Short term (today and tonight)
issued at 318 am cdt Fri mar 22 2019
another quiet short term forecast, as a high pressure ridge will
dominate the short term. A vort MAX will slide through the lower
great lakes region this morning, bringing the chance for some
brief clouds to sweep through eastern illinois. Other than that,
the forecast was kept about the same, except that temperatures
were increased a few degrees for today. The high pressure ridge
will remain strong through today, before beginning to fall as the
next weather system approaches the region.

Overnight will remain dry, as temperatures will drop below
freezing around the midwest. Northwesterly winds will calm
overnight, allowing radiational cooler to enhance, causing
temps to quickly fall after sunset.

Long term (Saturday through Thursday)
issued at 318 am cdt Fri mar 22 2019
the biggest things in the long term include: next weather system
to end weekend and start next week, and seasonal temperatures
through Monday before a cool down to start next week.

Saturday will start out dry, and end dry for most of the region,
some locations in western illinois will have rain move in Saturday
evening. Then overspread the state into Sunday morning, bringing
rainfall to central illinois by Sunday afternoon. Most models have
agreement on the overall timing, except the canadian, which is
about 6 hours slower at onset. This has been an issue with the
canadian over the past couple of months, especially a couple days
out. Gfs, fv3, and NAM have the system moving into the region at
06z, whereas the canadian arrives around 12z. The one difference
in the models is the pinpoint location of precipitation. They have
a generalized idea that rain will occur at specific times, but
the coverage shown on the models themselves has some minor spread.

The main low core will slide through north central illinois
Sunday afternoon and evening, with some potential for lift, cape
values are present across the southern half of illinois.

Therefore, mentions of thunderstorms remain in the forecast, and
chances have been increased from 18-06z. The new work week will
start wet, as rainfall lingers into Monday. This system will exit
Monday morning from the region, and high pressure will once again
return to the midwest.

High pressure will dominate through mid-week, before another
system looks to approach the mid-mississippi river valley during
the second half of next week.

Temperatures will remain near normal through the weekend, as
sunshine helps today and Saturday, then warm southerly winds aid
Saturday and Sunday. As the low leaves the region, cooler
northwesterly winds will return as the high shifts toward the area
for the first half of next week. Temperatures look to warm back up
mid-week and reach the 60s Thursday.

Aviation (for the 12z tafs through 12z Saturday morning)
issued at 531 am cdt Fri mar 22 2019
a mostly nice day for aviation travel around the midwest, as high
pressure dominates the region. The only issue will be gusty winds
late morning through the afternoon, with sustained 9-12kts and
gusts up to 20kts from the north arrive. Winds calm below 10kts
around 22z throughout the region, and then switch to 090 at 6kts
overnight. Ceilings will remainVFR today, with abundant
sunshine, however few clouds will be possible during the morning
into the afternoon as upper level moisture slides through the
lower great lakes.

Ilx watches warnings advisories
None.

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.
