Many Plains, Midwest, and Mid-Atlantic locations observed their first frost or freeze of the cold season over the weekend. A developing coastal low will yield gusty winds across the Coastal Mid-Atlantic & New England this week with a few Coastal Flood Advisories posted for high tides. That system is forecast to stay out-to-sea with respect to precip and its more damaging winds. Across the continent, a coastal system will come onshore in Southern California Thursday bringing rain chances, cool temps, and modest Sierra Snowfall to the state and beyond.
