Tuesday looks to be an almost definite chase day, at least in my opinion... With strong deep-layer veering and at least modest flow throughout the troposphere (with GFS being stronger with the overall flow), 0-6km shear profiles will be quite favorable for organized supercells, particularly wherever the warm front exists (likely somewhere in northern TX or southern OK) where strongly backed boundary layer flow is forecasted. The current NAM shows 200-300 m2/s2 0-3km SRH across northern TX along the warm frontal boundary by the mid-afternoon, with convergence in the lower levels likely being strong enough to initiate deep convection. The NAM shows plentiful instability across the warm sector, with 4000-5000 j/kg sbCAPE being supported by the very moist and heated boundary layer by the afternoon across OK and TX (and strong CAPE also spreading into southern KS). I would like to see low-level flow a bit stronger, but the modest flow does support very slow storm motions ahead of the surface low. So, overall, extreme instability and strong deep-layered shear forecasted to develop across the warm sector on Tuesday virtually makes it look like an awesome chase day (although I hope I don't have to chase northeast TX or southeast OK LOL), at least in my opinion.
