9. The Sudden Drop in Temperature

Another crucial natural warning indication that a tornado might be on approach is a rapid and obvious drop in temperature. Often fairly dramatic, this temperature change can happen quickly—sometimes in a matter of minutes. The dynamics of the intense thunderstorm generating the tornado define the phenomena. The storm takes cooler air from higher elevations as it gets stronger, which then falls and spreads out at ground level. With the warm, humid conditions usually preceding major storms, this chilly air outflow can produce a striking contrast. Sometimes the temperature drop is really notable, maybe ranging from 10 to 20 degrees Fahrenheit in a brief span. It is sometimes accompanied by an obvious rise in humidity, which could make the air feel thick and stifling. This mix of decreasing temperature and more moisture indicates that the storm is strengthening and that conditions are getting more favourable for tornado development. Though they can happen with every violent thunderstorm, not all temperature declines point to an approaching tornado. It should be taken extremely seriously, though, if this abrupt cooling is seen alongside other warning signals as darker sky, severe winds, or the sound of an oncoming roar. If you feel a fast and notable drop in temperature during severe weather, particularly if it is accompanied by an increase in wind speed or a change in wind direction, you should be aware and ready to find cover rapidly. Pay close attention to this temperature variation and other environmental signals to guarantee your safety; it may be one of the last cautions you get before a tornado strikes.
