November Tornadoes….Again

Yes, it happened again…tornadoes in Iowa during the month of November. Last year, on November 11th, there were 19 tornadoes in Iowa. The map below shows the tornadoes from November 2015.

Click here for more details on the tornado outbreak last year. Since 1980, there have been 41 tornadoes and it looks like that number will go up after Monday afternoon.

Here is a look at the funnel cloud or tornado reports from Monday afternoon as a cold front pushed slowly across the state.

ICYMI Nov 27…Nebraska Tornado/Spain Waterspout/Snow Depth/Tis The Season

While it doesn’t happen often, tornadoes CAN occur in November across the Midwest, and even here in Iowa.  A few tornado warnings were issued earlier Sunday evening in Nebraska.

Below is a screenshot of a video taken by a gentleman living in Minden, Nebraska.  Click here to view the video on Twitter.  You can see it’s a “rope” tornado.

As mentioned, it doesn’t happen often, but it’s not impossible to see a tornado in Iowa during November.  Since 1980, there have been 41 tornadoes reported in our state.

Across the pond, there was a waterspout spotted off the coast of Spain.  See the video below:


Switching gears to snow.  Last year at this time, 34.5% of the United States was covered in snow.  This year (as of November 27th), 15.4% of the U.S. is covered in snow.

Here in Iowa, it has been a dreary Sunday evening.  Despite the rain, it looks pretty festive with the lights in downtown Waterloo.

A magnitude 5.0 earthquake occurred in central Oklahoma near the city of Cushing Sunday evening at 7:44 PM.  The earthquake was initially reported as a 5.3, before the USGS downgraded to a 5.0.  The Cushing Police Department has reported “quite a bit of damage” following the quake, however there has been no reports of any injuries as of Sunday evening.

As we get later and later in the fall season, we are seeing less and less trees with leaves across Iowa.  Here are a couple photos sent in by viewers this weekend.  If you even have a photo you’d like to share, you can post them on our KWWL Storm Track 7 Facebook and Twitter pages, or e-mail as at weather@kwwl.com

ICYMI Oct 16 – Indian Summer?/Antares Rocket/Oregon Tornado

It will be abnormally warm tomorrow here in eastern Iowa. During this time of year, people start to bring up the term “Indian Summer”. But to have a true Indian Summer there are certain qualifications that need to be met:

Indian Summer

Unless you saw a killing freeze late last week, this will not be a true Indian Summer – but enjoy the warmer weather nonetheless!


As we mentioned on Oct. 15th, the Orbital ATK Antares Rocket was set to launch from Wallops Island, VA this evening, taking 5,100 pounds of supplies, science research and vehicle hardware to the International Space Station.  Well, that launch has been set back about 24 hours, and is now scheduled to launch on October 17th at 6:40 PM our time.  This delay is due to a glitch with ground support equipment.  Click here to learn more about the rocket launch.

A rare, Oregon tornado was confirmed in the morning on Friday, October 14th by the National Weather Service in Portland, Oregon.  The tornado was rated and EF-2 with winds of 135 mph.

The tornado began over the Pacific Ocean as a waterspout, and moved on land causing damage.

ICYMI Sept 19…Antisolar Rays & Belt of Venus /90° Days/Baseball Sized Hail

Severe storms were in the forecast for this afternoon and evening, but little to nothing materialized. The reason for that is because of what is called a CAP. This is small layer of the atmosphere that is warmer and it prevented the air from rising quickly.

___________________________________________
The high temperature today was 89 degrees in Cedar Rapids. I went back and looked to see how often does a high temperature of 90 degrees get reached in September at Cedar Rapids. Well, on this date is has done eight times. The chart below shows the calendar day at the bottom and temperature on the left. Each bar shows the number of days the temperature reached 90 or higher on that particular day. So again, on the 19th it was 90 or warmer 8 times on that day. Notice how fast the frequency drops off toward the end of the month…not very often.

There is a great web page very interesting photos and descriptions of why things look the way they do. Les Cowley puts off of this information on the web page. There is a section called Optics Picture of the Day. I learn something new every time I go the web page. The photo is just one example of some great photos on there. Here is the link.

ICYMI- Sept 16….Comet Breaks Up/Tropics/Lightning Strikes

It’s not you, it’s me.  The breakup of a comet

hubblecometvideogifv1635a332p160831-1041

Over a three day period in January of this year, Hubble Space Telescope took pictures of a comet breaking up a mere 67 million miles from Earth.  There is still plenty of material for the comet to last another few trips around the sun, but these images are giving insight to the violent forces that can tear comets apart as they approach the sun.  One of the paragraphs from the main article (which you can read by clicking here):

The observations suggest that the roughly 4.5-billion-year-old comet, named 332P/Ikeya-Murakami, or Comet 332P, may be spinning so fast that material is ejected from its surface. The resulting debris is now scattered along a 3,000-mile-long trail, larger than the width of the continental U.S.

##############

Another tropical storm has formed in the Atlantic. This one is named Karl and is forecast to become a category 1 hurricane by Wednesday. The good news is that models are keeping Karl away from the US coast.

A group of experts from the World Meteorological Association released two new world records regarding lightning.  One is the longest reported distance for a single flash of lightning, and the other is for the longest duration for a single flash of lightning.  As you can see, the longest duration happened in France, and the longest distance happened in Oklahoma.

“Dramatic improvements in lightning remote sensing techniques have allowed the detection of previous unobserved extremes in lightning occurrence and so enabled the WMO committee to conduct a critical evaluation.”  View the entire article by clicking here.

Speaking of lightning, The Des Moines Register reports a bolt of lightning struck the clock on top of the Polk County Courthouse in Des Moines around 3:50 AM Wednesday.

The clock is expected to be fixed “very soon.”

Tornado Near Cresco Tuesday Evening

A strong storm was producing 40-45 mph winds in Howard County Tuesday evening. The video below also shows a short lived weak tornado.


Here is the velocity image from the radar this evening where the tornado might have been. The red area is moving away from the radar and the green is moving toward the radar. This image would indicate the tornado between Lime Springs and Cresco in the outline circle.
