Rain in Coralville and Iowa City

The radar shows two storms moving south through Johnson County this evening. The view from the camera is looking west from Coralville. You can see the rain from the cell NE of Coralville in the camera shot.

Here is a later image of the radar and camera. It was raining in Coralville where the camera is located. The shower is so small you can look through the rain and see the sun as it was setting. Pretty cool.

This image shows the sky is clear as the sun closes in on the horizon.

Here is a screen capture of the camera at the University of Iowa as it was raining.

Here is the tweet, of the rain, at the Iowa City newsroom.

Funnel Clouds Sunday

Cold air funnel cloud reports started coming in just before 3 PM from Dike to Waterloo. More funnel reports came in for Tiffin and Coralville between 4:30 PM and 5 PM. Cold air funnels are typically brief, drop a few hundred feet from the cloud base and don’t touch the ground to become tornadoes. Below are some of the pictures shared with KWWL.

Signs of Spring

Not only do we look for warmer weather in the spring, but there is more daylight. March and April are 2 months of the year when the daylight increases the fastest.  The chart below shows the length of daylight for each day of the year. Notice how one month from now we gain about 1.5 hours of daylight. This weekend we “spring ahead”. Change the clocks ahead one hour Sunday morning.

The Physics of Snowboarding

The Winter Olympics in PyeongChang, South Korea are underway. On Tuesday night, the world saw Shaun White win his third gold medal in the half-pipe snowboarding event.

Have you ever considered the science behind the sport?

Snowboarders have many factors at work as they travel up and down the half-pipe.

  • G-force: the force of gravity. When it comes to snowboarding, gravity pulls the athlete back into the half-pipe and he or she has to push back against gravity to fly high in the air.
  • Kinetic energy: the energy of motion. An athlete can get higher off of the half-pipe when this energy is greater.
  • Potential energy: stored energy. Potential energy decreases when the snowboarder moves along the halfpipe (as kinetic/movement energy increases). Maximum potential energy is realized when snowboarders reach their peak height off of the half-pipe.

The height of the half-pipe also comes into play. The higher the half-pipe, the more kinetic energy a snowboarder can build. The Olympic half-pipe is at least 20 feet high.

For more information, watch this video from previous winter Olympics from NBC Learn.

Volcanic Eruption

One of the most active volcanoes in the Philippines erupted earlier this week.

Mount Mayon in the Philippines began spewing ash and lava after being on alert since last week. Due to the eruption this week, the alert level increased to a level four (out of a scale of five) and the area of concern expanded. Over 50,000 people moved to shelter camps due to the volcano.

Officials are urging residents to stay out of the danger zone as a more violent eruption is possible. Lava flows littered with debris pose a fatal danger to life and property.

The Philippines is located in the “Ring of Fire”, where most earthquake and volcanic activity occurs.

Finally Above Freezing

We’ll call it our second “January thaw.”  Temperatures are finally above freezing, after a little more than 170 hours below 32° — that’s just a little more than 7 days.  On January 11th, a very strong cold front plowed through eastern Iowa early in the morning, taking temperatures in the 40s at midnight, to the teens and single digits by the evening hours.

The graphs below are plotting the temperatures roughly every hour from January 11th through the 18th.  Temperatures are forecast to remain above freezing, for highs, through the weekend and even early on Monday.  Temperatures are forecast to fall below freezing later Monday morning (but not as dramatic of a drop as January 11th).
