Another cloud-filled, mixed-sky day as upper level moisture advances ahead of a weak upper level shortwave trough currently off the coast of Mendocino/Humboldt county. Current radar is picking up on some echos aloft, but there are not expected to make it to the ground as rain, especially the massive block of dry air in the mid-levels up to about 23 kft. One thing this might actually bring us that you'll want to pay attention to is a wonderful sunset this evening, if you're in an area without low clouds.

A couple more chilly nights ahead before another approaching shortwave trough promotes moist, southerly flow, which will bring temps up a few degrees for overnight lows and afternoon highs. This shortwave brings the only confident chance for measurable rain within the 7 day forecast, and amounts have been trending lower with each issuance. By late Tuesday, a 120 kt jet streak downstream of the trough axis becomes the driving force to lift the system towards the north. This likely thwarts any meaningful rain chances across much of our region. As of now, it looks like the North Bay counties are the only areas that would get anything worth mentioning (0.05-0.10"), and elsewhere may only see as much as a hundredth or two. Most of this looks to take place Wednesday morning. After that, ensemble cluster analysis exhibits high confidence that the rest of the week will remain dry. The next chance of rain doesn't enter the picture until the 1st of February where a deeper upper level trough may swing through the EPac, but uncertainty is high in N-S placement. As such, there is not much confidence in early Feb rain at this point.
