Climate change increased temperature, reduced the amount of precipitation, decreased snowpack and increased the ability of air to soak humidity, helping to create arid conditions. As of 2021 the drought was the most severe in the last 500 years. [65] As of 30 June 2021 61% of continental USA were in drought conditions.
The radiative cycle in the stratosphere means that during winter the mean flow is westerly and during summer it is easterly. A final warming occurs on this transition, so that the polar vortex winds change direction for the warming and do not change back until the following winter.
The storm will be a prelude to what's expected to be a very cold, potentially stormy stretch of weather for much of the U.S. as the calendar turns to 2025. Times Square forecast is soggy
