If there has been a model trend this year - it has been to make monstrous storms that tease us and then fade into the sunset.
Thursday's system will have little to no impact on us, mainly because of the system that's coming through Monday night/Tuesday. It's forcing Thursday's system to move off to sea rather than ride up the eastern seaboard.
Before we get to Thursday, we have our system for tonight into Tuesday. This cold front has a good deal of cold air behind it and that's what will cool us down Tuesday, even though we don't see a lot of precipitation with it. Higher elevations to the west will likely see some snow along with upslope snow showers, while the Valley may have an isolated rain/snow shower move through after midnight. No accumulation is expected, in the Valley - although a quick coating closer to the mountainsides can not be ruled out.
Some snow showers may brush the southernmost areas of the Valley Thursday morning, but most of the moisture and precipitation will stay to our south and east.
After Thursday's system, we'll actually see a significant pattern change. Remember when we're cold, the west coast is usually warm. We're under a trough and they're under a ridge(usually). Well, that's going to switch up from this weekend through to (probably) the last week or so of February. This doesn't mean it will be constant warmth, as systems will still come through with colder pockets of air, but the overall pattern will be warmer with an eastern/central US ridge and a western US trough. Areas in the west may see the longest stretch of cold air they've seen all winter as things finally switch up and actually become more "La Nina".
