It turns out we actually missed the record for warmest winter in recorded history. Chicago averaged 1.67°C from December 1st to February 29th, making it the 5th-warmest winter after 1881-82 (1.72°C), 1879-80 (1.78°C), 1931-32 (2.0°C) and 1877-78 (2.89°C). So it was only the warmest winter in 92 years, not the whole 153 years of data.
We did, however, have the warmest February on record, with an average temperature of 4.17°C. And it was unusually sunny: we had 75% of possible sunshine, while normal is 47%. Plus, the forecast for this weekend calls for a May-like 21°C at IDTWHQ.
Meanwhile, Lake Tahoe, Nev., could get almost 3 meters of snow this weekend as a major blizzard bumps up against the Sierra Nevada, with a 233 km/h wind gust reported at Palisades Tahoe Ski Base yesterday. That does not sound fun.
The Ecuadorean baby really screws with North American weather sometimes.
