ICYMI Oct 24 – World Record Temp/Hole Punch Clouds/Seymour

The world record high temperature of 134 degrees was set in Death Valley (Furnace Creek), CA on July 10, 1912 …but did it?


There has been research as to the validity of the report. Back in February of 2013, there was a paper published showing, what was through to be the world record (136° in northern Libya), the reason why that record was no longer a valid record.

This would now make the 134° report at Death Valley the world record. Well…not so fast. Click here and take a look at some research that has been done on that temperature reading just posted. As of now 134° is the record. We will wait and hear from the World Meteorological Organization (WMO) says about it.


Hole Punch Clouds and Sundog


Hurricane Seymour (Cat 2 storms) is in the eastern Pacific Ocean Monday afternoon and forecast to strengthen. At this point the forecast keeps it away from land.

ICYMI Oct 9….First Frost/Matthew now post-tropical/Earthquake/Fall Foliage

When is the typical first frost in eastern Iowa?

First Frost Dates

Well…we’re well past that date for many. The past two nights (Friday and Saturday nights) have been the coldest since the spring time. “Frost” refers to when temperatures fall into the mid 30s…causing some frost on plants/crops. “Freeze” is when temperatures fall below the freezing point of water (32°F). We’ve received reports of frost this weekend but some warmer air is on the way the next few days.

For more information on frost and freeze in Iowa, click here.

The once hurricane Matthew is now post-tropical cyclone Matthew. At the time of the change, Matthew still has hurricane force winds. The difference is simply in the structure of the storm. A more in depth explanation of tropical vs post-tropical cyclones can be found here.

There were 3 earthquakes recorded less than 300 miles off the Oregon coastline today.  Fortunately, tsunami warnings were not issued.

Three earthquakes with magnitudes ranging from 4.1 to 4.8 occurred several hundred miles off the Oregon coast on Sunday, but none triggered tsunami warnings.
The U.S. Geological Survey says the 4.8 quake was recorded last and occurred at about noon about 260 miles west-northwest of Coos Bay.

You’ll notice more vibrant colors on the trees as we go through the next few weeks, as many areas across eastern Iowa are reaching peak Autumn color.

ICYMI Oct 8…Hurricane Matthew/Chilly Start/Fall Leaves

Hurricane Matthew continues to dominate the headlines in the weather world.  The storm made an official landfall at 10 AM southeast of McClellanville, South Carolina as a Category 1 hurricane with sustained winds of 75 mph.  It’s been more than 12 years since South Carolina has had a hurricane make landfall.


Here’s the latest forecast from the National Hurricane Center.


Closer to home here in eastern Iowa, it was a CHILLY start, with temperatures in the 30s.  Some of our Weather Trackers reported frost early this morning.


Saturday night will be another cool one with upper 30s to lower 40s for overnight lows.

With the longer, cooler nights, leaves will continue to change color.  Here’s a photo from a viewer that was taken Saturday afternoon.

ICYMI Oct 2…Fall Foliage/Hurricane Matthew/Weather Balloons

The first weekend of October is behind us, and now that the daylight hours are getting shorter and the nights are getting cooler, we are starting to see some color on the trees.


Within the next few weeks, we will see an increase in vibrant colors across eastern Iowa as the leaves on the trees continue to change color, and eventually fall.  Here’s the peak fall foliage across Iowa, courtesy of the Iowa Department of Natural Resources.


If you have any fall photos you’d like to share with KWWL this season, feel free to send them our way.

Our friends along the eastern seaboard (and weather enthusiasts across the country) are keeping a close eye on Hurricane Matthew, which continues to slowly move through parts of the Caribbean Sea.  As of Sunday evening (10/2), Matthew is a Category 4 hurricane with winds of 145 mph.  The trend has been for the storm to weaken a bit, then reorganize the eye and strengthen shortly after.  This is pretty typical for strong hurricanes.  National Hurricane Center forecast is fore Matthew to track slowly to the north, with major affects on Jamaica, Haiti, Cuba and the Bahamas early in the week.

HUIR Later in the week as the hurricane tracks north, it may indirectly impact Iowa, by slowing down the flow of the atmosphere, similar to Hermine last month.2015 Tropics

Each day National Weather Service offices across the country send up a “weather balloon”, which has a radiosonde attached the measures various weather parameters at different levels of the atmosphere.  These are sent up twice a day; 7 AM and 7 PM; and the information gathered by these balloon launches are then put into the numerous computer forecast models.  Several NWS offices near/along the east coast are sending up balloons every few hours to get a grasp on where Matthew will track, and how strong the hurricane will be.  Here’s a picture of one of those launches Sunday afternoon, from the National Weather Service office in Key West, Florida.

ICYM- Sept 18….Sunrise/Fall Foliage/River Flooding

The sky was mainly clear Saturday night, allowing for a great sunrise across eastern Iowa.  This was taken in Waverly.

That nice sunrise lead to a day with lots of sunshine.  Southwest winds, along with the sunshine, pushed temperatures into the 80s Sunday afternoon.  Despite it feeling like summer, some viewers caught signs of fall this afternoon.

Fall officially begins this Thursday (September 22nd), so we will be seeing more shots like the ones above in the days and weeks ahead.  We start noticing a peak north of Highway 20 beginning the last week of September (on average).  Click here to learn more about leaves changing color in the fall, from the IOWA DNR.


Recent heavy rains have continued to impact area rivers.  The Cedar River at Cedar Falls and the Iowa River at Marengo have flood warnings.



Our weather pattern turns a bit active this week, as a frontal system stalls out.  As of now, it looks like the heaviest rain falls in parts of northern Iowa and southern Minnesota.

ICYMI- Sept 15….Typhoon Meranti/Strong Storms

Super Typhoon Meranti made landfall in China today. It is a well formed typhoon with a very tightly closed eye.

Typhoon Meranti

More images can be found here.

The same typhoon caused the Moon to roll through Fuzhou, China:

It is actually a balloon for the The Mid-Autumn Festival. It was ripped free by the strong winds of Super Typhoon Meranti. Peak winds were as high as 190 mph at times as it tracked through the Northwest Pacific.

Closer to home, storms began rolling in after 7PM.  Here’s a view from KWWL viewer Jeff Coen, just west of Cedar Falls.


As those storms moved through the Waterloo/Cedar Falls area, several viewers reported some small hail, along with the heavy rain and gusty winds.  The Waterloo Airport had a peak wind gust of 61 mph at 8:03 PM as the storms rolled through.

Jesup had a wind gust reported in at 50 mph at 9:48 PM.

ICYMI – Sept 14…Julia/Pacific Typhoons/Sunrise/Sunset

Tropical Storm Julia formed Tuesday night over land near Jacksonville, Florida, and continues to bring very heavy rainfall and flooding to parts of the Florida, Georgia and Carolinas coastlines.  It isn’t forecast to move much over the next couple days.


Meanwhile, the western Pacific Ocean is  fairly active.  Typhoon Meranti made landfall on the island of Jinmen near Xiamen, China with sustained winds of 145 mph.  Prior to making landfall in China, the powerful typhoon slammed parts of Taiwan, when the storm was packing 230 mph winds.

Another typhoon, Malakas, is on its heels.  As of Wednesday evening, the winds were 90 mph, but the typhoon is expected to strengthen over open water.   Eventually, the storm is supposed to track between Taiwan and the Yaeyama Islands of Japan around Saturday.  Click here for the latest satellite loop.


It was a quiet day across eastern Iowa with a mix of clouds and sun.  More clouds were found earlier in the day.   Here is a viewer photo of the sunrise, and another of the sunset.

ICYMI – Sept 13…Rocky Road/ Magnetic Putty/ Tornado Scar/ Super Typhoon

After several weeks of heavy rainfall, with only a few breaks in between, the latest round of storms may have proved too much for a boulder near Marquette. The Iowa Department of Transportation posted these photos on their Facebook page this morning.  The road was completely closed for an hour or so as crews worked to move the huge rock. As you can see, it was almost as large as the tractor they were using to move it.   The tree took a tree with it to help block the road.

ICYMI-Sep 11… Cool Temps/Flooding/Remembering 9-11-01

It was a pretty chilly start to Sunday, with temperatures in the upper 40s to lower 50s, just slightly below average.

Heavy rains late last week has once again lead to a rise in area rivers in northeast Iowa.  Flood Warnings continue for the Cedar River at Cedar Falls, and the Turkey River at Elkader and Garber.

Today was a day to reflect, as it’s been 15 years since the terrorist attacks in New York, Washington, D.C., and Shanksville, Pennsylvania.  Several KWWL viewers sent in photos of flags being displayed, including this one at the Decorah Fire Department, sent to us by Kurt Hageman.  The red, white and blue really stood out against the clear, blue sky.
