Regional Outbreaks of Severe Weather Through Early Next Week; Early Season Heat Wave across the South

Active spring pattern across the center of our nation with several episodes of severe weather and heavy rainfall expected into next week. The potential for very large hail, long track tornadoes, severe wind gusts, frequent cloud to ground lightning strikes and flash flooding are in the outlook. Furthermore, dangerous early season heat wave continues for the Gulf Coast states into early next week. Read More >

Image of a weather balloon, and a mapping of where the balloons have tracked in 2024 (as of September 3rd)

 

We recently made a social media post on Tuesday about our morning weather balloon, and there were a couple inquiries about where they go.

Using a website called SondeHub (www.sondehub.org), which tracks the type of instrument packages we use via local receivers, we plotted the last known location for each of our weather balloons this year. In this image, the cooler shades (blues) show locations closer to the ground, while the warm (red/orange) shades are fairly high up and show more uncertainty. Why? The balloons typically pop at a height over 100,000 feet, and the instrument package (which is quite light) does not drop straight down and remains subject to the winds aloft.

The distance traveled will depend on the steering winds aloft, which tend to be stronger in the winter and lighter in the summer. However, typically they will land in either central or eastern Illinois, or western Indiana. The farthest one this year appears to have traveled to the northeast corner of Indiana north of Fort Wayne.
