Hydrometeorological Discussion National Weather Service / California Nevada RFC / Sacramento CA 830 AM PDT Mon Mar 23 2026 ...CONTINUED HOT AND DRY WEATHER UNDER RESILIENT RIDGE... ...POTENTIAL FOR WEAK SHOWER ACTIVITY OVER NORTH COAST ON TUE/WED WITH WEAKENING FRONTAL PASSAGE... .METEOROLOGICAL CONDITIONS (MON AM - SUN AM)... No changes to the afternoon forecast with ridging keeping the area warm and dry. Only chance for precipitation remains on Tuesday and Wednesday morning when the ridge is forecast to flatten slightly allowing for a weak frontal passage into the far north coast of California. Southwesterly onshore moisture flux ahead of the front will remain relatively weak (IVT <500 units) and will mostly dissipate below 250 units south of Cape Mendocino. This weak frontal passage will increase the potential for light shower activity on Tuesday into early Wednesday. Accumulations are forecast to be relatively light with up to 0.3 inches over the Smith Basin. Looking beyond the 6-day window, guidance currently suggestS the potential for a wetter pattern during the first week of April, though uncertainty will remain high until lead times fall within the 6-day window. The CPC currently has a 33-40% chance of above normal precipitation in their 8-14 day window (Valid 30 March to 5 April). Please Note: This product may NOT be routinely updated.
