Yeah mid latitudes are cooling and far north Atlantic is warming. MDR is still cold though

New OSPO SSTA map out for April 9. MDR appears warmer in west, and northeast, little change elsewhere

It is early but looking at the Atlantic compared to last year at this time (see above map for 2018 and below for 2017), seems we almost have the reverse where this year we have cooler than normal MDR and warmer than normal subtropical Atlantic. That could mean back to another season of systems which really don't take off until moving out of the MDR/tropics similar to what we saw in years prior to 2017:

Yeah I’m not too impressed with the signals I’m seeing right now for the upcoming Atlantic Hurricane Season. I know just like last April things can change on a dime but I’m slowly starting to become less bullish in what I think will happen during this years Atlantic Hurricane Season. A quantity over quality season seems reasonable at the moment. Of course with all the devastation and destruction last season brought I’m sure many will be fine with just that.

I just want that anything that forms in 2018 season goes to open waters and have a free landfalling season.

It doesn't matter how much destruction the previous season brought because I always desire a low impact season on land. However, last season's high level of devastation & destructiveness re-enforces that desire. So, hopefully we get El Niño. Also, because of the desire for quiet, I'm not crazy about the use of the word "quality" by some to refer to a season with many strong and/or large hurricanes because the word "quality" usually implies something of a positive nature.

There being many strong hurricanes doesn't always mean a more impactful season- look at 2010 for example, with many out to sea tracks. And I'm sure quality is referring to the strength of the storms, and not that they are a positive thing for those affected.

I know it doesn't. But if we don't have many strong hurricanes at all, that in itself would help our chances of having low land impact.
I realize that's what's meant by quality but I'd prefer the word "strong" because "quality" usually refers to something desirable. One meaning of quality: "the degree of excellence of something". Excellence implies something good.
Anyway, I'm hoping for El Niño because that would increase the chance for fewer storms as well as weaker storms on average. We'll need to get past the spring barrier before I can have confidence in what ENSO we'll likely have. Many including myself thought we were going to have El Niño last season and look what happened.

Unfortunately As wxman57 stated previously significant impacts from El Niño this season appear unlikely. I think there’s way to much focus on water temps in April I think the Atlantic will be ready come ASO to start pumping out hurricanes.

It appears that the MDR is warming up a little, as well as the waters near and east of Greenland. This probably doesn't mean too much for the hurricane season, since it's only April and the SST anomalies could still change a lot, but it would be interesting if the -AMO look would flip to a more +AMO look.

I also noticed the significant cooling in the gulf. Is that unusual?

Probably caused by the recent frontal passage

I wouldn't pay too much attention to it. You can see from recent satellite loops that cloud coverage coupled with anomalously strong winds stirring up the surface are the primary factors:

That map is just showing the 7 day change in anomalies. The above normal anoms have abated somewhat over the past week but the Gulf remains near to somewhat above normal overall. Not that it matters for the Gulf anyway...it always has sufficient OHC when it counts.

I really don't trust the CDAS SSTs estimates, it shows at least a 2 deg C drop in SSTs in the BOC during the past 7 days but if you look at the buoy 42055 in that area it only shows 1 deg C drop during the past 7 days.
