Rain Coming to Pasadena to Close Out 2022

After a sunny Christmas weekend, Pasadena looks to be in for days of rain to close out 2022. 

The National Weather Service’s forecast issued early today covers the period through New Year’s Day —  but does not forecast weather for ‘Rose Parade Day,’ which this year is Monday, Jan. 2 (reflecting the Tournament of Roses ‘Never on a Sunday’ rule).

The current forecast call for a chance of rain in Los Angeles County for five straight days beginning Tuesday and continuing through New Year’s Eve, likely followed by sunshine on New Year’s Day and then three more days of possible rain.

According to the National Weather Service, rain is likely to fall across Los Angeles County on Tuesday night, with snowfall likely in the mountains by Wednesday night. A chance of rain is in the forecast every day through Saturday.

The NWS said between a half-inch and 1.5 inches of rain were expected in Los Angeles County in the initial band of precipitation.

The system will begin dumping rain over San Luis Obispo and Santa Barbara counties late Monday.

The weather service noted that the timing of the systems later in the week is “problematic and will probably need adjustments with later forecasts.”

“Uncertainty grows from there, as ensemble solutions diverge in the track and depth of the short wave that follows for Thursday, and the additional waves later in the week, into New Year’s Day,” the agency stated.

No winter weather advisories have yet been issued for the region.

Temperatures will also return to winter-like levels this week after a warm spell, dropping from a projected high of 76 degrees in Pasadena on Monday to 63 Tuesday and Wednesday and 60 on Thursday, according to the NWS.

Overnight lows will mostly be in the upper 40s and lower 50s.
