Short term (this evening through Wednesday)
issued at 237 pm cdt Tue aug 20 2019
scattered thunderstorms have developed this afternoon generally
along and east of the highway 65 corridor. Some of the storms
across central missouri have developed near a remnant outflow
boundary from overnight storms. Storms farther to the south have
developed as convective inhibition weakened with daytime heating.

This activity will continue this afternoon and early evening with
coverage gradually shifting south with time. A marginal risk for
severe storms will continue as the atmosphere will remain
supportive of downburst potential. We will also have to watch the
hydro situation as training storms could pose a localized flash
flooding risk.

Outside of the storms, hot and humid conditions persisted this
afternoon with heat indices ranging from 100 to 110 degrees.

Storms will diminish by mid-evening with the loss of daytime
heating. Another complex of storms will then develop later tonight
across the central plains as a strengthening low level jet
overrides a surface front. This complex of storms is expected to
approach central missouri by around sunrise.

As was the case today, a big concern for Wednesday will be
whether or not that complex of storms affects portions of central
missouri. Current thinking is that most of this activity will miss
the region to the northeast... But not by much. This will
certainly be a short term forecast challenge.

Outflow from that MCS along with an advancing cold front (may be
one in the same) will then provide a focus for scattered afternoon
shower and thunderstorm potential on Wednesday. There will again
be a marginal risk for a strong to severe storm.

One big question for Wednesday will be temperatures (and heat
indices). Confidence has increased that the front outflow will not
make it all that far south into the area during the day. Highs
over most areas should therefore make it into the lower or middle
90s.

It is also quite possible that we see moisture pooling ahead of
the boundary. Thus, heat indices may again push or exceed heat
advisory criteria (105 degrees). We have decided to extend the
heat advisory for south-central missouri as confidence is highest
that heat indices will hit criteria in that region. It is quite
possible that the advisory needs to be expanded to add additional
counties once we get a better feel for the position of that
boundary, as well as expected cloud and thunderstorm coverage.

Long term (Wednesday night through Tuesday)
issued at 237 pm cdt Tue aug 20 2019
that frontal boundary will settle south into the region from
Wednesday night through Friday night or Saturday. We will
therefore see multiple opportunities for showers and
thunderstorms. Some localized pockets of heavy rainfall will be
possible along with a limited risk for strong to severe storms.

Temperatures will also be cooler with highs expected to be in the
lower to middle 80s.

We may then see a brief period of dry weather later this weekend
as the upper level flow becomes weak and benign. Global models
then indicate decent consistency with an increasing west-
northwesterly flow aloft next Monday and Tuesday. This may result
in another frontal boundary moving into the region along with
returning chances for showers and storms. High temperatures should
remain in the middle to perhaps upper 80s.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 631 pm cdt Tue aug 20 2019
a few lingering showers and storms remained across the southern
ozarks this evening but those will continue to diminish in
coverage as they slowly sag south and the heating of the day
tapers off. Cloud cover will be scattered butVFR. Additional
storms will be possible for Wednesday afternoon but coverage and
timing is not certain.

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.
