Oct 21 - 25 The next light rain system is expected Thursday night into Friday as the low pressure frontal zone approaches our area. This will be followed by a break in the rain of about a day. For lower elevation areas this break will be from late Friday afternoon until late Saturday evening or early Sunday a.m. before the more significant atmospheric river system is ushered in. Areas of elevation will receive more rain and a shorter break in the rain, from Friday evening to Saturday late morning, before the larger system arrives. Daytime temperatures for Coastal areas can be expected to be in the upper 50s to low 60s with daytime highs for the Inland areas in the low to high 60s. Areas of elevation will see overnight lows in the mid to upper 40s to low 50s. All areas can expect a small bump in daytime highs Saturday dropping back down the the rain on Sunday. District-wide will also experience a period of elevated southerly winds starting late Saturday night for coastal areas, late Saturday morning for elevated areas and as late as Sunday afternoon for Inland areas. These winds will range in speed from 20-mid 30 mph and last until early Sunday evening for elevated areas and some Inlands areas but extending to early Monday morning for Coastal areas. Due to the rain, winds and cooler temperatures AQIs will be GOOD for PM2.5, 10 and Ozone.
