National Weather Service Lincoln IL
934 AM CDT Tue Jul 17 2018

Mostly sunny skies and seasonable temperatures prevailed over
central and southeast Illinois this morning. Overnight lows ranged
from 59 in Galesburg, to 73 in Flora.

A large high pressure ridge centered over the upper Midwest, will
shift east into the Great Lakes, through mid-week. This will 
bring seasonable temperatures and dry weather to the region. The 
next chance for rainfall will occur on Thursday, when a frontal 
boundary approaches from the west.

High temperatures today will reach the 80s for much of the
Midwest, while lows tonight will drop into the 60s.
