100F Heat!

By  | 

Desert air from the Mexican Plateau has arrived aloft, and is blocking a weak front over central Texas from moving south into our area. Any showers that form over the high terrain of northeastern Mexico quickly fade away as the gulf air fueling the showers is not buoyant enough to rise high enough to maintain the tall rain clouds. The desert air will become more pronounced above, and will mix close enough to the surface to raise our temperatures to 100F. The desert air above will retreat a bit to the south by Sunday with a slight chance Sunday night or Monday that a shower from the mountains could reach our area.

I'm expecting mainly sunny Thursday through Saturday, high around or a little above 100. Partly cloudy Sunday through Wednesday, highs in the mid to high 90's. A slight chance of a shower Sunday night or Monday.
