Short term (this evening through Monday)
issued at 349 pm cdt Sun aug 18 2019
a very nice day has prevailed across the region with light north
winds and temperatures ranging from the upper 60s to upper 70s. This
nice weather is brought to you thanks to the surface high pressure,
currently centered over eastern sd. Winds will begin to transition
to the south this evening into the overnight hours, as the high
moves southeast.

A quiet and chilly night is expected with mostly clear skies and
light winds. Conditions will be favorable for efficient radiational
cooling, thus areas of fog could be possible, mainly east of i-29 by
early Monday morning. Overnight lows will range from the lower 50s
to lower 60s.

Conditions will change to start the work week with the return of
heat and humidity. As the surface high moves east out of the region,
a broad area of warm air advection surges northward into the region.

Precipitation is not anticipated throughout the day, but breezy
south winds from 15 to 25 mph will be possible in the afternoon.

Highs will generally be in the 80s to near 90 along the missouri
river.

Long term (Monday night through Sunday)
issued at 349 pm cdt Sun aug 18 2019
a broad area of theta-e advection moves into the region Monday night
into Tuesday, ahead of a weak upper shortwave. With decent
instability, showers and storms will be possible during this time-
frame. This activity should be hit and miss with no severe weather
expected.

Upper ridge will be centered over the four points southern
plains. Warm and humid conditions continue on Tuesday with highs
slightly warmer than Monday. Highs from the upper 80s to lower 90.

Thunderstorm chances increase across the central plains, ahead of
an upper trough moving north into NE ia. At this time, most of
the precipitation looks possible along and south of the missouri
river valley into highway 20.

The main story Wednesday and beyond is cooler than average
temperatures. Canadian high pressure slides southeast on
Wednesday, bringing drier and cooler air through the end of the
week.

The next chance of precipitation arrives Thursday night through
Friday night as a warm front lifts north into the region. Details at
this point are uncertain. The GFS remains mostly dry while the
ecmwf brings most of the precipitation across the region through
Friday night. As for now, have kept pops as guidance suggests with
a slight chance of precipitation through Saturday.

Aviation (for the 18z tafs through 18z Monday afternoon)
issued at 1235 pm cdt Sun aug 18 2019
a few MVFR ceilings from 2-3 kft are expected to continue through
19-22z Sunday. Otherwise,VFR conditions are expected through the
period.

Patchy fog will be possible early Monday morning, mainly east of
i-29 and along the mo river valley, possibly impacting ksux
terminal.

Light north winds will transition to the south this evening into
the overnight hours.

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.
