306 am cdt Sun may 26 2019

Short term
Today and tonight - confidence... Medium
drier air working in behind frontal boundary. This trend will
continue today with dew points dropping into the upper 40s to
lower 50s. Surface high will bring subsidence to the area as well
with focus for precipitation to our south. Will have CWA dry with
perhaps just a very slight chance in our extreme south for a time
this morning. Overnight the high will largely dominate with the
potential for some showers nudging into the far southwest portion
of the CWA late in the night.

Long term
Monday and Monday night... Forecast confidence low to moderate...

by daybreak Monday morning, convection should be ongoing to our
west within a broad zone of low and mid level warm air advection.

This activity should propagate east with time, as the 850 mb
frontal zone and associated lift pushes into the forecast area.

While the elevated front will lift through the area, guidance
generally keeps the surface front around the state line through
the day Monday. There will be a conditional threat for severe
thunderstorms Monday if enough clearing heating is able to take
place to generate sufficient surface based instability within the
vicinity of the surface front. Hail, wind, and a tornado or two
would be possible with this activity, given storm motions parallel
to the warm front. Much of this will be dependent on how
convection evolves to our west earlier in the day, so overall
confidence is low.

Tuesday and Tuesday night... Forecast confidence low...

a bit of shortwave ridging may keep things relatively quiet Tuesday
morning. As the mid level low begins to move into nebraska on
Tuesday afternoon, convection is expected to develop across
southern minnesota and much of iowa. This is then expected to push
into southern wisconsin Tuesday evening into Tuesday night.

Plenty of shear will be in place to sustain convection, with
instability again serving as the wildcard. If the surface warm
front is able to mix north into the forecast area, then surface
based severe thunderstorms will be possible given a considerable
amount of warm sector buoyancy, with an attendant wind, hail, and
tornado risk. On the other hand, should the front remain south,
then convection would be expected to remain elevated, with perhaps
just a few instances of large hail.

Along with the severe weather risk over the next few days, hydro
will also be a concern. Many rivers are already elevated, with
soils saturated in a lot of locations. River flooding will likely
become more widespread as the week GOES on, along with the
potential for some areal and or flash flooding.

Wednesday and Thursday... Forecast confidence moderate...

the upper level low will slowly migrate across the area Wednesday
into Thursday, with a continued chance for showers and a few
thunderstorms. Severe weather looks unlikely at this time given an
increasingly open and positively tilted nature to the low. By
Thursday afternoon, rain may actually end for a short time as
slightly drier air builds in from the northwest.

Friday into next weekend... Forecast confidence low...

overall, the active pattern looks to continue into next weekend,
though extended guidance is in poor agreement with the
particulars on timing and coverage. Temperatures for now look to
be around average for the end of may, with highs in the 70s and
lows in the 50s.

Aviation(09z tafs) Vfr conditions this period. Still some broken
stratocu here and there with cirrus canopy blowing into the area
from convection to our south. As a front works through winds are
shifting to the northwest and will eventually turn onshore today.

High pressure will dominate into tonight with a light wind regime.

Marine A rather light wind regime will be in place today through
tonight as high pressure builds across the area. Northeast to east
winds will pick up a bit for Monday and Monday night but gusts are
proggd to be well below gales and will probably not necessitate a
small craft advisory either for the nearshore waters.

Mkx watches warnings advisories
Wi... None.

Lm... None.

Monday through Saturday... Boxell

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
