Rain Then Colder with Wintry Precipitation (November 21-26, 2013)
 
The pattern at 900 pm CST on 11/21/2013 featured a cold front pushing into the northwest corner of Arkansas. Through November 20th, temperatures across Arkansas were running one to two degrees below normal for the month. Readings stayed subpar in the days to follow after a cold front plowed through from the northwest.

The front arrived during the evening of the 21st, and crossed the state on the 22nd. The front brought widespread rain, with winds shifting to the north and becoming breezy. 

 

In the twenty four hour period ending at 600 am CST on the 22nd, central and southern sections of the state received more than three inches of rain. Twenty four hour precipitation through 600 am CST on 11/22/2013.

Just west of Carlisle (Lonoke County), 5.12 inches was measured, with 4.25 inches at Lonoke (Lonoke County), 4.17 inches about 7 miles north-northwest of Fordyce (Dallas County), 3.68 inches at Sparkman (Dallas County), 3.42 inches at Little Dixie (Woodruff County), 3.38 inches at Rohwer (Desha County), 3.09 inches at Stuttgart (Arkansas County), and 3.01 inches at Bluff City (Nevada County).

It turned colder behind the front, with subfreezing air across the Ozark Mountains by the evening of the 22nd. Moisture was limited by this time toward the Missouri border as the front departed toward the Gulf Coast. However, there was a brief period of freezing rain/sleet in locations such as Fayetteville (Washington County), Harrison (Boone County) and Jasper (Newton County).

High temperatures on the 23rd were mostly in the 40s. Very dry air penetrated into the northern counties.

 

Dewpoint temperatures at 900 am CST on 11/24/2013. By the morning of the 24th, it was very dry statewide, with dewpoints in the single digits and teens. Temperatures were well below normal, with highs in the 20s and 30s. It was not much warmer on the 25th. Highs were only in the 30s.

At several sites, these were the coldest high temperatures ever recorded in November. At Booneville (Logan County) and Waldron (Scott County), for example, the thermometer peaked at 31 degrees on the 25th. The previous record at both locales was 32 degrees (set in 1976 on November 28th). Records at these sites go back to 1906 and 1919 respectively.

As the mercury dropped, a new storm system was on the horizon to the southwest. Moisture built from the southern Plains toward Arkansas. A storm system ("L") approached from the southern Rockies by 600 am CST on 11/25/2013.

A southwest wind flow ahead of the system will try to bring warmth/some moisture into Arkansas. Moisture will encounter colder and drier air (coming from Canada), and this may slow the progress of precipitation into the region.

 

Winter weather headlines were posted from the southern Rockies through the southern Plains and into southwest Arkansas at 908 am CST on 11/24/2013.

With cold and dry air in place, precipitation had difficulty spreading into the area initially (due to evaporation).

 

The WSR-88D (Doppler Weather Radar) showed some wintry precipitation (light snow/sleet) spreading toward western Arkansas at 1058 am CST on 11/24/2013.
Even so, there was some patchy light wintry precipitation over the region during the afternoon and evening of the 24th. Amounts were little to none.

Heading into the 25th, moisture deepened as the system neared, and this allowed precipitation to make it to the ground in earnest.

 

At least one model (on 11/24/2013) was calling for chances of accumulating wintry precipitation in Arkansas in the twenty four hour period ending at 600 pm CST on 11/25/2013.

The model showed small chances (10 to 20 percent) for at least 1" of snow across portions of the Ouachita Mountains in western sections of the state. The best chances (40 to 50 percent) for freezing rain (ice) were from southwest into central sections from De Queen (Sevier County) and Mena (Polk County) to Hot Springs (Garland County).

Water was the most abundant toward the Gulf Coast, with a cold rain noted in southern Arkansas on the 25th. During the morning hours, temperatures hovered at/below freezing for a time across the south, with a period of freezing rain and sleet.

 

Ice was the most appreciable in the southwest from Texarkana (Miller County) and Mena (Polk County) to Hot Springs (Garland County) and Little Rock (Pulaski County). Ice accruals reached a tenth to a quarter of an inch in places (on exposed objects such as cars, trees and power lines). The WSR-88D (Doppler Weather Radar) showed widespread precipitation over Arkansas at 900 am CST on 11/25/2013.

The sounding (temperature and dewpoint profile with height) at North Little Rock (Pulaski County) showed that it was cold enough for snow aloft (above 10,000 feet) at 600 am CST on 11/25/2013. Farther north, there was some freezing rain and sleet as well. A drier environment kept precipitation amounts down. In parts of the far north, amounts were negligible. Ice totals were generally under a tenth of an inch.

However, above freezing temperatures (between 5,000 and 10,000 feet) caused snow to melt, with refreezing toward the ground (sleet/freezing rain).

 

Overall, this was not a major winter storm. Ground temperatures were still warm, and roads were mostly wet. Any ice was restricted to bridges/overpasses. Unfortunately, there was a fatality reported. A woman lost control of her car (due to ice) while crossing the Strawberry River on the Arkansas Highway 289 bridge between Franklin and Horseshoe Bend (both in Izard County). She got into a head on collision with another vehicle.    

During the overnight hours of the 25th and early on the 26th, rain continued across central and southern Arkansas. Temperatures remained steady or slowly rose, with no additional ice occurring.
