Precipitation:

Rain will occur today in association with two low pressure systems. One will be moving from West to East Texas and the other will be diving south from Montana to Iowa. Heaviest rainfall in the United States exceeding two inches may occur in East Texas. Heavy snow may occur in South Dakota in association with the northern low pressure and frontal system. Severe thunderstorms will be possible from Central Texas through Georgia with the greatest threat in the southern half of Louisiana. Tornadoes, large hail, and severe winds are possible.

Temperature:

Temperature will be moderate over much of the southeastern United States today. Dewpoint temperature will be high there.

Challenge Questions: What is dewpoint temperature? Why do you think that the thunderstorms and greatest rainfall are associated with regions of high dewpoint temperature?
