Accumulations of 4-6 inches are expected for portions of Idaho and Montana. Further south across Colorado, Utah, and Wyoming, some areas may pick up 6-12 inches of snow with locally higher amounts in excess of 18 inches.

Thunderstorms for the Tennessee and Ohio Valleys on Saturday
An intensifying area of low pressure and associated cold front moving into the Tennessee and Ohio Valleys will lead to a potential for thunderstorms on Saturday. Though widespread cloud cover should limit instability somewhat, instability should be sufficient for the development of strong to severe thunderstorms capable of producing gusty winds. The timing for this severe risk will likely be during the afternoon hours.

Tropical Update
Disorganized showers and thunderstorms continue over the Caribbean Sea in association with an elongated area of low pressure. Strong upper level winds should limit the development of this system while it generally drifts northward during the next few days. Regardless of development, heavy rainfall is forecast over portions of Colombia, Hispaniola, and Puerto Rico through the weekend.

A Look Ahead
The cold front responsible for the thunderstorms across the Tennessee and Ohio Valleys on Saturday will continue to move eastward on Sunday, allowing for showers and thunderstorms along the East Coast. Some light snow may develop Sunday in the higher elevations of the Appalachians. Another system will move into the Pacific Northwest on Sunday bringing the potential for rain and high elevation snow. This activity will continue into Monday.
