It's hard to know where to begin after watching more tornadic events unfold near Oklahoma City again last weekend.

Another 13 killed Friday's outbreak, including 3 dedicated and experienced storm researchers. A Weather Channel chase crew and car tossed around like a toy, 3 more storm chasers nearly killed as they dodge flying debris in a scene straight out of 

 as they are caught in the the tornado's path.

It's one thing to be in the path of a tornado seeking shelter in your home. It's quite another to go and seek the tornadoes out, and potentially put yourself and others in harm's way.

How do we best keep researchers safe as they try to collect valuable data on tornadoes that may help save future lives? How do we keep the public safe as they are caught in "tornado traffic jams" that are partially created by the swarm of tornado chasers and researchers?

It's as if somebody painted a big tornado target centered on Oklahoma City this year.

Friday's outbreak extended into Missouri and Illinois, but the most dramatic events occurred again just west of Oklahoma City, where another 13 people were killed.

Among them was a dedicated lifelong storm researcher...Tim Samaras, his son Paul and Carl Young, caught in the tornado's path as it made a sudden shift to the right.

Our hearts go out to the Samaras and Young families, and everyone else killed, injured and suddenly homeless in the incredible May "tornado swarm" in Oklahoma.

I'm not even sure where to begin on processing this tragic event, and I don't pretend to have all the answers. But here are some thoughts on the tragic events in Oklahoma Friday evening.

As tragic as events have been in Oklahoma in May, you have to give NOAA/NWS a lot of credit for advance outlooks, warnings and saving hundreds of lives.

As with the devastating Moore, OK tornado on May 20th, Friday's twisters had plenty of notice....from SPC outlooks of a "moderate risk" area days in advance...to the issuance of a rare "Particularly Dangerous Situation" (PDS) Tornado Watch well in advance of Friday's storms.

As with the 16-30 minutes lead time on the devastating EF-5 Moore tornado on May 20th, Friday was another "meteorological success story."  NOAA/NWS saw this coming...and saved many lives.

Here's the radar loop from the Norman, OK NWS showing the storms blowing up, and turning tornadic as tornado warning boxes are issued in advance of the storms.

Here's a closer look at the El Reno tornado showing the "reflectivity hook" on doppler...the tornado's signature.

The El Rio tornado that killed Tim Samaras and tossed around a Weather Channel crew including Mike Bettes is rated an EF-3 twister by the Norman, Oklahoma NWS.

The twister near El Reno took an erratic path, and took a sharp right turn right along I-40 near the end of it's path. That may have been what caught so many off guard who were following the storm...and put them directly in harm's way.

An EF-3 tornado running right over a major interstate highway is one of our worst nightmares as meteorologists. There were few good options for getting out of the way, especially as traffic stacked up.

What do you do when caught in a car during rush hour as a tornado approaches? There is some evidence that you may be safer in weak EF-0 or EF-1 tornadoes in your car than lying in a ditch. But the El Reno was an EF-3 monster...capable of tossing around trucks like toys.

Tim and his crew had decades of experience researching tornadic storms. They were not "tornado tourists" or thirll seekers.

look at Tim's life passion for researching storms

Tim was well know in the Minnesota storm research community. Here's more about Tim from a letter sent to me by John Wetter a local SKYWARN storm spotter and Coordinator of the Minnesota Skywarn Workshop.

John has more on Tim and storm chasing with Cathy Wurzer on Morning Edition today.

The Samaras crew was not the only one caught in the Twister. Oklahoma University meteorology student Brandon Sullivan and fellow storm chaser Brett Wright were 

 and posted their video on You Tube. These three clearly know they are in trouble, and it is amazing they survived the flying debris, and a collision with the SUV that races around them on the left.

It's a scene straight out of Twister with one exception. It's alarmingly real.

Weather Channel Crew tossed around and injured:

Even The Weather Channel is not immune to becoming a tornado target. Mike Bettes and his crew were thrown 200 yards by the twister, and survived.

The deaths Friday evening do raise some serious questions about a possible safety protocol for storm research vehicles.

I don't have all the answers...but I do think there are some important questions that need to be answered to keep the researchers and the public they are trying to protect... safer.

-Does it make sense to separate out storm researchers, trained weather spotters (SKYWARN) and journalists from "chasers" (thrill seekers), and "tornado tourists" and "profit seekers" out to make a quick buck on the latest tornado video for CNN?

-Would some type of "permitting system" make sense to ease crowding on roads and major highways as tornadoes approach? (Yes, there are literally tornado chase "traffic jams" at times in Tornado Alley. Perhaps an odd-even day system...or a one week permit for those who are not "accredited" researchers/spotters?

-If a "permitting" system were adopted, what level of training would be required to "chase" tornadic storms? What would be the "rules of the road?" What would be the consequences for "unauthorized chasing?"

-Can we come up with better options for communicating effective options for seeking shelter for those caught in cars as a tornado approaches?

Food for thought as we travel further into the active tornado season of 2013.
