A rather strong weather system will move in just in time for election day. The outcome of this storm is something rare here these last few days. . . rain ! The rain will be measurable as many important variables are finally coming together overnight Monday and Tuesday morning. A frontal boundary coupled with ample gulf moisture and a deep upper level trough will swing through the area as many of you will be out at the polls. Right now the odds of rainfall are 70% with some of these storms reaching severe levels. Rainfall amounts especially along the coast could as much as 1 to 2 inches.
The area from San Antonio to Bryan to Houston has a slight chance of severe weather since upper level shear will be moderate. The most likely types of severe weather will be high wind and small hail from a series of squall lines moving through the area Tuesday.
The initial squall will come in advance of a cool front early Tuesday morning. An upper level low may keep rain chances going as the polls close late Tuesday evening. Cooler drier air pushes in Wednesday as the elections results are finalized. Unless you were an early voter the odds of getting wet on election day are running very high.
