NEXT RAIN CHANCE SAN DIEGO: UPDATED SATURDAY 12-29-2018

Another blast of cold air is headed our way for New Year's Eve. The leading edge of this front could trigger isolated showers in our area Monday afternoon and into Monday night (60% - I've increased the rain chances). There isn't much moisture with this system, so rain amounts will be limited (less than 0.1"). Snow levels will drop to 3,000-4,000 feet by Monday night, so some local mountains like Cuyumaca and Laguna could see light snow (1-3" possible).

Cold mornings will persist through the week, with lows easily dipping into the 30s Wednesday and Thursday.

It's looking like the weather pattern will shift late next week. A large system will move in off the Pacific and bring rain around Sunday-Monday (1/9 to 1/10). This is a long way away, so the projected track of this system will shift as is approaches. I'll keep an eye on it and bring updates in the coming days.

NEXT RAIN CHANCE SAN DIEGO: UPDATED 12-23-2018

A small but potent storm system will dive out of the Gulf of Alaska and move into our area on Christmas Day (seen on the satellite loop below).

Patches of light rain and drizzle will develop Monday night around midnight. Showers and isolated downpours will then be possible Tuesday morning and last into early Tuesday afternoon. The atmosphere will be somewhat unstable, so there could be a random rumble of thunder. The rain chance quickly diminishes after sunset. Rain totals will range from 0.25" to 0.75" (map below).

Snow levels will be 7,000 to 8,000 feet on Tuesday morning, then drop to 5,500 to 6,500 Tuesday evening. So the top of Cuyamaca could see a little snow.

I'm still expecting cool air to descend into our area for the rest of the week, with Friday being the coldest so far this season. In fact, latest data is showing a reinforcing blast of cold air arriving on New Year's. I'll bring more updates as the front approaches.



NEXT RAIN CHANCE SAN DIEGO: UPDATED TUESDAY 12-18-2018

A big shift in the weather pattern is headed this way.  Temperatures will remain mild for the next couple days, then a front will pass the area on Friday and push our temperatures down a tad for the weekend.

A much more powerful system will move in on Christmas Day. Scattered showers will be possible Tuesday and into Wednesday. Moisture is limited with this system, so I'm not expecting a lot of rain. Snow levels will be fairly low, so some local mountains will see some snow.

The biggest story will be the cold air moving in for the rest of next week. You can see on the maps below how cold air overspreads the entire Western United States. It will be the coldest of the season and will probably persist for the rest of December.

This is still several days out, so I'll keep watching the pattern develop and bring updates when necessary.

NEXT RAIN CHANCE SAN DIEGO: UPDATED MONDAY 12-17-2018

There is still a slight chance for a few showers late this afternoon and into early tonight. The front is weak and there isn't much moisture associated with this system, so rain amounts will be low...if you see any.

I'm also watching for a slight chance for rain early next week. It doesn't look like a major storm, but still worth tracking.

NEXT RAIN CHANCE SAN DIEGO: UPDATED TUESDAY 12-11-2018

Over the past few days I've been closely watching out over the Pacific Ocean. The weather pattern is extremely disorganized right now. There are several small systems, including one that is overhead our area this morning. You can see clouds in our area in the first two satellite images below.

Unfortunately this system isn't too strong. There also isn't much moisture available to produce any instability or rain. You can see on the third satellite loop below that all the moisture (indicated by blue, green and red) is staying bottled up in the tropics. Chances for rain today are extremely slim. I'm expecting skies to clear this afternoon and evening.

We will see the same thing happen on Friday and then again next Sunday/Monday. Storm systems will approach our area and weaken, so we will see clouds, but probably no rain. Right now I'm leaving the rain chances at 20% for both days, but that might be generous.

Ultimately we will need to see a shift in the weather pattern to allow a deeper and stronger storm to bring rain back to San Diego.

NEXT RAIN CHANCE SAN DIEGO: UPDATED MONDAY 12-3-2018

There are no big changes with the forecast for this next round of rain. The storm system is easily spotted on the first satellite loop below.

I'm expecting rain to move into our area between 9 AM and 12 PM Wednesday. Periods of rain will persist into Wednesday night and through the day on Thursday. The atmosphere will become unstable as the core of the system passes overhead on Thursday. Isolated thunderstorms will be possible late Thursday morning into Thursday evening. This brings the potential for heavy rain for some areas. Also, there is a mild atmospheric river with this system, which enhances the rain amounts (second loop below).

Rain totals could range from 1 to 2" with isolated areas getting more, especially in the mountains (map below). Snow levels will be above 8,000 so I'm not expecting snow in local mountains. However, the Sierra's to the north will get another significant snowfall (map projections below).

NEXT RAIN CHANCE SAN DIEGO: UPDATED SATURDAY 12-1-2018

We will have a quick chance for a shower or two this afternoon and early tonight (4 PM to 1 AM). The chance for rain diminishes tonight and Sunday will be dry and cool. Rain totals will be low: less than 0.1" for coastal/inland areas, and near 0.25" in the mountains. Snow levels will drop as low as 6,000 feet, so the top of Cuyamaca could see a little snow.

I'm watching a bigger system brewing in the Gulf of Alaska. There is a ton of jet stream energy bottled up there (seen on the satellite loop below). Eventually this will organize into a storm system that will dive into our area for next workweek.

I'm expecting showers and isolated downpours to develop Wednesday and persist into early Thursday. The system is still far away, so the forecast will need some fine tuning in the coming days. Regardless, the stormy weather pattern persists, which is great news!

NEXT RAIN CHANCE SAN DIEGO: UPDATED WEDNESDAY 11-28-2018

The next storm system remains on track. You can see it spiraling in the Pacific as it races our way (satellite image below). Scattered light showers will develop tonight and into Thursday morning (5 PM tonight to 11 AM Thursday). Heavier rain will arrive by midday Thursday as the core of the system passes overhead.

Periods of rain and isolated downpours will be possible from 10 AM to 6 PM on Thursday. Isolated thunderstorms will also be possible. Most rain will taper Thursday night, though a stray shower is possible in the mountains into Friday afternoon.

There is a moderate atmospheric river associated with this system, so the rain potential is high, especially if we see thunderstorms. Rain totals will range from 0.5 to 1.5" for coastal and inland areas. Mountain regions will see 1.5 to 3.0".

Snow levels will remain high with this system (above 8,000 feet), so local mountains will not see snow, though there will be accumulations in the San Bernardino Mountains at higher elevations (3 to 6" possible, over 12" at the highest peaks). The Sierra's are going to get pounded with snow, which is great news for the drought! Rain and snow projections are posted below.

We will have another quick chance for rain Saturday afternoon. Snow levels could dip as low as 6,000 feet with this next system, so the very top of Cuyamaca could see some snow.

I'm also watching another big storm heading this way for next Tuesday. I'll bring more updates as it approaches.




NEXT RAIN CHANCE SAN DIEGO: UPDATED SUNDAY 11-25-2018

A strong storm system will bring heavy rain across most of California for the upcoming workweek. A lot of energy is diving down the west side of a large system in the Gulf of Alaska (seen in the satellite loop below). This energy will deepen and head to the West Coast on Wednesday. Computer forecasts have been fairly consistent with this scenario, in fact, the latest European model has this system deeper and stronger.

I'm expecting rain to start in Southern California on Wednesday night. We will then see periods of rain and isolated downpours through the day Thursday. The rain will taper Thursday night into Friday morning. Rain totals should range from 0.5" to 1.0", though some areas in the mountains will get more. Northern California and the Sierras will get some much needed rain (GFS computer forecast of rain totals posted below).

Snow levels will be very high in Southern California, so I'm not expecting accumulations, but you can see on the map below that the Sierras will receive significant amounts of snow from this system.

I'll continue to watch the situation and bring updates as the system approaches.

NEXT RAIN CHANCE SAN DIEGO: UPDATED FRIDAY 11-16-2018

There are signs that our dry pattern is about to erode in the coming days. On the satellite loop below, you can spot a storm system spinning in the central Pacific. This system will miss us to the south, however, another storm will follow right behind. It's currently over the Aleutian Islands of Alaska (also seen on the satellite loop below). This system could possibly bring rain to Southern California by next Wednesday or Thursday (Thanksgiving). It's still thousands of miles away, so a lot can change in the next few days, but at least it's a sign that rain season might begin soon. I'll have more updates in the coming days.

NEXT RAIN CHANCE SAN DIEGO: UPDATED FRIDAY 10-12-2018

There aren't many changes to my forecast from yesterday. The remnants of Sergio continue to get pushed to the east of our area by an upper level storm system that is settling overhead our region tonight and tomorrow.

This system will bring enough instability to the atmosphere that a few showers and isolated thunderstorms will be possible tonight and into Saturday. I'm increasing the rain chances to 60% for coastal and inland areas for tonight through midday Saturday. Rain chances are 70% in the mountains tonight and lingering through Saturday night.

Rain totals (posted below) won't be too impressive, except for the San Bernardino mountains.

Sunday is looking dry and wonderfully cool. Enjoy!


NEXT RAIN CHANCE SAN DIEGO: UPDATED THURSDAY 10-11-2018

Tropical storm Sergio will continue to weaken as it moves to the northeast across the Baja. It is being deflected by a storm system that is moving into Northern California this morning. You can spot both features in the satellite loop below. The other system in the central Pacific, which is also seen in the satellite loop, will remain stalled over the ocean waters.

I should preface this outlook: computer forecast models are notoriously terrible with predicting storm systems that deflect tropical storms or hurricanes. They usually exaggerate the impact of the system.

Regardless, most computers are still showing a chance for rain throughout Southern California Friday night into Saturday. This will be associated with the system in Northern California as it settles overhead. Rain totals won't be too impressive (map of totals below), however, a quick shower or even a downpour/thunderstorm can't be ruled out early this weekend. There is plenty of tropical moisture and atmospheric instability, so I'll put rain chances at 40% for the city and 70% for the mountains and East County.

Don't cancel you outdoor plans Saturday, just keep an umbrella handy. Sunday is looking dry and pleasantly cool.




NEXT RAIN CHANCE SAN DIEGO: UPDATED 12 PM SATURDAY 9-29-2018

Hurricane Rosa is currently a category 2 hurricane with sustained winds of 105 mph. It's moving to the north at 12 mph. Most computer forecasts have this storm weakening and moving to the northeast over the next couple days.

Rosa will eventually be deflected by a system in the North Pacific. You can spot both Rosa and the storm system on the satellite loop below. I've also posted all of the computer data below.

Although the core of Rosa's remnants will be pushed east of Southern California, we could still see a quick shower or downpour from an outer band on Monday and Tuesday. In addition, there is a chance for a shower on Wednesday as the storm system that is deflecting Rosa passes overhead.

I'd put rain chances at 20% Monday, 30% Tuesday and 40% Wednesday. At this time, overall rain amounts aren't looking too impressive in San Diego County, however, I will be watching Rosa very carefully regardless.






WEBCAM IMAGE OF FIRE NEAR ALPINE: UPDATED 2 PM 7-6-2018

You can see smoke from the fire near Alpine. The camera is on top of Lyons Peak looking north.

NEXT RAIN CHANCE SAN DIEGO: UPDATED FRIDAY 4-27-2018

A storm system will move into our area early next week and bring a chance for a few showers late Monday through early Wednesday.

This storm will dive out of the Gulf of Alaska and down the back of the current system stalled in the Pacific Northwest (seen on the satellite loop below). It's not the ideal path for a significant rain event, so moisture levels will be limited. Most areas will see less than 0.25", but we'll take whatever we can! The computer forecast rain totals are included below.
