Northern California deluge’s current rainfall level expected again

Flood risk to continue into next week

MarketsFarm — While the deluge of rain over northern California took a day’s break on Tuesday, agricultural meteorologist Drew Lerner of World Weather Inc. said the heavy precipitation would soon resume. Following the worst drought in California history, the state has been receiving very intense precipitation that’s brought flooding to its northern areas. “It will […] Read more

La Nina set to continue for third year

Other weather patterns may override temporarily

MarketsFarm — With fall soon upon North America, there’s nothing overly unusual with the continuation of La Nina, according to Drew Lerner, president of World Weather Inc. at Overland Park, Kansas. Going into its third year, some people might think this is the third consecutive La Nina — but Lerner said it’s the same one, […] Read more

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 […] Read more

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 […] Read more

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 […] Read more

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, […] Read more
