Yayyy, congratulations Philly and Atlantic City... they will probably record their first measurable snow of the year finally. I think.. Just guessing by the radar and its snowing report at PHL. Have to see if it stuck
Hurricane Alex made landfall in the Azores. Not only rare to see a January landfalling hurricane, but rare to see a landfalling hurricane that far north (37°N) anytime of the year, let alone January.
Sea temperatures were a bit above normal, but not by a lot. Maybe this is the best explanation?
The Northeast Atlantic is a challenging location for hurricane development thanks in large part to its relatively cool water. Alex took on its tropical characteristics while over waters that were 20-22°C (68-72°F). Although these are up to 1°C above average for this time of year, they are far cooler than usually required for tropical cyclone development. However, upper-level temperatures near Alex were unusually cold for the latitude, which meant that instability--driven by the contrast between warm, moist lower levels and cold, drier upper levels--was higher than it would otherwise be. That instability allowed showers and thunderstorms to blossom and consolidate, strengthening the warm core that made Alex a hurricane as opposed to an extratropical or subtropical storm.
Strong El Niño + negative NAO = normal to somewhat below average winter temperatures
Strong El Niño + positive NAO = well above average winter temperatures
Sky looks like it's going to snow here too, only problem is is that it's 45 degrees too warm.
