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.

TRACKING: Winter Storm Watch Sunday PM & Monday

 

A Winter Storm Watch is in effect for the counties shaded in blue late Sunday through Monday.  More winter weather alerts are likely throughout the weekend.

A winter storm tracks into the region late Sunday into Monday.  This has the potential to bring 2-6 inches of snow across eastern Iowa, with the most across our northern area.  This will likely have major impacts on the Monday morning commute.  Stay with KWWL for updated forecasts, as the amounts may shift or change a bit as new information rolls in as the storm gets closer.  As of Friday night the storm is off the west coast of the United States.

Here are the probabilities for 1″, 2″, and 4″ or more of snow from the Weather Prediction Center (Friday evening):

Weekend Snow Possible

We are not officially out of winter yet, and the extended forecast brings a few “blasts” of winter weather to eastern Iowa. A few flurries are possible tonight into Saturday morning. That won’t leave much behind as far as accumulations…maybe a trace in our far southwestern areas. We dry out and could see a little sunshine Saturday afternoon. By Sunday afternoon, more snow tracks in. That is the system we’re watching for accumulating snow. Snow continues overnight Sunday and through the day Monday.

As far as totals…things are not coming together as much as we would like. It does look like by Tuesday morning, most of the state will have some snow on the ground. The majority of snow looks like it will fall along and north of highway 20. With temperatures on Sunday and Monday warming to near freezing, some of the snow will be on the heavier side. Those who see the heaviest snow may get upwards of six inches (6”).

We stay below normal through late next week. Another chance for snow tracks in Wednesday.

Light snow across Iowa

We are tracking a narrow band of light snow in Minnesota tonight. It is moving southeast toward far northeast Iowa. It is forecast to move across Winneshiek, Allamakee and Clayton counties. Any snow accumulations will be less than 1”.

More snow is forecast to move southeast across mainly western Iowa. Parts of eastern Iowa will be on the northern edge of the 1-3” band of snow. Friday night into Saturday morning is when the snow will fall in Iowa. Areas along and south west of I-380 will see up to 1” of snow in the KWWL Viewing area.
