Short term (today through Friday)
issued at 349 am cdt Thu aug 22 2019
another benign weather day is expected as canadian high pressure
dominates the region. There will be some mid-level cumulus cloud
cover as cyclonic flow lingers, primarily from central mn across
west central wi.

Temperatures will be akin to early to mid september normals today
and Friday, with highs in the mid 70s and lows in the upper 40s to
lower 50s. Winds will be light given the presence of surface high
pressure.

Long term (Friday night through Wednesday)
issued at 349 am cdt Thu aug 22 2019
little change was made to the forecast for the long term period as
guidance remained consistent with holding off the best chance for
widespread of precipitation until Sunday night through Monday.

This will be followed by a cold frontal passage and temperatures
below normal to finish the month of august.

By Friday night, the surface high will be centered over the
northern great lakes with the upper level ridge over us.

Meanwhile, the western CONUS trough will be in the process of
beginning to dig as a strong jet streak pushes ashore across the
pacific northwest. The trough will continue to dig southeast
across the dakotas Saturday, making slow progress eastward thanks
to the stubborn downstream ridge and surface high. Southerly winds
will increase Saturday, especially across western mn as the
gradient tightens between the departing high and approaching
trough.

The upper jet will push the shortwave into minnesota mainly Sunday
but there are still some timing uncertainties given model
differences at this time. Showers and thunderstorms are likely
Sunday night as the wave moves through and ahead of an approaching
cold front. CAPE and shear parameters indicate a low severe
weather threat, but could foresee a couple isolated strong to
severe storms. Pwats increasing to near 2.0" would also suggest
potential for heavy rainfall, but the front will be rather
progressive, keeping storms moving out ahead of it.

One of the other main differences in the model guidance is the
handling of the surface reflection of the upper trough, especially
given the merger of a pre-existing shortwave initially out ahead
of the quicker moving trough with stronger jet support. Regardless
of the precise differences, a strengthening surface low will
likely drift east across far southern canada early next week, with
a cold front draped south across the upper midwest. At this time
the front looks to move west to east across mn wi on Monday. This
low will move very slowly across northern ontario middle of next
week as it deepens rapidly at this point. What this means for us
is a fairly strong push of below normal temperatures and dew
points in from our northwest and given the very slow movement of
the system to our north, this cool flow could persist for several
days as we finish the month of august.

sct-bkn cumulus over mainly eastern areas this afternoon. Looks to
range 4-6k ft. Earlier 6-7k ft deck evaporated during the morning
as the upper trough swung southeast. May yet see a few sprinkles
in west central wi near keau, but still believe sites will
remain dry.VFR trend mainly skc. Generally light n-ne wind this
afternoon becoming e-se later tonight into Friday morning.

Kmsp... No concerns.

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.
