ICYMI Oct 19 – Warmer Days/Meteor Shower/Record Temps

Cooler weather Thursday and Friday does not last long. Warmer weather returns for the weekend and may continue through early November.


A clear sky Thursday night/Friday morning allows us to see Orionid meteor shower. It is forecast to peak late in the evening into early morning hours of Friday. Click here for more details.



High temperatures Monday were warm. They were so far above normal in parts of eastern Iowa we have to go back to early March.

ICYMI Oct 17 – Warm/Hurricane Nicole/Launch

It felt more like summer than the middle of October across much of the nation. There a few records in Iowa today. Iowa City tied the record high temperature of 88 set in 1950. Other records broken were in Des Moines 87 (previous record 86 in 1950) and Burlington 89 (previous record 87 in 1950).
Record Highs vs Actual

Dodge City, KS had a temperature of 100 degrees.



Still churning to the north, hurricane Nicole is moving through the Atlantic Ocean. It is tied with “Lester” for the longest lived named storm of 2016 in the Northern Hemisphere. Nicole is the longest lived Atlantic tropical cyclone to form in October since 1932 – with a lifetime of 13 days. The last time a hurricane reached north of 40°N, like Nicole is now, was hurricane “Gonzalo” in 2014.

ICYMI Oct 12- 32 Degrees/Global Precipitation/Hurricane Nicole

Here is a look at how many days the temperature has been 32° or colder in September and October at Waterloo.


A look at global precipitation… images taken every 30 minutes… including Hurricane Matthew as it churned up the East Coast. Check out the link here.

Hurricane Matthew is now a storm in the past, as millions clean up from Haiti up to the United States.  Hurricane Nicole continues to churn in the Atlantic Ocean, as a major Category 3 hurricane (as of Wednesday evening), and is forecast to hit very close to the small island nation of Bermuda sometime on Thursday.

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 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.


Here is a look at how much rain has fallen so far this month across Iowa.


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.


On September 18, 2002 a storm producing baseball size hail with wind gusts to 70-80 mph in Jackson County. Click here for more details on this event.

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.

Latest Drought Conditions

The latest U.S. Drought Monitor was released Thursday morning, and parts of Iowa are experiencing an Abnormally Dry to Moderate Drought.  Most of the KWWL viewing area, especially across the north, have had plenty of rainfall in recent weeks.

Drought Monitor

This taken into account the precipitation that feel between July 5th and July 12th.  Fortunately, some of those areas in southern Iowa have received at least a little bit of rain from the storms that tracked through Wednesday afternoon.

KWWL 2015 MAX Storm ED

Next week, a ridge builds across the center of the country, and that brings in hot weather.  Several days are expected in the 90s, and aside from a chance for rain Saturday night and Sunday, we are looking at a mainly dry weather patter.

First 90° Temperatures of the Season Possible This Week

If you are a big fan of summer-like temperatures, you are going to like the forecast for late in the work week and into the weekend.

First, the start of the week will feature near normal, or below normal temperatures.  A warm front tracks through on Thursday, bringing warmer temperatures and higher humidity levels.  Many of us in eastern Iowa could reach 90° or hotter by Friday.  Here’s the last time it was at least 90°, back on September 6, 2015.

Avg First 90 Deg Day - 4 Lines

Our first potential 90° days this year, are coming at the same time as the first 90° last year.

90 2015


It’s pretty typical to get our first 90° the last week of May into the first two weeks of June, climatologically speaking.  (Photo from The National Weather Service)



Looking at the forecast, warmer than normal conditions are likely from June 11-June 15.

Local pools will be busy!

A Chilly May…so far

It hasn’t been the warmest of days lately. The last time Waterloo had high temperatures near normal was May 8. We had just one day with temperatures above 75° and it was 87°. The 87° reading is also the warmest temperature so far this year. Through May 15th, the average monthly temperature at Waterloo is 3.8° below normal. The chart below shows the high temperatures (red bar) and the low temperatures (blue bar) for the month of May through the 16th. The pink dots are the normal highs for that day and the light blue dots are the normal lows for that day as well.


The map below, issued at the end of April, shows the temperature outlook for May. In eastern Iowa there was a low chance of above normal temperatures.

The 6-10 day outlook (below) issued today,  for May 22-26, shows above normal temperatures are likely. High temperatures get back into the 70s Saturday and close to 80 Sunday and Monday.

Cold Sunday Morning

It’s feeling more like late October or late March across eastern Iowa this weekend. Lows Sunday morning across eastern Iowa were in the lower to middle 30s, with some outlying areas reaching the upper 20s.

DMA Low Today3D

Waterloo and Dubuque both tied their record low temperatures of 32° (2004 and 1997, respectively).  The temperature in Cedar Rapids and Iowa City were within one or two degrees of reaching the record low.  Those record, which date back to the 1920s, still stand.

Record Lows vs Actual

If you’re not a fan of this unseasonable cold weather, there is good news.  We are looking to warm things up the second half of May.
