Yesterday's forecast was calling for severe weather to sweep across the region today, but mother nature had other ideas. This begs the question, what happened? The answer as to why we didn't see any severe storms run rampant across the Twin Tiers is cloud cover.The persistent cloud cover during the morning hours lead to a not so severe afternoon, here's why.

One of the ingredients for severe storms is instability and this is defined as air rising and accelerating away from its original position. In order to have instability you need heat and humidity, and this is where the persistent cloud cover comes in. Sunlight helps to heat the ground and cause the atmosphere to become unstable over time. Unlike the past couple of severe weather events across the region over the past week we had cloud cover during the morning. This cloud cover did not allow the ground to heat up as quickly and reflected most of the energy needed for thunderstorm growth back out to space.
