Widespread, potentially high-end critical fire-weather concerns are expected to develop early in the week as an upper low and strong easterly mid-level flow develop off the Pacific Coast. ...Southern CA... Periods of moderate offshore winds over much of southern CA are forecast to gradually weaken late this weekend and heading into the new work week. However, this reprieve will be short lived, as a large upper trough and strong mid-level flow intensify off the Pacific Coast. By midday D3/Monday, high pressure over the Great Basin will strengthen as the upper trough over the Pacific cuts off. Some model uncertainty remains regarding the evolution of the cutoff low and the associated belt of stronger easterly flow. While various solutions keep the stronger flow aloft north of the LA Basin, enough upper-air support will likely be in place along with the strong low-level offshore gradients. Downslope winds and low humidity should begin to rebound late D3/Monday afternoon and steadily intensify overnight into D4/Tuesday. This will set the stage for another period of dangerous and potentially high-end critical fire-weather conditions across the LA Basin and southern CA Mountains. Offshore winds are expected to continue intensifying into early D4/Tuesday as offshore gradients peak around 8-10 mb. In combination with 35-50 kt easterly flow aloft, very strong gusts of 45-70+ mph are expected in the higher terrain. Multiple preceding days of poor humidity recovery will exacerbate the already very dry air mass. Single digit RH values are expected coincident with the strong winds. Critical fire-weather conditions are likely, with the potential for higher-end critical conditions across parts of the western LA Basin and mountains of southern CA D4/Tuesday. Strong winds should continue into D5/Wed before the upper low gradually moves offshore and winds aloft become more southeasterly. This shift should favor less alignment with terrain-favored corridors. Still, localized elevated to near-critical conditions may persist across the western LA Basin and Santa Barbra mountains as late as D6/Thursday. ..Lyons.. 01/11/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
