WeatherAnother Cold, Snowy Winter Ahead?
By Brian H. Tang
After last Saturday’s snow, you may have wondered whether a nasty winter lay ahead. The next day, the temperature rose 20 degrees, and your worries may have melted away with the wet, slushy snow. What does winter have in store for us?
While it is impossible to predict big events, such as the blizzard we had last January, this far in advance, there is some skill in forecasting whether the temperatures and the precipitation over the winter season will be above or below normal. Forecasters typically look at the amplitudes of big atmospheric and oceanic oscillations, such as El Ni o. When the amplitude is significantly positive or negative, it usually signals a higher probability of seeing an abnormal winter. However, this year, the oscillations are pretty much stuck at zero, which means there are equal chances of seeing a cold (wet), mild (dry), or normal winter.
While the winter forecast leaves something to be desired, you should forget about winter by enjoying the unusually pleasant weather this weekend. Today, Saturday, and the first half of Sunday all look more like a nice forecast from early October. Clouds will increase Sunday afternoon ahead of a front leading to a chance of rain late in the day. Monday will clear out behind the front, but it will be windy.
