7/18 – Rob’s “Round Three” Heavy Rainfall Forecast

The constant showers/t-storms coverage will begin to decline over the next few days…but that only means more sun, heat and humidity.

Today will bring another round of potentially HEAVY RAINFALL,

with Thursday being a transition day as temps will climb into the lower/mid 90s into early next week. A few locations may approach the upper 90s as well by the weekend. This will make for some oppressive conditions Friday through Monday and possibly Tuesday. By Tuesday, the upper trough along the east coast begins to get another shot of energy on its west side which will try to develop a broad surface low-pressure near the Fla panhandle. The upper trough maintains a surface trough in the area Monday and Tuesday but the dry air that has moved into the area by that time, it may preclude most showers/t-storms development.

Global models show a large amount of dry air that is cool at first but gets modified quite a bit as it moves south. But the dry air stays intact, at least from a model stand point. This new reinforcing front would bring dew-point temps in the low to mid 60s by mid to late next week. This may not sound like a big deal, but this is the end of July and we are deep into summer by this time which makes this fairly rare.
