WEATHER UPDATE: 9 PM MONDAY 1/26/2015

A renegade shower will be possible tonight, however, it looks like most of the rain has pushed north of our area. A few showers could return on Friday.

NEXT CHANCE FOR RAIN IN SAN DIEGO: UPDATED SATURDAY 1/24/2015

In my last blog post, I mentioned about the possibility of a storm sneaking under a ridge in the jet stream, however, I didn't expect something like this. You can see on the maps below (the storm is indicated by the arrow). This system is going backwards! It will eventually move into our area Monday evening into early Tuesday

Moisture will be limited, plus the storm will be weakening, so only a few showers will be possible. The atmosphere will be somewhat unstable, so an isolated downpour can't be ruled out.

Another chance for rain could arrive by the end of the workweek.





NEXT RAIN CHANCE IN SAN DIEGO: UPDATED SATURDAY 1/17/2015

An upper level ridge in the jet stream is going to govern our weather for the next couple weeks. You can spot it on the map below, indicated by the big red blob.



This ridge will briefly weaken around Wednesday (1/21) of the upcoming workweek.We will see some clouds as a weak system passes overhead, however, the air will be bone dry. In other words, the chances for rain are very slim.

The ridge will strengthen heading into next weekend (notice the red area on the map below), which means more dry and warm weather. If the ridge drifts far enough north into the Gulf of Alaska, then we could possibly see a system sneak underneath. Otherwise, it appears that we will remain mostly dry for the rest of January.


SAN DIEGO RAIN TOTALS: SUNDAY 1/11/2015



WEATHER UPDATE: 9 AM SUNDAY 1/11/2015

Inland and coastal showers should slowly taper over the next several hours. The chance for rain in the mountains will linger into the evening. I'll post rain totals once the rain has completely exited the region.

NEXT RAIN CHANCE SAN DIEGO: UPDATED THURSDAY 1/8/2015

As expected, the computer forecasts were terrible with the placement of that cut-off storm system that I talked about in my previous blog post. The computers have been equally bad at forecasting the two small systems following behind (highlighted on the maps below).

The first system will pass tomorrow, however, moisture is limited. We will see clouds, but the chances for rain are slim to none.

The next system moves in Saturday evening into Sunday. This will bring a chance for a few showers. I'm not expecting a complete washout, but you should definitely plan accordingly if you plan on being outside during this time.

Skies will quickly clear and we will be dry and mild for most of next workweek.



NEXT RAIN CHANCE IN SAN DIEGO: UPDATED SATURDAY 1/3/2015

A powerful ridge in the upper atmosphere will control our weather pattern for the next couple weeks. It will bring warmer and drier than average conditions. It's strong enough to deflect a storm system in the Pacific on Monday. You can spot both features on the map below (the ridge is red, the storm system is blue)


A weak system will drift to the south of us on Thursday (marked on the map below). This system is cut off from the upper level flow. These type of systems are very difficult to forecast because they have a tendency to float around. There is the slightest chance for a shower by the end of the week (Thursday or Friday), but don't hold your breath.


Afterwards, the ridge builds back in next week. Which decreases any chance for rain.


We might have to wait until the middle of the month to have a chance for significant rainfall. There are hints of the weather pattern shifting by then. Otherwise, enjoy the nice weather!

SAN DIEGO 2014 RECAP: TOTAL RAINFALL & TEMPERATURES

2014 in San Diego was extremely dry and was the warmest on record.

We ended up with 7.77" of rainfall in the city, which is below the normal value of 10.34". We had more rain than 2013, where we received 5.57".

2014 was the warmest on record. The average temperature was 67.6, which breaks the old record of 67.2 set back in 1984.

The first map below shows total rainfall across all of California. The second map shows the percentage of normal, which helps to enhance which areas were wetter and drier.

The third map shows temperature departure from normal. The fourth map shows the ranking vs historical records. You can see that most of California saw record heat.

The last two maps shows how we compare to the rest of the United States. Most of the Southwest was dry while the Pacific Northwest and Northern Rockies were wetter than normal. Temperatures were warm for the western third of the country while the eastern two thirds were cooler than normal.
