US Hazards

Snow Continuing for the Northern Rockies and High Plains on Monday
A weak area of low pressure will continue to promote light to moderate snowfall from the Northern Rockies into the High Plains region through the morning hours on Tuesday. Widespread accumulations of 2-4 inches are expected with locally heavier amounts in excess of 6 inches in the higher elevations. Winds may gust more than 30 mph, allowing for low visibilities.

Snow Accumulation for Monday

Thunderstorms Monday across the Southeast
As an area of low pressure and the associated fronts slowly move eastward on Monday, severe thunderstorms may develop from eastern Georgia through the coastal Carolinas. Although ongoing showers and thunderstorms, along with cloud cover, will limit instability, a few strong to severe thunderstorms may develop. Large hail, damaging winds, and tornadoes will all be potential hazards with these storms. As these storms move eastward into the night time hours, damaging winds and isolated tornadoes will become the primary concerns.

Thunderstorm Risk for Monday

Excessive Rainfall for the Carolinas on Monday
An area of low pressure slowly moving eastward across the Southeast will continue to produce showers and thunderstorms across the region. Rainfall totals of 1-2 inches are expected with localized amounts in excess of 3 inches. The most significant risks for flooding will come from repeated rounds of thunderstorms, as well as severe thunderstorms, that may cause heavy downpours and flash flooding.
