Latest Summer Outlook for U.S. Implicates Northwest with Possible Record Heat/Drought Expansion

The Climate Impact Company month 1-4 ahead climate outlook is updated. There are some changes from the earlier issued summer 2026 outlook and forecast confidence has increased as predictors are increasingly clear. High impact climate is likely and will affect public safety and market interests. Most prominent is the hot climate forecast for summertime across the West and Northwest U.S. with record heat possible the first half of summer in the Northwest and possibly late summer in California.

Do Wet Soil Regions Influence Following Summer Climate in the U.S.?

Is there a relationship between summer climate and large areas of wet soil regions during spring? Yes! And the relationship can be profound and demonstrates a residual effect on mid-level troposphere pressure systems elsewhere. Currently, the Great Lakes region is in a historically wet soil moisture regime which continues to intensify. This region will enter the 2026 summer season with soaking wet soil conditions.

Cold Risks to Midwest and Northwest Great Plains

After a short-term freeze threat in the U.S. Corn Belt more winter weather is on the way for the Northwest Great Plains and Canadian Prairies Spring Wheat areas. Beginning Thursday and lasting early next week, a snowy/windy pattern emerges. Morning low temperatures are pushed into the 20’s for several mornings across the Northwest Great Plains and 10’s/20’s for the Canadian Prairies.

Central/South Great Plains Drought Receive Helpful Rainfall East, Not Much Rain West

In the High Plains, D0-D4 aerial coverage lowered slightly, but (more) intense drought (D2-D4) increased by 4%. In Kansas, soil conditions are steadily shifting drier (except in the northeast). The South U.S. drought is impressive with sharpest declining conditions in Arkansas. Similar with the High Plains, D2-D4 drought increased slightly in mid-April.

PJM West Summertime Heat Risk is Suppressed

The warm season (MAY-SEP) 2026 cooling degree days outlook for selected cities across the PJM Service Area indicates a split (climate) pattern. PJM-West is susceptible to El Nino-fueled cloudiness and wet weather likely to suppress warm season cooling demand.

Major Drought for Europe During Summer 2026

The Climate Impact Company Summer 2026 climate forecast indicates evolution of a major drought in Europe which extends to Southwest Russia. Accelerating the drought is increasing strength of anomalous heat. The forecast is based on developing strong El Nino, a prominent North Atlantic warm hole (NAWH), and emerging heatwaves in the Norwegian Sea and Mediterranean Sea.

Plethora of East Great Plains Severe Weather This Week

Negative Pacific North America (-PNA) pattern assures a cool regime in the West clashing with very warm temperatures in The Central and East to cause daily severe weather outbreaks into the weekend. Today, severe thunderstorms are forecast by NOAA/SPC from Texas to the Midwest States pulsing eastward to New England. The greatest tornado risk is located from Des Moines, IA to Chicago, IL. Tornado risk is evident in Oklahoma.

South America Week 2-4 Outlook: Brazil shifts drier; Hot Southeast Brazil.

MJO forcing causes a heavy rain scenario across Northern Argentina/Paraguay and Northeast Brazil the next 7-10 days. However, tropical involvement is diminished in the extended range as Brazil shifts much drier. Dry soils in Southeast Brazil increase the risk of steady late season anomalous heat.

Unusual Early Season West Pacific Major Typhoon Sinlaku Indicates Potential for Busiest North Pacific TC Season on Record

A strong westerly wind burst (WWB) in the Pacific Ocean tropics between 140E and 160E also located across warm sea surface temperature anomalies (SSTA) and robust subsurface upper ocean heat helped spawn an early season unusually strong category-5 major typhoon (Sinlaku). The ingredients helping to ignite this early season intense storm to develop are shifting eastward and will ignite El Nino in May with rapid intensification likely to follow.

Immense Subsurface Kelvin Wave East of Dateline Promises Intense El Nino Ahead in 2026

Neutral ENSO continues during early April as the Nino34 SSTA is unchanged at +0.2C. Last week, some warming was observed off the northwest coast of South America (Nino12). The subsurface upper ocean heat is MUCH warmer than normal and intensifying. The NEW Kelvin Wave features ocean temperatures 6-7C warmer than normal extending to just east of 150W and further eastward shifting is likely.
