A weakening cool front will slide slowly southward and dissipate in Acadiana this weekend allowing for a chance of scattered showers and a few thunderstorms. Rain chances should stay near the 20% range through Sunday.
Daytime highs will not be as hot as recent days with highs closer to the lower 90s while overnight lows persist in the lower 70s.
Rain chances will likely stay in the slight chance category through early next week but could improve later next week as remnant moisture from Ingrid gets drawn northward through South Texas and possibly eastward by an approaching upper level trough from the north.
Meanwhile, Tropical Storm Ingrid with 45mph winds is expected to meander slowly northwestward toward the Mexican coastline through this weekend. Some strengthening of this system is possible as long as the circulation center stays far enough offshore from the coast.
No impacts from this storm are expected in Acadiana/Southern Louisiana other than a slight increase in tides (about 1 foot) along the coast later in the weekend.
Ingrid will likely bring rainfalls in excess of 10-15 inches across portions of Mexico with flash flooding and dangerous mudslides likely in higher terrain.
Elsewhere, Gabrielle in the North Atlantic has weakened to a remnant low but will bring the threat of heavy rains and gusty winds to the Canadian Maritimes this weekend.
In the far Eastern Atlantic, Humberto with 50mph winds late Friday will continue to slowly weaken in the near term but could re-intensify in a few days as it moves northward into the North Atlantic.
There are no other suspect areas in the tropics at this time, although the long-range models do keep the Bay of Campeche, the Northwest Caribbean and possibly the Southeastern Gulf unsettled through late this month.
