|Imperial County Weather Synopsis|
|SYNOPSIS FROM THE SAN DIEGO OFFICE
Hot weather will continue through the weekend and into next week with nearly stationary high pressure over the Western US. Monsoon moisture will bring chances of thunderstorms each day, mainly over the mountains. Tropical Storm Lidia, currently just South of the Southern Baja California Peninsula, is forecast to move northward, but eventual dissipate as it begins to turn more westerly near Central Baja. Peripheral moisture from this system may move into Southern California early next week, potentially increasing the risk of showers and thunderstorms.
SYNOPSIS FROM THE PHOENIX OFFICE
Above normal temperatures will continue through Friday, but will trend sharply downward this weekend as deeper tropical moisture moves into the area from the south. Thunderstorm chances will remain very limited across lower desert communities through the rest of the work week with activity focused mainly over mountain areas. As moisture and humidity increase this weekend, the threat of showers and thunderstorms increases especially over the southwest Arizona and far southeast California deserts. Drier and warmer conditions return early next week along with isolated mainly afternoon and evening thunderstorms.
