Lets see some Nexrad!

One of my all-time favorites, from May 29 2004. Created in Weatherscope.

No it doesn't have a pretty hook, but that is one HUGE storm. It is in central NE, July 12, 2004 and radar indicated tops were 65,000 to 70,000 feet for about an hour. Oh and about this same time it has a wedge on the ground as well as a smaller tornado to the west of the wedge. Nothing beats a slow moving beast like that during the summer.
2132 Z - Jackson County, IL 9/22/06


Velocity: Three sups, three couplets

I probably have more than 100 radar captures on my computer from various outbreaks, supercells, and 'interesting' days (at least in terms of radar imagery)... That said, this is one of my faves:


EDIT: I found a few images that I think are cooler than the above image, but for different reasons... Here's a set of images from TLX (Oklahoma City) that shows evidence of superrefraction "bending" the radar beam down to the surface... This isn't uncommon by itself, but it picks up traffic on I40 west of OKC and I44 southwest of OKC. This shows up best on spectrum width (which isn't surprising, since the beam volume is likely filled with cars going different directions and speeds), followed by base velocity and base reflectivity:
TLX spectrum width
TLX base velocity
TLX base reflectivity
TLX base velocity (different time)
TLX base reflectivity (different time)

September 16, 2006: Minutes before Colton Tornado

April 2nd, 2005: From Marmaduke to Carthursville
Nice hook SW of Big Spring, TX on May 4th 2006. Pic is NW of Big Spring about 20 minutes before the radar image was taken.

My favourite of all time... ever! I remember watching this on the PC while listening to skywarn and scanner feeds from the net with the satellite locked onto one of the local KY news channels.


This one happened last year and is the best I've seen this summer. It was around for at least six hours, producing tornadoes and everything else. Note the hook echo on the northern end.

My choice would have to be the two supercells that formed in North Eastern Illinois on April 14th 2006 and moved South East making direct hits to the downtowns of my home town: Attica, IN, then Crawfordsville, IN followed by downtown Indianapolis. Because of the prolific hail from the southern storm (HP) many car dealerships were completely destroyed (hail to 2.5 in.). In the end the storms caused an estimated $1 Billion dollars and put Indiana at number one for storm claims in 2006.

I chased this storm from Attica to just north of Crawfordsville and it was the best structure I have ever seen!

Well, as we do not a high resolution radar system in Brazil and we do not even dream tro have a Nexrad, i think you would be interested in a weather radar picture depicting a tropical system off the coast of Rio Grande do Sul in February 2006:

Another example of traffic... (AMA is well known for this)

A nice squall line...

Stereotypical 3-D structure of a large, cyclic supercell (what you see more often than not based off my experience; supercells' 3-D Z structure can actually vary quite substantially)

Just a nice typhoon...

Too many to post! Props to Tom for displaying the 5/1-5/2/2002 supercells. The southern storm goes down as one of the most impressive I've personally witnessed on radar. It tracked from St. Louis to N.C.

Thanks for posting the pictures! Those are some very impressive storms. I'm trying to dig up some that I took last year, but I'm having problems finding my flash drive....doh.

I was curious if anyone has some Nexrad captures with returns in 75+ dbz range? Lets see those big hailers!
A nice squall line...

Nice? What you have there is monstrous in terms of scale. I like the traffic grabs you and Jeff submitted. Radar anomalies can be very enlightening. Here are my submissions:

Sure are some great screenshots here. Really like the 3-D images, which software package produces them?

While not as spectacular due to our EC radar page, the storm that produced the images did some spectacular damage, and almost landed a 200+ year-old tree in my living room. In the pic, my house is on the left.

Here is a storm that hit Amarillo, TX on June 21, 2004. It had 4+ inch hail (that i was able to stay out of) and 4 or so confirmed tornadoes (all F0 or F1).

Here are a couple pictures of what the hail did across western Amarillo. I drove around that side of town the next day and there were trees branches down everywhere and just about every car was missing a window. Definitely the worst hail damage I have ever seen.



Also here is a link to the radar loop for the afternoon.

From August 24, 2006 in South Dakota:

Reflectivity at the time of the Roanoke, IL F4 (it was hitting the Parson's plant at this time; hence the area of high reflectivity at the tip of the hook from debris):

Storm Relative Velocity of the Roanoke, IL tornado:
The first few grabs were from a storm that I caught moving across the northern side of the Houston area. It produced close to baseball sized hail and the best structure I have seen here along the gulf coast. It had bright white hail streaks coming out of the back of it and at the same time my friend was caught in golf ball sized hail that severely damaged his car. As you can see from the radar, this storm topped out above 50kft!

The next few are from the March 2000 Fort Worth tornado.

This was about as close of a "backyard" chase as I ever want to have, lol. It hit the apartment complexe i am living in now, and missed the guy's hose who was chasing with me by about 1/2 a mile at the most.
