Marine Weather and Tides
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Update For 06z aviation discussion below
Short term (this evening through Monday)
issued at 340 pm cdt Sun may 28 2017
the main forecast concern is the extent of areal coverage this
evening as most of the shower thunderstorm activity in central
minnesota was diurnally driven. However, a more concentrated area
of showers and embedded thunderstorms that was associated with an
upper level disturbance in northern north dakota, may allow for
the activity to continue through the evening in portions of west
central southwest south central minnesota although weaker than
currently indicated on radar . Still believe that even this
activity will decrease some due to the typical loss of daytime
heating. Will leave a low chance in this area, with most areas in
central southern minnesota, as well as west central wisconsin
having the precipitation ending by 9 pm to midnight.
Tomorrow weather will have more cloud cover and a continued
chance of isolated scattered showers, especially closer to the
upper low which will slowly move from northern minnesota, into
northern wisconsin. Temperatures will reflect the denser cloud
cover with highs only rising into the upper 50s to lower 60s.
Normal high temperatures for late may are in the low to mid 70s.
Long term (Monday night through Sunday)
issued at 340 pm cdt Sun may 28 2017
coverage of the shower activity will begin to decrease Monday
night, and especially Tuesday as the area of low pressure and
instability moves further east of the region. Temperatures on
Tuesday could be similar to Monday as the core of the coldest
air moves overhead.
As with previous forecast discussions, high pressure will build
across the area Tuesday night, and into Wednesday. Once this high
pressure system moves off to the southeast, winds will shift to
the south. This will set the stage for warmer conditions by the
end of the week.
Models have continued to support a warm front near the
iowa minnesota border Thursday afternoon Friday morning. Elevated
instability and a low level jet associated with this front, will|
likely develop an area of showers and thunderstorms, especially in
far southern minnesota. This is also where the higher
precipitation chances remain.
The upper level pattern remains conducive for an upper level ridge
to slowly move eastward across the northern plains by the end of
the week. There remains some model differences past model runs
in the placement and strength of this upper level ridge by this
weekend. Therefore confidence in the forecast past Friday is low,
especially considering the spread in model solutions in terms of
frontal position over the weekend. The best forecast is continue
with low chances of precipitation and hold onto temperatures near
normal with highs in the 70s.
Aviation (for the 06z tafs through 06z Monday night)
issued at 1045 pm cdt Sun may 28 2017
in the wake of the showers we will see winds calm down to around
or below 10 kts overnight. MVFR ceilings will arrive by 09z at
kaxn and expand south and east to the rest of the sites toward
(or shortly after) daybreak. MVFR CIGS then persist through
Monday, with scattered showers developing by 17z. Winds will also
become gusty from the west, with sustained speeds 15-17kts and
gusts to around 25 kts. Monday evening gusts begin to diminish and
scattering of the MVFR deck occurs as well.
vfr conditions are expected until the stratus deck settles in
between 12z and 15z. Scattered showers will then be possible
through the day.
Outlook for kmsp
tue...VFR. Isolated MVFR -shra possible. Wind NW 10-20 kts.
Wed...VFR. Wind NW 5-10 kts.
Thu...VFR. Wind S 5 kts.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
