Short term (this evening through Wednesday)
issued at 257 pm cst Tue jan 23 2018
abundant low-level moisture has allowed low stratus clouds to keep
much of the area from seeing Sun today. South central south dakota
is only retaining high clouds this afternoon, associated with a
quick-moving, weak upper level trough. Despite brief clearing, many
can expect partly to mostly cloudy skies through the evening and
overnight hours, since lingering low-level moisture should allow low
clouds and areas of fog to re-form, primarily between the james river
valley in the west and the buffalo ridge in the east.

Temperature-wise, seasonal readings today give way to warmer than
average conditions tomorrow (Wednesday), as an upper-level ridge
builds over the plains. Highs will be in the 30s, with light south
winds.

Long term (Wednesday night through Tuesday)
issued at 257 pm cst Tue jan 23 2018
dry and relatively quiet weather is expected through the forecast
period (through early next week).

The upper-level ridge and associated high pressure to the southeast
of the region will allow relatively warm south winds 10 to 15 mph to
continue through Thursday. The upper level ridge then moves east
Friday, with a trough moving in. Most of the energy and
precipitation with this next system will be well north along the
canadian border, meaning that a subtle increase in clouds and a
shift to west winds will be the primary sensible weather change for
the tri-state area. Saturday's temperatures remain mild and slightly
above normal, with light west winds continuing.

By Sunday, a cool canadian airmass will push south through the
region as the upper level jet stream becomes northwesterly. Although
confidence is very low this far out, light snow could be possible
with this weak cold front. Sunday into Monday morning looks to be
the coolest period of the next 7 days, although temperatures during
this period are only slightly below average. Early next week,
another ridge looks to build, which would again bring a change to
warmer southerly winds.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 452 pm cst Tue jan 23 2018
light and variable winds overnight with MVFR ifr ceilings. Could
also have areas of MVFR fog develop after 04z. Conditions will
improve by late morning on Wednesday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
