A low pressure area with associated upper level trough currently off the west coast of South America will decouple into a closed low that moves poleward south of Tierra del Fuego and a trough that will dig all the way into the subtropics and come ashore during the day Friday. The upper low will get absorbed into the westerlies but the trough will hang around the entire weekend, before more short wave energy comes ashore on the west coast Sunday night and forces the longer wave off the east coast. The short wave passes north of El Calafate while a large oblate low pressure area passes by to the south, leaving the upper flow Southern Argentina mostly zonal and difluent with some possibility for wave on Monday.
