NEXT RAIN CHANCE SAN DIEGO: UPDATED THURSDAY 1-23-2024

A mild La Nina has dominated our weather pattern so far this rain season. For this reason, I was quite skeptical when computer forecasts showed rain for this weekend. However, the computers continue to show rain heading this way, so it's impossible to ignore.

The satellite loop below shows a chaotic pattern over the Pacific. There's a decaying large system north of Hawaii and another vortex spinning far off the coast of the Pacific Northwest. I'm keeping an eye up north, where eventually a piece of energy will dive southward out of the Gulf of Alaska and buckle the upper level flow pattern (the jet stream). 

A system will emerge and bring us showers by Saturday afternoon and evening. Intermittent showers will then be possible through the day on Sunday. This system is somewhat moisture-starved, so rain totals will be limited. Regardless, we'll take what we can get.

Isolated showers will persist into Monday as the core of the system settles overhead. There's enough instability in the air to support isolated thunderstorms, which could bring a brief heavy downpour and possibly some small hail.

The rain chance diminishes Tuesday morning. Snow levels will dip low enough on Monday for some snow in local San Diego mountains. Levels could dip to 3,500 during that time period. Be sure to keep an eye on road conditions if you plan to travel in higher elevations on Sunday and Monday.

I've posted the computer projected rain and snow totals below.

I'm also keeping an eye on another small system around the 2-5 to 2-8 time frame, though this is far away and the overall weather pattern is a dry one. We'll see!

 

SAN DIEGO 2024 RECAP: RAINFALL AND TEMPERATURES

Overall temperatures were cooler than normal throughout 2024. July, August and September were the exceptions with warmer than normal temps.

It was a wet start to the year with heavy rains in January, February and March, though we haven't received much rain since. The overall total puts us in a surplus for the year.

	Average Temperature	Departure From Normal	Total Rainfall	Departure From Normal
Jan	56.1	-2.3	3.65	1.67
Feb	57.9	-1.1	4.58	2.38
Mar	59.5	-1.2	2.54	1.08

Dec	57.7	-0.2	0.01	-1.66
Total	64.0	-0.8	11.16	1.37

Here are the rain totals across the state.

Rain totals were generally above average across the western side of the state. Conditions were drier than normal along the Sierras and to the southwest, where conditions were exceptionally dry.

This map further shows the disparity of rainfall across the state, where the Northern CA saw much above rainfall, where Southwest CA saw much below normal.

This is an interesting map, which shows temperatures across the state. It was cooler than normal from Santa Barbara down to San Diego. These coastal areas were the exception. Most of the state experienced warmer than normal conditions.

In fact, the map below shows that a lot of areas saw record-breaking heat along the Sierras and to the southwest.

Here are the precipitation totals across the country.

The map below shows the percentage of normal precip. A lot of the Southwest was very dry, while parts of the South saw excessive rainfall due to hurricane season.

Parts of the Northern Midwest, Texas and Louisiana had record-breaking precipitation.

It was an extremely warm year across the entire United States, where almost every state experienced above average temperatures.

This map shows which areas saw extraordinary heat. Much of the Northeast, Texas and Southwest experienced record-breaking heat (2024 was the hottest on record).

 
As always, here are the monthly rain totals across our area.
