Synoptic thoughts...
Tomorrow should be cooler on the coast where there's likely to be the nascent yet still feeble onshore wind developing... In the interior, probably still makes the low 80s. The hydrostatic heights are not really falling very much below 570 dm, which is technically a very warm atmosphere relative to our climate. What could offset this, however ...is if we get more organized convection sparked off and rumbling through late today and night. SPC is currently loaded everything well SW so ... not sure what there why - haven't read.
Anyway...if it stays dry, 80s in the interior tomorrow looking at that soundings. But if gets wet, that would process out the "non-Markovian" memory of the system and we'd end up more shallow cool below synoptic inversion ...
There really isn't a BD front being analyzed by WPC ( tho they seldom do)...but looking around at area obs/sat, there isn't one. The main b-c axis is up along the ST S-way, pretty far NW. But, with heights receding it's like the NAM is sort of instantiating a boundary - which isn't physically impossible to see a frontogenesis of sorts, if the flow aloft has height falls while speeding up.. The Euro and GFS seem to be doing the same thing....
It's why we get all that rain ( maybe...) the day after tomorrow. That nascent boundary provides an isotropic lifting interface, and because the flow to push it south is ultimately too weak to actually do so... we may start training a bit. It's an interesting set up. Very weak synoptic forcing, with high volatility/PWAT access... The latter is pseudo-adiabatically very unstable. It can over perform with less motivation to do so. But ... it doesn't set well with me that the NAM, which is a sneaky great tool for 'convective initiation' that few know about or use ... (sorry to see this aspect be lost by the majority that don't), has paltry totals through Monday night. Maybe 12z comes around a bit...
