Meteorologists expect a front of arctic air to flow down this weekend from the northern Rockies into the southern Plains area of the United States, bringing with it temperatures that could set new records in some places, as well as gusty winds and snow.
In parts of Idaho, Montana, Wyoming, Colorado, and the Dakotas, temperatures are expected to be zero degrees Fahrenheit or just a few degrees higher. That's much colder than these areas typically experience in late October. Billings, Montana, for example, has an average low temperature in the mid 30s this time of year.
Early next week, some residents in Oklahoma, Texas, Kansas, and New Mexico should expect nights that dip into the 20s and teens.
Mountain ridges and peaks that face north and east in Washington, Idaho, Montana, Colorado, and New Mexico are likely to see about a foot of snow during the arctic outbreak. Meteorologists are also predicting snow, ice, or other wintry precipitation in the Plains.
