...More active weather across the mid sections of the nation, with
additional rounds of thunderstorms, heavy rains, flash flooding
and severe weather...

...Heat to continue across the Southwest to South Texas and much
of Florida, while building across the inland valleys of
California...

...Cooler than average temperatures for the Plains and large
portions of the eastern U.S. through early this weekend...

A tumultuous weather pattern sparking several rounds of robust
thunderstorms is set to continue throughout much of the central
and south-central United States. The atmospheric ingredients in
play for the next serving of severe weather include an upper
trough with embedded shortwaves crossing the Rockies today,
multiple frontal boundaries draped across the Great Plains, and
ample atmospheric moisture content lifting northward from the
western Gulf of Mexico. Additionally, a reemerging dryline over
the southern High Plains will help spark strong storms this
afternoon that are forecast to progress eastward tonight over the
southern Plains. These thunderstorms may contain large hail and
damaging wind gusts, with the locations most likely impacted
including the Texas Panhandle and parts of west Texas. A broader
threat for isolated severe weather stretches throughout a majority
of the central and southern Plains. Intense rainfall rates are
also possible and can lead to flash flooding where storm motions
are slow. Currently, the scattered flash flood threat includes
much of the central/southern Plains and ArkLaTex region. The
active weather and clusters of redeveloping thunderstorms are then
forecast to gradually slide eastward on Friday as an area of low
pressure pushes across the Red River Valley of the South.
Additional chances for damaging wind gusts and large hail exists
across central and eastern Texas, as well as into the Lower
Mississippi Valley. Flash flooding also remains a concern for the
last day of May across the southern Plains and Lower Mississippi
Valley. Wet weather is anticipated to expand to start the weekend,
but with less focus for severe weather as thunderstorm chances
stretch from the Ohio/Tennessee valleys to the Great Plains.

Storminess over the central U.S. will keep high temperatures below
average to end the week, while a potent high pressure system over
the Lower Great Lakes and Ohio Valley also offers refreshing
afternoon temperatures in the 70s for large sections of the
Eastern United States. Summer heat will be continue to be found
across the Southwest and Southern Tier. Muggy highs into the
mid-90s are forecast across the central/southern Florida Peninsula
until a cold front enters on Saturday and offers some much needed
relief in the form of persistent northeasterly flow. Upper 90s and
low 100s are anticipated to stretch from the Southwest to far
western and southern Texas through the weekend. Heat will actually
build further north into the Great Basin and interior California
valleys as well, but not quite warm enough to approach daily
records. If spending time outdoors in these regions, be sure to
follow proper heat safety.
