Midwest

Ample moisture, relatively warm temperatures, and a stagnant wind field will facilitate the formation of a large area of fog across the Midwest. From Minnesota to the Red River Valley conditions will worsen overnight Monday into Tuesday morning as visibilities are drastically reduced and travel conditions worsen. The fog will linger through the early part of the day Tuesday, but will burn off substantially by the afternoon hours. Again, temperatures will remain relatively warm for the Northern Plains with highs some 15 to 20 degrees above daily averages.

 

South

The southern branch of the jet stream will continue pumping out showers and thunderstorms throughout the night Monday. Tuesday the story changes little as subtropical moisture flows over the region. Rain, showers and storms will continue from the Gulf Coast to south of Interstate 40 on Tuesday. The heaviest of the rain and storms, however, will remain along the I-10 corridor from San Antonio to Mobile Bay. On the back end of the precip area, a weak upper-level disturbance will roll down the southern Rockies sparking snow from New Mexico to western Texas. Winter storm warnings are in effect for southeast New Mexico and most of west Texas where the greatest snowfall accumulations could be in the range of six to ten inches. Temperatures across the region will be cooled by the falling precipitation. Highs Tuesday will be 10 to 20 degrees colder than average.

 

West

Snow is in store from the central Rockies to west Texas Tuesday as a combination of a weak upper-level system, intruding cold air and Pacific moisture convene on the area. Lighter snow showers are forecasted for the central and southern Rockies. Locally heavier snow is expected for southeast New Mexico into west Texas. West of the Rockies, towards the coast, all remains quiet. Persistent onshore flow will bring the occasional light shower to the immediate Pacific Northwest coast. Temperatures outside of the areas affected by precipitation will be on par for early February.

 

Northeast

High pressure is in total control of the Northeast. Tuesday’s highlights for the region include a total lack of precipitation and seasonable temperatures. Tuesday morning’s lows will range from subzero across northern Maine to the teens in the big cities. By the afternoon, temps will warm across the board into the 20s and 30s, right on par for the first day of February. Quiet conditions and near-average temperatures will continue Wednesday.
