...Potential For Critical Fire Weather Conditions Starting Early Friday...
...Dry and Warm Offshore Wind Event Possible Thursday Evening Through Saturday...
A large low pressure system will move across the Pacific Northwest on Wednesday and into the central Rockies by Thursday. This "inside slider" will likely bring increasing offshore winds to southern California late Thursday through Saturday. North winds (Sundowner winds) will first develop across the Santa Ynez Mountains of Santa Barbara County Thursday afternoon into Thursday night. Then, northeast winds (Santa Ana winds) will develop across the Ventura and Los Angeles County by early Friday morning, continuing into Saturday. Very dry air is likely to accompany the onset of the gusty winds with many areas experiencing relative humidity less than 10 percent on Friday and Saturday. In addition, temperatures on these days will rise above normal from the foothills to the beaches of Ventura and Los Angeles Counties. At this time, winds are expected to weaken and turn back onshore on Sunday, which would also lead to slightly cooler temperatures and slowly increasing humidity.
TIMING AND FORECAST CONFIDENCE
There has been a trend of consistent computer model data to give us moderate confidence of the potential impacts and timing. The details on the overall strength and duration of the winds on Friday and Saturday are less certain at this time. However, this event looks drier and windier than what occurred last week.
