The summer solstice is Monday at 6:34 PM EDT and the first day of summer will not disappoint! Temperatures will start off in the upper 50s and lower 60s early in the day, but afternoon highs will be near or just over 90 degrees in much of southern and central New Hampshire. A southerly wind will cool the coast just a tad; seacoast highs will be in the lower 80s. It will turn a bit humid for a time later in the day into the overnight.
A cold front will move into the state Monday night, spreading showers and perhaps a thunderstorm into western New Hampshire around or just after midnight. Scattered showers are possible throughout the rest of the state overnight into early Tuesday morning, but most of the activity will weaken as it moves through. The cold front will pass through the state during the morning, but with increasing sunshine, dry air and a westerly breeze, it will be another warm day on Tuesday. Highs will be in the middle to upper 80s in southern and central parts of the state, cooler to the north.
An upper-level disturbance will move into the region on Wednesday. This will cause more clouds and a few pop-up showers during the afternoon, especially in the northern half of the state. It will be cooler with highs near 80 south and in the 70s farther north.
Thursday will be the coolest day of the week with highs in the 70s statewide. A system will be tracking south of New Hampshire during the day, and it's possible a few clouds move into southern areas as a result. The rain should remain south of New Hampshire, tracking through the Mid-Atlantic.
There are signs that warmer air will make a comeback by next weekend with an upper-level ridge of high pressure setting up along the east coast. Temperatures on Friday may climb into the 80s (cooler along the coast with a seabreeze) and we may be nearing or exceeding 90 by the weekend!
Have a great week.
