February continued to remind Iowans that the mild start to winter (Dec into early Jan) did not mean the latter half of winter would continue to be mild. In this instance, a deep 500 mb trough was maturing through the central third of the United States. The mid-level and surface low pressure features developed in the Oklahoma Panhandle region on the 11th of February and proceeded to slide and deepen as they moved northeast and into the area late on the 11th and on through the 12th. Their tracks generally took them just to the southeast of the state, putting much of eastern half of Iowa in line to see inches of snowfall, gusty winds, and falling temperatures.
As relatively warm and moist air rode the warm conveyor belt around the low pressure system, a number of areas from roughly Interstate 35 on east experienced periods of moderate snowfall that resulted in widespread 5 to 8 inches reports. As the snowfall began to wind down in magnitude on the morning of the 12th, winds picked up and carried on through the day with sustained winds often in the 25 to 30 mph range and gusts pushing 40 mph.
