....THERE IS A MARGINAL RISK OF EXCESSIVE RAINFALL ACROSS PORTIONS
OF THE LOWER MISSISSIPPI VALLEY TO THE CENTRAL GULF COAST...

12Z guidance continues to show showers and thunderstorms
developing on Monday and growing upscale in areal coverage and
rainfall rates from Monday night into early Tuesday.  Shortwave
energy will spread into the Lower MS Valley and Central Gulf Coast
region in association with an elongated southern stream jet
sweeping eastward along the U.S. border with Mexico.  This allows
for increasing flow of Gulf moisture at low levels to be drawn
inland.  One concern continues to be that moisture flux standard
anomalies barely exceed 1 standardized anomaly greater than
climatology, but precipitable water values at or above 1.75 inches
and MUCAPEs on the order of 1000 J per kg hugging the Gulf coast
suggests localized rainfall rates of 2-3 inches within 2-3 hours
possible...especially where quasi-linear segments off the Gulf
train. This scenario could pose an isolated flash flood risk,
mainly across urban and other poor-drainage areas. As a result, no
changes were made to the previously issued Marginal Risk area.
