The weekend: Warm Saturday, chill for Sunday, with a little rain in the middle
A warm front will continue to lift north across the area tonight, eroding a wedge of high pressure and setting us up for an unseasonably warm Saturday. We may start with some patches of fog during what will be a very mild morning, with lows only bottoming out around the mid to perhaps upper 50s. (The normal high for December 11 is 63°!) We’ll keep a mix of clouds and sun around as breezy southwest winds help pump in warmer air ahead of an advancing cold front. This will allow highs to top out in the mid-70s, 10°+ above normal.
Late Saturday into early Sunday morning, the aforementioned cold front will move through the area, bringing with it a weakening line of showers. It doesn’t look like we’re getting much in the way of rain out of this, so there are no real concerns as the line crosses the area. It should be out of here by daybreak Sunday (exact timing TBD), bringing a cooler airmass along with it. Highs will be right on the line for normal for December 12 on Sunday as clouds scour out, bringing us a sunny finish to the weekend.
Whatever rain we get overnight Saturday/early Sunday looks to be the only precipitation we’ll see for the next several days as our very La Niña-esque cool season rolls on. Enjoy the weekend!
