Today will feature noticeable increases in both temperature and humidity as southerly flow develops behind our retreating high. Look for the warmest temps in the west as areas farther east will get any sea breeze cooling effects boosted by the southerly synoptic component today. Highs will range from near 90 in SW NH to between 75 and 80 along the midcoast. Most places will top out in the mid to upper 80’s. Skies should be partly to mostly sunny region wide. An inversion aloft will act to put a lid on storm development today despite plenty of heat and humidity but an afternoon shower or sprinkle cannot be completely ruled out especially over the mountains. Nothing to cancel plans over but just something to be aware of.
Temps rise even more tomorrow and thunderstorms look to bring relief by Thursday or Friday.
