Area Forecast Discussion
National Weather Service Lincoln IL
109 PM CDT Sat Jun 9 2018

.UPDATE...
Issued at 1040 AM CDT Sat Jun 9 2018

Updated the forecast to make adjustments to temperatures and
PoPs/Weather due to the convection systems affecting the forecast
area.

Large convective complex moved into the forecast area early this
morning from NW IL and has just weakened. However, additional
storms have developed on the strong outflow that continues sinking
to the south. Another convective cluster from southeast IA is
expected to move into west central and central IL late this
morning into the early afternoon. Another round of convection is
expected this evening at some point, but timing on this is in
question since none of the convective models have a clue with any
of the activity today.

For now, will stick with highs in the upper 80s/lower 90s, but
will monitor the next few hours. There is alot of convective cloud
cover, which is inhibiting heating in central IL. However, there
are several breaks in the clouds in between systems and this time
of year it doesn't take the atmosphere very long to recover
temperature-wise.

.SHORT TERM...(Today and tonight)
ISSUED AT 345 AM CDT Sat Jun 9 2018

A weak short wave tracking into nw IL early this morning was
producing a cluster of showers and thunderstorms over northern IL
north of I-80 and into southern WI and tracking slowly ese. A
small area of convection was over northern IN and drifting slowly
east. An outflow boundary from convection in northern IL had
passed south of Moline, Lacon and Pontiac, with mild temps in the
low to mid 70s south of this boundary over much of CWA. Lacon was
down to 67F with light east wind. Moist dewpoints were in the
mid 60s to around 70F. Latest CAM models show weak short wave
over nw IL tracking slowly se into central/northeast IL during
this morning, with scattered convection from I-74 northeast and
more isolated sw of I-74. Airmass gets very unstable this
afternoon as CAPES rise above 2500 j/kg especially north of I-70,
while wind shear stays weak. Expect isolated to scattered
convection to develop by late afternoon and become more widespread
during tonight. SPC day1 outlook has marginal risk of severe
storms late this afternoon and evening for wind and hail. Heavy
rains also a risk due to high precipitable water values of 1.5-2
inches today and peaking form 2-2.4 inches north of I-72 this
evening where highest (likely) pops are. Highs today in the upper
80s from I-74 north where more cloud cover and higher rain
chances, and lower 90s south of I-74. Afternoon heat indices peak
in the low to mid 90s with highest readings south of I-74. Muggy
lows tonight in the upper 60s and lower 70s.

.LONG TERM...(Sunday through Friday)
ISSUED AT 345 AM CDT Sat Jun 9 2018

Isolated to scattered showers and thunderstorms to continue
Sunday. Instability/CAPES become highest Sunday afternoon sw of
I-74 and this area will have marginal risk of severe storms later
Sunday afternoon into Sunday evening for wind and hail. Locally
heavy rains possible too with precipitable water values of 1.5-2
inches. Slightly cooler highs Sunday in the 85-90F range, warmest
over sw cwa and southeast IL. Heat indices Sunday afternoon peak
from 90-96F. Lows Sunday night in the upper 60s and lower 70s,
mildest sw cwa and southeast IL.

Convection chances continue Monday as airmass gets more unstable
again with CAPES rising above 2500 J/kg Monday afternoon except
2000-2500 j/kg over east central IL. Marginal risk of severe
storms over most of CWA later Monday afternoon into Monday evening
for wind and hail. Highs similar to today with upper 80s from I-74
north and lower 90s south of I-74. Heat indices peak in the 90s
Monday afternoon, warmest sw CWA.

A weak cold front to push southeast over central IL later Monday
night into Tue and likely brings more showers and thunderstorms. A
few strong thunderstorms may occur in southeast IL Tuesday
afternoon especially if front slows down. Highs Tue range from
lower 80s by Galesburg, to near 90F southeast of I-70.

Dry conditions expected to briefly return Tue night and Wed as
weak high pressure settles into the area by Wed morning. Somewhat
cooler and less humid air returns with lows Tue night in the lower
60s central IL and mid 60s southeast IL, with Galesburg possibly
getting into the upper 50s. Highs wed in the mid 80s central IL
and upper 80s southeast IL and afternoon heat indices nearly match
those numbers with lower dewpoints in the upper 50s to near 60F.

Models differ with handling more short waves ridging over top of
upper level ridge into the area from Thu on, with GFS model
staying dry from Wed thru Friday, while Ecmwf and GEM bring qpf
into area later Wed night and Thu. Will stay close to consensus
that far out with some pops returning by overnight Wed night into
Thu night, then mostly dry on Friday. Temperatures and humidity
levels appear to rise again later next week as summer pattern
prevails.

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 109 PM CDT Sat Jun 9 2018

Complex forecast scenario with periods of thunderstorms expected
in central and eastern IL this afternoon through the overnight and
early Sunday morning period.

The first batch will be impacting KSPI in the 18-20z timeframe and
possibly toward KDEC, but the storms are showing signs of
weakening. The next potential for thunderstorms are expected late
afternoon through the evening hours. The short range, convective
allowing models are doing a woeful job of forecasting the storms
with so many boundaries and interactions occurring. Could see some
storms approach the IL River valley just before 00z, working their
way toward east central IL around 03z.

The next potential for thunderstorms, again not being handled well
by the models, should be moving toward the TAF sites along the
I-74 corridor after 09-11z. The storms very well may sag farther into
central IL just after daybreak, but there is low confidence in
this scenario.
