Hydrometeorological Discussion National Weather Service / California-Nevada RFC / Sacramento CA 630 AM PDT Tue Aug 25 2026 ...CHANCES OF SHOWERS/T-STORMS IN THE AFT/EVE THROUGH MOST OF THE PERIOD, MAINLY SE CA, THE SIERRA, AND NV... ...ABOVE NORMAL TEMPERATURES FOR MUCH OF CA/NV THE NEXT FEW DAYS WITH MORE WIDESPREAD NEAR TO BELOW NORMAL CONDITIONS FRI ONWARD... .METEOROLOGICAL CONDITIONS (TUE AM - MON AM)... The pattern remains the same with a strong area of high pressure over the Four Corners/TX and troughing offshore of BC/PacNW/nrn CA. Areas closest to the trough are expected to see near to below normal temperatures the next few days while most of NV and central/srn CA experience above normal temperatures (+5 to +15 deg F). By Friday, the offshore trough looks to move inland into BC and the PacNW while additional troughing expands southward offshore. This should push relatively cooler temperatures further across the region for Friday bringing more widespread near normal conditions the rest of the period. The other impact of the continued presence of the inland high pressure will be mid level moisture and instability rotating into the area throughout the forecast period. The exact locations best expected to see scattered showers and thunderstorms will fluctuate daily, but generally over se CA, parts of the Sierra, and NV particularly in the afternoons and evenings.
