    Starting in Abilene and a Mammoth drive East on I20 To get towards the Tornado Risk today, absolutely freezing with drizzle here in West Texas. Going to go for the 10% Tornado Risk somewhere around Paris (Tx)

    Going to be touch and go but the guys are happy to go for this one.

    You'll be getting into some pretty crappy terrain, and radar coverage isn't great up there due to the distance to the nearest radar site, which might make identifying the cells to be on difficult. It may well be a needle in a hasystack affair trying to find tornadic cells given this, but there will be plenty of storms to chase, and I'd imagine it would stay active into the evening hours given more chances for these great lightning shots you have been coming up with!

    If you are still only jsut setting off, my only worry would be if the storms fired too early for you to get on, but there is a risk of storms further SW if you need to dro back at least

    Paris TX good, though I would be inclined to drop a tad further south onto the I30 in line with Sulphur Sprs with a west to east option. The SPC just beat me to generating a risk box exactly where they have the 10% risk. Tornadoes are not guaranteed today with rather weak low level shear. Though it has to be said that the narrow risk corridor defined by the SPC will be the only field to play on today. So, all or bust!

    A small wave feature is expected to develop by mid afternoon advancing another run of convection. Worth noting exceptional moisture with low LFC. A few funnels should be in order within storm initiation, atleast.

    Paul's latest video briefing can be found here:

    I can see the video but there's no sound. B)

    It's me, something very strange is happening. I can't play any sounds through IE.

    We've tweaked a few settings again today to try and get everything we can out of the connection - they'll be in a good reception area for much of the journey east but it does get more patchy the further northeast in texas you are...

    This is a difficult situation. Severe storms will no doubt erupt in northeast TX but the further north they track, the more likely they are to be obscured by "grunge" ahead of the cold front. I have the feeling that the best viewing opportunities may come a bit further south around Corsicana, Athens and Tyler to the southeast of Dallas.

    By tonight this severe complex will become a heavy rain producer and there could be some serious flooding in eastern TX and southern AR by morning. In fact, there could be flood risks even during the storm chase especially if the team is north of the I-20 route east of Dallas.

    Yep, as Roger had said above it doesn't look pretty. Huge storm warning box just gone up south of them too.

    The teams current position puts them in line with the trailing cold front but any low mid level shear will be further east along the CF exclusive to the extreme NE TX/ AK state border within the next couple of hrs. This will now make it impossible for the guys to get there in time!

    I do not see the SPC going moderate with this risk and I do not see any increase risk of tornado development; 10% seems about right given the most recent update from the RUC model. Tornadoes are marginally possible IMO before around 01Z or 7pm CDT, though it is quite possible that no tornadoes will occur during this watch given the amount of rain cooled air being delivered over such a broad region. Another restrictive factor by early evening will be warming from the mid level downward as increase in temp at 500 mb is noted.

    PS. Paul if you get to read this; Prob not worth chasing down into Louisiana tomorrow when you have some good potential back on the southern plains by Tues!

    OK, Steve storms is set up in clear air at the moment at Fannin county. Not a million miles away from Paul & team. Maybe they'll run into each other but i think he's going to push SE to miss most of the rain that's coming with this monster.

    Hi Tony

    Yeah am happy about Tuesdays Risk, looks like a good opportunity for Tornadoes. Am seriously thinking now to head to the East and South East of the DFW Metroplex and see if something can pop down to the South of DFW And Trundle North East to the East if DFW. The LCL's today are ridiculous, Visibility about 1/4 Mile and Temp and Dewpoint spread about the Same, going to move from Decatur in a Mo and head East on Highway 380 and then Evaluate from there, much too much rain cooled air further North East and temps only 19c

    Just took an executive Decision on Today and am going to call it a day, we are too far West and not liking the look of driving for 6 hours for most probably little Reward. So we will return to Decatur for the evening.

    I remember us being laughed at for calling that place "De Catt' urr" instead of "De Kay Tah". Have a lovely night and hope you have better luck for tomorrow, everyone, it's been brilliant reading what's going on from here. Have some good steaks & beers :-
