NEXT RAIN CHANCE SAN DIEGO: UPDATED THURSDAY 1-30-2020

Warm weather will continue for the next two days with highs climbing to near 80 on Friday and Saturday. A fast-moving storm system will blast from the north on Sunday and bring a quick chance for rain Sunday evening and Sunday night. Most of the rain will be gone by late Monday morning. The start of next workweek will be quite chilly with morning temperatures dipping into the 30s Tuesday and Wednesday!

I'm watching for another storm system that could potentially bring more rain around Sunday 2/9 into Monday 2/10. I'll bring more updates in the coming days.

NEXT RAIN CHANCE SAN DIEGO: UPDATED SUNDAY 1-12-2020

A storm system will clip our area at the end of the workweek and bring a quick chance for some showers. The rain chance will arrive Thursday afternoon and persist into the night. Most showers will exit by Friday morning. Rain totals will remain below a half inch for most areas.

Snow levels will drop to 4,500-5,000 feet by Thursday night, so some of the taller local mountains will get light snow.

I'll continue to watch the scenario and bring updates if there are changes to the forecast.

SAN DIEGO 2019 RECAP: RAINFALL & TEMPERATURES

Temperatures were generally near normal throughout 2019. April and December were a little warmer than average, and February was cold. After several years of drought and extremely warm weather, this was a relief.

The big story was the rainfall. January, February, November and December were all significantly above average for rain. We ended up almost five inches above average for the year!

I've posted all the data below, along with month-by-month rain totals across San Diego County. I've also posted temperature and rain data for California and the entire United States.

	Average Temperature	Departure From Normal	Total Rainfall	Departure From Normal
Jan	58.7	1.6	2.80	0.82
Feb	55.7	-2.2	3.42	1.15
Mar	60.5	1.1	1.23	-0.58
Apr	64.3	2.5	0.16	-0.62
May	63.8	-0.2	0.80	0.68
Jun	66.3	-0.1	0.01	-0.06
Jul	70.1	0.1	0.00	-0.03
Aug	71.6	0	0.00	-0.02
Sep	72.4	1.8	0.11	-0.04
Oct	67.9	1.2	0.00	-0.57
Nov	63.2	1.9	2.72	1.71
Dec	58.7	2.2	4.03	2.5
Total	64.4	0.8	15.28	4.94

2019 rain totals across California

This map shows the percent of normal rainfall. It's a great way to spot which locations had higher than average rainfall. As you can see, all of California was above average.

This map compares 2019 to previous years. 2019 ranks in the top ten wettest on record for many locations throughout California. In fact, parts of northeast CA saw record rainfall.

Temperatures were generally normal for most of California in 2019. There were some spots in central and northern CA that were above average, while some spots in southern California were below average.

When you compare 2019 to previous years, you can see that some parts of central and northern California ranked in the top 33% for warmth. 

Looking across the United States, the highest rain totals were across the South and Southeast.

When you show it as a percent of normal rainfall, it's easier to see which areas were dry and wet. Most of the Southwest was above average, though it was dry in Washington and Oregon. The Northern Plains were significantly above average. Conversely, Texas was mainly below average.

Ranking 2019 against previous years shows that most of the Northern Plains received record breaking rainfall. Parts of the Pacific Northwest and also Texas ranked in the top 10% driest on record.

NEXT RAIN CHANCE SAN DIEGO: UPDATED TUESDAY 1-7-2020

We are currently stuck in a weather pattern where the storm track is mainly to our east. Over the next several days, systems will dive southward along the coastline and bring us an occasional chance for some showers. Unfortunately, none of these will bring substantial rainfall.

The first system will clip the area on late Thursday into Thursday night (40%). Another arrives over the weekend, though the rain chances are less than 20% both Saturday and Sunday. Yet another one passes next Wednesday/Thursday (still too early to give realistic rain chances).

Although this isn't a rainy pattern, it will keep temperatures below average. It looks like this pattern will begin to erode by the end of next week. It will be interesting to see what comes afterwards.
