URGENT UPDATE: New Hampshire is bracing for a significant surge in heat and humidity, with the National Weather Service issuing a heat advisory for eastern Hillsborough County and interior Rockingham County from 11 a.m. to 8 p.m. today, August 29, 2023. Residents should anticipate heat indices soaring above 95°F in interior southern regions, particularly in Nashua and Manchester.

The hottest day of the week is set to be tomorrow, Wednesday, as temperatures are expected to climb between the upper 80s and mid-90s. With humidity factored in, heat indices could reach the mid- to upper 90s during the afternoon hours. This extreme heat raises the risk of heat-related illnesses, especially for vulnerable populations.

Earlier this week, Concord and Lebanon recorded temperatures hitting 90°F on Monday, and if conditions persist, these areas could officially experience a heat wave by the end of the day on Wednesday.

As the week progresses, Thursday will see a slight dip in temperatures, with highs in the 80s, but humidity levels will remain high. The day will start with hazy sunshine, but a cold front is expected to arrive in the afternoon, bringing a new chance for showers and thunderstorms.

It appears that the weekend may bring some respite as the cold front moves offshore on Friday, providing a break from the oppressive heat and humidity.
