Weather Extra Bar

Ready or not we are going to have more snow fall this weekend than we did during the entire month of December. That is not going to be hard. Most locations saw less than 1” of snow in December.

Our weather is going to be dry through Friday night. Low pressure over the southwest part of the nation is forecast to track northeast.

Jan 1 500 Mb Map

The low is forecast to track through Missouri Saturday and head toward Michigan by Sunday morning. Northwest of this track will be the heavier snow. This track puts that heavier snow band across eastern Iowa. This heavier band could receive more than 4” of snow (southeast of a line from Waterloo to Prairie du Chien).

Any deviation in the actual track compared to the forecast track will adjust the position of the heavier snow band. So keep updated on the forecast for any adjustments.

Here is potential liquid in the storm to be used for snow.

Jan 1 QPF

The snow is forecast to develop mid morning Saturday and taper off early Sunday morning, with the heaviest of snow falling Saturday night. The wind will be light through Saturday evening. Around 10 pm Saturday the wind will increase from the northwest as the surface low crosses the Mississippi River. At this point the wind gusts will be near 35 mph causing blowing snow with reduced visibility and making travel hazardous. The wind diminishes Sunday evening, after 6 PM.

Jan 1 Wind

In addition to the wind and snow it is going to be COLD. Sunday high temperatures will occur shortly after midnight and then drop into the single digits as the sun comes up. Temperatures remain in the single digits throughout Sunday. Combine the wind and cold Sunday and you get wind chills in the teens and 20s below zeronext week will be mainly in the single digits and possible low teens. While at night the temperatures will drop below zero.

Blog Graphic 2

There is another chance for light snow as a quick moving low moves across the state Monday night. Too early on snow amounts, but with it being so cold any amount of moisture will bring some accumulation. Once that low moves east the wind again kicks out of the northwest causing blowing snow and dangerous wind chills Tuesday.

A Look Back at a Winter Storm in December 2009

On this date we were dealing with a blizzard. Most of the state was dealing with heavy snow, strong wind and very cold temperatures. The average state snowfall from this storms was 10.2″. It would be the 3rd snowiest storm for the state.

Dec 8 Snow

Here is a look at the snow depth across the nation on the morning of December 10, 2009.

Snow Cover Update

The snow cover this morning is 17.9% across the nation. If you compare that to last year on the same date there is a big difference. On this day (Dec. 8) it is the lowest % of snow cover since at least 2003 and last year was the highest %.

The way the forecast looks today, through Christmas, the chance of any snow is very slim.

December Snow

The first two days of December have been dry and the next 7 days are forecast to remain dry. The temperature outlook through the middle of December is above normal. We might also stay dry for this stretch of time as well. Compare this to December last year.

Thundersnow in Linn County

A narrow band of heavy snow for less then an hour has been tracking southeast across eastern Iowa this evening. Areas under that band have seen a quick 0.5-1.0″ of new snow. There have also been a few reports of thunder. Look at the radar image in Linn County this evening. Yep…there was lightning so you were not hearing things. 1
