Relentless surges of cold air have been plunging into the Northeast and middle-Atlantic over the past couple of weeks, compliments of a huge trough in the jet stream. Such blasts of arctic air are not really that unusual for mid to late November, but they often are more fleeting in late-autumn. High temperatures as of this writing (Nov 21st) managed to reach the lower 40s, but strong winds and scattered flurries definitely brought a January-like feel to the air.
The general pattern may relax some next week, but still features the same basic Eastern trough configuration, which implies more below-normal temperatures. While some breaks with a day or two of warmer readings will also be seen, there’s a good chance that, overall, it will stay quite chilly into early December.
