Area Forecast Discussion
National Weather Service Lincoln IL
242 PM CDT THU APR 21 2016

.SHORT TERM...(Tonight)
ISSUED AT 242 PM CDT Thu Apr 21 2016

Large upper level low centered over SE Iowa this afternoon expected
to slowly make its way through the Midwest this evening.  The low is
associated with enough cold air aloft and general lift to result in
some hail for the thunderstorms as they continue through the late
afternoon and early evening.  So far, majority of hail reports have
been pea sized with moderate rain and lightning.  Another round of
showers and thunderstorms are developing invof the Miss River Valley
against western Illinois and this trend will be able to continue
through midnight until the upper low moves out to the N and E, with
winds becoming more northerly and drier air slowly working into the
region behind the system.

&&

.LONG TERM...(Friday through Thursday)
ISSUED AT 242 PM CDT Thu Apr 21 2016

Morning upper air and moisture channel/ir satellite imagery showed
closed off upper low center over west central IA, with vort spokes
rotating to the east around the low. Loop into the afternoon has
shown vort max with upper low rotating to the ESE toward west
central IL, in pretty good agreement with model output.

Expect upper low to track to east overnight, dragging precipitaton
with it. Cooler air in region for start of weekend. However, next
system moves into the plains Sunday, with the result being southerly
flow over MS river valley and warmer conditions for IL. weak low and
frontal system drags into the region for Sunday night into
Monday night, bringing chance of storms.

The better chance for convection still appears to be for Wednesday,
as a significant short wave moves out of the southwest US into the
central plains. Models are a little different in the 12z run on the
strength of the low and frontal zone. This system will bare watching
through the weekend, with the potential for significant storms in
the area.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 101 PM CDT Thu Apr 21 2016
No major changes to the forecast overall. Upper low nearby
triggering afternoon showers and thunderstorms for Central
Illinois. Will be amending shortly to put in some thunder activity
in the near term for PIA and SPI. Will delay a bit to tempo other
terminals until a more immediate threat. But VCTS through the
afternoon.
