Hoodline’s forecast points to a wetter Wednesday in Fresno. Monday is expected to be sunny and warm, with a high near 82 degrees.
Rain Timing and Expected Amounts
Monday will be the last warm, dry day for a while, with a high near 82. Monday night will be partly cloudy, with temperatures falling to about 54 degrees.
An earlier Hoodline forecast put Tuesday’s high near 82, with a 30% chance of rain, and pointed to a midweek shift toward rain. The National Weather Service defines a rain-chance percentage as the probability of at least 0.01 inches at a particular forecast point during the stated period, not as a rainfall amount, according to the National Weather Service.
A Wetter Wednesday
Hoodline forecast a 70% to 80% chance of at least 0.10 inches of rain through Thursday morning.
How the Rain Compares With Fresno’s Annual Norm
The 0.10-inch threshold for the forecast’s 70% to 80% chance of rain is roughly 1% of Fresno’s annual precipitation norm of 11.50 inches, according to the National Weather Service Hanford’s Fresno precipitation table. That annual figure provides a long-term benchmark for the rain expected this week.
Putting Fresno’s Rain Forecast in October Context
The same National Weather Service Hanford precipitation table lists Fresno’s October normal as 0.63 inches. The 0.10-inch threshold for the forecast’s 70% to 80% chance of rain is about 16% of that monthly benchmark. As a separate historical comparison, the National Weather Service Hanford’s Fresno October records list 1.46 inches as the October 1 precipitation record, set in 1976—well above the 0.10-inch threshold for this midweek system.
Wednesday night should remain wet and cool, with another 70% chance of rain. Some higher-elevation roads in the Sierra could also become slick as the broader storm system moves through, even though no watches, warnings or advisories are posted for Fresno in the current forecast.
Dryer Weather Returns For The Weekend
Thursday could bring a shower before partly sunny skies and a high near 68. Friday should be mostly sunny near 70.
Sunday is forecast to be warmer than Monday, with a high near 88 versus about 81; Monday should still be warm for outdoor plans. Rain gear and a backup plan may be useful for activities Tuesday night or Wednesday; the forecast currently points to a brief wet spell, with drier weather returning later in the week.
