9/17 – Rob’s “Friday-Eve” Morning Forecast

Other than the departure of Sally from the southeast U.S., the upper pattern doesn’t really change a lot through Saturday night. Weak upper troughing oriented from NW to SW is keeping southwesterly mid-level flow across the area. Water vapor satellite imagery shows a pretty good slug of moisture riding up toward the area. This is likely to produce quite a bit of cloud cover across the area beginning later today and continuing into the weekend. A few showers will affect the area Friday. Thunder will be limited north of an approaching cold front, a little more widespread to the south.

As long as the boundary remains offshore, we’ll be looking at some welcome cooler and less humid weather across the area beginning tomorrow. Likely the coolest spell of weather across the area since early May.

Upper level high-pressure centered near northern Mexico will shift towards central Texas and eastern Oklahoma. At the surface, high pressure will still be building in from the northeast. This will generally keep the area dry and on the cooler side. However, the local area will protecting us from an area of low pressure that is still stuck in the western GOM. Some of the models move that tropical disturbance north to northeastward into the central to possibly northern Gulf next week, but there is a lot of uncertainty at this point.
