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:

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 3… Hurricane Sprites/Extra Launches/Northern Lights/October Normals

Something strange this way comes… or shows up on a far away camera from a hurricane.

Hurricane Matthew is churning through the Caribbean,producing tons of rain with winds of 130 mph as it tracks to the north. On Saturday, it also produced a phenomena that is rarely caught on camera…. sprites!

Sprites are essentially lightning bolts that go out the top of a thunderstorm. They are usually weak and not often seen and are usually a red color.  They last a very short time and are hard to catch on camera. Which is why the fact that at least 28 of them were caught on camera on Saturday is an amazing feat!

There is a little more from The Weather Channel at this link.  More color photos on another post from The Weather Channel are here.

With the first Monday in the books, let’s look at the October averages and extremes for the month.

Every 12 hours certain National Weather Service offices around the country send a balloon (radiosonde)  in the sky to gather valuable data. The stars on the map below show where the balloons are launched from.

After the data from the balloon is sent back to the office it is then put into computers to help with the forecast.  The idea is, the more current and reliable data you get into the calculations, the  forecast output (forecast information) would be closer to reality. Now because of Matthew, a large hurricane forecast to run up the east coast this week, they are putting more balloons in the sky. The sites along the east coast are launching  them every 6 hours. The map shows you the sites with the two extra launches per day.
