Winter storm to track from West to East this week, U.S.

A winter storm is forecast to travel across the U.S. this week, bringing strong winds, snow, ice, and rain from the Rockies to the south-central U.S. and the East Coast, according to the National Weather Service (NWS) forecast on Monday, February 3, 2020.

"A strong low-pressure system over the Intermountain West Monday morning, along with a strong cold front, will generate widespread snow across parts of Idaho, Wyoming, Utah, and Colorado, where winter storm warnings and winter weather advisories are in effect," NWS wrote.

Through Monday night, much of the snow and strong winds from the storm will be in the West and the Front Range of the Rockies.

"The heaviest snow is expected to fall across the higher terrain of central Wyoming and north-central Colorado," said NWS, with accumulation up to 0.3 m (1 foot).

"There will also be strong winds across parts of eastern California, southern Nevada, and northern Arizona where high wind warnings are in effect."

In addition, return flow from the Gulf of Mexico ahead of the system will advect moisture towards the north, resulting in the development of scattered to numerous showers and some thunderstorms from eastern Texas to the Ohio Valley expanding into Tuesday.

From Tuesday to Friday, February 4 to 7, snow, ice, and rain are expected to impact areas from the Southern Plains to the Midwest and Northeast in multiple phases.

Furthermore, severe thunderstorms are likely in the warmer air ahead of the system in parts of the South.

A slight risk of severe thunderstorms is possible across parts of the Mississippi River valley on Tuesday.

The heaviest rain is forecast across parts of Tennessee and Kentucky, with up to 25.4 to 50.8 mm (1 to 2 inches) likely through early Wednesday, February 5.

"Elsewhere across the continental U.S., dry conditions can be expected from Florida to eastern Virginia, and also most of the Upper Midwest and northern Plains," NWS stated.
