Does “Heat Lightning” Exist?

July 7, 2017

The answer is simply, no.  It is a common misconception, and don’t worry, even I thought heat lightning was a “thing” when I was younger.

A lot of times in the summer months, we get several pictures of lightning sent to us with the caption “heat lightning”.  People refer to this as heat lightning, because the sky is mainly clear, and they can see flashes of lightning in the distance, and think it is caused from the heat and humidity.

The truth is pretty simple: All lightning is associated with a thunderstorm.  You are simply seeing the tops of the thunderstorm clouds (and associated lightning) from a distance.  The picture above was taken in Cedar Falls, looking southeast toward storms that popped up in the overnight hours in parts of Tama and Benton counties.  You can see the moon in the right hand corner, indicating the clear sky over Cedar Falls.

So why can’t you hear the thunder?  You are only able to hear thunder if you are within 10-15 miles from a storm.  You can see lightning up to one hundred miles away from a storm (the speed of light is faster than the speed of sound).

That being said, if you can hear thunder, you are close enough to the thunderstorm, you are close enough to be struck by lightning.  As the saying goes, “When Thunder Roars, Go Indoors.”

June 28th Tornadoes Across Eastern Iowa

July 2, 2017

June 28th was an active afternoon and evening across eastern Iowa, with several severe thunderstorm and tornado warnings across the KWWL viewing area.

Officially, there were four tornadoes confirmed in eastern Iowa.  The first one was the Central City/Prairieburg tornado, which the National Weather Service survey crews found produced EF-2 damage.

Storm Track 7 was tracking this tornado on Doppler Radar, and it was showing debris.  Below is the radar reflectivity, velocity, and tornado debris signature from around 6:50 PM, when the tornado was near heavily damaged Prairieburg.

The reds are the particles the radar is picking up moving away from the radar site (located in Davenport), and the greens are moving toward the site.  When you get them close together, that indicates rotation, and where the tornado was located.

This is the correlation coefficient, where we look for debris within the storm.  Basically, this is showing us the difference between meteorological properties, such as rain and hail (the warmer colors), and the non-meteorologist properties, such as dirt, tree branches, etc. (cooler colors).  You can see a clear sign of debris right over Prairieburg.

Tornado #2: North of Monticello

Tornado #3: Oxford Junction

A brief, weak tornado was caught on camera near Vinton.  Emergency management reports that there was minor damage to a machine shed.  The National Weather Service did not send a crew there, due to no other damage being reported.
