Hydrometeorological Discussion National Weather Service / California Nevada RFC / Sacramento CA 1255 PM PST Thu Jan 22 2026 ...SCATTERED SHOWERS OVER CNTRL/SRN CA TODAY/FRI AS A LOW MOVES BY OFFSHORE AND OVER NV FRI AS A TROUGH DROPS IN... ...DRY CONDITIONS RETURN LATER SAT THROUGH EARLY NEXT WEEK AS HIGH PRESSURE BUILDS OFFSHORE, NEXT POTENTIAL SYSTEM MID-WEEK... .METEOROLOGICAL CONDITIONS (THU PM - WED AM)... An upper low continues to travel to the south offshore of srn CA this afternoon. Radar shows areas of precip rotating into srn CA near Orange County inland and northward over the Big Sur coast this afternoon. Observations since this morning report amounts generally less than 0.10" with a couple isolated areas just over 0.10". Forecast overall remains on track for showers to continue through tomorrow across srn CA as the low passes diminishing into Saturday as it moves inland over Baja. A trough descending into NV and eastern CA may produce a few showers over NV into Saturday before dry conditions return the rest of this weekend thanks to building high pressure over the eastern Pacific. Models continue to predict a frontal system arriving mid next week but disagreements remain on the general structure and timing. A wide range of solutions exists in the model ensembles, but most agree on at least some precip over nrn CA late Tuesday/Wednesday. Most of this precip looks to fall after the current forecast window. Therefore, minimal changes to the afternoon QPF though amounts went down a bit over srn CA over the next couple of days. Expecting 0.10" or less in general from both systems with isolated areas up to 0.25". |
