A squall line.
squall line is a group of storms arranged in a line, often accompanied by “squalls” of high wind and heavy rain. Squall lines tend to pass quickly and are less prone to produce tornadoes than are supercells. They can be hundreds of miles long but are typically only 10 or 20 miles wide.
Thunderstorm Basics What is a thunderstorm?
A thunderstorm is a rain shower during which you hear thunder. Since thunder comes from lightning, all thunderstorms have lightning.
Why do I sometimes hear meteorologists use the word “convection” when talking about thunderstorms?
Usually created by surface heating, convection is upward atmospheric motion that transports whatever is in the air along with it-especially any moisture available in the air. A thunderstorm is the result of convection.
What is a severe thunderstorm?
A thunderstorm is classified as “severe” when it contains one or more of the following: hail one inch or greater, winds gusting in excess of 50 knots (57.5 mph), or a tornado.
How many thunderstorms are there?
Worldwide, there are an estimated 16 million thunderstorms each year, and at any given moment, there are roughly 2,000 thunderstorms in progress. There are about 100,000 thunderstorms each year in the U.S. alone. About 10% of these reach severe levels.
When are thunderstorms most likely?
Thunderstorms are most likely in the spring and summer months and during the afternoon and evening hours, but they can occur year-round and at all hours.
Along the Gulf Coast and across the southeastern and western states, most thunderstorms occur during the afternoon. Thunderstorms frequently occur in the late afternoon and at night in the Plains states.
What kinds of damage can thunderstorms cause?
Many hazardous weather events are associated with thunderstorms. Under the right conditions, rainfall from thunderstorms causes flash flooding, killing more people each year than hurricanes, tornadoes or lightning. Lightning is responsible for many fires around the world each year, and causes fatalities. Hail up to the size of softballs damages cars and windows, and kills livestock caught out in the open. Strong (up to more than 120 mph) straight-line winds associated with thunderstorms knock down trees, power lines and mobile homes. Tornadoes (with winds up to about 300 mph) can destroy all but the best-built man-made structures.
Where are severe thunderstorms most common?
The greatest severe weather threat in the U.S. extends from Texas to southern Minnesota. But, no place in the United States is completely safe from the threat of severe weather.
What is the difference between a Severe Thunderstorm WATCH and a Severe Thunderstorm WARNING?
A Severe Thunderstorm WATCH is issued by the NOAA Storm Prediction Center meteorologists who are watching the weather 24/7 across the entire U.S. for weather conditions that are favorable for severe thunderstorms. A watch can cover parts of a state or several states. Watch and prepare for severe weather and stay tuned to NOAA Weather Radio to know when warnings are issued.
A Severe Thunderstorm WARNING is issued by your local NOAA National Weather Service Forecast Office meteorologists who watch a designated area 24/7 for severe weather that has been reported by spotters or indicated by radar. Warnings mean there is a serious threat to life and property to those in the path of the storm. ACT now to find safe shelter! A warning can cover parts of counties or several counties in the path of danger.

Awesome! Nothing like a good storm to make you feel insignificant. ;-) Good luck on your move and selling your old home. Too bad We didn't get to meet up at Hamvention this year.
Yeah I wasnt going to go anyway. Our move has stressed me out. We had 2 offers and both backed out. Very hard
Yes, moving to Oklahoma will give you many storm chasing opportunities. Good luck.
Thanks, we enjoy it.
Those lines developed just east of our area and continued across the state to your side. Was very cool for us spotters for sure.
What's your area? I watched Reed Timmer drive around Pryor OK where my family is originally from liveatream earlier
@@hamradiocq This is KEORPU. I live west of you about 250 miles in you sister city.
I hope you and your family are safe and well during the move and quarantine.
Thanks Randy.

These are so uncommon at Melbourne Australia but a month ago when I was at school there was a low as one, the wind picked up and it was pouring like crazy. Our squal line was way smaller though it lasted around 9 minutes.
