Two weather features were expected to continue bringing wet weather to the U.S. on Wednesday.

One strong low pressure system was forecast to persistently advect northeast over the Southeastern states and into the Tennessee Valley and Mid-Atlantic states. This could continue to pull abundant moisture off the Gulf of Mexico and spread scattered showers well into Kentucky and the Virginias.

Periods of heavy downpours were expected to track through Florida, Georgia, and the Carolinas. Strong winds were forecast to accompany this system with gusts of up to 60 mph in some areas. The South was expected to see cool conditions with highs in the 50s.

The system also could advect minor moisture into New England and Northeastern states. Overcast skies with a few sprinkles were expected with highs remaining in the 40s.

In the North, a strong low pressure system was expected to dip into the Upper Midwest from central Canada and pull a cold front over the region. The system, associated with bitterly cold temperatures, could keep high temperatures in the single digits in the Northern Plains and western Great Lakes.

The system also was expected to continue to bring light and scattered flurries to Minnesota that could move into northern Wisconsin by evening.

Out West, high pressure was forecast to hover over the West Coast and bring another warm, dry day. Temperatures in California were expected to remain in the 60s and 70s, while the Pacific Northwest could see highs near 50.

On Tuesday, temperatures in the Lower 48 states ranged from a low of 1 degrees at Alamosa, Colo. to a high of 87 degrees at Boca Raton, Fla.
