Short term (through late Sunday afternoon)
issued at 330 am cdt Sat aug 24 2019
surface ridge will remain in place across the region today with
cool and dry easterly flow. However, will continue to see an
increase in mid and high clouds from the west as next system
approaches region. Highs will remain a bit below normal in the upper
70s to around 80 degrees.

By tonight, surface ridge will begin to slide off to the east as
deepening upper level trof slides southeast towards forecast area.

For now just have slight chance pops after 06z Sunday for portions
of central and southeast mo, then slowly increase and spread across
the forecast area with best chances along and south of i-70. Low
level moisture will be in the increase but still some uncertainty on
how much moisture will return as surface flow will remain east to
southeast, so just kept chance pops for now.

Cool conditions tonight with lows in the upper 50s to low 60s. Highs
on Sunday will remain a bit below normal in the mid 70s to around 80
degrees.

Long term (Sunday night through Friday)
issued at 330 am cdt Sat aug 24 2019
as upper level trof exits forecast area Sunday night, precipitation
chances will taper off from northwest to southeast.

On Monday, main long wave trough is still progged to slide through
dragging a cold front across the region. Will have increasing
chances of showers and storms, especially Monday night. As cold
front exits region, precipitation will taper off during the day on
Tuesday. Surface ridge builds in for the last part of the work week
with several upper level shortwaves sliding across the great lakes
region, but with limited moisture and surface ridge overhead, dry
and cooler weather expected, though could see some showers and
isolated storms Thursday night through Friday morning.

Aviation (for the 18z tafs through 18z Sunday afternoon)
issued at 1240 pm cdt Sat aug 24 2019
vfr flight conditions are expected this afternoon into this
evening with this afternoon marked by diurnal CU and thin cirrus
and occasionally gusty easterly winds. Clouds and moisture will
increase across the area overnight and into Sunday morning. This
will result in gradually lowering cloud bases with MVFR flight
conditions into kcou by mid morning on Sunday. There will also be
isolated-scattered showers across the area and maybe a rumble of
thunder at some point. At this time I have left the terminals dry
due to uncertainties and lack of pops in the current forecast.

This will be evaluated further in subsequent forecasts.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
