Hurricane forming, heat hitting California and Michigan

Starting this Thursday extreme high temps are expected to hit California, which could affect quality of many commodities. 

In the southern deserts where grapes are still being harvested, look for a high of 115 on Thursday and 118 on Friday. Saturday through next Tuesday will experience a high of 116. Low temps will remain extremely warm during these six days -- around 87.weat

The San Joaquin Valley will also see warmer temps starting Thursday with highs to reach 106 by Saturday. These warmer temps will last through Tuesday, July 16. Low temps during this spell will be in the mid-70s. 

The Salinas Valley won’t be able to escape the heat. The city of Soledad will see max temps well above 90 tomorrow through next Monday. The hottest day will be Saturday with a max temp of 100. Quality could be an issue with lettuce and other wet veg coming from this area. 

This kind of extreme heat is tough on plants as well as the fruit. We might see an increase of production over the next week or so but be careful of quality issues. It not only affects the fruit ready for harvest but can also be detrimental to the plant and future fruit growth. Could affect markets in the longer term. Might want to plan ahead this week when buying.

Tropical depression likely to form bringing heavy rain to Gulf Coast states
There is a high possibility of a hurricane forming over the next five days. “A trough of low pressure located over central Georgia is forecast to move southward toward the northeastern Gulf of Mexico, where a broad area of low pressure is expected to form on Wednesday," according to the National Hurricane Service.

Environmental and ocean conditions are forecast to be conducive for development and a tropical depression is likely to form by the end of the week while the low moves slowly westward over northern Gulf of Mexico. Regardless of development, this system has the potential to produce heavy rainfall along portions of the northern and eastern U.S. gulf coast later this week.

High temperatures return to Michigan early next week
Last week Michigan had a reprieve from the extended high temps it experienced late last month, but things will change soon. Tomorrow will once again see a high temp of 90 before cooling off on Wednesday, but come Sunday max temps will reach into the 90s where they will remain until at least Wednesday, July 17. 

There is also little or no chance of rain over the next 10 days. Look for possible quality issues on product from these regions.
