Update
Issued at 740 pm cdt Sun may 26 2019
bumped up the pops to better represent where rain is already
falling. Made some other minor adjustments.

Short term (this evening through Monday)
issued at 339 pm cdt Sun may 26 2019
a weak cool front was draped from west to east across the
northland this afternoon and is forecast to progress southward
across the remainder of the forecast area this evening. Winds near
lake superior will turn on-shore behind the front and will become
gusty for a time into this evening. Scattered rain showers over
far northern minnesota will continue a gradual easterly trajectory
and a wave of showers over northwest minnesota will lift into the
brainerd lakes by 7 pm. The change of showers continues overnight
with the focus generally over northern minnesota, well north of
the surface front. Convergence aloft and an approaching shortwave
and lobe of vorticity will enhance lift over that area after 06z.

Memorial day is shaping up cloudy, cool, and breezy with chances
of rain showers. Northeast winds off lake superior will bring
lake-cooled air well inland through the i-35 corridor toward lake
mille lacs and the aitkin area. In northwest wisconsin the colder
air will affect areas as far south as danbury, minong, and
hayward. Highs will reach the upper 40s to mid 50s in these areas.

Temps will reach near 60 degrees farther south and a pocket of
upper 50s to low 60s is forecast north of a line from cass lake to
bigfork to kabetogama in north-central minnesota. The rain
chances will be focused across northern minnesota with the passing
shortwave, and over southern zones as a surface low moves across
southern minnesota and central wisconsin.

Surface high pressure returns Monday night and the rain chances
diminish. Temperatures will dip into the middle 30s in the
arrowhead to the low 40s south. A few spots in northern minnesota
may see areas of frost, especially if skies clear faster than
currently indicated.

Long term (Monday night through Sunday)
issued at 339 pm cdt Sun may 26 2019
the long term forecast is not quiet, but it's also not too busy
either. The most headline worthy event is the potential for frost
on Tuesday morning across the mn arrowhead. A fairly large system
crosses south of the forecast area on Wednesday, but the northland
is largely left high and dry - the caveat being if the system
drifted quite a bit north of where it is currently progged to
track. The significant QPF gradient should be down near eau
claire.

A weak trough crosses late in the week for a small threat for
thunderstorms. Location and timing still quite uncertain at this
time on this feature as it's not very pronounced.

Temperatures throughout the week will be quite normal for this
time of the year with highs in the 60s and lows in the 40s.

Aviation (for the 00z tafs through 00z Monday evening)
issued at 646 pm cdt Sun may 26 2019
clouds are increasing in coverage across the terminals with cigs
in theVFR range. Some spotty showers are moving from west to east
and will be in the vicinity of the terminals through the forecast.

Timing is uncertain and will use a vcsh mention, until a
predominate rain arrives in the late afternoon, especially near
hyr, with some br possible. Look for CIGS to drop into the MVFR
range at hyr brd dlh by mid to late Monday morning ahead of the
forecast rain.

Marine
Issued at 740 pm cdt Sun may 26 2019
winds will remain elevated Monday as a low pressure system tracks
across southern wisconsin. Weak high pressure builds Tuesday.

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.
