...Tropical Storm Beta is forecast to slowly intensify as it moves toward
the Texas Coast...

...Frosts are likely from the Great Lakes into the Northeast and central
Appalachians....

...Above-normal temperatures to persist over the central and northern
Plains...

Over the next couple of days, Tropical Storm Beta is expected to slowly
intensify as it drifts northwest across the northern Gulf of Mexico
through the weekend and approaches the Texas Coastal Bend on Monday. 
Life-threatening storm surge and hurricane force winds are possible along
portions of the northwestern Gulf Coast, with tropical storm conditions
expected by late in the weekend.  Storm Surge and Hurricane watches and
Tropical Storm warnings are in effect.  Residents in these areas should
ensure that their hurricane plan is in place and follow advice given by
local officials.  Due to its slow motion, Beta has the potential to
produce long-duration, heavy rains -- resulting in widespread significant
flooding along the western Gulf Coast.

Elsewhere, dry conditions are expected across much of the remainder of the
U.S. into early next week.  Strong high pressure will continue to support
dry conditions and below-normal temperatures across much of the eastern
U.S. through the remainder of the weekend.  Frost and freeze warnings are
in effect for Saturday night and Sunday morning from portions of the Great
Lakes and Northeast to the central Appalachians. From southern New England
to the Southeast, daytime temperatures along the East Coast on Sunday are
expected to remain several degrees below normal in most places.

A frontal system is expected to bring beneficial moisture and cooler
temperatures as it moves across the northern Rockies into the Plains on
Saturday.  However, gusty winds and dry conditions ahead of the system
have resulted in another day of Red Flag warnings for portions of the High
Plains and Great Basin.  This system is not expected to produce a lot of
precipitation as it moves across the northern Plains and Upper Midwest on
Sunday.  Above normal temperatures are forecast to continue across the
northern and central Plains on Sunday, before extending into the Upper
Midwest on Monday.
