Bermuda High - Azores High Setup in the Extended Range

[gatorcane]

Already looking "summery" out there, note the Bermuda High-like feature and Azores High-like feature at 120 hours, with a weakness inbetween. This setup is almost what you would see just about anytime in the summer months also. The Azores High would be nudged SSE some...closer to the Azores than this setup.

Yes I see cycloneye observed the same thing I observed with strong high pressure building in across the entire northern Atlantic basin

Still, it does not appear too strong overall but then again, I have not seen any pressure anomaly maps as of late. Anyone know where to find those?

I'am very interested also by a pressure anomaly map;i never found such a map...Does it exist????

I just checked out the ECMWF model. It shows H5 ridging over the Western Atlantic and Florida (Bermuda High) to not budge for 240 hours with various "cut-off" systems shooting NE out out of the rockies towards the Great Lakes, along the NW periphery of this powerful ridge.

To go from constant East Coast CONUS troughiness bringing in a few rare freeze events all the way down into interior Miami-Dade area of South Florida, to this long-wave pattern of persistent ridging is pretty amazing. Also, 240+ hours of ridging along the Eastern CONUS is quite impressive for even the middle of summer let alone late April.

Of course this long-wave pattern means nothing for the setup come hurricane season -- but as we get closer we will certainly be looking closely at the 500MB flow as it usually gives a good gauge as to the steering currents of tropical systems.

The ECMWF 12Z just out a couple of hours ago -- shows the Bermuda High ridge holding strong all the way through 240 hours folks....

That ridge extends through FL into the Eastern GOM, just like it has for the past couple of weeks now.

Reminds me alot of 2004 at this time.....

ECMWF 240 hours:

This long-wave pattern with such a staunch Bermuda ridge would steer tropical systems far to the west and would prevent recurvature (at least those systems developing west of about 55W), namely, those systems that do not escape to the east of the ridge through the spine of the Atlantic.

We are lucky to have this pattern now when no threats exist. This long-wave pattern should inevitably break-down...and be replaced with more troughiness along the Eastern CONUS.
