Teotihuacan, Mexico. Saturday 25th February 2017. Record-high temperatures have been recorded across much of Southern USA and Mexico. The usual winter weather pattern involves cold Arctic air being driven southwards on a powerful jet stream. This month, however, the jet stream has remained well to the north, largely confined to Canada. Much of the central and southern US is sitting underneath an area of high pressure. The circulation of air around this system is allowing air to spread from the Gulf of Mexico.

This month, however, the jet stream has remained well to the north, largely confined to Canada. Much of the central and southern US is sitting underneath an area of high pressure. The circulation of air around this system is allowing air to spread from the Gulf of Mexico. Temperatures in many parts of southern Texas exceeded the landmark 100 Fahrenheit mark (38C) on 23 February, with a maximum of 107F () at Falcon Lake, close to the Mexican border. This compares with a late February average maximum of 20C (68F)
