I'm looking at SSD IR loop of 94L and noticing that the COC is intensifying and becoming more defined, with persistent convection over the COC for the last 6 hours . Further, it appears to be spinning off the northern convective shield, as a band of warmer cloud tops has now appeared between the COC and the northern convective shield. If I had to hazard a guess, I'd say 94L is in the process of consolidating it's convective pattern into a TD/TS at present, and would not be surprised to see this become TD#4 at 11pm. Water vapor also shows this.

The SSMIS microwave overpass shows a definite strong convective band at the core, but no evidence of banding yet. Though we'd not normally expect that yet at this stage.
