Weather Summary For Central And Southeast Illinois
National Weather Service Lincoln IL
430 AM CDT Wed Jul 18 2018

High pressure over the Great Lakes brought partly cloudy skies,
and cooler temperatures to central and southeast Illinois
overnight.  Pre-dawn readings were in the lower to middle 60s.

The high pressure ridge will gradually shift east through tonight,
but still provide fair weather across the region. A low pressure 
system and associated frontal boundary over the Plains, will move 
east through the end of the work week, and spread scattered 
thunderstorms east of the Mississippi River, for Thursday and 
Thursday night. This system will linger over portions of the 
Midwest and Ohio Valley, on Friday.

High temperatures today will reach the 80s for much of the
Midwest. Lows tonight will range from the upper 50s in northern
Indiana, to the lower 70s in central Missouri.

JULY 18TH...HISTORIC WEATHER EVENTS
...1889...
A cloudburst in West Virginia along the small creeks in Wirt County,
Jackson County and Wood County claimed twenty lives. Rockport WV reported
nineteen inches of rain in two hours and ten minutes that Thursday evening.
Tygart Creek rose 22 feet in one hour, and villages were swept away on
Tygart, Slate, Tucker, and Sandy Creeks. (The Weather Channel)
...1942...
A record deluge occurred at Smethport in northern Pennsylvania, with 30.7
inches in just six hours. The downpours and resultant flooding in

One of the most "photo-genic" tornadoes touched down in the northern

quite the prima donna, staying visible to tens of thousands of persons for
thirty minutes. It was moderate in intensity, with winds of 113-157 mph,
and caused 650 thousand dollars damage. (Storm Data)
...1987...
Cool weather prevailed in the western U.S. Seven cities reported record low
temperatures for the date, including Alamosa CO with a reading of 38
degrees. The low of 52 degrees at Bakersfield CA was a record for July. Up
to eight inches of snow covered the Northern Sierra Nevada Range of
California from a storm the previous day. During that storm, winds gusting
to 52 mph at Slide Mountain NV produced a wind chill reading of 20 degrees
below zero. Susanville CA reached 17 degrees that previous day, Blue Canyon
CA dipped to a July record of 36 degrees, and the high of 44 degrees at
Klamath Falls OR smashed their previous record for July by ten degrees.
