will be in the 60s
to low 70s. East to northeast winds will increase to 10 to 15 mph
off the lake.

Long term (Thursday night through Wednesday)
issued at 354 pm cdt Wed jun 20 2018
the extended period will be dominated by a very broad upper level
trough that will cover almost the entire nation. Much farther to the
north will be the closed hudson bay low. This will put the northland
under a very weak upper level flow, which means a fairly stable
period. A weak and shallow cold front will move south across the
region on Saturday which could set off some showers. Then it will be
back into high pressure until mid week when a much strong low
pressure area advances from the southwest.

Aviation (for the 00z tafs through 00z Thursday evening)
issued at 635 pm cdt Wed jun 20 2018
another quiet period expected with a ridge of high pressure over
the area andVFR conditions. Winds to stay less than 10 kts for
all but dlh, where a lake breeze will push winds to around 10 kts
after 18z.

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.
