The Weather Man Podcast, I talk about weather!

Rainy, stormy weather continues along the East Coast through Thursday,
lingering in New England Friday...
...Unsettled weather for the West, with a late season Atmospheric River
impacting California Friday...
...Warming trend begins over Central U.S. on Thursday...
Showers and storms will continue along the East Coast Thursday as a pair
of slow moving cold fronts pass through the region. Locally heavy rainfall
is expected over portions of eastern North Carolina and southeastern
Virginia where a wave of low pressure will help to enhance convergence and
storm converge/intensity. A Slight Risk of Excessive Rainfall (level 2/4)
will continue through the overnight hours Wednesday into the day Thursday
with some scattered instances of flash flooding possible. Storms will
begin to clear the coast from south to north through the day Thursday as
the lead front pushes into the Atlantic, lingering longest in New England.
Here, an intensifying area of low pressure off the coast will keep moist
onshore flow into the region through Friday. Some of the rain may be heavy
at times Thursday along the coast, leading to some areal flood concerns
when combined with snowmelt. Precipitation is expected to change over to
snow for interior locations of the region by Friday night, with some light
to moderate accumulating snowfall possible. Winds will also become a bit
gusty Friday as the low deepens offshore.
Areas of lower elevation coastal/valley rain and higher elevation/mountain
snow will continue across the West Thursday and Friday, generally
spreading further southward and eastward as a frontal system moves through
the region. Some locally heavier snow totals will be possible for regional
mountain ranges from the Pacific Northwest southward into northern/central
California, as well as for the eastern Great Basin into the
northern/central Rockies. The greatest impacts are expected in the
northern Sierra through Thursday morning where a Winter Storm Warning is
in place. A more intense system over the Pacific will approach California
on Friday, bringing an enhanced onshore flow of anomalously high
moisture/Atmospheric River directed at portions of central and southern
California. Rainfall will pick up Friday into Friday night/Saturday
morning along upslope portions of the Transverse Ranges, where a Slight
Risk of Excessive Rainfall is in place, as a few inches of rainfall may
lead to flooding, especially for terrain sensitive areas. This threat will
continue into the weekend beyond the current forecast period.
Elsewhere, some snow showers will linger Thursday for portions of the
Upper Midwest/Great Lakes, particularly close to the Canadian border, as a
low pressure system departs the region into Canada. A shortwave following
this system will bring some additional light rain/snow showers to the
Northern Plains into the Upper Midwest on Friday. Temperature-wise, some
chilly morning lows dropping into the low to mid-30s are forecast Thursday
across portions of the Mid-South into the Tennessee Valley following a
cold front passage, with Frost/Freeze-related advisories and warnings in
place for newly greening sensitive vegetation. Increasing upper-level
ridging following the system over the East Coast and ahead of troughing
over the West will bring warmer, above average temperatures broadly across
portions of the High Plains Thursday, and into the Plains/Mississippi
Valley/Midwest on Friday. Highs will remain either around or below average
along the East Coast and across most of the West with the upper-level
troughing in place.
