..Strong to severe thunderstorms expected later today from the
Mid-Atlantic to the Northeast...
..Strong to severe thunderstorms with heavy rainfall threat
emerges over the central U.S. this weekend...
..Another day of heat advisories from the Mid-Atlantic to New
England before moderating by the weekend...
A couple of cold fronts moving from the mid-section of the country
toward the East Coast will be the impetuses for a couple of
focused rounds of strong to severe thunderstorms. The leading
cold front crossing into the Great Lakes, Midwest, and through the
southern Plains this morning will advance steadily into the East
Coast later today as a heatwave is forecast to reach its peak
along the East Coast. Temperatures are expected to soar once
again well up into the 90s this afternoon for much of the East
Coast and into the lower 100s from portions of southern Virginia
to North Carolina with triple-digit heat indices. Strong to
severe thunderstorms are expected later today from the
Mid-Atlantic to the Northeast as the cold front plows through
these areas. Cooler and drier air behind the front will spread
into the eastern U.S. on Saturday but high temperatures will
remain well into the 80s to lower 90s. Meanwhile, temperatures
into the upper 90s with humidity will be confined to the Southeast
on Saturday.
A second cold front, accompanied with a stronger surge of cool air
from Canada, will plunge into the mid-section of the country.
Temperatures behind this front will drop well down into the 40s
across the northern U.S. by Sunday morning. As the cold front
plunges southward, it will interact with a low pressure wave
located over the central Plains to trigger a round of strong to
severe thunderstorms together with heavy rainfall. The timing of
the inclement weather is forecast to begin during the day on
Saturday over the central Plains, expanding toward the southern
Plains, into the mid-Mississippi Valley and Midwest Saturday night
into Sunday morning.
Elsewhere, a round of generally light rainfall is expected tonight
into Saturday morning across Montana associated with the second
cold front. Some monsoonal type of showers are forecast to emerge
over the Four Corners and southern Rockies later on Saturday. The
Desert Southwest and the Central Valley of California will remain
hot into the weekend with highs into the 110s and 100s
respectively. Meanwhile, heat is forecast to build across the
Pacific Northwest with record high temperatures possibly reaching
into the 80s and lower 90s by Sunday afternoon.
