NWS forecast

Warmer weather provides thaw, relief

In what UCLA climate scientist Daniel Swain has dubbed "weather whiplash," a dramatic warmup is expected across the continental U.S. next week. Forecasters say above-average temps will stretch across the country, with highs into the 60s or 70s in some places in the South.

The National Weather Service said there won't be additional replenishment of arctic air from Canada, so a "steady warmup" will start in the middle of the country by Sunday.

"With the high (pressure) retreating to the east, and (warm air advection) intensifying through the period, the warm air will eventually win out and cause a p-type transition to plain rain, likely as far north as Indiana and Ohio," the Weather Service said Sunday.

The warmth will also bring a chance for flooding due to rainfall and snowmelt, forecasters said.
