A shower or two North Jersey, NYC and Eastern Pa ..... Fair Atlant... Showers and T-storms DFW
Unsettled weather and severe thunderstorm chances gradually expand
across parts of the central and southern Plains over the next couple of
days...
...Above average temperatures across much of the western half of the
country while cooler than normal weather prevails in eastern half...
The relatively benign weather pattern lately across the country is
expected to gradually become more active in the course of the next couple
of days as a low pressure system is forecast to develop and intensify over
the central Plains. The upper-level trough responsible for developing the
low pressure system is currently located over the subtropical eastern
Pacific, moving toward Baja California. This upper trough is forecast to
reach the southern Rockies on Thursday as the low pressure system
intensifies more rapidly over the central Plains later that day. Showers
and thunderstorms associated with the leading warm front across Oklahoma
Wednesday night is forecast to expand northward across the central Plains
during the day on Thursday and reach into the northern Plains by evening.
The thunderstorm activities will likely get stronger later in the
afternoon on Thursday over the central Plains ahead of a dry line. Winds
will also strengthen throughout the central Plains on Thursday as the low
pressure system intensifies.
In the meantime, a weak low pressure wave and a pair of cold fronts will
spark showers and embedded thunderstorms into tonight across the Great
Plains and parts of the Midwest. Some stronger thunderstorms may develop
over western Texas this evening associated with a cold front. By
later tonight, the Midwest should begin to clear out from the showers and
storms as they move into the Ohio Valley. Wednesday will see these storms
settling south across Oklahoma into the Tennessee Valley and into portions
of the Mid-Atlantic. Meanwhile, rapidly falling temperatures behind the
second cold front are expected to end the rain as a period of wet snow
across northern New England during the day on Wednesday. Meanwhile, the
trailing cold front entering the southern Plains will be the focus for
thunderstorms across the southern Plains on Wednesday, and they will
expand northward as the aforementioned low pressure system intensifies.
Elsewhere, unsettled weather is also in the forecast throughout parts of
the Great Basin and eventually the Pacific Northwest by Thursday as
initial upper ridging and well above average temperatures gradually erode.
Much of the rainfall is expected to be mostly beneficial outside of any
lightning potential with thunderstorms over the central Great Basin. Highs
throughout the southwest are anticipated to reach the 80s and 90s through
Wednesday, with 60s and 70s for much of the Intermountain West.
Cooler weather is in store for the Great Lakes and much of the eastern
U.S. behind the cold fronts. The cooler temperatures are forecast to
reach into the Carolinas on Thursday. Meanwhile, above average
temperatures will prevail across much of the western U.S. before the upper
trough brings cooler temperature as temperatures reach well up into the
80s to near 90 over the southern High Plains by Thursday afternoon.
