.SHORT TERM...
Through this afternoon.

The cold front continues to push southward across Central Alabama.
Showers are now coming to an end across northwestern counties as
of midday. Drier and cooler air continues to plunge southward in
response to the digging longwave trough over the eastern CONUS.
Showers will continue generally along and south of the I-59
corridor with rainfall amounts remaining light. Meanwhile, 
convection is trying to develop along and just out ahead of the 
cold front that currently stretches from just south of Demopolis 
to Auburn. We certainly can't rule out some thunderstorms due to 
the moisture and limited instability present along and south of 
the I-85 corridor this afternoon. Forecast has been updated to
reflect the mention of thunderstorms across the south and current
trends.

.LONG TERM...
Sunday through Saturday.

Ridging builds in across the region on Sunday as the main trough 
axis shifts off the East Coast. The surface high is centered over 
the Mid-Mississippi Valley Sunday morning and builds eastward 
through TN/KY during the day. Expect the cold air advection behind 
the departing cold front to continue, limiting the afternoon high 
temps Sunday to the low to mid 60 for most of Central AL. 

The center of the 850mb ridging slides over Central AL Sunday 
evening through the overnight hours as the surface high shifts 
into the Central Appalachians. Expect clear skies and calm winds 
to allow for effective radiational cooling as we get into the 
early morning hours Monday. Lows will drop into the low 40s area-
wide with some locations north of I-20 and I-22 corridors dipping 
below 40. Latest guidance suggests areas in Marion, Winston, 
Blount, Etowah, and Cherokee Counties could drop into the 35-37 
degree range, so I've added mention of frost in the forecast for 
those locations forecast to drop at or below 36. 

By Monday afternoon, the upper level ridging begins to flatten to a 
more zonal flow and the surface high pressure system is situated off 
the coast from the Outer Banks. A weak shortwave impulse moves 
eastward across the Gulf Coast late Monday night into Tuesday, 
increasing cloud cover for the region, which will help limit our 
overnight cooling for Tuesday morning, especially south of the I-20 
corridor. I won't rule out an isolated shower or two from that 
shortwave along the far southern tier of counties Tuesday afternoon, 
but I think most will stay along the coastline. Guidance has trended 
much slower with the trough in the Western US for the second half of 
the week, so I've started trending PoPs downward for Wednesday, 
Thursday, and Friday. With that said, confidence remains low as 
models haven't show much run to run consistency, so I've kept at 
least mention for chance of rain into the weekend. Temperature-wise, 
with lack of significant deep moisture return, expect more 
seasonable diurnal ranges for the second half of the week with lows 
in the 50s and highs in the 60s to low 70s.

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)
