325

Low-temperature values ​​with frosts begin to dominate the Altiplano and mountains of Mexico, anticipating that this condition will strengthen by the end of the week, as well as scattered rains and storms. Remember that the cold will increase as November passes.

After the passage of cold front number 6 last week, cold and dry air invaded several regions of our country, considerably reducing the rains with warmer afternoons, but highlighting cold nights-nights from Chihuahua to the center including the Valley of Mexico. The extreme minimum values ​​have hovered around -5 to 0 ° C with frosts and, everything indicates that the intensity of the cold will increase from this weekend once the front number 7 has crossed and its polar air mass that this afternoon of Wednesday it will tour the northeastern states.

This contrasting situation is typical under the La Niña phenomenon, which, as you will recall, has been established since the beginning of October. The air is drier, allowing more periods of sun to appear during the afternoons and the temperature to rise towards a more temperate to hot environment, but as soon as night falls and during the early morning, the heat is quickly and easily lost, cooling the surface until frost is generated; this is just beginning …

Precipitation forecast

Between the afternoon-night of today and the first hours of Thursday, heavy rains/storms are expected between CoahuilaNuevo León and Tamaulipas mainly in their central-north municipalities with punctual accumulations of 40-70 mm or higher, accompanied by gusts of wind and hailstorms, as well as flash floods, although of course, will be very beneficial rainfall in the region.Very beneficial rains will occur in northeastern Mexico as the cold front 7 passes, although they may be accompanied by hail, in addition to generating urban floods.

From Thursday to Saturday, the front will travel the Slope of the Gulf until slowly reaching the Yucatan Peninsula over the weekend; Scattered precipitations of 5-15 mm with points of 30-50 mm in 24 hours are probable between Veracruz, Zacatecas, San Luis Potosí, Hidalgo, Puebla, Tabasco, Campeche, and Quintana Roo. Outside the frontal system, humidity from the Pacific can generate isolated showers/storms between Nayarit, Jalisco, Michoacán, Colima, the State of Mexico, Guerrero, Morelos, and Oaxaca in the evening hours.

Effects of polar air in Mexican territory

The notable thermal decline is already perceptible on the Mexico-Texas border, extending to the entire northeast of the Republic this Thursday generating temperatures of 5 ° C in mountains and 10-15 ° C in low areas with drizzle, fog and wind that can increase the feeling of cold. The polar mass, although weak, will travel through the Gulf of Mexico causing a weak NORTH with gusts of 40-60 km / h on average, being likely higher in the center of Veracruz and the Isthmus-Gulf of Tehuantepec.

This polar mass will reach the Yucatan Peninsula on the weekend, generating very cool sunrises of 15 ° C and warm afternoons of 25-30 ° C; while in the Altiplano, the local effects of altitude and mountains would “enhance” the mass so that the nights-early mornings cool even more, being probable minimums of -7 to 0 ° C in valleys and forested areas of ChihuahuaDurangoHidalgoPueblaState of MexicoMexico City, Veracruz and Morelos, extending next week, while in the afternoons it would be around 15 to 25 ° C.

In the rest of the country (northwest, west and south) a hot to very hot environment will persist in the afternoons with highs of 30-40 ° C and barely cool sunrises. We are entering the autumn season and it is important to take care of your health in the face of temperature changes; be aware of the weather updates through Meteored, where you will be followed up in the event of any emergency that arises.
