I'm jsut NE of Arkadelphia in Caddo Valley. Awaiting initiation down here...

[multi cellular thunderstorm]

Looks like some good cells developing on the Oklahoma/Arkansas border.

Stu Robinson is around the area now.

Situation looks volatile now, I think we should see explosive development in about an hour or two. The dry line turning into P front is still west of FTW and passing Ardmore (26 dp there), runs into e OK, then P warm front extends ESE through s/c AR. M cold front is about Clinton to Childress and also ready to activate.

I think we'll see some supercell development in ne TX perhaps in the DFW metroplex or slightly east to south of there along the P front, then this should phase with rapid development in e OK and w AR to provide some tornadic cells, the question is whether they might reach given locations before sunset around 02z. I would think Texarkana to Hope AR might be a good location at present, 00-01z for arrival of storms there.

SURFACE-BASED STORM DEVELOPMENT. STORMS/SUPERCELLS DEVELOPING IN

UNPERTURBED AIR MASS ACROSS ERN/SERN OK WILL ENCOUNTER MOIST LOW

LEVEL ELY/SELY FLOW NEAR THE WARM FRONT/OUTFLOW BOUNDARY ACROSS AR

SHORTLY. LOW LEVEL SHEAR ALONG THIS BOUNDARY...AND ACROSS THE REST

OF THE WARM SECTOR...WILL SUPPORT LONG-LIVED UPDRAFT ROTATION. A

CORRIDOR OF GREATER POTENTIAL FOR STRONG TO INTENSE LOW LEVEL STORMS

Great to see the legendary Michael fish in here!!

Michael, it's a real shame I never had the chance to meet you and go chasing on Tour 1 with yourself. (I'm on tour 3 now). Sounds like you had a fantastic time and I followed your every move. Your blogs were indepth and very interesting, especially so as I will be experiencing the same environment and weather conditions.

I just wanted you to know I've met Ivor Moores and Peter Gibbs and........ my uncle works at the Met-Office

Kind regards Michael

[Karen Ann]

Lovely. I'll catch up with the piccies and updates in the morning then. Hey guys, you take care out there, I've been keeping a quiet eye on you from the start and now I'm fretting like a mother hen ..... thank god I don't actually know you, know you (if you know what I mean)... I'd be an absolute wreck.

[kold weather]

Some explosive convection occuring in the main risk zone, some really powerful cells developing, several likely to be supercells already and I bet some are already in the severe category as well producing big ole hail. Certainly some good convection occuring what appears to be the dryline...this looks like its going to be a really good day for storm chasers, fairly spread out cells esp further south in the mod zone, got a good feeling we will be seeing tube photos soon...

[Tom Lynch]

NOAA Weather radio warning of a Dangerous Day ahead today, so take care teams, We certainly will NOT Be core punching today with the risk of Strong and Damaging Tornadoes likely. Temp here is unbearable with 80c and a Dewpoint of 73c

Good luck today Steve, today has all the hallmarks of going HIGH Risk and picking a chase target is an absolute mare when the Moderate risk covers thousands of square miles Still looking over Models and still scratching my head!

I am now counting down to Wednesday. I arrive in Oklhoma City at 5.00pm Wednesday. What is the feeling on how this week will pan out. I see storms are supposed to be on the cards for Tuesday/Wednesday.
