Weather Summary for Arkansas
National Weather Service Little Rock AR
1053 AM CDT Sat Oct 20 2018

Most of the rain had exited the state by this morning, except for
some light showers across the far southeastern portions of
Arkansas. Temperatures were in the mid to upper 40s and 50s, with
winds generally out of the north. A cold front began to enter the
state from the northwest, and will continue moving through the 
region today.

Expect mostly dry conditions with clearing skies throughout the
day. Temperatures will be in the 60s and 70s for highs, and lows
will be in the 30s and 40s. Due to the cold temperatures overnight
tonight, expect to see some patchy frost in areas, especially
across the northern sections of the state. Temperatures will be
similar on Monday, but gradually increasing through midweek.

The next chance for rain will be midweek, as another storm system
and frontal boundary approach and move through the area.

OCTOBER 20TH
HISTORIC WEATHER EVENTS
...1770...
An exceedingly great storm struck eastern New England causing extensive
coastal damage from Massachusetts to Maine, and the highest tide in 47
years. (David Ludlum)
...1983...
Remnants of Pacific Hurricane Tico caused extensive flooding in central and
south central Oklahoma. Oklahoma City set daily rainfall records with 1.45
inch on the 19th, and 6.28 inches on the 20th. (17th-21st) (The Weather
Channel)
...1987...
Cold arctic air invaded the Upper Midwest, and squalls in the Lake Superior
snowbelt produced heavy snow in eastern Ashland County and northern Iron
County of Wisconsin. Totals ranged up to 18 inches at Mellen. In the
western U.S., the record high of 69 degrees at Seattle WA was their
twenty-fifth of the year, their highest number of record highs for any
given year. Bakersfield CA reported a record 146 days in a row with daily
highs 80 degrees or above. (The National Weather Summary) (Storm Data)
...1988...
Unseasonably warm weather continued in the western U.S. In California,
afternoon highs of 96 degrees at Redding and Red Bluff were records for the
date. (The National Weather Summary)
...1989...
Forty-nine cities reported record low temperatures for the date as readings
dipped into the 20s and 30s across much of the south central and
southeastern U.S. Lows of 32 degrees at Lake Charles LA and 42 degrees at
Lakeland FL were records for October, and Little Rock AR reported their
earliest freeze of record. Snow blanketed the higher elevations of Georgia
and the Carolinas. Melbourne FL dipped to 47 degrees shortly before
midnight to surpass the record low established that morning. Showers and
thunderstorms brought heavy rain to parts of the northeastern U.S. Autumn
leaves on the ground clogged drains and ditches causing flooding. Up to
4.10 inches of rain soaked southern Vermont in three days. Flood waters
washed 600 feet of railroad track, resulting in a train derailment. (The
