Isolated thunderstorm activity in the southeastern portion of our county, along the mountains and deserts, has resulted in a Flash Flood Warning in effect until 7P. Rapid downpours could lead to flooding, something to consider if you're traveling between the Alpine and the California/Arizona border along I-8. Storms could also produce hail and result in abrupt gusty winds.

We'll stick with a chance for scattered monsoon storms through the week, mainly in the afternoons and in our mountains, with a greater increase in severity this weekend.

Daytime highs will be the warmest for the first half of the week then in the second half, we'll have slight cooling. Inland, mountain and desert communities will have the biggest drop in temperatures. By Sunday, we'll trend in the upper 70s in areas like Julian, compared to 90s at the start of the week.

Temperatures will continue to trend about 5-10 degrees above average then by Friday, we'll be closer or below seasonal.

Tuesday's Highs:
Coast: 79°
Inland: 93°
Mountains: 90°
Deserts: 110°
