New report highlights intense western heat, shifting storm risks, and an unusually fast El Niño that could disrupt traditional farm planning.
Farmers across the west, in both the United States and Canada could be facing an unpredictable and potentially challenging stretch of weather as summer approaches, according to the latest Weekly Weather Intelligence Report released June 15 by Nutrien’s Eric Snodgrass.
The report points to a developing weather pattern that is already influencing conditions and could remain in place through the end of June, bringing a mix of extreme heat in the West and increased storm activity further east.
Heat Builds in the West as Fire Risk Climbs
One of the most pressing concerns for producers in Western regions is a surge in heat. A high-pressure ridge forming along the West Coast is expected to intensify temperatures, pushing some areas, including the Pacific Northwest and interior regions, above 86°F (30°C), with localized peaks surpassing 100°F (38°C).
While the most extreme heat is forecast for areas farther south, the broader pattern is relevant for Western Canadian farmers, particularly in British Columbia and parts of Alberta and Saskatchewan. Prolonged heat, combined with dry conditions, increases evapotranspiration rates, placing added stress on crops and pastures while elevating wildfire risk.
The pattern is being reinforced by a fast-moving jet stream interacting with a high-pressure system off the West Coast, effectively locking in warmer and drier conditions.
Storms and Flood Risk Shift East
While Western regions contend with heat, the central and eastern parts of the continent are preparing for more unsettled weather. A trough stretching from the Great Lakes toward Hudson Bay is drawing in moisture, setting the stage for severe storms and localized flooding.
Heavy rainfall is expected early in the week across the Gulf Coast region, with the risk shifting into the Midwest by midweek. Severe weather threats, including tornadoes, large hail, and damaging winds, are also anticipated across parts of the U.S. Midwest.
Although the most intense activity is expected south of the border, Ontario and neighbouring regions could still see increased storm systems and variable conditions as the trough remains in place.
Wind and Moisture Add to Complexity
Strong winds are forecast to develop across parts of the northern Plains, including Montana and the Dakotas, potentially extending into adjacent agricultural regions. These winds can contribute to soil moisture loss, increase crop stress, and complicate spraying and fieldwork.
Precipitation forecasts remain uncertain, with leading models showing agreement on southern rainfall patterns but diverging significantly across key agricultural zones such as the Great Lakes region. This level of variability is typical at this range, but it underscores the difficulty farmers face when making near-term decisions.
El Niño Developing Faster Than Expected
Perhaps the most significant factor shaping this season’s outlook is the rapid and unusually warm development of El Niño conditions in the Pacific Ocean.
According to the report, the 2026 transition from La Niña to El Niño is occurring faster than any comparable period on record, outpacing notable years such as 2023, 2015, 1997, and 1982. In addition, current ocean temperature patterns are not aligning with historical norms, with key features shifted further east than expected.
This deviation means that traditional forecasting models and historical analogs may be less reliable this season.
“No single model or analog justifies a confident summer precipitation outlook yet,” the report notes, emphasizing the need for ongoing monitoring of soil moisture levels, evolving weather models, and regional conditions.
What Farmers Should Watch Now
Looking ahead, ensemble models suggest that the western ridge and eastern trough pattern will persist into late June, maintaining the divide between hotter, drier conditions in the West and cooler, stormier conditions in the East.
Longer-range outlooks into early July continue this trend, with increased heat risk in the Interior West and a cooler bias across eastern regions. However, there are emerging signals that higher pressure could develop across the south-central United States, potentially triggering new storm patterns that could extend into the Midwest and beyond.
Sea surface temperatures in the Northeast Pacific are also being closely monitored. A warming trend in this region has historically been associated with increased summer heat in Western North America and relatively cooler conditions further east.
Implications for Western Producers
For farmers in Western Canada, the current outlook suggests the need for heightened vigilance. Heat and dryness during critical crop development stages can reduce yield potential, particularly for cereals and oilseeds.
The lack of a stable, high-confidence forecast reinforces the importance of staying informed. With this year’s El Niño behaving differently than past events, conditions could shift quickly.
A Season That May Break the Rules
While past El Niño years have often delivered drier conditions across the southern United States and more active weather in central and eastern regions, 2026 is already showing signs of diverging from those patterns.
