Western heat wave to continue this weekend

The extreme high temps for California and Arizona that started Wednesday will continue through Sunday. Temps this week in the San Joaquin Valley are averaging 17 degrees above normal for these dates.weat

Many crops in the valley are coming on line, and this heat will speed up the process. Cherries, blueberries, stone fruit and veg, including broccoli, are new crops that should all benefit from the heat.

The cold winter in California provided a great number of chilling hours, and the tree and bush crops should be bursting at the seams with fruit this year.

Bakersfield at the southern end of the valley had a high yesterday of 97 while today and tomorrow will be 95 and 92 on Sunday. Fresno in the middle of the valley saw a high of 96 yesterday and 95 today. Weekend highs will be in the low 90s but by Monday temps will drop down to the low 80s. Modesto in the north of the valley had a high of 93 yesterday and will be 91 today and tomorrow.

In the desert region of Coachella, high temps yesterday and today are 103 and will be 101 tomorrow and 97 on Sunday. Look for volumes of Bell peppers to come on strong along with the other spring crops such as eggplant and tomatoes.

These temps should also be good for the upcoming melon crops out of the desert regions of California and Arizona.

Crops that are at the end of the season will most likely be negatively affected. Citrus in the San Joaquin Valley for example will probably be stressed by these temps. Fruit still on the trees for this season's crop could be affected and also might see some bloom drop for next season’s crop.

Another unintended consequence is the rapid melting of snow in the Sierra Nevada mountains that line the east side of the San Joaquin Valley. Certain rivers that flow from the mountains can expect flooding.

Georgia will be in the mid 80s to low 90s the next 10 days with a chance of a light shower today. Florida will experience the same temps with a greater chance of rain today, up to 0.35 inches in certain regions of the state.

Blueberries, peaches and melons are the newest crops coming from these regions. The spring/summer crop of tomatoes out of norther Florida and southern Georgia is just around the corner.
