Temperatures this morning will be near average, starting out in the mid 70s. There will be a few stray showers throughout the afternoon and evening, but they will be very spotty in nature so don't cancel your outdoor plans. Temperatures will be hot, rising to the mid 90s as humidity levels stay lower than the past several weeks.
Monday and Tuesday will be mainly dry and hot. Lows will stay in the mid 70s and highs in the mid 90s.
Tropical moisture could come into play late in the day Wednesday mainly south of the Bay area with a better chance of rain Thursday. Right now the greatest threat of steady rain comes later in the day Thurusday through Saturday, but its still too early to tell exactly where the next system will go.
The tropical wave in the NW Caribbean has yet to form, but is expected to over the coming days either in this region or the southern Gulf of Mexico. Once it develops, it will be in a conducive environment for strengthening and could become a tropical depression and possibly a Tropical Storm as it moves north then northeastward. We will closely monitor this as it may have impacts on the Bay Area late next week. For now it has a 60 percent chance of development.
Another wave is expected to move off the African coast in late Sunday or into Monday and has a good possibility of development as it moves through an environment conducive for development. It has a 40 percent chance to develop over the next several days.
Two other weak waves, one the remnants of Gordon, has little to no opportunity to develop any further as the waves move north into colder Atlantic waters and a very dry environment.
