.DISCUSSION...

Tonight and Sunday...

A cold front has pushed through the area this afternoon and
ushered in cooler air. Temperatures have been in the 60s across
much of the area thanks to abundant cloud cover over the region.
Light showers continue but the coverage and intensity has
definitely waned through the afternoon, with the best convection
and even some lightning present, along the coast. The warmest
conditions have occurred in the Pine Belt this afternoon thanks to
the ability to have a quick warm up before the front and clouds
moved in. 

Through the evening, skies will clear from northwest to southeast
but winds won't decouple much as speeds should remain around
5-10kts through the night. This should limit optimal radiational
cooling conditions but temperatures should still dip into the 40s
areawide. The cooler temperatures will be in the north, along and
north of the Highway 82 corridor. It is in some of these locations
where temperatures might drop into the upper 30s, especially in
outlying areas. With high pressure moving overhead, a nice day is
expected tomorrow with plenty of sun and highs in the lower to mid
60s. /28/

Sunday night through the workweek...

Sunday night/Monday morning will be the coolest period of the season 
thus far as optimal conditions for radiational cooling will exist. 
The light winds and mostly clear skies associated with surface high 
pressure will help heat efficiently escape the lower reaches of the 
atmosphere, helping temperatures to fall into the upper 30s north of 
the I-20 corridor and near 40 degrees elsewhere. A few isolated 
patches of light frost are not out of the question in the northern 
portions of the region but there was not enough confidence in 
widespread frost to make a mention of it in the HWO.

Temperatures will begin to moderate on Monday as the surface high 
shifts east of the region but low temperatures will still fall a few 
degrees below average under mostly clear skies on Monday night. 
Moisture values will begin to increase as we get closer to midweek 
as southerly flow in the upper levels helps to stream moisture along 
the northern Gulf Coast, spurring increasing rain chances for the 
ArkLaMiss on Wednesday and Thursday. Highs will be mainly below 
average through the rest of the work week with lows ranging from 
slightly below to near average for late October.
Drier conditions look to prevail as we get closer to the weekend.

Historical Weather And Climate Facts For Today

////////////////////////////
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
National Weather Summary)(Storm Data)
