Texas Spring-2014

On radar earlier you could clearly see the dryline and cold front intersecting in that area, with storms blowing up right where they met. The triple point.

Typically with a triple point you deal with a warm front ahead of it. There wasn't one, with the cold front triple point it's a squall line. These storms fired and traveled over the same areas without a warm front from the dry-line.

Larry Mowery on channel 11 called it a "triple point". Maybe he needs the weather lesson?

David Finfrock's sidekick also called it a triple point.

It's called Gibson Ridge radar or GR radar. Here's a base velocity image from that cell. Strong rotation there.

Not the one I was thinking of, but it got the job done. Thanks for sharing. Is GR radar free or pay?

Man Denton could get hit with more hail with another severe storm heading that way. What a day they've had today. Around 4 different severe cells moved over that area I think?

Early this morning there was a segment of thunderstorms that moved a row of counties north of Denton county. I wonder if those storms from Cooke and Grayson counties left an outflow to focus all these storms in the northern tier counties of the metroplex?

Ntxw, after this event passes and you find the time, could you or another seasoned amateur or promet take the time to break down what exactly an outflow boundary is and how they influence later storms. Or if you got a good link that does as much, that'd be awesome if you shared it. Thanks!

It is a triple point, but it isn't a triple that feeds storms that keeps going over the same areas. A cold front tends to elevate the storms as they travel along it with cooler air rushing in and turning them into a squall line. The big supercells that we saw intensify and kept going usually feeds on a warm front. But there wasn't a warm front, they fed on a boundary. My bet is those storms this morning left the boundary a county to their south while they were moving west to east over Cooke and Grayson counties and east.

Pete Delkus says a possible tornado on the ground in Commerce.

It costs money. Here is a link with more details: http://grlevelx.com/

An unbelievable night unfolding here in North Texas.

And a tornado on the ground in the St. Louis metro area and tornadic storms exploding in Arkansas.

Yeah I think it might have been at the intersection between that outflow boundary to the north of DFW and the dry line approaching from the west of DFW. Both of those boundaries seemed to have stalled in that area.

A silver lining is a lot of this is training over the Lake Lavon watershed with radar estimates showing 2+ inches of rain over a large area.

Flash flooding a threat now in some parts of North Texas. Could help bump some lake levels up but it may come at a cost.

Looks like the last line of storms will be moving through lake grapevine soon, hopefully it moves slower so it can drop more rain.

[Texas Snowman]

Either Lake Ray Roberts, Lake Lewisville or both should see some inflow from the Denton County storms earlier.

The tornado watch in NE Texas, SE Oklahoma, and SW Arkansas has been extended until 4:00 am.

Whoops! That is the one I was thinking of! Thanks for sharing!

Dangerous couplet moving close to Sulphur Bluff (NE of Sulphur Springs). Tornado warning there.

Texarkana needs to keep an eye out for the one that's been making headlines. It's intact and just looks downright scary. Velocity is off the charts, amazing.

And we're looking at it from a long distance away from the radar sight.

Is there anymore info on the damage near Greenville.

Yep, Channel 3 just reported that are 100mph straight line winds reported with this storm, moving to the east at 60mph.
