Another strong cold front progressed southeastward across the state from the late evening of the 18th through the early morning hours of the 19th. This brought very cold temperatures to the state with overnight lows dipping down into the single digits across N/NE Arkansas during the morning hours of the 20th-21st. Highs struggled to climb above freezing those days as well.
Before the cold air could depart the region, a new storm system approached from the west. While surface temperatures remained at or below freezing, temperatures a few thousand feet above the surface were much warmer. This led to the main form of precipitation being freezing rain which led to slick roads and ice accretion from southern Oklahoma into western and northern Arkansas from the afternoon through late evening hours of the 21st.
Then it began to rain and temperatures warmed up significantly, highs ended up in the 50s and 60s from the 23rd through the 26th. Heavy rain fell on the 22nd and 23rd which led to river flooding and some areal flooding across parts of the state. Rainfall amounts exceeded 3 inches in many areas. Another item of interest noted by many across the state and region was persistent fog. After the cold air and winter weather events, warm air and rain led to widespread fog for a few consecutive days.
Cooler temperatures returned by the 27th but yet another round of rain was noted that day. Dry conditions and above normal temperatures ended the month.
