In Europe, a worse-case scenario is unfolding. The late June heatwave core has shifted across Eastern Europe this week while beginning to regenerate in Southwest Europe/Northwest Africa (Fig. 2). In the medium range, combining GFS and ECM, the Southwest Europe heat expands and intensifies reaching U.K. days 6-10 and continues to expand eastward in the 11-15-day forecast. The hottest weather within this new heatwave expansion is across France.

The consensus of all operational models and their U.S. population weight CDD projected for the week ending July 9, 2026, is 100 CDD which would eclipse the previous hottest week of the last 10 years at 99 CDD recorded for the week ending July 23, 2022, and July 30, 2016.

Increased westerly wind in the middle latitudes is characteristic of an El Nino climate, particularly during the winter season. Increased westerlies in the middle latitude is well represented by positive phase of global atmospheric angular momentum (GLAAM) index.

Severe drought in the Mid-Atlantic region is a significant concern as July approaches. The risk of over-achieving heat is significantly elevated across a large drought area during July. The hot bias provided by extreme dry soil moisture can easily overwhelm synoptic level forecasts and that’s the concern in July for the Mid-Atlantic region. The 12Z GFS Mid-Atlantic heat is hard to ignore.

The Climate Impact Company month 1-4 precipitation outlook for India is updated. The forecast is driven primarily by warm ENSO analog years and partially by marginally positive phase Indian Ocean dipole (+IOD). The outlook does not completely fail the wet monsoon due to impacts of El Nino. However, key crop areas in Central India are likely to encounter developing and strengthening drought during the next several months.

Searing U.S. Heatwave Emerging, Expands This Week
Excessive Heat Warning and Watch areas plus Heat Advisories are expanding as the heatwave of late June/early July continues to develop/expand. Key elements of this heatwave are certainly the afternoon temperatures but adding high dew points, therefore dangerous heat index and warm nights which limit recovery for electric grid systems, a problem that accelerates over a few days and certainly evident across much of PJM, especially PJM-East this week.

ALERT Issued for Hot/Dry Weather Centered on Western U.S. Corn Belt Later July
Climate Impact Company issues an ALERT for accelerating dry soil in the Western Corn Belt during the 16-30-day period, also the peak hottest time of summer climatologically. ECM and AI GC differ on whether hot weather is present, but each forecast agrees on dryness.
