Residents of Mexico City (CDMX) and the State of Mexico (Edomex) should prepare for significant rainfall and cooler temperatures as the forecast warns of thunderstorms and possible hail on February 21, 2025. According to the Servicio Meteorológico Nacional (SMN), the adverse weather will be largely influenced by the stationary Front Cold 28 interacting with low-pressure systems over the region.
For Friday, February 21, residents can expect cloudy skies and temperatures ranging from 10 to 12 °C during the morning. By the afternoon, the maximum temperature may reach 20 to 22 °C, creating stark contrasts from the chilly morning. The forecast indicates scattered thunderstorms along with the possibility of lightning strikes, particularly challenging for those considering outdoor activities.
The SMN has reported, "Se prevén precipitaciones con chubascos dispersos para la ciudad capital y el Edomex, los cuales se podrían acompañar con descargas eléctricas" (precipitation with scattered thundershowers is expected for the capital city and Edomex, which could be accompanied by lightning strikes). This alert means inhabitants should definitely carry umbrellas and rain gear if venturing outside.
Temperatures will drop as low as -5 °C during the night, particularly affecting higher elevations, with areas like Toluca experiencing minimums of 5 to 7 °C. The cold air mass associated with the front is expected to maintain the colder temperatures across various regions, creating frost warnings.
On February 20, the forecast predicted light rain and localized thunderstorms earlier in the day, beginning from around 15:00 to 18:00 hours. Residents are advised to be cautious during this time, especially with wind gusts reaching up to 40 km/h. The Spanish report shared details about the expected conditions, noting, "La temperatura mínima pronosticada para la CDMX será de 10 a 12 °C y la máxima de 20 a 22 °C" (the minimum temperature forecast for CDMX will be between 10 to 12 °C and the maximum will be between 20 to 22 °C).
It is also anticipated, due to the interactions between the cold front and the tropical humidity, heavy rain will impact states like Veracruz, Chiapas, and Tabasco, where flooding could result from the intense precipitation. These areas are expected to receive significant amounts of rain, with some locations receiving amounts between 50 to 75 mm, prompting the government to issue warnings.
The SGIRPC has activated yellow alerts for specific municipalities experiencing heightened risk of rain and hail, implementing safety measures. They encourage residents to take precautions, such as clearing drainage systems and securing windows. This proactive approach aims to mitigate the chances of flooding or other weather-related incidents.
On Friday, the weather won't improve immediately, as winter's chill lingers with temperatures remaining low across the area. Experts maintain the importance of dressing warmly, especially during early mornings and late evenings to avoid health risks due to falling temperatures. Sport events scheduled for the weekend should also be monitored, as rain may affect participation and safety.
Overall, the weather forecast for CDMX and Edomex signals potential disruptions as residents prepare for rain and noticeable temperature shifts. While authorities stay alert for hazardous conditions, the community is reminded of the unpredictability of weather patterns and the need for readiness.
With forecasts indicating temporary winter conditions returning soon, it won’t be long before milder weather arrives. Nonetheless, as always, it is wise to check briefing updates from the local weather agency and have necessary supplies on hand for what February 20-21 has to offer.
