Today (Saturday): A backdoor (that pushed in from the east and northeast) cold front brings us a bit of a marine air mass today. That means low clouds and even some fog are possible, particularly in the morning. Despite low sun energy this time of year, the oceanic flow is not very strong, with east winds around 5 mph. Given only light moisture transport, we should still break out into the sun without too much problem. High clouds may also be drifting overhead at times though, which may limit full sunshine. Temperature peaks should range from near 50 to the mid-50s, close or just above normal for December 1. Confidence: Medium
Tonight: The flow off the ocean is relaxing further, though there may still be enough moisture in the air to give us some cloudy periods. I don’t think we’ll end up socked in, so let’s call it partly clear. Lows might make the mid-30s in the coldest spots, but probably more like the low 40s downtown. Winds are light from the east and southeast. Confidence: Medium-High

Tomorrow (Sunday): Warmer air becomes more strongly entrenched with winds heading into a southerly direction. We may still have some clouds around, particularly early and then again around sunset, but the day should end up at least partly cloudy. Compared to today, it’s atypical weather for December as highs reach the upper 50s and low 60s. Confidence: Medium-High
Tomorrow night: Clouds drift by at times as a little upper disturbance passes by to the north, leaving us partly to mostly cloudy for the night. Those clouds, along with a wind from the south and southwest, help keep readings up. It’s not out of the question we get a quick shower or two across the area either, so a 10-20% chance of a sprinkle centered around midnight seems prudent. It’s not too chilled as temperatures only dip toward the mid-40s in the suburbs and near 50 downtown. Confidence: Medium-High
Monday is looking rather delightful, unless you’re looking for some wintry weather. Other than a few clouds, probably mainly high level, it’s going to be quite sunny. With high pressure largely in control in an increasingly mild air mass, highs should head into the mid-60s most spots. Sundown brings an offer of another mild one and lows are similar to Sunday night, mainly in the mid-40s to near 50. Confidence: Medium-High
On Tuesday, a westerly flow aloft and at the surface should promote plenty of sun and warmth. As is often the case out ahead of the front, we might get a little extra warming, so highs from the mid-60s to near 70 seem a good bet. Enjoy, as more seasonal conditions are right behind with cooler air inbound overnight or into Wednesday. Confidence: Medium
