Cold continues in the Valley and region, but is losing strength; A new cold front should arrive in the next s After causing frost and a thermal sensation of -1.3°C in Campos do Jordão, the cold continues over the next few days, but gradually loses strength in the Paraíba Valley and region. Next week, a new cold front should bring temperatures down again, according to Cemaden (National Center for Monitoring and Alerts for Natural Disasters). According to meteorologist Giovanni Dolif, from Cemaden, the cold is caused by a mass of polar air that acts over the region after the passage of a cold front. "After the passage of the cold front at the beginning of the week, we are under the influence of a cold, icy air mass, typical of the month of July, which on average is the coldest month of the year," he said. The early hours of this Wednesday should continue with low temperatures. In Vale do Paraíba, thermometers must stay below 10°C. In Serra da Mantiqueira, minimum temperatures can drop below 5°C, with the possibility of frost. On the North Coast, the forecast is around 12°C. ?

The maximum temperatures should be between 10°C and 12°C above the values ??recorded in the early hours of the morning. The National Institute of Meteorology (Inmet) also issued a warning of potential danger for low air humidity, valid from 12pm to 6pm this Wednesday (15). Relative air humidity can vary between 30% and 20%, which requires attention to hydration and exposure to the sun in the hottest hours. Thermal range According to Dolif, the rise in temperatures will be slow, of around 1°C to 2°C per day. As a result, the difference between minimum and maximum temperatures — called thermal amplitude — should increase and could reach around 15°C. "Autumn and the beginning of winter were very cold, with more clouds and more rain. The impression is that this scenario has changed. We will have firmer weather and more sun. The temperatures do not characterize a heat wave, but we will have less cold periods", said the meteorologist. The forecast is that temperatures will rise a little more over the weekend. Starting next Tuesday (21), the approach of a new cold front should cause a new drop in thermometers in the region.
