Short term (through late Sunday afternoon)
issued at 504 am cst Sat feb 23 2019
main concerns in the short term are fog, severe weather, and wind.
Fog has developed early this morning across central missouri with
visibilities between 1 4-1 2sm at several obs sites. Have already
issued dense fog advisory through 9 am for several counties over the
western CWA and may need to expand or extend it depending on
observation trends over the next several hours.
Next,already have showers and isolated thunderstorms over central
and southeast missouri. These will continue to move northeast
during the morning hours in strong low level moisture convergence
underneath increasing mid level ascent ahead of the upper low seen
early this morning moving into the southern plains. The attendant
surface low will move across northeast missouri into great lakes
later today into tonight. As it does, a cold front will move
across the CWA this afternoon into early this evening. GFS nam
mass fields and cams reflectivity support that scattered
thunderstorms will move across southeast missouri into southwest
illinois ahead of the cold front. Mlcapes will be on the order of
500 j kg with 0-1km shear of around 40kts, so strong to severe
storms will be possible. Forecast soundings suggests that these
storms will be elevated, particularly west of the mississippi
river, however if these storms can become surface based they will
have some the potential to produce an isolated tornado given the
shear. These storms will move quickly east of the area by mid
Have expanded the wind advisory across the entire CWA based on
soundings. Winds will turn quickly out of the west and begin the
mix the tight gradient winds down with the cold air advection.
Forecast soundings across the area are showing 900mb winds between
45-50kts between 09-12z. This should allow wind gusts reach 45 mph
at the surface late tonight into early Sunday across the entire cwa.
Long term (Sunday night through Friday)
issued at 504 am cst Sat feb 23 2019
global models are still showing that the upper flow will be in quasi-
zonal flow through most of next week. There still looks like there
will be a shortwave trough move across the midwest midweek that
will be enough to bring a chance of rain snow Wednesday into
Thursday and a second, deeper trough that will bring another|
chance of precipitation on Friday. As mentioned yesterday, the
main polar front will stay south of the CWA during much of the
week which will keep temperatures below normal. This is supported
by the GEFS 2m plumes and the 850mb temperatures.
Aviation (for the 18z tafs through 18z Sunday afternoon)
issued at 1125 am cst Sat feb 23 2019
multiple waves of rain showers, with isod to sct ts, will
continue to push NE through the region. The rain will end this
afternoon, with a somewhat brief period of clouds becoming bkn to
sct as a dry slot moves into the area. Expect low MVFR CIGS to
then move back into the region with winds becoming westerly. These
westerly winds will be quite strong with gusts to around 40 kts.
There is some indication that brief higher gusts, around 45 kts,
will be possible, but are expected to remain short lived and
mainly at the onset of higher winds. Clouds will clear out of the
area Sun morning.

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.
