As we wait for our next round of widespread rain - we'll manage some sunny skies with a few scattered showers at times for today and highs only in the mid 50s. Expect rain to fill in again later tonight into the first half of Tuesday from a very chilly system moving down the coast. Snow levels may dip to near 2,000-2,500 in spots around the North Bay early Tuesday morning.Some very cold, dry air will filter in behind this system that will set the stage for some frosty and possibly icy starts to the mornings around midweek.A key factor in just how cold things get is if the winds back off enough on Wednesday morning. More wind = slightly more mild temperatures (think upper 30s to 40s instead of 20s and 30s). Its a good bet we'll at least see some frost/freeze advisories Wednesday and Thursday mornings. This could cause some issues for the getaway travel drive/fly on Wednesday morning. Use caution driving before 9am as temps will certainly be cold enough to support some patchy ice in spots. Our overnight temps should trend a bit more mild as more clouds return heading into the weekend with our next chance of rain looks to arrive around Saturday.- Rob Mayeda
But according to NBC Bay Area meteorologist Rob Mayeda we should keep those hatches battened in preparation of what's still to come.
He calls the system headed our way "Air Canada." Mayeda says a pool of continental polar air will spill down the California coast early Tuesday bringing a system that is already dropping snow all over the Puget Sound area of Seattle. The air mass should warm slightly by the time it reaches us - but it will be enough to support another round of low snow levels and the possibility of record breaking cold temperatures.
The forecast dips to the 30s for Wednesday and even lower in to the 20s on Thanksgiving.
Of course this will have an impact on travel. As you go over the river and through the woods, watch out for icy patches. It is also cold enough that Bay Area airports may be forced to break out the de-icing machines, which will slow air travel.
