Lower 48...

...Slight Risk for severe weather in portions of Oregon and Idaho...

...Above normal temperatures and some fire weather risk in the West...

A wrapped-up storm system in the Mississippi Valley will continue its trek
to the northeast today, bringing a variety of weather hazards to the
Midwest, Tennessee Valley, and Southeast. Southerly flow out of the Gulf
of Mexico has transported warm and saturated air northward to the Great
Lakes region, and scattered showers with some storms will continue through
the morning hours. This afternoon, daytime heating will promote more
expansive showers and thunderstorms, some of which may be severe along the
I-75 corridor from Ohio southward to Georgia. In addition, heavy rain
falling over areas that have received appreciable rainfall recently may
lead to areas of flash flooding. Areas under the highest threat will be
around the Mobile, AL area into the Florida panhandle. By Friday, the
storm will continue to move through the Midwest into the Northeast,
carrying its cold front across the central/southern Appalachians. Showers
and thunderstorms will again expand in coverage during the afternoon hours
with a focus over the Mid-Atlantic region for both severe weather and
flash flooding.

In the West, a cold front will move into coastal Washington and Oregon
late tonight. Ahead of the system, mild temperatures and overspreading
moisture will contribute to showers and thunderstorms over eastern Oregon
into central Idaho, some of which may be severe. The Storm Prediction
Center has indicated a Slight Risk of storms with the main threat of
damaging wind and hail. Temperatures over much of the West will be well
above normal today, except for along the immediate coast. By Friday, the
front in the Northwest will being in cooler air to Washington and Oregon
eastward to northern Idaho, as the core of the heat moves into the central
Rockies and the western portion of the High Plains. Some areas may
approach record highs. South of this frontal system, warm temperatures,
low relative humidity values, and breezy winds will support a fire weather
risk over much of Nevada where some dry thunderstorms may also be
possible.
