Fresno was mostly cloudy and 57 degrees at 6:05 a.m. Saturday, with a high near 69 forecast. The day still has a wetter finish in store: the National Weather Service forecasts a chance of rain during the day, with showers and a possible thunderstorm forecast Saturday night. The latest Fresno forecast and airport observation show the morning conditions and updated outlook.
Rain Arrives Before Halloween Night Gets Stormy
Saturday’s high is forecast near 69 degrees, with rain possible during the day. For Fresno-area communities, the National Weather Service gives a 35% to 50% chance of at least 0.1 inch by 5 p.m. and a 40% to 50% chance of at least 0.25 inch by 11 p.m. Showers and a possible thunderstorm are forecast Saturday night, when the chance of precipitation rises to 80%. The updated point forecast and Hanford’s rainfall probabilities provide the details.
The rain threat extends beyond trick-or-treat hours: the National Weather Service’s Hanford office expects more substantial precipitation across its San Joaquin Valley forecast area from Saturday evening through midday Sunday, with a 40% to 65% chance of at least a half-inch of rain. The office says the broader storm is tied to a trough and low-pressure system moving into California. The Hanford forecast discussion lays out the regional outlook.
Saturday night stays unsettled, with showers and possibly a thunderstorm expected before 2 a.m., followed by rain after 2 a.m. The low should settle near 55, making for a damp and chilly finish to outdoor Halloween plans. The National Weather Service’s Fresno forecast gives an 80% chance of precipitation overnight.
Sunday Improves Quickly
Sunday’s high should be near 67, with a 30% chance of rain before 11 a.m. Skies are forecast to clear gradually after midmorning. The updated National Weather Service forecast gives the Sunday temperature and rain outlook.
Dryer, Cooler Nights Follow
Fresno’s forecast settles down Monday through Friday, with sunny or mostly sunny afternoons and highs near 68 to 70. Overnight lows are forecast around 49 to 52. Fog is possible Monday and Tuesday. The National Weather Service’s extended forecast lists the day-by-day outlook.
Drivers heading into the Sierra should note that snow is expected at higher elevations, where a winter weather advisory remains in effect through Sunday morning. For Fresno, the main takeaway is simple: keep rain gear close Saturday evening, then expect a cleaner and brighter Sunday afternoon.
The Sierra advisory does not cover Fresno city, but it flags difficult travel at higher elevations: the National Weather Service expects 4 to 8 inches of snow from 7,500 to 9,500 feet and as much as 18 inches above 9,500 feet, with gusts up to 35 mph. The advisory runs from Saturday morning through 7 a.m. PST Sunday, Nov. 1, and warns that travel could become very difficult. The Fresno County alert lists the affected mountain areas and precautions.
