A winter storm will affect the region later this week, with snow spreading across much of Iowa from Wednesday night into Thursday. At this time, there are still some uncertainties, but models are beginning to lock in to a solution.
Moderate to heavy accumulations are possible in northern and northwestern Iowa, along with gusty winds and blowing/drifting snow. The strength of the system and pressure gradient would still support gusts of 30 to 40-mph. Between the snowfall rates, and these strong winds, would certainly support appreciable blowing snow potentially approaching or exceeding blizzard criteria. This could have substantial travel impacts.
Further southeast, toward central, southern and eastern Iowa, precipitation will start as rain before transitioning to snow on Thursday, resulting in lower snowfall amounts. Those with travel interests toward the latter part of the week should pay close attention to forecast updates as details regarding this winter storm become clearer.
