Short term (today through Wednesday night)
issued at 340 am cdt Mon aug 19 2019
the main concern in the short term is the potential for isolated
to scattered showers and thunderstorms today, primarily across
the northwest half of the area. Then our attention turns to the
potential for better shower and thunderstorm coverage Tuesday and
Wednesday, including some potential for severe weather. The heat
and humidity is another concern. Overall forecast confidence is
decent, but restricted by the typical mesoscale uncertainties.
Unlike the past two mornings, no mesoscale convective systems are
present over the plains early this morning. As a result, we think
the pattern today should be much more subdued compared to over the
weekend. That said, forecast models still indicate some potential
for isolated pulse type thunderstorms in the heat of the afternoon
today. This could occur just about anywhere, but chances appear to
be slightly higher over southeast missouri and southern illinois.
Will cap chances at 30 percent for now.
Most of tonight is looking dry, but Tuesday warrants closer
attention as multiple convection allowing models, including the
hrw (nssl, arw, nmmb), and namnest depict the generation of a
convective complex over iowa tonight, then progress it southeast
into the immediate forecast area by Tuesday afternoon. This is of
particular concern since it's forecast to arrive during the time
of peak heating, with very unstable conditions (sbcapes 4-5kj kg).
Upper level winds are admittedly not that strong, but with such
unstable conditions, it's not going to take much to maintain an
already mature self-sufficient mcs. While confidence is still not
the best, we need to keep a close watch on Tuesday afternoon for
the potential of widespread damaging winds. At this time, the spc
day 2 outlook has much of the area in either a slight or marginal
risk of severe weather. Monitor later forecasts for updates.
As the upper high begins to retreat to the west, energy rotating
around its eastern periphery in northwest flow aloft will set the
stage for additional shower and thunderstorm activity heading into
Wednesday and Wednesday night as a cold front approaches. At this
time, models are not in the best agreement as to how all of this
pans out, and the activity on Tuesday could have some influence as
well. As a result, we'll keep chance probabilities going Wednesday
and Wednesday night and adjust from there in later updates.
Heat and humidity will persist through the short term as well.
High temperatures should range from 90 to 95 through the period,|
with lows from 70 to 75. With dew points ranging from 70 to 75,
peak afternoon heat index values of 100 to near 105 are forecast
across much of the area each afternoon today through Wednesday.
Given the marginal nature of the heat, we opted against headlines
at this time. Will address in a special weather statement for now.
Long term (Thursday through Sunday)
issued at 340 am cdt Mon aug 19 2019
the medium range guidance has trended slower with the cold front and
associated drying over the last 48 hours. At this point, confidence
in pop trends is quite low and it is reasonable to suspect that the
cold front may not make it through the entire area. The consensus
forecast now has the cold front moving through the region on
Thursday. 50-60% pops are definitely warranted for Thursday. The
drier air will lag behind the frontal wind shift, so 40-50% pops
will linger into Friday over the southern half of the region.
Over the weekend we will be on the southern fringe of the westerlies
with weak surface high pressure at the surface. Weak disturbances in
the flow aloft could help touch off a few storms Saturday through
Monday, so we will keep some lower chance pops throughout the area
each day. Dewpoints on Saturday stay under 70f, but south winds will
bring the lower 70s dewpoints back across the area for Sunday and
Monday. Saturday may have the best shot at actually being dry, but
with the forecast trending wetter, confidence is too low to leave
pops out at this time. Two days ago, Thursday through Saturday
looked like a fairly dry stretch, but now it could be a rather wet
High temperatures are forecast to be in the lower to middle 80s
Thursday through Sunday, with some upper 80s possible Monday. These
cooler temperatures may be the result of cloud cover and
precipitation as much as any advections associated with the cold
front. Won't be surprised if the forecast trends warmer with time.

other than patchy nighttime fog,VFR conditions are anticipated
through tonight. This afternoon, isolated thunderstorms may occur
mainly northwest of a kpof-kevv line. Maintained a vcsh mention
at kcgi and kmvn for that reason. Light south winds will prevail.

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.
