We are going to get a good lesson in atmospheric connectedness this week. Way back on Halloween, a tropical storm in the western Pacific grew strong enough to be named Typhoon Nuri. Nuri stayed out to sea and was mostly harmless, even if its winds briefly reached a sustained 180 mph at one point. As the storm moved northward last week Nuri lost its tropical characteristics and name but exploded into the most intense extratropical cyclone ever recorded in the North Pacific, bringing high winds and 50-foot waves to the Aleutians.

Here’s where the connectedness comes in. If all that air gets pushed northward, something’s got to give and head southward. The remnants of Nuri have managed to warp the jet stream to bring the first true cold outbreak of the season to the Midwest and eventually East Coast. Snow is expected and temperatures will be up to thirty degrees colder than normal across the High Plains.

Here in New York we’ve got a couple of sunny days with highs in the mid 60s before the cold front arrives Wednesday morning. Wednesday’s high should reach the lower 60s under mostly cloudy skies. The really cold air won’t be able to get over the Appalachians but Thursday will be lucky to reach 50 and highs through the weekend will stick to the mid 40s. Another storm early next week will probably bring us the first sub-freezing temperatures of the season.
