24 hour rainfall totals

Overnight rainfall amounts a bit higher than expected due to strong low level jet and high dew points. Last night’s rain shouldn’t raise flood waters any substantial amount, but instead will slow their fall back to normal levels a bit. Here are the latest numbers from observers around the area:

                                               RAIN

Upper atmospheric research!

I was able to fly with Rob Holland in his Window World MX2 airplane today. We were able to get video of my experience as I handled 5G’s through some parts of the flight. During these extreme maneuvers, I felt my weight shoot up to 825 lbs. For more information, visit http://www.ultimateairshows.com/

Some stats about Rob’s MX2..

Weight: about 1,500 lbs (about half that of a small car)
Power: 385HP 6 cylinder engine
Maximum Rotation: 420 degrees per second (remember, a complete loop is 360!)
Maximum G’s: 5G (my flight)  10G’s (what he feels during the airshow) 16G’s (what this aircraft can handle)

…at 10G’s, a 180lb man would weigh an astonishing 1,800lbs…more than the  weight of the aircraft!

Happening Now: Showers moving in

As I mentioned in 13 News at 6, subtle pressure falls to the west have helped a few showers initiate and move into the Stateline. These showers will be spotty in nature and should not amount to much as far as rainfall totals go. Look for scattered rain chances to continue through the early portions of Saturday. After this area of low pressure passes, high pressure will build in from the north and provide clear skies and light winds for Rockford AirFest this weekend!

Tropical Outlook

tropical4

The National Hurricane Center is not impressed with one of the spots in the Caribbean, but the other one could be interesting to watch in the next couple of days.

The first tropical wave is over an area in the southeastern Caribbean Sea. The wave is a patch of disorganized showers and storms and is moving west around 15-20 mph. It is unlikely that this will become anything severe because the atmospheric conditions that the wave is heading into are not favorable.

The second area of showers and thunderstorms is located over the eastern Atlantic Ocean about 700 miles southwest of the Cape Verde Islands. These storms are being watched because there is another tropical wave moving off the coast of Africa that is more organized. The NHC thinks that these two systems could interact in the next couple of days. The atmospheric conditions are not that impressive but if they form into one wave, it could be worth watching.

Severe storms to remain south

121Although thunderstorms are a good possibility Friday, the likelihood of the storms becoming severe is low. A warm front will pass to the southwest of Rockford and keep our airmass a bit cooler and more stable. We tend to talk about the triple point (Cold front, Low, and Warm front) intersection as a prime location for severe weather and all of these features will pass south of us. Other than a couple of lingering showers early on Saturday, conditions will be sunny and comfortable this weekend.

Airfest-cast

120 Aside from a bit of rain early Saturday morning, this weekend looks to be spectacular for Rockford AirFest. High pressure will move in and keep skies mostly sunny and temperatures into the lower 80’s! For more information on this weekend’s attractions, visit http://www.flyrfd.com/airfest.html

“Holy Giant Hail Batman!”

hailhail2Imagine a ball of ice falling from the sky that is about the size of a small cantaloupe. That happened on the evening of July 23, 2010 as severe storms rolled through northeastern South Dakota. In the town of Vivian, a severe storm unleashed hailstones that were large enough to create holes the size of coffee cans in the ground.
A ranch hand at a local farm watched in awe as the storm moved through. After the it passed, he went out to look at the damage and that is when the hailstone caught his eye. The chunk of ice weighed almost 2 pounds, was 8 inches in diameter and 18 ½ inches in circumference.
The current record setting hailstone is 7 inches and about 18.75 in circumference, that fell on June 22, 2003 in Aurora, Nebraska. It is more than likely that the South Dakota hailstone will break the Nebraska record. However, we’ll have to wait for an official answer from NOAA’s National Climate Extremes Committee.

Unbelievable Milwaukee flood video

milwaukee_floodmilwaukee_flood1This video came into the Weather Center this evening, six days after record flash flooding affected the Milwaukee Metro area. Before you view it, be warned there is explicit language in the video which is not suitable for some viewers. Click on the map above to view the video in YouTube. In addition, these “kids” are breaking all of the rules when it comes to flood safety. Whenever there is flooding, assume there is debris, fecal matter, and chemicals in the water that can make you very sick. In addition, being in a flash flood like this can cause you to lose your footing causing injury or death.

A University of Wisconsin-Milwaukee student was killed when his car was swept off the road during the flooding.

Before you complain about the weather, watch this video

This story from CBS News took A LOT of planning. Great piece about how we’re just a bunch of complainers when it comes to the weather. -ES

p.s. This is the first blog post that warrants the tags “winter storm” AND “heat wave.” :-)
