Lack of 2013 Tornadoes Continues Sep 5, 2013

I don’t know about you, but I feel like I’ve barely seen any storms close to home this summer. According to the SPC, there have been quite a few less tornadoes this year than in years past. Spotty storms earlier this week produced several storm reports including hail, damaging winds and flash flooding. Thanks to Megan Payne for the picture below out of Lakewood, NY.

Damaged Pumpkins in PA

Heavy rainfall in Columbia county, PA earlier this week was responsible for sweeping away these pumpkins from a pumpkins field. It appears that they were deposited in someones backyard.

Midwest Lightning

A cool front swept through the Midwest over the weekend with additional showers and storms, which was responsible for a tornado report out of north-central Illinois on Sunday, September 1st. That same front kicked out some wicked lightning near Mount Vernon, IL Saturday night. Thanks to DJ Derve for the picture below.

Western Storms

Monsoonal thunderstorms continue to pop up in the West. Tropical moisture has been getting tangled up in this flow, so we’ve actually seen several flash flooding reports over the past several days. Thanks to @youtah for the incredible lightning picture below out of Salt Lake City, UT.

Western Flooding

Take a look at the image below out of Palm Springs, CA. Heavy rainfall was responsible for this massive debris flow. This is something that you definitely don’t want to get tangled up with.

Early September Severe Climatology

I thought this was interesting. When comparing the severe weather chances at this time of the year vs. the middle of May, there is a pretty stark contrast. Generally, severe thunderstorms at this time of the year are a lot less than that of May.

Tornadoes This Year

Here’s another interesting map. The line indicates the average number of tornadoes by month for the U.S. while the solid colors indicate the actual/preliminary number of tornadoes that have been reported so far this year by month. If you look at it closely, you can see that we started 2013 off with a bang. Both January and February were above average for the month, but after that we’ve been consistently below average, including May, which is typically the most active month for U.S. tornadoes.

May 2013 Tornadoes

Because the image above was a little hard to read for the month of May, here are the actual May numbers, note that we ended May with a slightly below average number.

2013 Tornadoes Comparison

According to the SPC, 2013 has been a VERY quiet year for tornadoes. When comparing 2013 to the past 2 years, it is significantly different than 2011 by nearly 1,000 reports!!

2013 Tornadoes vs. Average

According to the SPC thru September 3rd, there have been 725 PRELIMINARY tornado reports, which is significantly lower than the average thru that date (1,277). In fact, if you look closely at the image below, this is the lowest number of tornadoes that we’ve seen in the 2005-2013 preliminary tornado count thru that date.

Thanks for checking in and have a great weekend ahead!
