First Alert Weather: NH 'pick of the week' Monday, rain arrives Tuesday
After a cool start, Monday will be a gorgeous and pleasantly mild day. Lots of sunshine and a west-southwesterly breeze will allow temperatures to climb into the 50s to lower 60s from north to south across the state.
Clouds will increase Monday night, ahead of a developing coastal storm, forming off of the Mid-Atlantic. This will not become a particularly strong storm, but considering we have been in such a dry spell, it will bring a decent impact to part of the state. Tuesday will begin mostly cloudy and dry, and rain will develop from south to north from midday through the afternoon. Most places will see between 0.25" and 0.75" of rain, but some locally higher amounts over 1" cannot be ruled out in the heaviest downpours.
The most substantial impact from this system will be at the coast, where tides will already be running very high astronomically. Known as the 'king tides', these are the highest naturally occurring tides of the year. Even on a sunny day, low-lying and susceptible coastal areas flood during these very high tides. Monday's 10 a.m. high tide may bring some minor flooding and coastal inundation to the Backbay area of Hampton, and other susceptible coastal areas.
Adding an onshore wind to the equation, with this storm approaching from the south, and there will be more significant impacts at the seacoast in the form of coastal flooding and beach erosion on Tuesday. From about 10 a.m. to 1 p.m. Tuesday, vulnerable coastal areas will see rising water and inundation. The beaches are likely to have some rough surf, splashover, and erosion.
Wednesday, a northwesterly wind will develop. Low-lying areas may still flood, but erosion and surf should not be as intense as on Tuesday.
It'll be cloudy and damp to start Wednesday, but some sun should develop for the afternoon.
A warm-up is likely to end the week, with temperatures possibly approaching or exceeding 60 by Friday and Saturday!
The next front will arrive during next weekend. Currently, it looks like cooler air and showers will move in either Saturday night or Sunday.
