This is referring to the kind of divide where one half of the U.S. could be blistering cold, while the other will be so mild. Warmer than normal weather and mild winter conditions typically develop over the southwestern United States, eastern United States, and eastern Canada. The UK is set to be hotter than Greece over the weekend as the countrycontinues to experience unusually warm temperatures this October. Its conceivable that such differences could influence precipitation in the Southwest U.S., but these differences are much smaller than the amplitude of the largest average La Nia tropical Pacific sea surface temperature anomalies, which approach 2 Therefore, it is difficult to see how such small sea surface temperature differences could have an influence that is comparable with the average La Nia influence. There appears to be a warming trend in our Octobers over the recent years, with many of them bringing milder than average spells.. You can see a strong snowfall anomaly over the Midwest and the Great Lakes, expanding over the northeastern United States. The increase this year has been associated with an extension of the jet stream into the Southwest, which we typically do not see during La Nina, and I do not see how the "triple-dip" classification would change that. Drier conditions also develop in the southeastern United States as La Nina produces a weaker subtropical jet stream and less moisture over the southern United States.
