Short term (this evening through Sunday)
issued at 256 pm cdt Sat jul 21 2018
morning fog and low stratus has slowly but gradually started mixed
out through the early afternoon hours, resulting in a perfect
Saturday afternoon by late july standards. On a large scale, the
region continues to sit in a northwesterly flow aloft regime in
between a large cut-off low to our east and building ridge to the
west. This will allow for continued quiet weather and light winds
into the overnight hours.

Thunderstorms are expected to develop this evening and overnight
well to our west across the high plains ahead of an incoming wave
and push of warm advection. These storms will try and move east but
will very quickly out run their instability by around the mo river.

Cams support this idea of any precip activity rapidly fading by the
time it reaches our coverage area and thus will only carry slight
chance pops west of the james river for early Sunday. Temperatures
will run similar to Saturday, perhaps a degree or two higher, or
generally in the upper 70s to mid 80s. Look for a mix of Sun and
clouds as relatively light winds could again lead to some patchy fog
or lower clouds Sunday morning, in addition to the leftover mid and
upper level debris from overnight convection.

Long term (Sunday night through Saturday)
issued at 256 pm cdt Sat jul 21 2018
by Sunday night and early Monday, a jet streak sneaks by to our
north with a cold front trailing southward through our area. This
should be enough forcing to spark renewed thunderstorm activity with
the initial development to the west of our cwa. While storms near
and west of the mo river have the potential to be strong,
instability becomes fairly meager as one moves east, again likely
leading to decaying or at least weakening activity by the time it
moves toward the i-29 corridor. This is further supported in the
day 2 marginal outlook from SPC covering areas west of the james
river.

Another wave and associated front passes around the Tuesday night
and Wednesday time frame and could bring another chance of showers
and storms. Models diverge some by mid week with the placement of
the boundary(s) but agree on an active jet overhead. For this
reason, occasional precip chances may continue thru the rest of
the work week, although no one particular day emerges as being
overly impressive or having a higher confidence.

Temperatures through the entire period remain somewhat steady,
generally fluctuating between the mid 70s and mid 80s for afternoon
highs and mid 50s to mid 60s for overnight lows.

Aviation (for the 00z tafs through 00z Sunday evening)
issued at 603 pm cdt Sat jul 21 2018
diurnal CU field will quickly dissipate this evening, leaving
continueVFR conditions into the overnight hours. Again, concerns
about fog and potential stratus development by Sunday morning.

There should be a gradual increase in mid-level clouds and a bit
more of a mixy boundary layer to prevent dense fog. That said,
will monitor trends this evening.

Can't rule out a few showers impacting hon by morning, with mid-
level clouds spreading eastward during the day.

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.
