Showers and thunderstorms remain in the forecast over the next few days. While mornings start dry, the rumblers will bubble up by midday and last into the late afternoon.

Today and Tonight: This is likely to be the most active day of the week. Showers and thunderstorms will be widespread. Some locations may even receive multiple showers or storms. Heavy rain, a quick inch, and frequent lightning will be possible in several storms and some minor street flooding could result. Timing does not look ideal as storms could be around to soak the interstates in time for the late commute. A better spread of rain will lead to lower top out temperatures with many areas barely hitting 90 degrees. Overnight, some scattered showers may persist, especially in coastal areas, with lows in the mid 70s. 

Up Next:  Wednesday will offer up scattered showers and thunderstorms as well. Highs will be in the low 90s. Thursday through Sunday will find slightly fewer showers and thunderstorms around the area. We’ll again term them isolated showers and storms. Highs will be in the low 90s with lows in the mid 70s. 

THE SCIENCE:

Forecast Discussion: An inverted trough stretching from the Central Gulf of Mexico to the Coast will move from east to west, from the Florida Panhandle to Western Louisiana through mid-week. This trough will denote a shallower, cooler atmosphere and this weakness aloft will lend to more instability and a more unsettled weather pattern. Particularly Tuesday as a solid area of vorticity is expected to move across the region, showers and thunderstorms will be more widespread. In fact, rather than some locations getting rain and others not, there is actually a better bet that some locations see multiple storms on Tuesday. More of the same is expected for Wednesday. Storms will have a slow, erratic west to west-northwest motion and could produce downpours and frequently lightning. With high dew points and precipitable water, storms could leave behind a quick inch or so of rain prompting some nuisance street flooding. By late week, the trough will break down but a weakness in between two upper ridges –one in the Atlantic and one in the Southwest U.S. – will remain. As a result, will action may settle somewhat, at least isolated showers and storms, 20-40 percent coverage, will be maintained in the forecast each day through Sunday. There are some signs that a ridge will return bringing warmer and drier conditions to kick off August.
