WEATHER UPDATE: SATURDAY 10/3/2015

The next storm system is currently passing the Pacific Northwest this morning. You can see the spin in the atmosphere over Oregon on the water vapor satellite loop below:

A few showers will arrive this evening and tonight. Then we will have a chance for spotty on-and-off showers through the day on Sunday. I want to emphasize that it won't be a continuous all day rain event, though if you are going to be outside, you should plan accordingly.

There will be just enough instability in the atmosphere that an isolated downpour or thunderstorm will be possible. Winds will also strengthen on Sunday, especially in the mountains, where gusts could reach 40-50 mph.

Isolated showers will still be possible Monday. Two-day rain totals will be 0.1-0.5" (map below).

NEXT RAIN CHANCE SAN DIEGO: UPDATED FRIDAY 10/2/2015

The storm system still looks on track for Sunday and Monday. A few showers and isolated thunderstorms will be possible on-and-off through Sunday, however, don't expect a complete washout (60% chance for rain). The threat for isolated showers or even a thunderstorm will persist into Monday (40% chance for rain).

Winds will also strengthen on Sunday and Monday, especially in the mountains, where gusts could exceed 30-40 mph.

Temperatures will drop into the mid to lower 70s for both Sunday and Monday, which will feel great!

NEXT RAIN CHANCE SAN DIEGO: UPDATED MONDAY 9/28/2015

A few showers and cooler weather could possibly head this way in about a week.

The European (ECMWF) computer forecast model has been hinting at an inside slider heading our way for this upcoming Sunday (10/4) and Monday (10/5). You can see the track marked by arrows on the maps below. The Canadian computer model has a similar system, but moves things a little slower.

This type of system dives southward into our area quickly, plus, its' track prevents it from tapping into much moisture. They usually result in a few showers, cooler weather and windy conditions (especially in the mountains).

Unfortunately, this system might drift too far east. In fact, the ECMWF ensemble pushes it a little farther east than the operational model. In addition, it isn't as pronounced. It would be nice to see it dive a little farther south.

Regardless, this is definitely something to watch in the coming days. At the very least, we could get a brief break from the heat on Sunday and Monday, though gusty winds could equate to fire danger.
