The gusty northeast wind will increase Saturday night and remain windy through Sunday blowing. This will cause blowing snow and at times reduced visibility.  The strongest wind will be from midnight Saturday through about 8 PM Sunday.

Wide Temperature Range

January 2015 has had a pretty wild swing in temperatures. Early in the month it was VERY cold and now we are in a stretch of warmer than normal conditions. Looking at the month as a whole, the monthly average temperatures through the 18th are all below normal.

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.

Light Snow Saturday Night…Frigid and Windy Sunday

The higher snow amounts, in earlier forecasts, will be lowered due to track of the storm farther to the east. Also a lot of the moisture will be used for thunderstorms to our southeast ahead of the low. 

The best chance of light snow will be Saturday night with accumulations around 1-2” across eastern Iowa. 

A strong northwest wind and cold temperatures remain in the forecast for Saturday night and Sunday. Any snow that does fall will blow around easily making travel hazardous. 

Temperatures will likely fall Saturday night all the way through Sunday into the single digits.

Wind chills will drop into the teens to 20 below zero on Sunday.

Thursday Evening Weather Update

No major changes to the forecast this evening. The only change is a slight northwest shift to the southern side of the heavier band of snow. This takes the 4″+ out of parts of Illinois and Missouri. Other than that, everything is the same from this afternoon. You should expect more wobbles in the track. That will result in the heavier snow band to adjust either NW or SE as we pin down the track of the low in the next 36 hours.

Blog Graphic 1

The chart below shows the temperature decreasing around midnight Saturday while at the same time the wind increases from the northwest. Blowing snow will make for hazardous travel Saturday night and Sunday. Those wind chills will be COLD…teens and 20s below zero. The wind will quickly diminish after 6-8 PM Sunday.

The current surface map shows the position of the low we are tracking for the snow potential this weekend.

There are no weather headlines (watch/warning/advisory) from the National Weather Service yet this evening. They want to wait until the low gets into Texas and gets a bit more organized before they “pull the trigger” on issuing anything. At that point they will have a better handle on the intial position of the low as it then starts to turn north. I would anticipate some sort of headline being issued during their morning product update around 2-4 AM Friday.

Weather Extra Bar

Here are some of our Storm Track 7 Live Weather Network stations at 8:45 pM. It is a cold evening and just going to get colder tonight. Wind chills in the teens and 20s below zero later tonight and Wednesday morning. A gusty wind Wednesday will keep it feeling cold all day.

Blog Graphic 1

After the real cold passes, temperatures are forecast to warm to the upper 20s for Friday and Saturday. I am tracking the possibility of snow to impact the area Saturday. It is too early for any details: timing, how much and where. One computer model update shows snow across Iowa. We will see how this trends over the next few days. Something I will be tracking.

After the Saturday storm moves away, another round of very cold air moves in with highs in the teens for a few days. If there is snow on the ground temperatures may be colder than that. We will have to wait and see on that at this point.
