These cool and cloudy conditions are almost finished in San Diego County. The past few days have brought unseasonably cool temperatures. This will remain through Sunday morning, then daytime highs start to warm.

August is typically the hottest and driest month for most of the county. Rain is possible due to monsoon activity, which is moisture that comes up from the south. The rain observed Saturday morning, though, was due to a trough pushing moisture in from the Pacific Ocean. This pattern is not as common in August, but did bring some rain to the region.

Most of the county remained dry Saturday morning, but some clouds squeezed out some light rain. Totals remained below a tenth of an inch. Here are some San Diego County rain total highlights:

Carlsbad: 0.07"
Encinitas: 0.07"
Ramona: 0.06"
Oceanside: 0.05"
Vista: 0.03"
Escondido: 0.03"
Poway: 0.02"

Sunday morning, a similar pattern of light drizzle is possible. This will favor coastal communities. By Sunday afternoon, clouds should break and sunshine will return.

Starting Sunday, temperatures begin their warming trend. Sunday's highs will climb just a couple degrees and it likely won't feel too different than Saturday. Then, the next few days will see gradual warming. The heat really kicks back in around Wednesday, when highs start to jump back to above-normal. Heat peaks Thursday and Friday, bringing lower 80s along the coast and mid-90s for inland valleys and mountains. Desert communities will see significant warming, jumping from right around 100º this weekend to 115º by the end of this upcoming workweek.

As daytime highs climb, overnight clouds that build will mix faster, making way for sunny afternoons through the upcoming week.

Sunday's Highs:
Coast: 72-79°
Inland: 77-83°
Mountains: 74-84°
Deserts: 95-103°
