...An upper-level trough will keep temperatures cooler than normal in the
Northeast...
...Clouds and scattered thunderstorms will suppress daytime temperatures
in the South...
...Above average temperatures expected for the northern Great Basin and
northern Rockies...
The upper-level pattern will favor a trough lingering in the northeastern
U.S. as a progressive trough over the Pacific Northwest attempts to
intrude an amplified ridge axis along the High Plains. Temperatures over
the Northeast will be cooler than normal under the upper-level trough
along with widely scattered showers into early Saturday. Farther to the
west and southwest, the chance of thunderstorms will increase across the
northern mid-Atlantic, Ohio Valley and the Midwest toward the weekend as a
warm front approaches from the southwest.
The truly warm and humid air will continue to stay south of the front
across the Deep South and into the central and southern Plains. The Gulf
Coast will likely see the highest chance of thunderstorms as moisture
attempts to move up from the deep tropics. Scattered thunderstorms are
also likely over the southern High Plains where a lingering smaller-scale
upper-level trough provides the instability.
Meanwhile, the recent spell of hot weather in the Pacific Northwest will
move into the northern Plains by the weekend as an upper-level ridge
builds eastward ahead of a cold front. The Pacific Northwest will cool
down as an upper-level trough moves in behind the front. But temperatures
will begin the recover during the weekend. Meanwhile, scattered
thunderstorms can be expected to move across the northern and central
Plains on Saturday ahead of the advancing cold front.
