Short term (through late Saturday afternoon)
issued at 350 pm cdt Fri aug 23 2019
an elongated low-amplitude disturbance currently tracking in the
vicinity of the mo ia border and attendant mid level frontogenetic
forcing will continue to produce showers and maybe isolated
thunderstorms across southeast mo into early evening. By mid-late
evening the disturbance and forcing should have exited the area.

With the exception of the far south, the remainder of the CWA will
be dominated by an expansive surface high centered within the great
lakes and weak ridge aloft. This will result in a pleasant night for
the later part of august with low humidity and below average
temperatures with lows from the mid 50s to lower 60s.

Saturday continues to look like a great day for this time of year.

The large surface high will continue to exert a strong influence on
sensible weather with "cool" easterly flow and relatively low dew
points. There will be an increase in clouds from the west during the
afternoon ahead of an upper trof advancing through the plains, but
the day looks void of precipitation with a continuation of below
average temperatures.

Long term (Saturday night through next Friday)
issued at 350 pm cdt Fri aug 23 2019
by early Sunday a short wave attached to a larger, robust trough is
moving into the region behind the departing ridge. Models are in
greater alignment for the short wave trough to impact the bi-state
area Sunday into Monday. Moisture increases during the day as the
low level high moves out with the upper ridge and low level flow
turns more southerly. How much moisture will be available while the
short wave trough is providing lift over the area is still
uncertain, and will ultimately determine the coverage of showers and
thunderstorms. As the flow becomes more southerly on Sunday
temperatures will start to rebound but remain slightly below normal.

Lingering precipitation is possible on Monday morning, but depends
on how quickly the short wave trough lifts out of the bi-state area
and potential for any lingering focusing boundaries. The axis of the
longer-wave trough will move through Monday into Tuesday with the
attendant cold front. Showers and thunderstorms will move through
the area Monday night into Tuesday morning and will clear out of the
cwa during the afternoon as a surface high pressure builds in,
promoting clearing.

Disturbances continue to ripple across the upper trough as it tracks
across southern canada through the week. Yet a dry column will
prevent the disturbances from initializing much convection and keep
the area predominantly dry.

Monday continues to be the warmest day of the week as low level flow
brings warmer air from the southern us into our region. In the wake
of the cold front on Tuesday temperatures will steadily cool through
the week, staying below normal.

issued at 618 pm cdt Fri aug 23 2019
skies will clear overnight at the terminals as diurnal cu
diminishes.VFR conditions will persist through TAF period.

Showers are weakening in southern missouri, and lower clouds from
the remnant disturbance will remain south along the boundary. Some
higher clouds may spread north over the terminals this evening,
but will not force category reductions. Saturday will stay dry as
high pressure builds from the northeast in the great lakes region.

Easterly winds will persist through tonight into tomorrow
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.
