Winter Outlook 2017-2018

The National Oceanic and Atmospheric Administration (NOAA) has released the 2017-2018 winter outlook.  Right now, a La Niña pattern is setting up.  This means that the waters of the Pacific Ocean, near the Equator, have colder than normal temperatures.

So, what does that mean in Iowa?  NOAA is predicting that portions of eastern Iowa have a chance of above average precipitation, whether that is in the form of rain or snow.

As for the temperatures, we have equal chances of a colder than average, warmer than average, or “average” winter.  This basically means there are no strong signs pointing one way or the other.

The bottom line here — yes, we will have cold and we will have snow.  Also, expect some bouts of warmer temperatures, and some bouts of very cold temperatures.  After all, it is winter in Iowa.

October Rainfall (So Far…)

With October being almost halfway done (can you believe it?), portions of eastern Iowa have already received their average monthly rainfall totals (and then some).  Meanwhile, others haven’t had quite as much as the average monthly totals, but are on course to meet them as we head into the second half of the month.

As you all know, it was a dry second half of summer into the first part of fall.  We took a look back at our current October rainfall (through October 12th), and found out how many days prior to this month, did it take to receive the amount of rain we’ve received in the first 12 days of the month.  Here’s what we found.

There is more rain in the forecast as we head into Friday and Saturday.  Rainfall totals across the KWWL viewing area will be between 0.50″ in northwestern portions of the area, to 2.00″ in eastern and southeastern portions of the area.

July 2017 Review

July was all about the haves and “haves and have nots” when it came to rainfall.  The map below shows the departure from average July rainfall for 2017.  Notice, northeast Iowa received several inches more rain than usual.

Here are the statistics from Waterloo, Dubuque, Cedar Rapids and Iowa City.

90 Degree Days

Hot and very humid weather is expected through Saturday. Some locations will top 90 degrees a few times this week. I took a look back at how many 90 degrees we have had so far this year and compare that to previous years. At a quick glance, 2012 was hot through the middle of July.

Through July 18th, Waterloo has reached 90 or warmer nine times while Dubuque has only done it two times. Cedar Rapids came close today with a high of 89….so far this year it is eitght days. Today was another day of 90+ for Iowa City with a high of 92. That now takes the number of days of 90 or warmer to 18.

ICYMI Nov 1 – Halloween Storm of ’91/Halloween Normals/Scary Space/November Preview

Yesterday marked the 25th anniversary of the 1991 Halloween winter storm. Some recorded a dusting while many in northwestern Iowa saw over 10 inches by the time things were said and done on November 2nd.

For more information, visit the Des Moines National Weather Service.


 

High temperatures today are more like the middle of September than the beginning of November.

The first five days of November this month are expected to be warm, but not as warm as they were last last year. The chart below shows the high temperatures for the first five days of November last year compared to the forecast this year.

The night sky can be beautiful here in eastern Iowa. But beyond what we can see, it can be a little creepy. NASA’s Exoplanet Exploration looks at what planets outside of our solar system are like…some are not so pleasant.

November is here and normally things start to get really chilly this month. Here’s a look at November by the numbers in Waterloo and Dubuque:

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.
