Sunday in Sacramento started out on the cool side, with many spots in the upper 50s in the morning, before a warm-up into the low 90s by midafternoon on Sunday, July 19. Skies will stay mostly sunny through the day with light southwest winds off the Delta, and humidity will drop into the lower 20s to 30s by late afternoon. That warm, dry combo is enough to raise elevated fire-weather concerns in parts of the valley and nearby foothills this afternoon and evening. Plans may need to stay flexible, since monsoonal moisture is expected to return and could spark isolated storms over higher terrain later this weekend into next week.
Afternoon Heat And Thunderstorm Chances
Look for a high near 92°F this afternoon with southwest winds of about 2 to 7 mph. Delta gusts could reach 15 to 20 knots (roughly 17 to 23 mph) at times, especially near the river and islands. Relative humidity will dip into the 20s to 30s in portions of the valley, creating the drier conditions that triggered elevated fire-weather concerns in a few areas. Monsoonal moisture is forecast to slide into the region Sunday and hang around into midweek, bringing a small chance for isolated showers or thunderstorms, mainly over the Sierra, the northeastern foothills, and parts of the northern valley. Most storms should be on the wetter side, but a few could still crank out brief heavy rain or gusty winds. These details appear in the local forecast and discussion from the National Weather Service.
Where To Cool Off And What To Watch
If you need a break from the heat, Sacramento County has activated daytime hot-weather respite sites during recent heat spells, including the North A Shelter at 1400 North A Street. Callers are advised to check capacity by dialing 2-1-1 before heading over. The county has coordinated those activations with partner organizations in response to forecasts like this one, offering a cool place to rest, charge devices, and get a meal when sites are open, according to the county notice. For most residents, simple precautions should be enough for a low-90s day: drink plenty of water, find shade during peak sun hours, and avoid strenuous outdoor work in the middle of the day.
Bottom line: expect warm and mostly sunny conditions today, with only a small chance of isolated storms in the hills and parts of the northern valley into midweek. Check updated forecasts before heading outside, and secure lightweight items this evening if you are near the river, where gusts may pick up.
