Veterans Day Severe Weather

There were 11 reported tornadoes across the state of Iowa. As of Thursday 6:00 PM (Nov. 12th), 7 tornadoes have been confirmed, and the information is subject to change upon further review.

Confirmed Tornadoes on Map

It was an active Veterans Day across the Midwest, as a strong area of low pressure tracked through, bringing rain, severe thunderstorms, a few tornadoes, and even snow. Fortunately, there were no reports of any tornado touchdowns in the KWWL viewing area.

Here are the preliminary storm reports from the Storm Prediction Center:

The National Weather Service in Des Moines confirms an EF-0 tornado touched down in Guthrie County:

NWS Des Moines also confirmed an EF-1 tornado in Marion County:

Another tornado confirmed by the Des Moines NWS – an EF-1 in northern Mahaska and southern Poweshiek counties, just outside the KWWL viewing area:

There was also a tornado spotted at the Des Moines International Airport:

The strongest of the confirmed tornadoes was an EF-2 in Monroe and Appanoose counties:

National Weather Service in the Quad Cities confirmed an EF-1 tornado in Scott County. This was unique, because it formed ON the Mississippi River (debunking the myth that rivers protect certain cities from tornadoes):

Another EF-1 tornado was confirmed in Avoca, Iowa (Pottawattamie County) by the NWS in Omaha Nebraska:

Here’s a YouTube video of that tornado.

As mentioned, there were no tornadoes reported in the KWWL viewing area, but there were reports of damaging wind.  Here is a picture of a barn that was picked up and taken by the damaging wind on 12th Street in Cedar Falls:

Damage was also done to Pat & Tami Paisley’s farm in Balltown (Dubuque County):

Here’s a photo of damage to a trampoline in Tatiana Schroeder’s yard in Key West (Dubuque County):

Here’s another YouTube video of another severe thunderstorm rolling through southeast Iowa:

There were two sides to the system: A warm side (relative to November standards), and a cold side.  There was a report of a tornado  at the Des Moines International Airport around 3:35 PM.  Once the low pressure and cold front passed through, there was a rain/snow mix reported several hours later.  That shows how dynamic and powerful this storm system was.
Here is the radar at the time of the tornado (around 3:36 PM), and the mix (around 10:06 PM):

Severe Weather in November

You typically don’t think of November as a big severe weather month. Usually April, May and June are the prime months. If the conditions are just right severe weather can happen at any time of the year. There is a chance of severe weather Wednesday in the middle of the country. It has been 2 years (11/17/13) since there was this strong of a threat for severe weather.

EF-0 Tornado Tuesday

The National Weather Service (NWS) rated the tornado near Stanwood Tuesday afternoon an EF-0. The Quad Cities NWS radar was down at the time of the tornado so no data was available. The NWS survey team went to the area see if there was any damage…they saw no damage in the area.  A storm chaser took video of the funnel cloud/tornado. The chaser said it touched down briefly and because of that the NWS gave it a low end EF-0 rating.

Wet Microburst in Tucson, AZ

A textbook wet microburst was recorded Saturday in Tucson, AZ. The time lapse shows the tremendous amount of rain and wind crashing into the ground. When it does that, it spreads out and could cause significant damage in a small area.
