...Severe thunderstorms and locally heavy rain possible today for portions
of the Mid-Atlantic and Northeast...
...Above average temperatures expected to shift east from the Pacific
Northwest to the northern Rockies...
A frontal system will bring scattered to numerous showers and
thunderstorms to much of the Mid-Atlantic and Northeast today. Some
thunderstorms could be severe; please refer to products issued by the
Storm Prediction Center for further details on the severe weather threat.
Locally heavy rainfall is also possible. Another round of scattered
showers and storms is possible on Wednesday for the same areas as a
secondary cold approaches the region and an upper-level disturbance passes
overhead. As this secondary cold front passes through Wednesday night and
Thursday morning, high pressure will move into the Great Lakes and
Northeast behind it, ushering in a drier and somewhat cooler air mass.
Farther south, the trailing end of the frontal boundary will linger as a
stationary front from Texas to the Southeast, producing scattered showers
and thunderstorms over a wide area today through Thursday.
The ridge of high pressure aloft that has resulted in temperatures soaring
well into 90s for interior portions of the Pacific Northwest will begin to
move east today. Temperatures will once again rise into 90s across the
interior Northwest and northern Great Basin today. The Northwest will cool
by Wednesday as an upper-level trough begins to move into the region, and
a weak cold front ushers in a cooler Pacific air mass. The above average
temperatures will shift east on Wednesday along with the upper-level
ridge, and high temperatures will rise well into the 70s and 80s across
much of the northern Rockies, 10 to 15 degrees above average. Scattered
showers and thunderstorms will be possible as well from the Northwest to
the northern Rockies, especially ahead of the aforementioned cold front as
it moves inland on Wednesday and Thursday.
