Short term (today through Saturday)
issued at 411 am cdt Fri aug 23 2019
the short term period will be dry, so the main focus is the clouds
and winds, especially for Saturday.

High pressure centered over the great lakes will continue to
dominate through Saturday afternoon. Daytime highs and dew points
will be very similar to yesterday given the airmass remains the
same. Like yesterday, mixing my later morning through the afternoon
should yield scattered fair weather cumulus. Highs in the mid to
upper 70s and dew points in the 50s will make for another gorgeous
late summer day.

The high will drift slowly east through tomorrow, but a shortwave
trough will move east from wyoming into the dakotas tomorrow,
enhancing the pressure gradient over mn and wi, leading to
increasing southeasterly winds, especially across western mn. 15 to
20 mph looks reasonable for there, with lower speeds of around 10 to
15 mph for eastern mn and wester wi by Saturday afternoon. High
clouds from storms in the dakotas may spill into western mn by late
Saturday afternoon, but the remainder of the area will be partly
cloud. Very similar temepratures to today are expected for Saturday,
in the mid to upper 70s.

Long term (Saturday night through Thursday)
issued at 411 am cdt Fri aug 23 2019
high pressure holds over the great lakes through the first half of
the weekend, which should keep things dry and pleasant through at
least Saturday night. The main story continues to be the potent
trough passing throughout the upper midwest Sunday through Tuesday,
with widespread showers and thunderstorms expected along a cold
front slowing crossing the region. The slowing trend in this system
has mostly halted with the 00z guidance tonight, with the bulk of
the weekend now looking to stay dry. Some of the quicker solutions
bring precipitation in to western minnesota during the day on
Sunday, but expect the bulk of the precipitation to occur Sunday
night through Monday. Instability does not look to be high enough
ahead of the front to warrant much of a severe weather threat, but
ensemble guidance has pw values rising to the 90th percentile and
the relatively slow motion of the front through the area could lead
to areas of heavy rainfall.

Fall-like weather moves in behind the cold front Tuesday through
Friday as the low becomes cut-off over hudson bay and keeps cool
temperatures aloft over the region. Some cold-air advection showers
look possible Tuesday-Wednesday with weak vorticity aloft, but
precipitation amount should remain light. Temperatures will be quite
cool for august standards with highs in the upper 60s to low 70s,
and lows in the 40s to low 50s.

Aviation (for the 12z tafs through 12z Saturday morning)
issued at 502 am cdt Fri aug 23 2019
vfr conditions will persist through the forecast period with
mostly clear to partly cloudy skies expected. Daytime cumulus will
likely develop, especially in eastern mn and western wi. Southeast
winds will develop later this morning and increase to near 10
knots for most.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
