-
With the recent more extra-ordinary rains in and through the PNW more over the past four or five days @, looked at together with what I've pointed to more just yesterday where looking at main and greater patterning impacting the West @, ...
 
.. These two, looked at more in particularly of the broader scope of elements currently more observable at this point (Others, ENSO's current state, together with the general positioning or focusing of main cold to the north at this point more seasonal.), and if again looked at together, would I'd say, work as serve as a decent harbinger of an at least more average precip. type of fall and winter seasons for California both north and south where looking ahead.

Where do Bay Area guys go for snow?

 

Sierra Nevada resorts.

[Guest happ]

Moisture from former hurricane Kevin is mainly falling in eastern Arizona though there was some development over SoCal mountains. 

 

85 / 63 [coolest minimum in a month]

.. Up Interstates both, 80 and 50. "Mammoth" is the only resort I know of on 50—or more south even maybe.

 

"Boreal", "North Star", "Sugar Bowl", "Donner Ski Ranch", "Alpine Meodows", "Squaw Valley", all more just of I-80. "Heavenly" a bit South of Tahoe. ...

[Dan the Weatherman]

It got down to 58.8 degrees this morning here in Orange, which is downright cool for early September. This would be more normal for early October. It does appear, however, that the heat will be returning big time late this week with inland O.C. getting into the 90's.

THERE IS A LITTLE BETTER AGREEMENT BETWEEN THE GFS AND EC WITH THE 
  HANDLING OF TROPICAL DEPRESSION 15-E...WHICH WILL LIKELY STRENGTHEN 
  TO TROPICAL STORM LINDA. SOUTHERLY WIND FLOW BETWEEN THIS SYSTEM AND 
  THE UPPER HIGH OVER MEXICO WILL DRAW TROPICAL MOISTURE NORTHWARD 
  INTO BAJA. PWATS OF 1.5" HOVER OVER THE U.S.-MEXICO BORDER TUESDAY 
  THROUGH THURSDAY...BUT THE REAL DEEP MOISTURE (PWATS 2+ REMAIN 
  SUPPRESSED TO THE SOUTH...SO ANY CONVECTION THAT DOES FORM OVER SO-
  CAL WILL BE ISOLATED AND MOSTLY CONFINED TO SAN DIEGO AND RIVERSIDE 
  COUNTIES. AFTER THURSDAY THE MOISTURE DECREASES AS LINDA BEGINS 
  TURNING NORTHWEST AND THE UPPER HIGH BUILDS SOUTHERN CALIFORNIA 
  BRINGING HOT...DRY WEATHER NEXT WEEKEND.

Looks like a hot week ahead.

It sure does look hot. Wednesday through Friday could be a lot like the last couple of heat waves we had experienced in August. I would like to see some more in the way of monsoonal moisture this time around as it has been unusually dull here for about the last month. I just think it is atypical during an El Nino of this magnitude not to have any t-storm action in the vicinity whatsoever.

Mammoth is well south of the 50. By a couple hours in fact down the 395.

Acton experiencing its own private arctic blast?

 

Send some down here!

I wish that was the case and wonder how long we must wait for an "arctic blast" in SoCal?

 

95 / 70

[Alan]

Last arctic blast was the 1st of the year 2015 I recorded a 17/10 which is my record low high temp for my location (just 8 years though) - my guess is we're more than half way to the next one! LOL

The first few days of January 2015 produced minimums in the 30's even in the lower elevations though only 40° at my station [my coldest temp for the year so far].  This past year has been way too warm w/ only 9 nights below 50° at this point; that has to be a new record.  Today there is an "Excessive Heat Warning" in effect.

Very hot here in Orange today as it reached about 101 to 103 degrees depending on which thermometer I was looking at. This is much like the hot spells earlier in August.

 

There is a brush fire burning in the Coyote Hills area between La Habra and Fullerton and is currently about 15 acres.

[Guest happ]

Very hot today but I enjoyed the cumulonimbus build up over the San Gabriel Mts.  Dewpoints were high though some inland areas dropped below 60 this afternoon; Pasadena had a heat index of 106.  Maybe humidity from hurricane Linda will allow for more widespread thunderstorms tomorrow.

It rained to the north [santa Clarita], the south [santa Ana] and to the east [Ontario] but none here in LA.  Some minimums include Burbank: 80°, Pasadena 81°.  I've recorded a few 80° minimums over the many years; they were associated with very high humidity and clouds.  But last night was clear with little radiative cooling.

Curiosity of the day:  John Wayne Airport set daily records for both high temperature (95) and precipitation (0.29"):

Are you still in Eugene?  You might want to stay in Oregon considering how hot Septembers are in California.

[Dan the Weatherman]

According to my thermometer (on the north side of my house), the low this morning here in Orange was 75 degrees and the high was 102.2. I also picked up .05" from the thunderstorms this afternoon.

It has been muggy today and is very muggy tonight with the tropical airmass in place.

[Jesse]

Returned to Tujunga just in time for the latest heat wave.  My work is in L.A., but I usually have time off in the summer.

 

Since I started spending my summers in Eugene in 2013, each has been among the hottest ever recorded, including this year at #1.

 

Ironically, one of the main factors that decided me on Eugene for a second home was the cooler summers  <_>

 

Supposed to be yet another 90+ day in Eugene tomorrow.  I'll be browsing real estate listings in Juneau 

 

Hopefully we don't see a trio of summers like the last three for at least another couple hundred years.

[Guest happ]

Cloudiness from Linda help knock the temps down a little today but dewpoint temps were higher compared to yesterday.  The clouds probably lessened thunderstorm development also.

 

97 / 78

[Guest happ]

Nights have been very warm since earlier in the week.  Some models are suggesting rainfall over much of California next week!

 

L: 77°

[Mattywx101]

The warmer then average ocean temperatures have sure been making its presence known on the immediate central coast.  Our temps from July 1st to August 31st have averaged out to  74.8/ 61.3,  50 year average 68.9/ 53.8.   Hottest temp of the summer: 103 on September 9th, Lowest min: 49 on September 4th.       

[Mattywx101]

Welcome to the forums! Hope to see you and more Californians join us this winter!

Thanks.   Hopefully we'll get a winter out here this winter.   High today: 76, ...Ave:  69. 

[Guest happ]

Warm muggy mostly cloudy day that reminds me of Hawaii.  Some light rainfall in places [mainly higher elevations] with the possibility of more significant moisture in a few days.

Welcome to the forums! It is nice to see another new member from CA on here.

 

Hopefully we get a very wet winter with a lot of snow in the mountains after a dismal four year stretch. This is our best opportunity that we have had for a good season in quite a while!

[Dan the Weatherman]

There were a few sprinkles / light showers in the Santa Ana Mountain and foothills region late this morning. It was another day in the mid-upper 90's here in Orange and is still in the upper 70's at 9:30 tonight!

Thanks.  I feel pretty optimistic about this winter myself.  Statistically the odds are increasing our favor.   I like seeing colder Lows in the GOA these last few weeks.

The remnant moisture of tropical cyclone Linda remains well offshore as a trough moves closer to northern California.  We need this rain desperately.

 

92 / 72

[Mattywx101]

Its raining moderately off and on around San Simeon this morning.  Temperature 64, Dew Point 61.  It looks like the mid level moisture, left over from remnant Linda, has a lifting mechanism off the coast west of SLO county now, where there appears to be some upper level circulation to the west of the Monterey Bay with enhancement of the mid level moisture field and cooling cloud tops per satellite images.  The biggest concern with all of this blooming activity is the potential for dry lightning, which is the last thing we need right now.

 A JET STREAK IS MOVING DOWN THE COAST THIS MORNING AND IS 

  INTERACTING WITH A SMALL AREA OF ELEVATED INSTABILITY OFF THE 

  CENTRAL COAST...PRODUCING AN AREA OF CONVECTION ALREADY VISIBLE ON 

  SATELLITE. THIS ENHANCEMENT SHOULD MOVE THROUGH SLO COUNTY 

  TODAY...AND COULD BE POTENT ENOUGH TO PRODUCE LOCALLY MODERATE 

  RAINFALL AND A COUPLE OF THUNDERSTORMS.

 

Good luck with the precipitation.

Thanks.  Rainfall:  0.12" so far with this one.  Rain, continues to vary from light to moderate near San Simeon.  Current temp holding at 64,  Dew point 61.  

[Dan the Weatherman]

There is a low level cumulus deck here in Orange today, which is almost always a positive sign when there is rain in the forecast. This indicates that the lower levels of the atmosphere are moist as opposed to being dry.

[Guest happ]

It began raining around 3am and lasted 6 hours.  Steady occasional moderate rainfall.  I was astonished to see 1.98" before I left for work.  Incredible orographic lift.  USC, Santa Monica, Beverly Hills have over 2 inches.  I think LA was the sweet spot for this system unlike hurricane Dolores where Orange Co/ San Diego picked up extraordinary totals [over 4 inches in Ramona in July].

 

Lo: 70

[Mattywx101]

0.81" here so far.

 

When is the last time there were two rain events with this magnitude and coverage in one summer?

Wow.   That's is an substantial amount for this time of year.   Looking at this site:  http://www.climatestations.com   and looking at Los Angeles historical data, the last time something like this may have happened was in 1976 or 1977.    But as far as magnitude and coverage, I think this summer pales those other ones from what I can tell. 

 

Temp yesterday 71/61.  Rainfall:  0.15"
