Update
Issued at 838 pm cdt Fri may 24 2019
watching thunderstorms percolating to the west and southwest of
the forecast area this evening. Made some adjustments to try an
provide better coverage of thunderstorms and which areas they will
affect tonight. Rest of the forecast in the ballpark.

Short term (this evening through Saturday)
issued at 336 pm cdt Fri may 24 2019
an area of low pressure was located over north dakota this
afternoon with an occluded warm front extending southeast across
southern minnesota and eastern iowa. A subtle shortwave trough and
area of cyclonic vorticity advection was supporting rain showers
over northeast minnesota. A few more showers developed over the
past few hours from near inl to evm to just north of dlh. The
precipitation will continue to rotate northeastward around the low
through this evening. Another round of showers may move in from
the west as storms develop in southern north dakota and northern
south dakota and then advance east-northeastward into our western
areas. The area of low pressure will lift into northwest ontario
by sunrise Saturday morning. Skies will remain mostly cloudy
overnight and precipitation chances will diminish. Cyclonic flow
aloft and weak cool air advection should support isolated showers
across our northern zones Saturday with drier conditions to arrive
Saturday night. Clouds will part over the southern forecast area
and will allow the late may Sun to warm temperatures to the middle
60s to middle 70s from the brainerd lakes across northwest
wisconsin. Upper 50s and low 60s are expected elsewhere.

Long term (Saturday night through Friday)
issued at 336 pm cdt Fri may 24 2019
the wet weather pattern continues through much of the long term
with periodic chances of showers and thunderstorms. Other than
Monday, it looks like temperatures will be near normal for this
time of year.

A ridge will build from the central plains into the upper
mississippi river valley on Sunday, while a trough digs
southeastward across central canada. Much of the northland will
see mostly sunny skies with high in control. The only exception
will be along the international border as a backdoor cold front
moves in. This will bring increasing cloud cover and a chance of
scattered rain showers. High temperatures range from the upper 50s
immediately adjacent to the lake superior shoreline to the low to
mid 70s inland.

A shortwave will lift across the central plains on Monday into
the upper mississippi river valley. This will develop a surface
low across the high plains. The low and associated warm front will
lift northeastward into southern minnesota and western wisconsin.

This will spread rain showers into the region. As the surface low
deepens and the high moves off to the east winds will increase
across western lake superior out of the northeast. This will
advect cooler air into further inland bringing cooler conditions
to locations near lake superior with highs in the 50s, while
further inland readings will be in the low to mid 60s. A brief dry
period is possible late on Monday into early Tuesday as a weak
high builds in. However, showers and thunderstorm chances return
to the forecast as a trough lifts from the intermountain west into
the high plains and upper mississippi river valley on Tuesday.

There are run to run and model to model differences with the track
and timing of the system moving in. Looks like showers and
thunderstorms will become increasingly likely as the surface low
moves into the region.

Models vary quite a bit after Tuesday with the potential for more
storms on Wednesday as a shortwave digs in from canada. The ecwmf
and gem guidance aren't as robust with this wave, thus have
little if any precipitation expected. Kept a general consensus of
models at this point due to the differences. Drier weather
expected on Thursday as high pressure builds in from the west.

Aviation (for the 00z tafs through 00z Saturday evening)
issued at 627 pm cdt Fri may 24 2019
widespread MVFR ifr with isold lifr CIGS vsbys at the start of
this forecast. Brd should improve toVFR by 02z as an area of
clearing spreads in. Additional cumulus cloud formation is
occurring with the clearing. Spotty showers will be in the
vicinity of most of the terminals through the evening. Trends are
for a few thunderstorms to approach inl towards 06z, but will
leave out for now as confidence is low, will continue to monitor
however for late inclusion. A gradual improvement in CIGS vsbys
will occur overnight. Llws is expected at hib dlh hyr tonight with
a low level jet passing nearby. Areas of br fg are also forecast
through the overnight with improvement in the morning as the
surface wind turns west and becomes gusty.

Marine
Issued at 340 pm cdt Fri may 24 2019
northeasterly winds will gradually decrease late this afternoon
into the evening along with resultant waves as low pressure lifts
across northwest minnesota into ontario. Hazardous conditions for
small craft are still expected into this evening, but improving to
below small craft advisory limits after 7 pm. Winds will shift
from the northeast to a southwesterly direction by early Saturday
morning and increase through the day. Expect wind speeds on
Saturday at or below 15 knots. The next opportunity for strong
winds will later on Sunday into Monday evening as another low
moves toward the region.

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.
