Area Forecast Discussion
National Weather Service Lincoln IL
700 PM CDT Wed Sep 20 2017

.SHORT TERM...(This evening through Thursday)
ISSUED AT 237 PM CDT Wed Sep 20 2017

A cold front west of the area is still forecast to move toward the
area into northwest IL this evening. Storms are expected to
develop along the front later this afternoon and move slowly
east-northeast. Airmass over the western part of the CWA is well
capped and convective clouds remain confined to the area around
the front. HiRes models show some convection reaching into
northwest parts of the CWA, but remaining northwest of the IL
river this evening. As front becomes parallel with the mid level
flow and the loss of heating, front will stall and precip will not
get very far east. Will maintain a chance of storms northwest of
the IL river tonight. Some could reach just across the river and
into the overnight hours, but by morning, precip will have
dissipated/diminished and Thursday will then be dry. Given a
washed out front tomorrow, airmass will be the same as today, so
very hot and dry conditions are expected again.

Not much cooling overnight though temps should get down into the
upper 60s with skies are clear. Highs tomorrow will be very
similar today. Near record temps are possible tomorrow, which can
be seen in the climate section below.

.LONG TERM...(Thursday night through Wednesday)
ISSUED AT 237 PM CDT Wed Sep 20 2017

Surface high pressure ridge will remain over the area through the
weekend and into the beginning of next week. And with hurricanes
Jose and Maria sitting out east in the Atlantic, the trough in the
west will remain out there as well. So, dry and above normal temps
are expected through Monday night. Models then try to bring some
precip into the area beginning Tue afternoon; however, there are
some differences in this solution. So, result is only a slight
chance of precip Tue through Wed...which will only show up in the
grids and not the worded forecast.

Above normal temps expected through Tue...upper 80s to low 90s. By
Wed, temps should begin to cool, but likely still remain above
normal. Near record temps are possible through the weekend, which
can be seen in the climate section below.

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 657 PM CDT Wed Sep 20 2017

Another mostly VFR 00Z TAF period expected across the central
Illinois terminals. Winds will remain southerly, and cloud cover
minimal. Patchy fog may develop later tonight, but should not fall
below MVFR levels. Have not included fog mention at this time due
to its expected patchy nature. Also can`t rule out a spotty shower
or storm at KPIA tonight, but the bulk of the rain threat should
stay NW of the area.
