The cold snap that had Lodians reaching for extra blankets has officially left town, said David Houk, a meteorologist with AccuWeather. com, a private weather forecasting service.
That chill came from a common system that moved through the northwest during the rainy season, said Houk. Polar air masses invaded and collided with continental air masses, creating a weather pattern both drier and colder than usual. It made for reasonable daytime temperatures, but there was no cloud cover to keep the warm air in at night.
