ANOTHER DENSE FOG EPISODE WEDNESDAY MORNING
Visibility was reduced to 200-400 feet at the height of Tuesday morning's commute in the South Valley. Moist air that was laid down by rains last week is still solidly in place. Fog will be a daily threat until the atmosphere changes and winds come along with the new air mass. That will occur on Friday. But until then, a Dense Fog Alert runs on Wednesday from 3 AM to 11 AM in the South Valley. Looks for hazardously low visibilities to once again plague motorists. Please drive slowly and cautiously when encountering areas of dense fog. Although there were no school delays on Tuesday in Kern County, that may not be the case on Wednesday.
A cold front will blow through Kern County from the northwest on Friday morning. Look for rain to develop with .05" to .20" expected. That estimate is slightly lower than yesterday's appraisal. Models have been trending a touch drier with moisture holding more to our north. A nice rainfall is still expected. Some clearing will take place Friday afternoon, but pile-up clouds should re-fill the South Valley Friday evening. Winds will pick up in the mountains with gusts to about 60 MPH in the usual spots. Snow levels are forecast to fall to about passes level by late Friday evening. I have a 60% chance for rain transitioning into snow showers down to 3,000' by early Saturday morning. So there could be issues with travel over the major passes on Saturday morning. At this time 2-3" is possible above 5,000', but a trace to 1" is expected at 4,000'.
Following a break Saturday afternoon through Sunday, the American model is depicting a fast moving wave pushing across northern California that could bring some rain on Monday. The European model is showing a building ridge in the eastern Pacific that cuts off progressive weather systems. However, I am currently discounting the European solution in favor of the American model which has shown run-to-run consistency. According to the American guidance, yet another weather system should pull into California by the following Thursday. This appears to be a wet pattern with rain chances coming along every 2-3 days. Hopefully, this pattern will continue into February.
