Key Insights

  • High temperatures are expected to spike, reaching up to 10-15 degrees above average in some areas.
  • Increased humidity due to a cut-off low over Baja will create a tropical feel.
  • There is a slight chance of showers and thunderstorms, particularly in the mountains.
  • A trough of low pressure will bring cooler, drier air next week, dropping temperatures 5-10 degrees below average.
  • Coastal areas will see highs in the low 70s, while inland areas could reach the mid-90s on Friday.

In-Depth Analysis

San Diego County is bracing for a short heatwave characterized by temperatures significantly above average and unusually high humidity for the region. The combination of high pressure building over the area and a cut-off low pressure system pulling in tropical moisture from Baja California will lead to a brief "tropical" weather pattern. Friday and Saturday are expected to be the hottest days, with inland areas like Escondido and Ramona potentially reaching 95 degrees.

However, this heatwave will be short-lived. A trough of low pressure descending from the Pacific Northwest is expected to arrive late Saturday into Sunday, bringing with it a chance of showers, especially in the mountain areas like Julian. This shift will also usher in cooler, drier air, leading to a noticeable drop in temperatures by early next week. By Tuesday, temperatures are expected to be 5 to 10 degrees below average, providing a welcome relief from the brief heat.

**How to Prepare:**

  • Stay hydrated, especially during peak heat hours.
  • Limit strenuous activities during the hottest part of the day.
  • Monitor weather forecasts for updates on shower potential.

**Who This Affects Most:**

  • Individuals sensitive to heat and humidity.
  • Outdoor workers and athletes.
  • Residents in inland areas where temperatures will be highest.
