Marine layer clouds with patchy fog will reoccur each night from the coasts to the coastal valleys, expanding into the valleys into this weekend. Temperatures will trend cooler, with below normal temperatures through the weekend.
(tdy-Sat), 25/212 AM.
The flow overhead will become more and more cyclonic as a very large upper low works its way into and thru the PACNW. Hgts will fall from 590 dam to 584 dam by Saturday afternoon. Moderate to strong onshore flow will be present for all three day as well. The onshore flow will be strongest (8-9 mb) to the east and in the afternoons.
Look for three similar days today through Saturday. There will be plenty of low clouds and fog covering almost all of the csts and much of the vlys. Clearing will be slower than normal and a few beaches will see no clearing at all. The low clouds will also arrive earlier than normal as well. The only exception will be the western portion of the SBA south cst where local north winds will likely keep the region cloud free.
Max temps will fall 1 to 2 locally 3 to 4 degrees per day across most of the area. By Saturday even the vlys will be in the 70s. These max temps will be 3 to 6 degrees blo normal across the csts and 6 to 12 degrees across the vlys.
There will be gusty west winds across the Antelope Vly in the afternoons with peak gusts approaching advisory levels. There will also be gusty NW winds across the SW portion of SBA county in the evenings and overnight. These gusts will likely reach advisory levels Friday evening.
(Sun-Wed), 25/237 AM.
June Gloom will continue unabated through at least the 1st of July. A series of upper lows will rotate through the PACNW and keep cyclonic flow over the state. Strong onshore flow to the east will continue through the period. There will be moderate onshore flow to the N in the afternoon, but only weak onshore flow in the mornings.
Night through morning low clouds and fog will continue through the period pushing over the csts and deep into the vlys. Clearing will be on the slow side with some west facing beaches not clearing at all.
Strong near advisory west wind gusts will affect the Antelope Vly each afternoon due to the strong onshore push. NW winds will likely continue to affect the SW corner of SBA County in the evenings.
Max temps will not change much through the period. Looks for mid and upper 60s at the beaches; lower to mid 70s across the rest of the csts and mid and upper 70s across the vlys. These temps are 3 to 6 degrees under normal for the csts and 6 to 12 degrees cooler than normal for the vlys.
