The previous blast of arctic air that broke records along the East Coast for the past two weeks may finally be departing.
Heavy rain, gusty winds, and mountain snow will impact central and southern California through Tuesday; this may result in debris flows and mudslides due to recent wildfires.
The cold temperatures in the East will moderate, but areas of freezing rain are expected from the Missouri Valley to Mid Atlantic. Locally heavy rainfall is also possible over the lower Mississippi Valley.
Meteorologists say a warm-up is expected in New Hampshire, the summit of Mount Washington registered minus 36 Saturday morning, with a wind chill of minus 94, tying for the second coldest place in the world. Boston tied a low-temperature record set more than a century ago in 1896 of minus 2.
Now, this bone-numbing air is set to push out of the region. Boston temperatures should return to a more seasonable low 30s.
