I was referring to Windguru prediction for week from Monday. No Big cold front pushing through midwest (Kansas to Oklahoma down to Texas) this week. Yes a bit of noth wind but not the cold front. It probably won't make it to Cozumel but if it does it will be short lived (1day). It is that big cold front high North winds that May make it down and form a true persistent Norte.
Looking at windguru cozumel this min, the wind shift is breaking down on 21st.
Windguru is a great tool but don't look too far ahead.
