South America

Weather Underground Forecast for Thursday, May 22, 2008.

Unsettled weather pattern is expected across the southern South America over the next few days. A low pressure system off central Chile will push ashore and gradually weaken throughout the day. As a result, expect precipitation rates to be the highest across central Chile through Friday morning. Central Argentina can expect light to moderate precipitation continuing Thursday, slowly tapering off Friday morning. In addition, moist onshore flow will keep a threat of precipitation across far southern Chile and Argentina.

Farther north, isolated afternoon and evening thunderstorms are expected in northern Argentina, Uraguay and far southeastern Brazil as a weak front remains in place. Apart from that, typical daily thunderstorms will continue across much of the northern South America.

Temperature wise, Buenos Aires will remain in the mid-20s Thursday, with a chance of rain. Santiago can expect highs in the mid-teens and rain is likely. Rio De Janeiro will see highs rising to 30C and Brasilia should see temperatures rising into the mid-20s.
