What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Short term (today and tonight)
issued at 329 am cdt Fri jun 22 2018
deep surface low is now over the mid mississippi river valley in
western il this morning, with bands of sct precip still rotating
around the parent storm. The low is slow moving and will continue
to wobble a bit over the region. With that in mind, scattered
showers and thunder will be the forecast for the day. Slightly
cooler air in the north will result in high temperatures not
getting too far out of the mid 60s NW of the illinois river.

Elsewhere will remain in the 70s. Should start to see some drying
out tonight as the low moves out to the east and some dry air
works its way southward into the region. Winds become more
northerly into the evening hours and cloudy, with lows only
dropping into the 60s.

Overall, the models have struggled with the pattern shift behind
this low, and that trend continues. The wave that has acted as a
kicker for the current system is still progged to move across the
plains tonight and into tomorrow... But thats where the
similarities end. Instead of bringing the next good chances for
showers and thunderstorms, the wave is absorbed into the next
deep wave moving into the pac NW tomorrow morning. The pattern
shift after this weekend has been through several iterations in
the last 72 hours and has not yet settled down.

Long term (Saturday through Thursday)
issued at 329 am cdt Fri jun 22 2018
Saturday is expected to continue to dry out for the region, with
relatively light winds and another warming trend as the eastern
ridge builds through the weekend. High temps in the upper
70s lower 80s for Saturday, mostly 80s for Sunday. According to
the gfs, the dry weather will be unfortunately short lived, as it
brings a wave across the southern half of the state. However, the
wave is considerably weaker than prev runs, and may well be slowly
transitioning with the new system absorbing the wave. The deeper
low over the rockies will move out across the plains late Sunday,
bringing showers through overnight Monday and into Wednesday.

Other than that, the pattern shift behind the Wednesday low has
diverged yet again, with the ECMWF setting up for a hot end of the
week.

Aviation (for the 06z tafs through 06z Friday night)
issued at 1105 pm cdt Thu jun 21 2018
ceilings continue to slowly lower late this evening and we expect
that trend to continue as an upper level low tracks across
southern illinois. Scattered showers and isolated thunderstorms
continue to rotate west around the low into east central and
central illinois. This trend will continue into Friday afternoon
before the upper low shifts off to our east during the afternoon.

Ceilings will only slowly improve late tomorrow morning but will
continue to hold on to MVFR CIGS in the afternoon. Surface winds
have shifted into the northeast over most area this evening and
we expect that to hold into the morning hours with speeds in the 8
to 13 kt range. Winds should gradually back into the north and
then northwest Friday at around 10 kts.

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.
