Overview
- Frost and freeze alerts were in place Saturday morning from southeast Wisconsin to parts of Pennsylvania, with some valleys near or below freezing and gardeners urged to protect tender plants.
- The weekend stays cooler than normal for many areas, with highs often in the 50s and only spotty showers instead of a widespread washout.
- Higher elevations in northern New England pick up wet snow above roughly 2,000 to 2,500 feet, and forecasters urged hikers to avoid the White Mountains due to cold, wind and slick trails.
- A sharp warmup arrives Monday into Tuesday with widespread 60s and 70s and some spots reaching the upper 70s to low 80s.
- Thunderstorm chances return with the warm surge early week, with a low risk that a few storms turn strong in parts of the Plains and Midwest.
