SYNOPSIS
29/835 AM.
Mostly clear skies and warmer temperatures will prevail across the region through this week, although some night through morning coastal low clouds and fog can be expected at times. Gusty northwest to north winds will prevail over the mountains and deserts at least through Tuesday.
.SHORT TERM (TDY-WED)...29/834 AM.
***UPDATE***
A weak eddy brought low clouds and fog into parts of the L.A.
County coast early this morning. Low clouds and fog also formed over interior areas of northern SLO County as well as the eastern Santa Ynez Vly. These low clouds are forecast to dissipate by late this morning. Otherwise, sunny skies covered the forecast area this morning which will continue thru this afternoon.
Northerly pressure gradients increased early this morning helping to keep gusty NW to N winds over portions of the SW SBA County mtns and coast, VTU County mtns, L.A. County mtns along the I-5 Corridor, and the western Antelope Vly foothills into the Antelope Vly. Advisory level wind gusts to 40 to 50 mph at times can be expected in these areas today, especially this afternoon, and Wind Advisories will continue. Breezy to gusty W-NW winds will also affect much of the coast and adjacent vlys thru this afternoon, strongest on the Central Coast where winds could approach Advisory levels at times.
A flat upper level pattern with H5 heights around 576 dam will persist over the area today, helping to keep temps near normal to a few degrees above normal. Highs this afternoon for the inland coast, vlys and lower mtns should reach the 70s to low 80s, with the warmest temps in the western San Fernando Vly.
***From Previous Discussion***
Not much going on for the next three days. Winds will be the only concern. The state will be under NW slightly cyclonic flow through the period with hgts near 576 dam today and Tue falling to 574 dam on Wed. There will be continuous offshore flow from the north through the three day period peaking near 5 mb early Tuesday morning. There will be weak onshore flow to the east both today and Wednesday but it will be weakly onshore on Tuesday.
Skies will be mostly clear through the period. The only possible exceptions will be some night through morning low clouds over two small areas. The first area will be the western portion of SBA county where west winds will create back building low clouds in the Santa Ynez valley which will spread back into the coastal plain. The second area will be the LGB-LAX area where a weak eddy may bring some low clouds up from the south in the early mornings.
As mentioned above winds will be the biggest issue over the next 72 hours. The offshore N to S gradients will combine with the northerly upper level flow to produce periods of advisory level winds from now until Tuesday afternoon and beyond into Wednesday. The winds will peak tonight as the offshore sfc gradients reach their peak. Due to the diurnal cycle of the pressure gradients there will be lulls in the winds esp in the afternoons and early evenings. Please see the product LAXNPWLOX for all of the wind advisory informations.
Most areas will warm today and Tuesday. Max temps will cool some on Wednesday as the offshore flow relaxes. Most max temps across the csts/vlys will be in the 70s with a smattering of lower 80s in the warmest vly locations. These max temps will be a few degrees either side of normal.
.LONG TERM (THU-SUN)...29/319 AM.
The EC and GFS both ensembles and deterministic runs are in decent agreement Thu and Fri. At the upper levels there will be increasing troffiness which would normally cool things, but another round of offshore flow from both the north and east will prevent that and actually warming to the coasts and vlys. On Friday a reversal to onshore flow will bring increased morning low clouds and cooling to the csts and vlys.
Mdl agreement wanes sharply for the weekend day 6 and 7 forecast.
The GFS and esp its deterministic run is steadfast in its resolve to bring a late season storm to the area. The EC and most of its ensembles just run a broad trof over the area. The GFS ensembles are pretty varied and do not strongly support the stormy scenario.
At this time the weekend forecast is biased towards the EC solutions and is dry. There will be a cooling trend each day with the GFS coming in much cooler than the EC. Again the cooling trend has been slanted in the EC's direction. Still need to keep an eye on the evolution of the GFS's fcst and if the EC shows any trend towards a deeper wetter soln as well.
AVIATION
29/1739Z.
At 1719Z at KLAX, the marine layer was 500 ft deep with an inversion top at 2300 ft with a maximum temperature of 17 C.
High confidence in TAFs, except for KLAX and KLGB (30% chc of no cigs), KSMO (40% chance of IFR cigs from 12Z-16Z Tue), and KOXR (15% chance of IFR cigs after 14Z Tue).
KLAX...Moderate confidence in TAF. There is a 30% chance of no cigs developing tonight. No significant easterly wind component is expected.
KBUR...Moderate to high confidence in TAF, some uncertainty in wind direction after 04Z Tue.
MARINE
29/947 AM.
For the outer waters, the extended period of gale force winds is expected to continue thru at least Tue night. Swell will continue to be short- period and choppy, with the potential for dangerous breaking waves at west- facing harbors. SCA conds are expected for the outer waters, Wed thru Fri, with a 30% chance of gales persisting into Wed night.
In the inner waters N of Pt. Sal, SCA level winds are likely thru Tue night, with a 25% chance of gale force winds this afternoon/evening. Then, there is a 50% chance of SCA conds during the afternoon/evening hours Wed thru Fri. Seas are expected to be at/near SCA level through Wed.
In the SBA Channel, SCA level W-NW winds are expected, particular across western portions, during the afternoon thru late night hours thru Wed. Winds will likely remain below SCA levels for eastern portions of the channel, most of the time through the period.
In the southern inner waters, there is a 20% chance of SCA level W to NW winds across northwestern portions, mainly from Anacapa Island to Malibu during the late afternoon thru late evening hours today thru Tue.
BEACHES
29/947 AM.
Persistent strong winds and outer water swell heights of 10-15 feet with a 10 second period will lead to high surf (8-12 feet)
along the Central Coast this afternoon through Tuesday night.
Surf will be highest across northwest-facing beaches. There is a 40% chance of high surf advisory criteria lingering through Wednesday evening. NO coastal flooding is expected.
