 A series of strong low pressure systems formed across the southern Great Plains on February 4, contributing to record warmth on February 4 and 5 in the southern Plains and lower Mississippi River Valley. High temperatures across many areas reached the 70s°F (21 – 26°C), and in Alabama temperatures reached the low 80s°F (27°C) with dew points in the middle 60s°(17 – 20°C). Dewpoints in the mid 60s°F were recorded as far north as Memphis. A strong cold front trailing the low pressure area approached the region from the west.
