After weeks of persistent rain for many parts of the United Kingdom, a shift in the weather pattern is bringing a brief respite – and a subsequent warning for potential disruption. While Saturday will see plenty of sunshine, colder air is pushing south, bringing the risk of snow and ice, particularly in northern areas. The Met Office has issued yellow warnings for ice and snow, urging caution for travelers as conditions are expected to deteriorate overnight into Sunday.

The change in weather comes as a welcome break for some, but forecasters are emphasizing the temporary nature of the sunshine. The Met Office states that rain, accompanied by further snow and ice, will spread eastward across the country overnight, impacting travel plans and potentially causing hazardous conditions. This weekend’s weather marks a stark contrast to the recent prolonged periods of wet weather experienced across much of the UK.

Yellow Warnings in Place for Scotland and Northern England

The Met Office has issued yellow warnings for ice and snow across Scotland and northern England, effective from 21:00 GMT on Saturday, February 14, 2026, until 10:00 on Sunday, February 15, 2026. These warnings indicate the potential for travel disruption due to icy surfaces and accumulating snowfall. Rain is expected to turn to snow, initially at lower levels, potentially accumulating a few centimetres before becoming confined to higher ground where up to 15cm of snow is possible, according to the Met Office.

The potential for icy conditions is also a significant concern, with the Met Office warning of possible travel delays and hazardous conditions on roads and pavements. Motorists and pedestrians are advised to exercise caution and allow extra time for journeys. The Met Office is the UK’s national meteorological service, providing weather and climate-related services to the public, government, and businesses, as outlined on the GOV.UK website.

Health Alerts Issued in Response to Colder Temperatures

In response to the forecast Arctic blast, the UK Health Security Agency (UKHSA) has issued yellow health alerts for colder weather across northern England and the Midlands. These alerts, which remain in effect until 08:00 on Monday, February 16, 2026, highlight the potential for “minor impacts on health and social care services, including increased employ of healthcare services and a greater risk to life of vulnerable people.” The UKHSA advises individuals to take precautions to protect themselves from the cold, particularly those who are elderly, have underlying health conditions, or are very young.

The Met Office provides detailed forecasts and warnings on its website, including an interactive weather map and up-to-date information on flood warnings. As of 10:59 (UTC) on Saturday, February 14, 2026, flood warnings were in force for England and Wales, according to the Met Office.

Looking Ahead: Unsettled Conditions to Continue

While Saturday offers a brief period of sunshine, the unsettled weather is expected to continue through the week. The Met Office’s five-day forecast indicates that Sunday will be wet, with outbreaks of rain and some snow. Conditions are expected to turn milder as blustery showers move in from the west. The outlook for Monday to Wednesday suggests sunny spells and heavy showers on Monday, a drier day on Tuesday with sunny spells, and rain arriving in the southwest later, potentially lingering through Wednesday.

The Met Office, established in 1854, is an executive agency of the Department for Science, Innovation and Technology, as detailed on Wikipedia. It plays a crucial role in providing weather and climate services to the UK, supporting government planning and public safety.

As the weekend progresses, it’s crucial to stay informed about the latest weather updates and heed the advice of the Met Office and the UKHSA. The changing conditions require vigilance and preparation to ensure safety and minimize disruption.

California is preparing for its coldest storm of the season, set to arrive Sunday and lasting through at least Wednesday, bringing the promise of much-needed snow to the Sierra Nevada, but too raising concerns about potential flooding, particularly in areas recently impacted by wildfires. The storm represents a dramatic shift in weather patterns for the Western United States, which has experienced unusually warm and dry conditions throughout much of the winter.

The anticipated precipitation is critical for replenishing the state’s snowpack, currently at a significantly low level. As of February 12, 2026, the California Department of Water Resources reports the snowpack is only 55% of its average for this time of year. This lack of snowfall has raised concerns about water availability during the drier months, as the snowpack serves as a vital freshwater source for the region.

The National Weather Service warns of a prolonged period of wet weather across California and parts of the Southwest, with locally heavy rainfall and showers expected. Burn scars from previous wildfires are particularly vulnerable to flooding, and residents in those areas are urged to be prepared. The heaviest rainfall is forecast for coastal and Southern California, as well as the Sierra foothills at lower elevations.

Meteorologist Rob Shackelford of weather.com explained that the shift in weather is due to a change in the jet stream. “Most of the winter has seen the jet stream riding well north into western Canada, then plunging southward into the East,” Shackelford said. “Next week, the jet stream will take its sharp southward plunge into the West, leading to cooler temperatures and an influx of much-needed rain and snow.”

Sierra Nevada Expected to Receive Feet of Snow

The Sierra Nevada mountain range is expected to be the focal point of the storm, with forecasts calling for feet of snow. This substantial snowfall will not only benefit the state’s water supply but also present significant challenges for travel. Conditions in the higher terrain are expected to become increasingly difficult, potentially becoming impassable at times. The Sierra Nevada, a 400-mile long mountain range between California’s Central Valley and the Great Basin, is a crucial component of California’s water infrastructure. According to the Sierra Nevada Wikipedia page, the highest point in the range is Mount Whitney, reaching an elevation of 14,505 feet.

Western Snowpack at Historic Lows

The need for this storm is underscored by the dire state of the snowpack across the broader Western United States. The National Resources Conservation Service (NRCS) reports that dozens of locations from Colorado and Utah to the Pacific Northwest are experiencing snowpack levels lower than they have been in at least a decade. Colorado, in particular, is facing its lowest snowpack on record, requiring significant snowfall just to reach normal levels, according to Colorado Snow Survey Products.

The importance of the snowpack extends beyond recreational activities. It serves as a natural reservoir, slowly releasing water during the spring and summer months, providing a critical source of freshwater for agriculture, communities, and ecosystems throughout the West.

Why the Shift in Weather Patterns?

The unusual weather pattern this winter, characterized by sustained warmth and minimal precipitation, was driven by a persistent northward shift in the jet stream. This allowed warmer air to dominate the West, suppressing storm systems. The anticipated change in the jet stream’s path will bring a return to more typical winter conditions, delivering the much-needed moisture the region desperately needs.

The storm’s impact will be closely monitored in the coming days. While the snowpack boost is welcome news, officials are also preparing for potential flooding and travel disruptions. Residents are advised to stay informed about the latest forecasts and heed any warnings issued by local authorities.

As the storm moves through the region, attention will turn to assessing the actual snowfall totals and the resulting impact on the snowpack. The coming weeks will be crucial in determining whether this storm is enough to significantly improve the water supply outlook for the West.
