Feb 23 forecast map
Temperatures will slowly warm into the teens by sunrise Tuesday and eventually into the low 30s by early afternoon. Not only will the wind direction change, as the front crosses, the temperatures will begin to fall in the afternoon as well. Late Monday night and Tuesday is going to be WINDY. Wind gusts to near 40 mph are possible. The wind diminishes Tuesday evening.

Clouds increase Tuesday night as we track low pressure southeast. Here is the forecast track.

Feb 23 Forecast Track

Light snow will develop late Wednesday morning and spread southeast across eastern Iowa in the afternoon. Your Wednesday evening commute could be slick with about 1″ of snow. The snow tapers off before 10 PM Wednesday. Here is the probabilities for 1″+ and 2″+.

Feb 23 Probability

It should be a powdery snow since the temperatures will be so cold Wednesday…highs in the teens. A light wind is expected as the snow falls.

The next chance of snow will come Saturday afternoon or evening through Sunday. Early indications are that several inches of snow are possible with this storm. Exactly where that heavier snow falls is unknown this far out. The pattern is expected to start to change this weekend. When weather pattern goes through a change like this the models have a hard time in the extended forecast. We will continue to track the storm and have more details as the weekend approaches.

Thursday Evening Update on Snow

No changes in the forecast from earlier this afternoon. We are still tracking the chance for scattered snow showers to push through the eastern part of the state after midnight and taper off Friday morning. Any accumulation will be light…less than 1″. The map below shows the chances of 1″+ snow. The percentages are very low.

Here is the forecast snow totals. There will be some locations with just trace amounts. Any accumulation will make roads slick Friday morning so use caution on the roads if you encounter any snow covered roads.

Wide Temperature Range

Waterloo: -4.7 degrees
1
Dubuque: -5.2 degrees

2
Cedar Rapids: -4.1 degrees
1
Iowa City: -5.9 degrees

The recent mild weather had done a job on our snow pack. Take a look at what 5 days of above normal temperatures have done to the snow across Iowa.

There is a chance of light snow Tuesday night into Wednesday morning. Minor accumulation is possible with areas north of Cedar Rapids with a trace to 1.0″.

Significant Snow, Wind and Cold

Bitterly cold air will continue to grip the area through the upcoming week.

A wind chill advisory is in effect for the area through 9 a.m. on Monday.  Expect to see wind chills approaching -20 to -30.  Please use extreme caution if you are outside as frostbite can occur in a matter of minutes.

On Monday, a winter storm will be approaching the area from the northwest.   A WINTER STORM WATCH is in effect for much of the KWWL viewing area from noon Monday through 3 a.m. Tuesday.  Snow is expected to start Monday afternoon and may become heavy Monday evening.   Current track of this storm would put a swath of heavy snow across and north of Hwy. 30.   Current snowfall totals are expected to range from 4 to 8″ across the KWWL viewing area.  Winds will be gusty as well causing blowing and drifting snow along with bitterly cold wind chills.

Friday Evening Weather Update

Some storms are easier to forecast than others. This one has been more difficult since there are so many different “angles” to the storm. Precipitation type, timing, amount, strong wind, bitter cold (wind chill)…all part of the weekend weather.

There is a light wintry mix developing this evening. This could make roads a bit slick tonight as the precipitation if expected to continue until about 3 or 4 AM.

Blog Graphic 3

There will be a lull in the precipitation early Saturday morning. A light wintry mix is possible early Saturday afternoon. The transition to light snow Saturday night will happen as a cold front swings through the state. The weekend weather is due to two different low pressure centers.

Jan 2 Low Tracks

The best chance of any accumulating snow is Saturday night with accumulations around 1 or 2 inches for all of eastern Iowa.

Jan 2 Snow Probabilty

The best chance of the wintry mix would be areas south and east of Cedar Rapids.

Jan 2 Freezing Drizzle

After midnight Saturday, the wind will increase from the northwest and remain strong through Sunday before diminishing Sunday evening. Temperatures at the time of the strong wind will be mainly in the single digits pushing wind chills in the teens and 20s below zero. The wind will blow any of the snow that feel Saturday night around. Roads may be slick Saturday night and Sunday.

Stay up to date on this ever changing storm, if you have to travel.
