It takes more than just a trough of low pressure to develop an Alberta Clipper or Colorado Low, which are the biggest winter storms in Manitoba. It also takes humidity, temperature changes and a host of other variables coming into play.

A weak La Niña is in play again this winter, but its effects aren’t clear
Three distinct factors are likely to drive the type of weather farmers and ranchers experience in Manitoba this winter, Daniel Bezte writes, starting this issue with a look at the atmospheric event known as La Niña.
El Nino to continue through Northern Hemisphere spring, U.S. forecaster says
Reuters — El Nino weather conditions will continue through the Northern Hemisphere during April-June 2024 with a 62 per cent chance, a U.S. government weather forecaster said on Thursday. “Above-average sea surface temperatures (SST) across the equatorial Pacific Ocean were indicative of a strong El Nino, with anomalies increasing in the central and east-central Pacific
World could face record temperatures in 2023 as El Nino returns
New record highs 'more likely than not'
Brussels | Reuters — The world could breach a new average temperature record in 2023 or 2024, fuelled by climate change and the anticipated return of the El Nino weather phenomenon, climate scientists say. Climate models suggest that after three years of the La Nina weather pattern in the Pacific Ocean, which generally lowers global
U.S. forecaster sees 62 per cent chance of El Nino developing during May-July
Argentina, parts of U.S. could benefit; Asian crops may not
Reuters — A U.S. weather forecaster on Thursday predicted a 62 per cent chance of the El Niño phenomenon developing in the Northern Hemisphere during May-July, and a strong chance toward end-year, likely compounding risks to crops across the globe. “The coastal warming in the eastern Pacific may foreshadow changes across the Pacific basin. Therefore,
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
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,
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
