Holly CO media coverage

There is quite a bit of coverage of the Holly aftermath in The Rocky Mountain News.

http://www.rockymountainnews.com/

Anyone want to venture a guess at the EF-rating from the picture there? It seems the houses on the left side of the picture were not (directly) struck by the tornado, but judging from the defoliation and debris lying on the ground (hard to say exactly from the pic, but there had apparently been a house in the foreground), it won't surprise me to see an EF-4 rating forthcoming.

Note how, as opposed to residents of OK/TX, for example, people in Denver are unfamiliar with the dryline. The article calls it the "dry line" (including quotation marks). I can picture plenty of people there thinking "the what?", LOL.

*edit Okay, I just looked at the slide show, and I don't believe I see anything there that looks like >EF-3 damage.

My preliminary analysis based on the RockyMountainNews slideshow would be a EF3 at that particular area. The actual NWS survey will take a look at the tornado from start to finish to determine its intensity at different locations, but in the location the news slideshow focused on I would say very strong EF2, but a more probable EF3.

In case anyone hadn't noticed, NWS Amarillo has posted a website dedicated to the event. There is mention of "several" tornadoes producing damage in the EF-3 range. It does not appear that any of the damage surveys are complete as of today.

I know the weather service in AMA is still trying to decide if a tornado even hit McLean, but those those of you who were their like me, you know that a tornado definitely went across the far east side of town. KVII in Ama fowarded my images on to them to help them sort out what happened. I am figuring alot of the Panhandle tornadoes might get underrated due to the fact they kept from hitting too many structures from what I saw luckily. I guess we will wait and see.

NWS Pueblo has rated the Holly tornado low EF-3 in the town, but high EF-3 12 miles north of town.

Think what it would be like to try to explain the Denver Convergence Zone.

As for the dryline, the dewpoint at my house, on the southern edge of the Denver metro area, was 41F at midnight, dropped to -7 during the day was -1 at the time of the tornado at 8PM.

Not sure if anyone posted this yet. Preliminary storm survey results for march 28, 2007:

Anyone know the tornado count for the March 28 outbreak. From what I can tell, it's around 30.

[Brian Stertz]

Just wondering where the NWS LBB has placed the damage ratings for the tornadoes. Not that there was a whole lot to hit in that part of the Caprock, but certainly a couple had the potential F2 appearance.

 

[David Drummond]

None that I have seen Brian. They haven't sent out the media briefing on it yet either.

 

[Jeff Snyder]

Yeah, I wonder what seems to be the hangup in terms of rating the tornadoes (or releasing the ratings). Since the EF scale includes DIs for trees and other such things, I'm sure they'd diligently rate it even if no "structure" was hit. The LUB website has a page on the 3-28 tornadoes, but just links to a summary list of LSRs without mention of rating(s).

FWIW, many of the EF2-EF3 tornadoes that occurred in the TX panhandle didn't hit much in way of substantial buildings, so it seem that new DIs associated with the EF-scale helped substantiate these ratings (or else we may have only seen more F0-F1 ratings given that there wasn't much destruction to "well-built single-family houses").

AMA NWS site has a number of pages assembled now on the March 28th outbreak: http://www.srh.noaa.gov/ama/march2007_tornado_outbreak/index.htm

Man, that's a lot of stuff to go over - impressive. I'll ponder all this for awhile.

I don't quite understand the corrected position for the Jericho tornado. I don't see where it mentions the original position first. It isn't referring to the one previous 6 to 7 miles sw of Mclean is it, because I believe that is fairly correct and likely the one I took a picture of.
