that also points to a dangerous hurricane season imo, if all of Florida and the Gulf Coast is that much below normal that means it's much wetter and likely a lot of that is accounted for by tropical storm and hurricane activity. The subtropical jet typically lifts at some point in June so that's not a factor.
IMO that forecast is a very 2021-ish pattern. The worst of the above average heat and drought is concentrated in the west and northwest. San Antonio near average and above average rainfall/lower temps for the Southeast, less rain in the Northeast, about average temps/rain in the upper Midwest and above average US-landfalling hurricane season.
Maybe Seattle won't get to 100+ this time around, but, ya never know
