...Record cold subfreezing temperatures this morning across much of the
South before a gradual warm up by this weekend...

...Wet weather pattern in place across the Pacific Northwest as several
rounds of moderate to locally heavy rain impact the region...

A large area of high pressure stretching from the Northeast to the
southern Plains will allow for a frigid morning across much of the central
and eastern United States. In fact, record cold is possible for several
locations from Louisiana to Maine in the form of daily record low
temperatures. Readings into 20s and 30s are likely to be widespread, with
localized teens possible in the typical cold valley locations just before
sunrise. The main impacts associated with these temperatures will be the
first freeze of the season for many locations. Sensitive plants could be
damaged or killed and exposed pipes could burst if proper precautions are
not taken. Freeze Warnings extend from eastern Texas to southern
Pennsylvania and New Jersey. Fortunately, for those who dislike the cold,
conditions should gradually warm with temperatures reaching closer to
average for this time of year by Saturday.

On the opposite side of the country, unsettled weather is set to remain
across the Pacific Northwest as a few Atmospheric Rivers move inland over
the region. The first batch of precipitation is ongoing this morning and
will spread moisture into the northern Rockies through tonight. Snow
levels will be rather high, with most snowfall accumulations located
across the Yellowstone region, northwest Montana, and the highest terrain
of the northern Cascades. Localized small stream and urban flooding is
possible across the Cascades and coastal ranges. By Friday night the next
round of moderate to locally heavy rain is expected to push inland and
create additional chances for localized flooding. Recent burn scars will
be most susceptible to flash flooding near northwest California and
southwest Oregon.

Mostly dry and tranquil conditions are forecast through Saturday across
the remainder of the CONUS. Warming temperatures will lead to widespread
highs into the 60s and 70s by Saturday from the Southwest and
central/southern Plains to the Mid-Atlantic, making for a picture-perfect
first weekend of November. Meanwhile, strong northeasterly winds behind a
cold front will make for blustery conditions and rough surf across much of
the Florida coastline
