NH1 First Alert Weather: Heat, Humidity Headed to New Hampshire

We are quickly approaching the warmest time of the year, and some true summer warmth is in our forecast for the next few days.

The Fourth of July was a delightful day across the Granite State with sunshine and temperatures in the 80s. A few southern areas approached 90 degrees. A system tracking south of New Hampshire will spread clouds into the state for Tuesday morning. It may be a dull start near the Massachusetts border and along the seacoast with clouds and an onshore wind. It will also feel a bit more humid. Meantime, in central and northern New Hampshire, a mix of sun and clouds is expected throughout the day. As the sun increases in southern New Hampshire during the late morning and early afternoon, there may be just enough instability to pop a spot shower or thunderstorm, especially inland. These should not be widespread, but any showers or storms that develop during the afternoon may contain a brief downpour.

Temperatures on Tuesday will be in the middle to upper 80s on average. However, an onshore wind will keep seacoast towns cooler, with highs mainly in the 70s to near 80.

A big time warm-up arrives on Wednesday. High temperatures will reach the low to middle 90s throughout the region, with hazy sunshine and a moderate amount of humidity.

The most humid day of the week will be Thursday, ahead of an approaching front. Numerous showers and thunderstorms are possible Thursday afternoon. Temperatures should still manage to hit 90 degrees before these storms develop.

The forecast becomes unsettled and a bit uncertain for Friday and the weekend.

Friday will be a changeable day. It may turn quite cool in eastern and coastal areas with clouds and a cooler onshore wind. Temperatures as a result may only be in the 70s, coolest at the beaches. Inland areas may still manage the 80s to perhaps near 90 in western New Hampshire with a hazy mix of sun and clouds.

A disturbance will likely trigger showers and thunderstorms and cause cooler weather this weekend. At this time, it appears Saturday may be the wetter of the two weekend days, with scattered showers and storms. Sunday should be drier with partly sunny skies, but still the chance of a pop-up shower or thunderstorm. Be sure to check back for important updates on the weekend forecast throughout the week.
