Short term (through late Wednesday night)
issued at 335 pm cdt Tue aug 20 2019
severe threat confined to crawford co. Over to st. Genevieve co and
south and is expected to be out of our area by 6 pm. There have
been several reports of wind damage with these storms as they
continue to flourish in 3500-4500 j kg air.
After storms dissipate, there is no expectation of redevelopment
Cams are showing the potential for redeveloping tsra over nebraska
so have kept chance pops toward sunrise, especially our northern
areas: quincy hannibal to north of the st. Louis and columbia metro
Long term (Thursday through next Tuesday)
issued at 335 pm cdt Tue aug 20 2019
next focus will be from Wednesday afternoon into Thursday as a 500mb
low near the up of michigan pushes an attendant surface cold front
into the area, then the boundary stalls roughly along and just south
of i-70. To the south, a steady stream of gulf moisture results in
precipitable waters in the 1.5-2.5 range. Overnight on wed, flow
above the surface becomes unidirectional for a short time, all
pointing to efficient rain producing storms. With no real
significant upstream kicker and a slow-to-move-on high over the
southern conus, there will be several rounds of thunderstorms
expected with total QPF around an inch with some localized 2 inches.
By Friday afternoon, the lingering frontal boundary will push south
as a 500 mb ridge builds in and shoves the front to tennessee.
At this time, the weekend looks mostly dry but still a chance of
isolated thunderstorms. Next chance of precip will be early next|
week Mon tues as another cold front passes through the area.
Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 650 pm cdt Tue aug 20 2019
vfr conditions, dry weather, and light s-sw surface winds are
expected at the TAF sites through much of tonight. If the
convective cirrus clouds clear out quickly this evening, this
could increase fog chances, but for now it looks to hold for
several hours tonight. A cold front to our northwest will make a
push into the region beginning around daybreak Wednesday and
continue through Wednesday afternoon, with several rounds of
showers and storms developing along it and affecting the taf
sites. Surface winds will veer NW with frontal passage, but there
is also some concern that this frontal boundary will stall late
Wednesday and into Wednesday night, maintaining the rain threat
well into Wednesday night. Where the front should push the
farthest south from, kuin, there is increasing potential for a
period of low clouds to intrude on Wednesday morning and have
added that to the taf.
Specifics for kstl:VFR, dry weather, and light S surface winds
until Wednesday morning when the first of several rounds of
showers and storms looks to affect the terminal. While there
should be an initial cold FROPA by midday, a stalled front near
the terminal late in the day could result in a more variable wind
direction. The threat for showers and storms looks to continue
well into Wednesday night.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
