That’s not possible up there, it would be a non-tropical low. Best conduit to early season warm seclusion/sting jet dynamics would be via a WPAC typhoon riding an augmented E-Asia-NPAC jet.
Good grief, is there any warm season pattern that can produce a negative departure here in JJA now?
Western ridging used to do the trick but not anymore with how dominant the Bermuda High is in the 21st Century.
