...Period of heavy rain and snow expected to continue across the West
before drier conditions arrive by Friday...
...Temperatures are expected to be well above average across much of the
central and eastern U.S. through Thursday...
...Freezing rain possible from portions of the southern plains to the
mid-Mississippi valley by Thursday night...
A series of Pacific storm systems will continue to impact the western U.S.
with heavy rain and snow through the next couple days. One frontal system
will move across the Great Basin toward the Rockies today, bringing
widespread snow to much of the interior western U.S. Snow will persist
across the central Rockies into Thursday as the front weakens overhead. A
second Pacific low pressure system will affect California by late
Wednesday, spreading another round of rain and mountain snow onshore. This
second system will bring another round of snow to much of the Great Basin
on Thursday, with scattered rain showers farther south over portions of
the Southwest. The potential for heavy rain and snow across the West will
persist as these two systems traverse the region. Heavy rain may lead to
flooding for some areas. By Thursday night into Friday, the chain of
Pacific storm systems will finally come to an end, and much of the West
Coast will have a chance to dry out. The second system will linger across
the southwest, however, keeping scattered rain and snow showers a
possibility into Friday.
High pressure at the mid and upper-levels will expand across the
southeastern quadrant of the Nation through Friday, which will bring a
period of unseasonably warm temperatures to areas from the southern plains
to the Great Lakes and Northeast. High temperatures today and Thursday
will be 15 to 30 degrees above average across these areas. The period of
warm weather will be ended by a strong cold front which will move south
across the central plains and Great Lakes on Thursday, and into the
Northeast and Mid-Atlantic Thursday night.
As colder air associated with the cold front moves into the southern
plains by Thursday night and Friday morning, moisture overrunning the
front is forecast to support the development of freezing rain. Freezing
rain is possible by Friday morning from portions of the southern plains to
the mid-Mississippi valley. Farther south, showers and thunderstorms are
possible along and ahead of the front, from much of Texas to the
Mid-Atlantic.
