Tropical Storm Barry is forecast to weaken to a tropical depression as it
moves slowly northward over Louisiana and Arkansas. Though wind will
decrease, very heavy rainfall will continue--rainfall accumulations of 6
to 12 inches with isolated amounts of 15 inches are forecast for
South-Central Louisiana, and rainfall amounts of 4 to 8 inches with
isolated amounts of 12 inches are expected for the remainder of the Lower
Mississippi Valley. Thus, a High Risk of flash flooding is in place today
across parts of Louisiana, with a Moderate Risk for much of Louisiana and
Mississippi and Southeastern Arkansas through Monday morning. River
flooding is also expected, and a few brief tornadoes are possible as well.
Elsewhere, the Storm Prediction Center has issued a Slight Risk of severe
weather for the Northern Plains and into the Upper Midwest. Storms could
also cause locally heavy rainfall and isolated flash floods. As a
quasi-stationary will remain over parts of the Northern Tier States,
showers and thunderstorms will continue over the area through Wednesday.
Farther south, scattered afternoon/evening thunderstorms are possible for
the Great Basin and Southwest into the Rockies and High Plains on Sunday
Cool high temperatures are likely in the Lower Mississippi Valley with
Barry, and record low maximum temperatures could be set there. Behind a
cold front moving across the Northwest, high temperatures will be 5 to 15
degrees below average. Elsewhere, temperatures will generally be at or
above average, and Excessive Heat Warnings and Heat Advisories are in
effect for portions of Arizona and California.
