While the average last freeze/frost along and north of Highway 8 is typically around this time of year, the last frost on average farther south in the region is usually in the first half of May. Being that the calendar shows we are one to two weeks past this point in the month, and the growing season is in full swing across the area, this frost could have notable impacts on temperature-sensitive plants.

Mostly clear to clear and unseasonably chilly conditions are forecast for Sunday night into Monday morning with relatively light winds, which tend to be ideal conditions for tumbling temperatures and in case of the development of frost. If you have plants outside, either cover them up Sunday evening through Monday morning, or if they are potted plants, bring them indoors for the night.

Milder conditions are on the way in the days ahead with lows in the 40s while highs will be rebounding into the 60s to the 70s later in the new week.
