Executive Summary: The Climate Impact Company month 1-3 ahead forecast is updated. The forecast indicates minor but important changes. In June, the dryness in the Midwest shifts farther north to Minnesota. The Great Basin to western Great Plains is wetter and the southwest quadrant of the U.S. is not as hot. The East is temperate during June while Texas is marginally hot. In July, the Northeast and much of Texas is hot as previously indicated while the Great Plains are temperate and trend wetter across the southern Plains. July stays hot and mostly dry in the Northwest. The August outlook maintains a cool pattern in the Great Plains with increased wet weather risk helping to ease drought concerns. The Southeast and central Gulf States stay wet in August in anticipation of tropical cyclone activity. The far Northern U.S. and Southern Canada finish the summer season warmer and drier than normal. High impact climate discussion energy: A hotter than normal summer remains in the forecast. However, the ability to produce a stagnant hot upper ridge over the U.S. appears difficult this summer season. Therefore, long-lasting important anomalous heat present in recent summer seasons is not expected. The two exceptions are the Northwest and possibly for a 6-week period in the coastal Northeast Corridor. Therefore, national CDD forecasts are lower this summer compared to the last 3 (summer) seasons. ERCOT and PJM-East remains hot for JUL/AUG. High impact climate discussion agriculture: The central Great Plains drought does not observe a dry summer and consequently drought is not likely to worsen and more likely to ease. Drought expanding northeastward to Iowa, western Illinois, and northern Missouri is a greater concern. The drought expansion extends to July followed by wet risk suppressing drought risk. The southwest Great Plains is trending wetter. June 2023 outlook: No major changes BUT many adjustments to the first month of meteorological summer climate forecast. The dry concern in the Midwest States shifts slightly northward from Iowa to Minnesota. The Canadian Prairies are mostly dry but not as dry as the previous forecast. Western Canadian warmth extends to the northwest quadrant of the U.S. slightly more forcefully. However, California to Texas is not as hot as previously indicated. The wet anomaly in the central Rockies indicated in the previous forecast extends farther westward. Finally, a wet bias remains indicated in the Southeast States although less aggressively than previous. The East is temperate while New England is dry and could be warmer than indicated. The climate drivers are a possible onset of El Nino, lack of Madden Julian oscillation (MJO) presence, weakening cool Pacific decadal oscillation, and a vigorously warm North Atlantic.

July 2023 outlook: The expected SSTA trend is warming of the western North Atlantic and Northeast Pacific supporting stronger high pressure aloft leading to anomalous heat risk on each coast. Anomalous heat is also likely across the southwestern Texas drought area and extending to 4-Corners. However, just to the north, wet weather prevails from Utah to the southwest Great Plains. The core of the Great Plains drought, located in Kansas as summer starts, continues to shift east and northeast toward Iowa. The East remains wet during mid-summer as a weak upper low entrains buoyant low atmospheric moisture across the warm SSTA pattern in the western North Atlantic. Nevertheless, periods of hot and humid weather remain in the Northeast Corridor forecast. The Northwest stays hot and mostly dry.

August 2023 outlook: The late summer forecast maintains a hot risk in the Northeast, southwest Texas, and the Northwest U.S. However, in stark contrast, an upper trough rests over the Great Plains bringing a cooler than normal end to meteorological summer as previously indicated. The one change in the forecast is wetter, due to the trough, in the central Great Plains. Wet weather also extends northward from the Gulf States possibly related to tropical cyclone influence. The late summer rainfall forecast favors central Great Plains to Midwest U.S. drought concerns beginning to ease possibly significantly. Southern Canada and the far Northern U.S. are drier and warmer than normal in August promoting a dangerous fire risk to some of that stretch. The Southwest U.S. is drier and hotter than normal due to a weak wet monsoon. Fig. 5-6: The Climate Impact Company August 2023 temperature and precipitation outlook.
