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.
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.
Here is a view of Hurricane Matthew Monday from the International Space Station (ISS). The ISS is 250 miles above the storm. Below is the video as the ISS passes over the hurricane. (video speed 4x)
No doubt about it….it has been a warm December. As we get closer to the end of the month I thought I would take a look at some of the numbers for Waterloo. The chart below shows the average temperatures, for December, from 1950. On the right side of the chart there is a list of the top 10 warmest Decembers on record.
Here is a break down of the number of degrees above and below normal each day so far this December for Waterloo, Dubuque, Cedar Rapids and Iowa City. Notice most days we were 10-20 degrees above normal for the day.
The temperature outlook through the rest of the month is above normal. So the way it looks right now, we won’t have a problem reaching the record.
I know there is still a lot of time left in December, but I thought I would take a look at the early numbers. Through the 7th of December it is the warmest December on record, at Waterloo. Again, we still have a lot of December to go to change the average temperature. The chart below is the average temperature in December at Waterloo through the 7th.
High temperatures Thursday are forecast to reach the mid 50s. During this time of the month and later, reaching 55° doesn’t happen very often. Check out the chart below showing the lack of 55°+ days in December.
The outlook leading up to Christmas keeps a good chance of above normal temperatures across Iowa.
