...Hot...dry and breezy weather with elevated fire danger across southwest California late Wednesday through early next week...
An upper level ridge of high pressure will begin to build over the West Coast on Wednesday...bringing a significant warming and drying trend to southwest California through early next week. In addition...weak to moderate offshore winds are expected to develop over the Los Angeles and Ventura County mountains and valleys Wednesday into Thursday...and persist through Friday.
Afternoon high temperatures will rise into the 80s to mid 90s across the coast and valleys by Thursday...and to around 90 to the lower 100s by Friday. The heat is expected to peak on Saturday with valley highs around 105 degrees. Overnight lows are expected to remain rather warm...in the mid to upper 60s across the valleys. Offshore winds are expected to peak Thursday morning across Los Angeles and Ventura counties with northeast gusts up to 35 mph in the valleys and up to 45 mph in the mountains. A drying air mass is expected across all of southwest California with relative humidities falling into the lower teens by Thursday and into the single digits for locations away from the coast Friday through Sunday.
The combination of rising temperatures...low humidity and offshore winds in combination with critically dry vegetation will bring elevated fire danger to much of southwest California late Wednesday through early next week. The highest fire danger is expected to be across the Los Angeles and Ventura County mountains and valleys where the strongest northeast winds are likely to occur. (See laxrfwlox for details).
