There will be a little wintry intrigue early this week, though. A fast-moving clipper system is expected to slide through tonight into Tuesday, bringing a brief burst of snow across parts of the state. Upstate and higher-elevation regions could see some accumulation, especially east of Lake Ontario, in the Tug Hill Plateau and the Adirondacks, where several inches are possible.
WeatherLight to modest early week snow refreshes the Washington and Oregon Cascades, with the biggest boost focused on Mount Baker, before a quieter midweek and a warmer, wetter pattern building late in the period. A weak system Monday night into Tuesday drops a few inches of mid-density snow on the northern Washington crest and around an inch or so elsewhere, with snow levels generally near 3,000 to 4,000 feet and all featured resorts remaining closed and quietly building base.
The forecaster has warned that an icy northerly wind means temperatures in some parts of the country could drop to -10C as the first cold snap of the season takes hold. In London, temperatures will remain at around 5C through the day until Friday, with colder conditions at night. The capital felt significantly colder throughout Monday despite sunny spells throughout the day.
