Snow piled up in the Sierra Nevada this week, with 1 to 2 feet falling at Tahoe ski resorts Wednesday. The cold storm system notably differed from earlier storms this season. "This year has been a year of warm temperatures and rain when we should have had snow," said Andrew Schwartz, director of UC Berkeley's Central Sierra Snow Laboratory, located at Donner Pass. California's statewide snowpack is running below normal, due to the low amount of water stored in the snow that has fallen.

A high of 63 degrees and a low of 52. That’s San Francisco’s most common pair of daily temperatures over the past five decades. It only happened 189 times (about 1% of all days), but that’s far higher than any combination recorded in New York, a city that faces far more extremes. The Big Apple’s most common temperature combination, a high of 83 and a low of 67, occurred only 53 times over that period.

This year’s snowfall compared with 15-year averageData from Sept. 30 to March 14. Data not shown for places with a 15-year average of 3 inches or less. Though there is still a chance for some squalls, it’s safe to say Connecticut got half as much snow this year as what is considered normal. It’s the result, experts say, of natural cyclical weather changes, bolstered by global climate change.
