No Tornadoes In Oklahoma Or Kansas In 2018

Good morning bloggers,

We will discuss another incredible record that is about to be broken later this week on this rainy Sunday morning. But, first, take a look at radar:

Kansas City is on the northern edge of the comma head of this storm. The storm ended up falling right into place southeast of Kansas City, and the comma head of rain finally backed into the KC metro area this morning. It was moving west in the cyclonic circulation:

There was a rather well defined north and west edge, so many areas will stay dry, if you live up north. On the south side of the metro, it is a nice area of rain spinning west around the circulation, but amounts will still be fairly low. KCI Airport was still sitting at 4.68″ for the year, which is way below the average of 7.45″ by todays date.

This cooler pattern has lead to an interesting tornado statistic:


Weather.com posted an article discussing this record that is about to be broken, and here is what they discussed and suggested is the reason:

Since 1950, however, there has never been a year with zero tornadoes recorded from January through April in Oklahoma. The National Weather Service in Tulsa noted earlier this week that the record for the latest start to the tornado season is April 26, which occurred in 1962.  With generally cooler-than-average temperatures expected, conditions through the end of the month do not look particularly favorable for tornadoes in Oklahoma, so a new record looks very likely.

One reason for the lack of tornadoes and severe weather this year has been the persistent upper-level pattern in place. This pattern has brought a southward dip in the jet stream to much of the central U.S., which has allowed colder-than-average conditions to dominate these regions.

Or, they could just say “the LRC”.  And, then they go on into something that isn’t quite right, “The combination of colder temperatures, less moisture and a more northerly storm track have resulted in fewer severe thunderstorms and tornadoes through mid-April.”  Actually, the storm track has not been more northerly. If this were the case, then this would not be a cold pattern. It isn’t that the storm track is farther north, but that the center of the driest region over northwestern Oklahoma into the Texas Panhandle has been near the quasi-permanent anchor ridge this season, as proposed in the peer reviewed paper.  This pattern will continue, but as temperatures warm up, there will be increasing chances for some severe weather over Oklahoma.

Now, add this statistic to this record. Kansas has not had a tornado either. There hasn’t been one tornado in Kansas or Oklahoma yet in 2018.  Kansas averages around 12 by now.

Thank you for sharing in this weather experience featuring Weather2020 and the LRC. Join the conversation over on the blog at Weather2020 and we will look ahead in tomorrows blog.
