1125 AM CST Sat Dec 16 2017

Other than some high clouds through the morning hours, it was clear 
to partly cloudy. Low temperatures were generally in the 20s and 
30s. With plentiful sunshine through the mid to late morning hours, 
temperatures soared into the upper 40s and 50s. Winds were out of 
the southwest at 5 to 15 mph with some higher gusts up to 20 mph or 
so intermittently.

An area of high pressure will bring one more dry day, but clouds 
will increase. There will be more clouds due to an approaching storm 
system from the southwest. The system will bring good chances of 
rain tonight and into Sunday morning. Through Sunday, a half inch to 
inch of rain will be possible over the southern half of the state. 
Lesser amounts are expected farther north. 

High temperatures today will be in the mid 50s to lower 60s. Lows 
tonight will be in the upper 30s and lower 40s. Highs on Sunday will 
be in the lower 50s to mid 60s.

A weak cold front will push through from the north on Sunday, with 
rain mostly ending Sunday afternoon. The front will stall nearby, 
and will be surrounded by a lot of moisture along the Gulf Coast. A 
new system from the southwest will interact with the front, and 
bring widespread heavy rain from eastern Texas to Georgia Monday 
through Wednesday. Some of this rain will build into southern 

The new system will pass by Thursday, with dry weather expected.
On Friday, another cold front will surge into the region from 
the Plains, and will be followed by much colder air. The week
will end with much below average temperatures.

Hazardous Weather Outlook For WASHINGTON County,AR

1224 PM CST Sat Dec 16 2017

 DAY ONE  This Afternoon and Tonight.

RISK  Limited to near Elevated.
AREA  Eastern Oklahoma and Western Arkansas.
ONSET  Ongoing.


Gusty south to southwest winds to 30 mph, combined with above 
average warmth and low humidities, is yielding near elevated fire 
weather conditions this afternoon, especially across northeast 
Oklahoma and far northwest Arkansas. These conditions, combined with 
the very high fire danger due to the recent drought and cured 
vegetation, will lead to the potential for quick fire spread. 
Conditions will improve this this evening as humidities increase and 
winds subside. Light to moderate rain will also overspread the area 
tonight, which could bring a short-lived improvement to the fire 

Spotter Activation Not Expected.

 DAYS TWO THROUGH SEVEN  Sunday through Friday.
THURSDAY  Fire Weather and High Wind Potential.
FRIDAY  No Hazards.

Fire danger will increase again Thursday, as warm temperatures and 
increased southerly winds develop ahead of a strong cold front. Very 
strong northwesterly winds and sharply colder temperatures will 
follow the front set to move through the region Thursday night. contains additional information.

Historical Weather And Climate Facts For Today

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)
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: 
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)
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)
Fairbanks AK reported freezing rain and record warm temperatures. The
afternoon high of 41 degrees was 43 degrees above normal. Snow and high
winds continued to plague the mountains of southern California. Mount
Wilson CA reported two inches of rain in six hours during the early
morning, and a storm total of more than 3.50 inches of rain. (The National
Weather Summary)
Fifty-seven cities from the Southern and Central Plains to the Appalachians
reported record low temperatures for the date, including North Platte NE
with a reading of 17 degrees below zero. Squalls in the Great Lakes Region
produced 18 inches of snow at Syracuse NY, and 30 inches at Carlisle IND.
Low pressure brought heavy snow to northern New England, with 18 inches
reported at Derby VT and Saint Johnsbury VT. (The National Weather Summary)
