Today will feature extremely hot and humid weather for part of the area as a ridge of high pressure builds in over the Eastern US, displacing the jet stream well to our north. New Hampshire will be in for the worst of the weather, while the Gulf of Maine’s cooling influence will spare most of Maine the worst. Look for sunny skies to drive temps well into the 80’s by late this morning. Across New Hampshire, light westerly winds will keep temps rising through the afternoon, with highs in the mid 90’s expected. Across Maine, look for a developing sea breeze to either keep temps in the high 80’s/low 90’s (inland) or result in temps falling into the upper 70’s/low 80’s (coast). Humidity will make the heat feel even worse, as dew points rising into the upper 60’s/low 70’s adds several degrees to today’s highs on the heat index. A late day shower or thunderstorm is possible in New Hampshire, but other than that, today will remain mostly dry.
