Short term (today and tonight)
issued at 304 am cdt Tue mar 26 2019
high pressure ridge axis over northern il this morning, keeping
the winds relatively light. Dry air moving in from the northeast
has helped with the radiational cooling under already clear skies.

Temperatures have dropped down to the upper 20s low 30s this
morning, with a few sites in the mid 20s. A cool start to the day
is reflected in the slight adjustment down to todays high temps in
the upper 40s low 50s. Clear skies and light winds are expected to
continue under the ridge through tonight, and have dropped the
forecast a degree or two below blended MOS as well. Still possibly
not cool enough, with light and variable winds under the ridge
slower to come around to more southerly than prev forecast... But
the sfc dewpoints will also potentially play a part, with a
slightly higher rh than currently.

Quiet weather overall through midweek will transition over to an
extended period of pops into the weekend.

Long term (Wednesday through Monday)
issued at 304 am cdt Tue mar 26 2019
expect a slow warming trend through Wednesday and into Thursday,
with increasing sunlight... And winds taking on a more southerly
component by Wednesday morning. By Wednesday, high temperatures
are in the upper 50s low 60s. Through Wed night and into
Thursday, those southerly winds increase with a developing storm
system over the rockies high plains. Upper pattern starts to
become a little more quasi zonal. Two deeper upper lows off of
each coast of the CONUS puts the middle of the country in a
ridging position, but another low moving across canada dampens the
wave pattern, resulting in an east west orientation aloft. At
midlevels, the ridging breaks down over the plains as well, and
much warmer air moves into the region, reflected in the high
temperatures by Thursday as the afternoon climbs to the 60s, even
with developing showers and potential thunderstorms.

Central illinois ends up with a wet forecast... Showery possible
overnight on Wed night... More of a concern from Thursday through
Saturday. A surface boundary sets up, with parallel flow aloft,
over northern il somewhere between i-80 and i-74, providing a
focus for some energy rippling along that flattened ridge.

Friday night, the low over the plains moves out and into the
midwest, dragging more precip with it (and the attendant cold
front) through Saturday. The GEFS qpf plumes are starting to show
slightly less variability as the axis of greater expected rainfall
takes shape over northern il, but the overall amount in the
forecast is trending down. The downward trend is likely due to
some clarity taking shape with the evolution of the surface low
that passes through the region without vertical resolution in
structure.

Aviation (for the 06z tafs through 06z Tuesday night)
issued at 1142 pm cdt Mon mar 25 2019
vfr conditions will continue across central and eastern illinois
through the next 24 hours. A persistent area of lower level
clouds around 5kft from SE iowa into west central il are slowly
moving to the south-southeast. These clouds should mainly stay
west of the central il TAF sites, but a few of them may move
toward kspi overnight. There is plenty of dry air that is
advecting in from the n-ne, and this should also help to erode the
lower clouds.

Otherwise, surface high pressure will move across the midwest
during the day Tuesday resulting in plenty of sunshine and a light
east wind in central il. Several of the short range models are
indicating a band of cirrus from the northern plains will move
across parts of central il Tuesday, so added a sct250 layer.

None.

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.
