Monsoonal moisture is invading the Northern Sacramento Valley. There are high level clouds now. Normally the wet bulb starts decreasing at daylight. Not today. People living in the South would shrug at 70° wet bulb but for me, it’s borderline intolerable. #CAWx Screenshot of a weather data table from mesowest.utah.edu, showing observations for 07/13/2024 at various times from 5:50 AM to 9:50 AM PDT. The table includes columns for time, temperature, humidity and wet bulb. It shows temperatures going up as humidity goes up resulting in ever higher wet bulbs. At 09:50 it was 86° with a relative humidity of 47% and wet bulb of 70.5°F.
