Fresno is waking Friday to haze, quiet winds and temperatures in the upper 50s, but the calm is short-lived. Halloween weekend is shaping up cooler and considerably wetter, with rain and possible thunderstorms arriving Saturday and lingering into early Sunday.
Cloudy Friday Before The Weekend Shift
Friday should stay mostly sunny with a high near 71 degrees and light southwesterly winds. Overnight temperatures will dip to around 56. The National Weather Service also cautions that haze could reduce visibility in parts of the Valley early Friday.
Halloween Could Turn Into A Trick-Or-Soaker
Saturday will be cloudy and cooler, with a high near 67 degrees and rain developing Saturday afternoon or later. Showers and thunderstorms are expected Saturday evening, followed by rain overnight, with a 70% daytime precipitation chance and an 80% chance Saturday night. New rainfall could total between a quarter-inch and half-inch overnight, making some Halloween plans a damp proposition.
The timing is a sharper update than Hoodline's Thursday forecast, which had rain developing mainly late Saturday into early Sunday. Fresno residents may get a dry start for trick-or-treating, but umbrellas and water-resistant costumes could become useful as the evening progresses.
Sierra Snow Adds A Bigger Mountain Concern
A Winter Weather Advisory has been issued for higher elevations in the Sierra Nevada from 8 a.m. Saturday through 7 a.m. Sunday. The forecast calls for a chance of several inches of snow above 7,000 feet, with substantially higher totals possible above 9,000 feet, so mountain travelers should expect more serious winter conditions than those in the Valley.
Rain Continues Sunday
Rain is expected to continue Sunday, with the heaviest precipitation falling later in the day and a high near 66 degrees. Northwest winds will increase to 5 to 10 mph, with gusts up to 20 mph. Skies should be mostly clear Sunday night, with temperatures falling to around 48.
Monday and Tuesday look calmer and mostly sunny, with highs near 68 and 70 degrees. Longer-range outlooks call for near-normal precipitation.
