...Southern California... Elevated to locally critical fire weather threat will continue for portions of southern CA through today. Current surface observations show accelerating east-northeast winds in response to an amplifying offshore pressure gradient with a 1036 mb surface high pressure situated over the Northern Rockies. Rapid drying over the last 12 hours has resulted in relative humidity falling below 15% in some locations, collocated with east-northeast winds of 15-25 mph, with gusts of 35-45 mph. Elevated highlights were removed for southern Sierra Nevada as less robust winds and slightly higher relative humidity will limit a broader fire weather threat. Poor relative humidity recoveries heading into tonight are expected as well with the continued offshore flow, particularly where winds remain elevated along adjacent mountain ranges of the L.A. Basin.

...Synopsis... An upper-level trough will intensify as it digs into the lower Mississippi Valley. In the West, an upper ridge will move into the Great Basin. At the surface, an expansive surface high will shift eastward with time. Breezy conditions will exists behind a cold front surging through the southern Plains.
...Southern California... Fire weather concerns will be focused across the typical wind-prone areas of LA/Ventura Counties and vicinity. The offshore gradient will be strongest during the morning and very gradually taper off in intensity into Wednesday. Winds of 15-25 mph appear possible along with RH in the 15-20% range. Local fuel information has suggested that fuels will support fire spread. Elevated to possibly brief and localized critical fire weather can be expected.
...Southern High Plains... Dry and breezy northerly winds will persist across the region behind the cold front. Given the current state of fuels, sustained fire weather concerns are not expected, but locally elevated concerns could develop.
