May 27-29, 1947 Winter Storm

It has been 70 years since a major winter storm rocked parts of the Midwest, including Iowa, during the last few days of May in 1947.

A strong low pressure system tracked through Missouri into the Great Lakes Region, putting Iowa on the northwest side of the storm system.  As many of you probably know, 100 miles northwest of the center of low pressure is generally where the heaviest snow band falls.

A strong Canadian high pressure system to the north brought down the unseasonably cold temperatures, which allowed for snow to fall.

6-12 inches of snow fell from Wyoming, into Nebraska and far northwestern Iowa.  Closer to home in eastern Iowa, a few towns came in with some hefty snow totals:

Waukon: 7.5″
New Hampton: 4.0″
Decorah: 3.2″
Osage: 1.5″
Cresco: 1.0″

For more information, here’s a link from the National Weather Service in La Crosse, WI.

Winter Storm Warning and Winter Weather Advisory Sunday

All of eastern Iowa is now under either a Winter Weather Advisory or Winter Storm Warning – including Keokuk and Washington counties, which were not previously included in the Winter Storm Watch. These were issued for accumulating snow and blowing snow concerns Sunday afternoon through Monday.

Snow begins in our far northwestern counties on Sunday afternoon and the snow onset line tracks east into the evening. Breezy winds develop this afternoon then become even stronger overnight as our weather maker tracks through parts of Iowa.

The heaviest of the snow is expected late Sunday into very early Monday morning. That means that Monday morning commuters (including school buses that aren’t on Spring Break) may have travel concerns tomorrow.

By late Monday morning, snow continues but the heaviest of it should be mainly out of our area. Strong winds come from the north tomorrow morning. Snowfall rates decrease into the afternoon. Winds calm later in the day. Highs tomorrow (and today) reach the low to mid 30s across most of eastern Iowa.

Latest on Winter Storm

Here’s the latest thinking as of Saturday night on the winter storm heading to eastern Iowa for later Sunday afternoon and Monday.  There’s still a little bit of uncertainty on the track of the storm, as well as the amounts, but we are getting a better idea as the storm is now moving over land.  Winter Storm Watches have been expanded to include much of the KWWL viewing area.

Sunday will start out partly sunny, with a SE wind 10-15 mph and high temperatures in the lower and middle 30s.  After 5 PM is when we have the potential for snow to develop across our northwestern counties. The snow will overspread the area Sunday night, and could be heavy at times.  Lows tomorrow night will be in the 20s.  The Monday morning commute will likely be tricky, so plan for some extra time for your commute.

The snow will continue through the morning hours on Monday, before winding up by late morning or early afternoon.  When all is said and done, snow totals could range from 2-4″ in our far southern hometowns, to as much as 8 inches in our northern hometowns.  The storm is still developing to our west and could shift a little over the next 24 hours, so stay tuned for updates.

This snowfall will won’t be too much of a “wet” or “dry” snow, it will end up somewhere in between.  Keep that in mind when shoveling or plowing.

Winter Weather Alerts Extended for Sunday

The winter storm watch was extended early Saturday to include Grundy County and parts of southwestern Wisconsin.

Snow moves in during the afternoon from west to east, with northern counties seeing the snow first. By dinner time Sunday, snow extends as far south as highway 20. The entire eastern half of the state will have snow shortly after midnight Monday. Snow continues through the morning Monday before tapering off that afternoon.

Snow will accumulate across eastern Iowa. The heaviest snow amounts are expected north of and along highway 20. Those areas can expect an isolated area of more than six inches (6”), however, 4-6” is possible for most north of highway 20. South of highway 20, those are areas where 2-4” is possible. These values will likely change as the storm tracks closer. Stay tuned.
