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.

no significant changes from the previous forecast regarding the
winter storm that will bring heavy snow and wind late Saturday and
Sunday. Confidence remains high in a narrow strip of heavy snow from
southeast minnesota though north central wisconsin. Confidence
remains very high that northwest will increase Saturday night, with
gusts near 50 mph possible across the open areas of minnesota, and
gust near 40 mph possible elsewhere. Confidence remains high that
cold air advection will lead to falling temperatures on Sunday, with
overnight lows going below zero and Monday morning wind chills of 25
to 35 below zero. In summary, confidence is high in significant
impacts from this winter storm.
As for the forecast details, the NAM has come into better agreement
with the GFS gem ECMWF in terms of low strength and placement. It's
mass fields are the #2 analog match with the february 20,21 2014
blizzard. Several sites reported wind gusts over 50 mph with that
storm, and most roads ended up being closed across the south central
minnesota. The main difference this storm is a bit farther east, so
shift the heavy snow band from that event eastward, and you should
have a pretty good proxy of the expected impacts from this storm.
There is a high likelihood of road closures Saturday night into
Sunday for locations that are under a blizzard warning. The snowpack
is deep, should be blowable, and forecast soundings show several
hours with 45-50 kts of wind at the top of the channel. The long
duration of winds should lead to widespread drifting across roads,
along with areas of whiteout conditions.
Hires models show the heaviest swath of snow remaining southeast of
the twin cities, along a line from albert lea through red wing
minnesota and ladysmith wisconsin. Have expanded the blizzard
warning a few counties to the east where we should see strong winds
along with heavy snow. It is unusual to get blizzard conditions
in wisconsin, but the strength and rapid intensification of this
storm is equally unusual. Meanwhile, have also expanded the winter
storm watch a bit north from the current warning. There potential
for winter- storm like impacts with less than 6 inches of snow is
sufficient to support a watch. Would like to see a few more hires
model solutions come in to get a better handle on the
precipitation. Bottom line is there is too much uncertainty to go
with a winter storm or blizzard warning, but there is also to much
potential given the deep snowpack and wind forecast to limit this
event into a winter weather advisory.
Long term (Sunday night through Friday)

next week will continue to have a chance of precipitation in the
form of snow. However, these systems next week do not look as potent
or impactful, especially considering the cold arctic air mass
overhead, and the lack of deep moisture. The jet stream will be a
fast zonal flow with occasional short waves interacting with this
jet, and mid-level forcing. This will occasionally generate some
light snow. However, it doesn't look as impactful in terms of heavy
The unseasonably cold temperatures will continue next week, and into
the first part of march. Model ensembles and anomalies of 925mb, and
850mb temperatures are nearly 2 to 3 standard deviations below
normal across the upper midwest next week. It is even colder with
standard deviations in the 3 to 5 below normal along the front range
of the rockies, and into parts of the northern plains. Thus, i
wouldn't be surprised to see record lows next week, and into next|
weekend. The normal highs for late february and early march are in
the low to mid 30s and overnight lows near 20.

one last batch of light snow moving across east central minnesota,
and into west central wisconsin over the next few hours.
Otherwise, lifr ifr CIGS develop across southern minnesota and
likely expand north and east during the morning. There remains a
small chance of freezing drizzle this morning in far
southern southeast minnesota, and into west central wisconsin.
However, confidence for a period of significant freezing drizzle
is low. It looks as though it will be fog mist at best with
vsbys CIGS lowering to lifr. The next chance of light snow
develops late this afternoon in far south central southeast
minnesota, and moves northeast. Blowing snow will develop tonight,
with vsbys lower to lifr.
left out freezing drizzle this morning. Confidence is very low any
significant freezing precipitation develops this morning once the
snow ends. It should be mainly fog mist with CIGS lowering to
lifr ifr, and lasting through the day. Light snow blowing snow
will develop during the late afternoon, and evening, with gusts
over 30 kts likely after 6z.

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.
