2-4 inches of rain possible for Wednesday; mainly for areas on the north shore

A cold front and upper disturbance are headed toward the area.

Be prepared for heavy rainfall at times on Wednesday.

A flash flood watch is in effect for St. Tammany and Washington Parishes as well as southern Mississippi.

However, the metro area may also see street flooding from heavy rains today. Once the front gets south of the coast, less humid air will reach the region making the August heat slightly more bearable for the few days.

There is the possibility of a low developing along the front, although models either don't develop anything or if they do, a very weak low would keep most of the rainfall to our east.

There is still a wave in the Caribbean that looks to move into the Gulf within the next few days.

Strengthening of this feature is possible being given a 50 percent chance of development by the National Hurricane Center.

Forecast models maintain that this wave or possibly Erin will move inland over the Florida panhandle by late Friday/early Saturday. This would keep LA and MS on the "dry side," but any jog to the west could mean additional rainfall.
