...Severe thunderstorms and flash flooding possible from portions of the
southern plains to the Ohio valley...
...Heavy snow possible for portions of the Rockies and the High Plains...
...Above average temperatures expected for much of the eastern U.S...
An active weather pattern is expected to persist from much of the central
U.S. into the Ohio valley through the next few days, with hazards ranging
from severe thunderstorms and flash flooding to heavy snow. A frontal
boundary is forecast to linger from the southern plains to the
mid-Mississippi and Ohio valleys into the weekend as multiple waves of low
pressure traverse the boundary. A deepening upper-level low moving from
the Rockies into the southern plains will keep deep southerly flow in
place across the central U.S., transporting abundant moisture northward
for precipitation. Scattered to numerous showers and thunderstorms are
expected today through Sunday for much of the southern and central plains,
the Mississippi valley, and the Ohio valley. Severe thunderstorms and
flash flooding are both possible from portions of the southern plains to
the Ohio valley today and Saturday. Please refer to products issued by the
Storm Prediction Center for further details on the severe weather threat.
Cold air on the northwestern side of the system will produce a mix of rain
and snow from the Rockies into portions of the northern and central High
Plains today. Heavy snow is possible for some areas in the central and
northern Rockies as well as the adjacent High Plains. As colder air
spreads south on Saturday, rain is expected to change to snow across the
southern Rockies as well as portions of the southern High Plains, with
heavy snow once again possible for some areas.
Across the eastern U.S., high pressure at the mid and upper levels of the
atmosphere will support well above average temperatures. High temperatures
today and Saturday are expected to be 10 to 20 degrees above average for
some areas. A cold front may produce some scattered showers and
thunderstorms across the Mid-Atlantic region Saturday afternoon into
Sunday.
