...THERE IS A MARGINAL RISK FOR EXCESSIVE RAINFALL FOR PORTIONS OF
THE WESTERN GULF AND LOWER MISSISSIPPI VALLEY...


Numerous showers and thunderstorms are expected to fire up across
Texas and portions of the Lower Mississippi Valley during this
period as warm air advects northward ahead of an approaching cold
front. Areal averages of 1 to locally 3 inches will be possible,
with the best potential for the highest amount to focus near the
Gulf Coast. A Marginal Risk area is in effect for eastern Texas,
southeast Oklahoma, southern/central Arkansas, western Mississippi
and most of Louisiana.
