Models have a cooler start to June with -NAO trying to develop..
If the ridge over the Davis Strait ends up verifying, that would be good for my N. Atlantic SST prediction of wintertime NAO state, but still a long ways to go (the index measures through September.)
I also think a ridge is going to try to develop over the West coast through June, then it may work its way to the Midwest by July and August then the east by the end of the Summer.. there is a chance it could come here sooner though, but GEFS looks troughy through Day 15..
June's looking like a write-off
