It can get hot in a parking lot. Lahti has an official weather station where the air temperature and humidity are measured according to the international standard, that is, on a lawn inside a white wooden box with large horizontal openings on the sides covered by slats so as to protect the inside from direct sunlight and allow the air to circulate freely. The box has to be exactly two meters above the lawn. At the weather station, the air temperature is now 23,9 C which will probably be the daily maximum. According to the forecast, the daily maximum will be one degree higher tomorrow. There will also be rain showers and thunder tomorrow evening,
