A Grab Bag of Goodies

48hourforecastsnowfallWe continue to keep an eye on the system that will move into the state tonight and will bring a chance for rain, freezing rain, and snow. This system will move in after 11pm tonight and will start off rain for everyone and there is even the potential for some rumbles of thunder across southeast Iowa. Snow will then begin to transition to snow across northwest Iowa late this evening, mainly after 3am and then will the transitions further to the southeast as the night progresses. We are still expecting the heaviest of the snow to be across north central Iowa, and this is where as much as 9″ will fall. Winds will then begin to pick up tomorrow afternoon, and they will be very gusty and this is why blizzard watches and warnings have been issued for the state.


A BLIZZARD WATCH still remains in effect for central Iowa from Thursday morning through later Thursday night. Snowfall totals in this watch are expected to be between 3 and 6 inches of snow with minor ice and sleet accumulations possible. Winds will be gusting up near 50mph and this will reduces visibilities Thursday afternoon to below a quarter of a mile.

A BLIZZARD WARNING is in effect from 9am Thursday to 6am Friday. A wintery mix of sleet and snow will develop during the overnight hours tonight across far northern Iowa, generally along and north of highway 18. Further south, rain will be common until after sunrise Thursday. Then the precipitation is forecasted to transition to all snow mid to late Thursday morning. Moderate to heavy wet snow will fall through the late morning into Thursday afternoon. Thundersnow is possible Thursday afternoon and could produce snowfall rates of 2 inches per hour at times. The very strong northwest winds in the afternoon Thursday will create widespread blizzard conditions into Thursday night. A widespread 5 to 9 inches of snow is anticipated. Higher amounts are possible especially if thundersnow develops Thursday afternoon. Winds will be gusting up to 50pmh and this will lead to near whiteout conditions at times through Thursday night.

A Winter Storm Warning has been issued from 9am Thursday to 6am Friday. A light wintry mix of snow and sleet will move in early Thursday for the morning commute. The mix will change to all snow in the morning. Heavy snow will fall Thursday afternoon and last through the early evening. The heaviest snow will fall during the afternoon with 1 to 2 inches per hour rates. 6 to 9 inches of snow are expected. Wind gusts up to 40mph could drift some roads closed.

A Winter Weather Advisory is in effect from 3am to 9am Thursday. A wintry mix early Thursday will change to all snow by late morning. The snow will become heavy and last through the early evening. The heaviest snow would fall during the afternoon with 1 to 2 inches per hour rates. This is where 6 to 9 inches of snow is expected. Roads are expected to become impassable from the blowing and drifting of the snow.

Travel is going to be very dangerous and near impossible tomorrow afternoon. If you have to be somewhere tomorrow, I would see if you can reschedule. As always we will keep you updated with the very latest on our Facebook page and right here at Iowachase.com.

  1. I am an elementary principal in SE Iowa (Ottumwa). What can we expect? Looks like we are “in the clear,” but I don’t believe in that any more after the winter we have had!
