We first told you about this snow storm on Friday night, and how to avoid the rumors of 18 to 24 inches of snow. We are now less than 24 hours away from the first flakes beginning to fall. Most of the state will see widespread snowfall and this will lead to hazardous travel conditions by Tuesday afternoon.
The storm system will begin to approach Iowa by mid to late morning on Tuesday and will eventually work its way on up into central Iowa by the afternoon hours. Snow will have some issues falling at first due to the dry air near the surface, so it will take some time for the snow to really begin to fall as we will have to saturate the lower levels. The heaviest of the snow will fall after 4pm tomorrow afternoon and will really begin to pile up. The evening commute will be a slick one, so when leaving work tomorrow evening, plan for some extra time and take it slow out there.
The greatest snowfall totals will remain south of interstate 80, with very little accumulations the further north you go in the state. From highway 30 and to the north, only expect 1 to 2 inches. Along the highway 30 corridor and to the south, to interstate 80, expect totals of 2 to 4 inches. From interstate 80 to highway 34, expect 3 to 6 inches of snow. And from highway 34 to the Iowa/Missouri border, totals will be between 5 and 7 inches. Winds will then begin to pick up in the early evening hours tomorrow, as they will be gusting up to 30mph and this will lead to visibilities below a half a mile at times.
