Heavy snow, strong winds and freezing rain will continue through the Upper Plains Wednesday and to make it a little more interesting, a few severe thunderstorms and possibly "thundersnow" will cover the area. The majority of the snow will fall late afternoon and through the night into Thursday. Estimate amounts vary between 5" and 10".

This storm now has a name, too. According to the Weather Channel, welcome to 'Winter Storm Walda.' So, if Waldo and Wanda had a little blizzard of their own, they would name it 'Walda.' Okay.


No travel is advised on many South Dakota roads and highways. Also, authorities closed I-90 from Sioux Falls to Rapid City Tuesday night.

Several fire stations across the area opened their doors to those without power and generators to offer emergency needs.
Power companies are asking for patience as they continue to work around the clock as damage is quite extensive.
As of 9am Wednesday morning, power is out in Tea which could be the result of a major power line down between Tall Grass and Sundowner.
UPDATE: Power poles "snapped" along basically in a row from Louise Ave toward Tea, including over I 29, which has now been shut down near the Tea exit. - Thanks Tea Storm Chasers
