Area Forecast Discussion
NATIONAL WEATHER SERVICE LINCOLN IL
1054 AM CDT Tue Sep 9 2014

.UPDATE...
ISSUED AT 1055 AM CDT TUE SEP 9 2014

A couple updates done this morning for the MCS with widespread
showers and scattered thunderstorms moving ese across central IL
during this morning. A few storms have been strong with gusty winds,
small hail, frequent lightning and very heavy rains. Had some street
flooding in Lincoln just before 1030 am. MCS should weaken next few
hours over central IL into early afternoon while more showers and
thunderstorms develop and lift ne late this afternoon and evening
especially over west central IL including the IL river valley as
warm front along IL/MO lift ne across central IL. Highs in the
upper 70s and lower 80s this afternoon over central IL with far
southeast IL near 85F.

&&

.SHORT TERM...(Today)
ISSUED AT 307 AM CDT TUE SEP 9 2014

Clusters of thunderstorms continue to develop across eastern Iowa
and northwestern Illinois early this morning in advance of a weak
short-wave trough.  Storms are being fed by a 30-35kt 850mb jet as
noted by the DMX VWP.  Models have been struggling with the
convective evolution, with most solutions developing the storms a
bit too far west.  With the more eastward development and general
propagation to the S/SE, have increased PoPs across the western KILX
CWA into the likely category this morning.  At this point, will keep
highest PoPs confined to locations along and west of the Illinois
River, with only slight chances as far east as a Champaign to
Taylorville line.  As nocturnal jet weakens, storms will tend to
dissipate later this morning: however, re-development could occur
along outflow boundaries later today, so will maintain low chance
PoPs through the afternoon.  Due to the clouds/precip across the
W/NW, have lowered highs into the upper 70s there, with lower to
middle 80s further east and south where sunshine will be more
prevalent.

&&

.LONG TERM...(Tonight through Monday)
ISSUED AT 307 AM CDT TUE SEP 9 2014

1002mb low pressure system will develop over western Kansas
today, then will deepen to around 995mb as it tracks into northern
Michigan by Wednesday evening. Two distinct rounds of convection
appear likely across central and southeast Illinois with this
feature...the first arriving across the Illinois River Valley late
tonight and the second impacting the entire area Wednesday
afternoon and evening.

The first round of storms will develop in an increasingly
unstable/sheared environment across Kansas/Nebraska ahead of the
approaching low this afternoon.  These storms will track E/NE across
Missouri and Iowa during the evening, then into west-central and
northwest Illinois tonight.  850mb jet streak is progged to
strengthen to between 55 and 60kt overnight, supporting the
potential for damaging wind gusts with the storms.  As a result, SPC
has placed all locations along/northwest of the Illinois River
under a Slight Risk for severe overnight. In addition to the wind
threat, precipitable water values climbing to over 2 inches will
support high rainfall rates and potential flash flooding. Have
increased PoPs to 100 percent along and northwest of a Rushville
to Minonk line accordingly and later shifts may need to evaluate
the possibility of a Flash Flood Watch across this area if the
heavy rain axis does indeed set up as expected. This first round
of convection will then continue to lift E/NE across the northern
two-thirds of the KILX CWA Wednesday morning.

Second round of storms will re-develop along approaching cold front
or effective outflow boundary from morning convection by Wednesday
afternoon and evening.  Strongest low-level jet energy will
translate into the Great Lakes by Wednesday afternoon, with highest
VGP values shifting into southern Michigan/northern Indiana.  While
this area may see the most widespread threat for severe
weather(including a few tornadoes), enough low-level wind shear will
be present further W/SW into central Illinois to support robust
convection.  The main questions will be how much destabilization
will occur in the wake of the morning storms and where will the
outflow boundary be located.  Models agree that lower 70s dewpoint
air will produce CAPE values of 1500-2500J/kg Wednesday afternoon.
This coupled with 0-6km shear values of 30-40kt will be enough to
support a severe weather threat, including large hail, damaging wind
gusts, and isolated tornadoes.  Will carry categorical PoPs across
the board.

Cold front will sink southward Wednesday night, eventually clearing
the SE CWA by early Thursday morning.  Once front passes, cooler and
drier weather will settle into the area on Thursday with high
temperatures dropping into the 60s.  Trailing 500mb trough axis is
still expected to swing through the region on Friday, although 00z
Sep 9 models have continued to slow its progress, with consensus now
bringing it across Illinois Friday night.  Given strong upper
dynamics and steep lapse rates, will carry chance PoPs across the
west Friday afternoon, then slight chances everywhere Friday night.
After that, strong Canadian high pressure will dominate the weather
through early next week, leading to much below normal temperatures.
Highs this weekend will only reach the 60s, while overnight lows dip
into the 40s.

.AVIATION...(For the 12Z TAFS through 12Z Wednesday morning)
ISSUED AT 600 AM CDT TUE SEP 9 2014

Outside any thunderstorm during this period, VFR conditions are
expected. Cluster of storms fired to our northwest late last night
and have shifted east and southeast into the PIA and BMI areas.
Main challenge will be how much further southeast these storms will
go this morning before dissipating. The storms should begin to
dissipate after 15z but it appears they will track as far east as
CMI before that occurs. A stronger system will bring another round
of more widespread showers and storms to the area, especially west
of I-55 after 04z tonight. Surface winds will be variable in
direction in and near the storms, and then pick up from the south
later this morning and into the afternoon hours with speeds of
10 to 15 kts. Winds will back a bit into the southeast tonight with
speeds around 10 kts. Low level wind shear will be possible across
the PIA and SPI areas after 06z so will include in this set of TAFs
for those locations.
