A study by Climate Central has found that a warming climate is increasing the potential for severe thunderstorms across Massachusetts, particularly during spring months. The study linked the increase to changes in "convective available potential energy," a measure of atmospheric instability that contributes to the development of thunderstorms with potential to produce tornadoes, damaging winds and hail. The most significant increase is occurring during the traditional severe weather season from April through September. The report suggests that warmer air holds more moisture, providing additional fuel for thunderstorms, which can result in stronger updrafts, heavier rainfall, and more damaging winds. The findings suggest that severe weather preparedness may need to adapt to a changing climate.
