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.

Short term (tonight through Tuesday)
issued at 215 pm cdt Mon may 29 2017
scattered showers and isolated storms moving east southeast across
the region this afternoon. Upper level shortwave trough, cold air
aloft-decent low level lapse rates, and a bit of instability
providing the lift for the pcpn. With much of it diurnally driven,
expect the activity to weaken diminish with sunset - and
should be done before midnight.
Closed 500 mb low trough wobbling slowly across the region southern
canada, gradually slated to lift northeast of the region Wed night.
Cold air advection continues in the low levels, with various bits of
upper level energy rotating through the trough. Coupled with
favorable low level lapse rates and weak (mostly afternoon)
instability 200-500 j kg MUCAPE and scattered showers will persist
into Tue evening. Isolated storms possible, Tue afternoon - moreso
for parts of northeast ia southwest wi.
Expect another relatively cool day Tue with the clouds and showers
lending a hand in holding highs well below the late may normals.
Upper 50s to mid 60s expected.
Long term (Wednesday through Monday)
issued at 215 pm cdt Mon may 29 2017
a brief break from the constant shower chances expected for Wed into
thu as both the GFS and ec continue to paint a sfc high across the
upper mississippi river valley. Both then want to lift a west-east
running warm front northward across the local forecast area thu
night. This boundary could sit there into Saturday morning,
providing a good focus for shower storm development - with moisture
transport low level jet and bits of upper level energy also working
on the front. See some potential for training storms and heavy rain,
but its too early to discern the extent and any flooding potential.
Something to watch though.
By next weekend some suggestion for some shortwave ridging a loft,
with a sfc high meandering in from southern canada. A couple more
dry days could be the result. That said, latest 12z ec backtracks on
that - sliding another shortwave across the region. Pretty good
chance for showers storms in this latest rendition. Considering the
model inconsistency and disagreements, will let the model blend
dictate rain chances in this period.
After a cool start to the week, temps look to rebound to something
close to the early june normals.
Aviation (for the 18z tafs through 18z Tuesday afternoon)
issued at 1204 pm cdt Mon may 29 2017
a large trough of low pressure will remain over the region and
impact the krst klse airports through Tuesday. Plan on the scattered
showers and breezy west wind to diminish after sunset withVFR
conditions prevailing. More showers are expected during the daytime
heating Tuesday with cloud bases hovering between MVFRVFR.
Otherwise, visibility in showers are expected to remainVFR. Look
for northwest winds to become gusty again by mid-morning Tuesday.
Issued at 331 am cdt Mon may 29 2017
a flood warning continues along the mississippi river at both
mcgregor and guttenberg dam 10. Meanwhile elevated river levels
continue along the mississippi river north of mcgregor. If you are
planning any recreational activities on the mississippi river be
alert for these high water levels and watch out for debris in the
water that may pose a threat to watercraft.

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.
