...There is a slight risk of severe thunderstorms for portions of
Montana and the northern Plains...
...Heavy rain possible over the Gulf Coast and Mid-Atlantic...
...Heavy rain possible over portions of Arizona and New Mexico...
A near-stationary boundary will remain draped from the Carolinas,
across the Gulf states and into the southern Plains.
Tropical moisture will pool along the boundary with a weak
upper-level low over Florida that will aid in producing showers
and thunderstorms from the Southern Plains to the Southeast.
Rainfall intensity will increase during the afternoon and evening
hours, which will increase the risk for flash flooding, especially
along the central and eastern Gulf of Mexico Coast.
An upper-level impulse over the Northern Rockies will move
northeastward into Canadian Prairie and merge with a boundary
moving southward over Central Canada by tonight. Once they merge
the front will extend from the Hudson Bay through the Upper
Midwest and westward to Northern Rockies. Scattered showers and
thunderstorms will develop along and ahead of this boundary- some
will likely become strong to severe. Additionally, bursts of heavy
rain will be possible along the International border of
Washington, Idaho and Montana increasing the threat of flash
flooding. Onshore flow from the Pacific Ocean will help produce
rain over parts of the Pacific Northwest through Tuesday.
Monsoonal moisture will continue to stream northward into the
Desert Southwest. A combination of the ample moisture and daytime
heating will generate scattered to widespread convection for the
Southern/Central Rockies and the Southwest/Eastern Great Basin.
Localized heavy rain is forecast and flash flooding will be
possible.
