Winter Storm: Dec. 7/8 Update #4

The winter storm is in full swing, with blizzard-like conditions beginning to occur across portions of the plains.  Many road departments are now urging to not travel as winds have increased and the snow has begun to drift across roadways, which in nighttime conditions can be very hazardous.  Total snow accumulations vary across the state of Iowa, with 3-5 inches over northwest Iowa and upwards of 6-8 inches over central and southern Iowa.  Expect a few more inches to accumulate yet tonight as the low pressure system finally pushes east of the state.  This movement east, along with its' strengthening, will bring increased winds for the plains with gusts of 40-50 mph likely.  Expect many closings for tomorrow's events and schools with roads becoming impassable during the overnight tonight.  Here is a quick updated graphical forecast from the Sioux Falls National Weather Service:
