    2. The pattern definitely doesn't look good for rainfall. We might get a small system to sneak into the area, but I agree, it looks mainly dry for a week or two.

      Delete
  2. Agreed. This is the first El Nino type storm system of the season. There was a brief atmospheric river with this system, though it got cut off at the last second. Otherwise, our rain totals would have doubled. Regardless, it's nice to see a slow soaking rain!

    1. Agreed. We have a chance for rain from Sunday night through early Friday. It will be interesting to see how it all pans out - computers are typically unreliable in these types of active weather patterns.

    3. The El Nino just came a little late. It's definitely NOT a La Nina.How much are these climatologists paid anyway?

    4. Typically El Nino arrives in January with a split jet stream. It is right on schedule. In fact, quite classic.

    1. It's zoomed out and contoured, so it will only give a rough picture of actual rain totals around the area. With that said, San Diego (KSAN) has received 5.01" so far this year, and the map shows us in the 5" contour.

      I'm still trying to find a regional map of rain totals that is regularly updated. It would be amazing to see the difference!

  14. Nice rain fall in Carlsbad the past 24 hours.

  15. Why do the 24 hour rain totals here vary so much from the NWS COOP rain totals I get from the Weather Underground app? I have a rain gauge out on my porch that shows close to the 2.25" number from the app, but the NOAA map shown here says about 3/4" less than that for Escondido. What gives?

    ReplyDelete
    Replies
    1. COOP always needs to be taken with a grain of salt. Most of those are not official reporting stations and/or are automated. There is a lot of room for error. I should also add that the numbers on the map here on the website are not the 24 hour QC'd numbers that the NWS releases.

  23. We had a ton of rain on 12/31 afternoon and mostly very heavy in the evening for an extended period. Curious to check my rain gage after everyone left the party last night, I was happy to see over 3". This morning looking at your site I was surprised to see less than an inch recorded around the San Diego area. I live in Carmel Valley. How could there be that much of disparity? It was really comming down. Less than an inch??

    ReplyDelete
    Replies
    1. There were isolated downpours that moved through the area, so it's possible that the true amounts weren't captured by the reporting stations.

      What kind of rain gauge do you have? These dimensions are required by NWS:

  24. I always wonder the same thing they definitely like to short change the totals it appears. Easier to jack water rates when there's a drought is my guess.

    ReplyDelete
    Replies
    1. You have different types of reporting stations. The official reporting stations need to have official equipment to measure rainfall. There are several automated stations that don't fit the exact specifications, which is why you'll see a variance. One of the few reliable stations happen to be at military bases and airports.

  27. Aron - this is a great site. Love the charts and I keep revisiting to see how we are doing. One suggestion - can the colors across the charts be matched - as sometimes Blue indicates excess rain and sometimes it indicates deficiency (and similarly for Red).
