...Dangerous heat to continue from California to South Texas into the
weekend...

...Rain and melting snow to raise flooding concerns across parts of the
Pacific Northwest and northern Rockies through the weekend...

...Storms producing damaging winds and heavy rain expected today from
Arkansas to the central Gulf Coast region...

From California to South Texas, Excessive Heat Warnings and Heat
Advisories remain in place across much of the region, as well-above normal
to record breaking temperatures are forecast to persist into the weekend. 
Daytime temperatures are expected to climb upwards of 10-20 degrees above
normal across much of California, the Great Basin, Southwest, and Texas,
reaching triple digits in many locations, with numerous records expected
to fall in the coming days.  With overnight lows forecast to offer little
relief, the potential for heat-related illnesses will remain high across
the region.  While temperatures will remain above normal from Southern
California to the Plains into early next week, a Pacific front will likely
bring both precipitation and much cooler temperatures into Northern
California by the latter half of the weekend.

A pair of Pacific fronts are expected to bring widespread precipitation to
the Pacific Northwest and northern Rockies on Friday and through the
weekend.  Periods of moderate to locally heavy rains, along with melting
snow, are expected to promote river and stream rises, prompting Flood
Watches for portions of Washington, northern Idaho, and western Montana.

Farther east, ongoing showers and storms across Kansas and Oklahoma will
continue to move south and east through the remainder of the morning, with
severe thunderstorms, producing damaging winds, expected across portions
of Arkansas into the lower Mississippi Valley and the central central Gulf
Coast region later this morning into the afternoon.  In addition to
damaging winds, heavy rains producing areas of localized flash flooding,
are also expected across parts of eastern Oklahoma and Arkansas into the
central Gulf Coast region today.

While the threat for severe weather appears to be more limited, showers
and storms and expected to spread into the eastern U.S. over the weekend,
potentially impacting outdoor plans.  Showers and storms are also forecast
to develop over the northern Plains and Upper Midwest on Saturday.  Some
of these storms may become strong to severe, with isolated large hail and
damaging winds possible.
