La Nina conditions to continue, but odds lower into winter

Reuters — Chances for La Niña are expected to gradually decrease from 86 per cent in the coming season to 60 per cent during December to February in 2022-23, a U.S. government weather forecaster said on Thursday. The La Niña weather pattern is characterized by unusually cold temperatures in the equatorial Pacific Ocean. According to

La Niña likely to continue into spring, U.S. forecaster says

Reuters — La Nina conditions are likely to continue during the Northern Hemisphere spring, a U.S. government weather forecaster said on Thursday. The La Niña weather pattern, characterized by unusually cold temperatures in the equatorial Pacific Ocean, has a 67 per cent chance of persisting from March through May this year, the National Weather Service’s

La Niña introduces itself with Prairie cold snap

MarketsFarm — The frigid conditions which had enveloped the Prairie provinces in recent weeks is a sign La Niña has come again, according to a Kansas-based meteorologist. Since mid-December, the Prairies have been in a deep freeze beginning with temperatures at least 10 C below-normal. Since the holiday season, many towns and cities in the

Prairie winter weather a sign of La Nina repeat

Full effects won't be seen for a while yet

MarketsFarm — December marks the start of what meteorologists call “meteorological winter” — and this winter, the Pacific Ocean phenomenon known as La Nina may be rearing its head once again. La Nina (Spanish for “little girl”) is a climate pattern detected over the Pacific every few years where cooler water pools at the equator

Another La Nina winter predicted

Polar vortex to chill Prairies, more snow further east, AccuWeather says

Data compiled by a U.S. federal weather forecasting agency show La Nina conditions have developed over the central Pacific Ocean and are likely to linger through February. And La Nina, in turn, is expected to produce hard cold snaps over the Prairies, above-normal precipitation over southern British Columbia and relatively mild temperatures with more snow

La Nina done, U.S. CPC says

Neutral weather likely through summer

Reuters — A U.S. government weather forecaster said on Thursday La Nina has ended and El Nino-Southern Oscillation (ENSO) neutral conditions are likely to continue through the Northern Hemisphere summer. “ENSO neutral” refers to periods in which neither El Nino nor La Nina is present, often coinciding with the transition between the two weather patterns,


Thunderstorms require a significant difference in temperature between two areas, such as when a front cuts through a region.

Thoughts on thunderstorms and a warm March

Just having a very hot day doesn’t create the conditions for a storm

The phrase “If you don’t like the weather, wait a minute” is never so true than during the spring across the Prairies and so far, this spring is living up to the saying. As we get ready for May, thoughts begin to switch from snowstorms and cold snaps to heatwaves and thunderstorms. So for this

WMO officially calls a La Nina winter

MarketsFarm — A La Nina weather event has officially developed in the Pacific Ocean and is expected to continue into 2021, affecting temperatures, precipitation and storm patterns around the world, according to the World Meteorological Organization (WMO). The global declaration of the La Nina event by the United Nations’ agency will be used by governments
