A surge of warmer air will bring summer-like temperatures to much of the Northeast through the end of the week, offering a welcome break from the cooler, wetter pattern that has dominated much of spring. Afternoon highs are expected to climb into the 80s across many locations, with some inland areas nearing 90 degrees by Friday. Plenty of sunshine and relatively comfortable humidity levels will make for ideal outdoor conditions.

The warm spell is expected to be short-lived, however, as a weather system moving in from the west begins to change conditions over the weekend. Clouds will increase on Saturday, followed by a growing chance of showers and thunderstorms. Rain is expected to become more widespread by Sunday, potentially affecting outdoor activities and travel plans across parts of the Northeast.
The Storm Prediction Center has issued a Slight risk for severe thunderstorms on Saturday for the Northeast. Scattered storms capable of producing large hail and damaging winds are possible for portions of the Great Lakes and Ohio Valley into the Northeast.

Behind the system, cooler air will return early next week, bringing temperatures back closer to seasonal averages. While some lingering showers may persist in a few areas, the return of rainfall will help replenish moisture in locations that have experienced drier conditions in recent weeks. The shift marks a return to a more typical early June weather pattern after a brief taste of summer heat.
