If you caught the daybreak or noon show Wednesday, you probably heard me talk about a silly type of front. Usually it's just a "cold" front - but Wednesday we talked about an "anafront".
The terms katafront and anafront are typically used in the context of a cold front. An anafront usually has the majority of the precipitation behind the actual boundary, leaving an area with clouds and rain for 12-18 hours after the front has passed. A katafront is what we typically think of with a cold front - some showers and/or thunderstorms ahead of the front, but after it passes, we clear out quickly.
Cooler air has settled in (for a day), but it will quickly be replaced by warmer, more moist air by Friday morning. Two disturbances will affect us this weekend, one from Friday afternoon through Friday night, and the second moves in Saturday evening through Sunday morning. However, with both of these disturbances, temperatures will stay at or just slightly above 70 degrees.
If you're looking to make outdoor plans for Mother's Day - the later in the day, the better. I would keep a rainy day plan just in case, but a late afternoon lunch / early dinner should be fine outdoors.
Heat returns for the middle of next week, along with the chances of showers and thunderstorms throughout the Valley.
