Appears there may be a confluence boundary east of the dryline in TX near Stephen county, seen when DYX was in clear air mode 45 mins ago. Just sat through some rain here in Ardmore... Winds have backed nicely north of here in Paul's Valley and Ada (with SSE-SE winds and 10F dewpoint depression, meaning locally lowered LCLs), with real cells maturing in Lincoln county and northern Oklahoma City. I'm a little concerned with storm mode... Shear vectors are out of the SW right now, which is nearly parallel to the dryline, particularly in central OK.
Substantial pressure falls are occurring in western OK and TX as strong large-scale ascent commences ahead of the vort max in NM. With the max pressure flals to the west, isollabaric forcing would indicated that our winds will begin to back east of the dryline... KTLX shows the dryline nicely moving back to the NW through OKC, not that that concerns me too much since I'm in Ardmore. Some echoes continue near Throckmorton and into Palo Pinto co. TX, but I assume those are elevated in origin. 20z OUN sounding showed no cap, though 18z DFW/FWD sounding showed substantial capping remained. The current light precip is falling through the capping layer, which should be resulting in evaporative cooling, which may actually help us remove the cap. Of course, it'll cool the surface temps as well, but continued strong southerly flow should help bring back warmer surface air.
