NOAA: What About Snow During La Niña Winters? This is a guest post by Dr. Stephen Baxter who is an NOAA Climate Prediction Center (CPC) meteorologist and does applied research on sub-seasonal-to-seasonal climate variability. In particular, he specializes in understanding how the middle-to-high latitude circulation is influenced by the tropics versus other processes. He also has a lot of opinions on Siberian snow cover and the role of […] Weather WeatherBrains | October 6, 2020 0 Comments

La Niña Generally Means a Colder and Snowier Winter than Normal On July 9th the Climate Prediction Center issued a La Niña watch. This means that conditions are favorable for the development of a La Niña or a negative phase of the El Niño Southern Oscillation circulation over the next six months. The CPC indicates a 55% chance of development over the time period, this product is not a forecast that […] Weather WeatherBrains | July 17, 2020 0 Comments
How a La Niña Weather Pattern Will Potentially Effect Colorado’s Mountain Ranges Next Winter The NOAA predicts that there is a 50-55% chance that next winter will be influenced by a La Niña weather pattern. Of course, it being only July, predicting a La Niña is still “going out on a limb for a long-range forecast,” according to Colorado meteorologist Chris Tomer.

NOAA Posts 2020-2021 La Niña Watch | Snowfall Totals Expected to be Above Average in Pacific Northwest, Drier for Intermountain West The NOAA released a La Niña watch on Thursday, July 9. The NOAA is currently giving a 50-55% chance of a La Niña pattern developing in the fall and lasting through winter, though those numbers are certainly subject to change. La Niña systems generally indicate colder equatorial ocean temperatures, which forces the jet stream further north, delivering above-average precipitation to […] Weather Clay Malott | July 14, 2020 0 Comments
NOAA Issues La Niña Watch: 50-55% Chance of La Niña Developing in Fall and Lasting Through Winter Photos and text originally by Emily Becker on Climate.gov. ENSO is still in neutral, and likely to continue so through the summer. However, the 50-55% chance of La Niña developing in the fall and lasting through winter means NOAA has hoisted a La Niña Watch.
