West
Snow will fall across the northern part of the region. The heaviest accumulations (2 to 6 inches) are forecast for eastern Montana and Wyoming. Light rain and rain showers are forecast for coastal areas from Washington to Central California. Expect winds gusting over 40 mph in the Northern and Central Rockies. Under an arctic air mass Montana and Wyoming will see high temperatures in the 10s and 20s.
Midwest
The snowstorm moving out of the West will spread precipitation across the Northern Plains, Upper Midwest and northern Great Lakes. Light to moderate snow (2-6 inches) will fall across the Dakotas, central and northern Minnesota, northern Wisconsin and far northwest Michigan. Rain showers will fall south of the snow across the Mississippi, Tennessee and Ohio valleys. Arctic air will produce high temperatures in the Dakotas and northern Minnesota in the 10s and lower 20s.
Northeast
High pressure centered off the Mid-Atlantic coast will keep most of the region dry. Rain will move into the region from the west and extend from West Virginia to Western New York with a few snow showers or flurries are possible in northern Maine. Windy conditions are expected from eastern Long Island through southeast Massachusetts. Temperatures will be 10 to 15 degrees warmer than yesterday.
South
Under high pressure most of the region will be dry. Precipitation will be limited to scattered showers along the Southeast coast, eastern Texas, Oklahoma and northwest Arkansas. Windy conditions are expected in Texas, Oklahoma, northern Arkansas and northwest Tennessee. The gusty dry winds (over 40 mph) will produce critical Fire Weather along the Texas/New Mexico Border.

Tropical Weather Outlook

Atlantic / Caribbean / Gulf
Area 1
A Large and elongated area of cloudiness and showers continues over the central Atlantic Ocean approximately 800 to 900 miles east and northeast of the Leeward Islands. This activity is associated with the interaction between a surface trough and tropical wave and an Upper-level low. Slow development is possible as this system drifts generally northward over the next couple of days and it has a low chance (20 percent) of becoming a subtropical or tropical cyclone during the next 48 hours.
Eastern Pacific
Area 1 (Invest 90L)
Shower activity associated with a low pressure system located about 450 miles south-southwest of the Gulf of Tehuantepec continues to become better organized. Environmental conditions appear conducive
For continued development and a tropical depression could form during the next day or two as the system moves west to west-northwestward at about 10 mph. This system has a high chance (60 percent) of becoming a tropical cyclone during the next 48 hours.
Western/Central Pacific
No tropical cyclone activity.
Earthquake Activity

No new activity (FEMA HQ)
