SYNOPSIS. 08/312 AM.
Scattered rain and mountain snow showers will continue through early Friday with light snow on the major passes this morning. The weekend will be dry with a slow warming trend.
SHORT TERM (TDY-FRI). 08/233 AM.
The upper low responsible for all of this week's weather has started its eastward trek and is now to 60 miles south of Santa Rosa island. All mdls (xcp the HRRR) agree that the upper low will approach the coast around noon. It will then accelerate to the ENE and by late afternoon it will be halfway to the NV state line and will be over the southern portion of the NV/CA state line after midnight Thursday morning where it will sit and spin through most of the day Thursday. The low will then make a return engagement Thursday night as it retrogrades back to the coast Thursday night. This very pesky low will then finally exit the area to the SE on Friday and Friday evening.
Rain will be circling the forecast area like horses on a merry go round today but will be just outside of the forecast area resulting in a mostly dry day. The best chc of rain will be over the eastern edge of LA county and the mtns. The flow pattern will change later this afternoon as the low center moves into the state and NE flow sets up over SLO/SBA/VTA/LA counties. Rain will increase across the interior sections and the northern portions of the mtns (eastern mtns in SLO) in all four counties. This up tick in rainfall will last through the night and most of Thursday as well. There is a chc that some showers will make it over the mtns and into the coasts and vlys but if any do they will not produce much rainfall.
This system has no history of thunder and as it has spun and meandered around the area the cool pool of air aloft has modified and increased the stability of the atmosphere. Will be removing the chc of TSTMs in the morning update.
Some cooler air will advect into the mtns this morning and the snow level will fall to 4500 feet. This is low enough to bring some rain mixed with snow to the Grapevine but at this time it does not look low enough to create serious problems for motorists on I-5. Snow levels will then rise to 5000 to 5500 feet by this afternoon. Travel is not recommended into the higher reaches of the mtns where a Winter Storm Warning is in effect. A foot or more of new snow is possible above 6000 ft. A Winter Storm Warning for the LA and VTA mtns is in effect until 500 AM on Friday and a Winter Weather Advisory is also in effect until 500 AM on Friday for the SBA mtns. Please see the product LAXWSWLOX for more details.
Very low confidence in rainfall amounts over the next 24, 48, and 72 hours. The showery nature of the rainfall will make the amounts very non-homogeneous. The usual problems with getting the vagaries of the movement of upper low correct will also contribute to the uncertainty of where and how much. The current consensus forecast call for a quarter to half inch of additional rain to fall over the coasts and vlys (This may be overdone, the forecast counts on quite a bit of rain make it over the mtns and fall on Thursday and would not be surprised if these cst/vly numbers will need lowering) and double those amounts for the interior sections and northern portions of the mtns. Two inch amounts of rain or liquid equivalent are possible across the north facing and highest elevations of the eastern portions of the San Gabriel mtns. Rainfall rates should not exceed a half inch per hour and will more likely top out at a quarter inch per hour.
There will be some peeks of sunshine today and the majority of the clouds will orbit outside of the four county area. Thursday will be a cloudy day as the upper low spins clouds over the area from the NE.
Across the csts and vlys: Max temps today will mostly be in the lower to mid 60s fall a few degrees Thursday to a few degrees either side of 60.
The upper low will depart to the SE on Friday and will take the rain and clouds with it. It will likely be partly cloudy and dry over SLO and SBA counties. LA county will start out cloudy with some chc of rain showers but these will clear and dry out by early afternoon. VTA county will clear and dry out quicker than LA. Max temps will rebound on Friday and will top out in the mid to upper 60s across the csts and vlys.
LONG TERM (SAT-TUE). 08/310 AM.
The February like weather all comes to an end Friday night. A huge CONUS spanning trof will develop over the weekend and persist into early next week. CA will be under the dry NW flow on the west end of this trof. It will usher in a period of benign weather. Skies will be partly cloudy at worst through the period. Hgts will change little through period and no offshore flow is forecast so max temps will really not change much through the period (maybe a little warmer on days 6 and 7) and will remain several degrees blo normal.
AVIATION. 08/1230Z.
At 1130z at KLAX . there was no inversion.
Overall . Low to moderate confidence in the current TAFs. Precipitation and associated low CIGs will continue to move through the region during the forecast period, changing direction as the center of the low moves south and east. CIGs and at times the vsby will vary frequently through the forecast period, especially during periods of showers. MVFR/VFR conditions will be most prevalent with a chance of LIFR/IFR conditions near heavier showers.
KLAX/KBUR . Low to moderate confidence in the current TAF. Rain and associated low CIGs will move SE to NW around the terminals this morning. As the low pressure center shifts south and east, the rain bands will first become E to W and then N to S. CIGs and at times the vsby will vary frequently through the forecast period, especially during periods of showers. MVFR/VFR conditions will be most prevalent with a chance of LIFR/IFR conditions near heavier showers. At KLAX, there is a ten percent chance of east winds greater than 8 kts through 18z and a thirty percent chance 09/12z-17z.
MARINE. 08/241 AM.
There is a slight chance of thunderstorms across the southern waters this afternoon and evening. Locally strong and gusty winds, deadly lightning, and brief waterspouts are possible near thunderstorms.
Otherwise conditions will remain below advisory level through Friday with winds increasing across the outer waters Saturday and Sunday.
