New Hampshire's fourth heat wave this year will continue Wednesday, with highs in the 90s expected for many. The heat will be accompanied by storm chances.

A heat wave in New England is official when there are 3 or more consecutive days of 90-degree or hotter weather.

The best chance for much-needed rain comes Wednesday afternoon, when an approaching front could trigger scattered thunderstorms as highs reach the 90s. However, not everyone will see wet weather.
