Synopsis: Broad inverted trough of low pressure extends N from near 19N towards 30N between 50W and 38W this morning, weakening and moving W thru today to between 55W and 43W by tomorrow morning. Trough then dissipates thru early 14/12 while moving SW towards 20N and 60W. Strong cold front extended SW from near 40N/50W towards 25N/63W by early 14/12 will slowly move E towards 45W from 25N to 40N, blocking ridging from building SW across W central Atlantic during this time. Conclusion: Scattered to widespread squall/shower activity associated with weakening trough is expected across grids JJ and KK later today into tomorrow, though no heavy squalls are forecast at this time as trough will be weakening and breaking down. As trough axis slides across grids thru next 2 days, winds will tend to weaken and become less enhanced from E to W across all girds. T = 12/12 0600 UTC SHWRS/SQUALLS* IN ALL GRID AREAS JJ:
