no significant weather is expected at this time.

Long term
1213 pm cdt
Monday through Sunday...

warm moist advection will be the trend at the start of the period
and help provide temps in the 70s on Monday, while chances for
precip begin to return. More energetic flow will usher in some mid
level energy Monday into Monday evening. Strongest ascent will
likely stay just to the east southeast during this time, however,
periodic light showers are still possible with the highest chances
expected over the eastern half of the cwa.

By Tuesday into Tuesday night, will see mid upper level trough
dig across the upper midwest and great lakes region, with surface
trough and front pushing through the area. This should support
higher chances for showers and thunderstorms across much of the
cwa and given increasing forcing and flow aloft, can't rule out
the possibility for some stronger development. However, still
monitoring the extent of the instability ahead of this system.

Still a period to continue monitoring for the possibility of
strong to severe storms, but some limiting factors such as cloud
cover could impact the amount of instability in place. If cloud
cover is not an issue, could see instability easily increase
especially with higher dewpoint air in place. At this time, the
highest threat for strong to severe storms is across east central
il and northwest in.

Cooler and drier air mass returns on the backside of this system
on Wednesday, with rain chances returning Thursday night with the
approach of another system. However, with strongest ascent to the
north, these chances appear to be low across much of the cwa.

For the 00z tafs...

east winds diminish to around 5 kts and veer to the southeast
overnight under clear skies.

An upper level wave passes over eastern illinois and indiana
Monday. MVFR CIGS spread from southeast to northwest late Monday
morning. Forcing for showers will be stronger over indiana, but
a couple models indicate isolated to scattered rain showers could
occur over the eastern terminals Monday afternoon or evening. More
models suggest Monday evening, so I put a prob30 for light rain
showers in for that time frame. CIGS may be close to ifr, but i
don't have enough confidence to go with ifr at this time. Winds
become south under 10 kt around midnight Monday night.

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.
