Short term (today and tonight)
issued at 308 am cdt Mon mar 27 2017
while we'll still be dealing with cloud cover today, it's promising
that most areas will see Sun to start the new work week. Stratus
lingering over the CWA this morning will hold on into the mid-day
hours, but will slowly dissipate through the afternoon. There
remains a few areas where fog has developed this morning as skies
temporarily cleared. Limited coverage however, has not warranted any
advisory at this time.
Mid-level clouds associated with a shortwave moving through the
dakotas early today will linger across the region into the afternoon
hours. With the thinning stratus and a bit more cloud cover,
temperatures should finally climb back into the 50s in most areas.
Light winds and partly cloudy skies persist overnight. Winds will be
quite light once again, but with clouds hanging around, temperatures
may only cool towards the lower to middle 30s.
Long term (Tuesday through Sunday)
issued at 308 am cdt Mon mar 27 2017
the focus in the medium range continues to be on the two slow moving
systems that affect the region mid-week and then again next weekend.
Water vapor shows the first of the two systems currently along the
west coast. This system is expected to deepen and shift east into
the plains on Wednesday. Models have come into better agreement on
the track of this system, and it appears that the forecast area will
be on the northern edge of the precipitation shield. Have kept the
pops fairly high along and south of i-90 with this system, with much
lower pops to the north. With cold core system, expect temperatures
to remain below normal on Wednesday and Thursday. As the
precipitation shifts east on Thursday, will see temperatures start|
to rebound as skies partially clear.
Surface ridge builds into the northern plains Thursday night into
Friday morning ahead of a second large upper level low that works
into the plains over the weekend. This system seems to favor a
slightly more southerly track compared to the first system, making
precipitation far from certain this far north. Still appears as
though this system will try and link with northern stream energy,
but influence of the northern stream wave still seems to be a little
Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 625 am cdt Mon mar 27 2017
MVFR ceilings and areas of fog continue to expand prior to
daybreak. This stratus deck should be fairly thin, but will take
through mid-day to either advect away from fsd/sux or mix out.
Huron should stay on the edge of any lower ceilings.
Clouds should continue to prevail into the evening and overnight
hours, but more mid-upr level variety. Winds remain very light
into Tuesday morning, so it's possible fog could reform. However,
confidence rather low on this event.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
