A cool northwest wind ushered in colder than normal weather on Thursday, and it will stay around through the end of the workweek. The temperature will dip into the upper teens to low 20s by dawn on Friday as the wind relaxes in the overnight hours.
Friday will be partly to mostly sunny with a light northerly breeze in the morning turning onshore in the afternoon. Highs will be in the upper 30s. The temperature will fall into the upper 20s briefly Friday evening before slowly rising after midnight as cloud increase. Light snow, sleet, or rain is possible around dawn on Saturday. Any frozen precipitation will change to rain within an hour or two, and with minimal snow accumulation, on Saturday morning.
Rain is likely most of the day Saturday. Highs will be in the upper 30s to low 40s. There will not be enough rain for widespread flooding, but some big puddles are possible around ice-clogged storm drains. Rain showers will continue Saturday evening before a possible break in the action after midnight. The temperature will fall through the 30s at night, and rain or snow showers may develop by dawn on Sunday.
The precipitation does not look steady on Sunday, but there is a better chance of snow showers than rain showers. Even if the precipitation is exclusively snow, it will likely not accumulate during the day with temperatures in the low 30s. The snow shower threat ends Sunday night, and the start of the workweek will be cool and quiet on Monday. Highs will be in the 40s. A cold front will move through with rain and/or snow showers Tuesday morning before colder weather settles in for the midweek. Highs will be in the 30s.
