DISCUSSION: As more moisture and energy gradually makes its way across a good portion of the central and eastern Pacific Ocean, there will be a renewed threat for persistent periods of heavy rainfall across a good portion of southern and some parts of central California by next week. The reason for this threat will be an influx of abundant Pacific moisture and jet energy; bolstering the atmospheric dynamics that will help support the larger-scale environment conducive for the generation of heavy rainfall. Moreover, as discussed in the actual Facebook post (courtesy of the National Weather Service office located in San Diego, California), "Long range forecasts are suggesting the return of a rainy pattern in SoCal toward the end of next week, as a dip in the jet stream brings the storm track southward. Current forecasts from the Climate Prediction Center (CPC) suggest a 68% chance for above normal rainfall from February 16th through February 22nd."
