..Dangerous heatwave continues across the central and eastern
U.S. through the end of the week...
..Severe weather and heavy rain threats continue across the
Plains, Upper Midwest, Southeast, and Northeast the next few
days...
..Critical fire weather conditions continue over parts of the
Four Corners through Friday...
A strong upper-level ridge will remain anchored across the central
and eastern U.S. through the weekend, supporting a prolongs and
dangerous heatwave from the Midwest into the Ohio Valley,
Mid-Atlantic, and Northeast. Widespread highs within the mid 90s
to low to mid 100s, combined with dewpoints int he 70s, will
produce peak heat indices between 100-115 degrees. Numerous daily
temperature records are possible, while warm overnight lows in the
70s to 80s will provide little relief, bringing Major to Extreme
HeatRisk conditions across the Midwest into the East Coast. These
conditions can bring an increased risk for heat-related illness,
especially for vulnerable populations and those without adequate
cooling. Several areas across the Mississippi Valley, Great Lakes,
Ohio Valley, and Northeast have issued Extreme Heat Warnings and
Heat Advisories through Friday. Otherwise, much of western U.S.
will remain cooler as the upper-level trough continues to bring
below normal temperatures.
Along the northern periphery of the ridge, a quasi-stationary
frontal boundary extending from the northern Plains into the Upper
Midwest and Great Lakes will act as a focus for multiple rounds of
showers and thunderstorms. A moist and unstable mass, combined
with passing shortwave disturbances, will support organized
convection capable of damaging winds, large hail, and excessive
rainfall. A Slight Risk of excessive rainfall remains in effect
across portions of the Northern Plains, Upper Midwest, and Great
Lakes for Thursday into Friday, where repeated thunderstorms may
lead to scattered instances of flash flooding. In addition, there
is a Slight Risk of severe thunderstorms across the northern
Plains into the Midwest and Great Lakes, where strong to severe
storms may be possible. In addition, some shortwave disturbances
may bring isolated strong to severe thunderstorms across the
Northeast and parts of the Tennessee Valley, with a chance for
damaging gusty winds associated with the storm. The severe weather
threat expands into the Mid-Atlantic on Friday, as the shortwave
trough and unstable air may support organize convection with
chances for damaging winds and large hail.
Farther south, deep tropical moisture will sustain scattered to
numerous diurnal thunderstorms from the Gulf Coast into parts of
Southeast and Florida. With high rainfall rates and slow-moving
storms, isolated flash flooding may be possible, particularly in
urban an poor drainage locations. Critical fire weather conditions
will persist in parts of the Southwest, where low relative
humidity, gusty winds, and critically dry fuels will continue to
support rapid wildfire growth and extreme fire behavior.
