NOAA announced today that another weak La Niña will influence our winter weather pattern and for Montana this usually locks us into a colder than normal and wetter than normal winter season.
This is the second year in a row that a weak La Niña to impact our winter season weather.
NOAA scientists say there is a greater than 50% chance that this La Niña could linger through this winter into the early Spring.
WHAT IS Ls Niña?
In the central equatorial pacific ocean sea surface water temperatures are colder than normal due to upwelling of colder water reaching the surface. This can influence global weather and climate patterns, similar to an El La Niño but not in the same way.
We are hopeful that this winter season will be good to Montana with abundant snowpack and great skiing. If so, we should be in good shape for early summer water needs for irrigation and recreation. However, this is not a guarantee on a slow fire season for next summer to early fall.
Regardless of the winter impacts our mountain snowpack is melting out earlier than normal with a warming climate change. So despite a wonderful winter with healthy mountain snowpack our summer fire seasons can still be very devastating as we found out in 2017. Drought concerns will also continue across most of Montana heading into this winter season and into next year.
