00:00:00.120 --> 00:00:04.350
On April 1, 2017, a Nor'easter hit New England, covering the region with snow.

00:00:04.370 --> 00:00:08.400
On April 1, 2017, a Nor'easter hit New England, covering the region with snow.

3
00:00:08.420 --> 00:00:12.450
A Nor'easter forms when warm, moist air traveling north with the Gulf Stream

4
00:00:12.470 --> 00:00:16.580
collides with cold air moving down from Canada, resulting in snow and rain.

5
00:00:16.600 --> 00:00:20.750
collides with cold air moving down from Canada, resulting in snow and rain.

6
00:00:20.770 --> 00:00:24.890
The Global Precipitation Measurement (GPM) mission observed the storm, which dumped

7
00:00:24.910 --> 00:00:28.980
8 - 14 inches of snow over southern Maine and New Hampshire.

00:00:29.000 --> 00:00:33.080


9
00:00:33.100 --> 00:00:37.160
GPM's radar detected the storm's front as a deep layer of rain that abruptly ended south of

10
00:00:37.180 --> 00:00:41.180
Cape Cod.

11
00:00:41.200 --> 00:00:45.310
This suggested a strong temperature gradient in the lower atmosphere,

12
00:00:45.330 --> 00:00:49.460
This suggested a strong temperature gradient in the lower atmosphere,

13
00:00:49.480 --> 00:00:53.640


14
00:00:53.660 --> 00:00:57.840
which is a key ingredient for strengthening the storm.
