Heat advisory issued for San Diego deserts
SAN DIEGO (KUSI) — A ridge of high pressure sitting over Nevada is bringing very hot temperatures Wednesday but the marine layer is expected to return over the weekend, cooling San Diego slightly.
A shallow marine layer and light fog will hang over the San Diego coastline in the morning hours, but it is expected to lift quickly. Plenty of sunshine will shine on the county Wednesday.
High heat is expected to continue for the next few days. The National Weather Service issued a heat advisory for desert areas effective 10 a.m. Wednesday until 8 p.m. Thursday. High temperatures are expected to be between 111 and 116 degrees Wednesday and Thursday.
The ridge of high pressure will begin to break apart over the weekend. Monsoonal moisture is expected to return and temperatures will begin to cool, but light showers and thunderstorms may be possible for mountain areas.
Wednesday’s high temperatures are expected to be 79 degrees along the coast, 94 degrees inland, 84 degrees for the mountains and 112 degrees in the deserts.
