Short term (through late Wednesday night)
issued at 437 pm cdt Tue may 21 2019
line of thunderstorms is expected to move northeast across the cwa
late this afternoon and early this evening. Atmosphere has rapidly
destabilized ahead of it as 60s and lower 70 dewpoints have surged
north into the southern CWA allowing for mlcapes to jump into the
1000-1500+ j kg range. This is further evidenced by the appearance
of a well developed cumulus field that is moving northward into
the cwa. Latest rap low level convergence fields supports cams
simulated reflectivity which depicts the current line progressing
eastward across the CWA through the evening. Deep layer and low
layer shear supports the line producing damaging winds with
embedded tornadoes and perhaps some hail given the steep lapse
rates. In addition any discrete storms that do develop ahead of
the line will also be capable of producing all hazards.

Will continue the flash flood watch until midnight. While the line
will be progressive, it will have very heavy rainfall rates.

Therefore cannot rule out a flash flood threat given the already
wet ground over the area. This line will move east of the cwa
after midnight with dry conditions expect by 12z.

Wednesday looks like about one of the only dry days as the there
will be no upper systems moving across the area. By Wednesday
night however, both the nam GFS are showing another weak shortwave
moving over the area at the some time that a front will be aligned
over missouri and illinois. Will go with a chance of showers and
thunderstorms as there may be some chance for a few strong storms.

Long term (Thursday through next Tuesday)
issued at 437 pm cdt Tue may 21 2019
the extended part of the forecast will be highlighted by warm
temperatures and a chance of thunderstorms through the memorial
day weekend. The GEFS and deterministic models are in reasonable
agreement into early next week that east-west front set up
underneath quasi-zonal upper flow. This will be between a large
upper high over the southeastern CONUS and trough over the
southwest. Coverage of thunderstorms over our area will be
determined by the ultimate location of the front and how much
upper ridging will be over the cwa. For now will keep with above
normal temperatures given forecast 850mb temperatures between
15-20c and a persistent chance of thunderstorms.

Aviation (for the 18z tafs through 18z Wednesday afternoon)
issued at 1239 pm cdt Tue may 21 2019
line of thunderstorms over southwest missouri and northwest
arkansas will continue to develop and move northeast this
afternoon. These storms will move into the st. Louis area
terminals late this afternoon and early this evening with the
potential to produce wind gusts 45kts. Otherwise, extensive MVFR
and lowVFR ceilings are expected until the thunderstorms move
through during the evening hours. Then dry andVFR conditions are
expected.

Specifics for kstl:
MVFR ceilings are expected through this evening. A line of
thunderstorms will move through the terminal between 23-01z this
evening with the potential for up to 45kt or greater winds and ifr
ceilings and visibilites. Once the storms move through this
evening, then dry andVFR conditions are expected after 06z.

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.
