Short term (today and tonight)
issued at 401 am cdt Fri may 24 2019
showers and isolated thunderstorms continue to lift across the area
very early this morning - this in association with midlevel theta e
advection overspreading the region out ahead of upper level energy
tracking through western sd. This activity will continue to lift to
the north and east through the morning - exiting our area by late
morning, with clearing skies in the afternoon. A much warmer day in
store as a warm front lifts to the north, resulting in a
southwesterly low level flow by afternoon. This will bring highs
into the mid to upper 70s across the area. With decent mixing and ml
winds averaging 15 to 30 kts, it will also be a breezy afternoon.

Tonight will have mostly clear skies as a surface ridge begins to
build southward into the area. Lows will run in the upper 40s to
lower 50s.

Long term (Saturday through Thursday)
issued at 401 am cdt Fri may 24 2019
a cool front will slide through our area on Saturday, stalling just
to the south of our CWA by Saturday evening. It will have only minor
effects of temperatures however, with highs still climbing into the
70s. Surface high pressure drifts across the region on Saturday
night and Sunday, keeping it dry, and with winds veering to
southeasterly on Sunday on the backside of the high, temperatures
will climb a couple of degrees over Saturday - mid to upper 70s.

Shower and thunderstorm chances will return by Sunday night and
Monday as low pressure deepens over western nebraska and lifts
northward through the period. Cannot rule out a stronger storm over
south central sd on Sunday evening where shear and instability is
optimized. A secondary risk of stronger storms exist on Monday
afternoon over northwestern ia with a warm front lifting into the
area in association with the previously mentioned low pressure. It
will remain warm on Monday with highs again in the 70s.

The system slowly pulls away on Tuesday, allowing for cooler air to
drift into the region, with temperatures mostly 60s for Tuesday and
Wednesday. Shower and isolated thunderstorm chances remain into
early on Wednesday as an upper level low slides across the northern
plains.

Below normal temperatures linger into Thursday with a
northwesterly upper level flow remaining over the region, then
possible warming by Friday as a more zonal upper level flow develops.

Aviation (for the 12z tafs through 12z Saturday morning)
issued at 557 am cdt Fri may 24 2019
showers and isolated thunderstorms will end by mid morning, with a
brief period of drizzle possible after the rain ends. Ifr
ceilings will improve by late morning. Southwesterly winds will
pick up in the afternoon, gusting 20 to 30 kts at times into early
evening.

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.
