2017 California/Southwest Weather Thread

Recommended Posts

Crescent City typically gets a lot of rain in the winter and a lot of fog in the summer. Many days in July and August they will not reach 60 F due to the fog and cold sea breeze. Sometimes a summer storm will come and cut off the inland heat and wipe out the marine layer. Those days can be warmer than most summer days on the Northern California coast.

There's a world of difference between the extreme northwest [Del Norte county] corner of California compared to the southeast [imperial county] corner; this becomes ever more evident during spring/ summer.  Several posters have identified the temperature anomaly over the Western U.S. this winter w/ the PacificNW averaging well below normal and snowy versus warmer than normal/ rainy over parts of the Southwest. California has fallen in between; stations in northern California, like Crescent City/ Eureka/ Redding are examples of negative departures.

 

ECMWF now is a little more encouraging for rainfall next week in NorCal.

 

Tuesday: 78/ 48

California storms: Wettest water year, so far, in 122 years of records

The statewide precipitation values given by NCEI “represent area weighted average of values observed at weather stations across the state,” according to Nina Oakley, a California Climate Specialist with the Western Regional Climate Center, part of NOAA.

Crazy to think that when we talk big California winters it won't be '69, '83, and '98 now as the 3 we compare to. 16-17 will be the tops. Well at least for those north of Santa Barbara.

Drought conditions have improved in Santa Barbara area as of March 7, despite getting little rain. Nice to finally have a warm weekend coming up, though more rain would be beneficial for the second half of March. I know many people would not mind if it rained every day from the beginning of November to the end of April, but those are people who don't enjoy walking in warm and sunny weather, at which the green hills look the prettiest. Nice place to go for a walk is Laguna Niguel Regional Park.

 Take some photos of the park. I'm heading out to Anza-Borrego next week.

Doesn't have to be one or the other. There can be people who like both.

That's why it is nice to alternate between cool and rainy weather and warm and sunny weather, but recently we've had all our sunny weather on weekdays and all the cold and cloudy or rainy weather on weekends. Rain is fun to watch, but not great for walking.

This weekend is going to be sunny and warm, and possibly even hot in some areas on Sunday.

I suppose today would qualify as an early spring heatwave though max was below 90° here. Wonder when it will rain again?

 

88/ 62  

 

I hope we get rain again sometime later this month into April. If we don't get any more rain from this point onward, we are going to likely have even hotter spells of weather than we are currently having later on in April and May.

Troughs/ rain obviously lower max temps but long periods of sunny/ dry weather don't always translate into bad or more frequent heat waves. Thankfully, early season ridging/ heat doesn't mean more heatwaves even if it remains quite dry. March 2015 had 13 days 85° or above but April & May only had 4 days each.

It is when the rainy season ends very early such as the end of February or the beginning of March and very little to no rain falls for the remainder of the winter and early to mid spring is when we have increased risks of more spring heatwaves from what I have noticed during past years. March 2015 was a very warm and very dry month after a storm dropped some rain during the first week of the month, while April was rather dry but cooler with a minor rain event at some point. May turned much cooler and was much wetter. I recorded nearly 1.5" of rain here in Orange with the mid-month storm. Even though the winter of 2015 was much drier than average, and most of March was warm, at least the rains returned during the spring, helping to stave off further bouts of heat later into the spring.

 

I am hoping that at least some storms return to Socal sometime during the spring as they did back in May 2015.

The transition from wet to dry season can be delayed by an active Pacific pattern. I think it is a knee-jerk reaction to get panicky but understandable after years of drought. April and even May can produce some decent monthly totals. 1995 was a great year w/ over 8 inches in March followed by several smaller storms into May. As you point out, 1997 was, on the other hand the opposite w/out any rain after Feb 17 and hot only to be followed by record breaking rainfall [4.58] in May 1998. B)

 

Anything is possible after a wonderful winter

Unlike almost every other major city, I think LA has some of the most dramatic temperature differences within relatively short distances. Fog didn't clear at LAX w/ max only 67°. Just 8 miles inland it was 88° at USC and in the 90's elsewhere within the city limits today.  There can be appreciable temp differences in San Francisco between Pacifica and SFO and in San Diego between Lindbergh Field and Rancho San Diego. But Los Angeles must have the record for such wide temperature spreads.

Add in the fact that the highest point within the city limits is over 5,000 feet and you have a pretty remarkably geographically and climatically diverse city.

Planning an early morning drive down to the Anza-Borrego tomorrow before this extended heat burns up the wild flowers.  It was 96° there yesterday [100° in Thermal].  The park website warns of heavy congestion/ large # of visitors. I plan to take highway 79 out of Temecula and Route 22 into the park; hope to avoid traffic. Has anyone hiked into Hellhole Canyon/ Borrego Palm Canyon?

I'm getting tired of persistent ridging even if the heat is not that hot.

 

88/ 62

 

I am ready for some more rain soon and that looks like a possibility next week. I would be really tired of this dry pattern if I didn't see storms in the long range. It was a bit too warm for my liking today and reminds me a bit of March 2015, which was a relentlessly warm and dry March.

7 consecutive days of 80's/ low 90's is enough. Next week is looking better with each model run.

This is beautiful weather. No one here enjoys warm weather.

 

I remember one of our rainiest years ever, probably El Nino, we had a very wet January (insanely wet), a very wet March, and some mid February heat waves. I think Downtown L.A. got about 30 inches that winter.

 

Yes it isn't bad especially w/ low dew points away from the coastline. But I don't want to start relying on air conditioning so early in Spring.

You are thinking of 1994-95, and I remember that February heat well. It approached 90 degrees at least on a couple of occasions during that period with some weak to moderate Santa Ana winds. I remember getting together with my relatives to celebrate my uncle's birthday that February in Irvine and it was very warm for the time of year, even late into the afternoon.
