NOAA Weather Radio Off Air

According to the National Weather Service in Des Moines, NOAA Weather Radio with transmitter WXL-94 at Waterloo is off the air.

Technicians have been notified about the outage, and it is estimated that the repair will happen Monday, July 16 at the earliest.

Waterloo NOAA weather radio broadcasts on Channel 7, or at frequency of 162.550 mhz, and it impacts the following counties: Black Hawk, Bremer, Buchanan, Butler, Chickasaw, Fayette, Floyd and Grundy.

Here are some of the neighboring transmitters:

It’s always good to have multiple ways to stay alert of bad weather. Another way is to download the Free Storm Track 7 Weather App on your smart phone, where alerts will be sent straight to your phone.

Lightning Facts

We are heading into the peak month when a majority of the lightning fatalities have occurred. July is ranked as the number one month. When storms approaches go inside. A catch phrase used is “When Thunder Roars Go Indoors”. Lighting is one of the weather parameters we can not predict where it is going to hit or who. Don’t have the mentality of …it won’t happen to me.

From 2006 to 2017 there were 376 people who died because they were struck by lightning. A majority of the victims were male.

Reports from April 18, 2018 Snow/Sleet/Rain/Freezing Rain/Thunder/Graupel/Rainbow Event

We had a little bit of everything yesterday as an April winter storm tracked through the KWWL viewing area. A few saw a rainbow in Bremer and Black Hawk Counties and we even had a severe thunderstorms within the snow/sleet that produced some hail. Freezing rain, rain, sleet, snow, graupel (a type of precip that looks like tiny pellets of styrofoam), hail all fell from the sky yesterday morning before transitioning to mainly snow. The mix cut down on snowfall amounts but areas in the north had mainly snow, so totals were much higher.

Accumulating Snow Monday

It’s the calm before the snow on this Super Bowl Sunday.  Tonight will be mainly clear, with lows dropping below zero across much of the KWWL viewing area.  Fortunately, the wind will be relatively light out of the northwest, turning south at 5 mph.

WINTER WEATHER ADVISORY is in effect for all counties Monday, excluding Winneshiek and Allamakee counties.  Those two counties will have 1-3″ of snow, with 3-6″ of snow across the rest of eastern Iowa.  A heavier band of snow will likely set up somewhere between Highway 30 and Interstate 80, where isolated higher amounts are possible.

The snow moves in by late morning, overspreading all of eastern Iowa during the afternoon.  This is when we are expecting the heaviest period of snow.  The snow will come to an end from west to east by early to mid evening.


Here’s the Storm Track 7 Snowfall Forecast:

Seasonal Snowfall

It’s been a relatively tame winter season, as far as snowfall goes (as we know, it’s a different story with the temperatures).  The southern part of the United States have experienced a couple bouts of wintry weather.  Here in Eastern Iowa, Waterloo and Dubuque have received a little more than 9″ of snow.  Some portions of the south have received just a few inches less.

Here’s a look at the seasonal snowfall (so far) for the United States.

Wednesday Sundogs

Many times in winter when we get very cold temperatures, we see sun dogs around sunrise and/or sunset.  This happens when the light from the sun refracts off of ice crystals in the upper levels of the atmosphere, generally within cirrus clouds.  That was the case Wednesday, where sundogs were seen at sunrise and sunset.

Here are some viewer pictures sent to us.

Wintry Weather Thursday

The first day of astronomical winter is going to bring a mix of wintry weather across eastern Iowa.  Tonight, our sky will be mostly cloudy with lows dropping into the lower and middle 20s with a southeast wind 5-10 mph.  Thursday morning, there is the potential for freezing drizzle across eastern Iowa.  Although we aren’t expecting heavy precipitation, as you know, it does not take much of a glaze to cause some problems on the roads and sidewalks.  You might want to allow a little extra time for your morning drive.

Throughout the day, moisture will increase, leading to a light wintry mix across eastern Iowa.  It may initially start off as rain south of HWY30, but as temperatures cool throughout the afternoon, freezing drizzle will transition to a light wintry mix, and eventually snow.

North of HWY 20, the transition to snow will happen sooner.  That’s where light accumulations, up to an inch, are possible.  Most locations south of HWY 20 will have a trace of snow, and a light glaze of ice.


The evening commute will be more impacted, especially across the south.  Behind this system, colder air begins to filter in.  A few lingering flurries or snow showers are possible Friday.

There is a slight chance for snow, especially across southern Iowa on Sunday, and then a couple more chances next week.  Still some uncertainty on how those systems will impact Iowa, so stay tuned for further updates.
