What relation does the dangerous SoCal weather pattern have to us?
In weather, what happens in your area can oftentimes be traced to something much bigger and much farther away. That is certainly the case with this sharp cool-down, as we can trace it back (indirectly) to the wildfires in southern California.
The Thomas Fire in Ventura County, CA is the most dangerous one currently, though there are many others being detected by satellite. (That's what you see plotted on the map below.) A tweet sent out on Wednesday afternoon by the Ventura County Fire Department (@VCFD) said that the fire has now burned 65,000 acres with 0% containment.
Why hasn't it been contained? The winds are a nightmare right now. As the winds come down the mountain and spill out into the canyons, the fire fans out of control.
That's why the Storm Prediction Center has much of Southern California in a 'Critical' to 'Extreme' fire danger, which are the two highest levels that the SPC issues.
So, how does this relate to us? Although November was exceptionally dry here, we don't see any fire risk quite like this. Instead, the system that's increasing the fire danger in California is helping send colder air down to us.
High pressure anchored over the western US is keeping things dry in California, but also forcing the winds down into the canyons to spread the fire. That same high pressure system is blocking an area of cold air into the eastern US for quite some time.
Does this colder air mean snow for us? It might, but no major winter storms look to impact the area. Be sure to check here for updates throughout the week.
