SLO County weather forecast for the week of June 30

Here is this week’s weather forecast by PG&E meteorologist John Lindsey.

However, the warm-up will be short-lived as a 1,006-millibar surface low pressure system moves over the Central Coast with North County and coastal valley temperatures decrease by 5 degrees Tuesday. This low-pressure system will also produce a persistent marine layer along the coastline with some of the beaches remaining mostly overcast throughout the day. The cooling trend will continue into Wednesday.

The area of low pressure responsible for persistent marine layer will move toward Nevada later Wednesday. This condition will produce increasing northwesterly winds and a greater amount of clearing along the coastline Thursday into Saturday.  

The marine low clouds are expected to roll in after Fourth of July fireworks shows. However, if they redevelop earlier than anticipated, the cloud ceiling should remain above 500 feet of altitude, which will allow for good viewing of the displays. 

It appears that temperatures across the North County will warm to above normal temperatures early next week. When temperatures are unusually high, avoid strenuous activities in hot, direct sunlight and drink plenty of water. Pay attention to your body. Muscle cramps, dizziness and nausea may be signs of a heat-related illness.
