Update
Issued at 1041 am cdt Tue jun 27 2017
much cooler weather still expected today across the CWA as high
pressure continues to move southeast. Current forecast for
all parameters looks fine for remainder of the afternoon so no
update required at this time.

Short term (today and tonight)
issued at 336 am cdt Tue jun 27 2017
surface map of the country dominated by high pressure from the
plains to the atlantic coast. Aloft... A sin wave pattern has
amplified quite a bit over the last few days, with central il
firmly under northwesterly flow at h5. As the ridge shifts
eastward into the midwest, mild weather will continue for today,
albeit with a warming trend. Mostly sunny today and drier as
temperatures warm into the 70s. High pressure moving into central
il will put the region under the axis of the ridge... With lighter
winds in absence of a significant pressure gradient. As the ridge
slides slowly eastward... Winds will gain a southerly component to
them... But todays warm up will be mainly driven by sunshine
early... Then a slow transition to more southwesterly flow. Tonight
will remain dry for central il as a wave encroaches on the region
to the north. Temps tonight dropping into the 50s
again... Although west and northwest may be limited by clouds
moving into the region and limiting radiational component to the
diurnal drop.

Long term (Wednesday through Monday)
issued at 336 am cdt Tue jun 27 2017
the northwesterly flow over the midwest at 500mb modifies over the
next couple days... With a more zonal regime settling into the
region and southwesterly flow in the midlevels sets up a strong
warm air advection period. This shift opens the region to the
deep warm air over the desert sw. 850 mb temps warm from 7-8c on
Tuesday... To 17-20c by Wednesday evening. Temperatures at the
surface climb a good 7 to 9f on Wednesday and to the mid to upper
80s on Thursday. Guidance so far may be undercutting the potential
for Thursday, and to a lesser extent on Friday as temps at 850mb
spike. But cloud development on Thursday as moisture also feeds
into the region... As well as potential precip keeping the boundary
layer rh in place.

As the flow aloft becomes more zonal... A weak frontal boundary
sets up and seems to stall somewhat over the region resulting in a
prolonged period of precip chances... Slowly progressing from the
nw on Wednesday... Spreading across the state for Thursday and
Friday. Models have a bit of agreement at this point with bringing
the next wave and a potential MCS to interact with the boundary
already in place for the end of the week, Thu night thru Friday.

However, the details are fuzzy at this point, as outflows and
redevelopment will certainly change on a mesoscale. Warm end of
week likely... With stormy chances through the end of the week.

Weekend not necessarily in the clear, but chances drop briefly.

Aviation (for the 12z tafs through 12z Wednesday morning)
issued at 605 am cdt Tue jun 27 2017
efficient radiational cooling set up for central il in the wake of
precip yesterday resulted in some patchy shallow fog. Spi the only
taf site picking up on it at this point. Though cmi reporting it
in the vicinity. Either way, should burn off quickly after sunrise
and very little in the way of clouds today as high pressure
remains dominant. Otherwise, light winds from south to west
today and cirrus.

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.
