If the above-normal mid-80s temperatures have gotten you ready to trade your flannel bedsheets for cotton, you might want to hold off for a few days.

The National Weather Service is predicting lows in the upper 40s and a below-normal high of 64 degrees on Saturday.

The normal high temperature for this time of year in Fresno is 75 degrees, NWS Hanford meteorologist Carlos Molina said Wednesday.

Rainy weather arriving late Friday and continuing into Saturday could bring a few hundredths of an inch of rain to the Valley — enough to wet but not soak the ground — a quarter-inch to a half-inch of rain at lower Central Sierra elevations, and a couple inches of snow above 6,000 feet, Molina said.

Cool Now, Hot Later

A weak disturbance over Northern California is allowing cooler air from the coast to push inland over Central California, lowering the highs in Fresno this week. The weekend’s weather will be the result of a stronger disturbance that’s pushing southward, Molina said.

Typically such storms at this time of year track toward the Pacific Northwest and Northern California, he said.

The highs will gradually warm up next week. May 1 could be Fresno’s first 90-degree day in 2025, followed by cooler weather for a week or two, Molina said.

“Hopefully, we can hold off on reaching 100 until closer to June,” he said.

The record for the earliest day of 90-degree weather in Fresno was March 15, 2015, Molina said.

Here are the highs and lows for Fresno for the next eight days: Wednesday, a high of 81, low of 49; Thursday, high of 76, low of 50; Friday, high of 69, low of 48; Saturday, high of 64, low of 47; Sunday, high of 70, low of 50; Monday, high of 76, low of 53; Tuesday, high of 82, low of 58; and April 30, high of 86, low of 58.
