(DES MOINES) A Winter Storm Watch is in effect for Pottawattamie, Shelby, Harrison and Monona counties from Saturday morning to Saturday evening.
Rod Donovan, with the National Weather Service in Des Moines, says a system is moving into the area later tonight and then through Saturday night with quite a bit of moisture moving up and at the same time an area of low pressure will move across Southeast Iowa and cold air will spill into Northwest Iowa.
“What that will do is create a line where it will switch over to snow with the precipitation,” said Donovan. “Right now it does appear the heaviest snow will be across the northwest half of the state with anywhere from 3 to 6 inches, we could see locally higher amounts of 6 to 8 inches in some of those areas, especially as you get up towards the Denison area and up towards the northeast more towards Mason City with lesser amounts on either side.”
Donovan said with the cold air coming in behind this system we could see some of the coldest temperatures of this winter season so far.
