Numerous Showers Once Again

| July 15, 2018 @ 6:32 am

Very little change in the overall pattern affecting the Southeast US, so I expect to see numerous storms develop once again in the heat of the afternoon as highs climb into the lower 90s. Heat advisory is in effect through this evening for the western counties of Alabama from Demopolis to Florence. Precipitable water values remain high, so with little movement to most of the storms, localized flash flooding could once again be an issue. And be sure to respect the lightning threat with these storms, too.

As was noted yesterday, we could see a bit of a change for the northern half of the state of Alabama as the upper ridge slides westward to become situated over the southern Rockies by Wednesday. This will turn our upper flow to more northwesterly as a broad trough develops over the eastern half of the country. Storms will remain numerous Monday and Tuesday, but with some drier air as depicted by the precipitable water chart flows into North Alabama, we should see a significant drop off in storm coverage. Highs will remain in the lower 90s, but Wednesday some spots may only see highs in the upper 80s.

A fairly strong upper trough will slide across the Great Lakes Thursday through Saturday which is expected to drag a weak cold front into the Southeast US Friday and Saturday. This will once again bring the chances for storms up somewhat after a couple of days of lowered chances. Highs stick pretty close to climatological averages with values from 89 to 92.

Looking out into voodoo country, the GFS remains convinced that there will not be any extreme heat across the eastern half of the country as the upper air pattern remains with a weak trough while the upper ridge remains in the vicinity of the Four Corners area. This means highs 90 to 92 with the likelihood of daily chances for scattered showers.

The Atlantic Basin is fairly quiet with the exception of the remnants of Beryl which is likely to weaken to a depression by Monday.
