Probably due to more stable air there at the moment, but a watch is possible there later.
Also not having a watch is no guarantee that nothing will happen - the Atlanta tornado took place with no watch box anywhere near there...
Not to mention it was the second time that tornado warnings were issued with no watch in place in the Atlanta Metro area (Cobb County the week before and Fulton County last weekend) in as many weeks.
We've been to the basement for four warnings in the last two weeks. This is not normal spring patterns in this area.

Re: Next big severe outbreak starts Monday?
Just in case, I have my girls looking for flashlights and the little one is asking if there is going to be a "tomato" tonight. Looks like a night for the NOAA Weather radio.

Re: Next big severe outbreak starts Monday?
The two tornadic cells nearest Abilene were one cell that split, with both the more left moving one and the right moving one becoming potentially tornadic.
I don't know all the factos that go into splitting supercells, but I thought usually the leftward moving one usually weakened.

Re: Next big severe outbreak starts Monday?
Impressive forecast soundings for HOU area between 7 am and 1 pm.
Can't get a forecast skew-T for 10 am from the NIU site, but CAPE and deep shear (from Utah U met dept. site) look favorable for SE Texas
But 1 pm still looks pretty favorable for severe storms

Not really, both skew-T soundings suggest little instability in the lowest few hundred meters, but once to that point, nothing should stop parcels from rising.
Neither forecast skew-T has super instability, period, but both, especially the 7 am sounding, have so much low level shear. And there should be enough instability for thunderstorms that are surface or almost surface based.

Well, there is the tropopause, but that exists so we can have over-shooting tops.
