There are 2 totally predicable weather patterns here:
1. On January 1, it won't rain. Period. Even if it rains the day before and the day after, it won't rain on Jan 1.
2. Labor Day, it will feel like a furnace. You can count on it. No matter how nice and cool and comfortable it might have been the day/week before, it will be sweltering on Labor Day and the week the kids return to school. Except this year.
How true Yen...and don't forget December 25...you can count on Santa Ana winds.
