Other than a pair of weather systems impacting the West Coast and scraping the Southeast Atlantic U.S., the Lower 48 states will be void of frigid air and an added bonus of plenty of late-November sunshine.

WeatherBug Meteorologist Addison Green has the latest in this exclusive WeatherBug National Outlook.

Today:

The most significant storm system will roll onto central British Columbia, flinging Pacific moisture as far inland as the Idaho Panhandle and Utah`s Wasatch Range. However, the steadier bursts of valley rain will pelt the Interstate 5 corridor between San Francisco and Seattle, while a few showers will develop as far south as Los Angeles late in the day. Thankfully, the rain will combat a slowly growing drought.

It will be a completely different story along the Cascades, Bitterroot Range and Sierra Nevada, where cold air will squeeze out accumulating snow for the higher passes. In general, several inches of heavy, wet snow will blanket the ground, making for slick travelling at times with gusty winds whipping about the flakes as they fly.

The only other minor weather inconvenience will be from the North Carolina beaches into southern Florida, where spotty showers and thunderstorms will have residents dawning umbrellas while heading to the store to prepare for next week`s Thanksgiving feast.

Not to be left out, the U.S. east of the Rockies will enjoy splendid temperatures and an equally bright blue sky for late-November.

Temperatures will be fairly mild with the coolest spots, 30s and 40s stretching from the Northwest into New England. While a few 70s and very low 80s will pop-up across Florida and the Desert Southwest, the rest of the U.S. will see seasonable 50s and 60s today.

Sunday:

Sunday will be almost a repeat performance of today, albeit a few changes will take place across the Atlantic Southeast and Mountain West.

The Rockies and points east will be dominated by another uneventful day, though temperatures will be on the comfortable side again.

While batches of rain and showers will remain stuck along the Interstate 5 corridor from San Francisco to Seattle, valley rain and mountain snow will spread deeper into the Wasatch and Bitterroot Ranges, cresting as far east as along the western slopes of the Colorado Rockies. Even so, accumulations will be much lighter at the higher mountain passes on Sunday.

The only significant weather change will be weak low pressure grazing the Carolinas, ushering in more widespread shower and thunderstorm activity all the way down to Florida`s Atlantic beaches. The rain is good news, helping to conquer a budding drought in the Southeast.

Just like today, temperatures will be uniform across the U.S. Temperatures will range from the 30s and 40s along the U.S. Northern Tier, to the 60s, 70s and a few lower 80s in Florida and the Southwest.
