Update

update for new 12z aviation discussion below.

Short term (today through Tuesday)
issued at 254 am cdt Mon aug 20 2018
a cold front extended across lake superior through northwest
wisconsin and into western iowa as of early this morning with a
surface low centered along the iowa missouri border. Showers and
thunderstorms were occurring north and west of the front from the
brainerd lakes and aitkin areas northeast into the arrowhead.

These were driven by fgen and a deformation zone. The
showers storms were most widespread in the aitkin brainerd lakes
region and pockets of heavy rain were occurring. The front will
continue east today clearing northwest wisconsin by late afternoon
and there will continue to be a chance for showers storms across
the northland with chances highest over far eastern minnesota and
northwest wisconsin. Much of the guidance agrees that the
widespread showers storms in our southwest zones will diminish
over the next 2 to 4 hours. Cooler temperatures behind the front
along with cloud and rain coverage will lead to lower high
temperatures today. Highs will range from the mid sixties to lower
seventies.

The chance for showers will diminish overnight but linger over
portions of northwest wisconsin into Tuesday morning. High
pressure will build into the region Tuesday and most areas will be
dry by Tuesday afternoon. Highs will range from the upper sixties
to lower seventies.

Long term (Tuesday night through Sunday)
issued at 254 am cdt Mon aug 20 2018
high pressure will move through the region and bring quiet
weather and seasonal temperatures through Thursday. Showers and
thunderstorms return to the picture Thursday night through the
weekend.

A broad ridge of high pressure centered over the dakotas Tuesday
night and will gradually slide southeastward into the lower ohio
river valley by Thursday evening. Upper-level winds are favorable
for western wildfire smoke to return to the northland through
Thursday. The return of smoke may result in air quality concerns
or may merely create hazy skies. Temperatures will trend warmer on
Wednesday, slightly above normal, with highs from the low 70s in
the northeastern arrowhead to the middle and upper 70s elsewhere.

Similar temperatures are expected for Thursday.

A well-organized and vertically stacked trough of low pressure
will move across the northern plains and canadian prairies and
into minnesota and northwest ontario by Friday. There are some
model differences in the details, but each of the long-range
models favor precipitation chances starting Thursday night and
continuing through Friday night or early Saturday. A shortwave
trough is forecast to lift from the central plains into the upper
midwest Saturday night and Sunday with a warm front lifting toward
the northland during the afternoon. Shower and thunderstorm
chances return as the front approaches during the afternoon and
continue through the night. A few of the storms late week through
the weekend may be strong to severe and there is a potential for
locally heavy rain.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 704 am cdt Mon aug 20 2018
an inverted trough of low pressure stretched into the northland
from a surface low over southern iowa this morning. Overcast skies
are expected for much of the day with scattered showers and a few
isolated thunderstorms. With onshore winds near duluth and wind
speeds increasing later this morning into the afternoon, think
we'll see persistent MVFR ceilings at dlh today through tonight.

Patchy fog is possible once again late tonight as skies clear and
radiational cooling develops.

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.
