A powerful storm of Pacific origin is brewing over the Western US Thursday. The storm will produce a narrow but long swath of heavy snow and ice stretching from the southern Plains to the Great Lakes. This same storm system is also expected to produce a severe weather outbreak over the South-Central US. The storm will be so dynamic that parts of the Southern Plains will be threatened by both severe weather and winter weather. Spring-like warmth and copious quantities of moisture are expected to pour from the Gulf of Mexico into the Southern and Central US Friday as low pressure intensifies over the Arklatex. Arctic cold over the Northern Plains will act like a wall against the oncoming subtropical air mass. Where the warmth encounters no hurdles, torrential downpours from thunderstorms will produce areas of flash flooding and river flooding. In the South-Central US, these storms will become severe,…

A storm system more reminiscent of spring than the dead of winter will besiege the South with severe thunderstorms and torrential flooding rain Friday and Saturday. The Arklatex and the Gulf Coast are expected to face the brunt of the severe weather, where violent straight-line winds, large hail, and dozens of tornadoes are expected. The upper-air energy responsible for the violent weather originated in the Pacific Ocean and only approached the northern California coast Thursday morning with scattered rain and snow showers. That nuisance area of precipitation will undergo a rapid transformation as the supporting area of upper-level energy intensifies over California and the Desert Southwest through Thursday night. The precipitation will largely dissipate but the supporting upper-level system will nonetheless deepen into a highly amplified trough. New area of low pressure will develop over Texas early Friday with the approach of this vigorous Pacific system.The rain will begin Thursday…

Blinding, wind-swept downpours will plague the Southeast this weekend as a storm develops in the Gulf of Mexico and slowly treks toward the Atlantic Ocean. The onset of the storm in Florida and parts of the Deep South this weekend will coincide with the departure of millions of Americans traveling to holiday destinations. The intensifying storm is expected to bring gusty winds up to 50 mph and rainfall totals as high as 8” in the hardest-hit areas. The storm will organize much like Nor’Easters common along the Northeast Coast this time of year. A robust jet stream is supplying a deep pool of relatively cold air toward the warm Gulf of Mexico. The Gulf’s surface temperatures, while warm, are too cool for the development of a tropical cyclone. Bands of heavy precipitation will develop ahead of a cold front and compose a shield of precipitation north of a warm front as…
