Area Forecast Discussion
National Weather Service Lincoln IL
300 PM CST Fri Feb 17 2017

.SHORT TERM...(This evening through Saturday)
ISSUED AT 300 PM CST Fri Feb 17 2017

General surface ridging over the southeastern portion of the
country...resulting in warm air being moved into Central Illinois
today with sunny skies. Unseasonably warm weather expected to
continue through the weekend. Quiet weather overall...with
southwesterly winds and temperatures in the 40s overnight. However,
the storm system moving across the southern tier of the country will
edge clouds into the southern half of the state...limiting sunshine
and the max temps tomorrow. That being said...mid 60s is still well
above climatology for mid February.

.LONG TERM...(Saturday night through Friday)
ISSUED AT 300 PM CST Fri Feb 17 2017

Main weather story across central and southeast Illinois through
most of the period is the continued well above normal temperatures.
Daytime highs will average 20-30 degrees above normal, with nighttime
lows forecast above normal daytime highs. Temperature records will
continue to be broken for at least the next few days. See climate
section of discussion for the details.

A couple weather systems are forecast to impact the area during the
period. The first arrives Monday into Tuesday. This system has
trended faster in the guidance during the past 24 hours. The models
are also trending away from a strongly split northern/southern
stream with this system. Now the front, primarily driven by the
northern stream energy, is more apt to bring showers to the area.
However, there will be minimal cooling behind the front. The second,
much stronger system, will arrive for the end of the work-week. Most
of the rainfall with this system should hold off until Friday.
Colder air will spill into the area behind this late week system,
bringing at least a brief return to more seasonable temperatures.

Issued at 1159 AM CST Fri Feb 17 2017

jet anticipated again tonight to have winds just off the sfc to
increase to 30-40 kts after midnight...reaching LLWS criteria at
least in PIA. For now...the winds over other ILX terminals are
remaining in the 25-30kt frame, but the next few model runs may
alter the next TAF issuance.
