Today's weather in Mexico: frosts are expected

05/02/2021

During the winter season, some type of "frost" is expected, mainly in the mountainous regions and valley of Mexico. The following is a short term forecast and we will tell you about the influence of this effect in Mexico.

Frost is the decrease in air temperature with a value equal to or lower than 0°C (freezing point of water); the absence of atmospheric elements such as wind, cloudiness, low humidity content and fewer hours of solar radiation, also contribute to its origin. The contrast of different air masses (arctic-polar and tropical), contribute to temperature oscillation, giving rise to different meteorological effects throughout Mexico.

February is one of the months that is characterized by its wide thermal contrasts favored by anticyclones that are reflected in different levels of the atmosphere, meaning that we can have extremely cold and dry dawns, and hours later an increase in the ambient temperature being warmer and even depending on the region we will have the presence of humidity with some isolated rains.

The dominance of an anticyclone in the middle and high levels of the atmosphere over most of Mexico will favor the appearance of morning frosts during the dawn of Friday, an effect that will be reinforced by the loss of heat during the night and the low relative humidity in combination with the dry surface air.

Northern states, mainly in their mountainous portions, are expected to register some type of frost in the morning; among them Chihuahua, Coahuila, Durango and Sonora, where morning temperatures could register values between -5°C and 0°C.

Frosts are also expected in mountain valleys of central and southern states; Chiapas, Guanajuato, Hidalgo, northern Jalisco, northern Oaxaca and western Veracruz, where morning temperatures could register values between 0°C and 5°C; Mexico City, State of Mexico, Puebla and Tlaxcala with temperatures at dawn between -5°C and 0°C in their highlands.
