NWS Local Northern CA. Outlook Discussion
000 FXUS66 KSTO 282027 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 127 PM PDT Thu Mar 28 2024 .Synopsis... Periods of moderate to heavy mountain snow, rain showers, breezy southerly winds, and isolated thunderstorms will be possible into the weekend. Dry weather and a return to near to above normal temperatures is then anticipated early to mid next week. && .Discussion... Afternoon radar imagery shows shower activity across portions of the northern Sacramento Valley, Coastal Range, and the northern Sierra. Light snowfall accumulations are expected the rest of today with snow levels 3500-4500 ft and minimal impacts. HREF depicts the potential for isolated thunderstorms (10-20% probability) across portions of the Sacramento Valley and foothills from I-80 northward this afternoon and evening. Main storm threats include brief heavy rain, small hail, lightning, and gusty winds. Ensembles and clusters show an upper level low deepening along the West Coast through the end of the week and into the weekend. This system will bring breezy winds, widespread rain, and moderate to heavy mountain snow Friday into Saturday. WPC guidance indicates 0.5-1" of precipitation in the Valley and foothills and 0.50-1.5+" over the mountains through early Sunday morning. In addition, gusty southerly winds develop Friday afternoon and evening, generally along I-80 southward. The National Blend of Models (NBM) indicates a 50-70% probability of southerly wind gusts of at least 35 mph. Wind gusts up to 30-35 mph will be possible. Snow levels will range from 3500 to 4500 ft with this system. NBM depicts a 30-65% probability of 12 inches of snow above 5000 ft Friday morning through Sunday morning. Heaviest snowfall, with rates up to 1 inch per hour at times, is expected to occur from I-80 southward Friday afternoon into Saturday afternoon. A Winter Storm Warning has been issued for the northern Sierra and southern Cascades for elevations above 4000 feet from Friday morning through Sunday afternoon, and for the Coastal Range from Friday morning through Saturday afternoon above 4000 feet. Moderate to heavy mountain snow is expected during this time period, with snow totals from 4 to 8 inches above 4000 feet, 8 to 20 inches above 5000 feet, and up to 30 inches at the peaks. As a result, holiday mountain travel impacts are anticipated with periods of snow covered roads, travel delays, and chain controls. The NBM projects a 20-30% probability of thunderstorm development Saturday afternoon and evening, primarily across foothills and Valley locations from I-80 southward. Small hail, lightning, brief heavy rain and gusty winds are possible with any thunderstorms that develop. Lingering light showers are anticipated on Sunday, mainly over the Sierra foothills and mountains with little to no impacts. Otherwise, dry conditions are expected with afternoon high temperatures rising into the mid 60s in the Valley. && .EXTENDED DISCUSSION (Monday THROUGH Thursday)... Dry and warm weather expected over the area as upper level ridging develops in the PacNW. Above normal temperatures are anticipated Monday through Wednesday, with areas in the northern Sacramento Valley approaching 80 for afternoon high temperatures. As we move throughout Wednesday, ridging is expected to break down and move off towards the east as a deepening shortwave trough approaches the area Wednesday night and into Thursday. There is disagreement amongst Clusters regarding the timing of when the shortwave trough will impact the area, but there is agreement of a pattern change near the end of the extended period. The National Blend of Models (NBM) suggests precipitation chances return Thursday in far northern Shasta and Lassen Counties, then spreading mainly over the Sierra as we move through the day. && .AVIATION... Locally MVFR/IFR possible from showers the next 24 hours, otherwise mostly VFR conditions prevail. Isolated thunderstorms will be possible through the afternoon/evening hours, mainly at the northern Sac Valley sites. Surface winds up to 20 knots until 03Z Friday, then lowering to below 12 knots. In foothills/mountains, local surface wind gusts of 35 knots or more over higher terrains, snow levels remain around 3500-4500 feet. && .STO WATCHES/WARNINGS/ADVISORIES... Winter Storm Warning from 8 AM Friday to 5 PM PDT Saturday for Mountains Southwestern Shasta County to Western Colusa County- Shasta Lake Area / Northern Shasta County. Winter Storm Warning from 8 AM Friday to 5 PM PDT Sunday for West Slope Northern Sierra Nevada-Western Plumas County/Lassen Park. && $$
