From my vantage point, we had a H - B - or whatever ECS 5 days ago on GFS that promptly vanished from sight on said GFS very next run...
Only to be given a heartbeat (not saying at the 'get your affairs in order' level) at the 12Z today but notably, NOT vanishing on the very next run... and then some Euro support thrown in for good measure.. Details TBD, but my interest is ratcheted several notches and what looked to be a boring 14-day stretch of ho-hum fraught with trapped Boo hoo peninsula energy, has now - behold - given rise to something to check in and track. This is IMHO, good.
