KEY MESSAGES

- Warm, dry, and breezy weather through the weekend. Widespread 70s on Sunday with a Red Flag Warning for areas east of HWY 24.

- A cold front arrives Sunday night with a slight cool down and isolated showers through Monday.

- Another slow warm up is expected by mid work week with mostly dry conditions.

DISCUSSION

WEATHER PATTERN OVERVIEW:

Synoptic upper ridging will allow for large scale subsidence and much warmer than average temperatures this weekend. While a dry cold front brings some mid-level cloudiness and stabilized temperatures today, another one late arriving Sunday night brings particularly warm/dry/breezy conditions ahead of it with highs near 80 degrees.

After the cold front arrives Sunday night, a northwest flow aloft will bring much cooler temperatures Monday with scattered showers. As another upper level ridge expands eastward, the pattern will rebound temperatures to seasonably warm levels.

FORECAST CONFIDENCE & DEVIATIONS:

Increased winds/wind gusts and max temp, and lowered min RH for day 1-2. Slightly increased PoPs for day 1 based on radar and to better match up with neighbors in southern zones. There is high confidence in minRH as low as 10% tomorrow, with moderate confidence in temperatures reaching low 80s.
