New Hampshire is poised for a classic early-summer flip—from cool, cloudy conditions to muggy midweek with pop-up storms, then a heat surge rivaling last year’s highs. Whether you’re hiking the Whites or heading to the seacoast, here’s what to expect.

🌥️ Early Week: Cool and Damp

Tuesday and Wednesday bring cooler temps in the mid-70s, with lingering clouds and occasional showers across much of the state. Expect patchy fog in the morning, especially near rivers and valleys, before brief attempts at sunshine warm things up by midday.

⛈️ Midweek Storm Watch

Thursday sees a sharp jump in heat and humidity, with highs near 90°F—fueling scattered thunderstorms in the afternoon. These storms may bring brief heavy downpours, gusty winds, hail, and even isolated tornadoes, especially over interior and higher elevations.

🌤️ Weekend: Heat Returns

After a breezy and slightly cooler Friday, temperatures will rise again. Saturday and Sunday hit the low to upper 80s, and Monday could tie or break early summer records with highs in the low 90s—the warmest day since last summer.
