New Hampshire Weather Outlook: Cool Start, Sunny Mid‑Week, Showers Thursday

It’s going to be a bit of a cold snap to kick off the week in New Hampshire, especially up in Coos County where a frost advisory hangs over the area until 8 a.m. Tuesday. Expect lows in the 30s before sunrise, so anyone with tender plants should consider covering them or moving them indoors – a light coating of frost can do more damage than you’d think.

Once the sun rises, the sky clears out for most of the state. Tuesday will feel dry and quite pleasant, with plenty of sunshine and highs hovering around the low 70s. It’s the kind of day that feels like a gentle reminder that winter is still lingering, but summer is just around the corner.

Wednesday nudges the mercury a touch higher. Southern portions of the state may see temperatures creep toward 80 °F, while the rest of New Hampshire stays comfortably in the mid‑70s. It’s a nice warm‑up after the morning frost, and you’ll probably want to spend more time outdoors.

Then, on Thursday, the mood shifts. Moisture starts moving in, and the forecast shows a decent chance of showers across the region. The rain brings a cooling trend that will linger through the weekend, so keep an umbrella handy if you’re heading out.

All told, the week starts cool and clear, warms up nicely by mid‑week, and finishes with a wetter, cooler finish. Stay tuned for any updates, especially if you’re in the frost‑affected zones.
