Upcoming Heatwave in Southern California: What to Expect
As summer approaches, Southern California is set to experience a significant spike in temperatures, with some areas potentially hitting triple digits next week. The region, which recently endured a cooler-than-usual spring and sporadic rainfall, will soon witness a transition to warm, summer-like conditions.
Temperature Forecast
By this Sunday, forecasts indicate temperatures will range from the mid-70s along the coastline to the low 80s in the inland regions of Los Angeles County. Following a brief cooldown on Monday, the rising heat will continue for the rest of the week, as indicated by the National Weather Service.
Come Wednesday, coastal areas are expected to see temperatures in the 80s, while valleys may soar into the 90s. Certain locations in the San Fernando Valley could potentially exceed 100 degrees, raising concerns about possible record-breaking temperatures, as shared by meteorologist Rose Schoenfeld.
“These temperatures are about 12 to 18 degrees above normal,” said Schoenfeld. “We do have temperature variations at different points, but this is a little bit atypical.”
Recent Weather Patterns
Earlier this week, scattered showers brought minimal precipitation to the region—a trend that may not be reprised soon. The light rains yielded less than a tenth of an inch in downtown Los Angeles, while California State University Northridge recorded around a third of an inch. This week’s weather system could mark the end of significant rainfall for the season, as predictions do not suggest any upcoming rain, increasing the chance of a moisture deficit.
Drought Outlook
With only 7.87 inches of rain recorded in downtown Los Angeles since the beginning of the water year on October 1, the average expected for this period is approximately 13.13 inches. The annual rainfall average is around 14.25 inches. Schoenfeld emphasized the dry outlook:
“Through the next 10 days or so there’s no specific chance for rain,” she stated. “And then after that, we’re really not in the rainy season anymore. So long story short, it’s not looking good for any more chances of rain.”
Snowpack Status
Despite the drier-than-normal winter in several areas, California is benefiting from a healthy snowpack. This season is anticipated to yield the third consecutive year of sufficient water supplies in the mountains, a noteworthy milestone not seen in 25 years. As of Friday, the statewide snowpack measured 101% of the historical average, with the northern Sierra Nevada reporting 122%, the central Sierra at 97%, and the southern Sierra at 86%.
Conclusion
Residents should prepare for a significant warm-up as Southern California transitions into what feels like summer. With upcoming heat records on the horizon and ongoing dry conditions, it is essential to stay informed and take necessary precautions against the heat.
