The winter storm season of 2018-2019 brought a persistently wet storm track from the Southwest to the Midwest that helped bring a big spring flood to many of the rivers in the nation’s heartland.
There were a total of 24 named winter storms in the season, which began when Avery formed in mid-November and ended in late April when Xyler dissipated. This number of storms is near the 6 year average since storms have been named by The Weather Channel.
A common track from the Great Basin and Intermountain West through the Central Plains and into the Great Lakes emerged during the season while typical nor’easters were largely absent minus a few weaker storms.
Much of the first half of winter storm season was dominated by a slower than usual pacing of storms. Widespread high-impact winter storms frequented cities roughly every two weeks.
Despite the common track through the Plains, most winter storms this season were named due to population criteria.
The first two months brought several high-impact winter storms.
In fact, Winter Storm Diego was rated a Category 3 storm by the National Centers for Environmental Information (NCEI) using the Regional Snowfall Index (RSI). The RSI rates storms based on how much snow they drop, how much area is covered by snowfall and how much population is covered. Diego brought very heavy snow to parts of the Southeast in December.
