...Pacific storm system continues to bring lower elevation rain and
hazardous mountain snow to the northwestern U.S...
...Showers and thunderstorms continue ahead of a system moving through the
Southeast Sunday with some scattered flash flooding possible along the
central Gulf Coast...
...Coastal storm to generate periods of rain and thunderstorms in the
Southeast on Monday...
A storm system moving through the northwestern U.S. will continue to bring
lower elevation coastal/valley rain and hazardous high elevation snow
through Sunday. A cold front passage has brought cooler, drier air with
more moderate rainfall totals expected compared to the prior days fueled
by an Atmospheric River. Additional locally heavy snowfall can be expected
through the Cascades and ranges of the northern Great Basin/Rockies with
snow lingering longest into Monday for the northern Rockies. Some snow may
mix in for the higher mountain valleys of the northern Rockies but little
to no accumulation is expected. Gusty winds and high surf along the
Pacific coast will also remain possible. Initially light showers over the
northern High Plains Sunday will expand in coverage across the northern
Plains and Upper Midwest on Monday as the storm system continues east.
Some more moderate rainfall totals will be possible along with gusty
winds.
To the south, an upper-wave and accompanying surface frontal system will
move from the Southern Plains deeper into the Lower Mississippi Valley and
the Southeast Sunday supporting both continued organized thunderstorms as
well as additional development into the afternoon hours. While most of the
precipitation is expected to remain on the cooler side of the frontal
system limiting moisture and instability compared to the prior days,
locally heavy downpours and some isolated flash flooding will still be
possible. A narrow corridor ahead of the cold front along the central Gulf
Coast is expected to see a more moisture rich and unstable environment
supporting heavier downpours and the threat of scattered flash flooding,
with a Slight Risk of Excessive rainfall (level 2/4) now in place. Some
isolated severe weather including large hail, damaging winds, and a
tornado or two will also be possible. The upper-wave is expected to help
spawn an additional area of low pressure off the Southeast Atlantic coast
into Monday that will help to usher in additional moisture to fuel showers
and thunderstorms along the coast and inland through the southern
Appalachians. Some isolated flash flooding will be possible particularly
into the terrain of the southern Appalachians.
Elsewhere, thunderstorms are expected Sunday along the Atlantic coast of
Florida as a wavy frontal boundary lifts northward through the region.
Some spotty showers will be possible in New England. The rest of the
country should remain dry. Temperatures will be around or below Fall
averages across the Northeast/Mid-Atlantic as post-frontal high pressure
remains in place, with 40s, 50s, and a few 60s forecast. Below average
temperatures are also expected north of the track of the southern tier
upper-wave/cold front from the central Plains east through the Mid-South
and into the Southeast, with highs in the 50s and 60s. Some particularly
cooler and below average temperatures will come to the Carolinas/Georgia
on Monday with highs mainly in the 50s. Temperatures will continue to be
cooler and below average across the Pacific Northwest/northern California
into the northern Great Basin/Rockies following a cold frontal passage,
with highs mainly in the 40s and 50s. Warmer, above average conditions are
expected along the southern tier with 70s and 80s from Florida and the
Gulf Coast west through Texas and into the Desert Southwest. Some notably
above average, possibly daily record tying/breaking temperatures continue
in far south Texas with highs into the low to mid-90s. An amplified
upper-ridge continues to bring above average temperatures to the Four
Corners/central Rockies region northeastward into the northern
Plains/Upper Midwest, with 50s, 60s, and even some 70s expected.
