Does “Heat Lightning” Exist?

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.”

As you may recall, a powerful 7.8 magnitude earthquake struck New Zealand, killing two people.  Scientists say that because of the quake, the seabed lifted nearly two meters (6 feet) in the city of Kaikoura of South Island.  Read more here, and see aerial shots of New Zealand before and after the earthquake.

Today might be the last day we see high temperatures like this again for awhile. Cedar Rapids and Iowa City tied the record. Des Moines reached 76 degrees (previous record 75 1941).

ICYMI Oct 3… Hurricane Sprites/Extra Launches/Northern Lights/October Normals

Something strange this way comes… or shows up on a far away camera from a hurricane.

Hurricane Matthew is churning through the Caribbean,producing tons of rain with winds of 130 mph as it tracks to the north. On Saturday, it also produced a phenomena that is rarely caught on camera…. sprites!

Sprites are essentially lightning bolts that go out the top of a thunderstorm. They are usually weak and not often seen and are usually a red color.  They last a very short time and are hard to catch on camera. Which is why the fact that at least 28 of them were caught on camera on Saturday is an amazing feat!

There is a little more from The Weather Channel at this link.  More color photos on another post from The Weather Channel are here.

Every 12 hours certain National Weather Service offices around the country send a balloon (radiosonde)  in the sky to gather valuable data. The stars on the map below show where the balloons are launched from.

After the data from the balloon is sent back to the office it is then put into computers to help with the forecast.  The idea is, the more current and reliable data you get into the calculations, the  forecast output (forecast information) would be closer to reality. Now because of Matthew, a large hurricane forecast to run up the east coast this week, they are putting more balloons in the sky. The sites along the east coast are launching  them every 6 hours. The map shows you the sites with the two extra launches per day.
