Warmer Days Ahead

March 3, 2015

The next 48 hours are going to be cold with temperatures well below normal for this time of year. The weather pattern is going to change at the end of the week into next week. A good portion of the country will not have as much stormy weather as it has during the last couple of weeks….including Iowa.

The best positive thing is the warmer temperatures. Once we get past Thursday, Friday through the next 2 weeks temperatures are expected to be above normal. This would put afternoon highs in the 40s and 50s here in Iowa.

Monday Evening Update

March 2, 2015

Low pressure over Colorado, this evening, is forecast to track east into Kansas tonight and then turn northeast through Iowa Tuesday.

1

A wintry mix is forecast to develop after midnight and quickly taper off around noon Tuesday. As the low moves into western Iowa Tuesday morning a warm front will lift north producing snow in northern Iowa and a light wintry mix south.

Tue Storm 7 AM
Generally north of Highway 20,  1-2″ with isolated 3″ of snow along the IA/MN state line, is possible. Areas south of the highway will see a light icy glaze in the morning before temperatures warm into the upper 30s late in the morning. Here is the probability of 1″+ of snow:

Mar 1 Snow Prob

Here is the probability of 0.01″ of ice:

Mar 2 Ice

Notice the amount of precipitation is going to light, but the roads could be pretty slick at times.

By noon, the low is exiting the state and the precipitation has just about come to an end. After the cold front pushes through, the wind direction will turn to the northwest with gusts to near 35 mph at times.

Tue Storm Noon

The temperatures will become much colder as we get into Tuesday night. Wednesday morning lows will be near zero and wind chills below zero.

Just two cold days, Wednesday and Thursday, before temperatures warm into the 30s (could be some 40s) Friday into early next week.

Updated Snow Chances

February 23, 2015

The sky is clear this evening. If you look west you are able to see the planes Mars and Venus.
Feb 23 planets

 

Now to the weather. A cold front will move south across Iowa around midday switching the wind direction from the SW to the NW. Here is the forecast position of the cold front Tuesday evening.

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.

Schnacks Blog 1

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.
