Apple Fire scorches over 26,000 acres near Cherry Valley, Beaumont ()
A wildfire that was first reported late on the afternoon of Friday, July 31st near Cherry Valley and Beaumont, has burned over 26,000 acres as of Tuesday evening. At least twelve structures have been destroyed in the blaze, and one injury as been reported. The fire is burning into an area of wilderness where vegetation is more sparse, limiting fire intensity as of Tuesday. The fire was initially exacerbated by a short, but potent heat wave affecting the region. A thick, dense plume of smoke could be seen across much of the region on August 1st as the fire quickly spread. The return of onshore flow by Tuesday had pushed most of the smoke to the east, towards the deserts. According to Cal Fire, the fire was reported as being 20 percent contained as of 7 PM Tuesday evening. For more detailed information regarding the fire, including information and updates about evacuations, road closures and containment, visit Cal Fire's website.

Rise in temperatures expected this week as high pressure builds ()
Strong high pressure building over the Desert Southwest will be responsible for a moderate heat wave this week, pushing temperatures well into triple-digits inland from Thursday through Saturday. The heat wave has prompted the National Weather Service to issue a Heat Advisory for inland Southern California, including the mountains below 5,000 feet. The deserts will be even hotter under an Excessive Heat Warning effective during the same period. Cool sea surface temperatures are expected to moderate temperatures along the immediate coasts, keeping the effects of the heat wave there minimal. The heat wave follows a period of rather mild temperatures across the region since mid-July, as well as a short heat wave earlier in the month. Monsoonal moisture, often a summer staple in Southern California's inland regions, has been absent so far in 2020, mimicking a similar trend during the relatively quiet summer of 2019. The high pressure ridge is forecast to weaken beginning on Sunday. ...

2019-2020 Rain Season Review and Totals ()
Another weak El Nino pattern established itself in the equatorial Pacific during 2019-2020, resulting in slightly above-average rainfall, with the majority of that rain falling in March and early April. Many locations saw season totals for 2019-2020 that were very similar to the previous year's totals in 2018-2019. The 2019-2020 water year got off to a quiet, dry start amid an inactive monsoon during 2019. The region's first encounters with winter storms would not occur until late November, which would become somewhat frequent through the end of December. Many of the storms during that period were much colder than normal. The pattern changed to mildly warmer and much drier in January 2020, where it remained through the end of February. Season totals had begun their descent into below-average territory. Not long after the start of March 2020, Southern California would see its wettest Spring in decades (however, nearly all rain fell in March and early April only). Storm after stor ...

Unseasonably deep trough brings scattered showers to region ()
A trough of low pressure near the West Coast has brought mild temperatures, mostly cloudy skies and scattered showers - a rarity for June - to the region early this week. Drizzle began falling shortly before midnight on Monday across some parts of the Inland Empire, while measurable precipitation was recorded at seven WeatherCurrents stations by Monday evening. At most WeatherCurrents stations, it was the first recorded instance of rain on June 29th of any year. Where rain did fall, totals were generally under 1/10 inch, ranging from as high as 0.11 inches in Falbrook to 0.01 inch in Lake Elsinore. Inland, primarily the Temecula Valley as well as the Santa Ana Mountains were affected. Light rain continued in southwestern Riverside County well into mid-morning in communities like Murrieta. Gradual warming under building high pressure is forecast to replace the trough this week, as well as the addition of some minor mid-level moisture affecting the mountains and deserts late in th ...

Temperatures spike as heat wave grips region this week ()
A strong ridge of high pressure is responsible for the heat and low humidity across the region this week, which has helped to spark multiple wildfires across the region - sending smoke into the inland valleys. High temperatures this afternoon are several degrees warmer inland than yesterday, with both Lake Elsinore and Wildomar already having reached triple-digits as of this writing. The majority of other WeatherCurrents stations are well into the 90s, with only higher elevations in the 80s. Coastal areas are experiencing roughly the same temperatures as on Tuesday, and cooler in some cases. Smoke from a number of wildfires, burning in Camp Pendleton and elsewhere, have sent smoke into the inland valleys since Tuesday afternoon. This has been exacerbated by very low humidities, mainly in the single digits inland. A cooling trend will begin on Thursday as onshore flow develops, as well as a strengthened marine layer. Warming is expected to resume on Sunday, as high pressure slowl ...
