Chase 2009 - Day 1 - Central/nw Texas

[sammie]

thanks Ross. even though we dont have such severe weather, perhaps we could take a leaf out of the US media's book and have better "current conditions" reports here

To be honest they need it we really don't as much. It is literally a matter of life or death there. Would be nice, but not needed in reality and that will always win.

yep agree there

Been out most of the weekend and come back to find my sis has buggered the computer. Gonna be following this on the laptop for the rest of the evening. Not surprised at the High risk, but quite surprised to see the eastern extent of the 5% tornado range. Team could be watching out for overnight tornadoes in the early hours once they get back to their Hotel.

[Nick F]

Strongest 0-1km SR Heliciy values and 0-1km shear vectors atm across Wern OK around Arnett looking at the hourly mesoscale, but favourable further south into NW/N-central Texas too:

Insane SBCAPE across NW TX:

Dryline has past east of Amarillo looking at sfc obs:

It will be an interesting decision which way to go when the team touch down. Just so I can work out driving times and possible realistic ranges does anyone know how long it takes to drive from DFW to Oklahoma City? Thanks.

Takes about 2 1/2 to 3 hrs to Oklahoma City from DFW. I suspect Paul is intending to head up Hwy 287 towards Witchita Falls when they leave the hotel, that was what him and I discussed last night, and I think this still seems the best option later as storms continue to grow and develop in that tornado watch area just NW of Witchita Falls.

Thanks Nick. Certainly looks like the direction to be going in with a storm already showing up north of Aspermont.

They have landed if they were on the American Airlines flight. I didn't realise you can track them with a live map in the air as well!

BA flight is scheduled to be 30minutes late - currently above Teneesseeeeeeeeeeeeeeeeeee

latest forecast update from conv discussion

...CURRENT THINKING ACROSS THE MODERATE AND HIGH RISK AREAS...

THE LARGE MCS FROM NW OK EXTENDING NNEWD ACROSS KS INTO NEB AND IA

IS ORGANIZING INTO A LINEAR MCS AND WILL CONTINUE TO HAVE A

WIDESPREAD SEVERE THREAT LATE THIS AFTERNOON INTO THE MID-EVENING.

RUC ANALYZED INSTABILITY AND VERTICAL SHEAR FIELDS APPEAR FAVORABLE

FOR AN EXTENSIVE SEVERE THREAT COVERAGE. LARGE HAIL AND WIND DAMAGE

SHOULD ACCOMPANY THE STRONGER CELLS IN THE SQUALL-LINE EWD ACROSS

THE REMAINDER OF KS INTO NW MO AND SRN IA. A FEW TORNADOES SHOULD

OCCUR WITH SUPERCELLS EMBEDDED IN THE LINE OR AHEAD OF THE LINE

THROUGH EARLY TO MID-EVENING.

[Roger J Smith]

Here's the current radar for areas west of DFW showing a few developing severe storms. Everything else further north in OK and KS would be too far away for jet-weary storm chasers, but this stuff is about two hours away from DFW and moving quite slowly to the northeast.

http://radar.weather.gov/radar.php?rid=fdr...111&loop=no

Check the time code (UTC = z) for an updated view.

I think this activity west of SPS (Wichita Falls TX) might generate a weak tornado later today, although it is not exactly rambunctious, certainly a heavy rain and hail producer. The outlook is for it to continue through much of tonight as upper dynamics actually intensify somewhat balancing the lower diurnal index.

The general pattern should repeat a little further southeast tomorrow.

If anyone wants to have a look at the GRLevel3 that the team are using then there is a 21 day trial available..

Yeah but they've took away at the smoothing ability, ! That was free on the one i downloaded on another laptop for the 2007 chase.

thanks roger and paul

Tim Purington cam has been quite interesting: http://severestudios.com/livechase

Interesting how? The internet here is no where near fast enough to stream anything.

There was a bit of a lowering which he was zooming in on but it pretty much dissappeared just as i posted it :lol:

That website streams a lot better than TVN.

True.. but it gives people an idea how it works. I might have to shell out for the full version..

Would anyone mind me doing penny for the guy a bit early? :lol:

Damn lol! I can't stream anything, the internet keals over between the hours of 6pm and 2am here when everyone is on it. I'm struggling to load the forums at the moment alone.

[Nick F]

Still a long old haul to the west of Witchita Falls where the nearest storms are, could looking at a 2 to 2 1/2 drive there giving some welly to get on it, still no signs yet of storms erupting further east - though GFS and WRF do break it out towards DFW by midnight here.

Some good breaks with Cu fields SW and S of Witchita F now;

[Ross B]

Rotation and possible funnel on Andy Gabrielson cam now!!!!!!!!!

edit: think funnel is out of view now...

cam now offline , to many people viewing!

Definite Funnel/Tornado on that cam now!!!

[tom_f123]

[MAF]

[Ross B]

Neither can we really, only saw a quick glimpse of the funnel before the stream went town.
