Weather Friday February 16 2024 Texas Coast rain Midwest snow moving northeast

Fast moving areas of low pressures to produce widespread accumulating
snows across the Central Plains, Mid Mississippi Valley, Ohio Valley,
Central Appalachians, Mid Atlantic, Northern New York and New England...
Heavy precipitation to move into Northern to Central California on
Saturday.
Heavy rains possible for South Texas...
Below average temperatures to spread southeast from the Northern
Plains.
Active Lake effect snows downwind of the Great Lakes Friday and
Saturday.
Two fast moving areas of low pressure pushing from west to east will be
producing widespread areas of accumulating snows across large portions of
the Lower 48. The lead area of low pressure will be moving eastward
tonight from the eastern Lakes region, across northern NY State and into
New England. This system will produce a brief period of snow, with
accumulations of several inches from northern New York State into portions
of central to northern New England. In the wake of this system, cold air
moving across the relatively warm and ice free Great Lakes will support
widespread lake effect snow showers downwind of the Great Lakes. Locally
heavy snowfall totals possible in the favored lake effect areas across the
Upper Peninsula of Michigan and across portions of north central to
northwest New York State, to the east of Lake Ontario.
This first fast moving area of low pressure will be followed by a second
moving quickly east northeast from the Southern Plains Friday, into the
Tennessee Valley Friday night and off the Mid-Atlantic coast early
Saturday. An area of snow will develop well to the north of the surface
low track, with accumulating snows possible from portions of the Central
Plains. east into the Mid Mississippi Valley, Ohio Valley, Central
Appalachians and Mid-Atlantic. The fast movement of this system will a
detriment to heavy totals, with generally 1 to 3 inches of accumulation
forecast across these areas, with isolated heavier totals possible.
Below average temperatures will be spreading south and southeastward from the
Northern Plains/Upper Mississippi Valley. This will produce a below
average temperature day on Friday across the Northern to Central Plains
and Upper Mississippi Valley, with these below average temperatures
spreading south into the Southern Plains and eastward into the Middle to
Lower Mississippi Valley, Ohio and Tennessee Valleys on Saturday. While
these colder than average temperatures are a departure from recent warmth
across this regions, the cold shot will be short lived with temperatures
warming from west to east late in the weekend and into next week.
The current stormy pattern across the eastern Pacific will be pressing
eastward on Friday into Saturday, with heavy precipitation pushing back
into Northern to Central California on Saturday. This precipitation is
the beginning of a wetter pattern for California, with additional heavy
precipitation likely for much of California for the beginning of next
week. The first round of heavy precipitation does have the potential to
produce isolated flash flooding across the central to northern California
coastal regions. The additional heavy rains slated for early next week
will also pose a flash flood threat, with this threat pushing farther to
the south into central to southern California.
An expanding area of rain also likely to develop Thursday night/early
Friday morning across South Texas, persisting into the day on Saturday.
This rainfall will also push east northeastward Friday into Saturday along
the northern Gulf coast and into North Florida. The heaviest totals
expected for South Texas where rainfall accumulations of 1 to 3 inches are
possible.
