A wall of wintry mix and rain was pushing into parts of the East on Sunday as a strong arctic high pressure system was forecast to help fuel snow and ice for a large part of the interior Northeast into Monday, forecasters warned.
AccuWeather meteorologists advised that travel on some highways could be difficult Monday and that flight delays because of deicing operations were possible. A strong dome of high pressure sliding from the Great Lakes toward New England was to blame.
“Some record high barometric pressure readings may occur,” AccuWeather Lead Long-Range Meteorologist Paul Pastelok said.
High pressure is usually associated with relatively cool, dry and sunny conditions. However, the lingering effects of the high pressure area will conspire with an approaching storm from the Midwest, creating a “wedge” of cold air as moisture arrives from the Midwest storm, AccuWeather said in its forecast. The storm dumped almost three feet of snow in areas near Buffalo, New York, last last week.
