NOAA Weather Radio Off Air

July 13, 2018

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.

In the Atlantic

July 9, 2018

Here is a look at what you can see from GOES-16 Monday afternoon. There is a tropical storm off the southeast coast. Chris is forecast to strengthen to a category 1 hurricane as it moves northeast. It is forecast to then weaken in the north Atlantic by Saturday over the colder waters. The storm will remain off the east coast. The other feature is over Puerto Rico. It is the remnants of Beryl. The other feature is the light brown shading representing dust from the Sahara Desert.

The Science of Fireworks

July 3, 2018

Washington, D.C. July 4th fireworks

It’s the sign that Fourth of July is right around the corner – fireworks. The light displays decorate the skies across the United States every year to celebrate our Independence Day. All of the beauty and marvel that comes with fireworks displays is actually due to science.

Chemistry is behind the vivid displays of fireworks in a few ways. The basic formula to create fireworks combines an oxygen rich chemical with burning fuel. Additional chemicals within the package can create the different colors seen in the displays. Strontium will create red colors, titanium causes white and copper produces fireworks with a blue tint. Blue is one of the more difficult colors to achieve because the copper needs to reach a certain temperature (after all, what’s Fourth of July without red white and blue?). Fireworks produce an exothermic reaction, which means that they release energy as heat. That heat turns into the lights and colors we see in the sky.

While chemistry is responsible for many processes during fireworks explosions, physics also plays its own role. The final height of the firework depends on its initial speed. Fireworks are launched using force from an explosion, accelerating it upward. Pressure causes the fireworks to fly upwards and eventually explode outward.

Hundreds of people are injured due to fireworks. Even the handheld sparklers can burn at a temperature of 2,000°F+. Those types of temperatures can melt certain metals, so it would do similar damage to skin.

Meteorology can also affect a fireworks show. Higher humidity may tone down the otherwise vivid colors that decorate the sky. Lightning could hit an unused firework and cause injuries to any bystanders. Strong winds pose a fire hazard – and drought makes things even more dangerous. Too little wind cannot clear smoke after the explosions. When the temperature increases with height (called an “inversion”) instead of decreasing as it usually does, smoke from the fireworks display could decrease viewing quality.

Eastern Iowans should prepare for isolated showers and storms for the afternoon and evening of Fourth of July 2018.

June Rainfall

July 1, 2018

As you all know, June was an abnormally wet month.  Part of the reason for all the heavy rain, was that much of the month was spent with high humidity (high dew points).

Waterloo, Cedar Rapids and Iowa City’s rainfall totals for the month of June made it into the Top 10 wettest Junes on record.  Dubuque’s June 2018 rain total is the 18th wettest June on record.

GOES East Images

June 29, 2018

GOES East, or what was GOES16, is an AMAZING satellite. It can see so many things in such detail. Here are just a few images from the last 2 days.

Starting with this image. It shows Africa on the right side of the image and the United States on the left. You can see the dust from the Sahara Desert in the light brown color. It was moving west in the upper levels of the atmosphere.

The next image is a different channel and is able to see where the hot spots are from wildfires. The wildfires on this image show up as black spots.

This image is really cool. It was captured Thursday morning. It clearly shows the river valley fog in Iowa, Wisconsin and Minnesota.

The last image is from Friday afternoon. The smoke in central Iowa was moving east and was over eastern Iowa during the evening. The smoke originated from the wildfires mentioned above in the mountains to our west.
