...Drier conditions expected for the West Coast states by Friday, while
the Southwest remains unsettled...
...Accumulating freezing rain possible on Friday from the southern plains
to the mid-Mississippi valley...
...Above average temperatures expected today from Texas to the Northeast...
The pattern will begin to change along the West Coast over the next couple
days as the string of Pacific storm systems comes to and end and drier
conditions prevail by Friday. Rain and mountain snow will continue across
California for one more day today as the last low pressure system moves
inland. Heavy snow will still be possible in the Sierras and the San
Bernardinos into tonight, with locally heavy rain possible at the lower
elevations. On Friday, the low pressure system will move into the interior
Southwest, allowing much of the West Coast to dry out. A few lingering
snow showers are possible in the Sierras Friday, but these should
gradually wind down by late in the day. Across the interior Southwest,
rain and snow showers will persist through Saturday as the low pressure
system will be slow clear the area.
Farther east, a cold front will usher a much colder air mass southward
across the plains and mid/upper Mississippi valley today. The front is
forecast to become stationary on Friday from the southern plains to the
Tennessee valley. Showers and thunderstorms are expected along and ahead
of the front from Texas to the Northeast. By Friday, moisture is expected
to begin flowing farther north across the frontal boundary into the
shallow cold air mass north of the front. This will allow for freezing
rain to develop from portions of Oklahoma and northern Texas to the
mid-Mississippi valley. Portions of this area could see significant ice
accumulations through Friday night, with the potential for freezing rain
also expanding east into portions of the Ohio valley and Mid-Atlantic by
Saturday morning.
Meanwhile, ahead of the cold front, unseasonably warm temperatures will
prevail. High temperatures today are expected to be 15 to 30 degrees above
average from Texas and the Ohio valley to the East Coast. Highs may reach
into the 70s for some areas from Texas to the Southeast. On Friday,
temperatures will once again be well above average, although over a
smaller area as the cold front makes some forward progress. High
temperatures on Friday are expected to be 10 to 20 degrees above average
once again from southern Texas to the Southeast and southern Mid-Atlantic
region.
