...Severe thunderstorm potential today for the Mid-Atlantic Seaboard...
...Heavy snow likely for the Northern/Central Rockies, Great Basin and
Wasatchs...
...A wintry mix of rain, snow, and ice is expected for the Northeast today
and tomorrow...
...Severe thunderstorms are possible across portions of Kansas, Oklahoma,
and Texas tonight and tomorrow...
A strong area of low pressure and associated surface frontal features will
continue their eastward progression across the Mid Atlantic and Southeast
today. The cold front is expected to reach the Atlantic Seaboard by this
evening. Until then, expect continued precipitation along and ahead of the
cold front, affecting much of the East Coast. Rainfall will be heavy at
times, and thunderstorms may also occur once again. The Storm Prediction
Center has outlined portions of Southeast Virginia and the Eastern
Carolinas in a slight risk for severe weather today, with the main threats
being damaging winds and large hail. Please refer to the SPC's Convective
Outlooks for more information.
Meanwhile, on the northeast side of this system, moisture flux from the
Atlantic Ocean inland will combine with a colder airmass pushing southward
from eastern Canada. This will result in a mixture of rain, snow, and ice
across much of the Northeast today and tonight, before changing over to
mainly snow Saturday, then tapering off by Sunday. Winter Weather
Advisories and Winter Storm Warnings are in effect for a large portion of
the northeast.
Attention then shifts to the western U.S., where an elongated cold front
is currently moving eastward along the western fringe of the Rockies.
Expect this system to split as it moves over and east of the Rockies
during the day today, with one section moving into the north-central U.S.,
and another into the south-central U.S. Rain and higher elevation snow
will remain in place across much of the Rockies and western portions of
the Northern and Central Plains today through Saturday. Winter Weather
Advisories and Winter Storm Warnings are in effect for portions of the
Northern and Central Rockies for snow potential.
The redeveloped south-central U.S. low pressure system will slowly track
eastward across the Southern Plains over the next couple of days. By
tonight, the pull of warm and unstable air from the Gulf of Mexico will
interact with the associated cold front to produce yet another round of
thunderstorms across this region, persisting through the weekend. The
Storm Prediction Center has outlined a portion of the Texas and Oklahoma
Panhandles, northward into Western and Central Kansas, as being in a
slight risk for severe thunderstorms, mainly for tonight. West-Central
Texas will be under a slight risk during the day Saturday into Saturday
night. The threat is expected to increase along the Gulf Coast by Sunday
as the system pushes eastward towards this region.
