Area Forecast Discussion
National Weather Service Lincoln IL
634 PM CDT FRI APR 22 2016

.SHORT TERM...(Tonight)
ISSUED AT 246 PM CDT Fri Apr 22 2016

Surface and upper ridging will move into Illinois tonight allowing
winds to diminish and any remnant cloud cover to scatter out early
this evening. There appears to be a sufficient gradient to keep
light northeast flow over much of the night which should diminish
chances of radiation fog.

.LONG TERM...(Saturday through Friday)
ISSUED AT 246 PM CDT Fri Apr 22 2016

A beautiful spring weekend is on tap across central and southeast
Illinois. Upper and surface ridging will build across the region
through Sunday, providing quiet and increasingly warm conditions. In
fact, by Sunday, low-level southerly return flow on the back side of
the departing surface high will push daytime highs to around 80
degrees across the region.

An active weather period looks to be setting up for the next work
week. A mean southwest upper-level flow pattern is progged to set up
across the lower 48 states, with a disturbance forecast to eject
toward the area from the southwest states about every other day. The
first system is expected to arrive by Monday, with the next system
coming in for Wednesday. Even between the distinct short waves, the
threat for showers/storms is likely to linger across at least a
portion of the area with a surface front expected to remain in the
vicinity. At this point, it looks like Wednesday stands the best
chance to see strong/severe storms, with good shear profiles and
richer low level moisture (surface dew points likely exceeding 60 in
some areas). In any event, this pattern is supportive of
temperatures at or above normal through the period.


.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 634 PM CDT Fri Apr 22 2016

Clouds still over the area, but some clearing occurring from
northeast Illinois into central IL, effecting BMI and CMI.
PIA/DEC/SPI will see clouds through around midnight, while BMI and
CMI will become clear and remain that way overnight. Other sites
will clear as well late tonight and then skies should remain clear
through tomorrow. Cloud heights will be MVFR as well. Winds will
be northeast tonight, but as the ridge moves across the area,
winds will be lighter and variable, becoming southeast tomorrow
around the noon hour with wind speeds increasing.
