- Southern California - After an extended period of warm and dry weather, the second half of January will feature some cooler weather mixed with seasonably mild conditions. An occasional chance for a shower will pop up, but it will remain drier than average.
- Northern California - Finally some rain! This is great news for everyone in NorCal and the Pacific Northwest. There will be a parade of storm systems bringing periods of heavy rain for the last half of this month.
- East Coast - Mild weather will continue with a few chances for rain, which is always good news. However, it's bad news for snow lovers. Things could briefly change for early February, but don't hold your breath!
