What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Lincoln, IL wrote its last area forecast discussion before this river flood warning went out at May 17, 2:57 AM CDT, 2 hours 36 minutes earlier.

Area forecast discussion, May 17, 2:57 AM CDT, 2 hours 36 minutes before
Area Forecast Discussion
National Weather Service Lincoln IL
257 AM CDT Sun May 17 2020

.SYNOPSIS...
Issued at 257 AM CDT Sun May 17 2020

Scattered showers and thunderstorms will be common across central
and southeast Illinois today. Locally heavy rainfall is possible,
along with the potential for severe thunderstorms this afternoon
and early evening, highest east of I-55. A cold front will push
across the area this afternoon and evening, ending the
thunderstorms. Rain chances will linger through the start of the
work week, as an upper level low pressure system lingers over the
area.

&&

.SHORT TERM...(Today and tonight)
ISSUED AT 257 AM CDT Sun May 17 2020

Latest surface analysis placed double-barrel low pressure to our
west, one centered in NW IA and another over NE TX. A warm
frontal feature extended southeast from the NW IA low into the
northern CWA. This front delineated mid 50s dew points to the
north, from mid 60s dew points farther south. Aloft, water vapor
imagery and UA analysis showed dual closed lows spinning over
northern and southern Plains. A large area of 1.5-1.7" PW airmass
extended from the lower Mississippi Valley north into central IL.

Forecast concerns today are two-fold, with heavy rain and severe
threat. Will continue Flash Flood Watch into early evening for all
but the far northwest and southeast CWA, as most of the area
remains primed for locally heavy rainfall. This is a result of the
high PW airmass, large scale ascent ahead of the upper low, and
more focused lift ahead of embedded shortwaves in southwest mid
level flow. This will provide for rounds of locally heavy rainfall
in training thunderstorms through this morning. As we head
towards midday a strong cold front will begin pushing into the
western CWA, while surface low pressure slowly deepens towards
northern IL. If we can get some breaks in north to south oriented
rain bands ahead of the front, should develop enough instability
to support a band of low- topped strong to severe storms. While
deep layer shear is not overly impressive, strong 0-1 km shear
would promote potential for rotating supercells within the line.
Low LCLs would also favor a tornado potential, and SPC has
increased TOR probs to 5% and severe risk to slight over the
eastern 2/3 of the CWA. 00z guidance and latest CAMs have
continued to slow the front, so have backed conditional severe
threat west towards the IL River Valley at 18z, shifting east with
the front into far eastern IL towards 00z. Heavy rain and flash
flooding will also be possible with these storms.

After the front clears eastern IL during the evening, thunderstorm
chances end. Overnight the upper low begins to move into western
IL. Scattered showers may be possible, but forecast soundings have
more of a drizzly look with drying in the mid levels and a
saturated airmass below 1 km.

&&

.LONG TERM...(Monday through Saturday)
ISSUED AT 257 AM CDT Sun May 17 2020

The forecast for much of the upcoming work week will hinge on the
slow movement of the closed 500 mb low. This will remain cutoff
from the main upper flow pattern across the U.S., likely resulting
in only a slow southeast drift through late week. 00z guidance
suggest the low will reach southern IL by 12z Tue, then linger
around the Ohio/Tennessee Valley area through Friday. Given this
setup, mostly cloudy skies and scattered primarily afternoon
showers will be possible Monday and Tuesday. Temperatures will
likely be a few degrees below normal through Tuesday, before
moderating mid to late week as the low fills and and an upper
ridge begins to lean east from the Plains. If the ridge can make
it this far east by Friday and Saturday as currently advertised,
above normal temperatures could be reached. Mainly dry weather is
expected through the end of the week.

&&

.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
Issued at 1148 PM CDT Sat May 16 2020

Ceilings should decrease to predominantly MVFR with isolated IFR
overnight, while widespread shra and isolated tsra affect the
area. Vsby should be generally MVFR, with isolated IFR in
thunderstorms. Cigs/vsbys should slowly improve from late morning
into afternoon, although a line of strong thunderstorms should
develop late in the afternoon and sweep across the central IL
terminals, and may produce a short reduction in flight conditions
again. VFR conditions should return after around 00Z, although low
cigs may return again after 06Z Monday. Winds E-SE around 10 kts
overnight, shifting to southerly and increasing to 10-15 kts with
gusts around 20-25 kts late Sunday morning. Following a cold
front and the associated line of thunderstorms, winds should
switch to westerly and decrease.
