A strong ridge continues to be planted across the middle of North America, blocking up the weather pattern and bringing a lot of warm air to the U.S. and Canada. However, a big trough in the Pacific will try its hardest to push the ridge out. In doing so, it will send a lot of...

Next week's forecast rainfall across many of the main growing areas across South America calls for below-normal precipitation and drier-than-normal conditions may continue to plague Argentina.

Rising values in the Southern Oscillation Index support the idea of La Nina development sooner rather than later in the 2024 growing season.

An upper-level ridge in the West will shift into the Central U.S. towards the end of January into early February, providing a taste a spring to the Midwest and Plains.

Cold arctic air has flooded the U.S. and Canada during the last week and another burst of harsh cold has hit the end of this week and into the weekend. But that will quickly change next week with temperatures returning to much-above-normal levels as the upper-air pattern...

Rain and snow in the past month and half have brought mixed drought easing west of the Mississippi River.

Although weather conditions have been really good across much of Argentina in recent months, a dry stretch through the end of January could cause some concerns.

Drought topped the record-breaking list of billion-dollar weather and climate disasters in 2023.

2023 brought a big change to the main climate driver, as La Nina conditions in the Pacific Ocean abruptly changed to a very strong El Nino. 2024 will bring a similar but opposite transition as El Nino quickly fades and La Nina is expected to return this summer.

2023 brought a big change to the main climate driver, as we saw La Nina conditions in the Pacific Ocean abruptly change to a very strong El Nino. 2024 will bring a similar but opposite transition as El Nino quickly fades and La Nina is expected this summer.

A bigtime winter storm barreled through the middle of the country early this week. A second one will follow a very similar path, bringing more heavy snow, potential blizzard conditions, heavy rain and severe weather. But this time it will be followed by a blast of arctic air due to...

The Pacific Ocean move to El Nino brought drenching summer and fall rains to the Plains while bypassing large areas of the Midwest.

It has been a warm winter so far for so much of the U.S. and Canada as the polar vortex has been on the other side of the world. But those of us in North America will see it spend some time here for mid-January.

A deep trough moving into the Western U.S. this weekend will produce a monster storm system for the Central and Eastern U.S. Monday through Wednesday. Widespread impacts including heavy rain, strong to severe thunderstorms, heavy snow, and potential blizzard conditions are all...

A consistent and often unmovable ridge dominated North America in December, as is often the case during El Nino. That proved to be the main reason for a Top 5 warmest December on record for the northern tier of the U.S.

A strong low-pressure system on Christmas Eve and Christmas Day hit the Plains, Delta and Midwest. The system brought a range of weather impacts to these regions, including well-above-normal temperatures, heavy freezing rain, snowfall and widespread rainfall.

Greenhouse gas-related warming trends accelerated across the far north.

A storm system will move through the middle of the country in the days surrounding Christmas, bringing widespread impacts on multiple days, with possible heavy rain, strong winds and severe weather. But there is a lot of uncertainty in how this storm will develop and where and...

Extreme dryness shows little chance of significant recovery in this El Nino winter.

While the northern reaches of the country have a pretty good chance of a white Christmas, they're not 100%. This year is looking like having snow on the ground is going to be pretty tough to do.
