It would appear a Bermuda High like feature or something similar to trying to build into the Western Atlantic already. It will be interesting to watch this feature in the coming days and the next couple of months as we transition through Spring into Summer:
GFS Sea-level pressure 144 hours:

GFS 18Z 500MB, very summer-like ridging across the entire northern Atlantic. Note Azores-High feature also.
