This afternoon the atmosphere is about as quiet as a government office on a federal holiday.
Evidently that's about to change, with perhaps hailstones tonight and an old-fashioned nor'easter later in the week with gale-force winds, pounding rains and even wet snowflakes nearby.
The government's Storm Prediction Center (which is open today), has issued a severe-thunderstorm watch for all but extreme South Jersey, in effect until 10 p.m.
With the air quite unstable, as a front drapes across the region tonight, showers and possibly a hail-producing thunderstorm are likely to pop up between 8 p.m. and the early-morning hours. Then, the front sags to the our south and mutates into a storm highway. After a gentle midweek period, a full-blown nor'easter could affect the entire Northeast Thursday into Friday night.
