Cold front number 12 will enter the country on Saturday, November 1, initially impacting the north and northeast. Accompanied by an upper-level trough and interactions with polar and subtropical jet streams, it will cause a marked temperature drop, rain, showers, and wind gusts in states such as Chihuahua, Coahuila, Nuevo León, and Tamaulipas.

Rain will concentrate in Nuevo León and Tamaulipas, while Veracruz and parts of Tamaulipas may see showers with electrical activity in the Huasteca Alta, Huasteca Baja, and Totonaca regions.

Isolated rains are also expected in Nayarit, Jalisco, Morelos, Mexico City, State of Mexico, and Hidalgo.
Moist air from the Gulf of Mexico and Caribbean Sea will generate scattered rains in Veracruz (Nautla, Capital, Las Montañas, and Sotavento), Puebla (Sierra Norte, Sierra Nororiental, and Mixteca), Quintana Roo, and Yucatán. Precipitation probability will be low elsewhere in the country.
