254 am cdt Mon aug 20 2018

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 06z tafs through 06z Monday night)
issued at 1245 am cdt Mon aug 20 2018
a cold front has stalled out over the region and will keep cloud
cover in place through much of the forecast period. CIGS are
generallyVFR but are expected to lower to MVFR as rainfall moves
in. Confidence is low overall on the timing and intensity of
rainfall and any TS activity, so have mainly treated with vc until
things start to look more likely. Some fog has started to form at
kinl and khyr but has not been consistent. This may result in
times of ifr vsbys, but not currently expecting anything lower.

Rainfall will remain possible through all sites aside from kinl
through most of the day Monday, so rainfall chances are in through
about 00z. MainlyVFR conditions should then return for Monday
evening, but some low stratus looks to develop for kdlh and khyr
that may lead to MVFR CIGS for the remainder of the period.

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.
