TRACKING Potential Blizzard Conditions for Tuesday

DMA WatchesWarningsAdvisories

Heavy snow and strong winds are expected to create hazardous travel conditions over the KWWL viewing area, as well as much of the Midwest, late Monday night through Wednesday. Blizzard conditions would be most likely in our viewing area Tuesday morning through Wednesday afternoon. This means that winds will be over 35 mph and visibilities will be less than a quarter mile for over 3 hours.

You’ll want to stay ahead of this winter storm.

Winter Storm Planner

Snow Forecast DMA Hand

Now that the storm is on the mainland of the United States, our weather balloon network is able to gather important data that feeds our computer model guidance.  Some of the early runs Sunday evening are keeping a heavy band of snow in our far northwestern counties, and points to the northwest. This is where 8 to 12 inches of snow is expected, with isolated higher amounts possible.  In the central part of the area, there will be 6 to 9 inches of snow.  The southeastern part of the area will see a sharp cutoff in snow totals.  This is due to those areas being closer to the track of the low pressure, and the fact that warm air may work in late Tuesday morning or early afternoon, mixing the snow with sleet and rain.  There may be a brief changeover to all rain around Iowa City and Washington.  We’re also keeping an eye on the potential for dry air to wrap into the system.

Storm Impacts

The winds will be very strong with this system, kicking in late Tuesday morning and will be the strongest Tuesday afternoon and night. Gusts could be as high as 45 mph.

A Blizzard Watch is in effect for Tuesday and Wednesday for Black Hawk, Bremer, Butler, Chickasaw, Fayette, Grundy, and Winneshiek counties.  A Winter Storm Watch is in effect for Tuesday and Wednesday for Allamakee, Benton, Buchanan, Clayton, Delaware, Dubuque, Iowa, Jones, Linn and Tama counties.  The remainder of the KWWL viewing is not under a winter weather alert as of Sunday afternoon.

CAUCUS NIGHT: Scattered snow showers or flurries may track in around 10 PM, but the real issues don’t arrive until after Midnight Monday night.
Caucus Night Forecast

Stay tuned to KWWL for further updates.

Blizzard Conditions Tue/Wed

2

Heavy snow and strong winds are expected to create hazardous travel conditions over the KWWL viewing area, as well as much of the Midwest, late Monday night through Wednesday. It will mainly affect our viewing area Tuesday morning through Wednesday afternoon. While we could see some snow late Monday night into Tuesday morning, the heaviest snowfall is expected to be Tuesday afternoon through Tuesday night. Some snow could fall at a rate of 1 to 2″ per hour. The heaviest snow is still expected in the northwestern portions of the viewing area with many from Tama to Elkader, including Waterloo and Decorah getting 8-12″, with some isolated higher amounts. Areas to the south will depend on how much rain and sleet mix in. Anything other than snow will lower snowfall amounts, but it still looks like Cedar Rapids and Dubuque will get 6-9″ with Iowa City more in line for 2-6″.

It Has Been a Few Years For Some

It has been a few years since some forecast offices have issued a blizzard warning..this may change early next week. The map below shows the number of days since the National Weather Service forecast offices have issued a blizzard warning in their coverage area.

Calculating Wind Chill

By this time, you’ve probably heard enough of the word “wind chill.”  We’ve been under a Wind Chill Warning or Wind Chill Advisory all weekend long, and that continues into the first part of Monday (1/17).

wind chill

This is the current Wind Chill Chart that was put in place by the National Weather Service in 2001.  Wind chill is the temperature at which your body feels when exposed to the cold temperatures and the wind.  There’s actually a scientific formula put in place to calculate this value.

wind chill

The numbers that appear in this formula are known as mathematical “constants” related to heat transfer theory.  The “T” is the air temperature in Fahrenheit, and the “V” is velocity, or wind speed, in miles per hour.

As you can see, the Wind Chill Chart also calculates how quickly exposed skin can get frostbite.

Ending this on a WARMER note, the Climate Prediction Center’s latest outlook for the last week of the month shows a good chance of above average temperatures.

Tumbling Weekend Temperatures

A surge of arctic air from Canada spilled into the Midwest over the weekend.  It took temperatures from the upper 20s to lower 30s Saturday morning, to the single digits and teens by the afternoon, and below zero throughout the evening and overnight.  Wind Chills were dangerously cold at -20° to -30°, which could lead to frostbite within a matter of minutes.

Here are a look at the low temperatures recorded across eastern Iowa Sunday morning (1/10/16).  The temperature in Decorah is not 100% accurate, as there were issues with the sensor overnight.

For the big four: Waterloo, Cedar Rapids, Dubuque and Iowa City; these temperatures were the coldest in 10 to 11 months!

Saturday Sun Dogs

There’s no doubt about it, the coldest air of the season has arrived across Iowa.  Temperatures started in the 20s and 30s around midnight Saturday and fell quickly throughout the morning, afternoon and evening.  Blustery northwest winds 15-25 mph have created wind chills -15° to -30° below zero. The National Weather Service has issued a Wind Chill Advisory through Saturday morning.  Frostbite can occur in less than 30 minutes.

The cold weather has created some beautiful sites.  Western counties in the KWWL viewing area saw some clearing this afternoon, and that lead to the nature’s creation of “sun dogs.”  Sun dogs are created by sunlight interacting with the ice crystals in the upper part of the atmosphere.  Sun dogs are created when the sunlight refracts through those ice crystals and creates “spots” on either or both sides of the sun.  Often times it looks like a “half rainbow” or “multiple suns.”  These can happen anytime of the year, but are more typical during the winter months when the upper levels of the atmosphere are VERY cold.  Here’s more from the National Weather Service in La Crosse.

Here are several viewer photos sent in from Saturday 01/09/2016.  Enjoy!

Clean the Snow and Ice off

This is why you should clean the snow/ice off the top of your vehicle. It could be dangerous if you don’t.
