Looks like the trough will weaken for a while...but then re-establish itself by mid to late next week. That's why I have very preliminary concern for FL again.
You are right about the persistant trough over the East. A very winter-like pattern...extremely unseasonable for August. Global warming, you know ;)
I was wondering earlier this week if we would just see a conveyer belt of these things all season. The way the trough has persisted I haven't completely disregarded the notion.
Let's hope TD 5 goes a bit north and tracks across Cuba lengthwise.
