Late night runs, snow coming!

When you know it is going to be colder later in the day, you get your run in before work in the early morning hours.

We have a big dip in the polar jet stream and causing our cool weather for the days and even weeks ahead.  It is looking more and more likely that this pattern will set up for a lot of the winter.  Get ready for lots of clipper systems bringing rounds of light snow over and over. 

I cooked this graphic up yesterday showing the winds and the California wildfires. The smoke was even view-able from our weather satellites and especially NASA's Terra satellite.

The fire forecast today has a LOT of SoCal under the "extreme" criteria for wildfires today.  Not good.  Very strong winds and very low humidity are not a good combination fighting the fires.

If you thought yesterday was cold, brace yourself! We warmed into the 40s yesterday afternoon, but the rest of the extended forecast has highs in the 30s and 20s! A weak disturbance will kick through for the first half of today bringing a few flurries and spotty light snow with no accumulation expected. More sun Friday before more clouds start rolling back in later in the day.

Snow showers for midday and the afternoon on Saturday. The main track of this system is looking to go by our north, so our accumulations will be light, with up to 1" possible, and a few spots may see slightly more, mainly north. A few flurries possible Sunday and a high of only 30! Another winter system kicks in later Monday into Tuesday. Monday we will be warm enough that the leading edge may start as a brief wintry mix then transition over to snow showers late Monday and Tuesday. Accumulations look light for Tuesday, as well, with this system, but the final track will help determine snow total. Have a good one!

Best,
