A slow moving low pressure and upper level low will result in the potential for isolated thunderstorms through the weekend with temperatures in the low-80s. Best chances for these diurnally driven thunderstorms would be in the afternoon hours. There’s a good amount of moisture in the air this weekend with steady southerly flow, so these storms could produce heavy rain, though severe weather is not anticipated. Past this weekend, a warmup to the mid-upper-80s (90s in interior) is forecast as upper level ridging and high pressure builds next week.

Saturday – fog early with cooler, marine flow. Temperatures warm into the low-80s with chances for scattered showers and thunderstorms particularly north and west of the city. Overnight lows in the upper-60s.

Sunday – Similar pattern to Saturday with partly sunny skies, isolated showers and thunderstorms developing later in the day particularly west of the city. Overnight lows in the upper-60s.

Monday – this pattern persists with partly sunny skies, highs in the low-80s and chances for isolated PM thunderstorms. Overnight lows in the low-70s.

Tuesday – high pressure builds offshore, with upper level ridging and 500 mb temperatures increasing, we should see sunny skies and very warm temperatures nearing 90ºF. Overnight lows in the mid-70s.
