Short term (through late Sunday afternoon)
issued at 307 pm cdt Sat sep 23 2017
early this afternoon, an upper level ridge remains dominant over our
region. Under this ridge, a couple "airmass" showers have developed
but have also been very short lived. A large surface high pressure
is centered over the eastern great lakes, a bit further north than
24hrs ago, and has resulted in a more easterly flow over our region
versus southerly like it was yesterday. This more easterly flow has
resulted in temps a deg or two cooler than 24hrs ago. A healthy
diurnal cumulus cloud field was over much of our region. As of this
writing, no record temps have been tied.

Some "airmass" showers or storms could still develop thru sunset,
particularly in northeast, central, or southeast mo. Otherwise,
look for the diurnal cumulus cloud field to dissipate around sunset
with clear skies overnight. Persistence will be hard to beat for
min temps overnight, with mid to upper 60s for most areas, and
low 70s for urbanized areas of stl metro.

The upper ridge's influence looks to finally weaken on Sunday as it
moves away further to the east, with the models even showing a weak
upper level disturbance rotating around the ridge into southern il
by Sunday afternoon. Already have low pops going for southeast and
central mo again but this may need to be expanded in coverage in
subsequent forecast packages.

With the departure of the upper ridge, MAX temps should continue to
take more of a hit and edged them down another deg or two from
persistence.

Long term (Sunday night through next Saturday)
issued at 307 pm cdt Sat sep 23 2017
a very amplified upper air pattern will begin the work week with a
deep trough of low pressure across the rockies and a strong ridge of
high pressure across the northeast conus. Deep south southwesterly
flow overhead will ensure unseasonably warm temperatures continuing
until the passage of a cold front Tuesday afternoon.

Trof of low pressure attempts to push east by midweek but really
gets shunted to the north into the upper midwest with the overall
flow becoming more zonal across the center of the conus. The
accompanying surface cold front is still expected to move through
the cwa, but with the best dynamics staying well north and limited
low level moisture, pops continue to slowly dissapear in the
extended. At least the front should knock temperatures back to
normal with highs in the 70s.

Aviation (for the 18z tafs through 18z Sunday afternoon)
issued at 1242 pm cdt Sat sep 23 2017
vfr conditions and light southeasterly surface winds will prevail
at the TAF sites thru the valid period. Patchy fog may once again
briefly impact sus and cps, but will wait a few more hours before
including, to see realized crossover temps. Isolated tsra shra
anticipated to form in central and southeast mo but probs too low
for TAF mention at this time but will bear watching. A similar
setup expected for Sunday afternoon.

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.
