...Strong cold front to spark showers and thunderstorms and possible
severe weather across portions of the Northeast through this evening...

...Strengthening frontal system will bring widespread showers and
thunderstorms from the Intermountain West and Rockies to the Plains over
the next couple of days...

...Dangerous heat continues across the south-central U.S. through
midweek...

Moisture streaming northward ahead of a strong, well-defined cold front
pushing across the Northeast will set the stage for scattered showers and
thunderstorms this afternoon and evening. Some of these storms could
become strong to severe, with damaging wind gusts the primary threat. Once
the cold front clears the East Coast, a sprawling bubble of high pressure
will help usher a cooler and drier air mass into the region.

Meanwhile, a low pressure system is expected to gain strength as it tracks
from the northern Rockies to the northern Plains through the day on
Monday. This complex system will bring a couple days of unsettled weather
from the Intermountain West and Rockies to the central and northern
Plains. Plenty of moisture streaming northward ahead of this frontal
system will support widespread showers and thunderstorms, some of which
could produce severe weather and heavy rainfall.

Across the south-central U.S., an upper level ridge will continue to focus
dangerously hot weather with highs well into the 90s and low 100s.
Combined with little relief at night, several days of major to extreme
HeatRisk are likely, which would increase the likelihood of heat-related
illnesses.
