multi cellular thunderstorm

Good luck hopefully Colorado delivers again today. Can't believe how quick the days pass by, day 6 already! Have a great day everyone there

The WeatherHolidays facebook page (part of Netweather) had the live stream although at times I was the only one watching! I believe it was also on the normal Netweather page though, it was patchy early on but improved after midnight.

Some really good footage on the stream tonight lovely looking structure and nice lightning looking forward to seeing some photos and videos.

Lovely temperature drop here, hit a high of 20.3C at 15:25 and now at 17:00 it's 16.5C with light rain and an amazing petrichor smell so much fresher and more comfortable, love it!

Good luck Tour 1. Looking forward to seeing the pictures and videos and catching some of the live streaming too.

Hi Tom Don't think I've been on a tour with you since 2010 so it'll be good to see you and the now famous Chicken George again! Looking forward to seeing more of Denver and Colorado too, I think I've only been there on one out of my 4 tours and loved it. 6 weeks today until most of us on Tour 4 will be arriving/meeting up in Denver. Feels like it's taken months just to get from 8 weeks to 6 weeks but getting there slowly.

It really does become an addiction, I wasn't supposed to be going this year but I couldn't resist! Sounds great I've never been to Denver, just passed by on a previous tour. I've landed in Dallas all the other times I've been.

Hi This will be my 5th time and I'm just as excited as I was the first time, if not more! It seems most of us are on the later BA flight on the 23rd. Are you arriving on the 11th or 12th? I'm sure you'll have an amazing time, even taking away the storms it's such a great experience travelling around the states with a lovely bunch of crazy people, eating amazing food and having a few drinks too. Fingers crossed for plenty of supercells and some tornados but even on down days there's always something interesting and memorable to do and sometimes the odd slower paced relaxing day can be nice to recharge, but hopefully there aren't too many of them PS. Just sent a friend request on facebook in case you're wondering who it is, I'm Mark.

Regarding the tripod, I'd strongly advise against getting a cheap one there! I got one last time and it was the most useless tripod I've ever had and prevented me taking long exposures of lightning if there was the slightest breeze. Had to tape it up within a few days too as it was broken pretty much out of the box. There may be some better ones available somewhere like Best Buy but I'm planning on getting a decent (£40-50) travel tripod before I go this time.

Can't wait! Already got you on facebook but anyone else going feel free to add me. Here's a link https://www.facebook.com/mark.pritchard.965 or if you search Mark Pritchard I have an awful selfie where I'm dressed for a wedding. Hoping to replace it with one with a tornado in the background fingers crossed!

No I think I'll be going from Edinburgh via Chicago. It's cheaper and easier.

Looks like I'm definitely joining Tour 4 I'm looking to arrive a day early too and stay at Days Inn on Tower Road.

It looks like your flights would be much cheaper if you arrived on the 12th. I'm seeing £541 return from Gatwick with Norwegian, but that doesn't seem to be available for the 11th :/

Hi I've been four times and only once arrived a day early, but it was well worth it, I'd definitely recommend that if you don't mind the cost of the extra night. I might yet be joining Tour 4, I need to sell some stuff and work some overtime but I'm hoping to take a space if I can. The draw of storm chasing is just too strong!

Lovely looking storm this afternoon!

Already over 2000 strikes in that area that only developed within the last hour! http://en.blitzortung.org/live_dynamic_maps.php Very impressive and looking promising for the rest of N England might get out in the car and do some chasing later.

Brilliant day today, loved it, we had a bit of everything. Couldn't narrow it down to just a few photos so here's 16!

Battery is almost dead so I'm not going to say much about these but great days!

Very enjoyable, if at times a slightly scary chase day! First photo is a tornado a few miles to our west, second is a wedge to our north. Also treated to a lovely lightning display all evening and night.

Chase day 1... ...D6/Wednesday -- Southern Plains... With the approaching low and increasing southwesterly flow aloft, environmental conditions are forecast to become favorable for an uptick in severe risk over the region. Several days of south/southeasterly low-level flow will advect increasing moisture towards portions of western Texas and Oklahoma. In turn, as forcing for ascent spreads across the region in association with the approaching low, isolated to scattered thunderstorms are expected to develop. A veering wind profile with height (and sufficient southwesterly mid-level flow) would likely be supportive of updraft organization/rotation within this pattern. Deterministic/ensemble guidance are in relatively good agreement regarding the time frame for this potential, such that a 15-percent area is introduced. http://www.spc.noaa.gov/products/exper/day4-8/ Looks like a decent start

Well I haven't started packing yet so I'd also like to see what others are taking, I normally forget something. What sort of size suitcases are people taking? I'm collecting an 80 litre wheeled holdall tomorrow just hoping it's big enough. Buying my tripod out there to save on space so someone on tour 2 can have that

I'm arriving on Monday afternoon and staying at the Best Western west airport freeway. Can't believe how close it is now!

Hi Christina, I've managed with a travel tripod in the past which just fits in my camera bag. It's broken now so I'm unsure whether to keep space for a normal one or get a new small one, but I'd say definitely take one, it's pretty essential for night time lightning unless you want to balance your camera on walls or railings or the top of the car! I think the meal Paul mentioned on the night before is the 8th. The tour officially starts on the 9th but some of us are getting there early.

I'm arriving on the 8th too, haven't decided on the hotel yet but I'll get that booked soon. What time have people booked the flight home? I can't remember what I normally go for, is 15:45 too early? There's a 19:05 option but I don't know if that's a bit late. Been putting off booking my flights for ages since I missed the best prices, but I just have to bite the bullet now. Getting excited now! Looking forward to meeting some old faces and plenty of new ones too, and I'll be around on the evening of the 8th if we're having a get together EDIT: Flights booked Exciting times!

So pleased you mentioned that about Newcastle. I hadn't even considered Newcastle and was looking at going from Manchester via Chicago. Just got to decide whether to fly out a day early or not now for tour 1.
