What's New / NOTES
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Short term (this evening through Saturday)
issued at 259 pm cdt Fri may 26 2017
clusters of thunderstorms along the southern periphery of an mcv
will track across north-central illinois this afternoon into the
early evening. Based on radar trends and output from the hrrr and
3km nam, it appears locations along north of the i-74 corridor will
be impacted through about 00z 7pm. As a result, have increased pops
to likely across this area through the remainder of the afternoon.

Once this system races into indiana, it will drag a weak cold front
southward into central illinois this evening. With strong waa
occurring throughout the entire depth of the atmosphere, mid-level
capping will be strong enough to prevent much convection from
developing along the trailing front. Have therefore only carried
slight chance pops across the southern two-thirds of the kilx cwa
from mid-evening through the overnight hours. With the boundary in
the vicinity, winds are expected to become light variable. Given
increasing boundary layer moisture (both from advection and any
rainfall that occurs this afternoon), think fog will develop
tonight. Hrrr continues to show fog developing along the i-74
corridor by around midnight, then spreading further southward across
the remainder of the area as the night progresses. Have added
patchy fog across the board accordingly.

Frontal boundary will stall along the i-70 corridor late tonight
through Saturday and will eventually serve as a focusing mechanism
for strong to potentially severe convection late Saturday. Latest
models have continued to trend later with the next round of storms,
with most high-res solutions shifting the emphasis into the evening.

Given good consensus that Saturday will be dry, have dropped pops
until late in the afternoon across the far SW cwa. Main event will
arrive Saturday evening, with models still not set on an exact
timing just yet. Nam GFS are the fastest models, with convection
developing upstream across kansas during the afternoon... Then
tracking eastward along the boundary and arriving in west-central
illinois by early evening. Meanwhile, other convective-allowing
models such as the wrf-nmm and wrf-arw delay the arrival of the
convection until late evening into the overnight hours. Storm mode
by the time the system arrives will be linear, so damaging wind
gusts with an isolated tornado threat would be most probable. At
this time, have gone with likely pops across the western half of the
cwa during the evening, then further east to the indiana border
after midnight. If trends continue, the timing may eventually need
to be adjusted a bit later.

Long term (Saturday night through Friday)
issued at 259 pm cdt Fri may 26 2017
once the Saturday night wave of convection passes to the east, it
will give the stalled frontal boundary a push to the south on
Sunday. Airmass destabilizes ahead of the front by afternoon,
resulting in scattered thunderstorm development primarily along and
south of i-70. Have included 30 pops across this area, with little
or no precip expected further north across the remainder of the
area. High temperatures on Sunday will reach the middle to upper
70s.

Pronounced upper low will dig southward through ontario into the
great lakes early next week, resulting in a cooling trend across
central illinois. A weak surface trough will sink southward around
the parent low on Monday, potentially bringing a few showers.

Convergence along the boundary will be weak and with the main upper
cold core still to the north, think areal coverage of precip will
remain low. As a result, have only mentioned slight chance pops for
showers thunder along and north of i-74 Monday afternoon. Cool dry
conditions will prevail Monday night into Tuesday before the next
potential system spreads showers across south-central illinois
Tuesday night. After that, mainly dry weather is expected until a
stronger system brings the next chance for rain by Friday.

Aviation (for the 00z tafs through 00z Saturday evening)
issued at 643 pm cdt Fri may 26 2017
main cluster of convection has now pushed into west-central
indiana:however, a trailing outflow boundary may trigger isolated
storms for the next couple of hours at the i-72 terminals. Have
carried vcts at kspi kdec kcmi through 01z accordingly. Once any
early evening convection dissipates, winds will become
light variable behind the boundary. Due to increasing low-level
moisture and rainfall across the northern counties this afternoon,
fog will develop overnight. Hrrr has been consistently showing
fog developing along the i-74 corridor around midnight, then
slowly spreading southward toward dawn. Will reduce visbys to
around 2 miles between 09z and 13z at all sites. After the morning
fog lifts, mostly sunny skies will be noted through Saturday
afternoon.

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.
