Short term (through late Monday afternoon)
issued at 326 pm cdt Sun may 28 2017
weak cold front was moving southeastward through southeastern mo and
southwestern il this afternoon. Still getting isolated showers
along and just behind this front in southeast mo and southwest il,
and ahead of a northwest flow shortwave dropping southeastward
through our area. Any showers should dissipate or shift southeast
of the forecast area by early evening with continued clearing of the
sky. Cooler conditions are expected tonight with good radiational
cooling due to a clearing sky, surface winds becoming light, and
relatively low surface dew points late tonight. Although it will be
cooler tonight, the lows will only be a couple of degrees below
normal for late may. Another northwest flow shortwave and an
associated weak cold front may bring a few showers or thunderstorms
to parts of our area Monday afternoon. Despite increasing cloud
cover on Monday, highs will be warmer across southeast mo and
southwest il ahead of the cold front.

Long term (Monday night through next Sunday)
issued at 326 pm cdt Sun may 28 2017
the synoptic pattern at the start of the long term period will
feature a broad trough across much of the central CONUS into the
great lakes region. This regime will largely persist through the
period, keeping northwest flow in place through much of the
extended.

Tuesday will be mostly dry during the daylight hours, but a few
showers and thunderstorms may creep into portions of
northern central mo through the evening and overnight hours as a
warm front attempts to lift northward through the area.

The front should settle to the south of the area on Wednesday,
keeping the region dry. However, Thursday into the upcoming weekend
will feature the front lifting back north of the region. This will
allow for warmer and more unstable conditions to return, bringing
with it the chance for scattered showers and thunderstorms.

Temperatures Tuesday and Wednesday will be fairly seasonal (in the
upper 70s to low 80s) with low humidity values, but as the front
lifts back north the humidity will increase on Thursday into the
weekend with highs climbing back into the 80s.

Kd

Aviation (for the 06z tafs through 06z Monday night)
issued at 1131 pm cdt Sun may 28 2017
dryVFR for the rest of tonight. Will be watching a secondary cold
front which is expected to produce isolated showers storms by
early Monday afternoon. Low coverage of stroms precludes mention
in tafs. Southwest winds will veer to the west northwest behind
the front.

Specifics for kstl:
vfr conditions likely to persist through the valid TAF period.

Isolated storms should develop along cold front early Monday
afternoon but likely will not impact terminal. Winds will veer
from the southwest to the west northwest after frontal passage.

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.
