...Severe thunderstorms are possible across portions of the Southern
Plains today, pushing eastward into the Lower Mississippi Valley Sunday...
...A wintry mix of snow, rain, and ice is expected to continue across the
Northeast today, changing to all snow and tapering off tonight...
...Snow will taper off throughout the day across the Western Great Basin,
Central and Southern Rockies, and portions of the Southwest...
The potent low pressure system that impacted much of the eastern U.S. over
the last few days is now moving off shore, with high pressure and drier
conditions expected to take hold east of the Mississippi River. The one
caveat will be the Northeast, where return flow will continue to combine
with cold air moving southward from Canada, resulting in a mix of rain,
snow, and ice across much of the region today. This will eventually change
to all snow as temperatures fall below freezing overnight, and then taper
off tonight and into the day Sunday as the low pressure system continues
to propagate eastward and away from the coast.
Another low pressure system will slowly traverse the Southern Plains over
the next couple of days. The position of this low will allow for a deep,
warm and moist southerly flow inland from the Gulf of Mexico ahead of the
associated cold front. This, in turn, will lead to rain across much of the
Southern And Central Plains, as well as embedded thunderstorms. For today,
the strongest storms will be along and just east of the cold front and dry
line which will set up across southwest Texas. The Storm Prediction Center
has highlighted much of South-Central Texas northward into Southern
Oklahoma as being in a slight risk for severe thunderstorms capable of
producing damaging winds and large hail. By tomorrow, the system will move
eastward and will merge with another warm front moving onshore from the
Gulf. This will increase the severe thunderstorm threat, and may lead to
isolated tornadic supercell development. As such, the Storm Prediction
Center has highlighted southeast Texas and southwest Louisiana in a
moderate risk for severe weather tomorrow. Surrounding areas will be in a
enhanced and slight risk for severe weather as well. Please refer to to
the Storm Prediction Center's website for more information.
Meanwhile, on the northwest side of the above mentioned area of low
pressure, snow is expected to slowly taper off today across the Western
Great Basin, Central and Southern Rockies, and portions of the Southwest.
Winter Weather Advisories and Winter Storm Warnings are in effect for
portions of this region where heaviest snow accumulations are expected.
Yet another low pressure system is poised to develop across Southeast
Canada during the day today. As it deepens and moves eastward over the
next couple of days, expect precipitation to develop and spread across a
good portion of the western U.S. by Monday. Precipitation will fall as a
rain or snow, or a mix of both.
