Short term (this evening through Tuesday)
issued at 220 pm cdt Mon sep 25 2017
a cold front along the the i-35 corridor is expected to
edge slowly towards our area tonight and on Tuesday keeping
most of our area unseasonably warm for another 24 to 36 hours.

The main area of showers was located along and behind the
boundary with a few of the short term models indicating some
isolated showers will be possible to its east tonight into
Tuesday morning, possibly as far east as schuyler and fulton
counties late this afternoon into early this evening. However,
forecast soundings in our area not very supportive of any
precipitation over far west central illinois tonight. May add
a mention of a shower or storm in far west central il for late
this afternoon based on the development over northeast missouri,
but won't extend it very far, if at all, into the evening hours.

Another mild to warm night over the forecast area with early
morning lows only dropping off into the mid 60s.

If the frontal boundary slows down any tomorrow, a few more record
highs will be broken tomorrow afternoon, especially across the east
and southeast areas just ahead of the cold front. Models continue
to indicate little in the way of rainfall over our area with only
slight chance pops indicated over areas west of the illinois river
on Tuesday. Warmest temps, as mentioned above, should be over east
central and southeast illinois ahead of the slow moving front with
afternoon highs ranging from the mid 80s northwest to the lower 90s
roughly along and especially east of the i-55 corridor.

Long term (Tuesday night through Monday)
issued at 220 pm cdt Mon sep 25 2017
the much anticipated major pattern change will start to take hold
over the region starting on Wednesday allowing much cooler air to
spill southeast into the region. The initial trof and associated
cold front will start to shift to our east later Wednesday into
Wednesday night with temperatures expected to drop into the upper
40s north to the middle 50s southeast. A secondary trof is expected
to sharpen up the main longwave trof over the great lakes late
Thursday into Friday which will bring in some refreshingly cool air
for next weekend when we will see afternoon highs actually struggle
to get out of the 60s across the north on Saturday with early morning
lows on Sunday in the 40s across the entire forecast area.

Aviation (for the 18z tafs through 18z Tuesday afternoon)
issued at 1232 pm cdt Mon sep 25 2017
vfr conditions are expected this forecast period. Area still
under the influence of high pressure at the surface and aloft
with forecast soundings suggesting another afternoon with some
high based cumulus at around 6000 feet. Weak cold front out to our
west will not affect the TAF sites until tomorrow with some broken
mid and high based cloud cover and little in the way of rain chances.

Surface winds will once again be quite light this afternoon and
tonight, mainly from a southerly direction, with winds veering
more southwesterly on Tuesday ahead of the approaching cold front.

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.
