NH1 First Alert Weather: Major weather changes for NH this weekend
Friday was as hot and humid as it gets in the Granite State, with Concord reaching a high temperature of 99, tying the day's record set in 1944.
Major changes are coming for the weekend, however.
Overnight, a "backdoor" cold front moved into the Granite State. This front is dividing Friday's intense heat and a cooler, maritime air mass.
As a result, Saturday will be cloudy and much cooler. It will be coolest near the seacoast, with very little sunshine and temperatures struggling to rise into the 70s. Quite a range in temperature is expected across the state. In western areas, hazy sunshine will boost temperatures well into the 80s from Keene to Lebanon. In between, temperatures will generally be in the middle to upper 70s for highs.
Downpours and thunderstorms are expected in parts of the area during the afternoon. In such a humid airmass, any of these storms can contain very heavy rain, frequent lightning and gusty winds. With such cool, cloudy weather near the coast, very little rain is expected there. Farther inland and to the west, chances for storms are much higher during the afternoon. Any breaks of sunshine will allow these storms to strengthen and become strong.
Heat and humidity surges back into the state on Sunday, with high temperatures in the upper 80s and low 90s. Any early clouds should give way to a mix of hazy sunshine and clouds. Some pop-up, scattered thunderstorms will occur during the afternoon with the heating of the day. Not all areas will see the rain. Sunday will by far be the brighter of the two weekend days.
In general, a muggy pattern continues into next week, though the humidity may subside some on Monday. Highs Monday and Tuesday will be in the mid to upper 80s for most. The next threat of thunderstorms will come late Tuesday or Wednesday. There could be some heavy rain in parts of the state on Wednesday, with a drying trend into the end of the week.
Have a great weekend!
