Temperatures could be up to 35 degrees Fahrenheit above normal for this late February. The most abnormal warmth will settle over New York and New England, opening the door to spring-like conditions. The added boost to temperatures from Ohio to Georgia could mean high temperature records fall.

The boost in temperatures could also mean that the month ends in record or near-record warmth for parts of the Southeast. A cooler than normal January contributed to delaying spring in some locations. But next week’s heat will also jumpstart the spring bloom in some locations.

“Our six-day forecast is indicating that we’ll see a dramatic flip from the late spring onset that we’ve observed in the Southeastern states to up to two weeks early in Kentucky, Virginia, and West Virginia,” Erin Posthumus, the outreach coordinator with the National Phenology Network, told Earther.

She said that volunteers in the network—which tracks when the natural world responds to seasonal weather changes—will be looking out for buds on deciduous trees and some flowering plants. Climate change has ensured that spring now arrives earlier across the U.S.

That may be a blessing if you’re not a cold weather fan, but it also means migrating animals may arrive to find the food they normally survive on during stopovers is all gone. The early arrival of spring can also spell disaster for crops like apples or peaches if a late spring cold snap wipes out their flowers. That’s exactly what happened last year in the Southeast, which had a dismal peach crop following an extremely warm February and March cold spell.

The mild weather is a precursor of what’s to come. While we may see some cold weather again come March, the latest three-month outlook from the National Oceanic and Atmospheric Administration indicates increased odds for warm weather through May from the Southwest to the Northeast. Consider yourself warned about the potential for delightful spring weather.
