Weather Underground Forecast for Saturday, July 05, 2014
The tropics will remain active over the Atlantic Basin on Saturday, while tropical cyclone development will wind down over the eastern Pacific. Hurricane Arthur is forecast to weaken slightly as it drifts northeastward over the Eastern Seaboard. During Saturday morning, Arthur will be located approximately 215 nautical miles east southeast of Boston, Massachusetts. This system is expected to be downgraded to a category 1 hurricane, with wind speeds ranging between 74 to 95 mph (64 to 82 kts). Arthur will bring heavy rain and thunderstorms to the northern Mid-Atlantic coast, as well as coastal New England. In addition, Hurricane Arthur will bring a threat of storm surge to coastal regions, which could lead to localized flooding. Thunderstorms will focus over eastern New England during the first half of the day, and will likely shift over Nova Scotia and New Brunswick during the afternoon and evening. In the eastern Pacific, Tropical Storm Douglas will be located roughly 550 nautical miles east of Cabo San Lucas, Mexico. Douglas is forecast to be downgraded to a tropical depression, with wind speeds staying below 39 mph (33 kts).

In South America, a warm, humid air mass will initiate strong to severe thunderstorms over southwest Colombia and northeast Ecuador on Saturday. In addition, an onshore flow from the Atlantic will push rainy weather across French Guiana, Suriname, Guyana, Venezuela and northern Brazil. To the south, a low pressure system will usher heavy rain across northeast Argentina, Uruguay and southeast Brazil. Further to the south, a trough of low pressure will slam into southern Chile. This system will push heavy precipitation across Patagonia.
