Area Forecast Discussion
National Weather Service Lincoln IL
555 AM CDT Wed Jun 3 2020

.SYNOPSIS...
Issued at 334 AM CDT Wed Jun 3 2020

Another very warm and humid day will be on tap across central
Illinois today as afternoon high temperatures top out in the upper
80s to around 90 degrees. Scattered thunderstorms will develop
along an advancing cold front, with some of the storms potentially
becoming severe this afternoon and evening.

&&

.SHORT TERM...(Today and tonight)
ISSUED AT 334 AM CDT Wed Jun 3 2020

Several clusters of convection continue to track along a nearly
stationary frontal boundary draped along the Illinois/Wisconsin
border early this morning. 08z/3am radar mosaic shows one storm
complex well to the east over southern Lake Huron...while
additional clusters form upstream across northeast Iowa into far
northwest Illinois. These cells are tracking E/SE and the remnants
of this activity could potentially reach the N/NW KILX CWA in the
next 3-4 hours. Have therefore included low chance PoPs from the
Peoria area northward shortly after sunrise. The early morning
convection will tend to dissipate, with additional storms re-
developing along the slowly advancing cold front by early
afternoon. Latest CAMs have shifted convective development
slightly further north from previous runs...and this seems
reasonable given that the outflow/effective boundary currently
remains well to the north.

Airmass ahead of the front will become moderately unstable, with
HREF ensemble mean SBCAPEs reaching 3000-3500J/kg along the I-72
corridor by peak heating. As has been noted with previous model
cycles, winds aloft will be weak and the corresponding 0-6km bulk
shear values will generally range from 25-30kt. Given good
instability, but weak shear...think scattered strong to severe
storm cells will develop along the front this afternoon. Forecast
soundings continue to show a dry sub-cloud layer, indicative of
potential damaging wind gusts. In addition, slow storm movement
could lead to localized heavy rainfall and flash flooding. Based
on model consensus with a strong emphasis on the the HRW NSSL,
have focused likely PoPs along/east of I-55 this afternoon through
early evening...with most of the convection dropping south of
I-70 before midnight. Once the storms end, partial clearing will
occur across the northern half of the CWA overnight. Given very
light winds and a moist boundary layer characterized by dewpoints
in the middle 60s, would not be surprised to see fog development.
Have therefore included patchy fog everywhere north of I-70 late
tonight into early Thursday morning.

.LONG TERM...(Thursday through Tuesday)
ISSUED AT 334 AM CDT Wed Jun 3 2020

Scattered thunderstorms will continue to be possible both Thursday
and Friday, although areal coverage and intensity will be limited
by the dissipating frontal boundary and an overall lack of upper
support. 00z June 3 models are all in excellent agreement that the
upper ridge will re-build over the region this weekend, resulting
in warm/dry weather from Saturday through Monday. After that,
attention will turn to the tropics as the remnants of Tropical
Storm Cristobal currently in the southwest Gulf of Mexico near the
Yucatan Peninsula tracks northward through the lower Mississippi
River Valley. A short-wave trough pushing across the Plains is
expected to intercept this system and potentially bring heavy
rainfall to portions of the Midwest. Details remain uncertain at
this point, although the GFS/ECMWF consensus suggests the most
favored time period for rainfall across central Illinois will
likely be late Tuesday into Wednesday.

&&

.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 555 AM CDT Wed Jun 3 2020

Main aviation forecast challenge will be timing of potential
convection later today. A broken line of thunderstorms has
developed ahead of an approaching cold front early this morning
across eastern/central Iowa. These storms are tracking to the E/SE
and could potentially impact KPIA in the next 3-4 hours. Models
generally show this convection dissipating this morning, so have
kept it out of the forecast at this time. Scattered thunderstorms
are expected to re-develop this afternoon as the front approaches,
with the latest run of the HRRR tracking a line of storms across
the TAF sites between 18z and 02z. Areal coverage and exact timing
are still uncertain, so have only included VCTS until radar trends
become better established. Once the front passes, convection will
come to an end and winds will veer to the N/NW. Winds will
decrease to 5kt or less and skies will partially clear tonight,
allowing patchy fog development toward dawn.
