..Severe thunderstorms and flash flooding continue across
portions of the Central U.S....
..Dangerous Heat Persists in the West and Southern Plains...
A frontal boundary stretching from the Northeast to the High
Plains will maintain the chances for showers and thunderstorms
today as it interacts with a seasonably moist and unstable airmass
entrenched across the Central and Eastern U.S. Within this broad
area, two corridors are being monitored for potential flash
flooding and severe weather later today: the Mid-Atlantic from
DelMarVa to the Coastal Carolinas, and the region spanning from
the mid-Mississippi Valley to the High Plains. By this evening,
the frontal passage through the Eastern Seaboard should clear out
the thunderstorm activity, although unsettled weather will linger
in the Plains overnight as thunderstorms merge into organized
complexes. The next two days look equally stormy across the
Heartland and also Upper Midwest as another frontal system in the
Northern Tier reinforces the original frontal boundary. Portions
of the Great Basin and Southwest can also expect an uptick in
daily showers and thunderstorms this week, owing to an influx of
Eastern Pacific moisture on the northern flank of a strong
upper-level ridge.
This upper-level ridge will sustain the intense heat across the
West, Southwest, and Southern Plains for the next three days,
where a handful of Extreme Heat Warnings and Heat Advisories are
in effect. In contrast, a cooler-than-average Canadian air mass
behind the Northern Tier system will spread from the Northern and
Central Plains towards the Northeast, bringing below-normal
temperatures to much of the region through Thursday.
