Area Forecast Discussion
National Weather Service Lincoln IL
1116 AM CST Sun Nov 5 2017

.UPDATE...
Issued at 1006 AM CST Sun Nov 5 2017

Frontal boundary at 10 am extends roughly from Jacksonville to
north of Rantoul. This is probably not going to make much more
progress north, and indeed Springfield has fallen from 68 to 62
degrees in the last hour. Severe threat is focusing more on areas
from Taylorville to Danville southward, where surface CAPE's are
already 1500-2000 J/kg with little capping in place. The front
will be making more of a southward push this afternoon, and should
be near I-70 by about 3-4 pm. Temperatures will be falling behind
the front, but low-mid 70s will prevail ahead of it.

In terms of the fog advisory, most locations are now up to at
least a mile, with Bloomington and Jacksonville straggling some
but still lifting. Thus, the advisory was allowed to expire.

Updated grids have been sent for the latest trends into tonight,
and zone forecasts will follow soon.

&&

.SHORT TERM...(Today and tonight)
ISSUED AT 320 AM CST Sun Nov 5 2017

A weak boundary is setting up over central Illinois this morning,
with south/southwesterly winds ushering warmer temperatures and
plenty of moisture into the southeastern portions of the state.
The moisture pooling along the boundary has resulted in some
patchy dense fog. Low lying areas and rapidly changing conditions
may make travel a little slow this morning. But observation
visibilities have been bouncing up and down for the most part
since midnight. Not widespread enough this far south to go with a
full advisory at this point, rather dealing with it as a special
weather statement.

The boundary will slowly drift this morning until the arrival of
a more potent front later in the day. In the meantime, as series
of shortwaves moving into the region will bring several rounds of
showers and thunderstorms, some of which may be severe. Severe
threat for today is still in the Enhanced category on the Day One
Outlook from SPC. Plenty of clouds over the region and ongoing
precip will help to temper the daytime heating somewhat, but warm
air advection and much of the region south of a line from SPI to
DNV in a warm sector of sorts in between systems will still result
in CAPE values generally around 1200-1500 J/kg from midday into
this evening in the south and east, lesser to the NW. Winds ahead
of the front moving around to more southwesterly, parallel and
away from the boundary, also minimizing convergence along the
boundary. However, what the system is lacking in surface based
support, bulk shear makes up for, generally greater than 50kts.
Largely uni- directional flow will limit the longevity perhaps of
discrete supercells that may form, potentially moving into a more
linear segments look. Models are not very consistent with the
timing of the waves specifically, and are struggling with the
development of storms actually behind the surface boundary
depiction. Models overall are keeping to a mid day through 03z
threat, with the greater threat moving to the eastern border this
evening once the front starts to drop south. Enough moisture that
some areas may see some localized heavy rain totals, but the major
threat will be large hail and damaging winds. That being said,
rotation will not be hard to come by, especially along the
boundary, and a few tornadoes are also possible.

.LONG TERM...(Monday through Saturday)
ISSUED AT 320 AM CST Sun Nov 5 2017

Remainder of the forecast is far more simple overall.
Monday reverts back out of the warmer weather pattern and starts
a period of highs in the 40s/50s and overnight lows in the
30s/upper 20s. Beyond continued showers invof the slow moving
boundary later on Monday night possibly pushing some rain into
southeastern IL mainly south of I-70, the extended forecast is
largely dry. Models do shift from a more zonal flow aloft to more
amplified by the end of the week, signaling a potential return of
colder air to the Midwest. And the next wave is signaled into next
weekend with the next round of precip chances.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1116 AM CST Sun Nov 5 2017

Line of thunderstorms has formed along a cold front from near
KSPI-KCMI, and the main impact over the next couple hours will be
at KCMI. Once the line passes, scattered showers will continue,
but dry conditions should prevail at the TAF sites by 00Z. IFR
ceilings will improve to MVFR levels by early evening. Some
question as to how much clearing may take place, with expansive
stratocumulus to our northwest, and higher clouds moving in from
the west after 06Z. However, will mention VFR conditions by about
06Z for now.

.ILX WATCHES/WARNINGS/ADVISORIES...
