Frank's Weather or Not: 600 Even! Why so many Tornadoes?


HOUSTONPhoto from Charles City, Iowa last Sunday from the brother of my friend Andrew Cordes!

As I write this, the month of May has recorded 600 Tornado reports across the United States! Compare that to the US average of 276 tornadoes in the month of May and we're at DOUBLE the normal for the month. Here is how it has broken down so far:

124 Tornado reports from May 1 to May 9.

3 Tornado reports May 11/12

473 Tornado reports May 16 - 29.

That's a two week stretch of tornadoes! These are reports and the NWS has not confirmed all of them were tornadoes, but the year now holds the record of 14 days in a row of tornadoes beating the 11 days in 1980. The Storm Prediction Center for today targets the northeast US for possible tornadoes.


Thursday's Severe Weather Threat

The set up is changing as the Jet Stream finally flattens to a more zonal flow across the U.S from what we have been seeing:


The Jet Stream will flatten out by Saturday:



and that will help but the overall pattern for June remains the same:


NWS 30 Day Outlook for June

On the left is the temperature forecast and BELOW normal, or cooler, is forecast from North Texas to South Dakota while Above Normal precip is forecast in the graphic to the right. Bottom line: already flooded areas along the Arkansas River in Oklahoma will continue to struggle against flood potential.

On another note, Hurricane Season officially begins Saturday. If there is any good news, the next week shows no tropical development in the Atlantic basin.
