...Severe weather and heavy rain to threaten the northern High
Plains, Midwest, and Great Lakes ...

...Summer heat to stretch from coast-to-coast by mid-week...

...Elevated to Critical fire weather conditions across the Central
Great Basin today...

A passing frontal system over the North Central U.S. is
responsible for showers and thunderstorms marching across the
western Great Lakes this afternoon. They will continue on their
easterly track through the Great Lakes tonight and reaching
portions of the northern Mid-Atlantic by Tuesday morning. In wake
of this system, an upper-level disturbance passing through
southern Canada will work in tandem with a stalled front over the
Northern Plains and Upper Midwest to trigger additional showers
and storms late Tuesday. With better jet dynamics aloft, severe
weather is likely with damaging winds, large hail, and tornadoes
all possible. Rainfall rates could also be quite high with
localized flash flooding possible. Elsewhere, hit-or-miss showers
and storms should be found across much of the South; from Texas to
Florida. High pressure over the Southeast and Pacific Northwest
through mid-week ensures an otherwise mostly dry pattern across
the Lower 48.

As meteorological summer kicks off today, so too will an expansive
dome of summer heat which quickly moves west to east over the next
couple days. High temperatures will soar into the 90s across the
Northern/Central High Plains and Midwest through Tuesday with
triple digit heat entrenched across the Desert Southwest.
Following a cool Monday, the West Coast should see temperatures
return to summer-like levels. The East Coast manages one more day
of seasonally cool temperatures Tuesday before considerably warmer
and more humid conditions arrive on Wednesday. In addition, a
critical risk for fire weather continues today in the central
Great Basin. Elevated risks for fire weather extend east into
western Colorado and on southward into the Lower Colorado River
Valley.
