Weather Summary For Central And Southeast Illinois
National Weather Service Lincoln IL
356 PM CDT Sat Jul 22 2017

The cloud cover from the showers and thunderstorms this morning,
lifted off to the northeast, leaving most locations across central
and southeast Illinois with mostly sunny skies this afternoon.
Although, some cumulus clouds formed over parts of central
Illinois at mid-afternoon, masking the sunshine. Temperatures
around the area at 3 PM, ranged from 84 degrees at Paris, to 97
degrees at Lawrenceville. With dewpoints in the mid to upper 70s,
heat index values were generally in the 95 to 105 degree range.

A weak frontal boundary stretching from southern Lake Michigan,
west southwest, to near Kansas City, is starting to move south as
a cold front. Showers and thunderstorms are expected to develop
ahead of the front, across northern Missouri, central Illinois,
and central Indiana this afternoon and into the evening. Some of
these storms may be strong to severe. The frontal boundary will
settle into the Ohio Valley on Sunday, with chances for showers
and thunderstorms continuing on Sunday for the Ohio Valley. An
upper- level storm system diving in from Canada may trigger widely
scattered showers and thunderstorms across northern Illinois and
northern Indiana for Sunday afternoon. Canadian high pressure will
move into the area early next week, with cooler and less humid
conditions across the area.

Overnight low temperatures, will drop into the mid 60s to mid 70s
for much of the Midwest.

High temperatures on Sunday, will range from the lower 80s across
northeast Iowa and the southern half of Wisconsin, to the middle
90s across western Kentucky, and southern portions of Missouri and
