Rockford: Lucked Out on 11/22

The "theoretical path" and actual path of the Caledonia tornado.

     This is an image of what could have theoretically been the path of the November 22 tornado, had it touched down earlier. It possibly could have sliced right through the heart of Rockford. I am working on putting together a more detailed article, with radar and explanations of what happened during the event.

Spring Fever

My first out of town chase, and my first lightning shot.

    I want to feel the way the air feels before big severe weather outbreaks. Warm, humid spring and summer days. Where that eerie stillness lingers into the afternoon. The kind of feeling old folks call "tornado weather".

    I remember when I was younger setting up my little weather station in the back yard in anticipation of thunderstorms. Then I'd go inside to my forecasting center (The Weather Channel) and begin drawing out my maps. Storms would begin to fire, and I would track them on a piece of construction paper, hoping they would come our way. I would hang my "analysis" and printed radar loops on a bulletin board, so I could track the storms movement.Come late afternoon, warnings would be issued, and I'd be outside with my dad, filming the approaching storm from the garage with my dad's giant VHS camcorder, and my Field Guide to North American Weather in hand. Although most of the storms weren't anything that special, a few do stick out in my memory.

    That may be the reason I'm a storm chaser. Something about it takes me back to the glory days of my youth. I may be a little taller now, but I'm still the same little kid inside. My appreciation for the weather hasn't changed.

    In a few months, gulf moisture will raid the southern plains, and once again, the kid inside of me can come out to play.

Storms of 2010

This is a few of our favorite pictures from our chase season. Enjoy.

The Weather of the Future... 2011 and Beyond

    2010 may have been one of the more interesting years to date regarding our planet's weather. From violent tornado outbreaks in Minnesota, record-breaking hailstones in South Dakota, to extreme flooding in the middle east, record-breaking heat waves in the United States, super-typhoons in the Pacific, and a record-breaking New Year's eve tornado outbreak, what can we expect for 2011 and years to come?

Record-breaking hailstone that fell in Vivan, South Dakota on July 23rd weighed in at 1.94 lbs, measured 8 inches in diameter and 18.5 inches in circumference.

    This year seems to be following a similar path as last year. Many signs are pointing to the possibility of a rather intense pattern over the northern and central plains, which could lead to several bouts of extreme weather producers wreaking havoc on many of the same areas hit hard during 2010.

    According to some research and statistical pattern observation, 2011 shows some parallels with the patterns leading up to 1999, one of the most infamous years of severe weather in history. If these predictions come true, it would not be unheard of for a May 3, 1999 like event to occur.

Remains of a pickup truck wrapped around a telephone pole after the devastating May 3rd, 1999 F5 tornado that struck Moore, Oklahoma. Dr. Josh Wurman, then scientist at NSSL in Norman, Oklahoma measured wind speeds up to 318 m.p.h. with his Doppler on Wheels as the tornado moved in to Moore.

     Whether there is any similarity in the patterns leading up to active years such as 1999, only time will tell what mother nature has in store for 2011. In this last decade of wild weather, it is becoming more and more important to pay attention to the sky than ever. As our planet changes, we must also change to adapt to what the skies throw at us.

My Weekend: Texas Supercells 10-22-10 + SPC High Risk 10-26-10

Starting just before 3:00, we were extremely close to a rain-wrapped tornado near Cridersville, Ohio.  The debris you see flying towards the car is pieces of paper from insulation.
