Warm and dry conditions can be expected through most of next week. There will be some coastal low clouds and fog, but otherwise, skies will remain mostly clear. There will be gusty north winds through tonight and gusty onshore winds through most of next week.
(tdy-Tue), 31/745 AM.
***UPDATE***
Visible Satellite imagery this morning shows low clouds over portions of the LA Basin and Santa Maria Valley. The marine layer stratus is expected to clear by late morning.
Have cancelled the wind advisory across the I-5 corridor. SFC obs show 20 to 30 mph, these winds will continue to diminish. There is likely to be an slight uptick later this afternoon into evening but will remain well below advisory levels.
Another round of Sundowners is expected this evening. However, expecting winds to be weaker with isolated gusts up to 45 mph (such as at Gaviota). Not widespread or strong enough to warrant a wind advisory (20% chance of issuance). Otherwise, the forecast remains on track.
***From Previous Discussion***
Excitement levels are pretty low as we transition from May to June. At the upper levels weak cyclonic flow today and Monday will transition to a benign high hgt (585dam) upper low on Tuesday. At the sfc there will be an increase in onshore flow both to the east and north through the period.
Marine layer stratus will be fairly absent this morning mainly affecting the LA coast and the western SBA coast. The amount of low clouds will increase both days Mon and Tue and by Tuesday most of the csts as well as some lower vlys will be covered. There is not enough of an onshore push or an eddy to keep the clouds in so the late mornings and afternoons (and evenings for many areas) should be mostly clear.
Not expecting any advisory level winds but there will be a stronger than normal sea breeze across the west facing beach and near shore areas.
Most areas will warm a few degrees today, but the Antelope Vly will warm by about 6 degrees with the westerly downsloping winds. The stronger sea breeze will cool the csts/vlys by 1 to 2 degrees Monday while the rising hgts bring 2 to 4 degrees of warming to the mtns and interior. A deeper marine layer and a still stronger sea breeze will cool the Central Coast by about 6 degrees on Tuesday, while the rest of the csts and vlys see 2 to 4 degrees of cooling. Most cst vly max temps will be above normal today and Tuesday but will fall blo normals on Tuesday.
(Wed-Sat), 31/220 AM.
June weather will be in full swing during the xtnd portion of the fcst. A small ridge will nose into the area from the west on Wed and Thu and hgts will rise to about 586 dam. Then a decent sized upper low will push into the PACNW and hgts will fall to 578 dam on Saturday. Mdt to strong onshore flow will persist through the period strongest in the afternoon.
There will be night through morning low clouds across the csts through the period. The vlys will likely wake up to stratus on Saturday. Some beaches may struggle to clear on Fri and Sat.
Other than a stronger than normal seabreeze there will be no wind issues.
Most areas will warm on Wednesday as hgts rise and the onshore push will be at its lowest point in the 4 day period. Some cool air advection will lower Thursday's temps by a few degrees over most of the area. Stronger onshore flow and lowering hgts will bring a couple degrees of cooling to the area both on Friday and Saturday. By Saturday most max temps will be 3 to 5 degree blo normal with vly highs only in the mid 70s to lower 80s.
