...Severe thunderstorms and locally heavy rain possible for portions of
the Southeast and Gulf Coast states...
...Continued above average temperatures expected for the Interior Pacific
Northwest and Great Basin...
An upper-level trough across will persist across the Great Lakes through
the next couple days. A series of cold fronts will affect areas from the
plains and the Midwest to the East Coast, associated with multiple
upper-level disturbances rotating around the system. A slow-moving to
stationary frontal boundary will bring scattered to numerous showers and
storms today and tonight from southern Texas along the Gulf Coast, and
across the Southeast. Some thunderstorms could be severe, especially
across the Southeast. Please refer to products issued by the Storm
Prediction Center for further details on the severe weather threat.
Locally heavy rain will also be possible. This front will linger into
Tuesday, with scattered areas of showers and thunderstorms expected for
much of the southern U.S. once again. Farther north, the northern portion
of the same frontal boundary will bring widespread showers and a few
thunderstorms to the Northeast today and tonight. On Tuesday, another
frontal system will approach, bringing another potential round of showers
and thunderstorms to the Northeast. By late Tuesday, yet another cold
front will cross the central plains and mid-Mississippi valley, producing
additional scattered showers and thunderstorms.
High pressure aloft will begin to shift eastward from the West Coast into
the Rockies through the next couple days. This will allow the above
average temperatures to shift east as well. Temperatures are forecast to
rise well into the 90s today and tomorrow for the interior Northwest, 10
to 20 degrees above average. Cooler Pacific air will begin to spread into
coastal areas of the Northwest on Tuesday as the ridge of high pressure
begins to shift east. By Wednesday, the center of above average
temperatures will shift to the northern Rockies, while the Northwest will
see a bit of a respite from the hot temperatures as a Pacific frontal
system approaches.
