LANCASTER, CA — The Antelope Valley is heading into one of its most active weather weeks of the season, with a series of storms expected to bring heavy rain, gusty winds, and rapidly shifting conditions through Friday before calmer, colder air settles in for the weekend. Forecast models show multiple rounds of precipitation and wind events that could impact travel, infrastructure, and daily routines across Lancaster, Quartz Hill, and the surrounding communities.
According to the latest 10‑day outlook for the Antelope Valley, the most significant weather arrives midweek, with a strong Pacific system pushing into Southern California late Tuesday and continuing through Thursday.
TUESDAY: CLOUDS BUILD, RAIN ARRIVES OVERNIGHT
Tuesday begins relatively calm, with highs near 63°F and light southwest winds. Cloud cover thickens through the afternoon, setting the stage for the first wave of rain after midnight. Forecasters warn of potential flooding rains, with up to an inch possible overnight.1
Residents in flood‑prone areas—particularly near low‑lying intersections, underpasses, and rural dirt roads—should prepare for possible ponding and reduced visibility during late‑night travel.
WEDNESDAY: HEAVY RAIN, FLOODING RISK, AND GUSTY WINDS
Wednesday is shaping up to be the most disruptive day of the week. The National Weather Service projects 100% chance of rain, with 1 to 2 inches expected across the valley floor.1 Winds from the southwest at 5–10 mph will accompany the system, with stronger gusts possible in exposed areas.
The combination of saturated soil and steady rainfall increases the risk of:
Urban flooding in Lancaster and Palmdale
Mud and debris flows along the foothills
Hazardous driving conditions on the 14 Freeway and Sierra Highway
Delays or cancellations for outdoor holiday events and school activities
Rain tapers to scattered showers Wednesday night.
THURSDAY: MORE RAIN AND STRONGER WINDS
Another round of rain arrives Thursday, with a 90% chance of precipitation and winds increasing significantly—20 to 30 mph, with higher gusts possible.1 While rainfall totals are lower than Wednesday’s, the added wind raises concerns about:
Downed tree limbs
Power outages in older neighborhoods
Difficult crosswinds for high‑profile vehicles on the 14
By Thursday night, showers begin to diminish, though wet roads and lingering gusts remain a concern.
FRIDAY: SHOWERS GIVE WAY TO CLEARING SKIES
Friday brings a 50% chance of morning showers before skies begin to clear. Highs drop to the mid‑50s, and winds remain breezy from the southwest at 15–25 mph.1
This transition day marks the end of the storm cycle and the beginning of a colder, calmer pattern.
WEEKEND OUTLOOK: COLD, CLEAR, AND QUIET
Saturday and Sunday deliver a welcome break from the storms. Sunny skies return, with highs in the mid‑50s and overnight lows dipping into the low 30s.1 Northeasterly winds 10–20 mph may make mornings feel even colder.
Residents should prepare for:
Frosty overnight temperatures
Potential icy patches on rural roads at dawn
Clear but brisk holiday weekend conditions
WHAT THIS MEANS FOR THE ANTELOPE VALLEY
1. Flooding and Road Hazards
With up to 3 inches of rain possible between Tuesday night and Thursday, the valley’s notoriously hard, compacted soil will struggle to absorb water. Expect:
Flooding along Avenue I, Sierra Highway, and low‑lying Quartz Hill roads
Muddy conditions in unincorporated areas
Slower commutes and possible CHP traffic breaks on the 14
2. Power and Infrastructure Concerns
High winds Thursday could strain older power lines and tree canopies. Residents should charge devices, secure outdoor decorations, and prepare for brief outages.
3. Impact on Holiday Travel
Those leaving the valley for Christmas week should anticipate:
Delays on the 5 and 14 due to rain and wind
Reduced visibility in mountain passes
Possible chain controls on the Grapevine if temperatures drop faster than expected
4. Community Preparedness
Local agencies may activate storm‑response crews, especially in areas historically prone to flooding. Residents are encouraged to:
Clear gutters and drains
Avoid driving through flooded intersections
Monitor city alerts and weather updates
BOTTOM LINE
The Antelope Valley is in for a wet, windy, and dynamic stretch of weather through Friday, with the most significant impacts expected Wednesday and Thursday. After that, a cold but quiet weekend offers a chance to dry out—just in time for holiday gatherings.
