Recent Wild Weather
On August 25th, in Des Moines, IA, pillows of clouds were seen stretching across one highway. This phenomenon is known as a gravity wave and was caused by storms in northern Iowa. Gravity waves are waves in the atmosphere and happens when air rises and falls in a stable layer of the atmosphere. Regions with upward-moving air create rows of low-hanging clouds. At a local news channel, these ripples could be seen on their radar. 45 minutes after storms rolled in, an outflow boundary was seen on the radar. Within half an hour later, many outflow boundaries could be seen, which is what caused the gravity waves to appear.
Wild Weather this Day in History
On August 30th, 1838, Rhode Island was hit by a major tornado, one of the worst in the states recorded history. The tornado struck around 3 o’clock in the afternoon, so many people were out and about. Increasing rapidly to a size of 600 feet wide and causing a path of destruction 25 miles long, this tornado uprooted trees, destroyed many homes, sucked water out of ponds, and injured 5 people. Luckily, this tornado managed to avoid hitting a local railroad department where many people were waiting for the train.
Have an amazing rest of the week and continue to enjoy these warm sunshiny days!
