Weather may have been boring, but at least tonight's sunset was not boring.  

Beautiful clear day today, went for a pleasant walk.

I ended with 1.34" shortly before midnight. I'm more than satisfied with that. Drove up to Anza east of Temecula earlier today, snow is still on the ground above 3200 FT. Very cold and windy up t

Very hazy today. Can't even see the Santa Ana Mountains even though they're right there.

A dry February so far, but at least it's not also an unseasonably warm one. Temperatures have been surprisingly moderate.

Rainy season up to this point looking lackluster so far at my location in Murrieta. It is not over yet, however. March or April could possibly feature a decent storm or two and keep the 2020-21 season from ending too far below average.

Clear day down here in southwestern Riverside County today, but the webcam view of the Los Angeles Basin from Mount Wilson tells a different story there this afternoon.

Much cooler today.

NWS hinting at a possible chance of precipitation as a trough swings in around March 2-3, but the rest of February looks dry.

No wind here either. Went for a nice walk west of Murrieta but stumbled upon a broken water pipe shooting water all over the hillside. Reported to CalFire who’ve said they’re responding to it.

There was a slight uptick in winds this afternoon, but that has already faded. Humidity has plummeted. Supposed to be much warmer tomorrow.

82 in San Diego today.

Rare time when the coasts are warmest, it was only 71F here inland.

76F here right now, but areas just a couple of miles from me closer to the foothills are much warmer, over 80F already.

Warm again here this morning, but NWS calls for a slight chance of showers late Saturday night into Sunday morning.

Onshore flow should spread cooler temperatures tomorrow.

Onshore flow didn't quite kick in today as previously predicted, ended up still being warm, although not as warm as the past two days (77F here). Every day since last Wednesday has been virtually cloud-free here.

Rain chances have been removed from the forecast all together.

Season totals to-date are looking rather dismal, although there is still chance for even a semi-redemptive month ahead. With any precipitation through the next four days being very unlikely here, we can examine season totals up through February 28 of past rainy seasons and find ones that were similarly low or even lower.

Downtown L.A. has only 4.39 inches to date. The "average" for them by the end of February is close to 10.5 inches. Quite a deficit. Temecula's season total right now is only 4.02 inches. Since 2000, only two rainy seasons were drier up to this point in Temecula: 2001-02 (2.85" through 2-28-2002) and 2006-07 (2.88" through 2-28-2007). Other similar totals were 4.32" by 2-28-2014, and 4.60" by 2-28-2018. My season total is lower (3.35") as I'm just far enough into the valley away from surrounding foothills and mountains that tend to boost rainfall totals for places like southern Temecula.

Even a single good storm (1-2 inches or higher) or more in March or April could prevent the current season's totals from ending terribly low, but it's practically a roll of the dice. What happens (or doesn't) in March will be very important for our season.

Santa Anas kicked up in the middle of the night, immediately ratcheting up temperatures at my weather station. Highlighted here.

I am really concerned by the number of what I call "ultra dry seasons" that we have experienced since 2000. I define an "ultra dry season" as a rainfall year (July 1 - June 30) in which Downtown Los Angeles receives less than 7" of rain for the season. Between 1877 and 2000, only 1898-99, 1893-94, 1923-24, 1958-59, and 1960-61 fell in that category, although there were several other drier seasons that recorded between 7" and 8". Since 2000, 2001-02, 2006-07, 2012-13, 2013-14, and 2017-18 have been all "ultra dry seasons", and if we don't receive much more rain this season, 2020-21 will become the next "ultra dry season". 

To summarize, we had only 5 "ultra dry seasons" between 1877 and 2000, but we have already had 5 since 2000, and possibly going on 6 if conditions don't improve soon!

Dry seasons have been even drier in the last 20 years, I agree. That applied to wet rainy seasons from the late 1960s through the late 1990s as well, but not since, except for 2004-05. That was our last banner rain year.

Onshore flow kicked in this afternoon with a cool breeze.

Humidity still low here.

Walked out near Bear Creek in the northwestern corner of Murrieta on Monday, at the bottom of the Santa Rosa Plateau. This entire area went up in flames during a wildfire in August 2019. It has begun recovering modestly since then.

And today in a different area, south of Murrieta. One of the few areas surrounding the valley that has not yet burned in recent years. Some greenery at the bottom, although the creek was completely dry.
