Wild Weather Pattern on January 10-18, 2017
 
Cold air (provided by the Polar Jet) pushed toward Arkansas on 01/13/2017, with mild conditions and moisture (provided by the Subtropical Jet) toward the Gulf Coast. As vastly different air masses collided, there was a wide variety of weather conditions across the middle of the country.

The weather pattern was wild heading into mid-January. Colder conditions worked toward Arkansas from the Plains on January 12th, and it was a shallow cold air mass (only a few thousand feet deep). North and west of the state, the air was subfreezing near the ground, and it was warmer aloft. Rain was expected to turn into ice, with a major ice storm unfolding from the Texas panhandle to northern and western Oklahoma, much of Kansas, central Missouri, and southeast Nebraska. Ice accruals over a half inch were in the forecast.

Ice an inch thick was reported from Beaver, OK to Dodge City, KS. The weight of the ice caused extensive tree damage and thousands of power outages. On the 15th, a National Football League game in Kansas City, MO was moved forward a few hours (from afternoon to evening) due to the ice.    

 

There was a sharp temperature contrast across a cold front on 01/13/2017. A cross section of the atmosphere indicated that cold air building into Arkansas was shallow, with subfreezing air (and ice) mainly north of the state. While it was breezy around the front, it was nothing like the windy conditions experienced on 01/10/2017.

Here at home, temperatures early on the 13th barely touched freezing in the far north in places like Harrison (Boone County) and Mountain Home (Baxter County). Even so, there was no ice. This was after readings reached into the 60s and 70s the day before. It was 79 degrees at Monticello (Drew County), and 78 degrees at El Dorado (Union County) and Texarkana (Miller County). Breezy southerly winds accompanied these springlike readings, which was nothing new.

Strong gusts were measured for several days. On the 10th, south to southwest winds (ahead of a front) gusted to 50 mph in places, including Jonesboro (Craighead County) and West Memphis (Crittenden County). There was a 49 mph gust at Harrison (Boone County). The next day, the roof of a learning resource center was destroyed by wind in Siloam Springs (Benton County). Twenty five people were evacuated.      

 

Most severe weather during this event was confined to Texas, with isolated tornadoes, wind damage, and very large hail reported. In Arkansas, there were areas of heavy rain (one to more than two inches) over parts of the state.

By the 15th/16th, a strong storm system arrived from the southwest United States. The system triggered severe storms in Texas, with four inch diameter stones in Medina, TX, and three inch diameter stones at Leakey, TX (both in southwest sections of the state). Toward Dallas, TX and Houston, TX, at least half a dozen weak (rated EF0/EF1) tornadoes were spawned.

Around here, there was no severe weather. As a matter of fact, thunder was very spotty. A shower produced a 47 mph gust at Grider Field east of Pine Bluff (Jefferson County) during the evening of the 16th.

Areas of heavy rain developed from the southern Plains to the Ohio Valley. Seven day (168 hour) amounts through 600 am CST on the 19th were over an inch-and-a-half in parts of Arkansas. Texarkana (Miller County) had 3.50 inches, with 2.94 inches at El Dorado (Union County), 2.60 inches at Highfill (Benton County), 2.08 inches at Jonesboro (Craighead County), and 1.88 inches at Blytheville (Mississippi County).

Ahead of the rain, it was very mild over the southeast states. As of the 18th, afternoon temperatures in Atlanta, GA reached at least 70 degrees on seven consecutive days, which tied a record.
