NEXT RAIN CHANCE SAN DIEGO: UPDATED SUNDAY 11-24-2019

I've sifted through all the latest data this morning. A forecast like this is always challenging because the slightest shift in storm track can dramatically affect rain and snow totals. Computer forecasts have been a little inconsistent with the track of the core of this system. There has been some wobbling east and west, though this is to be expected. Regardless, not much has changed with the forecast - rain is likely for the upcoming week with significant snow in the mountains.

Showers could start as early as late morning Wednesday (40%), then rain is likely Wednesday afternoon/evening (100%). Periods of rain with embedded heavy downpours will then persist on-and-off through the day Thanksgiving (100%). It will be a raw and windy day. Wind gusts in the mountains will be intense.

Intermittent showers will linger on Friday (80%). The rain chance then diminishes Friday night.

Snow levels will start at 7,000 feet Wednesday morning, then steadily drop through the day to 5,000 feet Wednesday night. Snow levels will range from 4,000 to 5,000 Thursday, then fall as low as 3,000 feet on Friday. The tallest mountains in San Diego County could easily get a few inches. Peaks in the San Jacinto and San Bernardino mountains should exceed a foot of snow.

I've included the latest computer forecast for rain and snow totals. This system is still far away, so there will be some adjustments to this forecast in the coming days.
