The active pattern across the West continues over the next five days with two additional storm systems lined up. The jet stream will move both through California and the Pacific Northwest. In the Northeast, a large, warm storm systems moves through with rain/snow on Friday then colder air sweeps in.
We're still on El Niño watch. Official forecasts continue to call for a 65 percent chance of a full-blown El Niño before the end of winter. But sea surface temperatures in the South Pacific have cooled since December 2018. Nonetheless, the transition from La Niña last winter to pseudo El Niño this winter has created momentum in the atmosphere. As a result, the storm track has shifted further south across the West. I expect that pattern to continue for the remainder of February and March.
