A frost advisory (temperatures 33 to 36 degrees) and freeze warnings (temperatures 28 to 32 degrees) are in effect through 8:00 AM PDT this morning. The cold conditions could kill crops, other sensitive vegetation. Take steps now to protect tender plants from the cold. If you have animals, take steps and precautions to help from the cold.
Temperatures begin to trend warmer today with highs this afternoon warming back into the 70s, with lows tonight back up into the 40s.
High temperatures will be increasing during the upcoming week. Looking at July 3 (left image) and July 4 (right image), the probability of seeing highs > 90F is confined to a few valley locations. However, the area expands greatly for July 4th and many in the valley areas will more than likely see these warm high temperatures.
Look for morning low temperatures start out cold this week, but warming several degrees each morning back into the 40s and 50s by the end of the week. Afternoon high temperatures will also be below normal but will warm back into the 80s and 90s by the upcoming weekend.
Temperatures plunged well below normal on Sunday, even bringing a dusting of snow to some of the higher mountain peaks, including the Rubies, as seen here. Over at the Eureka airport, the chilly weather made history by hitting a record low of 30 degrees for June 28th, tying the previous record set back in 1996.
