Expect thin and early season. High elevation and north facing seems like your best bet as south facing stuff is getting hammered by the sun. I might be wrong but I don't think there's been much of an inversion going on. I'm gonna go take a look at Sumallo this afternoon. Rambles might be in as I heard Carl's Berg was forming up on Wednesday and Rambles are shadier. Other early formers that are worth checking out are Isodorth & Belmore (there's a new zip line access across the river to these), North Joffre, Falls Lake cirque, Zeppelin on the Darkside, Once in a Red Moon, Night N Gale, Husume Buttress, Oregon Jack, Phair Creek and stuff like that.
It might also be a good weekend to try for something a little bit more alpine like Ghost Passenger or Zero Gully. You can drive pretty high, and below 2000 m there isn't much avvy hazard. But approaching may suck as I've heard there is lots of breakable crust around.
