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.

Update
Issued at 1000 am cdt Wed jun 20 2018
moisture channel satellite data shows low circulation center over
northwest NE and short wave extending to the south into ks
rotating to the east. Models continue to advect this wave to the
east today, triggering convection over region later this
afternoon and evening. Surface based CAPE over region about 1500
will be enough to also trigger scattered convection this afternoon
ahead of approaching wave. Soundings and low level moisture
channel shows a dry layer to cause potential for some storms to
produce spotty gusty winds.

Short term (today and tonight)
issued at 322 am cdt Wed jun 20 2018
wave moving across the northern tier of the state this morning is
expected to dampen the ridge enough to let the front settle into
central il later today. Actual location of the front is dependent
on a lot of mesoscale influences between the heat pushing in from
the sw... And the cooler air put down from any showers and
thunderstorms that develop across the region. With the cloud cover
anticipated today associated with the boundary and the precip,
temps are expected to be slightly cooler than the last few days,
although still incredibly muggy. Heat indices this afternoon from
the upper 80s to the low 90s. The front will not make it far in
the region before drifting slightly back to the north as a warm
front associated with the developing low off to our NW this
morning... Dropping into central eastern ia by tomorrow morning.

Throughout today and tonight, showers and thunderstorms will
remain periodic. With a slow moving boundary, isolated areas are
likely to see enhanced rainfall totals should any version of
training cells set up this afternoon.

Long term (Thursday through Tuesday)
issued at 322 am cdt Wed jun 20 2018
showers and thunderstorms continue through the end of the week
with a slow drift of the upper low across the midwest. Models are
starting to pick up speed with the progression of the low,
however... With the GFS and ECMWF showing a dried out Saturday,
with high temps in the upper 70s lower 80s. If the fairer weather
for Saturday pans out, it will be unfortunately short lived,
because the pattern shift behind the low. The upper low finally
moving out of the region is due to a small kicker wave behind it
to the nw... And a stronger wave moving on the pac NW coast to wrap
up the week. This series of waves sets up the potential for
another couple rounds of precip for next week, starting as early
as Sunday... And again on Tuesday. However, the more progressive
northwesterly flow will likely feel a little cooler and perhaps
more seasonal than the prolonged wet pattern for the region in the
shorter term.

Aviation (for the 18z tafs through 18z Thursday afternoon)
issued at 1235 pm cdt Wed jun 20 2018
surface low over western ia associated with upper low over
western NE will rotate a wave of pcpn development into the region
late afternoon and this evening. Therefore vcts in the forecast
for region this evening. Moisture and pcpn to remain in region
overnight, bringing MVFR CIGS by morning in periods of showers.

Some slight improvement in CIGS by end of forecast period.

Ilx watches warnings advisories
None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
