Today boasts a dryline setup in Central OK down to NW Texas, but I'm not too excited about it. As usual, cap strength is hard to get a handle on, and the haze and smoke still presents visibility problems. Meanwhile, the dryline has been a little unpredictable this morning - it should have drifted west some through midday as winds backed ahead of the developing surface low in SE Colorado, but it seems to have made some eastward progress (roughly 100 miles) over the past couple of hours in NW TX. Why? Hell if I know. Perhaps it has something to do with ongoing elevated convection in that same general area. Or perhaps the surface low isn't deepening as rapidly as expected. Areas west of I-44 also look to be on the wrong side of the moisture axis right now...low level moisture is pretty good, but there's a lot of dry air once you hit 850 mb.
