The northerly flow across Alabama yesterday and overnight resulted in quite a gradient in temperatures and dew points. This morning dew points were in the middle 50s in the Tennessee Valley while they were still in the lower 70s in Southeast Alabama. Slightly drier air aloft managed to erode much of the cloudiness across the state overnight. Look for the best chances for showers to once again be across South Alabama where moisture values remain the highest.

Aloft the elongated upper ridge will be subdued somewhat on Monday with the passage of a fairly strong trough moving across the Great Lakes. The trough should extend its influence far enough south to allow good chances for widespread showers and storms across Central Alabama. High pressure to the northeast of Alabama will allow moisture to return northward on Monday, too, adding to the potential for our best chances for rain in the week ahead.

The fast moving trough will quickly exit across New England by Tuesday as the overall upper flow becomes northwesterly as the long wave trough sets up across the eastern third of the Nation. The development of this trough should begin the drying process with drier air in place for the middle and latter part of the week ahead. By the end of the week, the upper ridge over the western US will migrate eastward allowing our temperatures to warm up into the upper 80s for Friday and Saturday.

At the beach, typical late summer weather continues along the Alabama and Northwest Florida Gulf Coast today and for most of the week ahead. Highs will be in the upper 80s, overnight lows in the upper 70s. There will be a mix of sun and clouds, with scattered showers and storms. You can expect 4 to 6 hours of sun each day with daily chances for scattered showers.

Tropics are a tad active. Edouard is expected to achieve hurricane status sometime today while it churns northwestward in the open Atlantic before turning more northerly on Tuesday. In the Gulf of Mexico, the area of disturbed weather has become quite diffuse as it moves steadily westward across the Central Gulf with little potential for development. An area of disturbed weather west of the Cape Verde Islands shows little signs of development.

The GFS long range progs continue to keep the idea of general troughiness across the eastern US into late September. But there is also the depiction of some tropical mischief for the Gulf near the end of the month. But you know how this can change that far into voodoo country.
