Update
Issued at 605 pm cdt Fri aug 23 2019
updated to include 00z aviation discussion below.

Short term (this evening through Saturday night)
issued at 215 pm cdt Fri aug 23 2019
little change in pattern through Saturday night. Highs pressure
will remain in control keeping area dry and slightly below
normal temperature wise.

Another cool night with light winds and clearing sky. Should see
lows tonight drop into the upper 40s far east and 50s generally
elsewhere.

High pressure will retreat slowly over the northeast CONUS by
Sunday morning. Southeast winds will increase over the west
Saturday ahead of the incoming upper trough and pressure falls.

Expect more diurnal cumulus much of the area Saturday but
shouldn't limit afternoon highs warming through the mid upper 70s.

Still most deterministic models trending slower with incoming
dakotas trough. Will hold onto a slight chance pop far west
central CWA after 09z Sunday.

Long term (Sunday through Friday)
issued at 215 pm cdt Fri aug 23 2019
the overall focus in the extended forecast continues on mainly the
Sunday night thru Monday timeframe for fairly widespread rain
across the area while temperatures start out near normal in the
first half of the week then drop to below climatological norms in
the latter half.

To start out Sunday, high pressure will be centered over new
england, underneath a definitive upper level ridge over the
northeast conus. A weaving cold front will extend southwest from
hudson bay into northeastern mt into northwestern wy. A pair of
identifiable low pressure centers over the western dakotas will
merge over the weekend, aiding the cold frontogenesis. An upper
level trough will continue to lumber its way eastward Sunday night
into Monday, sitting atop the upper mississippi river by daybreak
Monday. The cold front will trail the upper level feature a bit,
moving into western mn early Monday. Deep moisture will accompany
these surface and upper features, some from the pacific with the
trough and some from the deep south in the low-to-mid levels in
advance of the systems. This will all contribute to the
development of fairly widespread showers with some thunderstorms
spreading east across mn wi mainly Sunday night through most of
Monday. Sufficient dynamics along with the steady progression of
this system should allow QPF to easily reach 1-2" for much of the
wfo mpx coverage area during this event.

This cold front will move into wi late Monday then across the
great lakes Monday night into Tuesday, away from the coverage
area and bringing an end to the main rain threat of the extended
forecast. A secondary cold front looks to drop south through mn wi
during the middle of next week but this front will be rather
progressive, have much less moisture available and not have any
impressive upper level support for much in the way of
precipitation.

That being said, the cold front for next week does look to bring
in noticeable cold air advection with is passage. This means
that below normal temperatures will very likely be realized for
the latter half of next week.

Aviation (for the 00z tafs through 00z Saturday evening)
issued at 605 pm cdt Fri aug 23 2019
another quiet forecast period withVFR conditions is expected as
high pressure continues to slowly move east of the region. Return
flow on the backside of the high will increase on Saturday, but
temperature advection will remain neutral, so there won't be much
if any increase in mid high clouds.

Kmsp... No concerns.

Outlook for kmsp
Saturday overnight...VFR. Southeast wind 5 to 10 kt.

Sunday...VFR. Southeast wind 10 to 20 kt.

Sunday night... MVFR possible with a chance of showers and
thunderstorms. Southeast wind 10 to 15 kt.

Monday... MVFR possible with a chance of showers and thunderstorms.

South wind 5 to 15 kt becoming southwest.

Monday night... Brief MVFR possible. West wind 10 to 15 kt.

Tuesday...VFR. West wind 15 to 25 kt.

Mpx watches warnings advisories
Wi... None.

Mn... None.

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.
