That’s the real problem is this pattern is funneling warm air up from the gulf, but if the ridge axis sets up where you want it to, I think we can squeeze out a mostly rain-free period. I think 90 is a reach but it’s within the range of plausible solutions from what I’ve seen on the models and ensembles. Especially the Canadian, but that might be overblown.
The other weird thing is, as much of a warm month as May was in the 2010s, we have not set a daily record high on any day in May since 1993.
