A strong cold air mass of polar origin will spread a lot of cold air over central-southern Brazil in the coming days and lower the temperature also in the capitals.
One this Wednesday a strong mass of cold air of polar origin begins to advance over central-southern Brazil, April 19, causing a sharp drop in temperature in the states of the southern region and in parts of Mato do Grosso do Sul and São Paulo. During the week, including the extended April 21 holiday, this cold air sweeps across the Southeast and Midwest, leaving increasingly colder nights in the south-central part of the country.
AND cold air mass will be strongest in 2023, so far, and will have the potential to cause the lowest temperatures of the year in all capital cities in the Southern region, in almost all capital cities in the Southeast and Midwest. It is possible that some of the cold air reaches Rondônia and Acre causing a slight cold and also with the possibility of record cold even in the capitals of these states.

Some capital cities may experience record cold more than once during the passage of this strong cold air mass in the coming days.
Porto Alegre and Curitiba are expected to set new cold records for 2023 with temperatures just below 10C.
In the capitals Florianópolis, São Paulo and Campo Grande, new minimum temperature records for 2023 are expected to be just above 10°C.
Current low temperature records
For accounting entries in the capitals that have manual and automatic measurement, Climatempo adopts as a criterion the values recorded in conventional meteorological stations, as they have a much broader historical data and allow comparisons with a more distant past compared to automatic stations.
An example of this situation: the conventional weather station in Belo Horizonte, in the neighborhood of Santo Agostinho, has been measuring since 1910. The automatic weather station in Pampulha has been recording data since 2006.
Discover the lowest temperatures recorded this year in the capitals of the South, Southeast and Midwest, Rondônia and Acre until 04/18/2023, according to measurements by the National Institute of Meteorology in its network of conventional weather stations (reading the instruments carried out by a person) and automatic (data obtained without manual contact).
