Low Pressure System Will Bring Cooler Weather to So Cal
A ridge which has been lurking off the coast the past few days will move ashore, bringing light winds, clear skies and above normal temperatures today. Highs will range from the 70s at the coast to the lower to mid 90s in the valleys in the valleys which is about 10 degrees above normal. RH recovery was only fair in a few desert-adjacent areas last night and readings are only around 20-30% early this morning. Expect minimums to reach the 10-15% range again this afternoon across most areas of Southern California away from the coast. Friday into the weekend, a trough will move from the Pacific Northwest into the northern Rockies and Great Basin. This will result in cooler, onshore flow. Highs by the weekend will drop into the 60s along the coast to the lower 80s in the valleys. Some stratus may return to the coastal areas from Los Angeles County southward. It will turn windy each afternoon along the central coast, the Kern County Mountains and the Banning Pass Saturday and Sunday with wind speeds reaching the 20-30 mph range. In addition, local north winds of 15-25 mph will be possible each night beginning Friday in Santa Barbara County and the I-5 Corridor
