Update
Issued at 1042 am cdt Sun may 26 2019
morning surface analysis shows a nearly stationary frontal
boundary draped across northern illinois: however, it appears the
active boundary for today will be an old outflow along the i-70
corridor. The atmosphere across the SE kilx CWA is currently
weakly unstable but strongly sheared... With mlcapes of only
500-1000j kg and 0-6km bulk shear of around 50kt. 3km NAM seems
to have the best handle on the current scattered convection from
just south of springfield into the st. Louis metro. As this
activity tracks E NE into an increasingly favorable environment,
cells will likely strengthen along the leading edge of the precip
area. Will need to keep an eye on locations along southeast of a
danville to shelbyville line through mid-afternoon as a few strong
storms will be possible. Have increased pops to likely across
this area accordingly. Further northwest, think scattered showers
will gradually come to an end from northwest to southeast by early
afternoon. High temperatures will mainly be in the upper 70s,
with lower to middle 80s along south of i-70.

Short term (today and tonight)
issued at 308 am cdt Sun may 26 2019
well to say the least, it has been another eventful night across
the midwest, as another round of severe storms passed through the
region. A strong convective band shifted into the region late
Saturday evening, and continued to gain strength over the next 6
hours. As the frontal boundary remains in northern illinois, this
allowed warm, moist air to filter into the area ahead of the band.

This inflow kept the system going, even though outflow pushed
ahead of the convective band. Numerous reports of 60+ mph winds
were associated with this system, as well as flash flooding.

Additional showers and isolated thunderstorms will continue
overnight and through the morning.

A larger, almost MCS style, system will slide through the midwest
this morning. This will continue to bring rainfall across the
area to already saturated grounds from Saturday evenings storms.

More localized flooding will be possible, especially in low-lying
and poor drainage areas.

A break in precipitation will occur later this afternoon through
the overnight. But more precipitation returns Monday as another
low pressure system shifts into the region.

Long term (Monday through Saturday)
issued at 308 am cdt Sun may 26 2019
low pressure will filter out of the rockies Monday, however as it
approaches the midwest, it will fill and become a wave
disturbance. As higher pressure in the southeastern us and high
pressure in central canada work together, this will slide across
northern illinois and the lower great lakes. The heaviest rainfall
should stay north of the cwa, which is good as plenty of rain will
occur this morning. Behind this wave, a deepening trough will
develop over the western us, creating an intensifying low pressure
system. This will shift into the central plains mid-week, with a
larger driving low dropping into eastern canada from the polar
jet. As this larger low opens the path for movement of the low
across the midwest, moisture will be lifted into the region from
the gulf. Temperatures will not warm up as much as last week, but
expecting 80s Monday and Tuesday, with another cool down during
the second half of this work week. With the passage of a cold
front, heavy rain and thunderstorms are expected to pose a threat
across central illinois, Tuesday night through Wednesday.

Behind frontal passage and low exit, the area will get a much
needed break from the wet pattern. High pressure will shift
overhead Thursday and Friday. Thursday looks to feature partly
cloudy skies, with breezy conditions. And Friday is expected to
clear out, with light winds from the west. Looking ahead to next
weekend, southerly airflow returns Friday night and Saturday,
along with another chance of precipitation.

Aviation (for the 18z tafs through 18z Monday afternoon)
issued at 1249 pm cdt Sun may 26 2019
the band of showers that passed through much of central illinois
this morning is now well east of i-55 and will impact only kcmi
for the next couple of hours. Once the showers exit into indiana,
dry conditions are expected at the terminals for the remainder of
the afternoon through this evening. Scattered convection will
re-develop along an advancing warm front toward dawn Monday... With
the greatest areal coverage concentrated along west of i-55. Have
introduced vcts at kpia kspi by 11z... Then further north to kbmi
by 14z. Will need to keep an eye on kpia as a few models suggest
a period of MVFR ceilings as the front lifts into the area. For
now have opted to keep ceilings lowVFR at kpia, but have
introduced predominant showers after 13z.

Ilx watches warnings advisories

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.
