A powerful storm system, that has weather officials referring to as a “bomb cyclone,” is set to impact the Sacramento region this week, bringing significant rainfall, gusty winds, and cooler temperatures. The National Weather Service (NWS) advises residents to prepare for wet conditions and exercise caution during commutes.
A bomb cyclone is a rapidly intensifying storm that occurs when atmospheric pressure drops significantly within 24 hours, a process known as bombogenesis. These storms are often marked by strong winds, heavy rainfall or snowfall, and severe weather conditions. Bomb cyclones develop when cold, dry air collides with warm, moist air, creating an intense low-pressure system.
The initial wave of showers is expected to arrive Wednesday afternoon, with rain likely after 1 p.m. There’s an 80% chance of precipitation during the day, with temperatures reaching a high near 60 degrees. South winds are forecast at 6 to 10 mph, with gusts up to 20 mph. Rainfall amounts are predicted to be less than a tenth of an inch, potentially leading to slick roads during the evening commute.
The storm intensifies on Thursday, bringing a 50% chance of showers throughout the day. Temperatures will reach a high of around 61 degrees, with calm winds becoming southwesterly at about 5 mph by the afternoon. By Thursday night, rain chances increase to 60%, with periods of heavier showers possible after 8 p.m. Overnight lows are expected to dip to around 45 degrees.
Lingering showers are expected on Friday, particularly in the morning, with a 40% chance of rain. Partly sunny skies are anticipated by the afternoon, with daytime highs near 57 degrees. Friday night will bring drier conditions, with a 20% chance of rain early in the evening before clearing skies take over. Overnight lows could drop to around 38 degrees.
The Sierra Nevada is expected to experience significant snowfall due to the storm system. A Winter Storm Warning is in effect from 4 p.m. Wednesday to 10 p.m. Thursday. Snow levels are forecast to drop to 5,500 feet, with accumulations of 2 to 4 inches at higher elevations. Wind gusts could reach up to 30 mph, creating hazardous travel conditions.
The NWS advises travelers to be prepared for winter driving conditions in the mountains and to carry chains. Residents in the Sierra foothills should also be alert for potential impacts from the storm.
This series of storms marks the first significant rainfall in weeks for the Sacramento region, a welcome change for the parched landscape where area reservoirs such at Folsom have reached their lowest levels of the year. The welcomed precipitation does pose a potential challenge for outdoor plans and daily commutes, however.
The NWS is reminding residents to stay informed about changing weather conditions and prepare for potential travel delays during peak commute hours. Gusty winds on Wednesday and saturated roads throughout the week may contribute to hazardous driving conditions.
