Wall Street's "Black Tuesday", which presaged the Great Depression, was partly cloudy and chilly with a high/low of 49°/37°, about ten degrees below average.
One day after a high of 77°, today's reached 78°, a record for the date (and 19 degrees above average). This was the mildest reading since Sept. 16.
A heavy, all-day rain amounted to 3.67", a record for the date. Up until today just 0.03" had fallen in October (and it fell twenty-seven days earlier).
Today and the past three days had unseasonably warm high temperatures that were very similar: 77°-76°-77°-76° (today).
Although it was just 0.01", the rain that fell today was the first on this date since 1984 (when just 0.02" fell).
Until yesterday it had been a dry month, with just 1.26" of rainfall measured. Then 3.62" fell in the past three days, including 1.63" that fell today.
An intense nor'easter lashed the area with high winds and outrageously early snowfall. The 2.9" of heavy, wet snow that was measured in Central Park was the most ever to fall in October (5.2" fell in Newark and over a foot buried northern NJ, parts of the Hudson valley, Connecticut, western Massachusetts and New Hampshire). Since the temperature never fell below freezing, there was mostly just slushy accumulation on City streets. However, the day's low of 33°, which occurred in the early afternoon, was the coldest reading in October since 1988. Total liquid precipitation from the storm was two inches. Remarkably, the next measurable snow wouldn't be for another twelve weeks (when 4.3" fell on Jan. 21, 2012).
Unbelievably, an even more devastating storm than last year's nor'easter - hurricane/nor'easter Sandy - struck between noon and midnight. And it more than lived up to its hype. Although rain wasn't the issue (less than an inch fell), its 60-80 mph wind gusts and record storm surge wreaked havoc on New York's transportation system and power grid. Not only did the storm surge strike at high tide, but also during a full moon, resulting in flooding never before experienced in Manhattan.
On the five-year anniversary of superstorm Sandy, an intense nor'easter lashed the area with gusty winds and an all-day rain that amounted to 3.03". This was more rain than fell in the past 60 days, and the biggest rainstorm of the year, passing the rainstorm of 5/2 by 0.01".
The remnants of hurricane Zeta (which struck the Gulf Coast last night) combined with the energy from a winter storm that struck the southern Rockies and Plains earlier in the week, resulting in rainy and raw conditions in the Mid-Atlantic states. Rain began here around 7 AM and continued until mid-day on the 30th. 1.53" fell today, 0.64" the next morning. The rain fell heaviest from 10 AM until 3 PM today, with nearly an inch measured. After the rain became lighter gusty winds of 25-30 mph moved in.
