Short term (this evening through Saturday)
issued at 309 pm cdt Fri aug 18 2017
vigorous short-wave trough noted on 19z 2pm water vapor imagery
over western wisconsin will track eastward into the great lakes
tonight. Synoptic lift associated with this feature will help
trigger scattered convection across iowa over the next couple of
hours... With this activity pushing into central illinois this
evening. Current satellite imagery is beginning to show a few
cells developing just south of a weak surface low near des moines,
iowa. These storms will become more widespread later this
afternoon as they track E SE and spill into the illinois river
valley early this evening. Hrrr has been quite consistent
today... Showing a few storms arriving across the far NW kilx cwa
around galesburg by 00z 7pm. With daytime instability gradually
waning after dark and strongest upper dynamics remaining further
north in conjunction with the short-wave, think areal coverage of
convection across central illinois will remain limited. As a
result, have opted to go with scattered wording in the forecast
for tonight. Most of the activity will push eastward into indiana
and diminish toward dawn. With partial clearing expected late
tonight and plenty of boundary layer moisture in place from
rainfall during the evening, think patchy fog will develop.

Overnight lows will drop into the lower to middle 60s. A mostly
sunny and dry day is anticipated on Saturday, with afternoon highs
topping out in the lower to middle 80s.

Long term (Saturday night through Friday)
issued at 309 pm cdt Fri aug 18 2017
once the short-wave tracks toward the east coast, a zonal flow
pattern will develop across the CONUS early next week. Rising
upper heights will allow temperatures to climb into the upper 80s
and lower 90s by Sunday and Monday, with heat index readings
reaching the middle to upper 90s Monday afternoon. While the bulk
of any significant convection will remain focused further west
across the plains, a few models are suggesting scattered storms
could potentially reach west-central illinois by Monday afternoon.

The gem is particularly bullish with its eastward push of precip,
while the ECMWF is keeping all the convection well to the W nw.

Since the flow remains flat through the period and the next major
short-wave is still off to the northwest, prefer the ecmwf
solution here. As a result, will confine pops to the far W NW cwa
on Monday and keep them in the slight to low chance category.

All models agree that a vigorous wave will drop southeastward out
of canada and dig a significant upper trough over the great lakes
by the middle and end of next week. With the corresponding cold
front progged to pass through central illinois on Tuesday, will
continue to focus likely pops at that time. Once the front passes,
cooler and drier weather will arrive late in the period... With
highs dropping into the middle to upper 70s by next Thursday and
Friday.

Aviation (for the 06z tafs through 06z Saturday night)
issued at 1217 am cdt Sat aug 19 2017
relatively strong shortwave pushing through illinois attm. Models
suggest that convective complex over iowa should dissipate before
reaching mississippi, but remnant cloud may make bring occasional
cigs to western terminals. 00z models suggest that some shallow
convection will be possible along a stalled e-w boundary over i-72
sites. Will introduce a CIGS tempo group to those terminals from
22z-02z. OtherwiseVFR and light winds can be expected.

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.
