main concerns with this forecast package revolves around the chance
for severe storms late tonight through tomorrow morning with perhaps
a second round of potential severe storms Sunday evening night.

Beyond that there are heat concerns for Monday and Tuesday.

Tonight, a stationary boundary will extend from central kansas into
northern missouri. As we move into the 03z-06z time frame a 40-50kt
southwesterly LLJ will develop and nose into the area. This will
happen in tandem with a subtle mid-level shortwave arriving into the
area on quasi-zonal flow aloft. This will allow storms to develop
tonight in an environment of 3500-4000j kg of MUCAPE and 35-40kts of
effective shear. This will lead to a scenario where storms will
initially develop across northern missouri and northeastern kansas
with a brief large hail and damaging wind threat transitioning to
just a damaging winds threat as storms begin to push southeastward
overnight. In addition to the severe weather, an additional one to
two inches of precipitation are expected with these storms.

Localized flash flooding can not be ruled out however, widespread
flash flooding is not anticipated with flash flood guidance right
around 2.5".

Storms are expected to continue into Sunday morning before finally
pushing south of the CWA by the afternoon. Some question about how
afternoon evening storms will evolve on but it appears a strong
upper shortwave will force a cold front through the area during the
afternoon evening. The main question is if the atmosphere can
recover from morning storms. However, if it can, as GFS model
soundings suggest, there will again be 3000-4000j kg of MUCAPE to
work with which will again introduce the chance for severe storms
with hail and wind again being the threats.

The area will come under the influence of high pressure which will
glance north of the cwa. Temperatures will warm into the mid 80s to
lower 90s with areas across the southern CWA experiencing heat index
values above 100 degrees. Tuesday, high pressure shifts east of the
area and warm air advection gets underway. Highs will rise into the
low to mid 90s with heat index values in the 100-107 degree range. A
heat advisory may be need for portions of the area both days.

Tuesday night the pattern again begins to become more active as
several shortwave will bring chance for storms mid to late week this
will at least cut the hot conditions that developed early in the
week.

Aviation (for the 00z tafs through 00z Sunday evening)
issued at 628 pm cdt Sat aug 17 2019
the main concern for aviation will be the timing of a line of
thunderstorms that is expected to push through the area tonight.

Storms are expected to form over western ks tonight and develop
into a line and progress to the east. This line is expected to
reach eastern ks and western mo around 5-7z with potential lower
visibilities and strong westerly winds. This impact will be rather
brief as the feature will be rather progressive so by 11-12z the
storms will have moved into central missouri and away from the taf
terminals. Some lingering showers may be in the area for a couple
hours, butVFR conditions look to prevail for the remainder of the
period.

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.
