Synopsis
Issued at 315 pm cdt Tue aug 20 2019
skies will partially clear early tonight behind today's
thunderstorm complex, however an approaching cold front from the
north will bring another chance of thunderstorms Wednesday,
although the severe weather threat will be much lower. This front
will be slow to exit the area, so showers and thunderstorms remain
possible into Thursday or Friday.

Update
Issued at 753 pm cdt Tue aug 20 2019
cloud cover has persisted late into the evening and may be slow to
clear out overnight, and may not clear out at all across portions
of the southern cwa, south of i-72, as storms continue across
arkansas into tennessee with cirrus spreading north into central
illinois. The amount of clearing will be the big wild card with
respect to fog development overnight. While temperatures
rebounded across the northern CWA back into the low 80s today,
temperature remained in the low 70s across southern counties under
thick cloud cover. Area wide, dew points in the upper 60s to
around 70 along with surface moisture from recent rain an light
winds otherwise set the stage for fog development, so if any
substantial clearing occurs, fog will become more likely.

Short term (this evening through Wednesday)
issued at 315 pm cdt Tue aug 20 2019
a shortwave ridge will traverse central il early tonight bringing
dry conditions into the area, however a cold front settling
southward into the area will allow another disturbance to track
into the area from the central plains early Wednesday bringing
additional chances for thunderstorms as the day progresses. With a
very moist and unstable air mass, SPC outlooks a marginal risk for
severe thunderstorms, mainly with a wind threat. Temperatures will
remain quite warm through Wednesday as central il remains near to
south of the front, so expect lows tonight of low 70s, and highs
Wednesday of mid 80s along i-74 to upper 80s south of i-70.

Long term (Wednesday night through Tuesday)
issued at 315 pm cdt Tue aug 20 2019
the frontal boundary will slip south of the area Wednesday night,
bringing a cooler and drier air mass, for highs only upper 70s to
lower 80s Thursday through Saturday, gradually warming into the
mid 80s by Monday and Tuesday. Chances for thunderstorms will also
sink southward with the frontal boundary, so southern areas should
see the higher chances through Friday. On Thursday, models depict
another shortwave feature swinging through the base of the large
scale trough over the area, resulting in pops from 30 percent in
the north up to 70 percent south of i-70. Saturday looks to be the
best chance for a dry day, as an upper level ridge crosses over
illinois. Following this ridge, another upper level trough and
cold front heat toward illinois from the northern plains early in
the work week for a return to thunderstorm chances.

Aviation (for the 00z tafs through 00z Wednesday evening)
issued at 635 pm cdt Tue aug 20 2019
light winds and dry conditions will be in place through the rest of
today and tonight in the wake of earlier thunderstorms. A number of
models continue to indicate that fog or low stratus will form late
tonight into Wednesday morning given the light flow and wet surface
conditions. Conditions should improve back toVFR by late morning or
early afternoon. Additional scattered showers and thunderstorms are
possible Wednesday afternoon.

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.
