NWS Lincoln, IL wrote its last area forecast discussion before this flash flood warning went out at Jun 30, 4:18 PM CDT, 1 hour 20 minutes earlier.

Area forecast discussion, Jun 30, 4:18 PM CDT, 1 hour 20 minutes before

Area Forecast Discussion
National Weather Service Lincoln IL
418 PM CDT Sun Jun 30 2019

.SHORT TERM...(This evening through Monday)
ISSUED AT 415 PM CDT Sun Jun 30 2019

An MCS over the northeast half of IL into western IN
has a line of strong to severe thunderstorms along and ne of a
Kewanee to Peoria to Bloomington to Robinson line, and tracking
SSE with its outflow boundary pushing sw of I-74 with northerly
wind gusts of 40-60 mph. A new severe thunderstorm watch is in
effect until 9 pm cdt for the rest of east central and southeast
CWA. Convection will likely affect areas along and east of highway
51 through sunset along with the risk of severe storms with
damaging winds, locally heavy rains and possible hail. WPC has
slight chance of excessive rainfall into this evening over ne CWA
especially over east central counties of Champaign, Vermilion,
Douglas and Edgar. Precipitable water values range from 1.3 inches
over far west central IL to 1.7-1.9 inches in east central and ne
IL.

Yet another area of convection with a 2nd developing MCS was over
the upper MS river valley into central/western WI, se MN and ne
Iowa and tracking se. This could bring more chances of convection
to areas mainly ne of I-74 later tonight into early Mon morning.
Muggy lows overnight in the lower 70s.

The best convection chances generally shift ne of CWA by late
Monday morning and Mon afternoon though can not rule out an
isolated thunderstorms from mid afternoon Mon into early Mon
evening near the IN border where CAP/CIN is weaker. Another hot
and humid day Mon with highs in the lower 90s. Heat indices to
once again peak from 97 to 105F similar to today with dewpoints in
the low to mid 70s. May eventually need a heat advisory due to
duration of heat indices peaking from 100-105F.

&&

.LONG TERM...(Monday night through Sunday)
ISSUED AT 415 PM CDT Sun Jun 30 2019

Generally have dry conditions Monday night though isolated
thunderstorms possible until dusk near the IN border. SPC day2
outlook keeps marginal risk over ne IL, ne of a LaSalle-Peru to
Dwight to Watseka line Mon afternoon and Mon evening. Think GFS
may be overdoing the qpf over portions of CWA Mon and Mon night.
The upper level ridge is weakening some on Tuesday allowing
isolated thunderstorms to develop over CWA especially Tue
afternoon into Tue evening in unstable tropical airmass. Highs
Tue of 89-93F with afternoon heat indices in the upper 90s to
around 100F with pockets of heat indices reaching 100-105 from
Lincoln south.

The 12Z model continue to show a flattening upper level ridge over
the Midwest during mid and late week and into the weekend,
allowing more disturbances to bring periodic chances of showers
and thunderstorms to the area as the unstable tropical airmass
lingers much of this week. Very warm and humid weather continues
with highs in the upper 80s to around 90F Wed thru Fri and a bit
cooler for the weekend with highs in the mid to upper 80s Sat and
low to mid 80s Sunday. Heat indices peak in the mid to upper 90s
from Wed thru Fri, and in southeast IL on Saturday and trending
downward a bit during the weekend.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 100 PM CDT Sun Jun 30 2019

The MCS continues to track SSE at 45 mph with a line of strong to
severe thunderstorms over southeast WI and northern IL. A few
showers and thunderstorms have recently developed ahead of this
line in northeast IL, north of Dwight. Strong instability ahead of
this line over central/northern IL with CAPEs of 3300-5200 j/kg.
Line of convection should continue to track SSE across central
and eastern portions of IL during mid and late afternoon, and
diminishing 1st half of this evening. Have thunderstorms with
westerly wind gusts of 30-40 kts from 21Z-24Z, starting soonest
at PIA and BMI, with SPI on sw edge of this convection. MVFR
conditions possible during mid/late afternoon with thunderstorms
especially ne CWA and vsbys possibly down to 1-2 miles in heavy
rains. A break in weather is expected tonight after sunday and
through midday Monday with convection chances focused north/ne of
central IL.
