The southern storm track this season has walloped us with frequent storms and record-setting precipitation. BUT that’s not necessarily because of El Nino. The numbers actually bear out that Mid-Atlantic precipitation is about average during El Nino years.
Check out the following graphic: It shows precipitation anomolies from previous El Nino years for Jan., Feb., and March. You’ll notice Virginia is in a “no change” zone.
a snippet from the Advisory:
potential El Niño impacts include above-average precipitation for the southern tier of the country, with below-average precipitation in the Pacific Northwest and Ohio Valley. Below-average snowfall and above-average temperatures are most likely across the northern tier of states (excluding New England), while below-average temperatures are favored for the south-central and southeastern states.
