Just how STRONG is the EC trough? See for yourself.

Pretty impressive loop SF! So do you think this pattern will change in time for fall?

MR/LR model consensus are indicating a pattern change in about 5-7 days as the trough is squelched ... According to model consensus, the Bermuda High retrogrades westward and the Plains Dome to squelch out the EC trough, however, there may be a piece of a 500mb low which cuts off from the main flow around the TX/LA area.

I would think we are about to set a record here for coolest summer. I only remember two days when the temp hit 90, and that was sometime last month! Last summer was cool too, but nothing compared to this year!

The trough seems to act strange. It's not bringing rain to Myrtle Beach.

Blame that on local effects. The seabreeze boundary as it blows inland from the water during the afternoon. The differential heating over the land creates a cooler boundary of air from the water and blows it inland, and right along it, showers and thunderstorms can initiate from it.

The pattern setup right now has that seabreeze front going too far inland for Myrtle Beach to see showers late in the evening today.

Oh Ok, Didn't know that. I didn't know that though is linking with the
seabreeze. Thanks, SF.

Yep. Probs with flooding here again tonight in large part due to location of the right entrance quad...nicely depicted on the WVL. S/w rotates in then stalls out. Now getting old.

Second issue has been the Bermuda High builds in then becomes displaced. That's been going on for weeks and while the High should retro, that may not stick.

Interesting summer.

Strange summer...it still hasn't reached 90° degrees at my home west of Atlanta yet (only one day at ATL).
Tonight it honestly feels more like September 10th than early August..it's been that way for several days (only reached 84° today, low was 66° this morning).

Currently it's 69.6° with 90¼ humidity -- a 67° dewpoint isn't bad for August 9th in Atlanta....I've seen it much worse.

Interesting point, Scott. Some indications, particularly the EURO suggest the building ridge, although quite strong (594dm), it may be a dirty ridge, with a lot of leftover moisture especially the Southeast. The Northeast/Mid-Atlantic looks more favorable for a warmer, drier regime.

I also noticed what looks like a potential for a cut-off 500mb low setting up somewhere in the South Central Plains indicated by some of the MR.

The trough brought T'Storms into Myrtle Beach overnight last night, As
well as some rain.
