Nor’easter dumps up to two feet of snow, five inches of rain


Snowfall totals from April 23 Nor’easter (NOAA)
The biggest late April Nor’easter since 1928 is winding down after producing a large swath of driving rains near the mid-Atlantic and Northeast coast and heavy, wet snow in the interior. The prolific precipitation producer has drifted into Canada and all winter storm warnings and advisories have been cancelled. Some light snow and rain linger in a few locations.

Laurel Summit in Somerset county, Pa., at an elevation of 2,700 feet, hit the snow jackpot with this storm recording an astonishing 23.2” of snow. Not far away, at Seven Springs ski resort, a foot fell and, the resort is open for skiing today. It is the latest on record the resort has been open, 10 days later than 1996, the previous record holder.

Snowfall with this storm was highly elevation dependent with the heaviest amounts falling in the mountains of west central Pennsylvania and western New York.

Here are some of other leading snowfall totals by state: Newfield, NY 10”, Sylvania, Pa. 11.0”, Frostburg, Md. 6”(2 miles NNW), Aurora, WV 5”.

Significantly less snow fell at lower elevations. For example, Buffalo, NY received 0.8” and Rochester 2.6”. Merely a trace of snow fell at State College, Pa. and no snow was reported in Pittsburgh.


Rainfall totals from April 23 Nor’easter (NOAA)
Rainfall amounts were highest from the coast of central New Jersey through southern New England where 2-5” were common. Newark, NJ received 3.03”, Central Park, NY 2.89”, Providence, RI 3.4”, Foxboro, MA 3.5”, Portland, ME 4.2”. New Boston, NH recorded the largest total, a drenching 5.04”.

CapitalClimate notes about two dozen daily rainfall records were set Sunday and Monday.

On WJLA’s weather blog, Bob Ryan calculated the storm dumped the equivalent of 7.5 trillion gallons of water on the East:

So how much is 7.5 trillion gallons? Well (check my math again) it’s enough to roughly give every man, woman and child on earth 8 big glasses of fresh water every day . . . for about 4 YEARS!!

Despite the tens of thousands of power outages resulting from the weight of the snow in the interior, the storm was highly beneficial for the coastal mid-Atlantic and Northeast, a region in the early stages of drought.

The U.S. Drought Monitor as of last Thursday showed moderate to severe drought from Baltimore, Md. to Portland, ME. The rains from this storm cut annual rainfall deficits from 20-40 percent - probably enough to shift many of those locations in severe drought to moderate drought and areas in moderate drought to the abnormally dry designation. The next Drought Monitor will be issued this Thursday.
