Storm Totals: December 27th-29th, 2020 ()
A cold low pressure system brought higher than expected rain totals, mountain snow, and gusty winds to the region on Monday. The storm was the most significant storm of the 2020-21 rainy season to-date, ending a mostly dry November-December period up to this point. Rain fell primarily on Monday, with waves occurring in the early morning hours, and showery activity throughout the day - however, the heaviest and most enduring rain fell Monday evening. Falling temperatures during this period also lowered snow levels, with snow falling as low as roughly 3,500 feet above sea level in some locations. Precipitation totals were initially predicted to fall under 3/4 inch in the valleys. Instead, roughly double those amounts were widespread inland, ranging 1.04 inches in Perris to 1.86 inches in Temecula Valley's Wine Country (courtesy of Jim Sappington). The majority of active WeatherCurrents stations received between 1.25 and 1.5 inches of rain by the end of Monday. Some of the wetter lo ...

Storm overperforms throughout region Monday ()
Strong winds, cold temperatures and heavy downpours were main products of a low pressure system moving over Southern California on Monday, while a chance of thunderstorms also remains in the mix going into the night. Although rain is still falling quite heavily at the time of this writing in many locations, precipitation totals so far have largely exceeded original predictions by more than double across most of the region. As of 8 PM Monday, twelve WeatherCurrents stations had recorded over 1 inch of rain since midnight. Hemet, French Valley, and northwest Murrieta had each received over 1.5 inches. Not all locations were nearly this wet, however. WeatherCurrents' stations in Lake Elsinore and Pinon Hills have seen stubbornly low totals thus far, both under 1/2 inch. The station in Lake Elsinore may not be reporting accurately at this time, and we are investigating. Pinon Hills is typically on the drier side. Prior to the storm, predictions had called for between 0.3 and 0.7 inch ...

Unexpected showers make for a damp Christmas Eve ()
Diminishing Santa Ana Winds and cloudy skies dominated Thursday, with some virga from the clouds reaching the ground Thursday afternoon and dampening much of the region with light amounts of rainfall. This shower activity occurred despite the low humidities and dew points present across the region, as well as a very dry lower atmosphere. All active WeatherCurrents stations recorded measurable precipitation by Thursday night, with the exception of Simi Valley to the northwest. Where rain was observed, totals were very light, mostly falling under 0.1 inch. Pinon Hills was noticeably wetter with a total of 0.19 inches. This shower activity followed what was a very dry, windy December to-date. A low pressure system moving into California late Sunday night and into Monday has the potential to bring significant rain, the region's first since early November. The exact timing and intensity of the storm remains uncertain as of Thursday evening, however the National Weather Service is show ...

Pattern alternates between onshore and offshore flow this week ()
Stable northwest flow is responsible for a number of disturbances bringing onshore and offshore flow to Southern California this week, while bringing rain and snow to Northern California. The Santa Ana Wind events last week were followed by strong onshore flow and a deep marine layer Saturday, evening bringing drizzle to some communities. The weather pattern flipped back to offshore flow on Sunday, sending humidities crashing down and elevating fire danger once again. High clouds were drifting over the region by Sunday afternoon. An incoming trough will flip this pattern back to onshore flow yet again Monday, ushering a return of the marine layer as the trough digs into Southern California and Arizona late Sunday night. The upcoming onshore flow pattern will be more consistent throughout the week, with trace amounts of precipitation possible late Sunday night into early Monday morning, and potentially Thursday-Friday. Temperatures are expected to remain within a few degrees of av ...

Santa Ana Winds return later this week, dry weather continues ()
The dry weather that has persisted throughout the region for most of November is expected to continue into at least early December, as stubborn high pressure off the California coast refuses to abate and creates prime conditions for Santa Ana Wind events. While temperatures have been close to seasonal norms in recent days, the weather pattern remains dry overall as Santa Ana Winds ramp up once again later this week, with the potential remaining likely from Wednesday night through Saturday evening. Critical fire weather conditions will be present during this period, prompting the National Weather Service to issue a Fire Weather Watch for inland portions of Southern California, including mountains and foothills. A dry air mass was already in place over the region early this week. East to northeast winds are predicted to strengthen late in the week, with gusts in the 30-40 MPH range throughout the inland valleys and mountains - with more wind-prone areas likely experiencing higher g ...
