Severe Weather/Record Warmth on February 6-7, 2017
 
A cold front triggered scattered strong to severe thunderstorms in mild springlike air late on 02/06/2017 and early the next day. Colder conditions eventually followed as strong high pressure ("H") built over Arkansas from the northwest.

There was no snow in the forecast on February 6th/7th. It was way too mild for wintry precipitation. Instead, a cold front looming to the northwest promised to trigger scattered thunderstorms.

 

A Severe Thunderstorm Watch was posted for the northern half of Arkansas early on 02/07/2017.

Storms were expected to become strong to severe, especially over northern and central sections of the state. A Severe Thunderstorm Watch was issued, with hail was the primary concern and some wind damage possible.

Through much of the evening of the 6th, the atmosphere was capped. More specifically, a layer of warm air aloft prevented storm development. As the midnight hour approached, the cap weakened (cooling occurred aloft), and storms erupted in the Ozark Mountains of northwest Arkansas.

 

Quarter size hail (resting next to a nickel) was produced at Cabot (Lonoke County) early on 02/07/2017.

Near Salesville (Baxter County), half dollar size hail was reported. Quarter size hail pelted areas 5 miles east of Mountain Home (Baxter County), and at Cabot (Lonoke County). Large trees were pushed over by straight-line winds at Salem (Saline County). A few trees were also downed close to Macon (Pulaski County). West of Hot Springs (Garland County), several utility poles were damaged, with broken limbs on lines. There were at least 2,000 power outages counted.

 

While there was not a lot of rain overall in the twenty four hour period ending at 600 am CST on 02/07/2017, there were several bands of heavy rain. Along a couple of bands, Flash Flood Warnings were issued.

There were narrow bands of torrential rain, with rain continuing for several hours along at least a couple of bands. Nearly three inches of rain in a couple of hours caused street flooding at Gibson (Pulaski County). Interestingly, just a few miles away, less than a tenth of an inch of rain was measured at the North Little Rock Airport (Pulaski County).

Twenty four hour amounts through 600 am CST on the 7th included 2.77 inches at Marche (Pulaski County), 2.55 inches at Cabot (Lonoke County), 2.45 inches (and a 51 mph gust) at the Little Rock Air Force Base (Pulaski County), and 1.98 inches at Jasper (Newton County).

While the aforementioned front pushed into the region on the 7th, it did not exactly plow through the state. This allowed temperatures to warm well into the 70s to lower 80s. More than a dozen records were tied or broken. It was 82 degrees at Clinton (Van Buren County) and Monticello (Drew County), 81 degrees at Batesville (Independence County), Newport (Jackson County), Pine Bluff (Jefferson County), and Stuttgart (Arkansas County), and 80 degrees at El Dorado (Union County), Hot Springs (Garland County), Little Rock (Pulaski County), and Searcy (White County).

Some long standing records were eclipsed, including a 76 degree reading at Pine Bluff (Jefferson County) in 1926, and a 78 degree reading at Little Rock (Pulaski County) in 1937.

Cooler air finally surged into Arkansas on the 8th. Low temperatures on the 9th dipped in the 20s to lower 30s, with highs in the 40s and 50s.
