The National Weather Service in Sacramento has provided an updated forecast indicating the cooling trend throughout the region is set to continue through the next week. As we bid adieu to the heat, a featherlight weather disturbance is expected to graze across our skies later tonight into tomorrow, ushering in light rain primarily north of the Interstate 80 corridor. For those longing for reprieve from California's persistent swelter, below to near normal temperatures are here to stay a while longer.
As the shortwave trough inches closer, we've noted a discernable chill in the pre-dawn air, which is "2 to 8 degrees cooler than the same time yesterday morning," as reported by the National Weather Service. An afternoon bask in the Valley or Delta today will be notably cooler with breezes expected to gust around 15 mph, tempering the day's climbing digits to a comfortable low to mid 80s, with the foothills hovering in the comfortable upper 70s to low 80s. Relief comes in the form of these gentle winds, a subtle herald of the season's shift.
Northern California's precipitative intermission will be brief, with the National Weather Service predicting a "light precipitation" curtain call beginning late tonight. The anticipation of rainfall has shifted slightly, as accumulations have been adjusted downward, now ranging between a slight 0.05 and a moderate 0.20 inches. Tomorrow's showers peak in the morning, offering a natural interlude before clearing in the afternoon, paving the way for a reprise of sunnier skies come early evening.
The forthcoming week seasons NorCal with a patchwork of weather patterns. An upper trough expected Tuesday should move through by Wednesday, bringing "widespread rain" to the region and hinting at some late snowfall on the higher peaks as snow levels drop post precipitation, according to the NWS discussion. The latter half of the week promises drier conditions as a ridge builds, yet temperatures should remain the side of temperate, while gusty northerly to easterly winds might sweep through Thursday and Friday, adding an invigorating bite to the air.
The NWS also mentions VFR conditions for interior Northern California, with localized MVFR in the vicinity of the Shoe Fire in Shasta County. Aviation interests should note potential late-night visibility reductions north of a line from KUKI to KCIC due to the expected precipitation post 09z tomorrow. For the most part, surface winds will stay at bay, not exceeding 12 knots, save for southwest gusts reaching 15-20 knots near the Delta. Into the higher terrain, southerly surface wind gusts could reach up to 30 knots later on Friday, adding a layer of complexity for airborne travelers.
No official watches or warnings have been issued as of yet, ensuring a relatively mild meteorological passage through the weekend and into the next week. For continued updates, visit the National Weather Service website.
