Thermal dome
A strong ridge hangs over North America due to favorable high winds. The atmospheric system allows abnormal temperatures to rise in Canada. In the United States, records were shattered last week, especially in North Dakota and Montana. The ridge is moving east, and unusually hot temperatures are forecast for the central and southern states, including Texas.
Also note that the water temperature in the Gulf of Mexico is unusually hot. Temperatures above 20 C are expected in some places.
