Santa Catarina: Freezing temps (-5.1°C) and frost give way to 25°C heat
Santa Catarina experienced a frigid dawn on Thursday, June 16th, with temperatures plummeting to -5.1°C in Bom Jardim da Serra and frost observed in São Joaquim. Despite the intense cold in the early hours, the forecast predicted a warm afternoon, with highs ranging from 20°C to 25°C across the state. São Joaquim recorded a low of -1.67°C, while other locations like Urupema and Urubici registered -0.5°C and 0.04°C, respectively. Images captured by local resident Mycchel Legnaghi showed vegetation covered in ice, illustrating the dramatic temperature shift. The Epagri/Ciram forecast indicated stable weather with sunshine and scattered clouds, though isolated morning fog was possible. Temperatures were expected to be lowest at dawn and dusk, rising significantly during the day. A warm air mass is influencing Santa Catarina, contributing to the rapid temperature increase. Winds were predicted to be from the northeast, ranging from light to moderate with gusts of 50 to 70 km/h, particularly in the western and southern coastal regions.
This extreme diurnal temperature variation in Santa Catarina highlights the complex interplay of weather systems. The rapid shift from sub-zero frost conditions to daytime highs of 25°C suggests a dominant warm air mass overriding a transient cold front, potentially exacerbated by atmospheric conditions influenced by phenomena like El Niño. Such volatility underscores the challenges for agricultural planning and infrastructure resilience in regions susceptible to rapid climate shifts. Understanding the drivers behind these amplified temperature swings is crucial for developing adaptive strategies in the face of a changing climate, where predictable seasonal patterns may become less reliable.
