PHILADELPHIA (WPVI) — How much snow will we shovel off our sidewalks in the next few months? How cold or mild will it be?
To unravel the mystery of the approaching winter, we examine atmospheric signals that have now been established in the fall.
Let’s start by looking at recent trends. The pattern over the last few years is clear and consistent. Most months are above average. In recent decades, the winter season itself has warmed up faster than any other season. Five of the 10 warmest winters in Philadelphia have occurred since the turn of the century.
And indeed, last winter was the 12th warmest on record.
La Nina – it’s been in control for the past two years. This winter makes it a rare “triple dip La Nina”.
La Nina means cooler than normal sea temperatures in the eastern Pacific near the equator. This cooler water affects the weather in the US, especially during the months of December, January and February.
A “triple dip” means the US will experience La Niña conditions for the third straight year.
The key points for the coming winter are therefore a continued trend towards above-average temperatures. And with a storm stretch popular in our west, many events will be rain or snow turning to rain.
