Weather Summary For Central And Southeast Illinois
National Weather Service Lincoln IL
302 PM CST Sat Dec 16 2017

Mostly sunny skies over central Illinois through the afternoon, as
high pressure in the southeast U.S. continues to shift eastward.
Southerly winds allowed temperatures to climb well above normal,
with reports in the 50s for highs.

As the high continues east, southerly winds will linger through
the remainder of the weekend. A weather system approaching from
the southwest on Sunday will build more clouds into the region,
cooling temperatures in to the 40s. This system will also bring
the chance for scattered rain showers to the Midwest. Drier
weather, and warmer temperatures, will move in Monday and linger
through the first half of the week.

Lows tonight will range from the mid 20s in northern Illinois, to
the lower 40s in central Missouri. Highs on Sunday will top out
in the upper 30s to upper 40s, from northern Illinois to southern
Illinois.

Hazardous Weather Outlook For HANCOCK County,IL

331 PM CST Sat Dec 16 2017

 DAY ONE  THIS AFTERNOON AND TONIGHT

Patchy dense fog is possible late tonight north of U.S. Highway
30. Any dense fog that develops could deposit a layer of ice on 
roadways. Motorists should remain alert for reduced visibility and
slick roads.

 DAYS TWO THROUGH SEVEN  SUNDAY THROUGH FRIDAY

Patchy dense fog and icy roads may continue Sunday morning, north
of U.S. Highway 30.

Areas of dense fog reducing visibilties down to a quarter mile or 
less, may occur across portions of the Outlook area Sunday night 
into early Monday morning. Also, some patchy freezing drizzle may 
form in areas where the surface temperature drops below freezing 
later Sunday night into early Monday morning. The latest indications 
suggest that areas generally along and 30 miles north of the 
Interstate 80 corridor may be more favored for this activity. If the 
freezing drizzle does manage to form late Sunday night, there may be 
some risk of it lingering into the Monday morning commute.

Accumulating snow is possible Thursday through Friday. It is too 
early to forecast the exact track of the low and potential snow 
amounts. Those with travel plans late in the week should keep up 
with the latest forecast.

 SPOTTER INFORMATION STATEMENT  

Reports of any dense fog and slick road conditions tonight and
Sunday night would be appreciated.

HISTORIC WEATHER EVENTS
...1835...
New England experienced one of their coldest days of record. At noon on
that bitterly cold Wednesday the mercury stood at four degrees below at
Boston, 15 degrees below at Norfolk CT, and 17 degrees below at Hanover NH.
The temperature at Boston was 12 degrees below zero by sunset. Gale force
winds accompanied the severe cold, and that night a great New York City
fire destroyed much of the financial district. (David Ludlum)
...1869...
A bill was introduced in the House of Representatives, 41st Congress, 
calling for the taking [of] meteorological observations at the military 
stations in the interior of the continent, and for giving notice on the 
northern lakes and Atlantic seaboard of the approach and force of storms. 
This would be signed in to law February 9, 1870, by President Grant, 
establishing what would come to be called the National Weather Service. You 
can see the actual bill on-line at: 
 here.
...1917...
An ice jam closed the Ohio River between Warsaw KY and Rising Sun IN. The
thirty foot high ice jam held for 58 days, and backed up the river a
distance of 100 miles. (David Ludlum)
...1987...
A Pacific storm battered the coast of California with rain and high winds,
and dumped heavy snow on the mountains of California. Winds along the coast
gusted to 70 mph at Point Arguello, and winds in the Tehachapi Mountains of
southern California gusted to 100 mph at Wheeler Ridge. Snowfall totals
ranged up to 24 inches at Mammoth Mountain. Snow fell for two minutes at
Malibu Beach, and Disneyland was closed due to the weather for only the
second time in twenty-four years. A winter storm which began in the
Southern Rockies four days earlier finished its course producing snow and
high winds in New England. Snowfall totals ranged up to 19 inches at
Blanchard ME. (The National Weather Summary) (Storm Data)
