Hydrometeorological Discussion National Weather Service / California Nevada RFC / Sacramento CA 800 AM PDT Thu Apr 2 2026 ...LINGERING SHOWERS THIS MORNING AS A LOW PASSES TO THE NORTH... ...RETURN OF DRY CONDITIONS AND ABOVE NORMAL TEMPS FRIDAY THROUGH EARLY NEXT WEEK... .METEOROLOGICAL CONDITIONS (THU AM - WED AM)... Precip continued across much of nrn and central CA overnight, mainly along the coast and over the mountains. Observations report 0.50- 1.50" across the northern/central Sierra and 0.25" to just under an inch along the coast from Monterey northward. Lingering showers this morning as a low continues to traverse the PacNW with the southern edge scraping the northern regional border as it passes. Amounts look relatively light at 0.10" or less for most areas, though up to 0.40" for the srn OR Cascades and over 0.50" for the Ruby mountains in ne NV. Precip will diminish this afternoon with showers shifting to ne NV as the low moves through ID and into WY by the evening. Behind the low, ridging will re-build over the eastern Pacific returning dry conditions for the rest of the week and through the weekend. This will also return above normal afternoon high temperatures with anomalies around +5 to +15 or so deg F through at least Monday. Models then show another low approaching the west coast Tuesday/Wednesday. There is some uncertainty as models disagree on the path and timing of this next system. There is at least some chance of showers along the nrn CA coast into Wednesday morning. The official forecast keeps this at less than 0.10" for most areas, but ensemble spread at Arcata is anywhere from 0" to 1.25". Freezing levels today 4-8 kft north of I-80 rising tonight back up to 8-11.5 kft for most of the Sierra. Higher freezing levels (10.5+ kft) the rest of the week as high pressure returns. This may lower some into Wednesday, but uncertainty as it depends on how close the low is to the coast at that time. For now expect generally 10-12.5 kft across the region once the current system passes. Please Note: This product may NOT be routinely updated.
