236 am cdt Tue may 30 2017

Short term (today and tonight)
issued at 236 am cdt Tue may 30 2017
upper low continues to spin just north of lake superior this
morning, with several waves rotating southeastward toward the
great lakes region. The next of these waves should start to
trigger a few showers and storms over northern illinois by midday,
with impacts in central and southeast illinois mainly late
afternoon into early evening. Coverage should remain sparse enough
for 20-30% pop's to cover the situation. With cooler air aloft now
in place, highs should largely be in the mid-upper 70s vs. The 80s
we had yesterday.

Long term (Wednesday through Monday)
issued at 236 am cdt Tue may 30 2017
broad upper trough will begin to shift eastward during mid week,
with longer range models keeping an elongated upper low in place
north of the great lakes through Friday. Warmer air aloft will
build in from the west and return highs into the 80s by Friday,
possibly Saturday as well if clouds and rain do not get out of
hand.

At mid week, high pressure will move across the midwest and keep
us dry into the first part of Thursday morning. Showers and storms
will begin to develop in the warm air advection near where the two
branches of the jet stream come together over iowa missouri. There
is good agreement with the gfs ECMWF with this pattern through
Friday, but the GFS features a significant southward shift in the
elongated low this weekend, with a more widespread shower threat
but less in the way of thunder. The ECMWF brings in a strong
shortwave Saturday with most of the rain out by Saturday evening,
followed by significant cooling as another cutoff low wobbles over
the upper peninsula area. Have kept healthy rain chances through
early Sunday for now as part of a blend, but the latter part of
the forecast remains uncertain.

Aviation (for the 06z tafs through 06z Tuesday night)
issued at 1221 am cdt Tue may 30 2017
vfr conditions to continue the next 24 hours. Only issues of
consequence for the taf's are some west winds gusting to near 20
knots late morning into the afternoon, as well as some isolated
convection late afternoon as a weak boundary settles into the
area. Right now will only mention vcts at kpia kbmi, as the
boundary arrives further south as diurnal heating is lost.

Ilx watches warnings advisories
None.

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.
