...There is a Slight Risk of severe thunderstorms over parts of the
Central High Plains, Central Gulf Coast, and parts of the northern
Mid-Atlantic/Central Appalachians through Monday morning...
...Building heat, as well as potential fire danger, is forecast for much
of the West...
Multiple weak fronts and some upper-level impulses will produce scattered
showers and thunderstorms east of the Mississippi River to the East Coast
through the remainder of the day. Meanwhile, moisture streaming into the
Central High Plains and a weak front will trigger showers and
thunderstorms over parts of the Central Plains and Southern Plains. The
SPC has issued a Slight Risk of severe thunderstorms over the Central High
Plains, Central Gulf Coast, and parts of the northern Mid-Atlantic/Central
Appalachians through Monday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes. On Monday, showers and thunderstorms will
develop over parts of the Northeast and along the Gulf Coast into the
Southeast. The same general areas will be active on Tuesday as well.
Meanwhile, in the West, heat will build through Tuesday as an upper-level
ridge expands eastward over the Rockies and the Southwest. Therefore,
excessive Heat Watches and Warnings and Heat Advisories are in place,
especially from Monday onward for portions of California, the Desert
Southwest, and the Great Basin. Hot temperatures in the 90s and even into
the 100s will spread eastward into the Northern High Plains into Tuesday.
Record high temperatures are expected to be widespread across the Desert
Southwest, Intermountain West, and the Rockies through Tuesday evening.
Given the heat, dry conditions, and gusty wind, an Elevated Risk of fire
danger is in place in the Great Basin for the rest of Sunday into Monday
morning, with a Critical Risk for portions of Nevada and Utah on Monday.
The Pacific Northwest and Northern California will have light rain as a
front over the Pacific Northwest move slowly eastward to Great
Basin/Northern High Plains by Tuesday evening.
