Synopsis: A broad inverted trough of low pressure currently extending N from 20N to 30N and from 50W to 40W. This trough will dissipate thru early 14/12 over the next several days while moving SW towards 20N and 60W. Behind this, high pressure ridging will build W over the next few days and will remain in place thru the 15/12. Conclusion: Trade shower/squall activity will linger over the next few days as inverted trough weakens, especially along grids JJ and KK. As ridging strengthens, winds will freshen, particularly in S grids PP, QQ and QQ thru the 15/12. As trough weakens, squall activity will become less enhanced along all grids.
